Description

Multifunctional environmentally friendly stove

A gas stove, especially a multifunctional environmentally friendly gas stove.

Incinerators are a common device used in daily life and industrial production, their primary function being to burn various combustible materials. Existing incinerators have a dedicated combustion chamber within the furnace body, which serves as the core area where the combustion reaction occurs. During operation, operators feed various combustible materials into the combustion chamber through a feed port, such as gold paper commonly used for sacrificial offerings, branches and leaves from gardening, and daily paper waste, allowing them to burn in a high-temperature environment.

However, existing combustion furnaces often present some challenging issues. One is the tendency to smolder. This occurs when air circulation is poor during the combustion process, preventing the combustibles from adequately contacting oxygen and resulting in incomplete combustion. Incomplete combustion not only wastes energy but also produces a large amount of harmful gases and unburned materials, polluting the environment. Furthermore, smoldering and incomplete combustion reduce overall combustion efficiency, requiring more time and energy to complete the combustion task, reducing production efficiency and increasing operating costs.

Traditional combustion furnaces typically feature a three-tiered design. The bottom tier collects ash, acting like a storage box, collecting the remaining residue for easy disposal. The middle tier, located above the bottom tier, is the primary location for burning combustibles, generating the flames and heat. The top tier dissipates the heat generated during combustion, ensuring pressure balance and heat transfer. Under normal circumstances, this three-layer structure functions independently and in coordination with each other. During the combustion of combustibles in the middle layer, air can be transported upward toward the middle layer by utilizing the heat circulation in the bottom layer, thereby improving the combustion efficiency of the middle layer to a certain extent.

However, problems arise when a large amount of combustible material accumulates in the middle layer. As the amount of combustible material increases, the gaps between the combustibles become increasingly compressed, making it difficult for air to flow smoothly through the stacked layers. This insufficient air supply prevents the central portion of the stacked combustible material from receiving sufficient oxygen, significantly reducing combustion efficiency there and exacerbating problems such as incomplete combustion and smoldering.

In summary, given the shortcomings of existing combustion furnaces, there is an urgent need for a new technology to fundamentally address problems such as poor air circulation and low combustion efficiency, thereby meeting the growing demand for environmental protection and efficient combustion.

This invention primarily provides a multifunctional, environmentally friendly combustion furnace, particularly suitable for processing at least one combustible material. The multifunctional, environmentally friendly combustion furnace comprises an outer shell, a carbonization chamber, a carbonization chamber cover, a furnace cover, a base, an inner shell, a first furnace sieve plate, a second furnace sieve plate, an ash collection tray, two guide ramps, a first outer furnace door, and a second outer furnace door. The outer shell has a lower opening and a concave storage space above it. The storage space has a plurality of first ventilation holes around its perimeter and on its bottom. The carbonization chamber is disposed within the storage space of the outer shell and is used to treat exhaust gas generated by the combustible material. The carbonization chamber outer cover is installed on the top of the carbonization chamber, wherein the outer surface of the carbonization chamber outer cover has at least one hanging ring. The furnace cover is installed above the storage space to cover the top of the outer chamber (the furnace cover needs to be removed during combustion). The base is installed at the lower opening of the outer chamber to cover the bottom of the outer chamber. The inner chamber is located inside the outer chamber. The upper portion of the inner chamber is connected to a hot air pipe. An exhaust port of the hot air pipe is located outside the outer chamber and is covered by a lockable outer cover. Below the inner chamber is an ash collection area surrounded by multiple secondary air holes. An inner furnace door is also provided on the lower side of the inner chamber. A first grate plate is located inside the inner chamber. The upper portion of the first grate plate serves as a combustion zone. A second grate plate is located inside the inner chamber and below the first grate plate. An ash collection tray is disposed between the inner and outer chambers and below the bottom of the inner chamber. The ash collection tray is used to collect ash from the combustible material after combustion. Two guide ramps are disposed within the inner chamber and below the first grate plate. The two guide ramps are used to guide the ash from the combustible material after combustion to the ash collection area. A first outer furnace door is located above the exterior surface of the outer chamber and has a first outer door handle, wherein the outer door handle is used to close or open the first outer furnace door. A second outer furnace door is located above the outer surface of the outer shell and has a second outer door handle, wherein the second outer furnace door is closed or opened by the second outer door handle. The combustible material is placed in the combustion zone for combustion and is ignited manually or automatically. The combustible material is discharged through the second ventilation holes, and the ashes of the combustible material fall downward to the ash collection area and the ash collection tray.

In one embodiment of the present invention, the multifunctional environmentally friendly combustion furnace further includes a controller and an air supply fan. The controller is disposed outside the outer shell. The air supply fan is disposed outside the outer shell and includes a motor connected to the controller.

The following will further explain the operating mechanism of this multifunctional environmentally friendly combustion furnace 100.

Ignition and Startup: In preparation for combustion, combustible materials TA must be placed evenly and orderly in the designated combustion area FA above the first furnace plate 110A, according to a specific arrangement and quantity. This orderly placement ensures that the combustible materials have sufficient access to oxygen and burn evenly, avoiding localized overheating or incomplete combustion.

Users can choose the ignition method based on their specific usage scenario and personal preference. Manual ignition uses a common igniter, such as an electronic lighter, to ignite the placed combustible material TA. Automatic ignition, on the other hand, relies on an automatic ignition device pre-installed near the combustion area FA. This device typically consists of a sensor, a controller, and an ignition element. When the system detects that ignition conditions are met (such as combustible material being placed in place and the oxygen supply system being ready), the controller issues a command, causing the ignition element to instantly generate a high-temperature spark, automatically igniting the combustible material TA.

Oxygen supply and combustion support: The oxygen inlet blower 118 is mounted on the exterior of the outer chamber 101. Its core component, the motor 123, is tightly connected to the controller 113 via an electrical circuit. When the furnace is started, the operator sends a start command to the motor 123 via the controller 113. Upon receiving the command, the motor 123 begins to rotate at high speed, driving the blades inside the blower at a specific speed. The high-speed rotation of the blower blades creates a strong suction force, continuously drawing air from the outside into the fan. The air is initially filtered inside the fan to remove any dust and impurities it may contain, preventing these contaminants from entering the furnace and affecting combustion efficiency and equipment life. Purified air is delivered to the combustion zone FA within the bladder 104 in a stable and uniform flow through the first and second oxygen inlet pipes 108 and 109. Once sufficient oxygen enters the combustion zone FA, it quickly mixes and thoroughly interacts with the burning combustibles TA. As a key fuel in the combustion reaction, oxygen significantly accelerates the oxidation reaction rate of the combustibles TA, making the combustion more intense. This allows the combustibles TA to burn more fully and efficiently, releasing more energy and providing sufficient heat support for various subsequent applications.

Combustion Process: With a continuous supply of oxygen and an ignition source, the combustible material TA begins to burn vigorously in the combustion zone FA. Low-temperature gasification and high-temperature combustion occur. Harmful substances in the low-temperature combustible gases undergo secondary combustion at high temperatures, ranging from 800 to 1000 degrees Celsius, resulting in a smokeless and odorless atmosphere. Combustion is a complex chemical reaction. As combustion progresses, the chemical energy in the combustible material TA is gradually converted into heat energy. Simultaneously, a large amount of heat is released, and ash AS is the incombustible residue remaining after the combustible material has burned.

Smoke Treatment: Fume (FG) generated by combustion is first directed into carbonization chamber 105 due to the upward movement of the hot gas flow and its own diffusion. Carbonization chamber 105 is filled with a variety of materials with unique physical and chemical properties, such as activated carbon and catalysts. As the smoke (FG) flows through these materials, physical adsorption occurs first. Porous materials like activated carbon, with their large specific surface area, adsorb carbon particles and some organic compounds from the smoke, separating them from the smoke. Simultaneously, the catalyst triggers a series of chemical reactions. For example, the catalyst can promote an oxidation reaction between harmful volatile organic compounds and oxygen, converting them into harmless substances such as carbon dioxide and water, thereby reducing the harmful content in the smoke. After purification in the carbonization chamber 105, the smoke is discharged through the second air vents 104C evenly distributed around the inner bladder 104, entering the space between the inner and outer bladders. Finally, through low-temperature vaporization and high-temperature combustion, it achieves a smokeless and odorless effect.

Ash Collection: As combustion continues, the combustible material TA gradually burns out, and the resulting ash AS naturally falls downward under the influence of gravity. Because the first and second grating plates 110A, 110B, are provided with sized gaps or holes, the ash AS can pass through these gaps and move downward. Two guide ramps 111, positioned within the inner chamber 104 below the first grating plate 110A, are positioned at specific angles and positions to effectively guide the ash AS's path. The guide ramps 111 redirect the ash AS, gradually converging toward the ash collection area 104A. During this process, some ash AS falls directly to the ash collection tray 120 located below, between the inner and outer chambers 104, 101, due to gravity and inertia. Ash collected in the ash collection area 104A and the ash collection tray 120 can be regularly cleaned by opening the inner furnace door 104B and cleaning related parts, ensuring the cleanliness of the furnace interior and maintaining its normal operation.

Thermal Insulation: The first insulation wall 115, located between the inner and outer chambers 104 and 101, is constructed from high-temperature-resistant, low-thermal-conductivity insulation materials, such as ceramic fiber and rock wool. These materials offer excellent thermal insulation properties, effectively preventing the high heat generated by combustion within the inner chamber 104 from being transferred to the outer chamber 101. The second insulation wall 116, attached to the exterior of the outer chamber 101 and also constructed from high-performance insulation, further enhances the ability to prevent heat loss from the outer chamber. This double insulation structure creates a highly effective thermal barrier, significantly reducing heat loss from the furnace to the surrounding environment. This thermal insulation design not only ensures a high temperature environment inside the furnace, facilitating continuous combustion reactions and efficient heat utilization, but also prevents operators from accidentally burning themselves when near the furnace's hot exterior, thereby enhancing equipment safety. Furthermore, reduced heat loss means more heat is available for actual heating or processing, improving energy efficiency and reducing energy consumption, thus meeting energy conservation and environmental protection requirements.

This invention's ventilation mechanism not only creates more gaps between the combustibles accumulated within the combustion space, allowing air to more easily pass between them and increase combustion efficiency, but also, the operation of the air supply fan 118, which achieves low-temperature vaporization and high-temperature combustion, allows air to pass more efficiently between the combustibles through the air inlet holes, significantly increasing combustion efficiency. Notably, the air supply fan 118 can be adjusted via the power regulator 119 to achieve secondary combustion at temperatures between 800 and 1000 degrees Celsius, achieving smokeless and odorless combustion, thus improving combustion efficiency.

In summary, the multifunctional environmentally friendly gas stove disclosed in this invention can bring the following benefits:

1. Increase combustion efficiency; low-temperature gasification and high-temperature combustion. Low-temperature combustible gas harmful substances are pyrolyzed at high temperatures, with secondary combustion at temperatures of 800-1000 degrees Celsius, achieving smokeless and odorless combustion.

2. Automatically collects ash and improves air circulation.

3. Heat can be recovered and converted into heat energy for processing.
