Description

 Multi-fluid cleaning method

 The present invention relates to a general method for cleaning a plurality of objects to be cleaned, and more particularly to a multi-fluid cleaning method for cleaning an object to be cleaned by using a plurality of fluids. Background technique

 Depending on the object to be cleaned and the cleaning requirements, cleaning is usually divided into three types: civil cleaning, industrial cleaning, and special cleaning. Regardless of the type of cleaning, the cleaning methods currently used are basically based on the theory of "dissolution", which is based on chemical dissolution and mechanical physical friction. Usually the solvent is first dissolved by the solvent, and then the mechanical energy is used to remove the dirt. At present, water is the most commonly used solvent, but the surface tension of water is relatively large. It is usually necessary to add a surfactant to reduce the surface tension of water and enhance the cleaning effect; while mechanical physical friction can remove the dissolved stains, but The cleaning tool must be in direct contact with the outer surface of the object to be cleaned, which will damage the surface of the object to be cleaned. If mechanical and mechanical friction is not used for non-contact cleaning, only solvent and high-pressure water are used. For stubborn adhesion stains, the effect is poor and the cleaning requirements are not met. The main problems in the traditional cleaning method are (1) a large amount of water consumption; (2) the use of cleaning agents to cause secondary pollution; (3) easy damage to the surface of the object to be cleaned.

 Therefore, a new cleaning method is needed, which can save a lot of water; no cleaning agent is used; no object to be cleaned is damaged; and environmentally clean cleaning is realized in a true sense. Summary of the invention

 The cleaning method of the present invention is based on the energy carried by the finely-enhanced water particles, acts on the "energy mass" of the dirt, and effectively "peeles" the stain, peels off the dirt from the object to be cleaned, and then at high Under the action of "flushing" and "shock" with multiple fluids, it can quickly "evaporate" to achieve the purpose of cleaning.

 According to the present invention, there is provided a multi-fluid cleaning method comprising the steps of:

 (1) energizing water by an energizing device and atomizing to form high-energy atomized water;

(2) The high-energy atomized water produced by the pipeline is supplied to the multi-fluid nozzle, and is sprayed to be cleaned. On the surface of the object, the object to be cleaned is firstly stained and peeled off with high-energy atomized water;

(3) After the peeling cleaning is completed, the high-energy atomizing water switch is turned off;

 (4) generating high-pressure gas from a high-pressure gas generating source, which is supplied from the pipeline to the multi-fluid nozzle; the liquid water is supplied from the pipeline to the multi-fluid nozzle;

 (5) Opening the high-pressure gas switch and the liquid water switch, mixing at the multi-fluid nozzle, forming a mixed fluid composed of a high-pressure gas and a mist of fine particles, rinsing the object to be washed, and rinsing the adhered stain on the surface of the object to be cleaned Leave

 (6) Turn off all switches to complete the cleaning process.

 Wherein, the liquid water in the step (4) is preferably liquid water energized by an energizing device. However, it can also be ordinary water, but the water consumption is large and the cleaning effect is poor.

 Wherein, before step (6), the method preferably comprises the steps of: closing the liquid water switch, and continuing to separately impact, evaporate and dry the object to be cleaned by the high pressure gas.

 Preferably, before step (6), the method further comprises the steps of: surface protecting the liquid, supplying the pipeline to the multi-fluid nozzle, opening the multi-fluid nozzle switch, mixing with the high-pressure gas at the multi-fluid nozzle, forming an atomizing fluid, uniformly spraying to The surface of the object to be cleaned forms a protective film.

 According to the present invention, the energization of water can be achieved by one or a combination of superheat energy, chemical energy, electrolysis, mechanical vibration, ionization, and ultrasonic waves depending on environmental conditions and the object to be cleaned. Empowering water simply changes the state and character of the water. After use, the energy is released, and the original state of the water can be restored in a short time without generating new chemicals and forming new pollution.

 One or more electromagnetic control valves are respectively disposed on the high-energy atomizing water pipe and each fluid pipe to control the energy intensity and flow rate of the high-energy atomized water and each fluid.

 The highly energized atomized water and the other fluid may use the same multi-fluid nozzle or different nozzles; different channels are provided on the nozzles to provide different fluid combinations as desired.

A sensor capable of accurately measuring the distance between the nozzle and the surface of the object to be cleaned is also provided on the nozzle. The sensor is also connected to a control device or display device, and the control device issues an instruction to the actuator whether to perform automatic position adjustment or whether the eye position is manually adjusted by the human eye through the display device. + The high-energy atomizing water pipeline and each fluid pipeline are also provided with a pressure reducing valve and an adjustable flow, and the high-energy atomizing water pipe is made of a high temperature resistant and high pressure resistant material.

 The combination of high-energy atomized water, energized water and high-pressure gas into a "multi-fluid" can achieve different functions such as "peeling", "flushing,", "evaporation," and so on. No contact cleaning. The higher the energy of the atomized water, the smaller the particle size, the better the volatility and the stronger the peeling ability. For different cleaning objects, the energy should be limited to the safe range, and the working distance can be precisely controlled. If the energy is too large, the object to be cleaned may be damaged. After the stripping process is completed, only a small amount of peeled stain remains on the surface of the object to be cleaned, and the object to be cleaned is rinsed with a combination of a lower energy and a larger particle size.

 The invention differs from the traditional cleaning theory by relying on the "dissolution" of chemical energy, but mainly relies on physical energy to "break up" the "energy mass" of the dirt, by "peeling away", "rinsing", "shocking" and "evaporating" "The process of cleaning the dirt off. The method has short cleaning time and strong decontamination ability, and can remove almost all stubborn dirt, and the cleaning effect is obviously superior to the traditional cleaning method. However, the water consumption is small, about 5% of the traditional cleaning, further optimized, or even less; no cleaning agent is used, no secondary pollution to the environment; no contact with the object to be cleaned except the fluid, no Damage to the surface of the object being cleaned. The invention almost solves all the problems existing in the conventional cleaning, and realizes the environmental protection in the true sense. DRAWINGS

 Specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. among them:

 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a multi-fluid cleaning process of the present invention. detailed description

 In Fig. 1, the following main devices of the cleaning method of the present invention are mainly shown:

 High-energy atomizing water generator 1, high-energy atomizing water pipeline 2, multi-fluid nozzle 3, air pump 4, gas pipe 5, energizing water (or ordinary water) container 6, water pipe 7, electromagnetic control valve 8 - 10 Composition

In the present invention, highly energized atomized water is used as the main cleaning medium. First through high The atomizing water generator 1 produces highly energized atomized water. The water-enhancing energy can be realized by various means such as heat energy, chemical energy, electrolysis, mechanical vibration, ultrasonic wave, etc., which is a conventional technique and will not be described herein. The resulting highly energized atomized water is passed through a highly energized atomized water line 2 and passed to at least one multi-fluid nozzle 3. Among them, the high-energy atomizing water pipeline is preferably made of high temperature resistant and high pressure resistant materials; conventional pressure resistant materials can also be used as long as the energy transfer requirements can be met. In addition, one or more electromagnetic control valves 1 - 4 are provided at appropriate locations of the line 2 for controlling the energy parameters of the highly energized atomized water. The number of the nozzles 3 depends on the size and size of the object to be cleaned, and may be one or plural. The nozzles can be manually clamped or clamped by an automatic device, such as an automatically controlled walking trolley, or a computer controlled robot.

 Through the above nozzle 3, the highly energized atomized water peels off the stubborn stain attached to the surface of the object by the energy carried and the properties of the very fine state. The higher the energy of the atomized water, the smaller the particle size, and the volatilization thereof The better the sex, the stronger the peeling ability. However, the energy of the atomized water should be set for the specific object to be cleaned, otherwise the process and cost requirements will increase accordingly. For different cleaning objects, the energy of the highly energized atomized water can be limited to a safe range by modulating the electromagnetic control valve 8. In addition, a distance sensor (not shown) capable of accurately measuring the distance between the nozzle and the surface of the object to be cleaned can be provided on the nozzle 3 to precisely control the working distance, because in some cases (for example, the object to be cleaned is relatively precise), energy Excessive size may damage the object being cleaned. The distance information of the sensor can be sent to the automatic control device, or can be transmitted to the discriminating circuit of the cartridge. According to the preset range of values, it is judged whether the distance is appropriate, and the nozzle is directly controlled by the automatic control device or the sound and light signal is indicated by the discriminating circuit. Manual operator adjustment.

 After the high-energy atomized water stripping cleaning is completed, the atomizing water line 2 is turned off. Then open the high pressure gas and the energized water (or normal water) lines. In the present invention, the high pressure gas is produced by an air pump 4, and of course, high pressure gas can be generated by other known means. The high pressure gas generated by the air pump 4 is sent to the nozzle 3 through a high pressure gas pipe 5. A solenoid valve 9 for controlling the pressure of the high pressure body can be provided on the gas pipe 5. At the same time, the liquid water supplied from the energized water (or ordinary water) vessel 6 is also sent to the nozzle 3 through the water pipe 7, and the liquid pipe solenoid valve 10 for controlling the water flow can also be provided on the water pipe.

At the nozzle 3, the high-pressure gas generated by the air pump 5 and the capacity of the energized water (or ordinary water) The liquid water provided by the device 6 is mixed to form a mixed fluid composed of a high-pressure gas and a fine particle water mist, and the object to be cleaned is washed, and the stain adhered to the surface of the object to be cleaned after being stripped by the high-energy atomized water is washed. Drop it. Due to the action of the high pressure gas, a part of the evaporation can also be performed. Since the water and gas fluids have separate circuits and control valves, they can be scaled for different objects to be saved, saving energy and water. Since the dirt and stains are attached to the surface of the cleaning object during the peeling and cleaning, only 4 times of high-pressure water is needed in the high-pressure washing to easily remove the adhered stains, thereby achieving the purpose of greatly saving water.

 After the high-pressure water and gas mixed fluid is flushed, the water circuit is closed, and only the high-pressure gas alone impacts the object to be cleaned, further impacts, evaporates, and dries, and the cleaning process is completed.

 In addition, the multi-fluid nozzle is provided with a plurality of pipe joints, which can be conveniently connected to other fluids, and can include further processing of the object to be cleaned after completion of cleaning and drying, such as waxing, or spraying protective materials. and many more.

 The entire cleaning process can be manual or controlled by a computer for automatic cleaning.

 In a preferred embodiment of the present invention, all fluids may be uniformly sprayed through a multi-fluid nozzle, or the high-energy atomized water nozzles may be separately disposed from other fluids, and a plurality of channels may be disposed according to different needs, respectively or Mixing and spraying different fluids improves cleaning efficiency.

 According to the present invention, the inherent defects of the conventional cleaning method are better solved, and a large amount of water is saved, which is only about 5% of the water consumption of the conventional cleaning method; and since the chemical cleaning agent is not required, the environment is not polluted; The object to be cleaned is not in direct contact and will not damage the surface of the object to be cleaned and the decorative layer. The cleaning method of the invention has short cleaning time, strong detergency, and the cleaning effect is obviously superior to the conventional cleaning method.

 The invention can be used in a variety of applications and can replace traditional water cleaning, including but not limited to:

 - 1. Vehicle cleaning, including: cleaning of vehicles, airplanes, ships, trains, etc., can be made into automatic washing machines, aircraft washing machines and other devices;
