Definitions
- the invention presents equipment for laboratory that will produce biochar and synthesis gas from vegetable remains, the equipment being fitted with temperature and pressure control sensors that provide the information for a programmable controller that ensures the operation of the system.
- patent US 2013264831A1 which relates to a gasifier with controlled biochar removal mechanism including a biochar and electric power generator that receives material and outputs variable amounts of electrical energy and chat, including a pyrolysis module, a reaction module and a char removal mechanism arranged between the pyrolysis module and the reaction module, an engine module including an engine and an alternator, configured to convert the gaseous fuel produced by the reaction module into electric power and to provide waste heat to the pyrolysis module and a flare configured to burn tar gas and provide waste heat to the pyrolysis module.
- the feeding system is complex and consists of three augers for transporting raw material, it has a low degree of sealing and the biochar production process does not occur in an environment with low input or in the absence of oxygen; unloading the biochar from the retort into a container is done by means of an auger conveyor and it is necessary that the equipment is not used for a period of time until the biochar has completely cooled.
- Patent US 2014250784A1 is also known, which relates to a type of updraft gasifier that uses the heat from the gas rising from the combustion process to reduce, pyrolyze and dry the material for biochar production.
- the disadvantages of this system are the following: low degree of sealing against the atmosphere during the pyrolysis process; unloading the biochar from the retort into a container is done using a tray and the biochar comes into contact with the atmosphere during the cooling process.
- Patent CN 102936505A (B) is also known, which relates to biochar charring furnace for a laboratory with a technical solution that includes a feeding tank, a heating steel pipe, a resistance wire, a temperature sensor, a casing and a cover and is characterized in that the feeding tank is a hollow steel barrel structure with an open upper end and a closed bottom and the heating steel pipe has an open upper end and a closed lower end.
- the heating layer is a winding heating resistance wire with insulating porcelain beads.
- Patent US 2021222071A1 is also known, which relates to a pyrolysis system and enhanced pyrolysis gas production where dry biosolids were pyrolyzed with the introduction of biochar as a downstream catalyst.
- the hot pyrolysis vapours exited the main pyrolysis reactor, passed through the hot catalyst, and were then separated by condensation.
- the biochar was obtained in the main reactor and the bio-oil was collected in the condensers.
- Patent US 20080014132A1 is also known, which relates to a biomass gasifier.
- the invention presents a wall structure defining a gasification chamber that has a biomass inlet at an upper end thereof and a char outlet at a lower end, a generally U-shaped char tube which has two vertical limbs, the first limb is positioned to receive char from the gasification chamber and the second limb terminates upwardly at a level above the char outlet of the gasification chamber and is connected to a blower, for inducing a flow of gas through the gasification chamber.
- the disadvantage of the equipment is that the system for unloading the biochar from the auger retort - which forces the material up into a two-limb "U" shaped container - involves blocking it during operation and therefore stopping the work process and manual unclogging of the equipment.
- Patent CN 215103026U is also known, which relates to a small mobile carbonization furnace for the production of biochar and fuel gas.
- the small carbonization furnace used to produce biochar and fuel gas comprises the furnace shell, a partition plate, a combustion chamber, a carbonization chamber, a waste gas treatment mechanism, a sealing mechanism, a cleaning mechanism, and a traction mechanism.
- the partition plate is fixedly installed in the furnace shell, the combustion chamber and the carbonization chamber are divided by the partition plate, the waste gas treatment mechanism comprises a waste gas treatment device, a first pipe, a cooler and a second pipe, the waste gas treatment device is arranged on one side of the furnace body, the first pipe is fixedly installed at the top of the furnace body, and the cooler is fixedly installed at the bottom of the furnace body.
- the system presents the use of synthesis gas for heating the retort in which the material for the production of biochar is burned, but this synthesis gas is mixed with steam and smoke resulting from the technological process and therefore the combustion efficiency is very low; an additional amount of time is required to cool down the equipment and then unload the biochar.
- Patent CN 218002214U is also known, which relates to a biochar carbonisation furnace under laboratory conditions.
- this carbonisation furnace has no cooling structure and depends only on free cooling in the atmosphere, which takes a long time and will lead to waste of heat. After carbonization is completed, due to the biochar in the furnace, the temperature is still high when it is directly opened, and it is easy to cause combustion when it comes into contact with oxygen, so it is necessary to cool the biochar.
- Patent US 6790317 is also known, which relates to a carbonization process to produce biochar from sawdust or wood waste and which uses a small amount of material as tinder or fuel to ignite the material in the retort.
- the disadvantages of this invention consist of the following: the long duration of time for the complete combustion of the raw material and then the unloading of the biochar; heavy working system involving physical effort when unloading; there isn't an active control of the working parameters during the technological process.
- the technical problem that the invention solves consists in the design of laboratory equipment that allows the establishment of optimal values for the production of biochar from various vegetable remains recipes, equipment fitted with command and control elements that use a programmable controller for the automatic control of the system.
- the equipment for biochar production from vegetable remains eliminates the disadvantages of the known solutions in that it consists of a mobile support provided with some swivel wheels for movement, the mobile support has two side walls on which are mounted two bearing housings that support an octagonal casing with the elements of actuation and control of important parameters for the production of biochar from vegetable remains.
- the octagonal casing is made of two octagonal tubs of stainless steel material class 316 (1.4401) which is the most suitable for polluted, industrial environments due to the fact that it has a higher corrosion resistance.
- the two octagonal enclosures are mounted concentrically and are insulated from each other with a very high temperature resistant ceramic fibre layer to eliminate heat loss from inside the equipment.
- the octagonal casing has two side bolts mounted in the two bearing housings on the support and will allow the equipment to be rotated from the vertical position to the inclined position at about 135° for unloading the material obtained by pyrolysis, the rotation of the equipment being done using a handwheel.
- an electrical resistance mounted for igniting the solid fuel.
- a fan or compressor can be used which sends the necessary air to a hole diffuser mounted near the electrical resistance. The air sent by this fan will hasten the ignition of the material in the vicinity of the electrical resistance.
- a double-walled, ceramic fibre-insulated metal top cover is mounted on the octagonal casing, the cover rotates by means of a hinge and is held in place by fixing screws. The cover will support a pressure relief valve, a high temperature thermocouple and a pressure sensor. Also in the cover is mounted a metal nipple that will allow coupling to a fan for high temperatures by means of a flexible metal hose. This fan can provide the draft necessary to ignite the entire amount of material, but it can also absorb the smoke together with the vapours produced at the beginning of the pyrolysis process and send them to the atmosphere.
- the electrical resistance for igniting the fuel is turned off.
- the material is ignited throughout the mass, which is dried in the first stage, and to continue the technological process, it is necessary to hermetically close the air hole at the bottom of the of the casing and the electromagnetic valve connected with the flexible hose and which is mounted on the octagonal casing cover. Due to combustion in a hermetically insulated space, the oxygen content inside the enclosure drops from 21% to approximately 2%, the pressure in the enclosure will increase to 10 bars and the temperature achieved is 400-500°C, depending on the biomass used and the air intake.
- the work cycle can be repeated by changing the working parameters: air pressure added to the combustion process and working temperature.
- a synthesis gas is obtained, which can be transported with the help of the high temperature fan connected to the upper cover of the enclosure. This gas can be cooled and separated from the liquid part and then stored in a gas cylinder, to be burned in a gas burner mounted on other pyrolysis equipment.
- the raw material is chopped to similar sizes, does not require prior drying and allows moisture of approx. 15-30%.
- the technological process takes about 40-60 minutes, depending on the moisture of the materials used in the production of biochar.
- Control of working parameters the pressure and temperature inside the retort can be controlled with the help of an electronic command and control panel, which can be equipped with a programmable controller for automatic control and adjustment of working parameters.
