Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household garbage treatment, and is a household garbage wet distillation low-temperature pyrolysis tar separation and collection system. BACKGROUND

[0002] At present, the widely used household garbage treatment technology in China is landfill treatment, because the landfill treatment technology is simple in process, convenient in operation and least in investment. However, the landfill treatment has serious hazards, such as large land occupation area, serious leachate pollution, short service life, many safety hazards and unsuitable for popularization. Therefore, people hope to reduce garbage landfill through high-tech, high-quality and pollution-free incineration.

[0003] Pyrolysis treatment is a very effective resource treatment method, and the specific process is to heat solid waste to a certain temperature under oxygen-free or dilute oxygen conditions, and use heat to break the chemical bonds of compounds, so as to convert organic matter with large relative molecular mass into intermediate products of energy products, i.e. small relative molecular mass combustible gas, liquid fuel and coke. The pyrolysis process is an endothermic reaction, and the products are liquid tar, solid coke and fuel gas, etc. Some also call pyrolysis as "dry distillation". The advantage of garbage pyrolysis treatment is that the treatment period is short, the land occupation area is small, the maximum degree of volume reduction can be realized, the service life of the landfill site is prolonged, and the application range of waste is more extensive. Moreover, the organic components in the waste can be utilized while the volume is rapidly and significantly reduced.

[0004] The furnace body disclosed in the Chinese patent document with publication number CN111425861A and the name of a magnetized low-temperature pyrolysis furnace body for household garbage treatment cannot effectively treat garbage with kitchen soup and rain and snow garbage, and does not have a spraying device, so it cannot control open flames, the structure function is single, and there is no exhaust system, so it cannot treat the generated waste gas before discharging.

[0005] The patent document CN217131298U discloses a process for treating tail gas of the furnace body: after pyrolysis, the flue gas flows to the ion capture pipe bundle through the air distributor, the ion capture pipe bundle starts to work on the flue gas, the positive ions in the flue gas are adsorbed on the negative corona electrode, and the negative ions are adsorbed on the positive deposition electrode; all the positive and negative ions are filled in the entire space between the corona electrode and the deposition electrode, the impurities such as tar, droplets and the like in the flue gas entering the ion capture pipe bundle through the air distributor are adsorbed with negative ions and electrons, and then move to the deposition electrode under the action of the electric field force generated by the electric field generator, release the charges carried, and are adsorbed on the deposition electrode, so that the purpose of purifying the flue gas is achieved. When the impurities such as tar, droplets and dust adsorbed on the deposition electrode increase to be greater than the adhesion force, they will automatically flow downward and be discharged from the bottom of the ion capture pipe bundle into the furnace body of the magnetized low-temperature pyrolysis furnace. The purified flue gas is subjected to removal by a carbon monoxide removal device. The carbon monoxide in the flue gas is removed by catalytic oxidation method. The catalytic combustion oxidation is to heat the gas containing carbon monoxide to about 110 DEG C under oxygen condition to enter the catalytic reaction device. Under the action of the catalyst, the carbon monoxide and oxygen react to generate carbon dioxide, so that the purpose of removing carbon monoxide is achieved. However, the tail gas treatment process still has the disadvantages of complex structure, high failure rate in use and low tail gas treatment efficiency.

[0006] The patent document CN212068233U discloses a tail gas purification system for a low-temperature magnetized garbage decomposition device. The beneficial effects of the tail gas purification system are as follows: 1. The flue gas generated after incineration enters the flue gas filtration channel from the air inlet pipe, is filtered by the filtering device, enters the flue gas purification channel, and is then purified by the flue gas purification device before being discharged from the air outlet pipe. In this way, the flue gas is purified before being discharged into the atmosphere, which greatly reduces the pollution to the air environment; 2. The flue gas is cooled and filtered by the water curtain. The water curtain is a special paper honeycomb structure material, which absorbs the heat of the flue gas through water evaporation. At the same time, when the tail gas rich in water vapor, tar gas and dust passes through the cooling water curtain, the water vapor becomes condensed water, and the tar gas and dust are partially adhered to the cooling water curtain, thereby effectively purifying the flue gas. However, the tail gas treatment system cannot recover tar, and the treatment efficiency of raw materials is low.

[0007] The currently disclosed low-temperature pyrolysis processor cannot quantitatively control the low-temperature pyrolysis temperature, does not have a spraying device, relies on manual vibration or water spraying to control open fire, cannot effectively treat garbage with kitchen soup and rain and snow garbage, cannot effectively treat tail gas, cannot meet environmental protection requirements, and cannot be used for actual treatment of household garbage.

A padding layer 12 is filled in the filling cavity. At least two rings of magnetic boxes 9 are fixedly installed at intervals along the circumference of the inner side of the lower part of the furnace body 8 within the padding layer 12. Each magnetic box 9 contains a magnetic strip 13. Several ash removal ports, interconnected internally and externally, are distributed at intervals along the circumference of the lower part of the furnace body 8, corresponding to the position above the baffle 10. Each ash removal port contains an ash removal door 17. Several feed ports, interconnected internally and externally, are evenly distributed at intervals along the circumference of the upper outer side of the furnace body 8. Each feed inlet is equipped with a feed gate 14. Several side wall ventilation openings with internal and external connections are provided at intervals on the lower outer side of the furnace body 8 between each pair of adjacent feed inlets. A wind valve 15 is provided on the outer side of the furnace body 8 corresponding to each side wall ventilation opening.
