Method and equipment for low-temperature magnetization treatment of garbage

Abstract

The invention relates to a thermal decomposition method and equipment for organic garbage, in particular to a method and equipment for low-temperature magnetization treatment of garbage. Firstly, low-temperature magnetized pyrolysis treatment is conducted on garbage raw materials, ash generated by pyrolysis is discharged out of a pyrolyzing furnace by using a discharging machine, and gas generatedby pyrolysis is introduced into a fixed bed for catalytic reaction, hydrocarbons, nitric oxides and carbon monoxide carried in a gas product are converted into harmless water, carbon dioxide and nitrogen, the purified gas is conveyed into gas collection and treatment equipment to be condensed, collected and subjected to tail gas purification treatment to become standard gas, and the standard gasis exhausted into the atmosphere through an induced draft fan. The invention discloses equipment for implementing the method.

Description

technical field [0001] The invention relates to a thermal decomposition method and equipment for organic waste, and belongs to the field of environmental protection technical equipment. Background technique [0002] With the continuous improvement of people's living standards, the amount of domestic waste, kitchen waste, industrial organic waste, agricultural and forestry organic waste, and medical waste continues to rise. Organic waste (such as waste plastic, waste rubber, paper scraps, wood, cloth, roots, Leaves, grass, leftovers after meals, medical waste, etc.) are prone to produce incompletely decomposed high-molecular heavy hydrocarbons and nitrogen oxides (NO X ) and carbon monoxide (CO), resulting in a considerable amount of hydrocarbons, nitrogen oxides, and carbon monoxide that pollute the atmosphere in the exhausted flue gas or pyrolysis gas; when tar or heavy oil is severe, gas pipes and valves are blocked, and excessive In CN 209672341 U "Low Temperature Magnet...

Problems solved by technology

[0002] With the continuous improvement of people's living standards, the amount of domestic waste, kitchen waste, industrial organic waste, agricultural and forestry organic waste, and medical waste continues to rise. Organic waste (such as waste plastic, waste rubber, paper scraps, wood, cloth, roots, Leaves, grass, leftovers after meals, medical waste, etc.) are prone to produce incompletely decomposed high-molecular heavy hydrocarbons and nitrogen oxides (NO X ) and carbon monoxide (CO), resulting in a considerable amount of hydrocarbons, nitrogen oxides, and carbon monoxide that pollute the atmosphere in the exhausted flue gas or pyrolysis gas; when tar or heavy oil is severe, gas pipes and valves are blocked, and excessive In CN 209672341 U "Low Temperature Magnetization Cracking Equipment for Organic Garbage" and CN 210230977 U "A Medical Magnetized Garbage Disposal Device", it is disclosed that organic waste can be processed in 350 Combustion at low temperature below ℃ and magnetized air, but no harmless treatment of light hydrocarbons (CH), heavy oil, tar, nitrogen oxides (NO, NO2) and carbon monoxide (CO) contained in the flue gas The air contains 21% oxygen by volume. Oxygen belongs to a paramagnetic substance with strong magnetic susceptibility. Under the action of an external magnetic field, the magnetic moment of oxygen molecules will change with the action of the external magnetic field. Indirect magnetization, the activation energy of oxygen in the magnetized air is greatly improved, reducing the energy required for pyrolysis of garbage, and a relatively small amount of air and lower temperature can maintain a more thorough combustion effect; however, low temperature magnetization pyrolysis The waste combustion of the furnace is an oxygen-deficient combustion process. The waste combustion with insufficient oxygen will cause the exhausted flue gas to contain a large amount of light hydrocarbons (CH), nitrogen oxides (NO, NO2) and carbon monoxide (CO) to pollute the atmospheric environment;
