Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to a low-temperature catalytic reaction device for exhaust gas treatment equipment. Background Technology

[0002] A cremator is a device used to cremate remains; it is a type of incinerator. Since most crematoriums now use diesel fuel as auxiliary fuel, they are collectively referred to as oil-fired crematoriums. During operation, the cremator produces exhaust gases including fumes, combustion gases, and foul odors. These gases contain large amounts of harmful substances such as carbon dioxide, carbon monoxide, hydrogen, hydrogen sulfide, and nitrogen. These harmful substances have adverse effects on the environment and human health, therefore, the exhaust gases from crematoriums need to be treated. Current technology primarily uses chemical absorption and physical adsorption to adsorb and decompose harmful substances in the exhaust gases, achieving air purification. Physical adsorption mainly utilizes activated carbon, which effectively adsorbs harmful substances in the cremator exhaust gases. To ensure treatment effectiveness, the activated carbon needs to be replaced regularly. However, in some treatment devices, the contact position between the activated carbon and the exhaust gas is fixed. When the adsorption efficiency of the adsorption components begins to decrease, some activated carbon is not effectively utilized, leading to waste and increasing the cost of cremator exhaust gas treatment.
