The integrated tail gas treatment equipment can be matched with various types of cremation machines. The dust collector integrates a high-efficiency cooling reactor, an output rate interceptor, a bag filter, and a heavy metal dioxin adsorption device. It can be customized according to the size of the funeral home workshop. There are installation arrangements. The use of cooling, dust removal, desulfurization and other facilities can remove pollutants in the flue gas, quickly reduce the flue gas temperature to below 180 degrees in a short period of time (the cooling temperature is controllable), skip the temperature control area where dioxins are easy to form, and achieve national environmental protection emissions standard.
