Reason.The incinerator and quenching apparatus are arranged on same manometer tube, the manometer tube upper semisection be incineration area, the pressure
Pipe lower semisection is chilling area, and chilling area carries out quick refrigeration to less than 200 DEG C to the flue gas after burning, it is to avoid the product of two English
It is raw.Water washing device to tail gas in most acid ingredients carry out solution absorption, alkaline cleaner is further to the acid in tail gas
Property composition carries out synthesis, treats in tail gas only surplus carbon dioxide and vapor, enters air, complete the process of high-risk waste liquid.
Compared with prior art, the device of the present invention is based on using arc-plasma cracking technique, to residual liquid the present invention
Preheating system is cleverly arranged that waste liquid is preheated, and waste liquid temperature is constantly raised, and viscosity is reduced, flowing
Property is improved therewith, and after waste liquid reaches enough mobility, to next process, whole preheating process can pass through waste liquor stream
Automated condtrol, processes convenient, efficient energy-saving, it is ensured that what is cracked and burn is abundant, and hazardous waste disposal ability is strong,
Scope is wide, can complete nontoxic, the harmless treatment of nearly all type waste liquid, waste gas, can be towards chemical industry, medicine, pesticide, petrochemical industry
Deng numerous areas, it is to avoid secondary pollution is produced, while avoiding the generation of two English, result can reach the U.S., Japan, Europe
