Waste incineration exhaust gas deacidification treatment system

Abstract

The invention discloses a waste incineration exhaust gas deacidification treatment system. The waste incineration exhaust gas deacidification treatment system structurally comprises waste incinerationequipment, an incineration exhaust gas pipeline, a smoke pipeline, a water supply pipe, a smoke discharge pipe, a circulating water tank, a high-pressure water pump, a smoke purifier and a deacidification water mist spraying tower, and the waste incineration equipment is connected with the deacidification water mist spraying tower through the incineration exhaust gas pipeline. Compared with the prior art, the waste incineration exhaust gas deacidification treatment system has the beneficial effects that through combination arrangement of parts such as a tilting nozzle, a top arc plate, an exterior plate, an inner supporting plate, a bottom arc plate and a separation arc plate, a novel spraying pipe is constituted, a function of preventing blocking of particulate matter is achieved, the particulate matter can be effectively prevented from making contact with a spray head, the spray area can further be enlarged, thus all exhaust gas can be subjected to spraying deacidification, and thusspraying deacidification is more comprehensive, higher in efficiency and better in effect; and meanwhile, the spray head can be prevented from being blocked by the particulate matter, thus the deacidified gas can be normal discharged, and the efficiency of waste incineration treatment is advantageously improved.

Description

technical field [0001] The invention relates to the technical field of garbage incineration waste gas treatment, in particular to a garbage incineration waste gas deacidification treatment system. Background technique [0002] In the process of urbanization, garbage, as a product of urban metabolism, used to be a burden on urban development. Many cities in the world have been surrounded by garbage. Today, garbage is considered to be the most potential and inexhaustible "urban mineral deposit" and a "misplaced resource". The heat output from incineration can be collected and utilized through garbage incineration and converted into electricity. [0003] Waste incineration exhaust gas contains acid gases, including hydrogen chloride, sulfur dioxide, nitrogen oxides, etc. If these substances are discharged directly without treatment, they will cause great harm to the atmosphere. Waste incineration exhaust gas needs to be deacidified, and atomization is generally used The spraye...

Problems solved by technology

[0003] Waste incineration exhaust gas contains acid gases, including hydrogen chloride, sulfur dioxide, nitrogen oxides, etc. If these substances are discharged directly without treatment, they will cause great harm to the atmosphere. Waste incineration exhaust gas needs to be deacidified, and atomization is generally used The sprayed lye reacts with the acid gas to achieve the purpose of deacidification of the waste gas. In the deacidification process of the existing atomization sprayer, the spray port is facing the waste gas, so the particulate matter collected by the incineration waste gas is very easy Attached to the sprinkler, which will cause the sprinkler to be blocked, which will affect the discharge of deacidification gas
