Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas purification equipment, specifically an exhaust gas purification device for municipal solid waste incineration. Background Technology

[0002] Household waste refers to solid waste generated by people in their daily lives or in activities that provide services for daily life, as well as solid waste that is considered household waste according to laws and administrative regulations. It mainly includes residential waste, market and commercial waste, public place waste, street cleaning waste, and waste from enterprises and institutions. The incineration of household waste will produce a large amount of exhaust gas, which will cause environmental pollution if directly emitted. Therefore, exhaust gas purification equipment is needed to purify the exhaust gas from the incineration of household waste.

[0003] Chinese patent discloses a municipal solid waste incineration flue gas purification device (authorization announcement number CN214715643U). This patented technology for municipal solid waste incineration flue gas purification device is easy to operate and has high purification efficiency.
