Description

Technical Field

[0001] The invention relates to the technical field of tail gas treatment, in particular to tail gas treatment equipment of a compound fertilizer granulation tower. Background Art

[0002] Compound fertilizer refers to fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yield of crops. Common granulation processes for compound fertilizer include: drum granulation, disc granulation, spray granulation, high tower granulation, etc. Most of the tail gas in the granulation process is directly discharged, and the dust and its volatile matter enter the atmosphere directly with the exhaust air flow, causing waste of resources and environmental pollution, and unable to meet the increasingly high environmental protection requirements. In the tail gas emission, it is necessary to filter the dust and particulate matter in the tail gas.

[0003] When treating exhaust gas, the existing device cannot control the exhaust gas emission rate, cannot slow down the exhaust gas emission rate, and the small particles contained in the exhaust gas cannot be fully absorbed, resulting in poor adsorption and filtration effects.
