Problems solved by technology

However, at present, the tower top exhaust gas of most domestic manufacturers is directly discharged, which has caused serious pollution to the environment, and also caused loss and waste of raw materials
The reason why enterprises do not treat the exhaust gas at the top of the tower is because there is currently no effective and feasible treatment process

Abstract

The invention relates to a high-tower compound fertilizer granulation tower top tail gas purification equipment, which consists of a granulation tower body (1), a granulation tower equipment inner cylinder (3), a water collection circulation pool (4), and a water collection bucket ( 5), packing section (6), washing water spraying device (7) and axial flow induced draft fan (8). The invention effectively purifies the tower top tail gas produced in the production process of high-tower granulated compound fertilizer, and the purification rate of dust and ammonia nitrogen in the tail gas can reach more than 90%, effectively solving the problem of exhaust gas discharged in the production process of high-tower compound fertilizer. The pollution of the atmospheric environment plays a positive role in environmental protection and has huge social benefits.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of fertilizer production equipment. More specifically, the present invention relates to a high-tower compound fertilizer granulation tower top tail gas purification equipment. [0003] 【Background technique】 [0004] my country's compound (mixed) fertilizer industry has achieved considerable development in recent years, which has played a key role in modern agricultural production and my country's food security. As a new technology for the production of compound (mixed) fertilizers, the high-tower granulation compound fertilizer process has developed rapidly in recent years, and the products are well received by the market, and this development momentum is still in progress. According to incomplete statistics, there are more than 200 compound fertilizer granulation plants that have been built and operated nationwide, with a total production capacity of more than 40 million tons per year, and the num...
