A bag filter type deep denitrification and dust removal integrated system

Abstract

The invention discloses a bag filter type deep denitration and dedusting integrated system. The bag filter type deep denitration and dedusting integrated system comprises a denitration and dedusting integrated equipment body, an ammonia and flue gas distribution module, an ammonia distribution module and an ammonia preparation system connected with the ammonia distribution module. Denitration and dedusting integration is realized, the area occupied by the equipment is reduced, and the denitration and dedusting integrated system has better application prospect in small and medium boiler projects. A flue gas and ammonia water mixture is uniformly distributed after passing through a dust layer on the outer surface of a filter bag, and maximized utilization rate of a catalyst is realized. The catalyst is maintained and replaced more easily through arrangement of separate bins of a deduster. Dedusting is realized before denitration, so that the problems of blockage and poisoning of the denitration catalyst and the like are solved. The system can adapt to boiler load and coal quality change by means of a secondary distribution pipeline.

Description

technical field [0001] The invention relates to the field of boiler flue gas purification, in particular to a bag filter type deep denitrification and dust removal integrated system. Background technique [0002] The traditional boiler flue gas purification system has a large volume and needs to occupy a very large space. It is often limited by the site problem, which makes it difficult to implement in small and medium-sized places. However, the miniaturized purification system cannot fully utilize the catalyst effectively, resulting in waste. Furthermore, due to The equipment is too large and certain components are not easily accessible. Contents of the invention [0003] The purpose of the present invention is to provide a bag filter type deep denitrification and dust removal integrated system. [0004] According to one aspect of the present invention, a bag filter type deep denitrification and dust removal integrated system is provided, comprising: a denitrification an...
