Bag type dedusting, desulfurization and denitrification process

Abstract

The invention relates to the technical field of bag-type dust collectors, and discloses a bag-type dedusting, desulfurization and denitrification process. A first support frame is included, a bag-type dust collector is fixedly mounted at the top of the first support frame, a smoke conveying pipe is arranged at one side of the top of the bag-type dust collector , and a buffer composite box is fixedly mounted at one end of the smoke conveying pipe. According to the desulfurization and denitrification bag type dust collector and the operation method thereof, a transmission shaft, the buffer composite box and a speed reduction purification mechanism are connected and matched to passively receive the impact force of flue gas entering the buffer composite box, and rotary force unloading is carried out by utilizing the structural characteristics of the bag type dust collector itself, the impact speed of flue gas about to enter the bag type dust collector body is reduced, meanwhile, the use effect of long service life of the bag type dust collector is maintained, then hard particles are continuously prevented from impacting a filter bag in the bag type dust collector body at a high speed for a long time, the filter bag is protected against damage, and the service life of the filter bag is ensured, and finally, the use cost of the whole equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of bag type dust collectors, in particular to a bag type dust removal desulfurization and denitrification process. Background technique [0002] The bag filter is a dry dust filter device that uses a bag-shaped filter element made of fiber fabric to capture solid particles in dusty gas. It is suitable for capturing fine, dry, non-fibrous dust. The device consists of an upper box Body, middle box, lower box, dust removal system and ash discharge system and other structures, its working principle is: filter dust removal device includes bag filter and particle layer dust collector, the former usually uses organic fiber or inorganic fiber fabric The filter bag made is used as the filter layer, and the filter layer of the latter is mostly composed of particles of different particle sizes, such as quartz sand, river sand, ceramsite, slag, etc., and the powder is repeatedly attached to the outer surface of the filt...

Problems solved by technology

[0003] At present, the bag filter is widely used in the flue gas treatment of desulfurization and denitrification, which greatly improves the environmental protection ability of the enterprise, but the existing bag filter still exposes some problems in the actual use process that need to be optimized and solved , mainly because the wind speed of the exhaust gas entering the ash hopper is relatively large and the air inlet is small, and the exhaust gas contains hard particles with edges and corners. cause damage, reduce the service life of the filter bag, and increase the use cost of the overall equipment. Aiming at the above problems, the present invention provides a desulfurization and denitrification bag filter and a desulfurization and denitrification process
