Abstract

The invention provides a urea solution pyrolysis denitration spray gun, and belongs to the technical field of denitration equipment. The spray gun comprises a spray gun barrel, wherein a single-fluidnozzle is arranged on the left side of the spray gun barrel and an electric-heating tube is disposed inside the spray gun barrel; compared with a pyrolyzing furnace, the energy consumption is lower, the occupied space is smaller, the equipment investment is low; compared with the mode that ammonia water or ammonia gas is selected as a reducing agent, the problems of environmental pollution and fire safety caused by ammonia water or ammonia gas leakage are solved.

Description

technical field [0001] The invention relates to a urea solution pyrolysis denitration spray gun, which belongs to the technical field of denitration equipment. Background technique [0002] The existing products mainly use dual-fluid atomizing spray guns, which adopt rear-end mixing atomization and front-end atomization forming. The current structure is mainly suitable for use under the conditions of high denitrification temperature and compressed air source in the factory area. For small boilers, there will be problems such as low furnace tail temperature, urea cannot be pyrolyzed, and the choice of reducing agent is difficult. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a urea solution pyrolysis denitrification spray gun, which is used to solve the problems in the prior art that the tail temperature of small and medium-sized boilers is low, urea cannot be pyrolyzed, a...
