High-temperature denitration and dust removal integration equipment

Abstract

The invention provides high-temperature denitration and dust removal integration equipment. The high-temperature denitration and dust removal integration equipment comprises a body and an ash bucket,wherein the body is of a V-shaped plate-type structure; the body is arranged in a flue or a reactor and is used for carrying out out denitration and dust removal on flowing-through flue gas; and the ash bucket is arranged outside the flue or the reactor, is located under the body and is used for collecting dust removed by the body. According to the high-temperature denitration and dust removal integration equipment provided by the embodiment of the invention, the V-shaped plate-type body is arranged in the flue or the reactor to remove the dust in the flue or the reactor and is used for cooperatively removing nitrogen oxide; the ash bucket for collecting the dust is arranged under the body; the high-temperature denitration and dust removal integration equipment has small pressure loss andsmall influences on the flowing of the flue gas, and can be used for effectively removing the nitrogen oxide in fly ash and the flue gas at high temperature, so that the abrasion to a catalyst and theblocking to subsequent equipment, which are caused by the fly ash in an SCR (Selective Catalytic Reduction) system can be effectively reduced and the total denitration efficiency of an SCR denitration system is improved.

Description

technical field [0001] The invention relates to the field of flue gas purification, and more specifically, to a high-temperature denitrification and dust removal integrated equipment. Background technique [0002] With the introduction of the national coal-fired ultra-low emission policy, it is difficult for the existing desulfurization and dust removal technologies to meet the strict emission targets under the ultra-low emission requirements. [0003] In the flue gas denitration system of SCR selective catalytic reduction technology in the prior art, high-temperature dust removal is mainly based on inertia and gravity deposition, but this kind of high-temperature dust removal device does not have simultaneous denitrification effect, which increases the flue resistance and affects the stability of flue gas flow Sexuality, increase the cost of denitrification system operation, due to the high flue gas flow rate in the actual use process, the dust removal effect is limited.

[0002] With the introduction of the national coal-fired ultra-low emission policy, it is difficult for the existing desulfurization and dust removal technologies to meet the strict emission indicators under the ultra-low emission requirements.

[0003] In the flue gas denitration system of SCR selective catalytic reduction technology in the prior art, high-temperature dust removal is mainly based on inertia and gravity deposition, but this kind of high-temperature dust removal device does not have simultaneous denitrification effect, which increases the flue resistance and affects the stability of flue gas flow Sexuality, increase the cost of denitrification system operation, due to the high flue gas flow rate in the actual use process, the dust removal effect is limited
