Modular dust removal and denitration integrated apparatus

Abstract

The invention discloses a modular dust removal and denitration integrated apparatus. The apparatus comprises a denitration system and a dust removal system which are respectively arranged at the upperpart and the lower part of the same chamber of a tank body and are separated by a heat exchanger in the middle, the dust removal system is connected with an air inlet channel, and the denitration system is connected with an air outlet channel; the dust removal system comprises a dust removal bucket, a dust remover and a blowing device, and the air inlet channel is connected to the chamber where the dust remover is located; the denitration system comprises a reducing agent injection device, a rectification grid and a catalyst device, and the air outlet channel is arranged at the top end of thedenitration chamber; and a bypass flue gas channel is arranged between the air inlet channel and the air outlet channel and is arranged outside the tank body. The dust removal system and the denitration system are vertically arranged in the same tank body, so that cooperative treatment of dust removal and denitration is realized, and the occupied space of the apparatus is reduced; and the catalyst device is arranged in a modular mode, so the catalyst device and the dust remover with the same area have the same flue gas treatment capacity and can be flexibly arranged to meet different requirements.

Description

technical field [0001] The invention relates to the technical field of air pollution control, in particular to a modular dust removal and denitrification integrated device. Background technique [0002] Nowadays, the requirements for waste gas treatment are becoming more and more stringent, and the waste gas emissions from heavily polluting industries need to be strictly treated before being discharged. Enterprises that need to carry out tail gas treatment have installed denitrification and dust removal equipment, but the total amount of waste gas in non-electric fields is small. The use of a complete set of split-type out-of-stock dust removal equipment not only occupies a large area, but also requires high equipment construction costs, and the efficiency of the equipment after completion cannot be fully utilized, resulting in waste of resources. Moreover, the flue gas temperature is generally between 180-280 °C, and it is difficult to select catalysts and dust removal equi...

[0002] Nowadays, the requirements for waste gas treatment are becoming more and more stringent, and the waste gas emissions from heavily polluting industries need to be strictly treated before being discharged. Enterprises that need to carry out tail gas treatment have installed denitrification and dust removal equipment, but the total amount of waste gas in non-electric fields is small. The use of a complete set of split-type out-of-stock dust removal equipment not only occupies a large area, but also requires high equipment construction costs, and the efficiency of the equipment after completion cannot be fully utilized, resulting in waste of resources

Moreover, the temperature of the flue gas is generally between 180-280 °C, and it is difficult to select catalysts and dust removal equipment, resulting in poor exhaust gas treatment effect and failure to fully meet the standards. It is necessary to add auxiliary equipment to fully meet the emission standards, which in turn leads to an increase in equipment costs.
