Desulfurization and denitration device by using screened-airflow shock wave suspension

Abstract

The invention discloses a desulfurization and denitration device by using a screened-airflow shock wave suspension. The device comprises a container body, the upper part of the container body is provided with a gas outlet, and the lower part of the container body is provided with a gas inlet. The device is characterized in that, the interior of the container body is provided with two or more stages of desulfurization and denitration units, the container body is disposed on a support, the desulfurization and the denitration units are successively disposed in the interior of the container body, and each desulfurization and denitration unit comprises a liquid-collecting board and an airflow distribution net. The desulfurization and denitration device by using the screened-airflow shock wave suspension has the advantages of saving energy and protecting environment, the technological process is short, the land occupation area is small, the industrial automation is easy to realize, the production is safe, and production costs are greatly saved.

Description

Technical field [0001] The invention relates to the technical field of desulfurization and denitrification, and more specifically, to a desulfurization and denitrification device for screening air shock wave suspension. Background technique [0002] With the development of my country's economy, environmental pollution caused by a large amount of energy consumption has become more and more serious. my country is a country where coal is the main energy source. The smoke, sulfur dioxide, nitrogen oxides and other harmful substances contained in coal-fired flue gas have caused serious air pollution. [0003] There are many types of flue gas desulfurization technologies for domestic coal-fired power plants, such as limestone-gypsum method, simple wet method, wet ammonia method, electron beam method, etc. The most widely used flue gas denitration technology is selective catalytic reduction technology (SCR) and selective non-catalytic reduction technology (SNCR). The denitration reaction...

AI Technical Summary

Problems solved by technology

There are many problems in the existing desulfurization and denitrification technologies, such as the large fixed investment and high cost of desulfurization of the limestone-gypsum method, and the large amount of gypsum produced is difficult to handle. Problems, SNCR technology has a series of problems such as high reaction temperature, poor mixing degree of reducing agent and flue gas, low denitrification efficiency, and large amount of ammonia gas escape.

Therefore, the current flue gas desulfurization and denitrification process has the following problems: low removal efficiency, short service life of the catalyst, generation of solid waste, ammonia escape, high investment cost, large installed capacity of the system, large floor area, high operating cost, and economical Low benefit
