Problems solved by technology

[0003] In the conventional process, desulfurization and dust removal are completed as independent unit operations in their respective devices. This independent exhaust gas treatment process is costly, wastes space, and has a complicated process. Therefore, it is necessary to develop an integrated desulfurization, denitrification and dust removal process. equipment, so as to achieve the two purposes of desulfurization and dust removal

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The embodiment of the present invention provides an integrated equipment for desulfurization, denitrification and dust removal, such as figure 1 As shown, it includes the first desulfurizer 1, the first dust remover 2, the second dust remover 3 and the second desulfurizer 4, the first desulfurizer 1, the first dust remover 2, the second dust remover 3 and the second desulfurizer The desulfurizers 4 are connected in sequence.

[0031] Further, the second desulfurizer can also communicate with a preset SCR denitrification device, so as to denitrify the flue gas. The SCR denitrification device includes a catalyst injector for injecting powder catalyst into the flue flow passage. The powder catalyst may be a catalyst that catalyzes the selective catalytic red...

Abstract

The invention provides a desulfurization, denitration and dedusting integrated system. The integrated system comprises a first desulfurizer, a first deduster, a second deduster and a second desulfurizer which are communicated in order, the second desulfurizer can also be connected to a preset SCR denitration device to facilitate denitration of the flue gas, the first deduster and the second deduster are connected by a fence baffle plate, and the first deduster and the second deduster are both funnel-shaped dedusters. The integrated system can better achieve the purpose of desulfurization, denitration and dedusting based on the multi-pass continuous process. A plurality of desulfurizing agents and various dedusting agents are used in the whole process, and the automatic preparation of a dedusting agent as well as the automation of desulfurization and dedusting are realized, the efficiency of desulfurization and dedusting is improved, and the desulfurization and dedusting effect is alsobetter.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an integrated equipment for desulfurization, denitrification and dust removal. Background technique [0002] As my country's main primary energy source, coal occupies a large proportion of energy consumption in power plants, boilers and coking industries. Especially this year, with the development of my country's economy, the increase in energy demand has greatly increased the consumption of coal. consume. When coal is burned, sulfur dioxide will be produced. For the coking industry, the carbonization chamber of the coke oven is heated by the gas heating vertical fire channel to provide the heat source. The waste gas generated after the gas heating contains more sulfur dioxide, nitrogen oxides and particulate matter. emissions, which are extremely serious for air pollution. [0003] In the conventional process, desulfurization and dust removal are completed as independent...
