High-temperature-resistant compressible smoke gas desulfurization and denitrification device for coal electricity plant

Abstract

The invention relates to a high-temperature-resistant compressible smoke gas desulfurization and denitrification device for a coal electricity plant. The desulfurization and denitrification device comprises a first main body and a filtering disc, wherein a condensing pipe is arranged at the inner side of the first main body; the right side of the condensing pipe is connected with a backflow pipe through screw threads; the left side of the top of the first main body is provided with a connecting pipe in a penetrating way; the bottom end of the connecting pipe is connected with a spraying head.The desulfurization and denitrification device has the beneficial effects that through the arrangement of a first movable bag, a second movable bag, a tube body and a movable cover, the cross sectionradian of the first movable bag is identical to that of the second movable bag; when the device is used for performing pre-compression treatment on smoke gas, a first hydraulic rod is started; the second movable bag is subjected to pushing operation; the region space at the right side inside the first main body is reduced; the pre-compression treatment on the smoke gas is convenient, so that the smoke gas fast enters a second main body; under the combined action of the first movable bag and a second hydraulic rod, compression operation is performed; the desulfurization and denitrification workefficiency of the device on the smoke gas is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization and denitrification in coal power plants, in particular to a high temperature resistant and compressible flue gas desulfurization and denitrification device for coal power plants. Background technique [0002] In recent years, the problem of air pollution has become more and more serious. As a large developing country, my country will still face the severe situation of increasing air pollution for a long time to come. The issue of atmospheric pollution control has been attracting great attention all over the world, and it is necessary to desulfurize and denitrify the flue gas through a high-temperature-resistant and compressible flue gas desulfurization and denitrification device. [0003] The existing desulfurization and denitrification devices do not have the function of compressing the flue gas during use, which reduces the working efficiency of the device, and when the device i...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a desulfurization and denitrification device for high temperature resistant and compressible flue gas used in coal power plants, so as to solve the problem that the existing desulfurization and denitrification devices proposed in the background technology do not have the ability to compress the flue gas during use. function, which reduces the working efficiency of the device, and when the device is performing desulfurization and denitrification work on the flue gas, the inner side of the device is prone to deposits, and it is difficult to perform the discharge operation, which makes the desulfurization and denitrification effect of the device on the flue gas not good.
