Industrial dry flue gas desulfurization, denitrification and dust removal integrated purification equipment

Abstract

The invention discloses industrial dry flue gas desulfurization, denitrification and dust removal integrated purification equipment which comprises an outer shell, wherein the outer shell is installed in a flue gas treatment workshop; a cooling water tank, wherein the interior of the cooling water tank is filled with cooling water; a dust shaking-off device which is rotationally mounted in a dust filtering cylinder; a sealing cover plate which is connected to the interior of a communicating channel in a clamping manner; and a desulfurizer which is mounted and connected to the upper end of the interior of the outer shell. According to the industrial dry type flue gas desulfurization, denitrification and dust removal integrated purification equipment, flue dust carried in flue gas is conveniently and fully collected and treated before flue gas treatment, the later desulfurization and denitrification work progress is prevented from being influenced, heat carried in the flue gas is conveniently and fully absorbed and collected during flue gas treatment, meanwhile, when the flue gas is subjected to desulfurization and denitrification, the flue gas can be in full contact with the purification device conveniently, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the related technical field of industrial dry flue gas purification, in particular to an integrated purification equipment for industrial dry flue gas desulfurization, denitrification and dust removal. Background technique [0002] Industrial flue gas is a mixture of gas and smoke, which is one of the main causes of air pollution. At present, the control of coal-burning pollutants by enterprises mainly focuses on dust removal, desulfurization and denitrification. Flue gas desulfurization refers to the pollution from flue gas or other industrial Sulfur oxides are removed from exhaust gas, and denitrification refers to the process of removing nitrogen oxides from combustion flue gas. Flue gas desulfurization and denitrification technologies can be divided into two categories: wet method and dry method. The following mainly focuses on dry method flue gas treatment instructions . [0003] Refer to the authorized announcement numbe...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an industrial dry flue gas desulfurization, denitrification and dust removal integrated purification equipment to solve the problem that the existing flue gas purification device proposed in the above background technology is inconvenient to clean the flue gas before the flue gas is processed. The smoke and dust carried in the air will be fully collected and processed, which will affect the desulfurization and denitrification work in the later stage. The dust in the flue gas will be directly discharged into the air, which will easily cause dust pollution and affect the air quality. The heat carried in the air is fully absorbed and utilized, which is easy to cause heat waste and is not convenient to protect the environment. At the same time, when the flue gas is desulfurized and denitrified, it is inconvenient for the flue gas to fully contact with the purification device, which affects the work efficiency. The desulfurization and denitrification device in the authorized patent has complicated installation and disassembly methods, and it is not convenient to disassemble the desulfurization and denitrification device, and it is inconvenient to repair and deal with the problem later
