Desulfurization, denitration and dust removal equipment for flue gas of chemical plant

Abstract

The invention discloses desulfurization, denitrification and dust removal equipment for flue gas of a chemical plant, and belongs to the technical field of chemical production, wherein the equipment comprises a shell, two partition plates and a rotary dust removal mechanism; the two partition plates are mounted in the shell up and down and divide the shell into three cavities from bottom to top, and the three cavities are respectively a first-stage dust removal cavity, a second-stage dust removal cavity and a drying cavity from bottom to top; and the rotary dust removal mechanism is arranged in the first-stage dust removal cavity and used for conducting first-stage dust removal treatment on the flue gas, and an operation door is hinged to the left side face of the shell. The two partition plates are arranged to divide the shell into the first-stage dust removal cavity, the second-stage dust removal cavity and the drying cavity, first-stage dust removal treatment is conducted through a coarse filter screen in the first-stage dust removal cavity, and second-stage dust removal treatment is conducted through water in the second-stage dust removal cavity in cooperation with flue gas sprayed out of a spray head and a fine filter screen; and a heating plate is matched with two flow guide seats to dry the gas, so that the flue gas can be effectively dedusted, the structure is simple, the use is convenient, and the dedusting precision is high.

Problems solved by technology

[0004] The purpose of the present invention is to provide a flue gas desulfurization and denitration and dust removal equipment in chemical plants to solve the problem that the existing flue gas desulfurization and denitrification equipment in chemical plants is still doped with dust after desulfurization and denitrification, and the gas is directly discharged. Sometimes it will affect the environment, the environmental performance is poor, and the function is not perfect.
