A flue gas dedusting device for zinc-containing dust sludge treatment and its application method

Abstract

The invention discloses a flue gas dedusting device for zinc-containing dust sludge treatment, comprising a dedusting device, a connecting pipe assembly and a plasma purifier; the dedusting device is installed on a bracket, and the dedusting device is connected with the plasma purifier through the connecting pipe assembly ; The air inlet end of the main dust removal tank is connected with the air intake pipe, the air outlet end of the main dust removal tank is connected with the exhaust pipe, the side of the main dust removal tank close to the air inlet end is connected with the air inlet of the auxiliary dust removal tank through the first communication pipe, and the auxiliary dust removal tank is connected with the air inlet of the auxiliary dust removal tank. The air outlet of the dust removal tank is connected with the exhaust pipe through the second communication pipe; the internal structure of the main dust removal tank is the same as that of the auxiliary dust removal tank, both are equipped with dust removal components, and the filter cotton is arranged on the inner wall of the main dust removal tank close to the intake pipe , the other end of the main dust removal tank is connected with the first installation plate through the flange, the filter element assembly is installed on the side of the first installation plate, and the inner wall of the main dust removal tank is provided with a positioning ring for installing the filter element assembly; the present invention has a purification effect Well, the advantage of ease of use.

Description

technical field [0001] The invention belongs to the technical field of zinc-containing dust and sludge treatment, and relates to a flue gas dust removal device and a use method thereof, in particular to a flue gas dust removal device for zinc-containing dust mud treatment and a use method thereof. Background technique [0002] Iron and steel / non-ferrous metallurgical enterprises will produce dust, mud, slag and other solid wastes with different zinc content in each process in actual production. [0003] In the prior art, a group of dust removal tanks is usually set up for dust removal work, and a group of dust removal tanks can only process a certain amount of flue gas per unit time. When the flow rate of flue gas is too large, it will exceed the load of the dust removal tank , so that the problem that the flue gas cannot be effectively treated; when the dust removal tank needs to be replaced according to the production process, since the length of the connecting pipe is fix...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, a group of dust removal tanks is usually set up for dust removal work, and a group of dust removal tanks can only process a certain amount of flue gas per unit time. When it is too large, it will exceed the load of the dust removal tank, so that the smoke cannot be effectively treated; when the dust removal tank needs to be replaced according to the production process, since the length of the connecting pipe is fixed, usually the welding extension connecting pipe or the cutting connecting pipe are used Shorten the length of the connecting pipe, and this method makes the use of the connecting pipe extremely inconvenient, and proposes a flue gas dedusting equipment for zinc-containing dust and sludge treatment and its use method
