Description

Technical Field

[0001] The utility model relates to the technical field of disperse dye production, in particular to an environmentally friendly waste gas treatment device for disperse dye production. Background Art

[0002] Disperse dyes are a type of non-ionic dye with smaller molecules and no water-soluble groups in their structure. They have low solubility in water and are highly dispersed in the dye solution through the action of dispersants. They are mainly suitable for dyeing synthetic fibers such as polyester and are characterized by bright colors and a complete color spectrum.

[0003] The waste gas generated during the disperse dye production process contains a variety of harmful substances, posing a potential threat to both the environment and human health. These waste gas components include volatile organic compounds (VOCs), including aromatic hydrocarbons, alcohols, and esters, which have a pungent odor and adversely affect air quality and human health. Acidic gases, such as H2S and SO2, are corrosive and can damage production equipment and potentially cause atmospheric pollution problems such as acid rain. Alkaline gases, such as ammonia, primarily originate from chemical reactions during the production process or from wastewater treatment. They are also irritating and corrosive, posing a threat to the environment and human health. Malodorous substances, such as sulfur-containing organic compounds like mercaptans and sulfides, and nitrogen-containing organic compounds like amines, have a strong pungent odor and can seriously impact the quality of life of surrounding residents and production personnel. Dust and smoke are generated during the disperse dye production process due to operations such as material crushing, grinding, and mixing. These particulates not only affect the air quality of the working environment but can also interfere with the normal operation of production equipment.

[0004] These waste gases need to be treated before being discharged to prevent them from polluting the environment. However, common environmentally friendly waste gas treatment devices for disperse dye production usually directly pass the waste gas into the bottom of the treatment liquid to treat harmful substances in the waste gas. The waste gas rises directly in the treatment liquid, which easily leads to insufficient contact between the harmful substances and the treatment liquid. In view of this, the present application proposes an environmentally friendly waste gas treatment device for disperse dye production. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an environmentally friendly waste gas treatment device for disperse dye production, which has the advantages of passing the waste gas through a rotatable hollow tube into a treatment tank to contact with the treatment liquid and stirring the treatment liquid. It solves the problem of directly passing the waste gas into the bottom of the treatment liquid to treat harmful substances in the waste gas, and the waste gas directly rises in the treatment liquid, which easily leads to insufficient contact between the harmful substances and the treatment liquid.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly waste gas treatment device for disperse dye production, comprising a mounting base, a treatment tank fixedly mounted on the top of the mounting base, a hollow tube rotatably mounted on the inner wall of the treatment tank, a branch pipe fixedly mounted on the surface of the hollow tube, an exhaust hole provided on the surface of the branch pipe, a mounting groove provided on the top of the mounting base, a driven gear fixedly mounted on the surface of the hollow tube located inside the mounting groove, and the bottom end of the hollow tube extends to the bottom of the mounting base.

[0007] Furthermore, a driving gear meshing with the driven gear is rotatably mounted inside the mounting groove, and a rotating motor having an output shaft fixedly connected to the bottom of the driving gear is fixedly mounted at the bottom of the mounting base.

[0008] Furthermore, a bracket is placed below the mounting base, an adsorption filter assembly is fixedly mounted on the top of the bracket, and one end of the adsorption filter assembly is rotatably connected to the bottom end of the hollow tube.

[0009] Furthermore, the adsorption filter assembly includes a filter tank, a filter element is fixedly installed inside the filter tank, an input end flange of the filter tank is connected to an air inlet pipe, and an output end flange of the filter tank is connected to a connecting pipe.

[0010] Furthermore, an air intake connector is fixedly installed at one end of the air intake pipe, a connecting head is fixedly installed at one end of the connecting pipe, an air outlet pipe is fixedly installed at the top of the processing tank, and a supporting leg is fixedly installed at the bottom of the processing tank.

[0011] Furthermore, a liquid inlet pipe is fixedly installed on one side of the processing tank near the top, and a liquid inlet valve is fixedly installed on one end of the liquid inlet pipe. A liquid discharge pipe is fixedly installed on one side of the processing tank near the bottom, and a liquid discharge valve is fixedly installed on one end of the liquid discharge pipe.

[0012] Furthermore, connecting studs are fixedly installed at both ends of the filter tank, connecting flanges are fixedly installed at one end of the air intake pipe and the connecting pipe, and connecting nuts are threadedly installed on the surfaces of the connecting studs.

[0013] Compared with the prior art, the present invention provides an environmentally friendly waste gas treatment device for disperse dye production, which has the following beneficial effects:

[0014] The environmentally friendly waste gas treatment device for disperse dye production is provided with a rotatable hollow tube in a treatment tank, a branch tube is provided on the surface of the hollow tube, and an exhaust hole is opened on the surface of the branch tube. The waste gas is passed into the hollow tube, and then passed into the treatment liquid in the treatment tank through the exhaust hole on the surface of the branch tube.
