Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a spray-type waste gas treatment device for a granulation workshop. Background Technology

[0002] The treatment of exhaust gas from granulation workshops is an important environmental issue. These exhaust gases contain a variety of harmful substances, such as volatile organic compounds (VOCs), dust, and odorous substances. If they are not effectively treated, they will not only cause serious pollution to the environment, but also endanger human health.

[0003] Existing granulation workshops typically use spray devices for waste gas treatment. However, the spray liquid from these devices is unevenly distributed, making it difficult for the spray liquid to completely cover the waste gas. As a result, the waste gas is discharged without being purified, causing pollution. Therefore, a spray-type waste gas treatment device for granulation workshops that can uniformly mix waste gas and spray liquid is needed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a method in which the reaction force generated by the spray liquid ejected from a high-pressure nozzle drives the rotating drum to rotate, thereby driving the high-pressure nozzle to continuously rotate around the rotating drum, thus uniformly spraying the spray liquid. At the same time, the high-pressure spray liquid continuously stirs and mixes the waste gas, increasing the purification effect of the waste gas.

[0005] This utility model is achieved through the following technical solution: a spray-type waste gas treatment device for a granulation workshop is provided, including a box connected to a waste gas inlet and a waste gas outlet. A spray device is installed inside the box, located between the waste gas inlet and the waste gas outlet. The spray device includes a rotating drum rotatably mounted inside the box, with several high-pressure nozzles on the drum. The axes of the high-pressure nozzles are not parallel to the axis of the drum, and the high-pressure nozzles are arranged clockwise or counterclockwise around the drum. The high-pressure nozzles are connected to liquid delivery pipes. The reaction force generated by the spray liquid sprayed from the high-pressure nozzles drives the drum to rotate, thereby driving the high-pressure nozzles to continuously rotate around the drum, thus uniformly spraying the spray liquid. At the same time, the high-pressure spray liquid continuously stirs and mixes the waste gas, increasing the purification effect of the waste gas.

[0006] As an optimization, the rotating drum has inherent branch pipes, the axis of which intersects with or is not in the same plane as the axis of the rotating drum, and the high-pressure nozzles are arranged sequentially on the branch pipes; the coverage area of ​​the high-pressure nozzles is increased by the branch pipes.

[0007] As an optimization, the rotating drum has inherent stirring blades, the axis of which intersects with or is not parallel to the axis of the rotating drum; the stirring blades increase the mixing effect of the spray liquid and the exhaust gas, thereby increasing the purification effect of the exhaust gas.

[0008] As an optimization, the stirring blades are provided with several through holes, the axes of which are opposite to the axis of the rotating drum. The exhaust gas is dispersed through the through holes, increasing the contact area between the exhaust gas and the spray liquid, and at the same time increasing the mixing effect of the spray liquid and the exhaust gas, thereby increasing the purification effect of the exhaust gas.

[0009] The beneficial effects of this invention are as follows: the reaction force generated by the spray liquid ejected from the high-pressure nozzle drives the rotating drum to rotate, thereby driving the high-pressure nozzle to continuously rotate around the rotating drum, thus uniformly spraying the spray liquid. At the same time, the high-pressure spray liquid continuously stirs and mixes the waste gas, increasing the purification effect of the waste gas. The stirring blades increase the mixing effect of the spray liquid and waste gas, thereby increasing the purification effect of the waste gas. The through holes disperse the waste gas, increasing the contact area between the waste gas and the spray liquid, and at the same time increasing the mixing effect of the spray liquid and waste gas, thereby increasing the purification effect of the waste gas.

The rotating cylinder 201 is provided with a plurality of high-pressure nozzles 203. The axis of the high-pressure nozzles 203 is not parallel to the axis of the rotating cylinder 201, and the orientation of the high-pressure nozzles 203 is arranged clockwise or counterclockwise around the rotating cylinder 201. The high-pressure nozzles 203 are connected to a liquid delivery pipe 3. The rotating cylinder 201 extends along the exhaust gas transmission direction inside the box 1. The high-pressure nozzles 203 are arranged evenly around the rotating cylinder 201, and the axis of the high-pressure nozzles 203 is perpendicular to the axis of the rotating cylinder 201. The high-pressure nozzles 203 are connected to the liquid delivery pipe 3 through the rotating cylinder 201, and the liquid delivery pipe 3 is connected to a water pump.

[0016] Waste gas is introduced into the housing 1 through the waste gas inlet 101, and high-pressure spray liquid is introduced into the high-pressure nozzle 203 through the liquid delivery pipe 3. The high-pressure spray liquid is sprayed out from the high-pressure nozzle 203 and applies a reaction force to the high-pressure nozzle 203. Under the action of the reaction force, the high-pressure nozzle 203 drives the rotating drum 201 to rotate, and at the same time, the high-pressure nozzle 203 continuously rotates around the rotating drum 201. The spray liquid sprayed out by the high-pressure nozzle 203 is evenly sprayed inside the housing 1, and at the same time, the high-pressure spray liquid continuously stirs and mixes the waste gas.

[0017] like Figure 1 and Figure 2 The rotating drum 201 shown has a fixed branch pipe 202. The axis of the branch pipe 202 intersects with or is not in the same plane as the axis of the rotating drum 201. The high-pressure nozzles 203 are arranged sequentially on the branch pipe 202. The axis of the branch pipe 202 is perpendicular to the axis of the rotating drum 201. The branch pipes 202 are arranged sequentially and evenly around the rotating drum 201, and the branch pipes 202 are arranged sequentially and evenly along the axial direction of the rotating drum 201. The high-pressure nozzles 203 are connected to the rotating drum 201 through the branch pipe 202.

[0018] High-pressure spray liquid is introduced into the high-pressure nozzle 203 through the infusion tube 3; the high-pressure spray liquid is sprayed out from the high-pressure nozzle 203 and applies a reaction force to the high-pressure nozzle 203. Under the action of the reaction force, the high-pressure nozzle 203 drives the rotating drum 201 to rotate synchronously through the branch pipe 202.

[0020] The rotating drum 201 rotates and drives the stirring blades 4 to rotate synchronously, and the stirring blades 4 stir the spray liquid and the exhaust gas.

[0021] like Figure 1 and Figure 2 The stirring blade 4 shown has several through holes, the axis of which is not in the same plane as the axis of the rotating drum 201; the axis of the through holes is perpendicular to the axis of the rotating drum 201.

[0022] The stirring blade 4 rotates and agitates the spray liquid and exhaust gas, which then pass through the through hole and mix further.

[0023] In actual production, waste gas is input into the housing 1 through the waste gas inlet 101, and high-pressure spray liquid is input into the high-pressure nozzle 203 through the liquid delivery pipe 3. The high-pressure spray liquid is sprayed out from the high-pressure nozzle 203 and applies a reaction force to the high-pressure nozzle 203.
