Technical Field

[0001] The utility model relates to the technical field of chemical production collection devices, in particular to a gas collection device for chemical safety production. Background Technique

[0002] Chemical engineering is the abbreviation of chemical production technology. Any technology that uses chemical methods to change the composition, structure of substances or synthesize new substances belongs to chemical production technology. The products obtained are called chemical products or chemical industrial products. The harmful factors in chemical products will affect people's physical health. For the gases generated in the chemical production process, such as ethylene oxide, neopentyl glycol, etc., relevant collection devices need to be used for collection and treatment, so as to meet the rigid requirements of safety production.

[0003] An existing gas collection device for chemical safety production (Publication No.: CN220834855U) has at least the following drawbacks: The above device sprays water through the water spray holes to cover all the space inside the treatment tank, collects the gas inside the treatment tank, and the mixed solution enters the inner side of the middle part of the collection tank through the outlet end arranged at the bottom of the treatment tank for temporary storage. However, it is difficult to fully mix the gas and water only by the spraying method, which is easy to cause waste of water during the gas collection process, resulting in low gas collection efficiency and poor gas collection effect. Therefore, we propose the present utility model. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a gas collection device for chemical safety production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0022] As Figures 1 - 4 shown, a chemical safety production gas collection device includes a treatment tank 1. The top surface of the treatment tank 1 is fixedly connected and communicated with a water inlet pipe 2. The outer wall surface of the treatment tank 1 is fixedly connected and communicated with an air inlet pipe 3. A collection structure is arranged inside the treatment tank 1. The collection structure includes a partition board 201 fixed inside the treatment tank 1. A rotating rod 202 is rotatably arranged inside the treatment tank 1. A sprinkling plate 203 is fixed inside the treatment tank 1. The rotating rod 202 is rotatably arranged with the sprinkling plate 203. A water storage cavity 204 is opened inside the sprinkling plate 203. The bottom end of the water inlet pipe 2 is fixedly connected and communicated with the inside of the water storage cavity 204. A plurality of sprinkling holes 205 are opened on the bottom surface of the sprinkling plate 203. The sprinkling holes 205 are communicated with the water storage cavity 204. Fan blades 206 are fixed on the outer wall surface of the rotating rod 202.

[0023] In this embodiment, the fan blade 206 is located between the water sprinkling tray 203 and the partition plate 201. A driving motor is fixed on the top surface of the treatment tank 1. The output end of the driving motor penetrates through the top surface of the treatment tank 1 and is fixed to the top end of the rotating rod 202. A plurality of stirring plates 301 are fixed on the outer circumferential wall surface of the rotating rod 202. The stirring plates 301 are arranged obliquely, and the plurality of stirring plates 301 are evenly distributed along the circumference of the outer circumferential wall surface of the rotating rod 202. Through the setting of the collection structure, the staff injects the chemical gas between the water sprinkling tray 203 and the partition plate 201 in the treatment tank 1 through the air inlet pipe 3. Then, water is injected into the water storage cavity 204 in the water sprinkling tray 203 through the water inlet pipe 2. The water in the water storage cavity 204 is sprayed out through the water spraying holes 205 to spray the gas. During the spraying process, the staff starts the driving motor to drive the rotating rod 202 to rotate. The rotating rod 202 drives the fan blade 206 and the stirring plates 301 to rotate. The rotating fan blade 206 breaks up the sprayed water into small water droplets, making it better mix with the gas. When the fan blade 206 rotates, it blows the gas downward. At the same time, the stirring plates 301 stir the mixed solution generated by spraying on the top surface of the partition plate 201, keeping the mixed solution in a moving state. The gas moving downward contacts the moving mixed solution, so that the gas is further mixed and collected, thereby improving the gas collection efficiency and enhancing the gas collection effect.

[0024] In this embodiment, a plurality of flow disturbing plates 4 are fixed inside the treatment tank 1. The plurality of flow disturbing plates 4 are evenly distributed along the circumference of the inner circumferential wall surface of the treatment tank 1. The plurality of flow disturbing plates 4 are located between the fan blade 206 and the stirring plates 301, and there is a gap between the flow disturbing plates 4 and the stirring plates 301. When the stirring plates 301 stir the mixed solution, the flow disturbing plates 4 disturb the mixed solution, enhancing the movement intensity of the mixed solution and preventing the liquid level from rising due to vortex generated when the stirring plates 301 stir the mixed solution, which affects the spraying effect.

[0025] In this embodiment, a plurality of discharge holes 5 are opened on the top surface of the partition plate 201. A movable plate 501 is slidably arranged on the bottom surface of the partition plate 201. The movable plate 501 penetrates through the inner circumferential wall surface of the treatment tank 1 and extends to the outside of the treatment tank 1. When the water level of the mixed solution accumulated above the partition plate 201 reaches a certain level, the staff can pull out the movable plate 501 to cancel the blockage of the discharge holes 5 by the movable plate 501. The accumulated mixed solution is discharged through the discharge holes 5 to the lower part of the treatment tank 1, and the staff can collect it below the treatment tank.

[0026] In this embodiment, an observation hole 6 is opened on the outer circumferential wall surface of the treatment tank 1. A toughened glass 601 is fixed inside the observation hole 6. The observation hole 6 is a strip-shaped square hole. During the collection process, the staff can observe the water level of the mixed liquid in the treatment tank 1 through the observation hole 6, which is convenient for the staff to discharge it in time.

[0027] In this embodiment, a support ring 7 is fixed to the outer circumferential wall surface of the treatment tank 1, and a plurality of support rods are fixed to the bottom surface of the support ring 7. The movable plate 501 is slidably inserted into the outer circumferential wall surface of the support ring 7. Through the support ring 7 and the support rods, stable support can be provided for the treatment tank 1.

[0028] Working principle: During use, the staff injects chemical gas into the space between the water sprinkling tray 203 and the partition plate 201 in the treatment tank 1 through the air inlet pipe 3. Then, water is injected into the water storage cavity 204 in the water sprinkling tray 203 through the water inlet pipe 2. The water in the water storage cavity 204 is sprayed out through the water spraying holes 205 to spray the gas. During the spraying process, the staff starts the driving motor to drive the rotating rod 202 to rotate. The rotating rod 202 drives the fan blades 206 and the stirring plate 301 to rotate. The fan blades 206 rotate to break up the sprayed water into small water droplets, so that it can be better mixed with the gas. When the fan blades 206 rotate, they blow the gas downward. At the same time, the stirring plate 301 stirs the mixed solution generated by spraying on the top surface of the partition plate 201 to keep the mixed solution in a movable state. The gas moving downward contacts the movable mixed solution, so that the gas is further mixed and collected. When the stirring plate 301 stirs the mixed solution, the flow disturbing plate 4 disturbs the mixed solution to enhance the movement intensity of the mixed solution and prevent vortex from being generated when the stirring plate 301 stirs the mixed solution, resulting in the rise of the liquid level and affecting the spraying effect. When the water level of the mixed solution accumulated above the partition plate 201 reaches a certain level, the staff can pull out the movable plate 501 to cancel the blockage of the discharge hole 5 by the movable plate 501. The accumulated mixed solution is discharged through the discharge hole 5 to the lower part of the treatment tank 1, and the staff can collect it below the treatment tank. During the collection process, the staff can observe the water level of the mixed liquid in the treatment tank 1 through the observation hole 6, which is convenient for the staff to discharge it in time. Through the support ring 7 and the support rods, stable support can be provided for the treatment tank 1.
