[0028] For example, Figure 1 and Figure 2As shown, the application provides a gas negative pressure extraction device, which comprises a water tank 1, the top of the water tank 1 is provided with an exhaust pipe 2, one side wall of the water tank 1 is provided with an air inlet pipe 3, one end of the air inlet pipe 3 located in the water tank 1 is provided with a gas dispersion assembly 4, the gas dispersion assembly 4 is arranged in the water of the water tank 1, and a water absorption assembly 5 is arranged in the water tank 1 in a plug-in manner above the air inlet pipe 3; the water absorption assembly 5 comprises a water absorption groove 51, water absorption cotton 52 and a fixed plate 53, the water absorption groove 51 is arranged in the water tank 1 in a plug-in manner, the fixed plate 53 is used for fixing the water absorption cotton 52 in the water absorption groove 51, and a plurality of air holes 6 are uniformly arranged on the bottom of the water absorption groove 51 and the fixed plate 53; in use, the extracted gas enters the water tank 1 through the air inlet pipe 3, the gas dispersion assembly 4 at one end of the air inlet pipe 3 is located in the water of the water tank 1, the gas dispersion assembly 4 disperses the gas into small bubbles, so that the gas is fully contacted with water, and the water preliminarily adsorbs the dust in the gas; in the rising process of the gas containing water vapor and dust, the water absorption assembly 5 arranged in the water tank 1 in a plug-in manner is passed, the water absorption cotton 52 in the water absorption assembly 5 is fixed by the fixed plate 53 and the water absorption groove 51, contacts with the gas through the air holes 6, and the water absorption cotton 52 adsorbs the water vapor in the gas; the gas treated by the water vapor and part of the dust is discharged through the exhaust pipe 2 at the top of the water tank 1, wherein the water absorption assembly 5 is arranged in the water tank 1 in a plug-in manner, compared with the edge of the water absorption cotton 52 being bonded to the inner wall of the water tank 1 in the prior art, the water absorption assembly 5 is greatly facilitated to be taken out and replaced, when the water absorption cotton 52 in the water absorption assembly 5 needs to be replaced due to saturation, the water absorption groove 51 can be directly taken out for treatment without the aid of tools for cutting or dissolving adhesive, so that the maintenance time is greatly reduced, and damage to the structure of the water tank 1 is avoided.

[0029] As shown in the drawings, Figure 2 The inner wall of the water tank 1 is provided with a limiting groove 11 matched with the water absorption groove 51, and the circumferential side of the water absorption groove 51 is provided with a sealing strip 511 used for sealing the gap between the water absorption groove 51 and the limiting groove 11; when the water absorption groove 51 is inserted into the limiting groove 11, the two are tightly matched, the limiting groove 11 provides a stable and accurate installation position for the water absorption groove 51, and the sealing strip 511 on the circumferential side of the water absorption groove 51 is extruded and tightly attached to the wall of the limiting groove 11 in the insertion process, effectively filling the gap between the two, so that the gas containing water vapor can only contact with the water absorption cotton 52 through the air holes 6 at the bottom of the water absorption groove 51 according to the designed path, improving the purification degree of the gas, avoiding the gas from leaking to other areas of the water tank 1 through the gap, eliminating the safety hazard caused by gas leakage, and ensuring the safety of the working environment.

[0030] As shown in the drawings, Figure 2As shown, the top of the water absorption groove 51 is provided with a support groove 512 matched with the fixed plate 53, the bottom of the fixed plate 53 is embedded with a magnet 531, and the fixed plate 53 is adsorbed in the support groove 512 by the magnet 531. The water absorption cotton 52 is placed in the water absorption groove 51 and below the fixed plate 53. The fixed plate 53 can press and fix the water absorption cotton 52. During the operation of the device, the gas flows through the air hole 6 at the bottom of the water absorption groove 51. Due to the fixing effect of the fixed plate 53, the water absorption cotton 52 will not be displaced due to the flow of gas, ensuring that the water absorption cotton 52 is always in full contact with the gas, and the adsorption of water vapor function is stable. Among them, the fixed plate 53 is fixed by the adsorption of the magnet 531. Workers do not need to use additional tools. They only need to place the fixed plate 53 with the magnet 531 close to the support groove 512 at the top of the water absorption groove 51 to easily complete the installation of the fixed plate 53, greatly shortening the installation time and improving the work efficiency. When the water absorption cotton 52 needs to be replaced, the worker only needs to overcome the adsorption force of the magnet 531 to easily take out the fixed plate 53, and then conveniently replace the water absorption cotton 52, effectively reducing the labor and time cost required for maintenance.

[0031] As shown in Figure 1 and Figure 2 , the outer side of the water absorption groove 51 is fixedly provided with a pull handle 513, and the top of the fixed plate 53 is fixedly provided with a lifting handle 532. The height of the lifting handle 532 is less than the distance between the top of the fixed plate 53 and the top of the water absorption groove 51. The pull handle 513 effectively improves the convenience of installation and disassembly of the water absorption groove 51. The position of the water absorption groove 51 in the water tank 1 can be easily controlled through the pull handle 513, improving the operation efficiency. The lifting handle 532 provides convenience for the maintenance work of the fixed plate 53. The maintenance personnel can quickly take down the fixed plate 53 through the lifting handle 532, and then quickly replace the water absorption cotton 52, reducing the difficulty and complexity of the maintenance work.

The top of the air dispersing groove 41 is connected with the air inlet pipe 3. The air dispersing plate 42 is uniformly provided with a plurality of air dispersing holes 421. The gas enters the air dispersing groove 41 through the air inlet pipe 3, and then is discharged downward through the air dispersing holes 421 on the air dispersing plate 42. In the process of discharging, the originally concentrated gas flow is divided by the uniformly distributed air dispersing holes 421 to form a plurality of small gas flows, so that the gas is dispersed into a large number of tiny bubbles in the water of the water tank 1, realizing the uniform dispersion of the gas in the water, greatly increasing the contact area between the gas and the water, and enabling the dust in the gas to be more fully contacted with the water, thereby improving the adsorption efficiency of the water on the dust.

[0033] As shown in Figure 1 and Figure 2As shown, the water tank 1 is provided with a water inlet pipe 7 and a drain pipe 8, the water inlet pipe 7 is below the water suction assembly 5, the drain pipe 8 is below the water inlet pipe 7, the water inlet pipe 7 is provided with a water inlet valve 71, and the drain pipe 8 is provided with a drain valve 81. When it is necessary to supplement water into the water tank 1, the water inlet valve 71 is opened, and the external water source flows into the water tank 1 through the water inlet pipe 7, when the water in the water tank 1 needs to be replaced, the drain valve 81 is opened, and the water in the water tank 1 flows out through the drain pipe 8 under the action of gravity.

[0034] As shown in Figure 1 and Figure 2 As shown, the exhaust pipe 2 is provided with an exhaust valve 21, and the air inlet pipe 3 is provided with an air inlet valve 31. During the gas extraction process, the opening degree of the air inlet valve 31 can be adjusted to control the flow and speed of the gas entering the water tank 1 to adapt to different gas extraction requirements, and the opening degree of the exhaust valve 21 can be adjusted to adjust the exhaust flow to ensure the stability of the internal pressure of the water tank 1.
