[0002] The vacuum pump in the desulfurization system usually adopts a water-ring vacuum pump. Its working principle is that the impeller in the pump cavity is eccentrically installed in the pump body. When starting, a certain amount of water is filled in the pump body as the working fluid to seal the vacuum, and suction, compression, and exhaust are realized through the change of volume during operation.

There are defects in the drainage treatment of the traditional exhaust device, resulting in the gas outlet being easily blocked by condensed water, affecting the smoothness of exhaust.

[0021] The outer wall of the diversion square pipe 47 is fixedly connected to the inner wall of the frame 1, the outer wall of the frame 1 is fixedly connected to the outer wall of the heat dissipation plate 45, the outer wall of the guide air pipe 41 is fixedly connected to the inner wall of the frame 1, the bottom of the fixed cylinder 42 is fixedly connected to the top of the base 4, the drainage mechanism 2 includes a drainage shell 24, a diversion cover 22 is fixedly connected to the top of the drainage shell 24 through a support column 23, gas can move from the diversion cover 22 to the outside, and the bottom of the support column 23 is fixedly connected to the top of the drainage shell 24. The outer wall of the top of the drainage shell 24 is fixedly connected to a top cover 21.

[0022] The bottom of the drainage housing 24 is fixedly connected to an intake circular pipe 25. The outer wall of the bottom of the drainage housing 24 is fixedly connected to an exhaust pipe 26. A drainage groove 27 is formed in the wall of the drainage housing 24.

The outer wall of the top cover 21 is fixedly connected to the outer wall of the frame 1. The outer wall of the exhaust pipe 26 is fixedly connected to the inner wall of the frame 1. The inner wall of the frame 1 is fixedly connected to the outer wall of the drainage housing 24. The bottom of the intake circular pipe 25 is fixedly connected to the top of the fixed cylinder 42.

[0023] Working principle:

[0024] During use, first, the exhaust pipe on the desulfurization vacuum pump needs to be connected to the intake pipe 5 on the frame 1, so that the high-temperature gas in the desulfurization vacuum pump can enter the exhaust mechanism 3 through the intake pipe 5. After the high-temperature gas is processed by the exhaust mechanism 3, the gas is discharged outside the device. The drainage mechanism 2 in the frame 1 is used to converge the moisture in the gas in the drainage mechanism 2, and then use the drainage mechanism 2 to discharge the water out of the frame 1. Similarly, the drainage mechanism 2 can be used to prevent external water from entering the frame 1, thus affecting the normal operation of the device.

[0025] After the exhaust pipe on the desulfurization vacuum pump is connected to the intake pipe 5, the high-temperature gas in the exhaust pipe will enter the guide pipe 41 along the intake pipe 5 and be blown onto the cooling column 46 through the guide pipe 41. The cooling column 46 is connected to the heat dissipation plate 45 through the heat conduction plate 44, and the temperature of the cooling column 46 is reduced through the heat dissipation plate 45. Therefore, when the high-temperature gas contacts the cooling column 46, the water vapor in the high-temperature gas is condensed by using the temperature difference, and the temperature of the high-temperature gas is reduced. The condensed water droplets slide down along the cooling column 46 to the bottom of the fixed cylinder 42 on the base 4, and are discharged from the diversion square pipe 47 out of the frame 1 under the push of the gas, and at the same time, the water droplets at the bottom of the fixed cylinder 42 are driven to be discharged out of the frame 1. The gas that is not discharged from the diversion square pipe 47 will pass through the filter plate 43 and be discharged upward from the fixed cylinder 42 and transported to the drainage mechanism 2.

[0026] The high-temperature gas discharged from the fixed cylinder 42 enters the drainage housing 24 through the intake circular pipe 25 and blows onto the flow guide cover 22. As the subsequent high-temperature gas contacts the flow guide cover 22 on the support column 23, due to the temperature difference between the flow guide cover 22 and the high-temperature gas, the water vapor in the high-temperature gas will converge on the flow guide cover 22 and slide along the inner wall of the flow guide cover 22 into the drainage groove 27 in the drainage housing 24. The water that enters the drainage groove 27 will be discharged from the frame 1 along the air outlet pipe 26, and the water discharged from the air outlet pipe 26 will drip downward onto the heat dissipation plate 45, thereby assisting the heat dissipation plate 45 in cooling. When the external water enters the frame 1 along the holes in the top cover 21, it will first drip onto the flow guide cover 22 and also drip onto the drainage groove 27 along the outer wall of the flow guide cover 22, and then drip from the air outlet pipe 26 onto the heat dissipation plate 45.
