[0043] In the industrial waste gas treatment process, the waste gas is preliminarily removed of large-particle dust in the spray tower. However, the gas after spraying carries a large amount of water vapor, and if it directly enters the subsequent filtering and adsorbing equipment, the water is adsorbed on the filtering material in large quantities, causing blockage.

[0044] Based on this, the utility model embodiment provides a water vapor separation device for waste gas treatment process, which is connected to the gas outlet end of the spray tower. The water vapor separation device comprises a three-way pipe, a water storage assembly and a cyclone assembly.

[0046] The technical solutions of the utility model are further illustrated below in combination with the drawings and through specific embodiments.

[0047] As Figure 2 , Figure 3 , Figure 4 The utility model discloses a water vapor separation device for waste gas treatment process is provided, and is connected to the gas outlet end of spray tower 1, and the water vapor separation device includes tee pipe 4, water storage assembly 6 and cyclone assembly 5. The first port 41 of tee pipe 4 is connected to spray tower 1, and the second port 42 is connected to dry filter box 2. The water storage assembly 6 is arranged on the third port 43 of the tee pipe 4, and the third port 43 is located below the first port 41 and the second port 42. The cyclone assembly 5 is arranged on the tee pipe 4 at a position close to the first port 41, and the cyclone assembly 5 at least includes the cyclone vane 52 of the cooler 51. The cooler 51 is arranged on the outside of the tee pipe 4, and the cyclone vane 52 is arranged in the tee pipe 4.

[0048] Specifically, the water vapor separation device can be installed in the waste gas treatment process between the spray tower 1 and the dry filter box 2 to separate the water vapor in the waste gas after spraying. The tee pipe 4 has a first port 41, a second port 42 and a third port 43, the first port 41 and the third port 43 are on the same vertical line, and the third port 43 is below the first port 41 and the second port 42. The first port 41 of the tee pipe 4 is connected to the gas outlet end of the spray tower 1, and the second port 42 is connected to the gas inlet end of the dry filter box 2. The cyclone assembly 5 is arranged on the tee pipe 4 and located on the side close to the first port 41, for separating the water vapor in the waste water. Among them, the cooler 51 can be a circulating water cooling cooler 51, a air-cooled cooler 51 and the like, for continuously providing cold to the inside of the tee pipe 4 at the location; the cyclone vane 52 is a spiral vane structure similar to a screw.

[0049] The waste gas is sprayed by the spray tower 1, enters the tee pipe 4 from the third port 43 and flows downward, when the waste gas flows through the cyclone assembly 5, the cyclone vane 52 increases the flow path of the waste gas, the time of the waste gas flow through the cyclone vane 52 part is increased, the cooler 51 arranged outside the tee pipe 4 can continuously cool the waste gas flowing through the cyclone vane 52 part, the water vapor in the waste gas can be condensed into liquid water, and the liquid water can directly drip or flow along the wall of the tee pipe 4 to the third port 43 and enter the water storage assembly 6, and the separated waste gas can enter the dry filter box 2 from the second port 42. Thus, the water vapor in the waste gas can be separated, the waste gas carrying a large amount of water vapor can be effectively avoided to enter the dry filter box 2 and the activated carbon adsorption box 3 at the rear end, and then the dry filter box 2 and the activated carbon adsorption box 3 can be avoided to be blocked due to the adsorption of a large amount of water by the filter material and the adsorption material, and the absorption effect and the service life of the dry filter box 2 and the activated carbon adsorption box 3 can be improved.

[0050] For example, the wall of the tee pipe 4 can be a metal pipe or a glass pipe with high thermal conductivity at the position where the cooler 51 is arranged, so as to improve the heat exchange efficiency between the cooler 51 and the tee pipe 4.

[0051] As shown in Figure 3 , Figure 4 and Figure 5 , in the embodiment of the utility model, the cyclone assembly 5 further includes a gas collecting pipe 53 and an air inlet funnel 54. The cyclone vane 52 is sleeved on the outer wall of the gas collecting pipe 53, and a plurality of air outlet holes 531 are spirally and spaced apart on the wall of the gas collecting pipe 53 close to the upper end. The air inlet funnel 54 is connected to the top end of the gas collecting pipe 53.

[0052] Specifically, the air inlet funnel 54 is connected to the top end of the gas collecting pipe 53, the waste gas enters the gas collecting pipe 53 from the air inlet funnel 54, and then flows in the gas collecting pipe 53 and enters the lumen where the cyclone vane 52 is located from the air outlet hole 531. The speed of the waste gas flow through the cyclone assembly 5 can be further slowed down, and the separation effect of the water vapor in the waste gas can be improved.

[0053] Further, the cyclone assembly 5 further includes a leakage member 55. The leakage member 55 is movably arranged at the lower end of the gas collecting pipe 53. The leakage member 55 can prevent the waste gas from flowing out from the bottom end of the gas collecting pipe 53, and the liquid water condensed in the gas collecting pipe 53 can be collected at the bottom of the gas collecting pipe 53 and then seep out and drip to the water storage assembly 6 through the leakage member 55. At the same time, the dust and other small particulate matters mixed in the waste gas can also be collected at the bottom of the gas collecting pipe 53 and filtered by the leakage member 55. The leakage member 55 is movably installed at the bottom of the gas collecting pipe 53, and can be replaced or maintained regularly to avoid blockage of the leakage member 55.

[0054] As shown in Figure 4 , Figure 5As shown, in an embodiment of the utility model, cyclone assembly 5 further includes baffle 56. Baffle 56 is fixedly connected to cyclone vane 52, and multiple baffles 56 are arranged at intervals.

[0055] Specifically, baffle 56 is a vertical plate fixed to cyclone vane 52, multiple baffles 56 are arranged at intervals in a spiral manner along cyclone vane 52, and the adjacent two baffles 56 are arranged in an up-down staggered manner, that is, one of the two adjacent baffles 56 is fixedly connected to cyclone vane 52 at the lower end, and the other is fixedly connected to cyclone vane 52 at the upper end. When the exhaust gas flows through cyclone vane 52, the water vapor in the exhaust gas will adhere to the inner wall of three-way pipe 4 and cyclone vane 52, and baffle 56 can increase the adhesion area of water vapor and improve the water vapor separation efficiency. At the same time, the adjacent two baffles 56 are arranged in an up-down staggered manner, so that the exhaust gas can flow in an S-shaped flow direction when flowing through cyclone vane 52, which can further slow down the flow speed of the exhaust gas and improve the water vapor separation efficiency.

[0056] Further, a guide groove 57 is formed on cyclone vane 52, and the guide groove 57 is spiral downward. After the water vapor adhering to the wall of three-way pipe 4, cyclone vane 52 and baffle 56 is condensed into liquid water, it can flow down along the guide groove 57.

[0057] Still further, cyclone assembly 5 can further include a fan, which is arranged inside the gas collecting pipe 53 and located at the upper end of the gas collecting pipe 53. The fan is arranged towards the inside of the gas collecting pipe 53, and the fan can accelerate the rate of exhaust gas entering the gas collecting pipe 53. The fan blows air into the gas collecting pipe 53, which can accelerate the circulation of exhaust gas in the gas collecting pipe 53 and discharge it from the air outlet 531, avoiding the accumulation of exhaust gas in the gas collecting pipe 53.

[0058] Still further, the inner wall of three-way pipe 4 has a hydrophobic coating, and the outer surface of cyclone vane 52 and the outer surface of baffle 56 can also be coated with a hydrophobic coating. This can reduce water droplet adhesion and promote the rapid flow of condensed water to the third port 43.

After flowing through the cyclone assembly 5, the exhaust gas enters the air outlet pipe 7 from the second port 42 and enters the dry filter box 2 from the air outlet pipe 7. The exhaust gas after passing through the cyclone assembly 5 can still carry water vapor, so that the water vapor can be attached to the wall of the air outlet pipe 7, and the water droplets after condensation can flow in the air outlet pipe 7, and the water droplets on the wall of the tee pipe 4 close to the first port 41 side can also flow into the air outlet pipe 7. Therefore, the air outlet pipe 7 is inclined to be arranged, so that the water droplets in the air outlet pipe 7 can be prevented from flowing into the dry filter box 2, and the water vapor separation effect is further improved.

[0060] As shown in Figure 3 , Figure 4 In the utility model embodiment, the water storage assembly 6 comprises a sealing cover 61, a water leakage bucket 62 and a water collecting bottle 63. The sealing cover 61 is movably connected to the third port 43 of the tee pipe 4; the water leakage bucket 62 is arranged in the sealing cover 61; and the water collecting bottle 63 is screwed to the bottom of the sealing cover 61 and communicates with the water leakage bucket 62.

The water droplets flowing down along the wall of the tee pipe 4 can permeate through the water permeable plate 64 and then fall on the water leakage bucket 62, and meanwhile, the water permeable plate 64 can block the exhaust gas from entering the cavity of the tee pipe 4 below to prevent the exhaust gas from gathering in the lower section of the tee pipe 4.

[0063] For example, the water storage assembly 6 comprises the sealing cover 61, an electromagnetic valve and a liquid level sensor, and the electromagnetic valve is installed on the sealing cover 61, and when the accumulated water level reaches a set value, the electromagnetic valve is opened to automatically drain water.
