Description

Technical Field

[0001] The utility model relates to the field of dehydrators, in particular to a cyclone dehydrator for a spray tower. Background Art

[0002] The spray tower is a common process facility for treating various acid-base waste gases, hydrophilic organic waste gases and other waste gases; during the operation of such waste gas treatment facilities, the washing liquid is extremely prone to generating droplets and being carried out of the exhaust pipe by the fan, and then falling to the surrounding ground and infiltrating into the soil after being discharged into the atmospheric environment, which not only causes secondary pollution to the external atmospheric environment and soil environment, but also some acid-base spray tower absorption liquids will cause damage to the surrounding facilities.

[0003] According to the disclosed patent 202220092766.7, a cyclone dehydrator for a spray tower, which includes a tank body, one side of the lower end of the tank body is fixedly connected with an air inlet pipe, the top of the tank body is fixedly connected with a water accumulation box, and the water accumulation box is circumferentially provided with water falling holes. It also includes: an outer ring cover fixedly connected to the water accumulation box, an inner ring cylinder fixedly connected inside the outer ring cover, and a sandwich is formed between the inner ring cylinder and the outer ring cover; in the utility model, by installing an outer ring cover and an inner ring cylinder at the top of the tank body, and installing a swirl vane in the inner ring cylinder, when the gas enters the tank body and rises, it drives the rotating shaft of the swirl vane to rotate at a high speed on the support frame, and collides with the water-containing waste gas during rotation and throws it onto the inner wall of the inner ring cylinder, thereby preventing water from being discharged out of the tank body through the exhaust pipe and avoiding environmental pollution. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. Although by installing the swirl vane in the inner ring cylinder, when the water-containing waste gas passes through the inner ring cylinder, it collides with the high-speed rotating swirl vane, throws the water droplets onto the inner wall of the inner ring cylinder, and enters the sandwich through the holes opened on the inner wall of the inner ring cylinder and then enters the water accumulation box for collection. This device can effectively separate water and gas, thereby preventing the washing liquid from being discharged out of the tank body and causing environmental pollution. However, during use, the surface area of the swirl vane of the traditional cyclone dehydrator for a spray tower is limited, resulting in a small contact area between the swirl vane and the water-containing waste gas, which easily causes a large amount of water-containing waste gas to pass through the swirl vane, affecting the cyclone dehydration effect. Moreover, after dehydrating and storing the water in the water-containing waste gas, the separated water is not fully utilized, resulting in waste of water resources. Therefore, new technical solutions need to be designed to solve this problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a cyclone dehydrator for a spray tower, so as to solve the technical problems of the cyclone dehydrator of the current traditional spray tower. The surface area of the cyclone vane is limited, resulting in a small contact area between the cyclone vane and the water-containing waste gas, which easily causes a large amount of water-containing waste gas to pass through the cyclone vane, affecting the cyclone dehydration effect. Moreover, after dehydrating and storing the water in the water-containing waste gas, the dehydrated water is not fully utilized, resulting in a waste of water resources.

[0005] In order to achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a cyclone dehydrator for a spray tower, including an outer cylinder, and further including:

[0006] An inner cylinder, which is arranged inside the outer cylinder, and a plurality of circular holes are opened on the inner wall of the inner cylinder;

[0007] A cyclone dehydration mechanism, which is arranged inside the inner cylinder. The cyclone dehydration mechanism includes two cyclone vanes, which are respectively arranged at the upper and lower ends inside the inner cylinder. One end of the cyclone vane is fixed with a bearing, and a connecting column is rotatably connected inside the bearing. The other end of the cyclone vane is fixed with a fixing ring;

[0008] A plurality of vertical blades are fixed between the upper and lower fixing rings.

[0009] Preferably, one end of a fixing rod is fixed on both sides of the connecting column, and the other end of the fixing rod is fixed with the inner cylinder.

[0010] Preferably, the surface of the vertical blade is integrally formed into a concave-convex surface.

[0011] Preferably, the bottom of the outer cylinder is communicated with an annular storage shell. Liquid pumps are installed on both sides of the bottom of the annular storage shell. The bottom of the liquid pump extends into the tank. One end of the liquid pump located inside the tank is communicated with a pipe body. A plurality of spray heads are communicated on one side of the pipe body. The bottom of the pipe body is of a sealed structure.

[0012] Preferably, the bottom of the inner cylinder passes through the outer cylinder and the annular storage shell and is communicated with a tank. The top of the inner cylinder is communicated with an exhaust pipe.

[0013] Preferably, an annular filter screen is fixed at the top end inside the annular storage shell. One end of a liquid outlet pipe is communicated with the bottom of the front end of the annular storage shell. The other end of the liquid outlet pipe is detachably connected with a pipe cap.

[0014] Preferably, a control host is installed at the top of the front end of the tank. An air inlet pipe is communicated with the bottom of the front end of the tank. A flange is installed at one end of the air inlet pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By combining the swirl vane, the fixing ring and the vertical blades, the utility model can utilize the gas to enter the inner cylinder, drive the swirl vane to rotate at high speed. The swirl vane after high-speed rotation will drive multiple vertical blades to rotate. Through the large-area contact and collision of the swirl vane and the vertical blades with the water-containing waste gas, the water droplets are thrown onto the inner wall of the inner ring cylinder, thereby dehydrating the water-containing waste gas over a large area, improving the dehydration effect of the water-containing waste gas. Moreover, the surface of the vertical blade is set as a concave-convex surface, which further increases the contact area with the water-containing waste gas by using the concave-convex surface, further improving the dehydration effect of the water-containing waste gas, and solving the technical problem that in the swirl dehydrator of the traditional spray tower, the surface area of the swirl vane is limited, resulting in less contact area between the swirl vane and the water-containing waste gas, and easily causing a large amount of water-containing waste gas to pass through the swirl vane, affecting the swirl dehydration effect.

[0017] 2. By combining the annular storage housing, the liquid pump and the pipe body, after the washing liquid in the waste gas enters the annular storage housing and is filtered by the filter screen to remove impurities, the liquid pump can pump out the washing liquid in the annular storage housing to spray the waste gas in the tank, thereby recycling the washing liquid to remove pollutants in the waste gas, and solving the technical problem that after the water in the water-containing waste gas is dehydrated and stored, the dehydrated water is not fully utilized, resulting in waste of water resources.

[0022] The present utility model will be further described below with reference to the drawings and embodiments:

[0023] Embodiment 1: A swirl dehydrator for a spray tower, see Figures 1 to 3, including an outer cylinder body 1, further comprising: an inner cylinder body 2 disposed inside the outer cylinder body 1, with a plurality of circular holes 206 formed on the inner wall of the inner cylinder body 2; a swirl dehydration mechanism disposed inside the inner cylinder body 2, the swirl dehydration mechanism including two swirl vanes 204, the two swirl vanes 204 being respectively disposed at the upper and lower ends inside the inner cylinder body 2, one end of each swirl vane 204 being fixed with a bearing 203, a connecting column 202 being rotatably connected inside the bearing 203, and the other end of each swirl vane 204 being fixed with a fixing ring 207; a plurality of vertical blades 205 being fixed between the upper and lower fixing rings 207. After the waste gas inside the tank body 105 enters the inner cylinder body 2, the waste gas will drive the swirl vanes 204 to rotate at a high speed. The swirl vanes 204 rotating at a high speed will drive the fixing rings 207 and the plurality of vertical blades 205 to rotate. By using the swirl vanes 204 and the plurality of vertical blades 205 to continuously and extensively contact the water-containing waste gas, after the swirl vanes 204 and the vertical blades 205 extensively contact and collide with the water-containing waste gas, the water foam is thrown onto the inner wall of the inner ring cylinder, and the water foam will pass through the circular holes 206 and enter the inside of the outer cylinder body 1. Since the bottom of the outer cylinder body 1 is communicated with the annular storage housing 102, the water foam will enter the annular storage housing 102, thereby dehydrating the water-containing waste gas extensively and improving the dehydration effect on the water-containing waste gas, solving the technical problem that in the swirl dehydrator of a traditional spray tower, the surface area of the swirl vane 204 is limited, resulting in less contact area between the swirl vane 204 and the water-containing waste gas, and easily causing a large amount of water-containing waste gas to pass through the swirl vane 204, affecting the swirl dehydration effect.

[0024] Specifically, refer to Figure 1 , one end of a fixing rod 201 is fixed to both sides of the connecting column 202, and the other end of the fixing rod 201 is fixed to the inner cylinder body 2.

[0025] Furthermore, refer to Figure 3 , the surface of the vertical blade 205 is integrally formed into a concave-convex surface 208. By setting the surface of the vertical blade 205 as the concave-convex surface 208, the contact area with the water-containing waste gas is further increased by using the concave-convex surface 208, and the dehydration effect on the water-containing waste gas is further improved.

[0026] It should be noted that, refer to Figure 2, a ring-shaped storage housing 102 is connected to the bottom of the outer cylinder 1. Liquid pumps 301 are installed on both sides of the bottom of the ring-shaped storage housing 102. The bottom of the liquid pump 301 extends into the tank 105. One end of the liquid pump 301 located inside the tank 105 is connected to a pipe body 302. A plurality of spray heads 303 are connected to one side of the pipe body 302. The bottom of the pipe body 302 is a sealed structure. After a large amount of water foam is stored inside the ring-shaped storage housing 102, the liquid pump 301 can be turned on. The washing liquid accumulated inside the ring-shaped storage housing 102 is pumped out through the liquid pump 301, input into the pipe body 302 and sprayed out through the plurality of spray heads 303, so as to spray the waste gas inside the tank 105, and the washing liquid is reused to remove pollutants in the waste gas, solving the technical problem that after the water in the water-containing waste gas is dehydrated and stored, the dehydrated water is not fully utilized, resulting in waste of water resources.

[0027] It should be noted that, refer to Figure 1 , the bottom of the inner cylinder 2 passes through the outer cylinder 1 and the ring-shaped storage housing 102 and is connected to the tank 105. The top of the inner cylinder 2 is connected to an exhaust pipe 101.

[0028] It is worth introducing that, refer to Figure 2 , a ring-shaped filter screen 3 is fixed to the top end inside the ring-shaped storage housing 102. One end of a liquid outlet pipe 103 is connected to the bottom of the front end of the ring-shaped storage housing 102. The other end of the liquid outlet pipe 103 is detachably connected to a pipe cap 104.

[0029] It should be emphasized that, refer to Figure 1 , a control host 106 is installed on the top of the front end of the tank 105. An intake pipe 107 is connected to the bottom of the front end of the tank 105. A flange is installed at one end of the intake pipe 107.

[0030] When using the cyclone dehydrator of a spray tower, after the waste gas in the tank body 105 enters the inner cylinder body 2, the waste gas will drive the swirl vanes 204 to rotate at a high speed. The swirl vanes 204 rotating at a high speed will drive the fixed ring 207 and multiple vertical blades 205 to rotate. By using the swirl vanes 204 and multiple vertical blades 205 to continuously and extensively contact the water-containing waste gas, after the swirl vanes 204 and vertical blades 205 extensively contact and collide with the water-containing waste gas, the water droplets are thrown onto the inner wall of the inner ring cylinder. The water droplets will pass through the round holes 206 and enter the outer cylinder body 1. Since the bottom of the outer cylinder body 1 is communicated with the annular storage shell 102, the water droplets will enter the annular storage shell 102, thereby dehydrating the water-containing waste gas extensively and improving the dehydration effect on the water-containing waste gas. The surface of the vertical blade 205 is set as the concave-convex surface 208, and the concave-convex surface 208 is used to further increase the contact area with the water-containing waste gas, further improving the dehydration effect on the water-containing waste gas. After more water droplets are stored in the annular storage shell 102, the liquid pump 301 can be opened. The washing liquid accumulated in the annular storage shell 102 is pumped out through the liquid pump 301 and sprayed into the pipe body 302 and multiple nozzles 303, thereby spraying the waste gas in the tank body 105 and recycling the washing liquid to remove pollutants in the waste gas.
