Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a purification tower. Background Art

[0002] The purification tower introduces the exhaust gas into the purification tower through the air duct. After the exhaust gas rises and passes through the packing layer, it is fully in contact with the liquid to absorb and neutralize the gas. In order to improve the treatment effect of the exhaust gas, the current purification tower generally has two or more layers of packing areas. After the purification tower has been used for a period of time, the packing balls in the packing area need to be replaced. The existing replacement method is to open a window on the wall of the purification tower corresponding to the packing area. When the packing balls need to be replaced, the window is opened, the packing balls are manually pulled out of the window, and then the new packing balls are re-spread on the packing rack to achieve the replacement of the packing balls.

[0003] The above replacement method has the following problems: the filler area is partially located below the window, so it is very difficult to pull or spread the filler balls outward, and the labor intensity of the workers is high; and the filler in only one filler area can be replaced at a time, and the replacement efficiency is low. Utility Model Content

[0004] The utility model aims to provide a purification tower, wherein multiple packing layers are interconnected up and down, and when it is necessary to discharge packing balls, the packing outlet is opened, and the packing balls are discharged in sequence from the bottom outlet, thereby discharging the packing balls of all packing layers at one time; when it is necessary to fill packing balls, the window of the packing inlet is opened, and the packing balls fall in sequence under the action of gravity, thereby filling all packing layers, thereby achieving one-time filling of all packing layers, greatly improving replacement efficiency and reducing the labor intensity of workers.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a purification tower including a tower body, wherein an air inlet is arranged at the bottom of the tower body and an air outlet is arranged at the top surface of the tower body; a liquid storage area, at least two packing layers and a demisting layer are arranged in sequence between the air inlet and the air outlet in the tower body; the packing layer is filled with packing balls, and the upper and lower adjacent packing layers are connected to each other; a spray layer is arranged correspondingly above each packing layer, and the spray layer is connected to the liquid storage area through a water pump; a packing inlet is arranged above the uppermost packing layer on the tower body, and a packing outlet is arranged below the lowermost packing layer on the tower body, and windows are respectively arranged on the packing inlet and the packing outlet; the packing inlet is connected to the uppermost packing layer through a pipeline, and the packing outlet is connected to the lowermost packing layer through a pipeline.

[0006] After adopting the above structure, the packing inlet is higher than the top packing layer and is connected to the top packing layer, the upper and lower adjacent packing layers are connected to each other, and the packing outlet is lower than the bottom packing layer and is connected to the bottom packing layer; when packing balls need to be filled, the packing balls are injected from the packing inlet, and under the action of gravity, the packing balls fill the packing layers of each layer in turn, realizing one-time filling of the packing balls; when the packing balls need to be replaced, the packing outlet is opened, and the packing balls are discharged from the packing layers in turn, realizing one-time replacement of the packing balls; the replacement efficiency is improved and the labor intensity of workers is reduced.

[0007] In order to guide the packing balls and facilitate the replacement and discharge of the packing balls, a packing rack is fixedly installed on the inner wall of the tower body in the packing layer area, and a packing cavity is arranged in the packing rack. The bottom and top of the packing cavity are provided with conical surfaces, and hollow structures are evenly distributed on the conical surfaces; a feed port is arranged at the minimum diameter of the upper conical surface, and a discharge port is arranged at the minimum diameter of the lower conical surface; the feed port is connected to the discharge port or the packing inlet of the adjacent packing cavity above, and the discharge port is connected to the feed port or the packing outlet of the adjacent packing cavity below.

[0008] In order to reduce the speed of the packing balls and avoid the packing balls from piling up in the middle of the packing cavity, which would cause the packing cavity to be unable to be filled, a baffle plate is hung on the feed port to form a feed channel between the baffle plate and the side wall of the packing cavity, through which the packing balls can enter.

[0009] In order to prevent the baffle plate from blocking the spraying liquid and gas, the baffle plate is a hollow plate.

[0010] In order to improve the strength of the baffle plate, the baffle plate is an upwardly convex arc plate.

[0011] In order to ensure the connection strength of the baffle plate, the baffle plate is fixed to the upper conical surface through a plurality of connection plates.

[0012] In order to prevent the packing balls in the pipeline from failing to play a purifying role and causing waste when replacing the packing balls, the packing inlet and the feed port, as well as the packing outlet and the discharge port are connected through inclined hollow pipes.

[0013] In order to facilitate the knocking of the packing rack, cause the packing rack to vibrate, and assist the smooth discharge of the packing balls, a knocking hole is provided on the side wall of the tower body corresponding to the side wall of the packing layer. A sealing cover is provided on the knocking hole. After opening the sealing cover, the outer side wall of the packing rack can be knocked.

[0014] In order to make the best use of the space at the bottom of the filling rack and ensure the coverage area of ​​the spray layer, the spray pipe includes a first annular tube and a second annular tube with a diameter smaller than that of the first annular tube. The first annular tube and the second annular tube are coaxially arranged and have a certain height difference. The first annular tube and the second annular tube are connected by a connecting pipe, and the first annular tube and the second annular tube are connected to a water pump through a four-way pipeline.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] The positions mentioned in this specification are based on the positions of a purification tower of the utility model during normal operation, and do not limit the positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0023] like Figure 1As shown, a purification tower includes a tower body 1, an air inlet 11 is arranged at the bottom of the tower body 1, and an air outlet 12 is arranged on the top surface of the tower body 1; a liquid storage area 2, at least two packing layers 3 and a demisting layer 4 are arranged in sequence between the air inlet 11 and the air outlet 12 in the tower body 1; in this embodiment, the packing layer 3 is arranged with two layers above and below, and in actual application, three layers or other number of layers can be arranged according to the treatment effect and site restrictions, which is not limited in this embodiment. The packing layer 3 is filled with packing balls; a spray layer 5 is arranged above each packing layer 3, and the spray layer 5 is connected to the liquid storage area 2 through a water pump. The waste gas is introduced into the tower body 1 from the air inlet 11, and after the waste gas rises and passes through the packing layer 3, it is fully contacted with the liquid sprayed by the spray layer 5, so as to absorb and neutralize the gas, thereby achieving waste gas purification, and the purified gas passes through the demisting layer 4 and is discharged from the air outlet 12.

[0024] The upper and lower adjacent packing layers 3 are interconnected; a packing inlet 13 is provided above the uppermost packing layer 3 on the tower body 1, and a packing outlet 14 is provided below the lowermost packing layer 3 on the tower body 1, and windows are provided on the packing inlet 13 and the packing outlet 14 respectively; the packing inlet 13 is connected to the uppermost packing layer 3 through a pipeline, and the packing outlet 14 is connected to the lowermost packing layer 3 through a pipeline. The packing inlet 13 is higher than the uppermost packing layer 3, and the packing outlet 14 is lower than the lowermost packing layer 3, and the upper and lower adjacent packing layers 3 are interconnected, and the packing balls are injected from the packing inlet 13, and then under the action of gravity, the packing balls fill the packing layers 3 of each layer in turn, thereby realizing the filling of the packing balls; when it is necessary to replace the packing balls, the packing outlet 14 is opened, and the packing balls are discharged from the packing layer 3 in turn, thereby realizing the replacement of the packing balls. When the packing balls are discharged, you can choose to discharge all or partially discharge them for replacement. This is because after the exhaust gas enters, the packing balls at the bottom are in contact with the exhaust gas first, so they fail faster, while the packing balls at the top fail slower. If they are replaced together, the utilization rate of the packing balls at the top is not fully utilized. Therefore, you can choose to release the packing balls at the bottom, and let the packing balls at the top fall to the bottom, and then re-install new packing balls on the top to better play the role of the packing balls and reduce costs.

[0025] like Figure 2 As shown, a packing frame 31 is fixedly installed on the inner wall of the tower body 1 in the packing layer 3 area, and a packing cavity is arranged in the packing frame 31. The bottom and top of the packing cavity are both provided with conical surfaces, and hollow structures are evenly distributed on the conical surfaces; a feed port 311 is provided at the minimum diameter of the upper conical surface, and a discharge port 312 is provided at the minimum diameter of the lower conical surface; the feed port 311 is connected to the discharge port 312 or the packing inlet 13 of the adjacent packing cavity above, and the discharge port 312 is connected to the feed port 311 or the packing outlet 14 of the adjacent packing cavity below. By setting the feed port 311 and the discharge port 312 at the minimum diameter of the conical surface, the conical surface guides the packing balls to ensure the smooth falling of the packing balls.

[0026] When the packing balls fall, in order to reduce the speed of the packing balls and prevent the packing balls from accumulating in the center of the packing cavity, which causes the packing cavity to be unable to be filled, a baffle plate 32 is suspended on the feed port 311, and the baffle plate 32 is fixed to the upper conical surface through multiple connecting plates. A feed channel is formed between the baffle plate 32 and the side wall of the packing cavity, and the packing balls can enter from the feed channel. In order to avoid the baffle plate 32 blocking the spray liquid, the baffle plate 32 is a hollow plate; in order to enhance the impact resistance of the baffle plate 32, the baffle plate 32 is an upwardly convex arc plate.

[0027] In order to prevent the packing balls from falling too fast, the packing inlet 13 and the feed port 311, and the packing outlet 14 and the discharge port 312 are connected through inclined hollow pipes. The hollow pipes ensure that the packing balls in the pipes also play a purification role, and prevent the pipe wall from blocking the entry of gas and spray liquid.

[0028] In order to prevent the packing balls from getting stuck when falling, a knocking hole 15 is provided on the side wall of the tower body 1 corresponding to the side wall of the packing layer 3. A sealing cover is provided on the knocking hole 15. After opening the sealing cover, the outer side wall of the packing frame 31 can be knocked to cause vibration, thereby ensuring the smooth falling of the packing balls.

[0029] like Figure 1 and Figure 3 As shown together, in order to make full use of the bottom space of the packing frame 31 and increase the coverage area of ​​the spray layer 5 as much as possible, the spray layer 5 includes a spray pipe 51 and a nozzle 511 evenly distributed on the spray pipe 51 and spraying the packing layer 3 at the bottom thereof; the spray pipe 51 includes a first annular tube and a second annular tube with a diameter smaller than the first annular tube, the first annular tube and the second annular tube are coaxially arranged and have a certain height difference; the first annular tube and the second annular tube are connected through a connecting tube 52, and the first annular tube and the second annular tube are connected to a water pump through a four-way pipe 53. The spray pipe 51 is fixed at the bottom of the packing frame 31. Because the packing frame 31 has a conical bottom, by making a certain height difference between the fixed heights of the first annular tube and the second annular tube, the bottom space of the packing frame 31 is fully utilized, the height difference between the spray liquid and the packing layer is increased, the coverage of the spray liquid is ensured, and the spraying effect is improved.

[0030] The utility model discloses a purification tower which solves the technical problems of low efficiency and high labor intensity in replacing packing balls in the purification tower in the prior art. The utility model connects multiple packing layers up and down with each other. When it is necessary to discharge the packing balls, the window of the packing outlet is opened, and the packing balls are discharged in sequence from the bottom outlet, thereby discharging the packing balls of all packing layers at one time; when it is necessary to add packing balls, the window of the packing inlet is opened, and the packing balls fall in sequence under the action of gravity, thereby filling all packing layers, thereby realizing that all packing layers can be filled with one-time addition, thereby greatly improving the replacement efficiency and reducing the labor intensity of workers.
