Description

Technical Field

[0001] This utility model relates to the field of scrubbing tower technology, specifically to a tail gas scrubbing tower. Background Technology

[0002] The packing material in the washing tower is the core component of the washing tower. The packing material increases heat dissipation, extends the residence time of cooling water, and increases the heat exchange area, playing a significant role in the cooling effect of circulating water.

[0003] After long-term use, the packing needs to be cleaned or replaced. The traditional cleaning and replacement process first requires disassembling the old packing, cleaning up the garbage inside the tower and cleaning up the site. Then, the new packing is bonded, ensuring that the packing has sufficient space during the adhesive curing time, ensuring that the contact points of the packing are on the same horizontal plane and that the force is uniform and tight. The dust and garbage inside the cooling tower are cleaned, and the packing is stacked in the cooling tower in sequence, ensuring that each layer of packing blocks is neat and that the packing is tightly and seamlessly connected to the corners and around the columns, with a gap of no more than 2 mm.

[0004] The packing replacement process of the above-mentioned device involves many steps, resulting in low replacement efficiency and inconvenience. In addition, the replacement process is time-consuming, and the washing tower may be unable to function properly due to lack of packing material during the replacement process, which also causes inconvenience.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1

[0030] Reference Figure 1-4This is the first embodiment of the present invention, which discloses an exhaust gas scrubbing tower, including a base 1 and a water tank 2 installed on one side of the base 1 and communicating with the inner cavity of the base 1. A circulating water pump is installed in the water tank 2, and related equipment for treating waste liquid is also connected to the water tank 2. The waste liquid is purified into a clear liquid by neutralizing a precipitant using a chemical method. A tower body 3 is installed at the top of the base 1, and a spray head 22 connected to the output end of the circulating water pump is installed in the tower body 3. A scrubbing chamber 31 is opened in the tower body 3, and an air inlet 37 is opened through the scrubbing chamber 31 on the outer wall of the tower body 3. The air inlet 37 is located below the packing box 4 to ensure that the exhaust gas entering from the air inlet 37 will automatically pass through the packing box 4. The outer wall of the tower body 3 has a loading and unloading cavity 32 through the washing chamber 31. The bottom of the loading and unloading cavity 32 has a sliding groove 33 and an insertion hole 34 on one side of the sliding groove 33. The packing box 4 is detachably installed in the loading and unloading cavity 32. The packing box 4 has a packing cavity through the top and bottom. The bottom of the packing cavity is fixedly installed with a filter screen 41. The packing cavity is filled with packing. The filling height of the packing is not higher than the cavity height of the packing cavity, so as not to affect the loading and unloading of the packing box 4. The bottom of the packing box 4 is equipped with rollers 42 that are rolled in the corresponding sliding grooves 33. The bottom of the packing box 4 is also equipped with positioning plugs 49 that are inserted into the corresponding insertion holes 34 to improve the stability of the packing box 4 after it is installed in the tower body 3.

[0031] Example 2

[0032] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a spray pipe 21 connects the output end of the circulating water pump to the spray head 22; the input end of the circulating water pump connects to the inner cavity of the water tank 2; and a flow meter is installed at the connection point to facilitate adjustment of the spraying power of the circulating water pump. A top seat 35 is installed at the top of the tower body 3, and an exhaust pipe 36 connected to the washing chamber 31 is installed on the top of the top seat 35. A lifting handle 43 is provided on one side of the packing box 4. A spring 44 is installed between the lifting handle 43 and the packing box 4. One end of the spring 44 is fixed to the lifting handle 43, and the other end is fixed to the inner wall of the packing box 4. By pulling the lifting handle 43... The first rack 45 is moved, which in turn stretches the spring 44. The first rack 45 is vertically fixed on one side of the lifting handle 43 and is telescopically slidably installed inside the filling box 4. Two first gears 46 are meshed and installed below the first rack 45. A second gear 47 is fixedly installed on one side of each first gear 46. A second rack 48 is meshed and installed on one side of each second gear 47. The bottom end of the second rack 48 is fixedly connected to the corresponding positioning plug 49. Two fixed handles 410 are vertically fixed on the outer wall of the filling box 4, which are respectively set on the outside of the corresponding lifting handles 43, so as to make it easy to hold the fixed handles 410 and pull the two lifting handles 43 at the same time.

[0033] The remaining structure is the same as that in Example 1.

[0034] The workflow of this utility model is as follows:

[0035] First, the exhaust gas enters the washing chamber 31 through the air inlet 37. At the same time, the circulating water pump is started to draw water from the water tank 2 and supply water to the spray head 22 through the spray pipe 21. The water sprayed from the spray head 22 is sprayed onto the packing material and gradually sinks into the base 1 due to gravity, and finally flows back into the water tank 2. Because the molecular mass of the exhaust gas is smaller than that of air molecules and is continuously supplied, it will automatically rise and pass through the packing material. The packing material exchanges heat with the exhaust gas and filters large particulate impurities in the exhaust gas.

[0036] Secondly, the packing needs to be replaced after long-term use. The replacement method is to hold the two fixed handles 410 and pull the two lifting handles 43 at the same time, thereby pulling the first rack 45 towards the fixed handles 410. During this process, the two springs 44 are forced to compress to obtain elastic restoring force. The movement of the first rack 45 drives the two first gears 46 and the second gear 47 to rotate, thereby meshing and driving the second rack 48 to rise in height, so that the positioning plug 49 can be pulled out from the insertion hole 34 at the bottom of the loading and unloading cavity 32. At this time, the entire packing box 4 is no longer limited and fixed. Through the rollers 42 at the bottom of the packing box 4, it rolls in the corresponding sliding groove 33, reducing the wear between the bottom of the packing box 4 and the loading and unloading cavity 32, and also reducing the frictional resistance when replacing the packing.

[0037] Finally, the removed stuffing box 4 is flipped 180 degrees and the old stuffing is removed by heavy knocking and water flushing from top to bottom. New stuffing is then added. The disassembly steps are reversed until the stuffing box 4 is fully installed in the loading and unloading chamber 32, the stuffing inside the stuffing box 4 is in full contact with the washing chamber 31, and the positioning plugs 49 at the bottom of the stuffing box 4 are inserted into the insertion holes 34 on the loading and unloading chamber 32 to complete the positioning and fixing of the stuffing box 4.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
