Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment devices, and particularly to an easily cleanable and non-clogging cooling tower. Background Art

[0002] At present, during the wastewater treatment process, cooling towers are often used to reduce the water temperature of wastewater to meet the needs of biological wastewater treatment. Most of the fillers in existing cooling towers are honeycomb fillers, which can play a role in reducing the water temperature of wastewater. However, since the honeycomb fillers have fixed pore diameters, the garbage components contained in the wastewater are easily accumulated on the filler walls, clogging the filler holes. Moreover, the honeycomb fillers are usually fixedly placed in the cooling tower. After being clogged, people need to enter the cooling tower for cleaning or remove the honeycomb fillers for cleaning, which is not only very troublesome but also requires production suspension for cleaning. These defects of conventional cooling towers directly affect their stable operation and the normal use of the sewage treatment system. Summary of the Invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an easily cleanable and non-clogging cooling tower that is basically not clogged during continuous use, does not require production suspension for cleaning the cooling filler layer, improves the operation stability, has a simple structure, and is easy to clean.

[0004] The present invention is achieved through the following technical solutions: An easily cleanable and non-clogging cooling tower includes a tower body, a suction fan, a wastewater distributor, a rotatable cooling filler layer, and a slag removal and water collector. The suction fan is arranged at the top of the tower body, the wastewater distributor and the rotatable cooling filler layer are respectively arranged inside the tower body, and the wastewater distributor is located above the rotatable cooling filler layer. The rotatable cooling filler layer is detachably connected to the tower body. The slag removal and water collector is arranged at the bottom of the tower body. The tower body is provided with a wastewater inlet and an air inlet. The wastewater inlet is communicated with the wastewater distributor, and the air inlet is located between the rotatable cooling filler layer and the slag removal and water collector.

[0005] Furthermore: The wastewater distributor includes a water inlet pipe, a main water distribution trough, and branch water distribution troughs. The water inlet pipe is respectively communicated with the main water distribution trough and the wastewater inlet. Both sides of the main water distribution trough are respectively communicated with a plurality of parallel and spaced branch water distribution troughs.

[0006] Furthermore: The main water distribution trough and the branch water distribution troughs are respectively cuboid structures with open tops. The top side walls of the branch water distribution troughs are provided with triangular weirs, and the bottom angles of the triangular weirs are 90°.

[0007] Furthermore, the rotatable cooling packing layer is composed of multiple packing structures. There is a gap between every two adjacent packing structures. Each packing structure is composed of multiple round tubes arranged in parallel at intervals. Both ends of each round tube are rotatably inserted into the mounting holes on both side walls of the tower body, and the ends of the round tubes extend out of the tower body from the mounting holes.

[0008] Furthermore, the round tubes of every two adjacent packing structures are staggeredly distributed.

[0009] Furthermore, both ends of each round tube are limited in the mounting holes by a limiting component.

[0010] Furthermore, the limiting component includes a limiting ring and a limiting cylinder. The limiting ring is fixedly sleeved on one end of the round tube, and the limiting cylinder is detachably sleeved on the other end of the round tube. The diameters of both the limiting ring and the limiting cylinder are larger than the diameter of the mounting hole.

[0011] Furthermore, the slag removal and water collector includes a water collecting tray, a slag separator, and a connecting pipe. The water collecting tray is in a shape with a high middle and low corners. The slag separators are respectively arranged at the four corners of the water collecting tray. The connecting pipe is arranged below the water collecting tray and is communicated with the slag separator. A waste water outlet is arranged on the connecting pipe.

[0012] Furthermore, the slag separator includes a slag separating plate and a water tank. A plurality of water permeable holes are arranged on the slag separating plate. The slag separating plate is arranged on the top of the water tank, and the water tank is communicated with the connecting pipe.

[0013] Furthermore, a slag cleaning door is arranged on the side wall of the tower body, and the slag cleaning door is located beside the slag separating plate.

[0014] Advantages of the present invention:

[0015] Compared with the prior art, by detachably arranging the rotatable cooling packing layer inside the tower body, the rotatable cooling packing layer is composed of multiple layers of packing structures, and each layer of packing structure is composed of multiple round tubes arranged in parallel at intervals. Both ends of each round tube are rotatably inserted into the mounting holes on both side walls of the tower body, and the end portions of the round tubes extend out of the tower body from the mounting holes. When the wastewater flows towards the round tubes, the round tubes rotate freely under the hydraulic action of the wastewater. When the round tubes rotate, the garbage carried on the round tubes slides freely to the slag removal and water collector at the bottom of the tower body, so as to achieve the effect of unloading the garbage on the round tubes. In addition to the rotation of the round tubes under the hydraulic action of the wastewater, the round tubes can also be rotated by an external force. If it is difficult to unload the garbage on the round tubes by rotating the round tubes, the round tubes are drawn out of the tower body through the mounting holes. During the process of drawing out the round tubes, the garbage carried on the round tubes is resisted by the hole wall of the mounting holes, so that the garbage is scraped off at the bottom of the tower body. While achieving the cooling effect, the sewage cooling tower can avoid the accumulation of garbage in the wastewater on the round tubes, resulting in the blockage of the cooling packing layer, so as to realize that the sewage cooling tower is basically not blocked during continuous use. Even if the cooling tower is blocked, it is not necessary to take out the entire cooling packing layer of the cooling tower, without the need for production suspension cleaning, without the need to replace the entire cooling packing layer, and even less need to enter the cooling tower for cleaning, improving the stability of the operation of the cooling tower, with a simple structure and facilitating the cleaning of the cooling packing layer. By arranging a slag removal and water collector at the bottom of the tower body, the garbage in the wastewater is collected and separated through the slag removal and water collector, which can eliminate the influence on the subsequent process.

[0028] The waste water distributor 3 includes a water inlet pipe 31, a main water distribution trough 32, and branch water distribution troughs 33. The water inlet pipe 31 is respectively communicated with the main water distribution trough 32 and the waste water inlet 11. Both sides of the main water distribution trough 32 are respectively communicated with a plurality of branch water distribution troughs 33 that are arranged in parallel at intervals.

[0029] The main water distribution trough 32 and the branch water distribution troughs 33 are respectively cuboid structures with open tops. The top of the side wall of the branch water distribution trough 33 is provided with a triangular weir 34, and the bottom angle of the triangular weir 34 is 90°.

[0030] The rotatable cooling packing layer 4 is composed of multiple layers of packing structures 41. There is a gap between every two adjacent layers of packing structures 41. Each layer of packing structure 41 is composed of a plurality of round pipes 42 that are arranged in parallel at intervals. Both ends of each round pipe 42 are rotatably inserted into the mounting holes on both side walls of the tower body 1 respectively, and the ends of the round pipes 42 extend out of the tower body 1 from the mounting holes.

[0031] The round pipes 42 of every two adjacent layers of packing structures 41 are arranged in a staggered manner.

[0032] Both ends of each round pipe 42 are limited in the mounting holes by a limiting component.

[0033] The limiting component includes a limiting ring 61 and a limiting cylinder 62. The limiting ring 61 is fixedly sleeved on one end of the circular tube 42, and the limiting cylinder 62 is detachably sleeved on the other end of the circular tube 42.

[0034] The slag removal and water collector 5 includes a water collecting tray 51, a slag separator 52, and a connecting pipe 53. The water collecting tray 51 has a shape with a higher middle part and lower four corners. The four corners of the water collecting tray 51 are respectively provided with slag separators 52.

When the waste water flows onto the circular tube 42 of the rotatable cooling filler layer 4, the circular tube 42 rotates freely under the hydraulic action of the waste water. When the circular tube 42 rotates, the garbage carried on the circular tube 42 slides freely to the slag removal and water collector 5 at the bottom of the tower body 1, thus achieving the effect of unloading the garbage on the circular tube 42. In addition to the circular tube 42 rotating under the hydraulic action of the waste water, the circular tube 42 can also be rotated by an external force. If it is difficult to unload the garbage on the circular tube 42 by rotating the circular tube 42, the limiting cylinder 62 is pulled out from the end of the circular tube 42, and then the circular tube 42 is drawn out of the tower body 1 through the mounting hole. During the process of drawing out the circular tube 42, the garbage carried on the circular tube 42 is resisted by the hole wall of the mounting hole, so that the garbage is scraped off at the bottom of the tower body 1.
