[0025] like Figure 1 and Figure 2 As shown, this embodiment provides a spray tower water tank purification device, which is suitable for wastewater purification, especially for wastewater purification of dust and other particulate matter in the spray tower circulating water tank. The spray tower water tank purification device of this embodiment mainly includes a purified water tank 3, a water inlet 1, a water outlet 2 and a sewage outlet 5, wherein the water inlet 1 of the spray tower water tank purification device is connected to the water pump of the spray tower water tank 41 and the waterway extension pipeline between the spray tower 4, so that the circulating water in the spray tower 4 enters the purified water tank 3 through the water inlet 1.

[0026] The water outlet 2 of the spray tower water tank purification device is connected to the spray tower water tank 41. When the circulating water of the spray tower 4 enters the purified water tank 3 to complete purification, the purified water in the purified water tank 3 enters the spray tower water tank 41 through the water outlet 2, that is, the direction of the water from the water inlet 1 to the purified water tank 3 and then to the water outlet 2 is the direction of water purification flow. The purified water tank 3 has at least two sewage outlets 5, which are used for the purified water tank 3 to directly discharge the residual sewage after purification to the outside world, thereby improving purification efficiency and quality.

[0027] When the spray tower water tank purification device is connected to the spray tower 4 for operation, when the waste water of the spray tower flows back into the spray tower water tank 41, part of the waste water continues to flow into the spray tower 4 under the water pump pressure in the spray tower water tank 41 to continue the spraying work, and another part of the waste water flows through the water channel extension pipe between the water pump and the spray tower 4 to the water inlet 1 of the spray tower water tank purification device and enters the purification water tank 3 for wastewater purification. After the purification is completed, the purified water enters the spray tower water tank 41 from the water outlet 2, thereby realizing circulating water purification.

[0028] like Figures 3 to 5As shown, the purified water tank 3 includes a box body 31, a cover plate 32, a lock 33, a first filter area 34, and a second filter area 35, wherein the box body 31 and the cover plate 32 can be made of flame-retardant materials such as flame-retardant polypropylene, and a sealing strip is arranged between the box body 31 and the cover plate 32, wherein the sealing strip can be an O-type sealing strip. The sealing strip makes the box body 31 and the cover plate 32 form a watertight space at the top to prevent the purified water in the box body 31 from overflowing from the top outside the box. The cover plate 32 includes at least two perspective windows 321, and the perspective windows 321 correspond to the first filter area 34 and the second filter area 35 respectively, and are used to observe the purification conditions of the first filter area 34 and the second filter area 35. A lock 33 is also arranged between the box body 31 and the cover plate 32, and the lock 33 is used to quickly clamp the box body 31 and the cover plate 32.

[0029] like Figure 6 to Figure 7 As shown, the first filter area 34 includes a filter screen 341 and a filter plate 342. The filter screen 341, the filter plate 342, the box body 31 and the cover plate 32 form an independent space that can accommodate liquid, namely the first filter area 34. The top contact area between the cover plate 32 and the first filter area 34 is provided with a sealing strip, wherein the sealing strip can be an O-type sealing strip. The sealing strip enables the cover plate 32 and the first filter area 34 to form a watertight space at the top, preventing the purified water in the first filter area 34 from overflowing from the top outside the box. The first filter area 34 can filter and remove substances with larger particles, and the larger particles between the filter plates can be removed by slag removal. The second filter area 35 includes a filter bag pressing plate 351 and a water filter bag 352. The pressing plate 351 can be made of flame-retardant materials such as flame-retardant polypropylene. The pressing plate 351 is provided with at least two holes corresponding to the openings of the water filter bag 352. The water filter bag 352 is placed downward through the holes corresponding to the openings of the water filter bag 352 on the pressing plate 351. The opening of the water filter bag 352 is in the holes of the pressing plate 351 and faces the cover plate 32, so that the water after filtration in the first filter area 34 flows downward into the water filter bag 352 to continue secondary purification and filtration of finer particulate matter. The pressing plate 351 and the water filter bag 352 are fixed by a detachable nut. The pressing plate 351 is provided with a handle for easy disassembly and separation of the pressing plate 351 and the water filter bag 352.

[0030] In some embodiments, a three-way pipe fitting and an overflow valve may be provided in the waterway extension pipeline between the water pump of the spray tower water tank 41 and the spray tower 4, for constant pressure overflow of the water pressure of the waterway pipeline, to ensure that the water pressure of the spray system and the purification device is balanced and stable, and they operate at the same time. A ball valve may be provided in the waterway extension pipeline between the water pump of the spray tower water tank 41 and the spray tower 4, and the ball valve is used to control the wastewater entering the purification water tank 3 by rotating the ball. The three-way pipe fitting, the overflow valve, and the ball valve may be provided and used at the same time.

[0031] In some embodiments, the water outlet 2 is connected to the upper side wall of the spray tower water tank 41 to prevent wastewater from flowing back. A ball valve can be provided in the pipe connecting the water outlet 2 of the spray tower water tank purification device and the spray tower water tank 41 to control the wastewater from entering the spray tower water tank 41 to prevent wastewater from flowing back.

[0032] In some embodiments, the water inlet 1 is arranged on the box 31 in the first filter area 34, and the water outlet 2 is arranged on the water filter bag 352, so that the direction of the water path from the water inlet 1 to the first filter area 34, then to the second filter area 35 and then to the water outlet 2 is the water path purification flow direction.

[0033] In some embodiments, the sewage outlet 5 includes a first sewage outlet 51 and a second sewage outlet 52. The first sewage outlet 51 and the second sewage outlet 52 are respectively arranged in the first filter area 34 and the second filter area 35, so as to discharge sewage separately according to the sewage conditions of different purification areas and improve the purification quality and efficiency.

[0034] In some embodiments, the filter screen 341 and the filter plate 342 in the first filter area 34 are placed in parallel in the slot to form a group of filter elements. The two groups of filter elements are arranged opposite to each other, and no filler is arranged between the filter elements to facilitate the filtering of water. The two groups of filter elements are arranged in a direction parallel to the water flow of the water inlet 1. The two groups of filter elements and the two side boxes 31 have gaps that can accommodate the passage of water. When the water flows in from the water inlet 1, after passing through the two groups of filter elements on both sides to filter larger particulate matter, it flows into the second filter area 35 from the gaps on both sides.

[0035] In some embodiments, the filter bag pressing plate 351 and the water filter bag 352 in the second filter area 35 are set at a lower height than the first filter area 34, and a space for water flow is left between the filter bag pressing plate 351 and the water filter bag 352 and the cover plate 32, so that the water flow can flow downward into the water filter bag 352 for a second purification after the water flow is purified in the first filter area 34. Finally, it returns to the water tank of the spray tower to realize the circulation purification of wastewater during the working process. The spray tower can purify the water tank while working, which greatly improves the dust removal effect and spraying effect of the spray tower, ensures the normal and efficient operation of the spray tower, and reduces the operation and maintenance cost of the spray tower.

[0036] Finally, it should be emphasized that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
