[0002] A recirculating cooling tower is a device used in industrial and commercial refrigeration systems. Its core function is to reduce process heat loads by circulating water or other cooling media. These cooling systems fall into two main categories: open circuit cooling towers and closed circuit cooling towers, each with its own specific design and operating principles.

The utility model installs a filter bucket built into the top end of the return pipe so that the filter bucket performs preliminary filtration on the recovered water flow, thereby reducing the probability of condensed solid matter entering the water collection tank. At the same time, the filter plate design built into the water collection tank can perform secondary filtration on some fine solid matter, further reducing the impurity content in the water flow, and avoiding the condensed particles in the water collection tank from flowing through the water distribution pipe after the water flow circulates and accumulating continuously, resulting in clogging of the spray nozzle.

[0004] When the above-mentioned closed cooling tower with high efficiency cooling is in operation, when furfural is circulated and cooled in the cooling tower for a long time, the furfural residue will form scaling on the surface of the heat exchanger, resulting in a decrease in the cooling effect of the heat exchanger. Utility Model Content

[0005] The utility model proposes a circulating cooling type furfural cooling tower, which solves the problem that when the closed cooling tower with high efficiency cooling in the related art is working, when the furfural is circulated and cooled in the cooling tower for a long time, the furfural residue will form scaling on the surface of the heat exchanger, resulting in a decrease in the cooling effect of the heat exchanger.

[0007] The descaling assembly includes a cleaning liquid tank, a connecting pipe is sealedly connected to the side of the cleaning liquid tank, the other end of the connecting pipe is sealedly connected to the regulating valve box, a rotating column is rotatably connected in the regulating valve box, a blocking valve is fixed on the rotating column, a rotating handle is fixed on the top of the rotating column, a delivery pipe is sealed to the side of the regulating valve box, the other end of the delivery pipe is sealed to the heat exchanger, a slot is opened in the top of the heat exchanger, and a heat exchange plate is clamped in the slot.

[0008] Preferably, a side door is rotatably connected to the side of the heat exchanger, and a door handle is fixed to the outer side of the side door.

[0016] 1.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, this embodiment proposes a circulating cooling furfural cooling tower, comprising a cooling tower body 1, a cooling fan 5 fixed on the top of the cooling tower body 1, a circulating water tank 4 fixed on the bottom of the cooling tower body 1, a descaling component 2 fixed on the side of the cooling tower body 1, and a cleaning component 3 fixed inside the cooling tower body 1;

[0027] The descaling assembly 2 includes a cleaning liquid tank 21, a connecting pipe 22 is sealedly connected to the side of the cleaning liquid tank 21, and the other end of the connecting pipe 22 is sealedly connected to the regulating valve box 23. A rotating column 25 is rotatably connected to the regulating valve box 23, a blocking valve 24 is fixed on the rotating column 25, and a rotating handle 26 is fixed on the top of the rotating column 25. A delivery pipe 212 is sealedly connected to the side of the regulating valve box 23, and the other end of the delivery pipe 212 is sealedly connected to the heat exchanger 27. A slot 28 is provided at the top of the heat exchanger 27, and a heat exchange plate 29 is fixed in the slot 28.

[0028] The side of the heat exchanger 27 is rotatably connected to a side door 210, and a door handle 211 is fixed to the outside of the side door 210;

[0029] A sealing strip is fixed to the inner wall edge of the side-opening door 210;

[0030] There are three groups of blocking valves 24, two groups of blocking valves 24 are symmetrically distributed in the rotating column 25, and the other group of blocking valves 24 is fixed in the middle;

[0031] The other end of the delivery pipe 212 is sealed and connected to the side of the cooling tower body 1 through the heat exchanger 27 .

[0032] In this embodiment, after the heat exchanger 27 has been used for a long time, scale will appear on the surface of the internal heat exchange plate 29, resulting in a reduction in its cooling effect. By rotating the handle 26, the blocking valve 24 inside the regulating valve box 23 is rotated to the side of the regulating valve box 23 close to the delivery pipe 212, so that the connecting pipe 22 can be connected to the heat exchanger 27. The suction pump inside the cleaning liquid tank 21 transmits the cleaning liquid to the heat exchanger 27 through the connecting pipe 22, so that not only the scale on the surface of the heat exchange plate 29 can be cleaned, but also the furfural attached to the inner wall of the pipe can be cleaned. The cleaning liquid has a cleaning effect on the surface of the heat exchange plate 29. When there is a lot of scale on the surface of the heat exchange plate 29 and the cleaning liquid cannot be completely cleaned, the side door 210 of the heat exchanger 27 can be opened, and the heat exchange plate 29 can be removed from the slot 28 and replaced. Regular inspection and maintenance can ensure that the heat exchanger 27 can maintain its cooling efficiency for a long time.

[0033] Example 2

[0034] like Figures 4 and 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a cleaning assembly 3 including a sliding groove 31, a servo motor 32 is fixed to the inner side of the sliding groove 31, a transmission screw 33 is fixed to the output end of the servo motor 32, a sliding block 34 is threadedly connected to the transmission screw 33, a support rod 35 is fixed to the side of the sliding block 34, a hydraulic rod 36 is fixed to the bottom of the support rod 35, a support plate 37 is fixed to the bottom of the hydraulic rod 36, and a cleaning brush 38 is fixed to the bottom of the support plate 37;

[0035] The sliding groove 31 is provided on the inner wall of the cooling tower body 1, and a sealed partition is provided between the transmission screw 33 and the servo motor 32;

[0036] The surface of the cleaning brush 38 is coated with a cleaning agent.

[0037] In this embodiment, after furfural is subjected to multiple cycles of cooling in the cooling tower body 1, due to the strong viscosity of furfural itself, furfural will adhere to the surface of the packing layer, and the scaling formed over a long period of time will clog the surface of the packing layer, resulting in reduced efficiency of the packing layer during the cycle cooling. The output end of the servo motor 32 drives the sliding block 34 to move threadedly in the transmission screw 33, so that the sliding block 34 located at the inner edge of the cooling tower body 1 moves toward the other end of the transmission screw 33, and the cleaning brush 38 at the bottom of the support rod 35 in the middle of the sliding block 34 is moved downward to the surface of the packing layer by the hydraulic rod 36, so that the cleaning brush 38 can clean the surface of the packing layer during the movement. The surface of the packing layer is cleaned regularly to prevent furfural from causing blockage in the packing layer after multiple cycles of cooling.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
