Description

Technical Field

[0001] The utility model relates to the technical field of circulating water cooling, in particular to a multi-purpose cooling treatment system. Background Art

[0002] In workshop production, a multi-purpose cooling treatment system uses an open cooling tower heat exchanger to cool the chilled water system in winter using the low ambient temperature below 10°C, reducing the load of the refrigeration machine and reducing power consumption. In summer, the steam condensate is cooled and recycled to the desalted water system to reduce water consumption.

[0003] However, the existing devices have the following problems: Problems with the chilled water system: The ambient temperature is low in winter, and the low ambient temperature can be used to cool the chilled water. The use of an open cooling tower will affect the quality of the chilled water, and the existing devices have low heat exchange efficiency; and the steam condensate system, due to the high temperature in summer, the boiler system cannot be fully recycled and reused, and is directly discharged, resulting in waste. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a multi-purpose cooling treatment system. By setting up an induced ventilation closed cooling tower and a heat exchanger, the influence of the external environment on the quality of chilled water is avoided. By setting up a spray plate and an induced draft fan, the water pipes inside the cooling tower are intermittently sprayed to dissipate heat and remove impurities. The holes on the walls of the induced ventilation closed cooling tower are used for air entry, which greatly improves the heat exchange efficiency. By setting up a desalted water tank, excess steam condensate is collected and reused, which greatly saves production costs and avoids waste.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The multi-purpose cooling treatment system includes a chilled water supply pump, which is connected to a chilled water pool through a heat exchanger, and the heat exchanger is connected to an intermediate water tank through an intermediate water tank inlet pipe. The intermediate water tank is connected to an induced ventilation closed cooling tower through a circulating water pump. The interior of the induced ventilation closed cooling tower is provided with a cooling tower internal water pipeline, and a spray plate is provided on the cooling tower internal water pipeline.

[0007] There are vents on the vertical wall of the induced draft closed cooling tower. The induced draft closed cooling tower means that the outer wall can be connected to the outside world, and the water pipes inside the cooling tower are not connected to the outside air. The water pipes inside the cooling tower will be deposited on the surface of the water pipes inside the cooling tower over time due to the presence of a lot of dust in the external environment. By introducing the water in the intermediate water tank into the spray plate, the heat exchanger coils are intermittently flushed to improve the heat exchange efficiency.

[0008] A heat exchanger coil inlet pipe is connected between the chilled water supply pump and the heat exchanger, a steam condensate pump is connected to the heat exchanger coil inlet pipe, and a steam condensate pump outlet pipe is provided between the steam condensate pump and the heat exchanger coil inlet pipe.

[0009] The circulating water pump is connected to the spray plate through a spray pipe, the spray pipe is made of metal, and no insulation device is arranged outside the spray pipe. A cooling tower inlet pipe is arranged between the circulating water pump and the induced ventilation closed cooling tower.

[0010] The inner water pipeline of the cooling tower is connected with a water outlet pipeline, and the water outlet pipeline is connected with the heat exchanger.

[0011] A water outlet is arranged at the bottom of the cooling tower, and an induced draft fan is connected to the vertical wall of the induced ventilation closed cooling tower.

[0012] The heat exchanger is connected to the desalted water tank through a heat exchanger outlet pipe, and a freezing water tank inlet pipe is connected between the heat exchanger outlet pipe and the freezing water tank.

[0013] The chilled water supply pump is connected to the chilled water tank through a heat exchanger, the steam condensate pump is connected to the desalted water tank through a heat exchanger, the heat exchanger is connected to the induced ventilation closed cooling tower through an intermediate water tank, the induced ventilation closed cooling tower is connected to the heat exchanger through a water outlet pipe, and a pipe connecting to the outside is provided on the water outlet pipe.

[0014] The working principle of the utility model is:

[0015] After the chilled water supply pump is started, the chilled water enters the heat exchanger through the heat exchanger coil pipe, and enters the chilled water tank after the heat exchange is completed; after the steam condensate pump supply pump is started, the steam condensate enters the heat exchanger through the heat exchanger coil pipe, and enters the demineralized water tank after the heat exchange is completed; the liquid phase in the induced ventilation closed cooling tower enters the heat exchanger through the outlet pipe, and returns to the induced ventilation closed cooling tower through the intermediate water tank after the heat exchange is completed, and the induced draft fan is started; the water pipes inside the cooling tower, due to the presence of a lot of dust in the external environment, will be deposited on the surface of the water pipes inside the cooling tower over time. By introducing the water in the intermediate water tank into the spray plate, the water pipes inside the cooling tower can be intermittently flushed to improve the heat exchange efficiency.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By adopting the multi-purpose temperature reduction treatment system of the utility model, the influence of the external environment on the quality of the chilled water is avoided through the arrangement of the induced ventilation closed cooling tower and the heat exchanger. The spray plate and the induced draft fan are arranged to intermittently spray the water pipe inside the cooling tower to dissipate heat and remove impurities. The holes on the vertical wall of the induced ventilation closed cooling tower are used for the entry of air, which greatly improves the heat exchange efficiency. By setting the desalted water tank, the excess steam condensate is collected and reused, which greatly saves the production cost and avoids waste. BRIEF DESCRIPTION OF THE DRAWINGS
