Description

Technical Field

[0001] This utility model relates to the field of chemical cooling equipment technology, and in particular to a circulating cooling device. Background Technology

[0002] Currently, large amounts of industrial wastewater are often generated, which causes great damage to the environment. For example, in chemical production, after cleaning products, material water with high salt content is generated. Then, the mother liquor is heated and evaporated through an MVR device to separate the salt and water. The salt is collected and packaged. The water after salt separation needs to undergo deep treatment, but the temperature of the separated water is too high, which is not conducive to deep wastewater treatment, and it is impossible to cool the high-temperature water for reuse.

[0003] A prior art patent with publication number CN222617656U discloses a closed-loop cooling tower for wastewater cooling, comprising a base plate, a cooling tower, and a wastewater tank, with cooling mechanisms installed inside both the cooling tower and the wastewater tank. A first pump pumps high-temperature wastewater into a U-shaped pipe. Since the bottom of the U-shaped pipe is submerged in cooling water, the cooling water directly cools the high-temperature wastewater. Simultaneously, a second pump pumps cooling water into a spray pipe, which is then sprayed out through multiple spray nozzles. The cold water sprayed from the spray nozzles cools the high-temperature wastewater. After absorbing heat from the high-temperature wastewater, the cooling water heats up. The pump then recirculates the heated cooling water into the spray pipe for spraying. However, this increased temperature reduces the heat exchange between the cooling water and the high-temperature wastewater, affecting subsequent heat exchange efficiency. Consequently, the cooling water recycling process may result in poor cooling effect on the high-temperature wastewater. Utility Model Content

[0004] This invention proposes a circulating cooling device that solves the problem of poor cooling effect of circulating cooling water on high-temperature sewage in the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A circulating cooling device includes a device body with a spray assembly and a sewage pipe. The spray pipe of the spray assembly is located above the sewage pipe, spraying cooling water onto the sewage pipe. A heat-absorbing assembly is located below the sewage pipe to absorb heat from the cooling water. The spray pipe cools the sewage pipe by spraying cooling water onto it. After absorbing heat from the sewage, the cooling water falls onto the heat-absorbing assembly, which absorbs the heat carried by the cooling water, further lowering its temperature. This allows the cooling water to better absorb heat from the sewage pipe when it sprays out again from the spray pipe, ensuring a consistent cooling effect.

[0007] The device body has a water collection tank at its bottom. The spray assembly includes a spray pump, the inlet of which is connected to the water collection tank, and the outlet of which is connected to the spray pipe. The water collection tank collects the cooling water sprayed from the spray pipe, and the spray pump pumps the cooling water from the water collection tank to the spray pipe, thus realizing the recycling of the cooling water.

[0008] The heat absorption assembly includes a coil with a medium outlet and a medium inlet extending out of the device body. Room temperature water flows through the coil; as the cooling water passes through the coil, the room temperature water absorbs heat from the cooling water, thus cooling it. The coil increases the contact area with the cooling water, improving the heat exchange efficiency between the cooling water and the coil. Both the inlet and outlet of the coil are located on the outside of the device body, facilitating the connection of external water pipes to the coil.

[0009] The coil is in contact with the sewage pipe. The room-temperature water inside the coil can also absorb the heat from the high-temperature sewage in the sewage pipe, improving the sewage cooling efficiency.

[0010] The coil is installed inside the water collection tank. The coil directly absorbs heat and cools the cooling water falling into the water collection tank, keeping the cooling water at a low temperature, thereby ensuring the cooling efficiency of the cooling water in cooling the high-temperature sewage in the sewage pipe.

[0011] The device body has a grille on its side, located above the water collection tank; the top of the device body has an opening, and a fan is installed at the top opening. When the fan is started, air enters the device body through the grille and then exits through the top opening. The airflow can simultaneously cool the sewage pipes and cooling water, ensuring a cooling effect on the high-temperature sewage in the sewage pipes.

[0012] The device contains a water collector located between the spray pipe and the fan. The water collector collects the water mist and directs it back into the collection tank.

[0013] The device body is equipped with a water replenishment component that communicates with the water collection tank. After the device has been used for a period of time, the cooling water evaporates and decreases. The water replenishment component replenishes the cooling water to prevent insufficient cooling water from causing low cooling efficiency.

[0014] The water replenishment component includes a water replenishment pipe that extends into the main body of the device. The water replenishment pipe is connected to a water source and is equipped with a float valve located in a water collection tank. The water source can be any one of a tap water pipe, a water tank, or a water reservoir. The float valve detects the water level in the water collection tank. When the water level in the water collection tank is low, the float valve opens, and the water replenishment pipe supplies water into the water collection tank.

[0015] The sewage pipeline includes multiple straight pipes, which are arranged at an angle within the device body. The straight pipes facilitate cleaning of the sewage pipeline, and the angled arrangement of the straight pipes helps to prevent impurities from accumulating and clogging the sewage pipeline.

[0016] The beneficial effects of this invention are as follows: the spray pipe sprays cooling water onto the sewage pipe to cool down the high-temperature sewage inside the sewage pipe. After absorbing the heat from the high-temperature sewage, the cooling water falls onto the heat absorption component, which absorbs the heat carried by the cooling water, thus lowering the temperature of the cooling water. This allows the cooling water to better absorb the heat from the sewage pipe when it sprays out of the spray pipe again, ensuring the cooling effect.

[0017] The inclined layout of sewage pipes facilitates cleaning, while the inclined layout of straight pipes can prevent impurities from accumulating and clogging the sewage pipes. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, as Figure 1As shown, a circulating cooling device includes a device body 1, on which a spray assembly 3 and a sewage pipe 4 are mounted. The spray pipe of the spray assembly 3 is located above the sewage pipe 4, spraying cooling water onto the sewage pipe 4. A heat-absorbing assembly 5 for absorbing heat from the cooling water is located below the sewage pipe 4. The device body 1 has a box structure, with the sewage pipe 4 located in the middle of the box structure. High-temperature sewage generated in chemical production flows into the sewage pipe 4. The cooling water sprayed from the spray pipe falls onto the sewage pipe 4, absorbing heat from the high-temperature sewage and increasing in temperature. The heat-absorbing assembly 5 then absorbs heat from the cooled water, lowering its temperature. This allows the cooled water to better absorb heat from the high-temperature sewage in the sewage pipe 4 when it sprays out again from the spray pipe, ensuring a cooling effect.

[0023] Furthermore, a water collection tank is provided at the bottom of the device body 1, and the spray assembly 3 includes a spray pump 31. The inlet of the spray pump 31 is connected to the water collection tank, and the outlet of the spray pump 31 is connected to the spray pipe. The lower part of the box structure is the water collection tank. The cooling water sprayed by the spray assembly 3 will fall into the water collection tank. The spray pump 31 can pump the cooling water in the water collection tank to the spray pipe, and then spray it out again from the spray pipe to realize the recycling of cooling water.

[0024] Furthermore, the heat absorption component 5 includes a coil with a medium outlet 51 and a medium inlet 52 extending out of the device body 1. Room temperature water flows through the coil. When cooling water passes through the coil, the room temperature water absorbs heat from the cooling water, thus cooling it down. The coil increases the contact area with the cooling water, improving the heat exchange efficiency between the cooling water and the coil. Both the inlet and outlet of the coil are located on the outside of the device body 1, facilitating the connection of external water pipes to the coil. In this embodiment, the coil is in contact with the sewage pipe 4. The room temperature water inside the coil can also absorb heat from the high-temperature sewage in the sewage pipe 4, improving the sewage cooling efficiency.

[0025] Example 2 differs from Example 1 in that the heat absorption component 5 includes a coil, which is installed inside the water collection tank. The coil directly absorbs heat from the cooling water falling into the water collection tank, keeping the cooling water at a low temperature, thereby ensuring the cooling efficiency of the cooling water in cooling the high-temperature sewage in the sewage pipe 4.

[0026] Example 3, based on Example 1, provides a circulating cooling device. The device body 1 has a grid 11 on its side, located above the water collection tank. The top of the device body 1 has an opening, and a fan is located at the top opening. Specifically, the device body 1 has grids 11 on both its left and right sides. The fan includes a motor 7 located at the top opening of the device body 1. The output end of the motor 7 has blades 8. The motor 7 drives the blades 8 to rotate, causing airflow. Air enters the device body 1 through the grids 11 and then exits through the top opening. During this airflow, the sewage pipe 4 is cooled, improving cooling efficiency.

[0027] Furthermore, a water collector 2 is installed inside the main body 1, located between the spray pipe and the fan. The water collector collects the water mist and causes it to fall back into the water collection tank.

[0028] Furthermore, the device body 1 is equipped with a water replenishment component 6 that communicates with the water collection tank. After the device has been used for a period of time, the cooling water evaporates and decreases. The water replenishment component 6 replenishes the cooling water to prevent insufficient cooling water from causing low cooling efficiency. The water replenishment component 6 includes a water replenishment pipe that extends into the device body 1 and is connected to a water source. A float valve located in the water collection tank is installed on the water replenishment pipe. The water source can be any one of a tap water pipe, a water tank, or a water reservoir. In this embodiment, the water source is a tap water pipe. The float valve monitors the water level in the water collection tank in real time. When the water level in the water collection tank is low, the float valve opens, and the water replenishment pipe introduces water into the water collection tank.

[0029] Furthermore, the sewage pipe 4 includes multiple straight pipes, which are arranged at an angle within the device body 1. The multiple straight pipes are arranged side by side at an angle, with both ends of the straight pipes extending out of the device body 1. The upper end of the straight pipe is provided with a sewage inlet 41, and the lower end of the straight pipe is provided with a sewage outlet 42. The angled arrangement of the straight pipes facilitates the cleaning of the sewage pipes, and at the same time, the angled arrangement of the straight pipes can prevent the accumulation and blockage of impurities in the sewage pipes.
