Description

Technical Field

[0001] The utility model relates to the technical field of coal chemical industry, in particular to a coal chemical industry cooling device. Background Art

[0002] Coal chemical cooling equipment is a key equipment used to reduce the temperature of materials or equipment in the coal chemical production process. In coal chemical production, due to the existence of high-temperature reactions, cooling equipment is required to reduce the temperature of materials or equipment to a level that is safe or required by the process. The design and efficiency of cooling equipment directly affect the safety, stability and economic benefits of the entire production process;

[0003] The utility model with application number 202220378762.5 discloses a coal chemical cooling device. The cooling water circulation effect is achieved by the coordinated use of a cold water tank, a heat exchange tube, a water inlet pipe, a water pump, a water pump and a circulation pipe. The cooling water absorbs the heat in the high-temperature gas in the cooling box during the circulation inside the heat exchange tube, thereby achieving the effect of cooling the gas. At the same time, when the high-temperature gas enters the cooling box, the heat conduction plate can absorb the heat of the high-temperature gas, and finally the heat absorbed by the heat conduction plate is dissipated to the outside of the cooling box through a plurality of heat dissipation fins. The fan blades are driven to rotate by a driving motor, and the fan blades can perform air cooling and heat dissipation on the heat dissipation fins, thereby accelerating the efficiency of heat dissipation inside the cooling box and improving the cooling effect of the device. The locking universal wheels are arranged to facilitate the overall movement of the device, and the push rods are arranged to facilitate the staff to push the device to move, so that the device is easy to install and transport, and the portability of the device is improved.

[0004] However, in the above-mentioned coal chemical cooling device, the contact area between the heat exchange tubes and the heat conduction plates and the high-temperature coal chemical gas in the cooling box is small, and heat exchange cannot be absorbed quickly. When the water in the heat exchange tubes is pumped and circulated by a water pump and a pumping pipe in the above-mentioned coal chemical cooling device, the water temperature in the heat exchange tubes is relatively high after contacting the high-temperature coal chemical gas. If the water is directly pumped into the water pump for a long time, it is easy to cause damage to the water pump and affect the cooling work. Therefore, the utility model proposes a coal chemical cooling equipment to solve the problems existing in the prior art. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to propose a coal chemical cooling equipment, which fully increases the heat absorption and heat dissipation area by arranging and fixing heat-absorbing fins and cooling fins on the inside and outside of the heat conduction plate respectively, so as to facilitate the rapid absorption of high-temperature gas from the coal chemical industry in the cooling box and quickly conduct heat and dissipate heat, thereby solving the problem that the contact area between the heat exchange tube and the heat conduction plate and the high-temperature gas is small and cannot quickly absorb heat and exchange heat. The cold water in the water tank is pumped by a water pump for circulation to avoid damage to the water pump caused by contact with hot water. At the same time, a heat dissipation sleeve is installed on the outer sleeve of the circulating water pipe to absorb the heat of the hot water and dissipate the heat in advance, thereby solving the problem that hot water directly pumped into the water pump may easily cause damage to the water pump.

[0006] To achieve the purpose of the utility model, the utility model is implemented through the following technical solutions: a coal chemical cooling equipment, including a cooling box, a water tank, a water-cooled heat conduction mechanism, a heat dissipation cooling mechanism and a cooling water circulation mechanism, a water tank is arranged next to one side of the cooling box, the water-cooled heat conduction mechanism includes a heat conduction plate, heat absorption fins, a cooling water tank and cooling fins, a heat conduction plate is fixedly arranged around the cooling box, heat absorption fins are arranged and fixedly arranged on the inner side of the heat conduction plate, a cooling water tank is fixedly arranged around the outer side of the cooling box, cooling fins are fixedly arranged on the outer side of the heat conduction plate, a heat dissipation cooling mechanism is arranged in the water tank, and a cooling water circulation mechanism is arranged on the other side of the water tank.

[0012] A further improvement is that an air outlet pipe is connected to one side of the cooling box, and an air inlet pipe is connected to the lower side of the other side of the cooling box, and an opening and closing valve is fixedly installed on the air inlet pipe.

[0013] The beneficial effects of the utility model are as follows: the utility model arranges and fixes heat-absorbing fins and cooling fins on the inner and outer sides of the heat-conducting plate respectively, thereby fully increasing the heat-absorbing and heat-dissipating area, facilitating and quickly absorbing the high-temperature gas of the coal chemical industry in the cooling box and quickly dissipating the heat, solving the problem that the contact area between the heat exchange tube and the heat-conducting plate and the high-temperature gas is small and cannot quickly absorb and exchange heat.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , Figure 2 , Figure 3 As shown, the present embodiment provides a coal chemical cooling device, including a cooling box 1, a water tank 2, a water-cooled heat conduction mechanism, a heat dissipation cooling mechanism and a cooling water circulation mechanism. A water tank 2 is arranged next to one side of the cooling box 1. The water-cooled heat conduction mechanism includes a heat conduction plate 3, a heat absorption fin 4, a cooling water tank 5 and a cooling fin 6. A heat conduction plate 3 is fixedly arranged around the cooling box 1, and a heat absorption fin 4 is arranged and fixed on the inner side of the heat conduction plate 3. A cooling water tank 5 is fixedly arranged around the outer side of the cooling box 1, and a cooling fin 6 is fixedly arranged on the outer side of the heat conduction plate 3. When cooling, the heat absorption fin 4 is used to increase the heat absorption area, quickly absorb the heat of the high-temperature gas introduced into the cooling box 1 and transfer the heat to the cooling fin 6 through the heat conduction plate 3. Multiple groups of cooling fins 6 also increase the heat dissipation cooling area and accelerate the cooling speed, solving the problem that the heat exchange tube 8 and the heat conduction plate 3 have a small contact area with the high-temperature gas of the coal chemical industry in the cooling box 1 and cannot quickly absorb heat exchange. A heat dissipation cooling mechanism is arranged in the water tank 2, and a cooling water circulation mechanism is arranged on the other side of the water tank 2.

[0020] The heat dissipation cooling mechanism includes a box cover 7, a heat pipe 8, a thermal fin 9 and a fan 10. The water tank 2 is provided with a box cover 7 on which heat pipes 8 are arranged and fixedly provided. Thermal fins 9 are arranged and fixedly provided at the upper ends of the heat pipes 8. A fan 10 is fixedly provided on one side of the water tank 2. There are multiple groups of heat pipes 8 and the lower ends of the heat pipes 8 extend into the bottom of the water tank 2. The height positions of the fan 10 and the thermal fins 9 correspond. A coolant is provided in the hollow of the heat pipe 8. When hot water circulates into the water tank 2, the lower ends of the heat pipes 8 quickly absorb heat and transfer heat upward. The thermal fins 9 increase the heat dissipation area. Turning on the fan 10 for blowing increases the air flow rate and improves the heat dissipation speed, thereby effectively reducing the water temperature.

[0021] The cooling water circulation mechanism includes a water pump 11, a water delivery pipe 12, a circulating water pipe 13 and a heat dissipation sleeve 14. The water pump 11 is fixedly provided on the other side of the water tank 2. The water pump 11 is connected to the water tank 2 through a water delivery pipe 12. A circulating water pipe 13 is connected to the water tank 2 on one side below the cooling water tank 5. The circulating water pipe 13 is sleeved with a heat dissipation sleeve 14. When water is delivered, the water pump 11 is started to deliver the water in the water tank 2 to the cooling water tank 5 through the water delivery pipe 12 to replace the hot water inside. The hot water circulates back into the water tank 2 through the circulating water pipe 13, so that the temperature of the water pumped by the water pump 11 is relatively low, and the hot water refluxes through the circulating water pipe 13 and simultaneously passes through the heat dissipation sleeve 14 for preliminary heat dissipation and cooling in advance.

[0022] The upper end of the water delivery pipe 12 is connected to the upper side of the other side of the cooling water tank 5, the inner wall of the heat dissipation sleeve 14 is tightly fitted with the circulating water pipe 13, and the heat dissipation fins 15 are arranged and fixed outside the heat dissipation sleeve 14. After the heat dissipation sleeve 14 absorbs heat, the heat dissipation fins 15 increase the heat dissipation area to dissipate heat and cool down.

[0023] An outlet pipe 16 is connected to one side of the cooling box 1, and an inlet pipe 17 is connected to the lower side of the other side of the cooling box 1. An opening and closing valve 18 is fixedly installed on the inlet pipe 17. The opening and closing valve 18 is opened when the gas is transported. When cooling is performed, the high-temperature gas from the coal chemical industry enters the cooling box 1 through the inlet pipe 17, and is discharged from the outlet pipe 16 after cooling and heat dissipation.

[0024] When the coal chemical cooling equipment is working, the on-off valve is opened to pass the high-temperature gas from the coal chemical industry into the cooling box through the air inlet pipe, the heat-absorbing fins fully absorb the heat of the high-temperature gas and quickly transfer the heat to the cooling fins through the heat-conducting plate, and the cooling fins contact the water in the cooling water tank to quickly cool down, and the large contact area between the heat-absorbing fins and the cooling fins is utilized to quickly cool down, and the cooled gas is discharged from the air outlet pipe, and the hot water enters the water tank through the circulating water pipe. At the same time, the heat dissipation sleeve is sleeved outside the circulating water pipe and the hot water is initially dissipated by the heat sink. At the same time, the water pump is started to pump the cold water in the water tank into the cooling water tank through the water pipe to replace the hot water that has heated up after absorbing the heat of the cooling fins. The hot water flows back into the water tank through the circulating water pipe. When the water temperature in the water tank rises, the heat is absorbed by the lower end of the heat pipe and transferred upward to the heat-conducting fins, and the fan is started to blow air to cool the heat-conducting fins.

[0025] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
