Description

Technical Field

[0001] This utility model belongs to the technical field of cooling equipment, specifically relating to a compressed air cooling device for chemical production. Background Technology

[0002] In the chemical production industry, air compressors are commonly used to produce compressed air for use in production equipment. Furthermore, chemical production is a highly precise process, and compressed air often comes into direct contact with products or process media. Some processes have strict requirements on the inlet temperature of the compressed air. Since the compressed gas produced by the compressor is at a relatively high temperature, it needs to be cooled before use. Currently, compressed air cooling is typically achieved through air cooling or water cooling. Water cooling usually involves placing the compressed air pipeline inside the water tank and supplying a cryogenic liquid to cool the compressed air. However, currently, the cryogenic liquid inside the water tank is usually prepared using a condenser, which requires continuous operation during use, resulting in high energy consumption and a relatively simple operating method. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a compressed air cooling device for chemical production, comprising: Water storage tank; A cooling box is installed on top of the water storage tank. An overflow pipe is connected to the middle of the cooling box along the height direction. The overflow pipe is connected to the water storage tank. A water pump for pumping coolant into the cooling box is also connected to the bottom of the water storage tank. An air supply pipe is installed inside the cooling box and located below the overflow pipe for circulating compressed air. A fan is installed above the cooling box to blow cold air into the cooling box. A cooling fin is also installed above the fan.

[0005] In one possible implementation, a spray pipe is also installed on the top of the cooling box, the spray pipe is located below the cooling element, and the spray pipe is connected to the outlet of the water pump.

[0006] In one possible implementation, the spray pipe includes: The horizontal water pipe is connected in the middle to the outlet pipe of the water pump; There are multiple longitudinal water pipes, which are arranged at intervals along the length of the transverse water pipe and are all connected to the transverse water pipe.

[0007] In one possible implementation, a mounting frame is installed on the upper part of the cooling box, and multiple fans are evenly distributed on the mounting frame, with each fan having an individually controllable cooling plate mounted above it.

[0008] In one possible implementation, the spray pipe is mounted on the bracket, and the position of the spray pipe on the bracket has a degree of freedom to be adjusted in the vertical direction.

[0009] In one possible implementation, a screw rod arranged vertically is fixedly installed on the spray pipe, the fixing frame is provided with mounting holes for installing the screw rod, and the screw rod is threadedly connected to two fixing members for abutting against the upper and lower sides of the fixing frame respectively.

[0010] In one possible implementation, the gas pipeline includes: Intake pipe; The exhaust pipe is arranged parallel to the intake pipe at a distance; There are multiple diverter pipes, which are arranged parallel to each other at intervals along the length of the intake pipe, and both ends of the diverter pipe are respectively connected to the intake pipe and the outlet pipe.

[0011] In one possible implementation, the air inlet end of the air inlet pipe is located at one end of the air inlet pipe, the air outlet end of the air outlet pipe is located at one end of the air outlet pipe, and the air inlet end of the air inlet pipe and the air outlet end of the air outlet pipe are located on both sides of the split pipe along the arrangement direction of the plurality of split pipes.

[0012] In one possible implementation, the cooling box is further fixedly mounted with a mounting bracket for mounting the fixed frame.

[0014] The solution shown in this application, compared with the prior art, incorporates a water storage tank with a cooling chamber installed above it. An air supply pipe is installed inside the cooling chamber, allowing compressed air to enter and exit from one end of the pipe. An overflow pipe connects to the middle of the cooling chamber, with the air supply pipe located below it, ensuring the pipe remains below the liquid level for cooling the compressed air. This application also includes a fan installed above the cooling chamber, blowing air into it. A cooling fin is positioned above the fan and connected to the cooling end of a condenser. The condenser supplies cold air to the cooling fin. In applications with high ambient temperatures, the condenser can be opened to lower the temperature of the cooling fin, and the fan delivers low-temperature gas into the cooling chamber to cool the coolant.

Furthermore, when the external environment allows the cooling chamber's internal temperature to recover naturally, the fan can be turned off, and the coolant can circulate solely through the water pump. This application allows for adjustments to different operating modes based on the external temperature, thus achieving energy conservation and consumption reduction. Attached Figure Description

[0016] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Please refer to the following: Figures 1 to 3The compressed air cooling device for chemical production provided by this utility model is described below. The compressed air cooling device for chemical production includes a water tank 1, a cooling chamber 2, an air supply pipe 3, and a fan 4. The cooling chamber 2 is installed on top of the water tank 1. An overflow pipe 21 is connected to the middle of the cooling chamber 2 along its height direction, and the overflow pipe 21 is connected to the water tank 1. A water pump for pumping coolant into the cooling chamber 2 is also connected to the bottom of the water tank 1. The air supply pipe 3 is installed inside the cooling chamber 2 and below the overflow pipe 21, for circulating compressed air. The fan 4 is installed above the cooling chamber 2 for blowing cold air into the cooling chamber 2. A cooling fin 5 is also installed above the fan 4.

[0018] The compressed air cooling device for chemical production provided in this embodiment, compared with the prior art, features a water storage tank 1, with a cooling tank 2 installed above it. An air supply pipe 3 is installed inside the cooling tank 2. Compressed air is supplied from one end of the air supply pipe 3 into the pipe and output from the other end. An overflow pipe 21 is connected to the middle of the cooling tank 2, and the air supply pipe 3 is located below it, ensuring that the air supply pipe 3 remains below the liquid surface for cooling the compressed air. A fan 4 is installed above the cooling tank 2, blowing air into it. A cooling element 5 is positioned above the fan 4 and connected to the cooling end of a condenser. The condenser supplies a cold source to the cooling element 5. In cases of high ambient temperature, the condenser can be opened to lower the temperature of the cooling element 5, and the fan 4 delivers low-temperature gas into the cooling tank 2, thus cooling the coolant inside. When the ambient temperature is low, the condenser can be shut off, and fan 4 will blow cool outside air into the cooling chamber 2 to cool the coolant. Furthermore, when the ambient temperature is sufficient for the cooling chamber 2 to recover its internal temperature, fan 4 can be shut off, and the coolant can circulate independently using only the water pump. This application allows for adjustments to different operating modes based on the ambient temperature, thus achieving energy savings and reduced consumption.

[0019] Specifically, in this embodiment, a drain pipe is connected to the bottom of the cooling box 2, and a control valve for controlling the flow state is installed on the drain pipe to facilitate the later emptying and cleaning of the interior of the cooling box 2.

[0020] In some embodiments, the cooling box 2 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2The top of the cooling box 2 is also equipped with a spray pipe 6, which is located below the cooling element 5 and is connected to the outlet of the water pump. The top of the cooling box 2 has an open structure, and the spray pipe 6 is installed at the opening of the cooling box 2. Multiple nozzles are installed on the spray pipe 6. The coolant inside the water tank 1 is pumped into the spray pipe 6 by the water pump and sprayed into the cooling box 2 through the spray pipe 6. When the coolant level inside the cooling box 2 reaches the overflow pipe 21, it flows back into the water tank 1 through the overflow pipe 21, forming a coolant circulation. In this embodiment, the spray pipe 6 allows the coolant to be dispersed and fall into the cooling box 2 when it is pumped in, enabling more effective heat dissipation through the cold air brought by the fan 4 and improving heat dissipation efficiency.

[0021] In some embodiments, the spray pipe 6 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The spray pipe 6 includes horizontal water pipes 61 and vertical water pipes 62. The middle of the horizontal water pipe 61 is connected to the outlet pipe of the water pump. Multiple vertical water pipes 62 are arranged sequentially and spaced apart along the length of the horizontal water pipe 61, and all are connected to the horizontal water pipe 61. Specifically, in this embodiment, there are two horizontal water pipes 61, both ends of which are closed. The two ends of the vertical water pipe 62 are connected to the two horizontal water pipes 61, and one of the horizontal water pipes 61 is connected to the outlet of the water pump. When the spray pipe 6 is installed at the opening of the cooling box 2, multiple spray holes are provided on the bottom side of the vertical water pipe 62, and these spray holes are evenly spaced along the length of the vertical water pipe 62. This effectively disperses the coolant pumped into the vertical water pipe 62, improving heat dissipation efficiency.

[0022] Specifically, in this embodiment, a filter screen is also installed at the inlet end of the water pump, so as to prevent external impurities from being pumped into the spray pipe 6 and clogging the spray holes on the longitudinal water pipe 62.

[0023] Preferably, in this embodiment, the design of two horizontal water pipes 61 can improve the stability of the installation position of the vertical water pipe 62. The two horizontal water pipes 61 can be used to fix the pipe to the cooling box 2.

[0024] In some embodiments, the cooling box 2 described above can be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The cooling chamber 2 has a mounting frame 7 on its upper part. Multiple fans 4 are evenly distributed on the mounting frame 7, and each fan 4 has a corresponding individually controllable cooling plate 5 mounted above it. The mounting frame 7 is divided into multiple cooling zones by partitions. Each cooling zone has its own fan 4 and a corresponding cooling plate 5. Each cooling plate 5 has a flow regulating valve at its inlet end, which controls the flow rate of the cooling medium supplied from the condenser to the cooling plate 5. This allows for control of the operating status of individual cooling zones based on the on-site operating environment.

[0025] Preferably, in this embodiment, the cooling chip 5 includes multiple heat sinks arranged in parallel. In this application, the cooling effect can be adjusted by turning on the cooling chip 5 and the corresponding number of fans 4.

[0026] In some embodiments, the spray pipe 6 can be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The spray pipe 6 is mounted on the fixed frame 7, and its position on the fixed frame 7 has a degree of freedom for vertical adjustment. The spray pipe 6 is fixedly mounted on the bottom of the fixed frame 7 and is spaced apart from the fixed frame 7 in the vertical direction. This allows the fan 4 on the fixed frame 7 to effectively apply cold air to the spray pipe 6 and the coolant sprayed from the spray pipe 6, enabling the coolant to be effectively cooled and heat exchanged.

[0027] Specifically, in this embodiment, the distance between the spray pipe 6 and the fixing frame 7 is adjustable. During the debugging process, the distance between the spray pipe 6 and the fixing frame 7 can be adjusted according to the state of the coolant sprayed from the spray pipe 6 and the cooling effect. This ensures stable cooling while maintaining a stable spraying effect from the spray pipe 6.

[0028] In some embodiments, the spray pipe 6 can be adopted as follows: Figure 3 The structure shown. See also Figure 3A vertically oriented screw 63 is fixedly installed on the spray pipe 6. The mounting bracket 7 has mounting holes for the screw 63, and two fasteners 64 are threaded onto the screw 63, respectively abutting against the upper and lower sides of the mounting bracket 7. Two support plates are fixedly installed between the two horizontal water pipes 61 on the spray pipe 6, each fixed at one end of the two horizontal water pipes 61. A screw 63 is fixedly installed on the support plate, vertically oriented and passing through the mounting holes on the mounting bracket 7. Each screw 63 is threaded with a fastener 64, which abuts against the upper and lower sides of the mounting bracket 7, clamping the mounting bracket 7 between the two corresponding fasteners 64, thus connecting the spray pipe 6 to the mounting bracket 7.

[0029] Preferably, in this embodiment, the spray pipe 6 has four screws 63, which are respectively installed at the four corners of the fixing frame 7. When it is necessary to adjust the spacing between the spray pipes 6, the position of the corresponding fixing member 64 on the four screws 63 can be adjusted to adjust the height of the spray pipe 6. At the same time, the fixing frame 7 is fixedly installed on the cooling box 2. By adjusting the relative position between the spray pipe 6 and the fixing frame 7, the height of the spray pipe 6 inside the cooling box 2 can be adjusted simultaneously, so that the spray pipe 6 and the liquid level inside the cooling box 2 are kept at a certain height, thus maintaining a certain spraying effect.

[0030] In some embodiments, the gas pipeline 3 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The air supply pipe 3 includes an inlet pipe 31, an outlet pipe 32, and branch pipes 33. The outlet pipe 32 is arranged parallel to the inlet pipe 31 at intervals. Multiple branch pipes 33 are arranged parallel to each other at intervals along the length of the inlet pipe 31, and both ends of each branch pipe 33 are connected to the inlet pipe 31 and the outlet pipe 32, respectively. The inlet pipe 31 and the outlet pipe 32 are arranged parallel to each other at intervals, and multiple branch pipes 33 are connected between the inlet pipe 31 and the outlet pipe 32. The inner diameter of each branch pipe 33 is smaller than the outer diameter of the inlet pipe 31 and the outlet pipe 32. The outlet end of the air compressor is connected to the inlet pipe 31, and the air is distributed through the inlet pipe 31 into the multiple branch pipes 33, finally being discharged through the outlet pipe 32.

[0031] Specifically, multiple diversion pipes 33 are installed in parallel between the intake pipe 31 and the outlet pipe 32 at intervals. By setting up the diversion pipes 33, the gas entering the intake pipe 31 can be diverted into the multiple diversion pipes 33, thereby increasing the heat dissipation area and improving the heat dissipation effect.

[0032] Preferably, in this embodiment, after the gas supply pipe 3 is installed inside the cooling box 2, the inlet pipe 31 and the outlet pipe 32 both abut against the bottom of the cooling box 2, while multiple diversion pipes 33 are suspended inside the cooling box 2, so that the periphery of the diversion pipes 33 can be effectively heat exchanged, thereby improving the heat exchange effect.

[0033] In some embodiments, the gas pipeline 3 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The intake end of the intake pipe 31 is located at one end of the intake pipe 31, and the outlet end of the outlet pipe 32 is located at one end of the outlet pipe 32. The intake end of the intake pipe 31 and the outlet end of the outlet pipe 32 are located on both sides of the multiple branch pipes 33 along the arrangement direction of the branch pipes 33. The intake pipe 31 and the outlet pipe 32 are of the same length, and their ends are flush. Both ends of the intake pipe 31 and the outlet pipe 32 are closed structures, with an intake end connected to the intake pipe 31 and an outlet end connected to the outlet pipe 32. Compressed gas enters the intake pipe 31 through the intake end and is discharged through the outlet end of the outlet pipe 32. The arrangement direction of the multiple split pipes 33 is defined as the first direction. The multiple split pipes 33 are located between the air inlet end on the air inlet pipe 31 and the air outlet end on the air outlet pipe 32 along the first direction, so that the compressed air entering the air inlet pipe 31 can be effectively distributed to the multiple split pipes 33, thereby achieving an effective heat exchange effect.

[0034] In some embodiments, the aforementioned fixing bracket 7 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The cooling box 2 is also fixedly mounted with a mounting frame 8 for mounting the fixing frame 7. The mounting frame 8 includes multiple columns located on the outside of the fixing frame 7. Support arms 81 for supporting the fixing frame 7 are mounted on the columns. A pressure plate 82 for pressing the fixing frame 7 onto the support arms 81 is detachably mounted on the top of the support arms 81. The mounting frame 8 is fixedly mounted on the ground, and the cooling box 2 is fixedly mounted in the middle of the mounting frame 8. Multiple columns are fixedly mounted on the top of the mounting frame 8, and support arms 81 are mounted on the columns. The support arms 81 extend into the mounting frame 8, so that when installing the fixing frame 7, the fixing frame 7 can be overlapped onto the support arms 81. Finally, the pressure plate 82 presses the fixing frame 7 onto the support arms 81, thus fixing the fixing frame 7 on the mounting frame 8.

[0035] Preferably, in this embodiment, a support arm 81 is slidably mounted on the column, and a tightening member for abutting against the column is threaded onto the side wall of the support arm 81, thereby fixing the support arm 81 to the column. Simultaneously, a support ring for supporting the support arm 81 is welded onto the column. In practical application, the positions of the support arms 81 on each column can be adjusted first, so that the fixing frame 7 can effectively abut against multiple support arms 81. Finally, the support ring is abutted against the bottom side of the support arm 81, and welded to the column, providing stability for the position of the support arm 81.

[0036] In some embodiments, the pressure plate 82 may be as follows: Figure 3 The structure shown. See also Figure 3 The pressure plate 82 is slidably mounted on the column, and a vertical rod 83 is fixedly installed on the support arm 81. The vertical rod 83 passes through the pressure plate 82, and a fastener 84 is threaded onto the vertical rod 83 to abut against the top surface of the pressure plate 82. The vertical rod 83 is fixedly installed in the middle of the support arm 81. The vertical rod 83 is a screw 63. The pressure plate 82 has a through hole for installing the vertical rod 83. The vertical rod 83 is located inside the through hole. The fastener 84 is a nut. By rotating the fastener 84, the fastener 84 can abut against the outer surface of the pressure plate 82, thereby pressing the pressure plate 82 against the top of the fixing frame 7, thus fixing the fixing frame 7. In addition, when it is necessary to maintain the fan 4 or the cooling element 5 in the future, the fixing frame 7 can be easily removed from the cooling box 2, which facilitates the maintenance of the entire refrigeration system.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
