Heat exchange device for temperature adjustment of compressor outlet material

Abstract

This utility model relates to the field of industrial fluid temperature control equipment, specifically to a heat exchange device for regulating the temperature of materials at the compressor outlet. It includes a housing, a connecting pipe on the left side of the housing, a mounting flange at one end of the connecting pipe, and a mounting mechanism fixedly connected to the outer surface of the connecting pipe. This utility model utilizes the synergistic action of a drive assembly and a descaling assembly. When the motor drives the lead screw in both forward and reverse directions, the threaded block drives the push block to move horizontally, thereby pushing the fixed ring and the annular scraper to slide reciprocally along the surface of the heat exchange tube. The annular scraper can remove the scale layer on the inner wall of the heat exchange tube in real time, preventing scale accumulation from reducing heat exchange efficiency and ensuring long-term stable temperature control. Simultaneously, it eliminates the need for manual cleaning during downtime, reducing maintenance costs and downtime losses. Furthermore, the movement of the threaded block, push block, and descaling assembly causes the cooling water inside the housing to slosh, improving the uniformity of contact between the cooling water and the heat exchange tube, further enhancing the utilization rate of the cooling water.

Description

Technical Field

[0001] This utility model relates to the field of industrial fluid temperature control equipment, specifically to a heat exchange device for adjusting the temperature of materials at the compressor outlet. Background Technology

[0002] In industrial production processes, compressors, as core equipment for fluid pressurization, cause a significant temperature increase in the outlet material (such as air, refrigerant, and chemical raw materials) during operation due to mechanical compression, typically reaching 80-150℃. Subsequent processes (such as gas transportation, material reaction, and product cooling) have strict temperature limits on the materials. For example, some reactions in the chemical industry require material temperatures to be controlled between 30-50℃. If high-temperature materials directly enter subsequent stages, it will not only disrupt process stability and reduce product quality, but may also cause damage to pipelines, valves, and other equipment due to thermal stress, while also resulting in significant energy waste and increased energy costs for enterprises. Therefore, efficient temperature control of the compressor outlet material has become a crucial step in ensuring continuous production and reducing energy consumption.

[0003] Currently, the industry generally uses traditional shell-and-tube heat exchangers to regulate the temperature of the compressor outlet material. This is achieved by exchanging heat between the shell-side cooling water and the high-temperature material in the tubes. However, these devices have significant technical shortcomings. After long-term use, scale easily forms on the outer wall of the heat exchange tubes, leading to a decrease in the heat transfer coefficient and a significant reduction in temperature regulation efficiency. Regular shutdowns for manual cleaning are required, increasing maintenance costs and downtime losses. In addition, the existing devices rely on a single flange for connection to the compressor outlet pipeline. Since the compressor is vibrating during operation, the connection is prone to instability, leading to material leakage.

[0004] Therefore, it is necessary to invent a heat exchange device for regulating the temperature of the material at the compressor outlet to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat exchange device for regulating the temperature of materials at the compressor outlet. By using a descaling component, the device automatically removes scale buildup on the heat exchange tubes, thereby solving the problem of reduced temperature regulation efficiency caused by easy scaling on the heat exchange tubes in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat exchange device for regulating the temperature of materials at the compressor outlet, comprising a housing, a connecting pipe on the left side of the housing, a mounting flange at one end of the connecting pipe, an installation mechanism fixedly connected to the outer surface of the connecting pipe, a heat exchange tube horizontally penetrating the inner cavity of the housing, a horizontally movable descaling component on the surface of the heat exchange tube, and a driving component for driving the descaling component to move horizontally at the lower part of the inner cavity of the housing.

[0007] Preferably, the installation mechanism includes two connecting rings, which are fixedly connected to the outer surface of the connecting pipe by fastening bolts. A connecting rod is fixedly connected to one end of each connecting ring, and a connecting plate is fixedly connected to one end of each connecting rod. One side of the connecting plate extends to the left side of the mounting flange.

[0008] Preferably, a threaded cylinder extends through the connecting plate, and a threaded rod is threadedly connected to the inner cavity of the threaded cylinder. One end of the threaded rod is rotatably connected to a fixed plate, and a telescopic rod is fixedly connected between the fixed plate and the side opposite to the connecting plate.

[0009] Preferably, the descaling assembly includes a retaining ring, which is sleeved on the surface of the heat exchange tube, and an annular scraper is fixedly connected to the inner side of the retaining ring via a connecting block.

[0010] Preferably, the driving assembly includes a lead screw, with its two ends rotating on both sides of the inner wall of the housing. A motor for driving the lead screw to rotate is provided on one side of the housing. A threaded block is threadedly connected to the surface of the lead screw. The bottom of the threaded block is slidably connected to the bottom of the inner wall of the housing. A push block is fixedly connected to the top of the threaded block. The top of the push block is fixedly connected to the surface of the fixing ring.

[0011] Preferably, a cooling water inlet pipe is connected to one side of the top of the housing, and a valve is provided on the cooling water inlet pipe. A cooling water outlet pipe is connected to the bottom of one side of the housing.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. Through the synergistic action of the drive component and the descaling component, when the motor drives the screw to rotate forward and backward, the threaded block drives the push block to move horizontally, which in turn pushes the fixed ring and the annular scraper to slide back and forth along the surface of the heat exchange tube. The annular scraper can scrape off the scale layer on the inner wall of the heat exchange tube in real time, avoiding the accumulation of dirt that leads to a decrease in heat exchange efficiency and ensuring long-term stable temperature control. At the same time, there is no need to stop the machine for manual cleaning, reducing maintenance costs and downtime losses. Meanwhile, when the threaded block, push block and descaling component move, the cooling water inside the shell can be shaken, improving the uniformity of contact between the cooling water and the heat exchange tube, and further improving the utilization rate of cooling water.

[0014] 2. Through the dual fixing design of the installation mechanism, rotating the threaded rod can push the fixing plate to fit against the outer wall of the compressor outlet pipe, realizing dual positioning of flange bolt fixing and pipe outer wall clamping, which improves the stability after installation and reduces the risk of material leakage.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4 The heat exchange device for regulating the temperature of the material at the outlet of a compressor shown includes a housing 1, a connecting pipe 2 on the left side of the housing 1, a mounting flange 7 at one end of the connecting pipe 2, a mounting mechanism 3 fixedly connected to the outer surface of the connecting pipe 2, a heat exchange pipe 4 horizontally passing through the inner cavity of the housing 1, a horizontally movable descaling component 5 on the surface of the heat exchange pipe 4, and a driving component 6 for driving the descaling component 5 to move horizontally at the lower part of the inner cavity of the housing 1.

[0024] The heat exchange tube 4 is connected to the connecting tube 2. A temperature sensor can be installed on the inner side of the connecting tube 2. The temperature sensor adopts existing technology and transmits the detection data to the PLC control system terminal. The operator can adjust the valve 9 on the cooling water inlet pipe 8 through the real-time temperature displayed on the terminal to control the cooling water feed rate and achieve precise control of the material temperature.

[0025] The mounting mechanism 3 includes two connecting rings 31, which are fixedly connected to the outer surface of the connecting pipe 2 by fastening bolts. A connecting rod 32 is fixedly connected to one end of each connecting ring 31, and a connecting plate 33 is fixedly connected to one end of each connecting rod 32. One side of the connecting plate 33 extends to the left side of the mounting flange 7.

[0026] A threaded cylinder 34 passes through the connecting plate 33. A threaded rod 35 is threadedly connected to the inner cavity of the threaded cylinder 34. A fixed plate 36 is rotatably connected to one end of the threaded rod 35. A telescopic rod 37 is fixedly connected between the fixed plate 36 and the side opposite to the connecting plate 33.

[0027] The telescopic rod 37 is used to support the fixed plate 36, prevent the fixed plate 36 from rotating with the threaded rod 35, and ensure that the fixed plate 36 always remains horizontal and fits against the outer wall of the compressor outlet pipe.

[0028] The descaling assembly 5 includes a fixing ring 51, which is sleeved on the surface of the heat exchange tube 4. An annular scraper 52 is fixedly connected to the inner side of the fixing ring 51 through a connecting block.

[0029] The annular scraper 52 is attached to the surface of the heat exchange tube 4. The annular scraper 52 is made of polytetrafluoroethylene, which has both wear resistance and flexibility, and can remove dirt without scratching the heat exchange tube 4.

[0030] The drive assembly 6 includes a lead screw 61, with both ends of the lead screw 61 rotating on both sides of the inner wall of the housing 1. A motor 62 is provided on one side of the housing 1 to drive the lead screw 61 to rotate. A threaded block 63 is threadedly connected to the surface of the lead screw 61. The bottom of the threaded block 63 is slidably connected to the bottom of the inner wall of the housing 1. A push block 64 is fixedly connected to the top of the threaded block 63. The top of the push block 64 is fixedly connected to the surface of the fixing ring 51.

[0031] The surface of the lead screw 61 is galvanized or chrome-plated for rust and corrosion prevention to avoid rusting from prolonged contact with cooling water.

[0032] Motor 62 is a three-phase asynchronous AC motor. Motor 62 drives lead screw 61 to rotate in both directions, and drives descaling component 5 to move back and forth through threaded block 63 and push block 64.

[0033] A cooling water inlet pipe 8 is connected to one side of the top of the housing 1. A valve 9 is provided on the cooling water inlet pipe 8. A cooling water outlet pipe 10 is connected to the bottom of one side of the housing 1. The cooling water inlet pipe 8 and the cooling water outlet pipe 10 are connected to the external cooling circulation system.

[0034] The working principle of this practical application is as follows:

[0035] Align the mounting flange 7 of the connecting pipe 2 with the compressor outlet pipe flange, tighten the bolts, and then rotate the threaded rod 35 on the connecting plate 33. The threaded rod 35 is pushed into the threaded cylinder 34, pushing the fixing plate 36 to fit against the outer wall of the compressor outlet pipe. The fixing plate 36 is kept stable by the telescopic rod 37, achieving dual fixation of the flange and clamp. When disassembling, rotate the threaded rod 35 in the opposite direction, loosen the fixing plate 36, and then remove the flange bolts, simplifying the disassembly and assembly process.

[0036] High-temperature gas or liquid from the compressor outlet enters the heat exchange tube 4 through the connecting pipe 2. The external cooling circulation system injects cooling water into the shell 1 through the cooling water inlet pipe 8. The cooling water flows in the shell side and exchanges heat with the high-temperature material in the heat exchange tube 4. The cooled material is output from the other end of the heat exchange tube 4 to the subsequent process. The temperature sensor detects the material temperature in real time. The operator adjusts the cooling water flow through the valve 9 to ensure that the material temperature meets the standard. The motor 62 starts and drives the lead screw 61 to rotate. The threaded block 63 drives the push block 64 to move horizontally, which in turn pushes the fixed ring 51 and the annular scraper 52 to slide back and forth along the surface of the heat exchange tube 4 to scrape off the scale. The scale is discharged from the cooling water outlet pipe 10 with the cooling water, ensuring stable heat exchange efficiency. When the threaded block 63, the push block 64 and the descaling component 5 move, the cooling water inside the shell 1 can be shaken, which improves the uniformity of contact between the cooling water and the heat exchange tube 4 and further improves the utilization rate of the cooling water.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
