Description

Technical Field

[0001] The present invention relates to the technical field of shell-and-tube heat exchangers, and particularly to a shell-and-tube heat exchanger. Background Technique

[0002] The working principle of a shell-and-tube heat exchanger is based on the principle of heat conduction. One fluid flows inside the tube bundle, while another fluid flows outside the tubes. When the two fluids flow through the inside and outside of the tube bundle respectively, due to the temperature difference, heat will be transferred from the high-temperature fluid to the low-temperature fluid. In this process, the tube bundle wall serves as a medium for heat conduction, transferring heat from one side to the other side.

[0003] According to a corrosion-proof shell-and-tube heat exchanger disclosed in the publication number CN208779986U, which includes a heat exchanger body. The middle part of the heat exchanger body includes a shell, and both ends of the shell are connected with tube boxes. At the connection parts where the shell and the tube boxes are connected to the tube boxes and the shell respectively, there are fixedly connected sealing extension plates, and the shell is connected to the tube box through the sealing extension plates. A liquid inlet pipe 1 is fixedly communicated with the left side surface of one tube box.

[0004] For this corrosion-proof shell-and-tube heat exchanger, when it is in use, although this material improves the corrosion resistance of the heat exchanger, ensures the long-term use of the heat exchanger, improves the heat transfer efficiency of the heat exchanger, and achieves the advantage of corrosion resistance, there will be a certain amount of heat energy loss during the use of the heat exchanger, which will further lead to a reduction in the heat transfer efficiency.

When the flow rate of the fluid is too fast, in order to avoid the occurrence of water hammer phenomenon when closing the valve, at this time, water hammer control operation is required. Then, rotate the turntable 37 to drive the adjusting rod 36 to rotate correspondingly inside the sealing block 351, thereby causing the movable grid plate 38 to move in the up and down directions inside the control seat 35, so as to change the relative position with the fixed grid plate 39, and then control the water flow inside the water inlet pipe 32 to flow into the water outlet pipe 34, thus realizing the water hammer control operation and playing a role in protecting the entire pipeline. Embodiment 3

[0028] Refer to Figures 1 - 12 , and on the basis of Embodiment 1, it is further obtained that the control mechanism 4 includes a support seat 41, the support seat 41 is fixedly connected to the top of the water inlet pipe 32, a support frame 42 is arranged inside the support seat 41, a filter screen 43 is fixedly connected inside the support frame 42, a top pipe 44 is fixedly connected to the top of the support seat 41, a clamping seat 45 is fixedly connected to the left end of the support frame 42, an L-shaped seat 46 is fixedly connected to the left top end of the support seat 41, a fourth spring 461 is fixedly connected inside the L-shaped seat 46, one end of the fourth spring 461 is fixedly connected with a round block 48, a T-shaped shaft 47 is fixedly connected inside the round block 48, and a vertical plate 49 is fixedly connected to the bottom end of the round block 48.

[0030] During the actual operation process, when this device is used, when using the shell-and-tube heat exchanger, when it is necessary to strengthen the heat preservation effect around the tube body 1, the corresponding heat preservation cover 214 needs to be installed at this time. Then, hold the rear T-shaped lever 2251 and the front T-shaped lever 2254, and let the front T-shaped lever 2254 drive the rectangular rod 2253 to slide under the limiting support of the L-shaped plate 226 after overcoming the elastic force of the second spring 2252.

However, when the flow rate of the fluid is too fast, in order to avoid water hammer phenomenon when closing the valve, water hammer control operation is required at this time. Then, rotate the turntable 37 to drive the adjusting rod 36 to rotate correspondingly inside the sealing block 351, thereby causing the movable grid plate 38 to move in the up and down direction inside the control seat 35, so as to change the relative position with the fixed grid plate 39, and then control the water flow inside the water inlet pipe 32 to flow into the water outlet pipe 34, so as to realize the water hammer control operation and play a role in protecting the entire pipeline; In addition, when water enters, there may be impurities in the fluid, and corresponding filtration is required at this time. Then, the filter screen 43 can be used for filtration. When it is necessary to clean the filter screen 43, pull the T-shaped shaft 47 to move under the limit inside the L-shaped seat 46, and then drive the vertical plate 49 to slide under the limit inside the L-shaped seat 46, so that the vertical plate 49 moves to the middle notch above the clamping seat 45. After that, the clamping seat 45 can be pulled out and then the filter screen 43 can be removed, so as to facilitate the cleaning operation of the filter screen 43 and correspondingly ensure the flow of the entire device and avoid the occurrence of blockage phenomenon.
