DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figure 1-Figure 8As shown, the condensing equipment for chemical plants provided in this embodiment includes a shell 1 and a plurality of circulation pipes 2. The circulation pipes 2 are U-shaped. A partition plate 3 is fixedly connected inside the shell 1. The interior of the shell 1 is divided into an upper and lower cavity by the partition plate 3. One end of the circulation pipe 2 located at the upper part of the shell 1 is an air inlet end 4, and the other end of the circulation pipe 2 is an air outlet end 5. The high-temperature gas discharged from the chemical plant circulates from the air inlet end 4 to the air outlet end 5, which is convenient for heat dissipation and cooling of the high-temperature gas, so that the water vapor inside the high-temperature gas condenses into water droplets. The air inlet end 4 and the air outlet end 5 are convenient for cleaning the inside of the circulation pipe 2. The plurality of circulation pipes 2 are fixedly connected to the partition plate 3. A sealing plate 6 is provided on one side of the shell 1. The two ends of the plurality of circulation pipes 2 are sealed by the sealing plate 6, which is convenient for the high-temperature gas to circulate inside the circulation pipe 2. The inside of the sealing plate 6 is fixedly connected There are multiple cylinders 7, and the inside of the cylinder 7 is slidably connected with a push rod 8. The push rod 8 is fixedly connected with a sealing plug 9 at one end close to the circulation pipe 2. The sealing plug 9 corresponds to the air inlet end 4 and the air outlet end 5 respectively. The sealing plug 9 can be moved to the inside of the circulation pipe 2, and the circulation pipe 2 is sealed by the sealing plug 9. By injecting high-pressure gas into the cylinder 7, the push rod 8 slides inside the cylinder 7, and the push rod 8 moves while pushing the sealing plug 9 to move. The side of the multiple circulation pipes 2 close to the air inlet end 4 is commonly connected with an air inlet pipe 10, and one end of the air inlet pipe 10 extends to one side of the shell 1. The high-temperature gas discharged from the chemical plant enters the inside of the circulation pipe 2 through the air inlet pipe 10. The side of the multiple circulation pipes 2 close to the air outlet end 5 is commonly connected with a water collecting pipe 11. After the high-temperature gas is cooled after passing through the circulation pipe 2, the condensed water droplets will flow into the water collecting pipe 11.

[0028] Further, such as Figure 1-Figure 8 As shown, a sealing block 12 is slidably connected to the inner side of the sealing plate 6 close to the partition plate 3, and one side of the sealing block 12 corresponds to the partition plate 3. The sealing block 12 and the partition plate 3 are in contact with each other, so that the upper and lower parts of the shell 1 are completely divided into two cavities.

[0029] Among them, Figure 1-Figure 8 As shown, a plurality of springs 13 are provided between the sealing block 12 and the sealing plate 6, and the plurality of springs 13 are used to pull the sealing block 12 to reset, so that the sealing block 12 can automatically reset without the push of air pressure. A spring 2 14 is provided between the push rod 8 and the cylinder 7, and the spring 2 14 is used to pull the push rod 8 to reset, so that after the high-pressure gas in the cylinder 7 is emptied, the spring 2 14 pulls the push rod 8 to move.

[0030] Further, such as Figure 1-Figure 8As shown, the interiors of the multiple cylinders 7 are interconnected, which is convenient for high-pressure gas to enter the multiple cylinders 7 and enable the multiple cylinders 7 to maintain synchronous operation. The upper surface of the sealing plate 6 is fixedly connected with a high-pressure intake pipe 15, one end of which is connected to the cylinder 7. The high-pressure gas enters the cylinder 7 through the high-pressure intake pipe 15, pushing the multiple push rods 8 to move. The lower surface of the sealing plate 6 is fixedly connected with an exhaust pipe 16, one end of which is connected to the cylinder 7. The high-pressure gas in the cylinder 7 can be discharged through the exhaust pipe 16, so that the push rod 8 is automatically reset under the action of the spring 14.

[0031] Among them, Figure 1-Figure 8 As shown, a bracket 17 is fixedly connected to the upper surface of the shell 1 near the sealing plate 6, and an electric telescopic rod 18 is fixedly connected to the upper surface of the bracket 17. The output end of the electric telescopic rod 18 is fixedly connected to the upper surface of the sealing plate 6. The electric telescopic rod 18 is used to drive the sealing plate 6 to move upward, so that one side of the shell 1 is opened to facilitate cleaning of the circulation pipe 2. An air pump 19 is fixedly connected to the upper surface of the bracket 17, and the air pump 19 is connected to the high-pressure air intake pipe 15. The high-pressure gas is transported to the inside of the high-pressure air intake pipe 15 through the air pump 19.

[0032] Among them, Figure 1-Figure 8 As shown, the interior of the water collecting pipe 11 is connected to an exhaust pipe 20. After the water vapor in the gas discharged from the factory condenses into water droplets, the remaining gas will be discharged through the exhaust pipe 20. One end of the exhaust pipe 20 extends to the outside of the shell 1. One end of the exhaust pipe 20 is connected to an exhaust gas treatment device 21. The toxic gas contained in the exhaust gas discharged from the exhaust pipe 20 is purified after passing through the exhaust gas treatment device 21. The lower end of the water collecting pipe 11 is connected to a sewage treatment device 22. The sewage treatment device 22 is used to filter the toxic substances in the water droplets, so as to facilitate the pollution-free treatment of the water droplets.

[0033] Among them, Figure 1-Figure 8 As shown, the other side of the shell 1 is connected with a refrigeration pipe 23 and a refrigeration pipe 24 respectively. One end of the refrigeration pipe 23 and the refrigeration pipe 24 respectively extend into the inside of the shell 1. The refrigeration pipe 23 and the refrigeration pipe 24 are commonly connected with a refrigeration component 25. After the refrigeration component 25 is working, low-temperature air is generated. The low-temperature air is circulated in the shell 1 through the refrigeration pipe 23 and the refrigeration pipe 24, so as to achieve the effect of lowering the outer wall of the circulation pipe 2.

[0034] like Figure 1-Figure 8As shown, the principle of the condensing equipment for chemical plants provided in this embodiment is as follows: after the refrigeration component 25 works, low-temperature air is produced and enters the shell 1 for circulation, and the outer wall of the circulation pipe 2 is cooled accordingly. The exhaust gas generated by the factory enters the circulation pipe 2 through the air inlet pipe 10. After being cooled inside the circulation pipe 2, the water vapor will condense into water droplets and flow into the water collecting pipe 11. The remaining gas will then pass through the exhaust pipe 20 to enter the exhaust gas treatment device 21. The water droplets flowing into the water collecting pipe 11 will flow into the sewage treatment device 22 for treatment. When it is necessary to clean the circulation pipe 2, by turning off the air pump 19, the high-pressure gas in the cylinder 7 is discharged through the exhaust pipe 16. Under the action of multiple springs 13 and multiple springs 2 14, the push rod 8 drives the sealing plug 9 to move, so that the sealing plug 9 is disconnected from the circulation pipe 2, and the sealing block 12 is disconnected from the mutual interference with the sealing plate 6. Finally, the sealing plate 6 is moved upward under the drive of the electric telescopic rod 18 to facilitate the cleaning of the circulation pipe 2.
