Description

Technical Field

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

[0002] Coal chemical industry refers to the process of using coal as raw material and converting it into gas, liquid and solid chemicals and fuels through chemical processing. The main processes include coal gasification, liquefaction, distillation, tar processing and calcium carbide acetylene chemical industry. In the coal chemical processing process, the chemical structure of organic matter in coal is a macromolecular structure with aromatic condensed rings as the unit core, connected by bridge bonds and carrying various functional groups. Through thermal processing and catalytic processing, coal can be converted into various fuels and chemical products.

[0003] The temperature of coal will rise after gasification. Directly liquefying the high-temperature coal will cause the coal to drop suddenly from high temperature to low temperature, which will cause the equipment to deform more seriously, thus affecting the service life of the equipment and the efficiency of the conversion process. Therefore, further improvements are needed on this basis. Utility Model Content

[0027] A cooling structure, which is installed inside the processing box 1 and is used to cool the gas inside the gas pipeline 2;

[0028] Compared with the prior art, by arranging a pressure regulating component in the middle part of the gas pipeline 2, the gas transportation efficiency in the gas pipeline 2 can be effectively improved, and by arranging a cooling structure at the position of the pressurizing chamber 9 of the gas pipeline 2, the pressurized gas can be cooled to avoid deformation of the gas pipeline 2 due to excessive temperature.

[0034] When it is necessary to cool the gasified coal, the gasified coal gas enters the gas pipeline 2 through the air inlet 21 of the gas pipeline 2, and the gas pipeline 2 is a one-way pipeline. In order to increase the rate of gas transportation along the gas pipeline 2, the adjusting shaft 4 inside the processing box 1 is controlled to rotate, and the adjusting shaft 4 then drives the adjusting rod 1 6 and the adjusting rod 2 7 to rotate. Since the two ends of the connecting shaft 10 are respectively hinged to the adjusting rod 1 6 and one end of the first piston 11, the first piston 11 can slide horizontally along the inside of the pressurizing chamber 9 through the rotation of the adjusting rod 1 6.

[0038] While transporting the gas, the coolant is transported from one end of the water inlet 31 of the cooling pipe 3 into the cooling pipe 3 and finally discharged from the water outlet 32 ​​, so that the gas transported in the gas pipeline 2 can be cooled.

[0039] See also Figure 3 In addition to the above technical solution, the present invention also provides another embodiment. The difference between this embodiment and the above embodiment is that the first piston 11 and the second piston 12 are both made of aluminum alloy, which can effectively improve the corrosion resistance of the first piston 11 and the second piston 12, thereby increasing the service life of the first piston 11 and the second piston 12.

In order to increase the speed of gas transportation along the gas pipeline 2, the adjustment shaft 4 inside the processing box 1 is controlled to rotate, and the adjustment shaft 4 then drives the adjustment rod 1 6 and the adjustment rod 2 7 to rotate. Since the two ends of the connecting shaft 10 are respectively hinged to the adjustment rod 1 6 and one end of the first piston 11, the first piston 11 can slide horizontally along the inside of the pressurizing chamber 9 through the rotation of the adjustment rod 1 6, and the first piston 11 can slide horizontally along the inside of the pressurizing chamber 9. Since the two ends of the swing rod 8 are respectively hinged to the adjusting rod 27 and the connecting rod 5, the connecting rod 5 can slide back and forth in the horizontal direction through the rotation of the adjusting rod 27, thereby driving the second piston 12 to slide back and forth horizontally inside the pressurizing chamber 9, thereby realizing pressure regulation of the pressurizing chamber 9, reducing the time for the gas to reach the exhaust port 22 from the air inlet 21 of the exhaust pipe, and while transporting the gas, the coolant is transported from one end of the water inlet 31 of the cooling pipe 3 to the cooling pipe 3, and finally discharged from the water outlet 32, so that the gas transported in the gas pipeline 2 can be cooled.
