Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a glass fiber reinforced plastic desulfurization purification tower with a backwashing mechanism. Background Art

[0002] The glass fiber reinforced plastic desulfurization purification tower is an important device for treating harmful substances such as sulfur dioxide in industrial waste gas. It has many remarkable advantages. First of all, the glass fiber reinforced plastic material has excellent corrosion resistance and can operate stably for a long time in a harsh chemical environment, effectively resisting corrosive components such as acids and alkalis in the waste gas. Secondly, the structure of this purification tower is reasonably designed, and usually has multiple layers of packing or spraying devices inside, increasing the contact area and time between the waste gas and the desulfurization agent, and improving the desulfurization efficiency. For example, in some thermal power plants, chemical plants and metallurgical enterprises, the glass fiber reinforced plastic desulfurization purification tower can effectively reduce the sulfur dioxide content in the waste gas to the level meeting the environmental protection emission standards, reducing the pollution to the atmospheric environment.

[0003] When the existing desulfurization filtration is carried out on the filter screen, over time, impurities will accumulate near the holes of the filter screen, and it is necessary to replace and clean the ash regularly. However, such efficiency is relatively slow, so a backwashing mechanism is needed. (Backwashing is a flushing operation opposite to the normal flow direction. In many industrial and domestic applications, fluids (liquids or gases) flow in a specific direction in a system or device. However, over time, impurities, dirt, sediment, etc. will accumulate inside the device, affecting the normal flow and function. Backwashing is to change the flow direction of the fluid to make it flow reversely, so as to use the reverse impact force, pressure and carrying effect of the fluid to remove the accumulated impurities, dirt, etc. from the inside of the device, achieving the purpose of cleaning and maintaining the device)

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] The present application will be further described in detail below with reference to the drawings and embodiments.

[0030] Refer to Figures 1 to 5 As shown in the figure, the embodiment of the present application provides a FRP desulfurization and purification tower with a backwashing mechanism, including a FRP tank body 1. A backwashing assembly 2 is arranged inside the FRP tank body 1, and a cooling assembly 3 is arranged on the outer wall of the FRP tank body 1. The backwashing assembly 2 includes an auxiliary support 29. The auxiliary support 29 is fixedly connected to the inner wall of the FRP tank body 1. A central shaft 26 is rotatably connected between the FRP tank body 1 and the auxiliary support 29. A first exhaust fan 27 and a second exhaust fan 28 are fixedly connected to the outer wall of the central shaft 26. One end of the central shaft 26 is fixedly connected to a driven pulley 25. The backwashing assembly 2 further includes a base 21. A servo motor 22 is fixedly installed inside the base 21. A driving pulley 23 is fixedly connected to the output shaft of the servo motor 22. A transmission belt 24 is wound between the driving pulley 23 and the driven pulley 25. A docking pipe 210 is fixedly installed on the top of the FRP tank body 1.

[0031] During specific implementation: By starting the servo motor 22, the driving pulley 23 can be driven to rotate. The driving pulley 23 can then drive the driven pulley 25 to rotate through the transmission belt 24. The driven pulley 25 can then drive the central shaft 26 to rotate. By adjusting the rotation direction of the output shaft of the servo motor 22, the rotation direction of the central shaft 26 can be controlled, and thus the first exhaust fan 27 and the second exhaust fan 28 can rotate forward or backward, thereby realizing the backwashing effect of the gas to remove the impurities attached to the holes of the filter screen.

[0032] Referring to Figures 1 to 5 , in one aspect of this embodiment, the cooling assembly 3 includes an outer water tank housing 31 fixedly connected to the outer wall of the fiberglass tank body 1. A space formed between the outer wall of the fiberglass tank body 1 and the outer water tank housing 31 is filled with a coolant. An installation hole 38 is opened at the bottom of the fiberglass tank body 1. A support frame 32 is fixedly connected to the outer wall of the outer water tank housing 31. The cooling assembly 3 further includes a refrigeration box 33, and a serpentine tube 36 is fixedly installed inside the refrigeration box 33. A first conduit 35 is fixedly connected to the top of the outer water tank housing 31. The cooling assembly 3 further includes a water pump 34 fixedly installed on the top of the refrigeration box 33. One end of the first conduit 35 is fixedly docked with the interface of the water pump 34, and the other interface of the water pump 34 is fixedly docked with one end of the serpentine tube 36. One end of the serpentine tube 36 is fixedly connected to a second conduit 37, and one end of the second conduit 37 is fixedly connected to the bottom of the outer water tank housing 31.

[0033] During specific implementation: Since sulfides mostly appear in scenarios such as thermal power plants or industrial metallurgy, a large amount of heat and high temperature are generated during the production of these sulfide gases. When the heat is conducted from the fiberglass tank body 1 to the coolant, by starting the water pump 34, the coolant in the outer water tank housing 31 is pumped out through the first conduit 35, passed through the serpentine tube 36 and quickly cooled by the refrigeration box 33. The serpentine tube 36 can enable the coolant to pass through the refrigeration box 33 for a longer time to dissipate more heat. Then, the coolant is sent back into the outer water tank housing 31 through the second conduit 37 to complete the cycle of heat dissipation. The installation hole 38 is used to install other pipes for discharging gas.

[0034] In this solution, all electrical equipment is powered by an external power supply.

[0035] Working principle: By starting the servo motor 22, the driving pulley 23 can be driven to rotate. The driving pulley 23 can then drive the driven pulley 25 to rotate through the transmission belt 24. The driven pulley 25 can then drive the central shaft 26 to rotate. By adjusting the rotation direction of the output shaft of the servo motor 22, the rotation direction of the central shaft 26 can be controlled. Furthermore, the first exhaust fan 27 and the second exhaust fan 28 can be rotated forward or backward, thereby realizing the reverse flushing effect of the gas to remove the impurities attached to the holes of the filter screen. Since sulfides mostly appear in scenarios such as thermal power plants or industrial metallurgy, a large amount of heat is generated when these sulfide gases are produced and the temperature is high. When the heat is conducted to the coolant through the main body 1 of the fiberglass tank, the coolant in the outer water tank housing 31 is pumped out through the first conduit 35 by starting the water pump 34, and is rapidly cooled by the refrigeration box 33 through the serpentine tube 36. The serpentine tube 36 can enable the coolant to pass through the refrigeration box 33 for a longer time to dissipate more heat. Then, the coolant is sent back into the outer water tank housing 31 through the second conduit 37 to complete the circulating heat dissipation. The mounting holes 38 are used to mount other pipes for discharging gas.
