Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically relating to a gas-liquid separation device with backwashing and a spray tower. Background Technology

[0002] During the waste gas treatment process, the exhaust gas from the spray tower usually carries a certain amount of water vapor. If it is not removed sufficiently, it will reduce the service life of subsequent equipment (such as activated carbon). Therefore, a gas-liquid separation device needs to be installed at the exhaust outlet of the spray tower to further remove water vapor.

[0003] The gas-liquid separation devices in related technologies are demisters with built-in wire mesh or baffle plates or hollow spheres. After a period of use, water vapor adheres to the demister or hollow sphere, which increases the pressure loss of the equipment and affects the treatment effect of the exhaust gas. It is necessary to disassemble the device regularly and flush the inside, and repeat the process.

[0004] Therefore, how to clean the demister without affecting the airtightness of the separation device is a technical problem that urgently needs to be solved.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0046] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Please see Figure 1This disclosure provides a gas-liquid separation device with backflushing, comprising: a housing 100 having an air inlet 110 and an exhaust outlet 120; a demister 200 disposed within the housing 100 and located between the air inlet 110 and the exhaust outlet 120 to remove water vapor from the exhaust gas introduced through the air inlet 110; and a flushing assembly 300 disposed within the housing 100 for flushing the demister 200. By providing the flushing assembly 300 between the demister 200 and the exhaust outlet 120, the housing 100 does not need to be disassembled when cleaning the demister 200, thus maintaining the original sealing performance of the housing 100.

[0050] The flushing assembly 300 is disposed between the demister 200 and the exhaust port 120, and the flushing direction of the flushing assembly 300 is opposite to the exhaust direction of the demister 200. The flushing direction of the flushing assembly 300 (e.g., Figure 1 (as shown in F2) and the exhaust direction of the gas-liquid separator (as shown in F2) Figure 1 (As shown in F1) The reverse setting forms a backwash to prevent liquid from entering the exhaust port 120 during flushing.

[0051] Please continue reading. Figure 1 The rinsing assembly 300 includes: a rinsing rod 310 for rinsing the demister 200; a water inlet pipe 320 that passes through the top of the housing 100 and communicates with the rinsing rod 310; and a drain pipe 330 that passes through the bottom of the housing 100.

[0052] Water is supplied to the flushing rod 310 through the water inlet pipe 320. After the water enters the flushing rod 310, it is sprayed towards the demister 200 to complete the flushing of the demister 200. The flushed water is discharged from the housing 100 through the drain pipe 330, thus completing the entire flushing process without disassembling the housing 100, thereby not damaging the sealing of the housing 100.

[0053] Please continue reading. Figure 1 The rinsing rod 310 includes: a rod body 311 disposed within the housing 100; and a plurality of spiral nozzles 312 spaced apart along the axial direction of the rod body 311 and communicating with the rod body 311. The spiral nozzles 312, through their internal spiral structure, decompose the fluid into tiny vortices, thereby achieving a more uniform spraying effect and reducing water consumption.

[0054] In some embodiments, the rod body 311 is horizontally disposed within the housing 100; or, the rod body 311 is vertically disposed within the housing 100. The orientation of the rod body 311 is not limited to horizontal or vertical, as long as it meets the rinsing requirements of the demister 200. Furthermore, the shape of the rod body 311 can be, but is not limited to, elongated, annular, etc., as long as it serves to support the spiral nozzle 312.

[0055] Please see Figure 2 The number of flushing rods 310 is multiple; the multiple flushing rods 310 are spaced apart in the housing 100 along the length direction of the demister 200; the tops of the multiple flushing rods 310 are connected to the water inlet pipe 320 through a connecting pipe 313.

[0056] Please see Figure 1 and Figure 2 The rinsing assembly 300 further includes a driving member 340; the driving member 340 is used to drive the rinsing rod 310 to reciprocate in the horizontal direction or in the vertical direction to complete the cleaning of the demister 200; and the plane on which the rinsing rod 310 moves is arranged parallel to the cleaning surface of the demister 200.

[0057] The position of the flushing rod 310 is adjusted by the drive component 340, thereby improving the flushing effect on the demister 200.

[0058] To prevent the water inlet pipe 320 from becoming loose when the flushing rod 310 moves, the water inlet pipe 320 includes a connector 321 and a connecting hose 322; the connector 321 is located at the top of the housing 100; one end of the hose passes through the housing 100 and is connected to the connector 321, and the other end is connected to the connecting pipe 313 inside the housing 100.

[0059] The connector 321 is connected to the connecting pipe 313 by a connecting hose 322. When the flushing rod 310 moves, the sealing between the connecting hose 322 and the housing 100 will not be affected.

[0060] Please continue reading. Figure 1 The bottom of the housing 100 is sloped, and the slope angle α is between 2 and 6°, so as to drain the liquid inside the housing 100 from the drain pipe 330. By setting the bottom of the housing 100 to be sloped, it is easier to drain the flushing water inside the housing 100.

[0061] This disclosure also provides a spray tower, including: a spray tower body and a gas-liquid separator with backwashing as described above; the gas-liquid separator with backwashing is connected to the exhaust port of the spray tower body. By collecting water vapor in the exhaust gas of the spray tower through the gas-liquid separator with backwashing, when the demister 200 needs cleaning, it is not necessary to disassemble the housing 100; the flushing assembly 300 can be directly controlled to operate, improving flushing efficiency and avoiding damage to the sealing of the housing 100 during disassembly.

[0062] The beneficial effects of this utility model are that it provides a gas-liquid separation device and a spray tower with backwashing. The gas-liquid separation device with backwashing includes: a housing 100, which is provided with an air inlet 110 and an exhaust outlet 120; a demister 200, which is disposed in the housing 100 and located between the air inlet 110 and the exhaust outlet 120, to remove water vapor from the exhaust gas introduced from the air inlet 110; and a flushing assembly 300, which is disposed in the housing 100 and is used to flush the demister 200. The flushing assembly 300 is disposed between the demister 200 and the exhaust outlet 120, and the flushing direction of the flushing assembly 300 is opposite to the exhaust direction of the demister 200. By installing a flushing assembly 300 between the demister 200 and the exhaust port 120, the housing 100 does not need to be disassembled when the demister 200 needs to be cleaned. At the same time, the flushing direction of the flushing assembly 300 is set opposite to the exhaust direction of the gas-liquid separator to form backflushing, so as to prevent liquid from entering the exhaust port 120 during flushing.

[0063] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0064] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
