Description
Technical Field
[0001] The utility model relates to the technical field of washing towers, in particular to a high-efficiency and low-resistance gas washing tower. Background Art
[0002] The existing foam scrubber uses a perforated plate to allow the gas to be scrubbed to flow upward from the bottom and the liquid to flow downward from the top to form a foam layer, thereby purifying impurities in the gas with a large adsorption surface area. This is a highly efficient gas purification and adsorption device. However, the working gas velocity of this foam scrubber is required to be stable and must be within a specific range, which is highly restrictive, and the small holes on the plate are also easily clogged and need to be cleaned frequently. Moreover, it is not reliable enough when used in production to purify dirty gases and systems with wide system load fluctuations. Therefore, those skilled in the art provide a high-efficiency, low-resistance gas scrubber to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] As a further solution of the utility model: a cleaning port is opened on the outer surface of the tower body, and three cleaning ports are provided, and the three cleaning ports are respectively located at the upper part, the middle part and the lower part of the tower body.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] By setting the second cyclone plate, liquid and gas are convected, and a floating foam layer is generated in a vortex state to evolve the gas, and the floating foam layer is used to purify the gas. The amount of floating foam is linearly related to the gas flow rate. The larger the gas flow rate, the more foam is generated, so that the washing effect has better stability under the change of gas velocity, which is beneficial to reducing energy consumption, so that the application range of the washing tower is wide and the washing effect is efficient. In addition, since there are more gaps between the cyclones of the second cyclone plate, blockage is not easy to occur, ensuring that the ventilation resistance in the tower body is small. A first cyclone plate is also provided, and the direction of the first cyclone plate is opposite to that of the second cyclone plate, which can form a resistance opposite to the second cyclone plate to the gas. The first cyclone plate can block the water vapor contained in the discharged gas, ensuring that the gas discharged from the tower body has a low amount of foam. BRIEF DESCRIPTION OF THE DRAWINGS

An upper nozzle 5 is connected, and the other end of the upper nozzle 5 is fixedly connected to the outer surface of the tower body 1, and an upper spray pipe 14 is fixedly connected to the side where the upper nozzle 5 and the tower body 1 are connected, and the upper spray pipe 14 extends to the interior of the tower body 1. A three-way valve is fixedly connected to the surface of the annular tube 7, and the other two ports of the three-way valve are respectively fixedly connected to the main liquid inlet pipe 6 and the connecting pipe 9. An air intake pipe 10 is fixedly connected to the surface of the tower body 1, and one end of the air intake pipe 10 extends to the interior of the tower body 1 and is located on the lower side of the second swirl plate 13.
[0021] Preferably, the lower end of the connecting pipe 9 is fixedly connected to a lower nozzle 11, the lower end of the lower nozzle 11 is fixedly connected to a lower spray pipe 15, and the lower spray pipe 15 extends to the interior of the air inlet pipe 10 to wet the gas, increase the water content of the gas, initially enhance the weight of the gas, and slow down the flow rate of the gas.
[0022] Preferably, the upper spray pipe 14 is located between the first swirl plate 12 and the second swirl plate 13 .
[0023] Preferably, the swirl direction in the first swirl plate 12 is opposite to the swirl direction in the second swirl plate 13, and the swirl direction of the first swirl plate 12 is opposite to the swirl direction of the second swirl plate 13, which can form a resistance to the gas opposite to that of the second swirl plate 13. The first swirl plate 12 can block the water vapor contained in the discharged gas, ensuring that the gas discharged from the tower body 1 has a low foam content.
[0024] Preferably, one end of the air inlet pipe 10 located inside the tower body 1 opens upward.
[0025] Preferably, a cleaning port 4 is provided on the outer surface of the tower body 1 , and three cleaning ports 4 are provided, and the three cleaning ports 4 are respectively located at the upper part, the middle part and the lower part of the tower body 1 , so that the inside of the tower can be cleaned regularly through the cleaning ports 4 .
[0026] The working principle of the utility model is as follows: liquid is introduced from the main liquid inlet pipe 6, and the gas to be purified is introduced from the air inlet pipe 10. After the liquid is introduced from the main liquid inlet pipe 6, it first passes through the three-way valve, and then passes through the upper nozzle 5 and the lower nozzle 11, and is sprayed from the upper spray pipe 14 and the lower spray pipe 15 respectively. The liquid sprayed from the upper spray pipe 14 will directly enter the interior of the tower body 1, and the liquid sprayed from the lower spray pipe 15 will first contact with the gas in the air inlet pipe 10, soak the gas, increase the water content of the gas, preliminarily enhance the weight of the gas, and slow down the flow rate of the gas. Since the second swirl plate 13 is located between the air inlet pipe 10 and the upper spray pipe 14, the liquid sprayed from the upper spray pipe 14 acts on the upper side of the second swirl plate 13, and the gas passes through the gap between the swirl plates of the second swirl plate 13, and will contact with more water, thereby purifying the gas.

The larger the gas flow rate, the more foam is generated, so that the washing effect has better stability under the change of gas velocity, and because there are more gaps between the cyclones of the second cyclone plate 13, it is not easy to be blocked, so that the ventilation resistance in the tower body 1 is small, and the first cyclone plate 12 is also arranged on the upper side of the upper spray pipe 14, and the direction of the first cyclone plate 12 is opposite to that of the second cyclone plate 13, which can form a resistance opposite to the second cyclone plate 13 to the gas, and the water vapor contained in the discharged gas can be blocked by the first cyclone plate 12, so as to ensure that the gas discharged from the tower body 1 has a low foam content.
