[0002] A stenter is a key equipment for post-finishing of textile printing and dyeing. Since the temperature of the fabric is relatively high during the heat setting process, a large amount of high-temperature gas containing various pollutants will be generated in the drying room of the stenter. Direct inhalation of this gas can directly damage the respiratory mucosa of the human body, have a certain stimulating effect on the human respiratory tract and lungs, reduce the body's immune function, cause symptoms such as coughing, chest tightness, and shortness of breath, airway constriction, and increased breathing resistance. Therefore, a waste gas treatment device for the stenter is needed to purify its tail gas.

[0003] The existing waste gas treatment device for the stenter consists of a high-voltage electrostatic mechanism, a spraying mechanism, and an oil-water separation mechanism. When in use, first, the spraying mechanism sprays condensed water onto the waste gas to liquefy the organic matter in the waste gas. The liquefied organic matter mixes with water and flows into the oil-water separation mechanism along with the condensed water. The remaining preliminarily purified waste gas enters the high-voltage electrostatic mechanism for oil and mist removal. However, the existing waste gas treatment device for the stenter is bulky, requires a large industrial land area in the factory area, and the pipeline system is complex in layout and high in cost due to the wide layout area. Moreover, due to the low integration degree, the manufacturing cost of the waste gas treatment device for the stenter has been remaining high. Therefore, there is an urgent need to design a waste gas treatment device for the stenter with high integration degree, low cost, and small floor area. Summary of the Utility Model

[0022] A cleaning water pump 27 and a washing water pump 28 are arranged on the side of the oil-water separation tank 16; the cleaning water pump 27 is communicated with the cleaning spray part 5 through a cleaning water pipe 401; the washing water pump 28 is communicated with the washing spray part 9 through a washing water pipe 402.

[0023] Both the cleaning spray part 5 and the washing spray part 9 are located on a spray bracket 6; the spray bracket 6 is fixedly connected with the inner wall of the waste gas treatment tower body 2.

[0024] Upper and lower support plates 21 and 23 are respectively arranged on the upper and lower sides of the oil mist removal pipe 20, the support plates are fixed at both ends of the oil mist removal pipe 20, and both side support plates are installed on the inner wall of the waste gas treatment tower body 2.

[0025] A confluence hopper 15 is arranged at the bottom of the liquid collection tank 14; the confluence hopper 15 is connected with the liquid inlet distributor 24.

[0026] The air distribution plate 10 is located on the frame mounting seat 12; the frame mounting seat 12 is fixedly connected to the inner wall of the waste gas treatment tower body 2.

The liquid dispersion net 31 is a fine stainless steel wire mesh, and the liquid distribution bottom plate 32 is an orifice plate with uniformly distributed holes. When installed, it can be tilted appropriately to facilitate the dripping of water droplets; when the water in the liquid collection tank 14 flows through the liquid distribution plate, the liquid dispersion net 31 can spread the water horizontally and then drip from the holes of the liquid distribution bottom plate 32 to achieve the purpose of uniform distribution.

[0028] The waste gas of the stenter enters from the air inlet 30 under the drive of an external device, passes through the waste gas treatment tower body 2, and is discharged from the air outlet hood 1. When the waste gas passes through the inside of the waste gas treatment tower body 2, it first passes through the washing assembly: after the waste gas is eliminated from the air flow dead angle by the air distribution plate 10 and then highly sprayed and washed by the upper washing spray part 9, the waste gas enters the demister 7, undergoes preliminary demisting treatment, and then the waste gas enters the oil mist removal device 4. It is highly purified when passing through the oil removal and demisting pipe 20, the lower cathode suspension 22, and the upper cathode suspension 18, and finally is discharged from the air collection hood 1; the washing assembly and the demister 7 are generally arranged in two stages, and can also be arranged in one stage or multiple stages.

The water is evenly distributed by the liquid distribution plate 31 arranged inside the liquid distribution device 24, and the water drips into the oil-water separation tank body 16 in the shape of water droplets. After the oil in the water is separated by the tank body 16, due to the low density of the oil, it will automatically float to the water surface to form an oil-water layer. Then, the oil floating on the surface is scraped away by the oil scraper 25 and enters the subsequent treatment process. The remaining water is transported back to the cleaning spray part 5 and the washing spray part 9 by the cleaning water pump 27 and the washing water pump 28 on the side of the oil-water separation tank 16, and so on.
