It is installed on the inner wall or bottom of the washing tank 5, which is convenient for absorbing large-area iron filings and can effectively absorb iron particles suspended in water. At the same time, it can reduce the need for maintenance and cleaning. Overflow seams are arranged around the washing tank 5. The water level of the washing liquid is controlled and fresh washing liquid is added through the overflow seams. The washing tank 5 is connected with a funnel 7 through the overflow seam. The funnel 7 is made of metal material and plays a role in regulating the water flow. A filtering mechanism 8 is connected below the funnel 7. Impurities in the washing liquid can be filtered through the filtering mechanism 8. A water pump 9 is connected to one side of the filtering mechanism 8.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details:

[0028] As a preferred embodiment, a fan 3 is connected to one side of the air duct opening 2, and the side of the fan 3 away from the air duct opening 2 is connected to the inside of the workshop. The harmful air and impurities in the workshop are introduced into the device through the fan 3, so as to be efficiently processed.

[0029] As a preferred embodiment, the shell 1 is cylindrical so that there are no dead corners inside to avoid gas retention, and an air outlet 18 is provided at the top of the shell 1. The air outlet 18 discharges the purified air out of the interior of the shell 1 to reduce harm to the environment. A demisting layer 19 is provided below the air outlet 18. The demisting layer 19 is a blade-type demisting layer composed of multiple groups of parallel blades. It can remove droplets carried up from the packing layer and the spray layer, reduce liquid entrainment losses, and prevent corrosion of downstream pipelines and equipment.

[0030] As a preferred embodiment, the filtering mechanism 8 includes a one-way valve 13, a filter screen 14 and a filter element 15. One-way valves 13 are provided at both ends of the filtering mechanism 8. The one-way valves 13 prevent backflow from occurring and contamination of the washing liquid. A filter screen 14 is provided on one side of the filtering mechanism 8, and a filter element 15 is provided on one side of the filter screen 14. By using the combination of the filter screen 14 and the filter element 15, impurities floating in the washing liquid can be filtered out.

[0031] As a preferred embodiment, the spray mechanism 10 is annular in shape to increase the gas-liquid contact surface. Two groups of spray mechanisms 10 are provided, and the two groups of spray mechanisms 10 are evenly arranged along the inner wall of the housing 1 in the vertical direction.

[0032] As a preferred embodiment, the spray mechanism 10 includes a spray pipe 16 and a nozzle 17. The spray pipe 16 is a pipe body made of metal material. The metal material has the advantage of strong corrosion resistance. One side of the spray pipe 16 is connected to the water pump 9, and the other side of the spray pipe 16 is connected to the nozzle 17. The nozzle 17 is an atomizing nozzle that produces fine droplets, which can effectively remove particulate impurities in the oil fume. At the same time, due to the small droplets, the transfer efficiency is also increased.

[0033] As a preferred embodiment, several groups of nozzles 17 are provided, and each group of nozzles 17 is evenly arranged in the horizontal direction of the spray pipe 16, so that there is no dead angle above the packing layer 11, preventing gas from escaping and improving cleaning efficiency.

[0034] The working process of the utility model is as follows: first, the fan 3 is connected to the air duct in the workshop, and the air carrying impurities and the oil smoke generated by the work enter the air duct port 2. The air duct port 2 allows the air and impurities to enter the gas distributor 4, and enter the interior of the device through the holes of the gas distributor 4, reducing the pressure drop and dead zone. After the gas enters, it naturally rises and floats over the packing layer 11. The spray mechanism 10 is used above the packing layer 11 to continuously spray the washing liquid to the packing layer 11. The washing liquid forms a liquid surface on the surface of the packing layer 11 and the filter plate 12. The gas passing through the liquid surface will make the impurities therein The impurities are carried away by the liquid surface, and then enter the washing tank 5 below under the action of gravity. A magnet 6 is provided in the washing tank 5 to preliminarily clean out the metal particles in the impurities. The impurities sink to the bottom of the washing tank 5 under the action of gravity, and the washing liquid enters the filtering mechanism 8 below through the overflow seam to filter the fine impurities therein again, and then is sprayed down from the spray mechanism 10 under the action of the water pump 9 for recycling. The treated gas passes through the demisting layer 19 to remove the moisture in the gas and is discharged into the atmosphere through the outlet 18. The above is the working principle of the dust and oil fume treatment device in the spinning workshop.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
