Background Art

At present, in the process of workpiece grinding production or paint room production, a lot of dust gas and paint gas will be generated, which need to be filtered before discharge. In the prior art, when filtering the dust gas or paint gas, multi-stage filtration is generally required. The first stage of filtration is generally water filtration, which filters most of the dust particles in the gas by spraying water to contact the gas; however, when using the existing water filtration device, we found that it only relies on spraying to make water and gas contact, resulting in some gases unable to completely contact and filter with water, making the first stage of water filtration and purification effect poor, which greatly affects the overall filtration effect of the gas; for this reason, we propose a water curtain filter device.

As a preferred embodiment; the first water curtain filter mechanism 2 also includes a first water tank 9 and a first drain pipe 10, the first water tank 9 and the first drain pipe 10 are respectively fixedly connected to the inner top of the device body 1, the first drain pipe 10 is arranged on the top surface of the first water tank 9, the first water curtain 5 is fixedly mounted on the side of the first water tank 9 and the top of the first water curtain 5 is lower than the top surface of the first water tank 9; the inner top of the device body 1 is also fixedly mounted with a water baffle 11, and there is a gap between the water baffle 11 and the first water curtain 5; it can be understood that: the bottom surface of the first drain pipe 10 is provided with a plurality of water outlets, water is continuously discharged into the interior of the first water tank 9, and when it is full, it can overflow and flow to the first water curtain 5 (due to the presence of a gap, water can continuously flow to the first water curtain 5 and then flow down), and at the same time, by providing a water baffle 11, water splashing can be avoided, and it is convenient for water to continuously flow through the first water curtain 5.

As a preferred embodiment; the second water curtain filtering mechanism 3 also includes a second water tank 12 and a second drain pipe 13, the second water tank 12 is fixedly mounted on the side of the first water tank 9, the second drain pipe 13 is arranged on the top surface of the second water tank 12, the second water curtain 7 is fixedly mounted on the bottom of the second water tank 12 and a guide plate 14 is also installed between the second water curtain 7 and the second water tank 12; it can be understood that: the bottom surface of the second drain pipe 13 is also provided with a plurality of water outlet holes, and water is continuously discharged into the interior of the second water tank 12. When it is full, it can overflow to the guide plate 14, and then flow down to the second water curtain 7.

As a preferred embodiment; a fixed water curtain 15 is also fixedly installed on the inner side wall of the device body 1, and a gas channel 16 is formed between the fixed water curtain 15 and the second water curtain 7, and the gas channel 16 is an S-shaped structure; the fixed water curtain 15 is trumpet-shaped and can form an S-shaped structure with the second water curtain 7. When the gas circulates, the gas travel time can be extended to facilitate the gas to fully contact with water. At the same time, the channel between the first water curtain 5 and the second water curtain 7 is in a sealed state (the first water tank 9 and the second water tank 12 are blocked), so that the gas can only flow in the gas channel 16 (at the same time, an exhaust fan is provided at the end of the gas channel 16), which also allows the gas to pass through the first water curtain filter mechanism 2, the second water curtain filter mechanism 3 and the spray mechanism 4 in sequence, further improving the gas filtering effect.

The exhaust shell 21 can be connected to another external filtering device through an air pipe, so as to discharge the filtered gas into another filtering device. The exhaust fan provided at the same time not only increases the exhaust efficiency, but also can form a negative pressure in the filtering device, and the extracted gas flows in the filtering direction, thereby ensuring the filtering effect.

The working principle of the utility model is as follows: first, the exhaust fan is started to form a negative pressure inside the device body 1, and then the gas enters through the air inlet 6. The first water curtain filtering mechanism 2 uses the "membrane" effect and viscosity of water to attract the scattered excess dust with the air flow to the first water curtain 5 for purification, so that the gas is fully in contact with water. Then, the gas will enter the interior of the device body 1, and after entering, it will directly contact the filtered water sprayed by the sprinkler head 8 and the filtered water flowing down the second water curtain 7, and will be filtered again. The water filtering effect is better, and the dust particles in the gas are thoroughly filtered; finally, the gas after water filtration is discharged through the exhaust shell 21.

It should be pointed out that the main problem in the prior art is that the water and gas are simply contacted by spraying, which results in that part of the gas cannot be completely contacted with the water for filtration, resulting in poor first-stage water filtration and purification effect, which in turn greatly affects the overall filtration effect of the gas;

Therefore, through the improvement of the present application, the filtered gas can be completely in contact with water, and the dust particles in the gas can be completely filtered, thereby greatly improving the filtering effect of the gas.
