[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 3 , a wet dust removal device for industrial waste gas treatment, comprising a dust removal water tank 1, a lower end of one side of the dust removal water tank 1 is connected to an air inlet pipe 101, an upper end of the dust removal water tank 1 is connected to an exhaust pipe 102, and also comprises: a guide plate 3, which is equidistantly staggered and fixedly connected in the dust removal water tank 1; a first filter plate 301, which is fixedly connected between every two adjacent guide plates 3; a diverter box 202, which is fixedly connected to the inner wall of the dust removal water tank 1 near the first filter plate 301, and a side of the diverter box 202 near the first filter plate 301 is equidistantly connected to a plurality of water spray heads; a water pump 201, which is symmetrically arranged at the lower ends of both sides of the dust removal water tank 1, and the water inlets of the two water pumps 201 are respectively connected to the diverter box 202 on the same side through water pipes; a purification mechanism for purifying sewage flowing out of the dust removal water tank 1, which is installed at the water outlet at the bottom of the dust removal water tank 1.

[0022] The purification mechanism includes a purified water tank 2, the water inlet of the purified water tank 2 is connected to the water outlet of the dust removal water tank 1, a second filter plate 203 is connected to the purified water tank 2, a water pump 201 is arranged in the purified water tank 2 below the second filter plate 203, and the water inlet of the water pump 201 is connected to the purified water tank 2.

[0023] When treating industrial waste gas, it is necessary to first clean the dust particles and other impurities in the waste gas, and then treat the harmful substances in the industrial waste gas. By separating the dust particles and other impurities from the harmful substances in the industrial waste gas, it can be ensured that the industrial waste gas is treated more fully. When it is necessary to clean the dust particles and other impurities in the waste gas, firstly, clean water is transported to the dust removal water tank 1 through the air intake pipe 101 until the clean water covers the uppermost guide plate 3, and then the air intake pipe 101 can be connected to the air delivery pipe of the industrial waste gas, and the exhaust pipe 101 can be connected to the exhaust pipe 101. 02 is connected with the device of the next processing process. After the previous work is ready, the industrial waste gas can be transported to the dust removal water tank 1 through the air inlet pipe 101. When the industrial waste gas enters the clean water, the dust particles and other impurities in the industrial waste gas will be mixed into the water, so that they can be separated from the industrial waste gas. Since the gas will float upward in the water, the industrial waste gas will float upward in an S shape along the multiple guide plates 3, thereby extending the time that the industrial waste gas stays in the water, so as to facilitate the full filtration of impurities in the industrial waste gas and harmful substances dissolved in water.

[0024] By arranging the first filter plate 301 between each guide plate 3, impurities in the flowing gas can be filtered out again, and the removal effect of impurities such as dust particles in the industrial waste gas can be further improved. When the industrial waste gas is transported to the dust removal water tank 1, the water pump 201 can be started at the same time. The water pump 201 will transport the water filtered by the second filter plate 203 to the diversion box 202 through the water pipe and spray it to the first filter plate 301 through the nozzle, wherein the water sprayed from the nozzle is opposite to the direction of gas flow. Therefore, when the industrial waste gas passes through the first filter plate 301 and flows upward, the water sprayed by the nozzle can further prevent the flow rate of the industrial waste gas, thereby further prolonging the time that the industrial waste gas stays in the water, so as to more fully filter out the impurities in the industrial waste gas and the harmful substances soluble in water. At the same time, the water in the dust removal water tank 1 can also be purified to increase the use time of the water.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 3, a wet dust removal device for industrial waste gas treatment is basically the same as Example 1, and furthermore: an inclined plate 104 is installed at the lower end of the interior of the dust removal water tank 1. Through the setting of the inclined plate 104, when a large amount of impurities such as dust particles separated from the exhaust gas accumulate at the bottom of the dust removal water tank 1 and need to be cleaned, the discharge pipe of the purified water tank 2 can be opened at this time to discharge the dust removal water tank 1 cleanly, leaving only a part of the water in the purified water tank 2, and then the pump 201 can be started, and then the water pumped by the pump 201 will be sprayed to the first filter plate 301 through the nozzle to clean the first filter plate 301 and the guide plate 3. When the water flows downward to the inclined plate 104, the dust particles and other impurities attached to the inclined plate 104 can be flushed, so that the dust particles and other impurities accumulated at the bottom of the dust removal water tank 1 can be cleaned out without manual cleaning, which effectively improves the removal effect of dust particles and other impurities.

[0027] The second filter plate 203 is tiltedly arranged in the purified water tank 2. Figure 3 As shown in the inclined setting, when the sewage in the dust removal water tank 1 is connected with impurities such as dust particles and enters the purification water tank 2 for separation through the second filter plate 203, the filtered sewage can quickly flow downward through the filter holes on the second filter plate 203, thereby ensuring the water pumping volume of the purified sewage by the water pump 201.

[0028] A slot is provided in the purified water tank 2, and the second filter plate 203 is horizontally inserted in the slot. When the water in the dust removal water tank 1 needs to be replaced after being used for a long time, the second filter plate 203 can be removed from the purified water tank 2, so that the dust particles and other impurities intercepted on the second filter plate 203 can be cleaned, which provides convenience for the staff to clean the second filter plate 203.

[0029] Embodiment 3:

[0030] Reference Figure 1-Figure 3 , a wet dust removal device for industrial waste gas treatment, which is basically the same as Example 2, and further: the filter holes on the multiple first filter plates 301 decrease from bottom to top. By making the filter holes on the multiple first filter plates 301 decrease from bottom to top, each first filter plate 301 can only intercept impurities such as dust particles of the same specification, thereby reducing the interception pressure of the bottom first filter plate 301, which can not only improve the adequacy of removing impurities such as dust particles in the waste gas, but also avoid the bottom first filter plate 301 from being blocked and affecting the throughput of the waste gas.

[0031] A transparent plate 103 is integrally formed on the dust removal water tank 1. The transparent plate 103 allows the staff to check the internal conditions of the dust removal water tank 1, thereby providing convenience for the staff.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
