[0024] An integrated waste gas purification device for waste gas treatment includes: a base plate 1, on which a bracket 2, a waste gas treatment box 10 and an absorption tower 24 are arranged, a pretreatment tank 3 is fixedly connected to the bracket 2, one side of the pretreatment tank 3 is provided with an air intake pipe 4, a first transfer pipe 8 is arranged on the upper part of the pretreatment tank 3, a draft fan 9 is arranged on the first transfer pipe 8, the other end of the first transfer pipe 8 extends to the lower part of the waste gas treatment box 10, a stirring device is arranged inside the waste gas treatment box 10, a foaming component and a second drain pipe 22 are arranged at the bottom of the waste gas treatment box 10, a purified liquid inlet pipe 20 and a second transfer pipe 23 are arranged on the upper part of the waste gas treatment box 10, a closing plug 21 is arranged on the purified liquid inlet pipe 20, and the other end of the second transfer pipe 23 extends to the bottom of the absorption tower 24.

[0025] The waste gas is passed through the air inlet pipe 4 into the pretreatment tank 3 for preliminary treatment. The waste gas after one treatment enters the bottom of the waste gas treatment box 10 through the first transfer pipe 8. At this time, the waste gas treatment box 10 has added a sufficient amount of waste gas purification liquid (such as water and various acids and alkaline solutions used for waste gas treatment, etc.) into the interior through the purification liquid inlet pipe 20, and then a stirring device and a foaming component are used to promote the accelerated reaction between the purification liquid and the waste gas, and finally the waste gas is passed into the absorption tower 24 for treatment of the residual waste gas.

[0026] The upper part of the pretreatment tank 3 is provided with a water supply port 5 , the bottom of the water supply port 5 is provided with an atomizing nozzle 3 , and the bottom of the pretreatment tank 3 is provided with a first drain pipe 7 .

[0027] The waste gas enters the pretreatment tank 3, where it is first sprayed with water to remove a small amount of solid waste contained in the waste gas, and the washed waste water is discharged from the first drain pipe 7 below.

[0028] The stirring device includes a motor 11, which is fixedly connected to the outer wall of the exhaust gas treatment box 10. A rotating shaft 12 is provided at the output end of the motor 11.

A groove 132 is provided at one end of the blade 131 away from the rotating shaft 12. A through opening 133 is provided on the blade 131.

[0029] The stirring fan 13 stirs the purified liquid in the exhaust gas treatment box 10 to accelerate the reaction rate between the pollutants and the purified liquid. The groove 132 prevents the fan 13 from hitting other devices and components in the exhaust gas treatment box 10 during rotation.

[0031] The blower 14 blows air into the foaming machine 16 through the input pipe 15, and then inputs the air into the purified liquid in the waste gas treatment box 10, thereby increasing the reaction area between the pollutants and the purified liquid and accelerating the treatment speed.

[0032] A heater 18 is disposed on the upper portion of the exhaust gas treatment box 10 , and a heating portion 19 is disposed on the lower portion of the heater 18 . The lower portion of the heating portion 19 extends to a lower portion inside the exhaust gas treatment box 10 .

The second transfer pipe 23 is located at the lower part of the first purification layer 25 . The top of the absorption tower 24 is provided with a discharge port 28 .

[0035] The first purification layer 25, the second purification layer 26 and the third purification layer 27 can be filled with suitable materials according to the type of waste gas to be treated, such as using activated carbon and various composite purification materials as adsorption materials to prevent the treated waste gas from still containing a small amount of pollutants, resulting in incomplete purification effect.

[0036] The working principle of the integrated exhaust gas purification device for exhaust gas treatment provided by the utility model is as follows:

[0037] The waste gas is passed through the air inlet pipe 4 into the pretreatment tank 3 for preliminary treatment. The waste gas after one treatment enters the bottom of the waste gas treatment box 10 through the first transfer pipe 8. At this time, the waste gas treatment box 10 has added a sufficient amount of waste gas purification liquid (such as water and various acids and alkaline solutions used for waste gas treatment, etc.) into the interior through the purification liquid inlet pipe 20, and then a stirring device and a foaming component are used to promote the accelerated reaction between the purification liquid and the waste gas, and finally the waste gas is passed into the absorption tower 24 for treatment of the residual waste gas.

[0038] Compared with the related art, the integrated waste gas purification device for waste gas treatment provided by the utility model has the following beneficial effects:

[0039] After three treatments in the pretreatment tank 3, the waste gas treatment box 10 and the absorption tower 24, pretreatment, waste gas purification and residual pollutant treatment are respectively performed, so that the waste gas treatment is more thorough, avoiding the problem that the existing device does not purify the waste gas thoroughly, resulting in a small amount of pollutants remaining when the purified gas is discharged, resulting in a reduced purification effect.
