DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5The specific implementation modes of the present utility model are further described in detail.

[0024] Embodiment 1

[0025] An environmentally friendly waste gas treatment device includes a dust removal box 10, and a dust removal bag 20 is installed at the upper end of the dust removal box 10. The dust removal bag 20 is a common structure in the prior art and is not described in detail here. The specific improvements of this embodiment are:

[0026] An air intake pipe 30 is provided at the lower end of the dust removal box 10, and a dispersion component 40 is provided at the upper end of the air intake pipe 30. The dispersion component 40 includes receiving plates 41 fixed on both sides of the upper end of the air intake pipe 30. The two receiving plates 41 form a V-shaped funnel structure at the upper end of the air intake pipe 30, and the mouth of the air intake pipe 30 is located between the two receiving plates 41 and a plurality of dispersion plates 42 are fixedly provided thereon. A plurality of channels 401 for the flow of exhaust gas are formed between adjacent dispersion plates 42 and between the dispersion plates 42 and the receiving plates 41. When in use, the exhaust gas enters through the air intake pipe 30 and enters the dust removal box 10 under the guiding and diverting action of the dispersion component 40. In this way, the exhaust gas can be in contact with the surface of the dust bag 20 as evenly as possible.

[0027] A connecting groove 31 is provided at the upper end of the air intake pipe 30 , and the exhaust gas enters the connecting groove 31 through the air intake pipe 30 , and then enters different channels 401 through the connecting groove 31 .

[0028] In order to remove large particles in the exhaust gas and prevent large particles from being blocked on the surface of the dust bag 20, so that the dust bag 20 can work for a longer time, the lower end of the dust removal box 10 is connected to the cyclone dust removal chamber 50, and the lower end inlet of the air inlet pipe 30 is arranged at the upper end of the cyclone dust removal chamber 50. An air inlet pipe 51 is provided on the upper end side of the cyclone dust removal chamber 50. The air inlet direction of the air inlet pipe 51 is tangent to the wall surface of the cyclone dust removal chamber 50. In this way, when the exhaust gas enters the cyclone dust removal chamber 50, it will rotate around the inner wall of the cyclone dust removal chamber 50. Under the action of centrifugal force, the large particles in the exhaust gas are gradually thrown to the inner wall of the cyclone dust removal chamber 50, and then gradually move downward under the action of gravity and are discharged through the lower end of the cyclone dust removal chamber 50, while the small particles in the exhaust gas enter the dust removal box 10 through the air inlet pipe 30.

[0029] A bag dust removal device is provided at the upper end of the dust removal box 10 .

[0030] In this embodiment, the bag dust removal device is a pulse air blowing device 60, which is a prior art. By blowing high-pressure air into the mouth of the dust bag 20, the dust on its surface is shaken off, and the shaken off dust just falls between the funnel structure formed by the two receiving plates 41, enters the cyclone dust removal chamber 50 through the air inlet pipe 30, and is discharged from the dust outlet at the lower end of the cyclone dust removal chamber 50. After entering the funnel structure, the dust will enter the connecting groove 31. In order to facilitate the dust to enter the air inlet pipe 30, the bottom of the connecting groove 31 can also be designed to be funnel-shaped.

[0031] The number of the dispersion plates 42 is at least three.

[0032] In order to prevent the moist exhaust gas from entering the dust removal box 10 and causing the dust to harden on the surface of the dust removal bag 20 , a dehumidification device 70 is provided in the cyclone dust removal chamber 50 .

[0033] The dehumidification device 70 is an electric heating plate structure embedded and fixed on the inner wall of the cyclone dust removal chamber 50. The exhaust gas inside the cyclone dust removal chamber 50 is heated by the electric heating plate, thereby drying the exhaust gas.

[0034] Embodiment 2

[0035] The second embodiment provides an environmentally friendly waste gas treatment device, which is substantially the same in structure as the first embodiment, except that the dust removal bag 20 is connected to a mounting frame 21 , and the bag dust removal device is a vibration mechanism 80 disposed on the mounting frame 21 .

[0036] In this embodiment, the vibration mechanism 80 is a vibration motor 81a, and the mounting frame 21 is fixed with a rubber block 22, which is fixedly connected to the inner wall of the dust removal box 10. When in use, the vibration motor 81a works to vibrate the dust bag 20, thereby shaking off the dust on the surface of the dust bag 20.

[0037] Embodiment 3

[0038] The mounting frame 21 is vertically slidably disposed at the upper end of the dust removal box 10 , and the vibration mechanism 80 is a power component 81 b that drives the mounting frame 21 to move up and down in the dust removal box 10 , and the power component 81 b may be a cylinder.

[0039] An environmentally friendly exhaust gas treatment device, the working principle of which is as follows: the exhaust gas enters the cyclone dust removal chamber 50 through the air inlet pipe 51, and the large particles in the exhaust gas gradually approach the inner wall of the cyclone dust removal chamber 50 through the centrifugal effect and are discharged from the ash outlet below, and the smaller particles enter the dispersion component 40 through the air inlet pipe 30 after drying. Under the diversion effect of the dispersion plate 42, the exhaust gas is more evenly dispersed in the dust removal box 10 and contacts the surface of the dust removal bag 20, thereby solving the problem of the exhaust gas of the bag dust collector entering from the side and having uneven contact with the bag in the prior art.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
