Description

Technical Field

[0001] The present application relates to the field of waste incineration treatment, and in particular to a waste incineration flue gas treatment device. Background Art

[0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, turning it into residue or molten solid matter.

[0003] At present, when treating the flue gas from garbage incineration, most of the time, a filtering structure is set on the exhaust pipe, such as an activated carbon layer for adsorption, or it is passed into a treatment liquid for catalytic reduction. However, the gas volume is large. When the flue gas is passed into the treatment liquid in a stream, the flue gas flows into a mass, resulting in the flue gas in the middle of the air mass not easily coming into contact with the treatment liquid, affecting the flue gas treatment effect.

[0004] Therefore, the present application provides a waste incineration flue gas treatment device to solve the above technical problems. Utility Model Content

The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a waste incineration flue gas treatment device, including a treatment box, the bottom of which is filled with treatment liquid, a box cover fixed to the top of the treatment box, a vertical air inlet pipe fixed to the box cover, the lower end of the air inlet pipe extending below the liquid level of the treatment liquid, and a horizontal air distribution pipe rotatably installed, the lower end surface of the air distribution pipe is fixed with a plurality of docking pipes, and an exhaust pipe is installed on one side of the top of the treatment box;

[0007] A drive box is fixed on the top of the air inlet pipe, a motor is installed in the drive box, a fan and a drive rod are fixed to the shaft of the motor in sequence, and the lower end of the drive rod extends into the air distribution pipe and is fixed to the air distribution pipe.

[0008] Furthermore, a planetary reducer is installed at the lower end of the driving rod, and the planetary reducer is fixed to the middle bottom surface of the air distribution pipe.

[0009] Furthermore, a horizontal fixing plate is fixed in the driving box, and the motor is fixed to the middle part of the upper end surface of the fixing plate.

[0010] Furthermore, a vertical butt joint pipe is fixed to the middle of the upper end surface of the air distribution pipe, and the butt joint pipe is rotatably installed in the lower port of the drive box.

[0011] Furthermore, a cleaning brush is installed on the upper end surface of the air distribution pipe, and the top of the cleaning brush extends above the liquid level of the treatment liquid.

[0012] Furthermore, a horizontal adsorption net is fixed in the middle of the processing box, and the adsorption net is located on the liquid surface of the processing liquid.

[0013] Furthermore, a through opening is provided in the middle of the adsorption net for the air inlet pipe to pass vertically through.

[0014] Furthermore, the cleaning brush abuts against the lower end surface of the adsorption net.

[0015] The beneficial effect of the present application is that it provides a waste incineration flue gas treatment device, which introduces the waste incineration flue gas into the treatment liquid through the air inlet pipe, and cooperates with the rotatable air distribution pipe installed at the lower end of the air inlet pipe to use the air nozzle to disperse the flue gas into multiple small streams, thereby ensuring the contact effect with the treatment liquid and improving the treatment effect of the waste incineration flue gas.

[0016] At the same time, in conjunction with the setting of the adsorption net, the flue gas treated with the treatment liquid can be further filtered, and in conjunction with the setting of the connecting tube on the gas distribution pipe, the gas distribution pipe can also use the connecting tube to clean the filter holes of the adsorption net when rotating to ensure the filtering effect of the adsorption net, thereby further improving the treatment effect of the waste incineration flue gas.

[0017] In summary, this device can disperse the garbage incineration flue gas into multiple flue gases, and carry out treatment liquid treatment and adsorption net filtering, which ensures the treatment effect and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

The treatment liquid 3 can be, but is not limited to, a sodium hydroxide solution and is used to remove acidic gases from the flue gas. A box cover 2 is fixed to the top of the treatment box 1. A vertical air inlet pipe 201 is fixed to the box cover 2. The lower end of the air inlet pipe 201 extends below the liquid level of the treatment liquid 3, allowing the waste incineration flue gas to pass into the treatment liquid 3 for treatment. In addition, an exhaust pipe 101 is installed on one side of the top of the treatment box 1 to discharge the treated flue gas.

[0033] At the same time, cooperate Figure 3 and Figure 4 As shown, a horizontal air distribution pipe 7 is rotatably mounted on the lower end of the air intake pipe 201, and a plurality of docking pipes 702 are fixed to the lower end surface of the air distribution pipe 7. Specifically, a vertical docking pipe 702 is fixed to the middle portion of the upper end surface of the air distribution pipe 7. The docking pipe 702 is rotatably mounted within the lower end of the drive box 202. The drive box 202 is fixed to the top of the air intake pipe 201, and a fixing plate 203 is fixed within the drive box 202. The fixing plate 203 is mounted on the motor 4.

The planetary reducer 601 is fixed to the bottom surface of the middle portion of the air distribution pipe 7.

[0034] Furthermore, a cleaning brush 703 is mounted on the upper end of the air distribution pipe 7, with the top of the brush 703 extending above the level of the treatment liquid 3.
