TECHNICAL FIELD

[0001] The present application relates to the technical field of incinerators, in particular to a VOC waste gas incinerator. BACKGROUND

[0002] VOC waste gas, i.e. volatile organic compound waste gas, is a kind of waste gas composed of organic compounds that can evaporate into a gaseous state at room temperature, which needs to be treated to meet the emission standard.

[0003] At present, when VOC waste gas is treated, an incinerator is often used for incineration to burn harmful impurities in the VOC waste gas, so that the VOC waste gas meets the emission standard.

[0004] However, the VOC waste gas often carries impurities such as particulate matter and grease before entering the incinerator, which may cause blockage and corrosion problems after contacting the pipeline and the furnace wall of the incinerator, directly affecting the working efficiency and service life of the incinerator.

During processing, VOC waste gas is introduced into the incineration cavity through the air inlet pipe 11, then the VOC waste gas is incinerated through the incineration part, and then the incinerated VOC waste gas is discharged through the air outlet pipe 12.

[0048] Referring to Figure 2 , in order to reduce impurities in the VOC waste gas entering the air inlet pipe 11, a filter box 2 is fixedly arranged on the side, away from the furnace body 1, of the air inlet pipe 11. A filter cavity 21 is formed in the filter box 2, the air inlet pipe 11 is connected to the filter box 2 at a position close to the top, and the air inlet pipe 11 is connected with the filter cavity 21.

The filter box 2 is provided with a support plate 3, the support plate 3 is located in the filter cavity 21, and the side wall of the support plate 3 is in contact with the side wall of the filter cavity 21. A water storage groove 25 is formed between the support plate 3 and the bottom wall of the filter cavity 21, and water flow is stored in the water storage groove 25. The filter box 2 is provided with a filter layer 26, the filter layer 26 is placed on the top of the support plate 3, the filter layer 26 is made of sponge material, and the filter layer 26 fills the space between the support plate 3 and the top wall of the filter cavity 21. The support plate 3 is obliquely provided with air permeable holes 31, the air permeable holes 31 are multiple and uniformly arranged.

[0050] In use, the VOC waste gas is input into the water storage groove 25 through the input pipe 22, at this time, the VOC waste gas is in contact with the water flow, and the water flow absorbs impurities in the VOC waste gas; then the VOC waste gas is in contact with the filter layer 26 after passing through the air permeable holes 31, then the filter layer 26 absorbs water vapor in the VOC waste gas, and the amount of water entering the air inlet pipe 11 is reduced.

[0051] Referring to Figure 2 and Figure 3 , in order to improve the effect of the water flow absorbing impurities in the VOC waste gas, the input pipe 22 extends into the filter cavity 21, and the bottom of the input pipe 22 is rotatably connected with a connecting pipe 23, the connecting pipe 23 is multiple and uniformly arranged along the extension direction of the input pipe 22, and the side end of the connecting pipe 23, away from the input pipe 22, is closed.

[0059] The VOC waste gas is first passed into the filter cavity 21 and contacted with the water flow to absorb impurities in the VOC waste gas, and then passed into the furnace body 1 after absorbing water vapor in the VOC waste gas through the filter layer 26 for incineration. After the VOC waste gas is incinerated, the VOC waste gas is discharged from the gas outlet pipe 12 and contacted with the heating part 51, at this time, the water flow flowing through the heating part 51 absorbs heat and is taken back into the water storage tank 25, so that the VOC waste gas is heated, which is beneficial to recycling and reusing the heat in the VOC waste gas.
