Description

Technical Field

[0001] The utility model particularly relates to a device for purifying and treating xylene waste gas. Background Art

[0002] With the development of modern industry, the pollution of organic waste gas generated in the production process to the atmosphere is becoming increasingly serious. Currently, the equipment for purifying waste gas includes an organism. An inner cavity is arranged in the organism. An activated carbon adsorption plate is arranged on the inner cavity. A liquid infusion pipe is communicated with the organism. One end of the liquid infusion pipe extends into the inner cavity and is connected with a liquid spraying pipe. A ring-shaped escape pipe is arranged at the bottom of the inner cavity. The liquid infusion pipe conveys the washing liquid to the liquid spraying pipe, and the liquid spraying pipe sprays the washing liquid downward. The waste gas escapes upward through the ring-shaped escape pipe and enters the inner cavity. The washing liquid contacts the waste gas to wash and purify the organic waste gas, and the activated carbon adsorption plate adsorbs and traps the organic matters in the waste gas to remove harmful substances such as formaldehyde, benzene, and xylene in the waste gas. However, the following problems exist in use: In order to prevent the liquid spraying pipe from spraying the washing liquid on the side wall of the inner cavity, the liquid spraying pipe is generally arranged in the middle of the upper end of the organism, that is to say, the spraying amount of the washing liquid in the area close to the side wall of the inner cavity is extremely small, and the waste gas escaped from the ring-shaped escape pipe is relatively concentrated in the area close to the side wall of the inner cavity. When the waste gas escapes upward, it is difficult for the waste gas to effectively contact the washing liquid, resulting in an unsatisfactory washing and purifying effect. Summary of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides a device for purifying and treating xylene waste gas.

[0004] In order to solve the above-mentioned existing technical problems, the utility model adopts the following technical solutions:

[0005] A device for purifying and treating xylene waste gas includes a housing. An inner cavity is arranged on the housing. A ring-shaped escape pipe is arranged at the bottom of the inner cavity. A liquid infusion pipe is communicated with the upper end of the housing. One end of the liquid infusion pipe extends into the inner cavity and is provided with a liquid spraying pipe. A flow guiding component is arranged between the liquid spraying pipe and the ring-shaped escape pipe. The flow guiding component is used for distributing the flow direction of the waste gas escaped from the ring-shaped escape pipe.

[0006] Preferably, an activated carbon adsorption plate is arranged between the liquid spraying pipe and the ring-shaped escape pipe.

[0007] Preferably, the flow guiding component includes a fixing column arranged on the activated carbon adsorption plate. A connecting plate is arranged on the fixing column.

[0008] Preferably, the flow dividing plate and the connecting plate are hinged.

[0009] Preferably, the liquid spraying pipe is of a linear structure.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In this application, the re - distribution of the exhaust gas flow direction makes the exhaust gas passing through the flow dividing plate and the connecting plate relatively uniform. Then, when the liquid spraying pipe sprays the washing liquid downward, the diversion of the exhaust gas by the diversion assembly will increase the contact area between the washing liquid and the exhaust gas, thereby improving the washing and purification of the exhaust gas.

[0020] An equipment for purifying and treating xylene waste gas, referring to Figure 1 - Figure 2 , includes a housing 1, an inner cavity 2 is arranged on the housing 1, a ring-shaped escape pipe 3 is arranged at the bottom of the inner cavity 2, an infusion pipe 4 is communicated with the upper end of the housing 1, a liquid spraying pipe 5 is arranged at one end of the infusion pipe 4 extending into the inner cavity 2, and a diversion assembly is arranged between the liquid spraying pipe 5 and the ring-shaped escape pipe 3, and the diversion assembly is used for distributing the flow direction of the waste gas escaping from the ring-shaped escape pipe 3.

[0021] Further, an activated carbon adsorption plate 6 is arranged between the liquid spraying pipe 5 and the ring-shaped escape pipe 3.

[0022] Further, the diversion assembly includes a fixing column 71 arranged on the activated carbon adsorption plate 6, a connecting plate 72 is arranged on the fixing column 71, flow splitting plates 73 are respectively arranged at both ends of the connecting plate 72, a first through hole 721 is arranged on the connecting plate 72, a second through hole 731 is arranged on the flow splitting plate 73, and the aperture of the first through hole 721 is larger than that of the second through hole 731.

[0023] Further, the flow splitting plate 73 and the connecting plate 72 are hinged.

[0024] Further, the liquid spraying pipe 5 is of a linear structure.

[0025] The working principle of the present utility model is:

[0026] As an example of Embodiment 1, the washing liquid flows through the infusion tube 4 and enters the liquid spraying tube 5. The liquid spraying tube 5 sprays the washing liquid downward. To enhance the effective contact between the sprayed liquid and the waste gas, in this application, fixing columns 71 are provided on the activated carbon adsorption plate 6, a connecting plate 72 is connected to the upper ends of the fixing columns 71, and flow splitting plates 73 are arranged on both sides of the connecting plate 72. When the waste gas in the annular escape tube 3 escapes, it will move upward. The waste gas will first come into contact with the activated carbon adsorption plate 6. The activated carbon adsorption plate 6 will adsorb and capture harmful substances such as formaldehyde, benzene, and xylene in the waste gas. The waste gas after adsorbing the harmful substances will continue to move upward. Since the waste gas escaping from the annular escape tube 3 is mainly distributed in the area close to the inner wall of the inner cavity 2, when the waste gas after removing the harmful substances accumulates below the diversion assembly, the amount of waste gas accumulated below the flow splitting plate 73 and below the connecting plate 72 is uneven. In this application, the aperture of the second through hole 731 on the flow splitting plate 73 is set to be smaller than the aperture of the first through hole 721 on the connecting plate 72. Therefore, the waste gas accumulated below the flow splitting plate 73 will be diverted to the connecting plate 72. With this design, through the re-distribution of the flow direction of the waste gas, the waste gas passing through the flow splitting plate 73 and the connecting plate 72 will be relatively uniform. Then, when the liquid spraying tube 5 sprays the washing liquid downward, after the diversion of the waste gas by the diversion assembly, the contact area between the washing liquid and the waste gas will be increased, thereby improving the washing and purification of the waste gas. In the technology of this application, a connecting plate 72 and a flow splitting plate 73 are provided above the activated carbon adsorption plate 6. When the waste gas accumulates below the flow splitting plate 73, it will slowly move below the connecting plate 72. The connecting plate 72 and the flow splitting plate 73 are equivalent to covering the activated carbon adsorption plate 6, enhancing the adsorption and capture effect of the activated carbon adsorption plate 6 on the harmful substances in the waste gas, reducing the content of formaldehyde, benzene, and xylene in the waste gas, and further improving the purification effect. In the above technology, to make the washing liquid contact the waste gas more fully, the liquid spraying tube 5 can be driven to rotate by a rotating motor. Then, the infusion tube 4 needs to be made of a flexible hose material.

[0027] In the above technical solution, to improve the applicable range of this application, the connecting plate 72 and the flow splitting plate 73 are arranged in a hinged connection manner, which is convenient for the user to adjust the inclination angle of the flow splitting plate 73 on the connecting plate 72 according to the use scenario. For example, when the length of the liquid spraying tube 5 changes, the spraying range of the washing liquid will change; the hinged setting of the flow splitting plate 73 and the connecting plate 72 is also to make the diversion assembly more match the spraying range of different types of liquid spraying tubes 5 after diverting the waste gas.

[0028] Although the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of this disclosure is only for explanation and not for limiting the present utility model, but the scope of protection is defined by the content of the claims.
