[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] like Figure 1-4 As shown, the utility model proposes a waste gas treatment mechanism for glass fiber reinforced plastic grating processing, comprising a waste gas processor 1, a through air guide pipe 22 is installed at the lower part of the waste gas processor 1, the other end of the air guide pipe 22 is connected to an exhaust terminal seat 23, an air inlet terminal seat 21 is built with an air induction device, and the air induction end face of the air inlet terminal seat 21 faces the glass fiber reinforced plastic grating processing table, and the waste gas generated in the production process of the glass fiber reinforced plastic grating is collected into the inner cavity of the waste gas processor 1, and an exhaust terminal seat 23 for exhaust is also provided on the top of the waste gas processor 1;

[0025] The spray mechanism includes a convex plate 31 disposed at the lower part of the exhaust gas processor 1, and a plurality of spray devices 33 are disposed at the opening of the convex plate 31, and the spray devices 33 are connected to an external liquid supply device through a liquid inlet pipe 32;

[0026] The filter mechanism includes a support plate 41 spaced apart in the inner cavity of the waste gas processor 1, and a through ventilation groove 42 is provided on the support plate 41. A filter material 44 is arranged above the support plate 41, and a sealing plate 43 is installed at the end of the filter material 44 to seal against the side wall of the waste gas processor 1.

[0027] It should be noted that the convex plate 31 separates the waste gas processor 1 into upper and lower cavities, the lower cavity is a spray treatment cavity, and the upper cavity is an adsorption treatment cavity. After the waste gas passes through the waste gas processor 1, it is subjected to spray treatment and adsorption treatment, and then the gas that meets the green production requirements can be discharged.

[0028] In this embodiment, the waste gas first enters the spray treatment chamber of the waste gas processor 1. Since the convex plate 31 has only an opening at the upper part, and a plurality of spray devices 33 are arranged at the opening, the spray device 33 sprays the liquid medicine input from the liquid inlet pipe 32 downward in an atomized manner. When the waste gas floats upward, it mixes with the medicine mist, and the waste gas is treated once. The falling droplets are attached with a large amount of impurities mixed with the waste gas.

[0029] The floating waste gas enters the adsorption treatment chamber after the primary treatment. The filter material 44 of the adsorption treatment chamber is stacked and clamped between two adjacent support plates 41. The filter material 44 and the ventilation groove 42 form a serpentine channel for gas transmission, which increases the transmission path of the waste gas in the channel. During the transmission process, impurities are adsorbed in the inner cavity of the filter material 44.

[0030] The waste gas after secondary filtration treatment can be discharged normally.

[0031] It should be added that: a total of four groups of support plates 41 are provided, and the ventilation slots 42 provided on two adjacent support plates 41 are located opposite to each other, so that the filter material 44 can be fully utilized when the exhaust gas passes through the two ventilation slots 42 .

[0032] In order to facilitate the collection of waste liquid in the waste gas treatment process, a waste liquid tank 34 is further provided at the bottom of the waste gas processor 1, and drain gutters are spaced apart on the waste liquid tank 34. Water droplets generated by the medicine mist mixed with impurities fall into the waste liquid tank 34 under the action of gravity. Because of its built-in drain pipe 35 that runs through the outer wall of the waste gas processor 1, the waste liquid can be discharged from the waste gas processor 1.

[0033] like Figure 3 As shown, the positioning mechanism includes a positioning track 51 arranged at the interlayer of the support plate 41 , and the slot specifications of the positioning track 51 are adapted to the specifications of the limiting slide seat 52 formed on the side wall of the filter material 44 .

[0034] It should be noted that the filter material 44 is a detachable structure. When it is blocked and needs to be replaced, the sealing plate 43 is pulled, and the limiting slide 52 can pull the filter material 44 out of the inner cavity of the waste processor 1 when positioning the track 51. Since the filter material 44 at the bottom is in contact with the most exhaust gas and has a higher degree of blockage, it can be replaced first.

[0035] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
