[0002] Waste gas treatment is also called waste gas purification. Waste gas treatment refers to the pre-treatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the national standards for waste gas external discharge. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment and air sterilization and purification, and waste gas treatment equipment is needed in the phenolic and epoxy fiberglass composite molding process.

[0003] The existing waste gas treatment equipment for phenolic and epoxy fiberglass composite molding purifies the generated waste gas through physical purification, i.e. activated carbon adsorption, during the purification process. In the above method, due to the adsorption saturation of the activated carbon, it is necessary to replace it regularly. During the replacement process, the transportation of the waste gas needs to be stopped, and the production equipment needs to be shut down, which not only affects its production efficiency, but also affects the use effect of the equipment, resulting in the inability of the equipment to continuously and efficiently treat the waste gas. Therefore, there is an urgent need for a waste gas treatment equipment for phenolic and epoxy fiberglass composite molding to solve the above problems. Utility Model Content

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In order to solve the problem that the existing waste gas treatment equipment for phenolic and epoxy fiberglass composite molding purifies the generated waste gas by physical purification, that is, by activated carbon adsorption during use, in the purification process of the above method, due to the adsorption saturation of activated carbon, it is necessary to replace it regularly, and during the replacement process, the transportation of the waste gas needs to be stopped, and the production device needs to be shut down, which not only affects its production efficiency, but also affects the use effect of the device, resulting in the problem that the device cannot continuously and efficiently treat the waste gas. The utility model adopts a double-station mechanism, that is, two groups of purification sleeves, and designs a reversing mechanism composed of a motor, a main gear, a sub-gear, a screw and a reversing plate.
