[0002] The environmental protection purification box for waste gas treatment of coating equipment is a kind of equipment specially designed to treat waste gas generated in the coating process. With the development of industrial coating technology, the impact of waste gas generated in the coating process on the environment and human health has attracted increasing attention. Therefore, the development of an efficient and environmentally friendly coating waste gas treatment equipment has become an urgent need in the industrial field. Traditional coating waste gas treatment methods mainly include adsorption, combustion, condensation and biological treatment. However, these methods often have problems such as low treatment efficiency, high operating costs, and easy secondary pollution. In order to solve these problems, the environmental protection purification box for waste gas treatment of coating equipment came into being. The design of the environmental protection purification box also needs to consider factors such as waste gas treatment efficiency, treatment cost, floor space, and noise. By optimizing the equipment structure, improving equipment performance, and reducing operating costs, efficient and environmentally friendly treatment of coating waste gas can be achieved, promoting the sustainable development of the coating industry.

[0003] After reviewing relevant patent documents, it is found that there are still some problems with the environmentally friendly purification box for waste gas treatment of existing coating equipment. The optimization solutions currently on the market are mainly: by setting activated carbon plates and spray mechanisms to absorb waste gas, and by spraying water mist to achieve a certain degree of sedimentation of the gas, but this method is not effective in treating waste gas. There will still be residual waste gas inside the treatment box, and it may flow into the surrounding environment through the gaps in the treatment box, causing pollution to the environment. In response to the above problems, an environmentally friendly purification box for waste gas treatment of coating equipment is proposed, which can achieve all-round waste gas infiltration and dust reduction and prevent waste gas backflow.

[0012] 1. This type of environmentally friendly purification box for waste gas treatment of coating equipment can infiltrate the waste gas when it enters the inside of the waste gas guide pipe by setting a guide pipe and a spraying device. After the waste gas enters the guide pipe, it will overflow through the holes on the surface of the guide pipe, and the nozzle of the spraying device will spray water, which will flow down along the outer surface of the guide pipe and cover the holes. When the waste gas passes through the holes, it will be completely infiltrated by the water flow and will not float to other positions of the purification box, effectively removing particulate matter in the waste gas. The waste gas that has been infiltrated will be absorbed by the outer activated carbon filter plate, thereby improving the filtering effect.

[0013] 2. The environmentally friendly purification box for waste gas treatment of this type of coating equipment is equipped with a water storage tank, which can allow the flowing water to be recovered by the suction pipe and sprayed again for recycling. An air intake mechanism is set to prevent the waste gas from flowing back into the spraying device when it enters the guide pipe. A clamping mechanism is set to freely replace the activated carbon filter plate, which is convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
