[0002] The construction industry cannot do without waterproof membranes. With the continuous advancement of science and technology, modified asphalt waterproof membranes are becoming more and more popular and are widely used. When mixing materials, the current production of modified asphalt waterproof membranes requires mixing high-temperature asphalt with room-temperature modification additives, which results in a large amount of waste gas that is difficult to collect and treat. Therefore, a waste gas purification device is required to purify the waste gas. However, the existing waste gas purification device for the production of modified asphalt waterproof membranes is difficult to perform a multi-stage purification process on the waste gas, resulting in the waste gas purification not being thorough enough and still failing to meet environmental indicators. At the same time, the existing waste gas purification device for the production of modified asphalt waterproof membranes cannot recycle purification resources, resulting in a waste of more available resources in the waste gas purification process. Therefore, a multi-stage waste gas purification device for the production of modified asphalt waterproof membranes is needed to solve the above problems. Summary of the invention

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a humidifying tower, a purification box, an electrostatic condensation box, a desulfurization tower and a filter screen. When the exhaust gas enters the humidifying tower through the air inlet pipe, the humidifying tower can spray water to remove sulfur from the exhaust gas, so that the sulfur-containing wastewater can be introduced into the purification box by a water pump for purification. Subsequently, the guiding mechanism is started to cause the purified water resources in the purification box to enter the humidifying tower through the guide pipe, so as to achieve the purpose of recycling water resources.
