[0002] Polystyrene granules, also known as expanded polystyrene foam granules or expanded polystyrene granules, are made by expanding and foaming expandable polystyrene resin beads as the base material. The production of polystyrene granules generates a large amount of waste gas. In order to prevent the waste gas generated during the production of polystyrene granules from being directly discharged into the atmosphere, it is necessary to purify the waste gas through a spray tower before discharging it into the atmosphere to prevent environmental pollution.

[0003] However, existing spray towers for exhaust gas purification are inconvenient to maintain when using the spray equipment installed inside the tower, especially when the spray nozzles are damaged, it is inconvenient to replace them. Furthermore, when it is necessary to replace the packing material in the absorbent layer of the spray tower that is used to purify exhaust gas, the replacement is usually done through a viewing window on one side of the packing layer, which is time-consuming and labor-intensive.

A fixing member is symmetrically installed on one side of each of the two protective covers, and a fixing buckle is threaded into the fixing member and threadedly engaged in the spray tower.

[0006] Preferably, the spray tower has two mounting slots on one side, each containing a filter frame. Slide rails are fixedly installed on both sides of the bottom surface of each mounting slot, and sliding sleeves are fixedly installed on both sides of the bottom surface of each filter frame. The sliding sleeves are slidably mounted on the slide rail surface. A filter screen is fixedly installed on the bottom surface of each filter frame, and a positioning element is fixedly installed in the middle of one side of the bottom surface of each filter frame. A positioning buckle is threaded into the positioning element and threadedly engaged within the spray tower.
