Description

Technical Field

[0001] The utility model relates to the technical field of substrate glass manufacturing, in particular to an improved substrate glass smoke treatment tower inspection window. Background Art

[0002] During the production of liquid crystal glass, melting glass in a tank furnace generates waste gas. This waste gas must be treated through urea spraying, SCR treatment, cooling towers, absorption towers, fans, wet electrostatic precipitators, chimneys, and other processes or equipment to meet standards before it can be discharged. During the flue gas treatment process, the flue gas must first be sprayed through the cooling tower. After long-term use, the nozzles of the spray components in the cooling tower are prone to clogging, affecting the spraying effect. The cooling tower must be opened, and operators must enter the tower to replace the nozzles. After spray cooling, the flue gas enters the absorption tower, where impurities in the flue gas are absorbed by the ball rings inside the absorption tower. The ball rings need to be replaced after a period of use, and operators also need to enter the tower for inspection and maintenance.

[0003] Both the cooling tower and the absorption tower are equipped with inspection windows, through which operators enter the tower for inspection and maintenance. The existing inspection window structure is independent of the cooling tower and the absorption tower. Operators need to remove the inspection window to expose the window. The inspection window itself is large and heavy, making it inconvenient to disassemble and install, and difficult for a single person to operate. Utility Model Content
