[0002] The pool furnace needs to use compressed air for cooling in the production of substrate glass, to prevent safety accidents caused by glass liquid leakage. The compressed air is transported from the kinetic station to the terminal pipeline of the pool furnace, and is affected by pressure reduction and temperature change. The water contained in the compressed air accumulates in the terminal pipeline. When the water in the pipeline accumulates to a certain amount, it will be sprayed out to the pool furnace with compressed air. The pool furnace is in a high temperature state, and the water will cause uneven heating of the refractory material and cracks. In severe cases, it will affect the service life of the pool furnace. Based on the above situation, the accumulated water needs to be drained. The existing drainage method is to install a valve on the terminal pipeline for regular drainage. This method will affect the pressure of compressed air when draining, and will affect the cooling of the site. Therefore, it is of positive significance to find a device for compressed air drainage at the end of the pool furnace. SUMMARY
