The production line process comprises the following steps: the glass is horizontally conveyed by a roller way in the feeding device, enters a heating furnace at a constant speed for heating, and is rapidly cooled under a certain wind pressure for tempering after coming out of the heating furnace and moving to a quenching cooling section (cooling air grid). Wherein, the cooling process has important influence on the quality of the toughened glass. Under certain conditions, the lower the temperature of the inlet air of the toughened glass is, the faster the toughening speed is, so that the mechanical strength of the glass is improved. If dust exists in the air, the dust attached to the glass will affect the quality of further processed products, such as surface printing of toughened glass. The toughened glass production line air inlet is required for providing compensation air for the high-pressure fan, if the automatic air taking port of toughened glass is in the workshop, and many heat sources in the production workshop will lead to the air inlet temperature higher, and dust and waste gas in the production process constantly accumulate and lead to dust, oil mist, the waste gas content in the workshop higher, lead to the dust content in the air of air inlet to exceed the standard.
