Abstract

Provided are a system (100) and a method for recycling waste heat from a drying machine. The system for recycling the waste heat from a drying machine comprises an exhaust emission chimney (11), a water storage tank (12), a drain pipe (13), a sprinkler (14), a rotating stream tray (15), a wire mesh mist eliminator (16), a water replenishing device (17) and a hot water utilization device (18). The system (100) and the method for recycling the waste heat from a drying machine transform the water vapor in the exhaust from the drying machine into hot water and recycle the hot water into a batching system so as to achieve the regeneration and utilization of waste water so that the temperature of slurry can be increased while energy and water resources are saved, wherein same facilitates the smooth drying process of gypsum boards, reduces the energy consumption in the drying process, is beneficial for production and can effectively reduce production costs.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to the technical field of waste heat recovery and utilization of drying machines. Background technique [0002] The drying process of gypsum board consumes a lot of heat, and in winter, the weather is cold and the temperature is low, so the production energy consumption is high, resulting in low production line speed. In a cold environment, the temperature of the slurry is low, resulting in a low temperature of the formed gypsum board, and a large temperature difference will be generated when it enters the dryer, causing a layer of liquefied water to condense on the surface of the gypsum board quickly, thus forming a layer of liquefied water on the surface of the gypsum board. There will be "watermark" and "hemp pit" on the paper surface, which will seriously affect the appearance quality of the product, and even affect the strength of the gypsum board; and because the temp...
