Smelting furnace waste heat recovery device for glass production and using method thereof

Abstract

The invention relates to the technical field of waste heat recovery, in particular to a smelting furnace waste heat recovery device for glass production and a using method thereof. The smelting furnace waste heat recovery device comprises a glass smelting furnace, the glass smelting furnace further communicates with a cooling water supplementing mechanism and a hot water supplementing mechanism, and the hot water supplementing mechanism comprises a water storage tank and a second water pump; the hot water supply mechanism can adjust the temperature of cooling water subjected to heat exchange so as to guarantee normal domestic hot water, after the water enters the water storage tank, the hot water supply mechanism can start to work, the temperature sensor can detect the water temperature, and when the water temperature is too low and cannot meet the heat supply requirement, the motor can work, and the heating ring heats the water; and the rotating rod drives the stirring rod to rotate,the temperature of water can be more balanced, when the water temperature is too high and cannot meet the heat supply requirement, the electromagnetic valve can be opened, cold water can enter the inner side of the water storage tank to neutralize the too high water temperature, and therefore it is guaranteed that the water on the inner side of the water storage tank is at a proper temperature.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to a furnace waste heat recovery device for glass production and a method for using the same. Background technique [0002] At present, glass melting furnaces mainly adopt two methods of flame melting and electric melting. No matter which method is used for melting, heat energy input is required. The melting part needs a high temperature of 1300°C to 1500°C to melt the glass raw material and melt the pool. The wall is made of high corundum brick material as the container, and the outside is kept insulated by insulation bricks, clay bricks and other materials. The temperature of the outer surface of the pool wall is between 80°C and 180°C according to the different stages of furnace use, and the electrode cooling water of the glass electric melting furnace will also be A large amount of heat is taken away, and the energy cannot be fully utilized, which will cause environm...
