Detailed ways

As shown in the figure; the utility model includes a glass kiln, which is characterized in that it also has a flue gas waste heat regenerator. The flue gas waste heat regenerator is composed of a left flue gas waste heat regenerator and a right flue gas waste heat regenerator. The left flue gas waste heat regenerator is composed of left gas regenerator 2-1 and left air regenerator 2-2, and the right flue gas waste heat regenerator is composed of right gas regenerator 3-1 and right air regenerator 3 -2 structure, the left gas regenerator 2-1 and the left air regenerator 2-2 communicate through the gas port, and the right gas regenerator 3-1 and the right air regenerator 3-2 also communicate through the gas port; two gas Heat-absorbing materials are placed in the regenerator 2 and the two air regenerators 3 (heat-absorbing materials are selected, refractory heat-absorbing materials such as dolomite, magnesia bricks, etc.); It is two gas branch pipelines, wherein one gas branch pipeline 4-1 communicates with the left burner port 6-1 of the glass melting chamber 6 of the glass kiln 1 through the left gas regenerator 2-1, and the other gas branch pipeline 4-1 2 The right gas regenerator 3-1 communicates with the right flame outlet 6-2 of the glass melting chamber 6 of the glass furnace 1; the flue gas outlet of the left air regenerator 2-2 and the right air regenerator 3-2 The left flue 2-4 and the right flue 3-4 communicate with the chimney 7 of the glass kiln through the flue gas exchanger 9 respectively, and the air inlets of the left air regenerator 2-2 and the right air regenerator 3-2 A blower 8 is installed at each place, the hot air outlet of the left air regenerator 2-2 communicates with the glass melting chamber 6 flame outlet 6-1, and the hot air outlet of the right air regenerator 3-2 communicates with the glass melting chamber 6 flame outlet 6- 2 connected.

Working method: First, the flue gas switch works, closes the left flue 2-4, and opens the right flue 3-4. At the same time, the gas switch works, so that one of the gas branch pipes 4-1 is connected to the gas, and the other gas branch pipe 4-2 is closed. The gas enters the left burner port 6-1 through the left gas regenerator, burns in the glass melting chamber, and the glass melts. The hot flue gas generated in the room enters the right gas regenerator and right air regenerator through the right flame vent 6-2, the waste heat in it is absorbed by the heat-absorbing material, and the flue gas in it passes through the right flue 3-4 through the flue gas exchanger Into the chimney discharge. After 20 minutes, the gas switch closes one gas branch pipe 4-1, and opens another gas branch pipe 4-2 (the flue gas switch also works, close the right flue 3-4, open the left flue 2-4), and the gas enters After the right gas regenerator, it absorbs the heat of the heat-absorbing material in the right gas regenerator to become hot gas. At the same time, the blower 8 works, and the cold air enters the right air regenerator to absorb the heat of the heat-absorbing material and become hot air. After being mixed with hot coal gas, it enters the right burner port 6-2 and burns in the glass melting chamber, and the hot flue gas after combustion enters the left gas regenerator and the left air regenerator for heat storage. Working in this cycle, the hot air and hot gas are always mixed and burned to achieve the purpose of energy saving. The air switch (gas switch, flue gas switch) is a device used to change the gas flow direction of the system. The exchange cock, the exhaust gas pan weight rod and the air cover are driven by pull bars, levers, chains, etc. to switch regularly to change the gas flow. , the direction of flow of air or exhaust gas. the
