Problems solved by technology

Combustibles in the coal ash reach 40% to 50%, and the coal is not fully burned, which increases the daily coal consumption, which is 3.2 to 3.5 tons per day, resulting in ineffective energy consumption
Frequent picking of furnace bars will lead to unstable furnace temperature, resulting in abnormal melting material liquid, material quality cannot be guaranteed, and normal production will be affected

[0026] A third layer of flue (12) is arranged on one side of the furnace foundation (20) top of the body of furnace, and a second layer of flue (11) is arranged on the top of the third layer of flue (12), and the third layer of flue (12) is connected to the The second layer of flue (11) is connected, the upper part of the second layer of flue (11) is provided with the first layer of flue (10), the second layer of flue (11) is connected with the first layer of flue (10) A small chimney (21) is set on one side of the top of the first layer of flue (10), and the small chimney (21) is connected with the first layer of flue, and several air storage chambers are set on one side of the small chimney (21) ( 22), the upper part of the air storage chamber (22) is provided with several crucibles (8). One end of the flue heat displacer (18) is connected with one side of the third-layer flue (12), and the other end of the flue heat displacer (18) is connected with the lower end of the chim...

Embodiment 2

[0033] Inside the heat displacer (15), two flue heat displacers (18) are relatively parallelly arranged along the heat displacer (15), and the two flue heat displacers (18) are arranged relatively parallel to each other.

[0034] One end of the heat exchanger (15) is connected to one side of the third layer flue (12), and passes through the second layer flue (11) and the first layer flue (10) and the air storage chamber (22) Connected, the other end of heat exchanger (15) is connected with one end of air inlet (19) and chimney (17).

[0035] The upper part of the other end of the heat displacer (15) is provided with a chimney suction force detector (13), a flue side temperature instrument (14) and an air inlet (19), a chimney suction force detector (13) and a flue side Thermometer (14) is connected with instrument control box (16).

[0036]The secondary air enters the heat displacer (15) from the air inlet (19) and performs heat displacement with the flue heat displacer (18)....

Embodiment 3

[0038] The heat energy generated by the furnace (2) is converted into hot air and then enters the melting chamber (6) to heat and melt the glass material liquid in the crucible (8). After heating, part of the waste gas passes through the small chimney (21), the first layer of flue (10 ), the second layer of flue (11), the third layer of flue (12) and the flue heat displacer (18), exhaust gas is removed by the chimney (17); the secondary air enters the heat from the air inlet (19) The displacer (15) performs heat displacement with the flue heat displacer (18), and the secondary air rotates along the heat displacer (15) and passes through the third layer of flue (12), the second layer The flue (11) and the first layer of flue (10) enter the air storage chamber (22), and the heat-displaced secondary air enters the pre-combustion burner (4) from the air storage chamber (22) and mixes and burns with the coal gas to improve The temperature of melting chamber (6) reciprocates, as sho...

Abstract

A glass smelting crucible furnace with exhausting waste gas in forward direction and recovering heat energy in reverse direction features that its combustion box above grate has ash layer, fire layer, coal layer and air layer, its combustion chamber is composed of pre-burning flame nozzle and smelting chamber, and the fume flow through three fle layers, heat exchanger, and venting from chimney. Its advantages are high and stable furnace temp., low coal consumption no black smoke, and no environmental pollution.

Description

technical field [0001] The invention relates to a special crucible furnace for glass production, in particular to a double-flow glass crucible furnace. Background technique [0002] The fuel used in most industrial furnaces is coal. At present, the structure of glass crucible furnaces and furnaces in other industries mostly adopts old-fashioned structures. Therefore, the traditional glass crucible furnaces have the following situations in use: [0003] The structure of the glass crucible furnace is relatively simple, with two layers of flue and a layer of air in the middle. Mainly use the primary air to enter the fire layer from the bottom of the furnace to support combustion, speed up the combustion speed of the fire layer, and increase the furnace temperature by increasing the suction force of the chimney. Due to the high speed of the exhaust gas, the temperature of the exhaust gas is too high, generally above 1000°C. Therefore, the chimney will burn red, ignite, and burn...
