Problems solved by technology
[0003] The flue gas produced by the existing kiln enters the confluence bin after leaving the kiln, where the flue gas is blown and cooled by cooling wind to reduce its temperature to meet the tolerance requirements of the steel flue, and then passed through The steel flue enters the dust removal system, but the cooling device has a single means and cannot well control the temperature entering the dust removal room
Due to the limited effect of supplementary air cooling of the exhausted flue gas from the kiln, it is also impossible to cooperate with the dust removal and cooling device to control the temperature of the flue gas entering the dust removal chamber to achieve the expected effect, so it is particularly important to solve this type of problem

Embodiment Construction
[0014] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.
[0015] according to figure 1 , 2 As shown in . The flue 3 leads to the dust removal system. The steel flue 3 is covered with a water-cooling sleeve 4, and one end of the water-cooling sleeve 4 near the exhaust hole is provided with a water inlet 5. The water inlet 5 passes through a ball valve 6 and The cooling water joint 7 is connected to the water inlet pipe 8; a water outlet 9 is provided at one end of the water cooling sleeve 4 close to the dust removal system, and the water outlet 9 is connected to the water outlet pipe 10 through the ball valve 6 and the cooling water joint 7. A thermocouple is arranged in the steel flue 3, and the flue gas temperature in the steel flue is c...

The invention discloses a cooling device for the flue of a TFT-LCD glass kiln. The cooling device comprises an exhaust hole formed in the wall of the kiln, wherein a steel flue leading to a dust removal system is arranged on the exhaust hole and is sleeved by a water cooling jacket; a water inlet is formed in the end, close to the exhaust hole, of the water cooling jacket; the water inlet is connected with a water inlet pipe through a ball valve and a cooling water joint; a water outlet is formed in the end, close to the dust removal system, of the water cooling jacket; and the water outlet isconnected with a water outlet pipe through another ball valve and another cooling water joint. According to the invention, the water cooling jacket is arranged out of the steel flue to reduce the temperature of flue gas.
Description
technical field [0001] The invention relates to the technical field of TFT-LCD glass production, in particular to a TFT-LCD glass kiln flue cooling device. Background technique [0002] The temperature of the furnace for producing TFT-LCD glass reaches above 1600°C, which is more than 100°C higher than that of ordinary glass furnaces. After the flue gas enters the flue, the temperature of the flue gas is very high, which can reach above 1000°C. , The nitrogen in the air reacts with oxygen to produce a large amount of nitrogen oxides. Nitrogen oxides not only pollute the atmosphere, but also cause harm to the human body. [0003] The flue gas produced by the existing kiln enters the confluence bin after leaving the kiln, where the flue gas is blown and cooled by cooling wind to reduce the temperature to meet the tolerance requirements of the steel flue, and then passed through The steel flue enters the dust removal system, but the cooling device has a single means and canno...
