Problems solved by technology

However, for the flue, the flue gas collected by the flue is transported out by the ash collecting hopper through the double-layer ash unloading valve to the conveyor. Because the dust in the flue is relatively thick and sintered ore is entrained, the valve is easily stuck, resulting in It is difficult to unload ash. After the valve leaks, the dust that has not settled in the flue is raised again, which reduces the dust reduction effect of the flue.

Abstract

The invention discloses a flue water sealing device which comprises a flue body. A dust collecting bucket is arranged on the circumferential wall face of the flue body. The dust collecting bucket is communicated with a flue, and the other end of the dust collecting bucket is connected with one end of a dust discharging pipe. The flue water sealing device further comprises a water sealing zipper machine and a belt conveyor. The output end of the water sealing zipper machine is located above the belt conveyor, and the water sealing zipper machine is composed of a water groove and a zipper. The zipper is installed at the bottom of the water groove, and the other end of the dust discharging pipe is inserted in the water groove of water sealing zipper machine. The processing efficiency of dust of smoke in the flue is improved, and therefore the phenomenon of clamping of a valve is avoided.

Description

technical field [0001] The invention relates to a flue water sealing device. Background technique [0002] During the coal-filling period during the operation of the coal-fired boiler, due to the sudden evaporation and cracking of the volatile matter in the coal, a large amount of combustible gas is produced, and due to the insufficient furnace temperature and oxygen supply conditions, a large amount of black smoke is produced, and the black smoke contains a large amount of For combustible solids and combustible gases, the exhaust gas temperature of general boilers is mostly at 200-250°C, which not only pollutes the air quality, but also causes a lot of energy waste. To control flue gas pollution, the flue gas is generally removed through the flue to remove large dust particles, and then dust is removed by the electrostatic precipitator. However, for the flue, the flue gas collected by the flue is transported out by the ash collecting hopper through the double-layer ash unl...
