Sintering smoke dust treating device

Abstract

The invention discloses a sintering smoke dust treating device. The sintering smoke dust treating device comprises a vacuum box, a large flue, a fan, a silencer, a flue water sealing device, a water-sealed chain-driving machine and a belt conveyor, wherein the output end of the vacuum box is connected with the input end of the large flue; the output end of the large flue is connected with the input end of the fan; the output end of the fan is connected with the input end of the silencer; the flue water sealing device is connected between the large flue and the fan and comprises a flue body; an ash collecting hopper is arranged on the circumferential wall surface of the flue body and communicated with the flue; the other end of the ash collecting hopper is connected with one end of an ash discharging pipe; the output end of the water-sealed chain-driving machine is positioned above the belt conveyor; the water-sealed chain-driving machine consists of a water tank and a zipper; the zipper is mounted at the bottom of the water tank; the other end of the ash discharging pipe is inserted into the water tank of the water-sealed chain-driving machine. According to the device, the treatment efficiency of the smoke dust of fume passing through the flue is improved, and the phenomenon of valve sticking is avoided.

Description

technical field [0001] The invention relates to a sintering smoke treatment device. Background technique [0002] During the production process of the sintering process, especially when sintering finely ground ore powder, a large amount of smoke and dust will be generated. The structure of the treatment device currently used for the smoke and dust is: including a vacuum box, a large flue, a fan, a muffler, and the output end of the vacuum box It is connected to the input end of the large flue, the output end of the large flue is connected to the input end of the fan, and the input end of the fan is connected to the input end of the muffler. During processing, the flue gas discharged from the boiler first enters the vacuum box, After passing through the vacuum box, it enters the large flue, where the dust removal is carried out to remove the larger dust particles. The flue gas is drawn out by the fan, and the noise is reduced by the muffler, and then discharged from the chimn...

Problems solved by technology

However, for the large flue, the flue gas collected by the large flue is transported out of the ash collecting hopper through the double-layer ash discharge valve to the conveyor. Because the dust in the flue is relatively thick and sintered ore is entrained, the valve is likely to be stuck , resulting in difficulty in ash unloading, after the valve leaks, the dust that has settled in the flue is raised again, reducing the dust-reducing effect of the flue
