Description

Technical Field

[0001] The utility model relates to the technical field of carbonization furnaces, in particular to an activated carbon carbonization furnace tail gas treatment device. Background Art

[0002] There are three types of carbonization furnaces: ordinary type (can only be used to produce charcoal, cannot collect gas); wood carbonization equipment (used to carbonize branches, wood blocks, coconut shell blocks, scrap blocks in furniture factories, etc. This equipment can be equipped with a gasification furnace device to recycle gas into fuel gas for the carbonization furnace to use or for other purposes); carbon powder production line (a machine used to produce carbon powder, which can carbonize rice husks, sawdust, and bamboo dust into carbon powder, which can be processed into activated carbon).

[0003] According to a Chinese patent document with announcement number CN218475040U, an activated carbon carbonization furnace exhaust gas treatment device is disclosed, which includes a shell, a support net is fixedly connected to the inside of the shell, a fuel pipe is fixedly connected to the inside of the support net, and an electric burner is fixedly connected to the outside of the fuel pipe; the carbonization exhaust gas is introduced into the interior of the dust removal chamber through a conduit, and is separated by liquid water to absorb solid particles and dust. At the same time, the combustible gas composed of carbon monoxide, methane, and oxygen in the carbonization exhaust gas is separated by liquid water and then transported to the fuel pipe for recycling through a combustible gas recovery pipe. The filtered liquid water passes through the porous filter membrane plate and flows into the dust removal chamber again through a one-way reflux pipe. The movement of the waterproof coil drives the elastic push plate to move under the telescopic action of the electric rod to drive the solid particles and dust filtered and separated on the surface of the porous filter membrane plate to be discharged through the slag discharge port, thereby realizing the green recycling treatment of the carbonization exhaust gas.

[0004] Based on the search of the above patents and in combination with the exhaust gas treatment device in the prior art, it is found that when the above device is in use, the exhaust gas is transported into liquid water, so that the impurity particles in the exhaust gas are mixed with the liquid water, and the combustible gas composed of carbon monoxide, chlorine and oxygen in the exhaust gas is separated from the liquid water and recovered for full combustion again, thereby achieving green recycling treatment. However, in actual use, due to the impurities in the liquid water, during the process of extraction and injection through the extraction pipe and the injection disk, the impurities are likely to cause accumulation in the injection disk. Due to the action of the electric pump, the extraction and injection speeds are relatively fast, which will cause a certain amount of impurity particles to accumulate quickly in the injection disk. Long-term use will cause the impurities to accumulate together, resulting in clogging of the injection disk, and later cleaning and replacement will be more troublesome, thereby reducing practicality.
