TECHNICAL FIELD

[0001] The utility model relates to waste gas treatment technical field, concretely is a kind of metal smelting pot waste gas treatment device. BACKGROUND

[0002] In the metal smelting process, smelting pot will produce a large amount of harmful gas (such as sulfur dioxide, carbon monoxide etc.) and dust containing waste gas. These waste gases, if not treated directly discharged, will cause serious pollution to the environment. In the prior art, although some waste gas treatment devices can treat harmful gases in waste gas, but most lack the pretreatment filtering function of dust in waste gas.

[0020] As a preferred scheme of the utility model, the device housing is internally provided with a combustion chamber at an upper end, and the combustion chamber is provided with an exhaust pipe at an upper end.

[0021] Compared with the prior art, the utility model has the beneficial effects that:

[0022] 1、In the utility model, the dust is efficiently pretreated: after the waste gas enters the device through the air inlet pipe, it is first filtered by the dust filtering plate, effectively removing large particles of dust in the waste gas. This pretreatment method can significantly reduce the burden of the subsequent treatment unit and improve the efficiency and stability of the entire waste gas treatment system;

[0023] 2、The dust filtering plate is automatically cleaned: through the transmission of the rotating shaft and the gear, the dust filtering plate rotates synchronously with the brush during rotation, continuously cleaning the surface of the dust filtering plate. This design can effectively prevent dust from accumulating on the surface of the dust filtering plate and avoid clogging of the dust filtering plate, thereby maintaining the filtering efficiency of the dust filtering plate and prolonging its service life;

[0024] 3、The maintenance cost is reduced: since the dust filtering plate can be automatically cleaned, the frequency and workload of manual cleaning are reduced, the maintenance cost of the equipment and the labor intensity of the operating personnel are reduced. At the same time, the automatic cleaning function also helps to improve the continuous operation time of the equipment and reduce the downtime caused by equipment failure.
