Description

TECHNICAL FIELD

[0001] The utility model relates to dangerous waste treatment technical field more specifically, it relates to a dangerous waste incineration chamber's dust discharging unit in. BACKGROUND

[0002] Now environmental protection is increasingly valued, and the treatment of hazardous waste has become a global problem. Hazardous waste, including chemical waste, medical waste, industrial waste, etc. may pose a serious threat to the environment and human health due to the presence of harmful substances. Therefore, special treatment methods are required. Incineration technology, as an efficient and volume-reducing treatment method, is widely used in the treatment of hazardous waste. The hazardous waste incinerator is the core equipment of the incineration technology, and its design and operation directly affect the incineration efficiency, flue gas purification effect, and ash disposal.

[0003] For example, the authorized announcement number CN208671006U discloses a new garbage recycling incineration chamber, which comprises an incineration chamber main body, a radiator and a base. A dust collection chamber is connected to the right side of the incineration chamber main body. A chimney is fixedly connected above the dust collection chamber. A purifier is embedded at the junction of the dust collection chamber and the chimney. A garbage inlet is provided on the lower surface of the incineration chamber main body. A dust collector is embedded in the lower part of the incineration chamber main body. A dust outlet is provided on the lower part of the dust collector. A stirrer is embedded in the dust collector. The Z-shaped stirring rod rotates clockwise to make the ash flow out of the dust outlet. The long blade evenly distributed in the stirrer can stir the ash in the dust collector.
