A dust purification system

Abstract

The invention provides a dust purifying system. The dust purifying system comprises a water washing tank, an impurity storage tank, a positioning rack, an isolation rack, a baffle, a liquid separating mechanism and a control mechanism, wherein the water washing tank and the impurity storage tank are mounted on the positioning rack, and the impurity storage tank is located below the water washing tank; the baffle is mounted in the water washing tank and provided with a plurality of ventilation through holes; the liquid separating mechanism comprises a drive device and a liquid isolating plate, the liquid isolating plate is movably mounted in the water washing tank and located below the baffle, the drive device is in drive connection with the liquid isolating plate and drives the same to move vertically, and the edge of the liquid isolating plate can be abutted against the inner wall of the water washing tank by the movement of the liquid isolating plate; the water washing tank is provided with a gas inlet, a gas outlet, an impurity outlet and a liquid guide port; an impurity discharge door and a spraying device are mounted on the water washing tank; the impurity storage tank is provided with an impurity inlet; the control mechanism comprises a control device and a light transmittance detecting device. The dust purifying system is convenient to use, good in treatment effect on tail gas generated by slag treatment and capable of working continuously.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a dust purification system. Background technique [0002] At present, most of the garbage disposal methods in our country are landfills. Because domestic garbage in our country has the characteristics of low calorific value and high water content, landfills are used to dispose of garbage. In addition to the unpleasant smell produced during the landfill process, the leachate produced It is a difficult problem of landfill technology. The generation of leachate seriously pollutes groundwater and endangers human survival. [0003] The heat treatment method is relatively easy to treat the heat treatment products that pollute the environment. Even so, the tail gas that pollutes the environment will be produced during the slag treatment process, but the tail gas from the slag treatment cannot be effectively purified at present.

[0002] At present, most of the garbage disposal methods in our country are landfills. Because domestic garbage in our country has the characteristics of low calorific value and high water content, landfills are used to dispose of garbage. In addition to the unpleasant smell produced during the landfill process, the leachate produced It is a difficult problem of landfill technology. The generation of leachate seriously pollutes groundwater and endangers human survival.

[0003] The heat treatment method is relatively easy to deal with the heat treatment products that pollute the environment. Even so, the tail gas that pollutes the environment will be produced during the slag treatment process, but at present, the tail gas from the slag treatment cannot be effectively purified.
