Totally-enclosed storage and pretreatment device for co-treating industrial sludge with cement kiln

Abstract

The invention discloses a totally-enclosed storage and pretreatment device for co-treating industrial sludge with a cement kiln. A liquid outlet end of a pump is communicated with a feeding end of a pulverizer, a discharging end of the pulverizer is connected with an underground silo, a feeding end of a fine aggregate concrete pump extends into the underground silo, a discharging end of the fine aggregate concrete pump extends to a position above a first conveyor belt, a thermal insulation vibrating screen is arranged above the first conveyor belt, an unloading end of the first conveyor belt is located above a feeding port of a stirring barrel, a roller is rotationally connected to a discharging port of the stirring barrel, a second conveyor belt is located below the roller, and a gas extractor is connected with a high-energy ion generator and sends gas in the underground silo into the high-energy ion generator for deodorization. The totally-enclosed storage and pretreatment device has a good use effect, water in the industrial sludge can be consumed effectively, calcium content can be increased effectively, heat emitted by a reaction can effectively remove odor and bacteria, enclosed storage and leakage prevention of the industrial sludge are realized effectively, the underground silo can be constructed in a quarry, and waste of cultivated land resources is avoided.

Description

Technical field: [0001] The invention relates to a fully enclosed storage and pretreatment device for co-processing industrial sludge in a cement kiln. Background technique: [0002] Industrial sludge refers to the turbid muddy substances produced by industrial wastewater after harm reduction treatment. The composition is relatively complex, and most of them are hazardous solid wastes, which must be treated properly. The pollution consequences caused by them are far greater than ordinary solid wastes. At present, the commonly used treatment or disposal methods of sludge mainly include sanitary landfill, sea reclamation, composting and incineration. Among them, sanitary landfill needs to occupy a large amount of land resources for a long time, which violates the scientific concept of sustainable development, and often pollutes the ecological environment around the landfill due to the leakage of harmful ions; Select the seabed with suitable distance and depth, and close the s...

Problems solved by technology

Among them, sanitary landfill needs to occupy a large amount of land resources for a long time, which violates the scientific concept of sustainable development, and often pollutes the ecological environment around the landfill due to the leakage of harmful ions; Select the seabed with suitable distance and depth, and close the sludge to landfill, but it only converts land pollution into marine pollution

Selecting appropriate sludge for composting can effectively improve soil composition structure, increase organic matter content, and improve soil fertility. However, industrial sludge contains high levels of harmful impurity ions and heavy metal elements. Once absorbed by plants and enters the food chain cycle, it will Seriously endanger the health of humans and other living things

At present, the incineration method is widely used in the treatment of solid waste, which can realize harmless and reduction treatment to the maximum extent. The treatment method is relatively simple, but the disposal cost is very high, and the water content of industrial sludge is relatively large, generally at 80 %, the calorific value is low and not easy to burn, often resulting in a large waste of calorific value
