The Ecological Drying System for a Sludge which has high percentage of water content}

The present invention relates to an eco-friendly drying system of high water content sludge which is pulverized and transported by a cylinder penetrating the inside of a combustion chamber heated through a combustion device. It relates to an eco-friendly drying system of high water content sludge that can be treated with

Various industrial wastes are increasing due to the improvement of living standards according to the development of the industry.In particular, organic matter including food waste or industrial waste containing water contains moisture and harmful gases during decomposition. The wastewater is separated and collected, and the high content sludge collected is difficult to process, and in the case of the decomposition process by microorganisms, a separate catalyst (microorganism) is required according to the throughput of the organic material to be treated. It takes a long time due to the decomposition treatment is an inefficient utilization method, there is a problem that the maintenance cost is increased due to the acquisition of a professional manpower for the management of harmful gases generated during the organic material treatment process.

In addition, when it is mixed with rainwater or groundwater from the outside of the landfill, it may contaminate rivers and drinking water sources. Organic matter contains moisture, and as the weight increases with volume, the transport and treatment costs to the landfill area are increased. Odor and sewage from landfills not only cause serious environmental pollution or soil pollution, but also deal with long-term plans or large amounts of waste as a means of neglect, not a process of complaints and disposal surrounding landfill selection. There are realistic constraints on this.

When the high water content sludge is treated by incineration, the sludge is not incinerated until the moisture is evaporated, and when water vaporizes and diffuses in the air, there are problems such as pollution and environmental hormones. Existing high water content sludge treatment is exhausting high facilities and enormous energy sources and its effectiveness has not been verified.

The present invention has been made in order to solve the above problems, high-water content sludge eco-friendly that can effectively separate and treat the water, gas and organic matter by placing and adding a complete combustion structure of the water treatment and the harmful gases generated efficiently We want to have a drying system.

In addition, by recycling the harmful gas vaporized through the cylinder treated with high content sludge to the combustion chamber to induce complete combustion at high heat, a series of processes to automatically collect the dried sludge in the cylinder organically constitute a high content sludge The company aims to have a high-water content sludge eco-friendly drying system that allows all processes to be automated.

This removes moisture and gas from high water content sludge so that organic matters from which water and gas have been removed can be automatically collected, and the generated gas is again used as a heat source in the combustion chamber for water removal of food. In order to increase the efficiency, and to provide a partition in the combustion chamber to increase the residence time in the combustion chamber in the heat of combustion and to specify the location of the partition wall to provide a high-water content sludge eco-friendly drying system that can automatically collect the ash generated in the combustion chamber.
