Sludge resource treatment device and method for treating sludge

Abstract

The invention discloses a sludge resource treatment apparatus and a sludge treatment method using the same. The apparatus comprises a collecting filter, a sludge conveying device, a waste heat drying column, a cyclone separator, a rotary kiln, a draught fan, an airheater, a gathering tank, a deodorizing tower, a gas-liquid separator and a chimney, wherein the sludge conveying device, the waste heat drying column, the cyclone separator, the draught fan, and the deodorizing tower are successively connected through pipelines. When the sludge is anhydrated by the sludge resource treatment apparatus, the sludge generated by a sewage treatment plant is treated with gravity settlement to filter free water, dried with waste heat from the rotary kiln in the waste heat drying column and enters intothe rotary kiln to realize drying or sintering of the sludge; stink, flue gas and water vapor generate during the process is guided into the deodorizing tower for treatment by the draught fan. The treatment apparatus of the present invention has a compact and stable structure, small land occupation, is convenient for maintenance, and can be prepared into container overlap to facilitate carrying and save space.

AI Technical Summary

Benefits of technology

This patented technical solution involves providing an apparatus called a filtrating tank used in treatments on sewage or industrial wastes. It has pits made up of filters covering its borders and pools filled with filtering materials like sand or gravel to remove any remaining liquid before disposal. When this material becomes saturated due to excess moisture content inside them, it falls down through holes onto another layer where other solid matter can be separated based upon their size. Dryers then separate these solids from liquor while still warm enough to prevent clump formation. These techniques help save power when processing large amounts of dirty fluid at once.

Problems solved by technology

This technical problem addressed in these documents relates to the development of effective techniques for efficiently handling and utilizing excessive amounts of municipal wastes generated during production processes like civil engineering projects. Current solutions involve expensive and energy intensive physical facilities, leading to environmental concerns. There have been attempts made towards developing new ways to effectively dispose of various types of residues produced throughout industry practice without causing negative impacts upon their surroundings.
