Problems solved by technology

The problem of sludge incineration is that the sludge has a high moisture content and strong hydrophilicity, and the water is difficult to remove. Regardless of the natural drying method, mechanical dehydration method or electrostatic dehydration method, the treatment efficiency is extremely low and cannot meet the requirements of sludge at all. Treatment requirements greatly limit the promotion and application of sludge incineration methods

Abstract

The invention discloses a wet sewage sludge combustion furnace which comprises a machine frame, wherein the machine frame is provided with a barrel type furnace body in an inclining manner, and a riding wheel device and a furnace body revolution driving device are arranged between the barrel type furnace body and the machine frame; the machine frame is fixedly provided with a sludge granulation spiral conveyer, and a discharge end of the sludge granulation spiral conveyer stretches into the upper part of the interior of the barrel type furnace body; and the upper end of the sludge granulation spiral conveyer is provided with a steam exhausting device and a granulation discharge hole. The wet sewage sludge combustion furnace provided by the invention can concentrate the sludge in a sludge transport process, the subarid sludge is extruded and granulated through the granulation discharge hole, the sludge grains are driven by the revolving barrel type furnace body to continually roll and dry so as to move to a hearth position, and turn into flammable grains at the heart position, and the combustion of the sludgy is realized. The wet sewage sludge combustion furnace provided by the invention has the advantages that the structure is compact, the sludge concentration drying efficiency is high, an energy source is not wasted, the sludge incineration is thorough, the technical bottle neck of sludge incineration is fully solved, and the wet sewage sludge combustion furnace has great economic and social benefits and popularization and application values.

Description

technical field [0001] The invention relates to a sludge incinerator, in particular to a sludge incinerator for directly burning wet sludge. Background technique [0002] Urban sewage treatment produces a large amount of sludge, papermaking, food, chemical fiber and other enterprises also produce a large amount of sludge in the production process, and anaerobic treatment of garbage also produces a large amount of sludge. Sludge contains a large number of bacteria, insect eggs, heavy metals and organic matter, etc. If it is not handled properly, it will cause new pollution. [0003] In reality, a large amount of sludge is placed in the open air without treatment, which seriously pollutes the environment and takes up a lot of land. The common treatment method of sludge is landfill, which causes secondary pollution to soil and groundwater. Fertilization from sludge is also a method of sludge treatment, but the cost is high, and the heavy metals in the sludge will be absorbed ...
