A hydrothermal drum high temperature composting reactor

Abstract

The invention discloses a hydrothermal roller high temperature compost reactor. The reactor comprises a main reaction tank, and further comprises a gas supply device, wherein a gas distributing chamber and an exhausting valve are respectively arranged at both ends of the main reaction tank, a temperature control water layer is arranged on the inner wall of the main reaction tank, a plurality of stirring teeth are arranged on the inner wall of the temperature control water layer, and the stirring teeth are communicated with the exhausting valve through the gas distributing chamber at the same time; a water inlet valve and a return valve are arranged on the outer wall of the main reaction kettle; three temperature sensors are arranged inside the main reaction kettle; a rotary shaft is arranged in the middle of the gas distributing chamber; the air supply device comprises an air compressor which is connected with the gas distributing chamber through a pipeline; a driving device far from one end of the gas distributing chamber is arranged on the main reaction tank. The reactor disclosed by the invention has high controllability such as controlled temperature and oxygen supply, and can improve the sludge composting efficiency, enhance the fertilizer efficiency of composting products and reduce the risk of secondary pollution.

Description

technical field [0001] The invention relates to a novel sludge composting device, which is a relatively high controllable reactor. Background technique [0002] With the acceleration of the urbanization process, the sewage treatment system has been continuously improved and increased, and the amount of urban sewage sludge has continued to increase. Although the sludge treatment system has continued to improve, due to the imperfect planning and management of our country, the lack of comprehensive understanding, and insufficient capital investment have led to sludge treatment. The technology is backward. Sludge is an extremely complex heterogeneous body composed of bacterial cells, inorganic particles, organic debris, colloids, etc. It is a thick substance between liquid and solid. It has a high content of toxic and harmful substances, especially the existence of pathogenic microorganisms, which can easily cause secondary pollution, endanger human health and damage the enviro...

Problems solved by technology

[0003] The cost of the traditional stack composting method is low, but it occupies a large area and easily causes secondary pollution. Using a simple box-type composting system is not conducive to temperature control and material moisture content control during the composting process, and it is easy to cause nitrogen and phosphorus nutrients.
