Problems solved by technology

[0004] Existing sludge dryers only simply dry the sludge. There is no certain detection of the drying effect, no control over the moisture content, and the moisture content of the final dried sludge is also unstable. , which is not conducive to the realization of later reuse; in addition, since the dried sludge is generally heated by high temperature to remove water, the waste heat carried by the dried sludge has not been utilized, wasting energy

Abstract

The invention discloses a sludge moisture content control device. The sludge moisture content control device comprises a drying device for heating and dehydrating sludge and further comprises a detection device which is arranged behind the drying device and is used for carrying out online detection on the sludge moisture content; a high-temperature dry air inlet and a low-temperature non-dry air outlet are arranged at one side of the drying device, and a low-temperature non-dry sludge inlet, a high-temperature dry sludge outlet and a sludge recycling inlet are arranged at the other side of thedrying device; the detection device comprises a detection inlet, a qualified sludge outlet and an unqualified sludge outlet, which are communicated with the high-temperature dry sludge outlet; and the unqualified sludge outlet is communicated with the sludge recycling inlet of the drying device. Compared with the prior art, the sludge moisture content control device provided by the invention hasthe advantages of optimal heating and drying effect, high efficiency, stable moisture content of the treated sludge, great single-time treatment amount of the sludge, energy source saving, economic efficiency and environment protection.

Description

Technical field [0001] The invention relates to the technical field of sludge drying devices, in particular to a sludge moisture content control device and a moisture content adjustment method. Background technique [0002] Sludge is a solid precipitation material produced by water and sewage treatment processes. Its main characteristics are: high water content (can be as high as 99% or more), high organic content, easy to rot and smell, and the particles are finer, the specific gravity is small, and it is in a colloidal liquid state. The main sources of sludge are: domestic sewage sludge, industrial wastewater sludge and water supply sludge. The disposal and treatment of all kinds of sludge has become a chronic disease hindering urban development and urban sanitation. [0003] With the strengthening of national energy conservation and emission reduction efforts, the improvement of national awareness of environmental protection, and the increasing production of urban sludge, the ...
