Sludge drying incineration energy-saving control device and method

Abstract

The invention relates to a sludge drying incineration energy-saving control device and method. The device comprises a wet sludge storage bin, a wet sludge conveying pump, a pipeline type sludge moisture content microwave transmitter, a sludge drying machine, a dry sludge buffering bin, a stock bin type sludge moisture content microwave transmitter, a dry sludge conveying pump and a sludge incinerator. The pipeline type sludge moisture content microwave transmitter is arranged between the wet sludge conveying pump and the sludge drying machine; the stock bin type sludge moisture content microwave transmitter is mounted on the dry sludge surge bin; the sludge drying machine is connected with a drying machine heat source; the sludge incinerator is connected with a fuel source through a combustion-supporting fuel pipeline. The amount of wet sludge entering the sludge dryer can be controlled in real time, the introduction amount of a heating medium is controlled in real time, the use amount of the heating medium is saved, and the operation efficiency of the sludge dryer is improved; and the water content of the dried sludge can be monitored in real time, the amount of the dried sludge entering the sludge incinerator is controlled, the use amount of the combustion-supporting fuel is adjusted in real time, the use amount of the combustion-supporting fuel is saved, and the operation efficiency of the sludge incinerator is improved.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment and disposal, and in particular relates to an energy-saving control device and method for sludge drying and incineration. Background technique [0002] The output of urban sludge in my country is increasing, and proper disposal of sludge has become an urgent task. Sludge drying and incineration technology can process a large amount of sludge in a short time, and can recover the heat of incineration. It is an efficient technical means of sludge disposal at present. The "Technical Guidelines for Sludge Treatment and Disposal in Urban Sewage Treatment Plants" points out that when the sludge is incinerated alone, drying and incineration should be used in combination to improve the thermal energy utilization efficiency of the sludge. In recent years, with the continuous optimization of drying technology and incineration technology and the maturity of the process, great progress has been made ...

AI Technical Summary

Problems solved by technology

At present, there is no device and method to control the amount of heat medium in the dryer and the amount of combustion-supporting fuel in the incinerator through real-time measurement of the moisture content of the sludge.
