Temperature control system and temperature control method for microbial decomposition process of organic matters

Abstract

The invention provides a temperature control system and a temperature control method for the microbial decomposition process of organic matters, and aims to provide a temperature control system and a temperature control method for the microbial decomposition process of organic matters. According to the technical scheme of the invention, the fact that the microbial activities of different microflora in different temperature conditions are diversified is fully utilized. Therefore, the decomposition treatment effect of organic matters is improved. The temperature control system comprises a material temperature sensor, an oxygen supply temperature sensor, an ambient temperature sensor, an exhaust gas temperature sensor, a material temperature signal processor corresponding to each temperature sensor, an oxygen supply temperature signal processor, an ambient temperature signal processor, an exhaust gas temperature signal processor, a material heater, an oxygen supply heater, an exhaust device, a dust-removing heater and a stirring device. The signal line of each temperature signal processor is respectively connected with an input module. An acquired data signal is analyzed and processed by a programmable logic controller (PLC), and then the temperature in a decomposition chamber is adjusted by a temperature adjusting assembly under the control of an output module.

Description

Technical field [0001] The present invention relates to the technical field of organic matter decomposition, in particular, to a temperature control system and a control method for a microbial decomposition process of organic matter. Background technique [0002] Domestic waste is a global social problem that pollutes the urban and rural environment, affects people's lives, and disturbs urban development. At present, my country produces 66 million tons of food waste every year, and the annual growth rate is 10%. The annual processing cost is more than 50 billion. Food waste disposal capacity is seriously insufficient, and the current domestic harmless disposal rate is only 10%. Poor handling of food waste will pollute water, soil and atmosphere. The return of kitchen waste from Nuo food to the table will cause damage to the health of residents. At the source of kitchen waste, microbiological decomposition is used to reduce the volume and volume, thereby reducing the impact on...

Problems solved by technology

The disadvantage of this method is: it will produce sewage discharge, smelly

The disadvantage of this method is that it cannot fully reflect the requirements of different temperature regions for the growth, reproduction, and material decomposition state of microorganisms in the process of microbial decomposition, resulting in insufficient decomposition of organic matter, low decomposition efficiency, and it is difficult to achieve no sewage discharge. easy to smell

[0007] In the prior art equipment that uses microorganisms to decompose organic matter, the temperature sensor is mainly installed in the upper cavity of the decomposition chamber and does not contact the material, so it cannot accurately reflect the temperature state of the material; Control, unable to meet the dynamic balance requirements for heat energy in the process of microbial decomposition

Therefore, the existing equipment that uses microorganisms to decompose organic matter cannot increase the speed and degree of microbial decomposition, and it is easy to reduce the activity of microbial decomposition, reduce the amount of decomposition, and easily generate odor
