Kitchen waste treatment device and method with improved dry-type anaerobic fermentation effect

Abstract

The invention discloses a kitchen waste treatment device and method with an improved dry-type anaerobic fermentation effect. The device comprises a fermentation tank, a stirring assembly, a sensing assembly, a control assembly, a heating assembly and an adsorption assembly, wherein the adsorption assembly comprises an electromagnetic coil arranged on the outer side face of the fermentation tank, and the heating assembly comprises a heating sheet which is arranged on the outer side face of the fermentation tank and is adjacent to the electromagnetic coil; the sensing assembly comprises a first temperature sensor and a second temperature sensor, the second temperature sensor is used for sensing an internal temperature of the fermentation tank, and the first temperature sensor is used for sensing a temperature of the heating sheet; and the control assembly can be used for controlling independent make and break of the electromagnetic coil and can also be used for controlling simultaneous make and break of the electromagnetic coil and the heating sheet according to a sensed result of the sensing assembly. According to the device and the method, a stable-temperature uniform-heated fermentation environment can be provided for anaerobic bacteria in the fermentation tank, the problem of dead corners for stirring is effectively solved, and the efficiency and quality of decomposition of the anaerobic bacteria to kitchen wastes are improved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment in the environmental protection industry, and particularly relates to a kitchen waste treatment device that improves the effect of dry anaerobic fermentation by adding a new type of recyclable medium, and uses the kitchen waste treatment device to process food waste. The method of processing. Background technique [0002] Anaerobic digestion technology is an environmentally friendly and comprehensive resource utilization process. It has been used in my country for nearly 20 years, and the related technology is relatively mature. From the principle point of view, this technology mainly uses anaerobic microorganisms to decompose organic matter. It can effectively treat food waste and promote the conversion of biomass energy into clean energy, which meets people's environmental protection requirements for food waste treatment. The earliest application of anaerobic digestion technology...

Problems solved by technology

[0005] (1) The structural design of many fermentation tanks and agitators is still based on experience, and there are many unreasonable phenomena in the design, such as poor applicability, short life, poor durability, and irregular design of fermentation tanks, which may easily cause fermentation effects Unsatisfactory and material waste and loss;

[0006] (2) In the current large-scale anaerobic tank, due to the unreasonable installation position of the agitator and the non-standard setting of the agitator installation parameters, the agitation effect is poor, and it is easy to cause a dead bed, resulting in easy acidification and expansion of the sludge, and it is difficult for anaerobic bacteria to grow rapidly. Pollution holding and decontamination effect is not ideal, biogas is scarce

The structural design of the fermenter and agitator is crucial to the smooth progress of the anaerobic fermentation process, but there are many unreasonable phenomena at present, the labor cost consumed in the design and manufacturing process is very huge, the design is not standardized, and it is easy to cause waste and loss of materials. Therefore, it is very important to scientifically, reliably and economically design the structure of the fermenter and agitator
