Description

Kitchen waste fermentation bin drying and dehumidifying device adopting air energy heat pump

Technical Field

The utility model belongs to the environmental protection field relates to an adopt kitchen garbage fermentation storehouse stoving dehydrating unit of air energy heat pump.

Background

With the continuous improvement of the living standard of people, the discharge amount of kitchen waste is increased day by day. A large amount of kitchen waste brings serious pollution and huge waste, and brings great trouble to environmental protection. Only by further resource utilization of the kitchen waste containing rich biomass, the environmental protection can be facilitated, the utilization degree of human beings on renewable resources can be increased, and the development direction of sustainable development and circular economy is met

The current treatment technology of kitchen waste mainly comprises the following steps: landfill treatment, incineration treatment, feed treatment, anaerobic fermentation treatment, aerobic composting treatment, aerobic microorganism treatment and the like.

The aerobic microorganism treatment technology is a more common and mature treatment technology. But not only feed treatment or aerobic composting treatment. In the prior art, the whole process needs dehydration, dehumidification or drying to achieve the maximum decrement of the water content.

Most of the existing methods for dewatering and reducing the quantity of kitchen waste are in the process of kitchen waste fermentation: the dewatering is reduced by draining water or heating to achieve thermal gasification ventilation. Generally, the water content of the kitchen waste is reduced to a water content close to that of the fermentation of the strains (for example, the water content of a B-type microbial agent in a microecological microbial agent of Shanghai dry-bound Biotech limited company is 50% -60% by fermentation) through pretreatment, such as crushing and extrusion treatment. And then the kitchen waste is sent into a fermentation bin of the kitchen treatment equipment for fermentation, the fermentation bin is provided with a bin body heating source for heating the kitchen waste to the fermentation temperature required by the strains, and the kitchen waste is fermented under the conditions of certain moisture content and temperature. There are generally two ways of handling the water produced during fermentation: the first is direct drainage. Directly discharging the water generated in the fermentation process, pumping the water to oil-water separation equipment, and then performing water treatment. The second is thermal gasification. Through the air in heating fermentation storehouse, make the air after relative humidity reaches the concentration under the environment of high temperature, open the breather valve, outside the fermentation storehouse air discharge storehouse with high humidity, gaseous emission processing is carried out to the rethread deodorization system.

However, the two existing dehumidification technologies have the disadvantages that:

1. the secondary pollution can be produced to the drainage mode, even water treatment such as rethread oil-water separation, the drainage decrement still is limited, reaches the effect of true decrement, still will cooperate the second mode under most circumstances, and the technical shortcoming is: secondary pollution, long treatment period, various related equipment, complex treatment procedures, high equipment cost, high post-operation cost and the like.

2. The method is a thermal gasification process for directly heating materials or air in a fermentation bin, discharging moisture out of the fermentation bin through air humidity, and treating the discharged gas through deodorization equipment, such as UV ultraviolet deodorization, plasma deodorization, spray tower deodorization and the like. The technical defects are as follows: equipment, processing cost and energy consumption are increased; moreover, the gas after the deodorization treatment affects the surrounding environment, and is liable to cause complaints from surrounding residents.

The refrigerant after releasing heat is output from the water-fluorine condenser 2, passes through the liquid storage tank 6 (the liquid storage tank plays a role of supplementing the refrigerant) and the filter 18, is sent to the electronic expansion valve 3, and is decompressed into low-temperature and low-pressure gas under the action of the brake flow of the electronic expansion valve 3. The low-temperature and low-pressure gas enters the wind-fluorine evaporator 17, the heat of the wind-fluorine evaporator 17 is absorbed to reduce the temperature of the wind-fluorine evaporator 17, and at the moment, the wind-fluorine evaporator 17 rapidly absorbs the heat into the air through a fan (the wind of the fan is changed into cold wind for refrigeration after passing through the wind-fluorine evaporator 17). The low-pressure refrigerant after the refrigerant absorbs heat through the wind-fluorine evaporator 17 passes through the low-pressure valve 10 (low-pressure protection function) and the low-pressure meter 9 (low-pressure monitoring function), then is sent to the other group of input ends of the four-way valve 5, is output from the other group of input ends, passes through the gas-liquid separator 7, and flows back to the air energy heat pump compressor 16 to repeat a new cycle of compression. The heat in the air is continuously absorbed by the wind-fluorine evaporator 17 and then is sent to the water-fluorine condenser 2 to provide heat for the scene.
