Abstract
The utility model discloses a heat-recovery fermentation cell which is characterized in that a waste heat recoverer is arranged between a blower and an exhaust blower which are communicated with the fermentation cell. The waste heat recoverer is respectively connected with a cold-hot blowing pipe and a cold-hot exhaust pipe. Because the utility model is additionally provided with a waste heat recoverer and formed of two loops, part cold air becomes warm air through obtaining heat energy in the waste heat recoverer rise in temperature of one loop and delivers to the refuse stack body which needs rise in temperature in fermentation prior period. In the other loop, the hot exhaust gas diverging from the refuse stack in the waste heat recoverer is transmitting the heat energy to the cold air and the becomes cold exhaust gas in temperature drop to be discharged. The defect existing in the existing technology that the lower temperature of the fermentation cell, influence of survival activities of microorganism and velocity and quality of compost is overcame. As possible as recovering the heat energy fermented from refuse to heat the fermentation cell blowing, and delivering warm air for refuse stack at the fermentation prior period. Consequently, the environment temperature adequate for microorganism survivals and activities is created, and the velocity of microbial degradation organic refuse is accelerated. The compost period of the living garbage is shortened, and the productivity of the fermentation cell is improved.
Description
Technical field:
The utility model belongs to domestic refuse aerobic composting fermentation apparatus technology, and specifically a kind of relating to reclaimed the recovery of heat fermentation cabin that rubbish fermentation heat energy is used to heat the fermentation cabin air-supply.
Background technology:
Common domestic refuse aerobic composting fermentation storehouse is equipped with fan, exhaust blower, blast tube, air-valve, air-supply trench, exhaust outlet, exhaust duct and blast cap at present.Outside air is delivered to domestic refuse in the fermentation cabin by blast tube and air-supply trench, to reach the purpose of oxygen supply or cooling after fan pressurization.Waste gas such as the carbonic acid gas that produces in the rubbish fermentation process, water vapor and ammonia then enter in the atmosphere by exhaust outlet, exhaust duct and blast cap after the exhaust blower suction.
As everyone knows, the process of domestic refuse fermented manure, come down to an organism that controlledly promotes in the microbiological deterioration rubbish, the Biochemical processes that organism is transformed to stable humus, microorganism can produce heat when the organism of degraded in the rubbish, along with gathering of heat, the temperature of junk-heap body rises gradually.The compost practice shows that 55 ℃～60 ℃ is best garbage compost temperature, and this moment, microorganism metabolism was active, the organism in the rubbish of degrading in a large number.The height of compost temperature directly influences the speed and the quality of survival activity and the compost of microorganism, and compost temperature is crossed when hanging down, and microbial activities slows down, even is in dormant state; When compost temperature is higher than 70 ℃,, thereby and may cause the volatilization loss of moisture and nitrogen to reduce fertilizer efficiency not only bad for microorganism growth.
At the consumer garbage compost earlier fermentation, the airy purpose is the needed oxygen of its growth and breeding to be provided and to get rid of the waste gas that produces in the rubbish fermentation process to microorganism; In the fermentation later stage, the airy purpose mainly is to reduce the temperature of rubbish, keeps the envrionment temperature that is fit to the microorganism survival activity.Existing aerobic fermentation chamber adopts the through type draft type, outdoor air directly arrives junk-heap body without temperature adjustment, at the heat of when microorganism provides oxygen, also having taken away microorganisms, caused the low temperature environment that is unfavorable for its growth and breeding, in the season and the zone of cold, this situation is particularly serious.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved recovery of heat fermentation cabin, its recyclable rubbish fermentation heat energy is used to heat the fermentation cabin air-supply, the junk-heap body that is in earlier fermentation is carried warm air, to create the envrionment temperature that is fit to the microorganism survival activity, accelerate the organic speed of microbiological deterioration, shorten the consumer garbage compost cycle, improve fermentation cabin productivity.
To achieve these goals, the technical solution of the utility model is: a kind of recovery of heat fermentation cabin, it mainly comprises fermentation cabin and the fan, the exhaust blower that match with fermentation cabin, be located at air-supply trench, exhaust outlet in the fermentation cabin, the hot and cold blast tube that is connected with fan, the hot and cold exhaust duct that is connected with exhaust blower, it is characterized in that: between the fan that is connected with fermentation cabin, exhaust blower waste heat recoverer is set, this waste heat recoverer is connected with hot and cold exhaust duct with hot and cold blast tube respectively.
The utility model is owing to set up waste heat recoverer, form two loops, on the energy recovery of rubbish fermentation, make an issue of, it is lower usually to put forth effort on the fermentation cabin temperature that overcomes the prior art existence, influence survival activity and the speed of compost and the defective of quality of microorganism, reclaim rubbish fermentation heat energy as far as possible and be used to heat the fermentation cabin air-supply, the junk-heap body that is in earlier fermentation is carried warm air, to create the envrionment temperature that is fit to the microorganism survival activity, accelerated the organic speed of microbiological deterioration, shorten the consumer garbage compost cycle, improved the productivity of fermentation cabin.
