Description

A kind of efficient changing food waste treatment unit
Technical field
The utility model is used to utilize the biological compost principle to changing food waste bottom reason, relates in particular to a kind of efficient, energy-conservation changing food waste treatment unit that integrates dehydration, decomposing and fermenting.
Background technology
In domestic waste classification, the sanitary waste that the resident is formed in the personal consumption process is referred to as changing food waste, comprises the perishability food garbage that perishability rubbish from cooking that family produces and restaurant, dining room, dining room etc. produce.Complicated component in the changing food waste is the mixture of multiple materials such as oil, water, pericarp, vegetables, rice and flour, fish, meat, bone and other waste, based on protein, starch, Mierocrystalline cellulose and animal tallow, and salinity, fat content height.Because contain rich nutrient substances in the changing food waste, if not treated direct discharging, can be putrid and deteriorated under the effect of temperature and bacterium, grow mosquitos and flies, not only environment is polluted, also can occupy a large amount of soils.If changing food waste and other domestic garbage mixing burning can be reduced its heat energy utilization greatly, lipid material wherein becomes the important factor that produces dioxin under the catalytic condition of heavy metal simultaneously; And landfill disposal can produce a large amount of biogas and percolate, and environment is caused secondary pollution.Therefore changing food waste is carried out special processing and effectively utilizes to have very significant meaning.
At present, domestic disposal to changing food waste also is in the starting stage, and common changing food waste treatment facility all is to utilize the microbiological deterioration principle to the changing food waste disaggregating treatment of fermenting, and it exists problems in actual motion is used:
Problem one: the changing food waste water ratio is big, and bacterial classification runs off, and processing cost increases.
The changing food waste water ratio is higher, directly drop into the changing food waste treatment facility and carry out compost treatment, just handle behind the perhaps just simple artificial draining, the percolate delivery ratio is more, and decomposing necessary microbial strains, rubbish fermentation will run off in a large number with the discharge of percolate, for guaranteeing treatment effect, the dosage of the necessary increasing bacterial classification of making use of momentum makes processing cost improve.Microbial strains action need certain temperature condition has, owing to just need heat to material again.And the water ratio height of material, specific heat is just big, and the material heating power is just big, makes energy consumption increase.
Problem two: increase pre-treating technology before the changing food waste treatment facility, floor space strengthens, and is difficult for centralized Control.
Independent mechanical dewatering equipment before entering the changing food waste treatment facility, material is set, though can solve the high problem of changing food waste treatment facility charging water ratio like this, the whole plant floor space is big, equipment disperses, centralized Control is not easy, and level of automation is low.And in transmission course, material can expose in air, can shed by frowziness, and environment is polluted.
The utility model provides a kind of efficient, energy-conservation changing food waste treatment unit that integrates dehydration, decomposing and fermenting.
Summary of the invention
The utility model aims to provide a kind of efficient, energy-conservation changing food waste treatment unit that integrates dehydration, decomposing and fermenting.
For addressing the above problem, the technical solution of the utility model is: with the integrated changing food waste treatment unit of dehydrating function and the organic integration of decomposing and fermenting function; A kind of solid-liquid separating equipment with the screw extrusion function, have hopper, device for transporting objects, material pressing device, squeezing reducing motor, rubbish is carried out the mechanical presses dehydration, the charging water ratio is dropped to about 65% by 90%, for further rubbish fermentation is provided by the condition that provides; Described hopper is arranged on the top of described device for transporting objects; Described material pressing device is installed on described device for transporting objects discharge end; A kind of garbage decomposition fermentation equipment with agitating auger, aerating apparatus, bacterial classification spray equipment, heating unit, reactor, stirring reducing motor, blower fan, discharge port, rubbish after the dehydration is carried out the microbial fermentation degraded, wherein the microbial fermentation degradation process of rubbish is carried out in reactor, described agitating auger is installed in described inside reactor, be used for the rubbish material in the reactor is stirred, the uniform mixing that impels bacterial classification and rubbish with air fully contact mixing; Described aerating apparatus is arranged on described reactor bottom, for the aerobic fermentation of rubbish provides required oxygen; Described bacterial classification spray equipment is arranged on described inside reactor top, and degrading for the quick fermentation of rubbish provides required bacterial classification; Described heating unit is installed in described reactor outer wall, and for the activity of microbial strains provides suitable temperature condition, better performance is active to make it; Described stirring reducing motor, blower fan are installed in the reactor outside; Described discharge port is arranged on an end of described reactor.
Preferably, described material pressing device is the screw press dehydration, and wherein the discharging water ratio can be regulated.
Preferably, described agitating auger is the twin-shaft screw-type agitator, form by stir shaft and belt spiral, wherein the rotating speed of twin shaft, turn to and rotational frequency all can regulate separately, be provided with.
Preferably, described aerating apparatus is made up of well heater, reactor inlet system and axle head inlet system, can heat air intake, and avoiding into, cold wind can reduce temperature of charge, help the quick fermentation degraded of material, wherein aeration air quantity, aeration frequency all can be regulated.
Preferably, described heating unit is made up of heating piece and attemperator, is whole outer wall even heating.
Compare existing installation, advantage of the present utility model has: because the changing food waste complicated component adopts the dehydration of screw press formula can better guarantee the water ratio of discharging; The twin-shaft screw-type agitator is better to the material mixing effect, make the material not only can be in reactor inside diameter to rolling, can also be vertically at the reactor internal recycle, microbial strains and air can be mixed more fully with material, stir simultaneously and fully also can avoid because being heated of causing of rubbish material self mobile bad is inhomogeneous the too high phenomenon of local heating's temperature; Reactor monolith outer wall even heating disperses hot spot, also can avoid because being heated of causing of rubbish material self mobile bad is inhomogeneous, and the too high phenomenon of local heating's temperature improves heating efficiency, effective save energy; With the organic integration of all functions equipment is one, and floor space is little, is convenient to operation control; Totally-enclosed design, the omnidistance nothing of processed rubbish material is exposed, environmentally safe.
