Description
Technical field
The utility model relates to technical field of waste treatment, and in particular to a kind of medical waste vacuum anaerobic pyrolysis processing system
System.
Background technique
Medical waste is the solid waste of the generations such as medical institutions, disease research mechanism, it is main include operation excision object,
Surgical dressing, infusion apparatus, syringe, blood bag, the treatment waste with body fluid, blood, phlegm, secretion, the vomitus of sufferer are examined
It is useless after mobile population belongings discarding in the discarded sample of section, pathology department, laboratory animal corpse and medical institutions
Gurry, etc..Medical waste can be divided into combustible component (organic matter) and non-combustible component, and combustible component includes plastic products, rubber
Glue product, biomass product, synthetic fibers, drug, animals and plants corpse etc., non-combustible component include glass, ceramics, metal etc..
Medical waste often contains a large amount of bacterium, virus etc., has very strong infectiousness, if do not strengthened management, arbitrarily abandoning, easily
Atmosphere, water source, soil and animals and plants are polluted, transmission is caused, seriously endangers the health of the people.
Currently, treatment of!medical waste method mainly includes that voluntarily burning disposal and environmental sanitation or environmental protection administration's concentration are burnt for hospital
The modes such as burning processing burn equipment incinerator used, and most of structure is simple, be simply equipped, waste incineration is insufficient, burn
The total number of bacteria in residue and colititer have over-standard phenomenon afterwards, and have checked pathogen, do not meet wanting for harmless treatment
It asks.Meanwhile the smell and flue dust generated in Refuse Incineration Process is not handled substantially, is polluted surrounding enviroment, is caused secondary
Pollution brings very big harm to nearby residents life.
Utility model content
In order to solve the above technical problems, the utility model provides, a kind of operating cost is low, medical rubbish of non-pollutant discharge
Rubbish vacuum anaerobic pyrolysis treatment systems.
The technical solution of the utility model is as follows：
A kind of medical waste vacuum anaerobic pyrolysis treatment systems, including sequentially connected pulverizer, charger, vacuum and low temperature
Drying oven, vacuum thermal cracking reaction kettle, cooling unit, cyclone dust collectors, bag filter, air accumulator, combustion furnace, air blower,
Chimney, the cyclone dust collectors, bag filter, vacuum thermal cracking reaction kettle are connect and will be consolidated by conveyer with centrifugal blower
Body residue is conveyed into centrifugal blower, so that lime-ash and heavy metal be separated, the vacuum dehydrating at lower temperature furnace is also logical with combustion furnace
Piping connection conveys the exhaust gas of generation into burning in combustion furnace, the flammable synthesis gas generated in vacuum thermal cracking reaction kettle
Cyclone dust collectors are sequentially entered after cooling unit is cooling and bag filter is dusted, subsequently into storing up in air accumulator
It deposits, the gas in air accumulator, which enters in combustion furnace, to burn and to the heat supply of heat scission reaction kettle.
Preferably, the charger is metering hydraulic charger, and work efficiency is high, does not allow easy break-down, metering quasi-
Really.
Preferably, the cooling unit uses water-cooling pattern, at low cost, easy installation, good cooling results.
Preferably, the pulverizer is pair roller pulverizer, is particularly suitable for medical waste.
Medical waste is handled using this system, rubbish needs not move through screening, first passes around pulverizer and be ground into fractionlet, adopt
Enter vacuum dehydrating at lower temperature furnace with intermittent batch, the dry solid after drying passes through closed conduit and is sent into vacuum thermal cracking reaction kettle
Middle pyrolysis processing, generates flammable synthesis gas, and synthesis gas a part is admitted to combustion furnace burning and heating gas to vacuum thermal cracking
Reaction kettle heat supply, remainder can use other purposes, generate in pyrolytic process without exhaust gas, waste water.In vacuum thermal cracking reaction kettle
Middle medical waste is pyrolyzed as gas (CO, CH4、H2、CO2Deng) and solid residue (carbon black, clinker, heavy metal).
The utility model has the beneficial effects that：Clinical waste is pyrolyzed by this system under anoxic or anaerobic hot conditions, is produced
Pyrolysis gas, is then passed through in combustion chamber and burns, clinical waste is finally transformed into synthesis gas and ash by raw imflammable gas
Slag, heavy metal etc. mostly remain that there are in lime-ash.This system high degree of automation, required operator are few；System operation
It is at low cost, service life of equipment is long, non-pollutant discharge.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
A kind of medical waste vacuum anaerobic pyrolysis treatment systems as shown in Figure 1, mainly by sequentially connected pulverizer 1,
Charger 2, vacuum dehydrating at lower temperature furnace 3, vacuum thermal cracking reaction kettle 4, cooling unit 5, cyclone dust collectors 6, bag filter 7,
Air accumulator 8, combustion furnace 9, air blower 10, chimney 11 and centrifugal blower 12 form.Cyclone dust collectors 6, bag filter 7, vacuum
Heat scission reaction kettle 4 is connect by conveyer with centrifugal blower 12 and conveys solid residue into centrifugal blower 12, thus by grey
Slag and heavy metal separate, and vacuum dehydrating at lower temperature furnace 3 is also connect by pipeline with combustion furnace 9 and conveys the exhaust gas of generation into burning
It burns in furnace 9, the flammable synthesis gas generated in vacuum thermal cracking reaction kettle 4 sequentially enters rotation after cooling unit 5 is cooling
Wind deduster 6 and bag filter 7 are dusted, and subsequently into storing in air accumulator 8, the gas in air accumulator 8 enters burning
It burns in furnace 9 and to 4 heat supply of heat scission reaction kettle.
Preferably, charger 2 is metering hydraulic charger, and cooling unit 5 uses water-cooling pattern, and pulverizer 1 is pair roller type
Pulverizer.
The course of work of this system is：
Vacuum dehydrating at lower temperature furnace is entered by the intermittent batch of charger after being crushed in medical waste conveyer pulverizer
Middle processing, carries out preliminarily dried in furnace, and the exhaust gas generated in drying process enters the burned processing of combustion furnace by pipeline, does
Dry solid after dry is delivered into vacuum thermal cracking reaction kettle by closed conduit to be handled, and pyrolysis generates flammable synthesis gas,
The solid that heavy metal etc. cannot be pyrolyzed retains that there are in residue.Residue be delivered into from vacuum thermal cracking reaction kettle from
Heart blower, flammable synthesis gas come out from vacuum thermal cracking reaction kettle and are cooled down through cooling unit, removed subsequently into whirlwind
The rough dedusting of dirt device, the thin dedusting of bag filter, enter back into air accumulator storage, and synthesis gas a part in air accumulator is admitted to burning
Furnace burning can give the heat supply of vacuum thermal cracking reaction kettle, also can be used as other energy sources.In cyclone dust collectors, bag filter
Dedusting collect residue be also passed into centrifugal blower, centrifugal blower lime-ash and heavy metal are sorted out so that lime-ash and
Heavy metal, which can separate, to fill or carries out further to utilize processing.
Clinical waste is pyrolyzed by this system under anoxic or anaerobic hot conditions, generates imflammable gas, then will pyrolysis
Gas, which is passed through in combustion chamber, to burn, and clinical waste is finally transformed into synthesis gas and lime-ash, and heavy metal etc. mostly remains
There are in lime-ash.This system high degree of automation, required operator are few；System operation cost is low, service life of equipment is long, nothing
Pollutant emission.
