HTHP medical treatment solid waste is disposal plant on the spot
Technical field
The present invention relates to a kind of Solid Waste Treatment device, is a kind of medical solid waste treating apparatus of HTHP disposal on the spot specifically.
Background technology
Contain the multiple main pathogens that infects of causing in the clinical waste,, have space infection, acute infection, cross infection and characteristic such as the infection of hiding like bacterium, virus, fungi, actinomyces etc., clinical waste enormous amount, of a great variety, harmfulness is bigger.The existing main method of disposal construction of the medical solid waste center of centrally disposing of China centrally disposes, and the technology of employing mainly contains: burning method, autoclaving (or wet heating), pyrolysismethod etc.
What use amount was maximum at present is burning method; The burning method technology maturation; Can dispose the pollutant of difficult degradation, but can produce hazardous wastes such as violent in toxicity, residue and flying dust such as dioxin when burning, the suction that needs on the actual engineering to carry out toxicant with a large amount of active carbons is exhaled; And the existing method of disposal of the active carbon that contains a large amount of toxic ingredients is to deliver to landfill yard to carry out landfill, forms the transfer of pollutant.
It also is to be applied in to centrally dispose on the engineering that pyrolysismethod is disposed clinical waste; This method is under the condition of high temperature anoxic; The clinical waste pyrolysis is become high-temperature gas and lime-ash; Pyrolysis is supplied with air in certain amount in the stove domestic demand and is formed bottom and burn, and burns pyrolytic layer that the heat that produces reaches the upper strata and drying layer etc., and because a certain amount of dioxin of the same generation of the existence of burning.
Autoclaving is also claimed wet heating, is to utilize overheated steam to kill the wherein method of pathogenic microorganisms, and its method is simple, disposes the back sterilization thoroughly, and the domestic how tame medical solid waste of this method construction that used centrally disposes engineering now.
Domesticly built many medical solid waste and centrally disposed the center; Construction centrally disposes the center location difficulty, land occupation is many, the construction period is long, and equipment operating cost is high after the engineering construction, technology is immature, equipment failure rate is high, all can produce secondary pollution when moving.
In addition, existing method also has plasma method, microwave method, radiation treatment method and landfill disposal etc., and all there are all kinds of weak points in these methods, fails to realize the large-scale promotion application so far.
Summary of the invention
To centrally dispose medical solid waste disposal center construction difficulty, collection difficulty, transportation difficulty at present in order overcoming, to manage difficulty and cost height; Have various pollutions, safety, the incomplete hidden danger of disposal, can't satisfy the deficiencies such as requirement at hospital's site disposal, the HTHP that the present invention proposes a kind of medical solid waste is disposal plant on the spot; This device has realized that not only the hospital of clinical waste disposes on the spot; And in disposal process, have no secondary pollution, dispose fully, safe in utilization.
The technical scheme that the present invention adopts is: a kind of HTHP medical treatment solid waste is disposal plant on the spot; Comprise the high-temperature high-pressure reaction kettle, steam generating device and the complete machine power supply that all are connected in system's switch board; Steam generating device is communicated with high-temperature high-pressure reaction kettle; Its technical characterstic is to be connected with pumped vacuum systems and emission control system on the said high-temperature high-pressure reaction kettle, and the equal connected system switch board of pumped vacuum systems and emission control system is realized vacuumizing and exhaust gas purification in the high-temperature high-pressure reaction kettle.
Said high-temperature high-pressure reaction kettle is the horizontal reacting still, and high-temperature high-pressure reaction kettle one side is provided with feeding gate, and feeding gate is provided with and opens the door and locking device.
Said high-temperature high-pressure reaction kettle inner bottom part level is provided with Car Track, slides on the Car Track to be provided with the charging car of placing medical solid waste.
Said high-temperature high-pressure reaction kettle top is provided with temperature detection data acquisition mouth and pressure detecting data acquisition mouth.
Said high-temperature high-pressure reaction kettle bottom is provided with venting.
Said pumped vacuum systems comprises and vacuumizes control valve and vavuum pump, vacuumizes control valve one end and connects high-temperature high-pressure reaction kettle, vacuumizes the control valve other end and connects vavuum pump; Said emission-control equipment comprises gas exhaust-control valve, gas cleaning plant and air-introduced machine; Gas exhaust-control valve one end connects high-temperature high-pressure reaction kettle; The gas exhaust-control valve other end connects air-introduced machine through gas cleaning plant, and said vavuum pump is connected to gas cleaning plant.
Be provided with auxiliary heating element in the said high-temperature high-pressure reaction kettle.
Said steam raising plant is communicated with high-temperature high-pressure reaction kettle through steam supply valve, steam control valve.
Said vacuumize to be provided with between control valve and the vavuum pump vacuumize check valve, be provided with the gas discharge one-way valve between said gas exhaust-control valve and the gas cleaning plant.
The medical solid waste that to dispose through charging car is written in the high-temperature high-pressure reaction kettle and with its sealing along Car Track; At first start pumped vacuum systems, reach certain vacuum in the question response still after, steam generator feeds high pressure, high temperature vapor in the agitated reactor; Agitated reactor gets into the sterilizing works state; Accomplish the sterilization of medical solid waste behind the effect certain hour, open subsequently and after the gas exhaust-control valve makes agitated reactor reach normal pressure charging car is taken out, the medical solid waste after the sterilization is exported with charging car; It is got into breaker unmake, the back of unmaking is sent into house refuse as Ordinary solid waste and is disposed the center or deliver to the landfill yard landfill.
After adopting above technical scheme, the beneficial effect that the present invention reaches is: it is convenient that charging car is collected medical solid waste, and charging car is sent into medical solid waste in the high-temperature high-pressure reaction kettle along Car Track, and is simple to operate; Venting occurs opening automatically when unusual in the high-temperature high-pressure reaction kettle internal pressure, implements pressure protect, and is safe in utilization; Gas cleaning plant purifies the gas that vacuumizes with exhaust, avoids secondary pollution; High-temperature high-pressure reaction kettle is acted on the on-the-spot medical solid waste of hospital or medical center; Realized the site disposal of medical solid waste, overcome existing medical solid waste and focused on potential safety hazard and the management inconvenience that the collection difficulty, the cost of transportation that bring are high, transportation is run off to bring; HTHP is the biolytic interior tissue of protein coagulating to action of microorganisms such as bacterium, moulds, and makes it very fast dead, and the killing action principle is simple, thorough, and on-the-spot service requirement is not high, is easy to engineering and promotes; This physics method is disposed, and does not produce poisonous and harmful substances such as sour gas, heavy metal, dioxin, flying dust, and it is little to dispose on-the-spot floor space, simple to operate, safety, and installation cost is low, is easy to promote.
