Abstract
The utility model relates to equipment for sterilizing solid particles. The equipment consists of a circulating fluidized bed 1, a gas supplying device 6 and a sterilizing gas source 9, wherein the sterilizing gas source 9 is arranged at one side of the fluidized bed and supplies sterilizing gas to the circulating fluidized bed 1; the sterilizing gas is ozone or related gas; in order to guarantee the needs of solid particle sterilization, a fluidization chamber of the circulating fluidized bed 1 serves as a workspace through which the particles are in contact with the ozone and are sterilized, and the particles are in full contact with the sterilizing gas in the space so as to be sterilized; and a separating machine 10 is arranged at the other side of the circulating fluidized bed 1 and is used for separating gases and a small amount of solid particles, which flow out of the fluidized bed, and a pump 11 is arranged at one side of the separating machine and is used for pumping back the sterilizing gas so as to recycle the sterilizing gas. According to the equipment, the particles can be enabled not to be brought out of the fluidized bed by circular-flowing gas flow, so that the condition that the particles can be sterilized completely is guaranteed; a system is a closed circulating space; and the ozone or sterilizing gas and the particles flow circularly and are in full contact in the circulating fluidized bed 1, so that the particles are sterilized.
Description
Technical field
The art of this patent belongs to biomedicine field, relates in particular to the solid particle sterilizing installation of biological medicine.
Background technology
Many process needs carry out sterilization treatment to solid particle.The past sterilization process mainly adopts heating or chemical method, and heating means make bacterial enzyme deactivation in heating process.This technology has its limitation, and namely active component has temperature-sensitive effect or relevant effective ingredient thermo-labile to heat in the raw material, and heating will cause the biomaterial active ingredient loss, even active component wrecks.Chemical method forms easily and pollutes owing to need solvent and add relevant reagent, and this pollution must avoided sometimes.
Take place for fear of above phenomenon, the art of this patent adopts non-heat sterilization control technology, makes the active deactivation of raw material bacterial enzyme, and other active component can not be affected because of heat effect in this process simultaneously.
Nonthermal process is controlled the activity of bacterial enzyme under the process conditions that do not heat, therefore, this method can make the biomaterial active component be kept to greatest extent, belongs to a treatment process preferably.
But, non-heat sterilization is handled and is related to liquid mostly, there are many problems in enzyme denaturing processing to solid particle, the solid particle particle is little, the ion surface sterilization process is difficult to carry out, and generally adopts radiation treatment only, because radiation treatment can be brought some unknown biological effects, therefore, many occasions also can avoid adopting the radiation treatment biological product.Thus, the non-hot enzyme denaturing of solid particle is handled and is difficult to that always good method is arranged.
Sterilizing gas has fluid bed solid particle sterilizing methods to the granule sterilizing methods at present, and still, the limitation of this technology also is obvious; the size of grain diameter is restricted; particle diameter is too little, and granule can be overflowed with gas and be discharged fluid bed in the fluid bed, does not reach the purpose that granule is sterilized fully.This patent has been invented the sterilizing installation that is fit to all kinds of grain diameter situations in order to overcome the deficiency of conventional art.
Summary of the invention
This utility model purpose for implement the sterilization to solid particle, particularly grain diameter less than 100 microns for this reason, adopted sterilizing gas and circulating fluidized bed system that granule is implemented sterilization.Simultaneously, this device can be realized the serialization operation.
In order to realize above purpose, this utility model adopts following technical scheme: the difference of it and existing technology is: system is made up of recirculating fluidized bed, side at fluid bed is provided with sterilization source of the gas feed system, the outlet of sterilization source of the gas links to each other with the feeder entrance, and the feeder outlet links to each other with recirculating fluidized bed air-flow lower inlet.Sterilizing gases used is ozone or associated gas, in order to guarantee granule sterilization needs, and the work space that recirculating fluidized bed fluidising chamber contacts and sterilizes with sterilizing gas as granule, granule fully contacts sterilization in this space with sterilizing gas.
Operation principle: granule enters fluidising chamber by the Circulating Fluidized Bed entrance, sterilizing gas is entered by the recirculating fluidized bed lower inlet, particle suspending also contacts with sterilizing gas, recirculating fluidized bed is owing to be provided with interior or external circulating device, granule can not taken out of fluidising chamber by air-flow in fluidising chamber, and sterilization back granule is discharged by the Circulating Fluidized Bed outlet.
Another improvement of this utility model is: the recirculating fluidized bed opposite side is provided with seperator, and seperator is used for flowing out separating of fluidized bed gas and solid particle, and seperator one side is provided with pump, and this pump is returned sterilizing gas and recycle.
The beneficial effects of the utility model are: the sterilization granule is sterilized in sterilizing gas, and simultaneously, owing to adopted recirculating fluidized bed as bactericidal unit, granule can not overflowed with air-flow in sterilization, and this bactericidal unit can be effectively applied to the sterilization of granule.
Description of drawings:
Fig. 1 is this utility model embodiment.
The specific embodiment:
For convenience of explanation, below adopt the mode of accompanying drawing to illustrate:
Specific embodiment as shown in Figure 1, a kind of bactericidal unit system, this system is gases used to be ozone or relevant sterilizing gas, device is made up of recirculating fluidized bed 1, sterilization source of the gas 9, feeder 6, seperator 10, pump 11.Sterilization source of the gas 9 is provided with sterilizing gas, sterilization source of the gas 9 links to each other with feeder entrance 7 by pipeline, feeder outlet 8 links to each other with recirculating fluidized bed air-flow lower inlet 2 by pipeline, sterilizing gas enters recirculating fluidized bed 1 by entrance, material then enters fluid bed from Circulating Fluidized Bed entrance 4, because recirculating fluidized bed 1 can make granule fluidisation in bed also can constantly circulate in fluid bed, ozone or other sterilizing gas will fully contact with material and to the granule sterilization, granule sterilization back is discharged by Circulating Fluidized Bed outlet 5.3 of recirculating fluidized bed air-flow upper outlets link to each other with seperator 10 by pipeline, gas is discharged by seperator 10 discharge gates with a small amount of material particles material, seperator 10 outlets link to each other with exhaust pump 11 by pipeline, the outlet of exhaust pump 11 is connected to the entrance 7 of feeder by pipeline, makes gas circulation use.
During use, sterilization source of the gas 9 provides sterilizing gas by pipeline for feeder 6, and this gas is ozone or other sterilizing gas as formaldehyde, L oxirane, oxirane etc.Feeder 6 provides the granule sterilizing gas by pipeline for recirculating fluidized bed 1.Granule enters a body by Circulating Fluidized Bed entrance 4, and formation particle bed, the granule granule bed surface of in the flowing of sterilizing gas, can not overflowing, in the recirculating fluidized bed 1 or the outer circulation gas-solid separating device this granule is sent back to constantly circulation in the grain bed by closed circuit.Sterilizing gas enters seperator 10 by the particle bed by recirculating fluidized bed air-flow upper outlet 3, and on a small quantity with being come out by seperator 10 after the gas effusion particle separation, gas is then returned the source of the gas place by pump 11 and recycled.
