Description
Technical field:
The invention belongs to low temperature sterilization device field, be specifically related to a kind of multi-zone separately controlled plasma sterilizer.
Background technology
Plasma sterilizer is present state-of-the-art low temperature sterilization technology, have safety, environmental protection, plurality of advantages such as energy-conservation, efficient, can supply the defective of conventional high-temperature steriliser fully, be the substitute products of toxic, inefficient steriliser such as oxirane, formaldehyde, glutaraldehyde.But compare with these products, the capacity of plasma sterilizer is little a lot, cost is high a lot, can't satisfy large-scale application demand.
The vacuum system of plasma sterilizer, temperature control system and loading system are subjected to the influence of capacity all apparent in view, and these also all are the unusual parts of core in the product.Consider that with combined factors such as main parts size and product configured in one piece and performance indications the total capacity of single inner room should not surpass 400L; If the space availability ratio height, practical capacity can be a little more than 300L.The demand of general curative and scientific research purposes can be satisfied in such space, but just seems more limited for industrial use and large-scale medical treatment and scientific research purposes, and its cost, Capacity Ratio are unsatisfactory.
Through demonstration, the problems referred to above can't increase with increase-volume conventional method such as joins and thoroughly solves, and only can alleviate slightly, and the cost of paying is the significantly reduction of significantly increasing of cost and efficient.
1) U.S.'s esbablished corporation is the senior statesman of plasma sterilization industry, and its product is able to extensive popularization at medical treatment, the scientific research field in the whole world, but seldom uses at industrial circle.The capacity of its most significant end type only is that the space is very limited about 150L; But in order to reach design purpose, the manufacturing cost of this kind of type is very high, is about 2.5 times of its 100L type.In order to increase only 50% practical capacity, but to pay more 150% cost, this obviously is a counterintuitive, does not have what actual application value.
2) certain manufacturer of Europe is developing the industrial type of high capacity, still adopts the design of single inner room.In order to reach the purpose of coupling, its executive component is significantly upgraded, and cost is extremely high, but the precision of its parameter control is very undesirable, and practical effect is unsatisfactory, more can't be used for the medical treatment and the scientific research purposes of requirement harshness.
According to the knowledge of the applicant, go back the design of the ideal high capacity plasma sterilizer of neither one in the world, can't satisfy fairly large sterilization purposes, more can't reach medical treatment, scientific research and industrial blanket expection.This is a global technological gap.
Summary of the invention
The objective of the invention is to solve the defective that the prior art plasma sterilizer can't satisfy fairly large application, the multi-zone separately controlled plasma sterilizer that a kind of cost is low, flexible and convenient to use, can satisfy fairly large application is provided.
The present invention is achieved by the following technical solution:
It is a kind of multi-zone separately controlled plasma sterilizer, comprise inner room and vacuum system, it is characterized in that described inner room is two or more, vacuum system is 1, each inner room is connected with vacuum system by pipeline respectively, is equipped with control valve on the connecting line between each inner room and the vacuum system.
Vacuum system is vacuum pump or vacuum pump group.
Control valve is an autocontrol valve.Autocontrol valve of the present invention can be existing known any motor-operated control valve or pneumatic control valve or their combination, also can be the autocontrol valve of existing known other kinds.
Characteristics of the present invention are resource-sharing, promptly use same set of vacuum system to a plurality of inner rooms difference evacuation, and each inner room can separately use also and can use together; Utilize the time difference in the sterilization process that a plurality of inner rooms are implemented substep control value, make sterilizing efficiency and common single inner room type very approaching, and capacity is bigger, it is more flexible to use.The present invention is infinitely dilatation theoretically, and this is an illusion certainly.And in actual applications, reach 1m
3About practical capacity still very easily, such capacity is very desirable.
Two kinds of control modes are arranged between inner room and the vacuum system, specific as follows:
Scheme one: asynchronous minute prosecutor case.
Having only time of about 1/3 in the sterilization process of plasma sterilizer is at evacuation, and need keep running usually at vacuum pump At All Other Times; In addition, the long and suitable time-delay as required of the interval between several vacuumizing phase in the technology.So if it is poor to use staggered method of dividing control to employ one's time to the best advantage, so, I just can be no more than its maximum carrying capacity and inner room independently separately with three of cover vacuum system outfits.
Consider the job requirement of temperature control system, loading system etc., also less, the more inner room of possible configuration capacity can also further enlarge its total capacity like this.
Scheme two: divide the prosecutor case synchronously.
The exhaust efficiency of vacuum pump changes with vacuum.When pressure was higher, its exhaust efficiency was higher but load is bigger; When pressure was low, its exhaust efficiency was lower but load is less.Therefore, relation according to vacuum, exhaust efficiency and load, use the vacuum line control valve to select different inner room connected state (or single connections in good time, or a plurality of connections), just can give full play to the exhaust efficiency of vacuum pump, and make a plurality of inner rooms reach default vacuum simultaneously in the short period of time.
The present invention has that cost is low, flexible and convenient to use, the advantage of applied range.Use this utility model can solve following problems
1) can solve high capacity plasma sterilizer inner room uneven temperature problem;
2) can solve the not high problem of high capacity plasma sterilizer sterilizing efficiency;
3) can solve the not high problem of high capacity plasma sterilizer control accuracy;
4) can solve the too high problem of high capacity plasma sterilizer vacuum system load;
5) can solve the not high problem of high capacity plasma sterilizer space availability ratio;
6) can solve the problem that the high capacity plasma sterilizer is unsuitable for medical treatment and scientific research purposes.
