Description
Technical field
The utility model relates to a kind of used in nuclear power station dry ice washer, belongs to nuclear power generating equipment technical field.
Background technology
Nuclear power station is in operation and maintenance process, and radioactive substance can deposit gathering on the part of appliance of nuclear power plant system and Work tool, thus forms radioactive pollution.In order to ensure the normal operation of nuclear power plant system and the healthy and safe of operating personnel, the radioactive substance on part of appliance and Work tool must be carried out decontamination process.For this reason, this case produces thus.
Utility model content
The purpose of this utility model is to provide good, the easy to use used in nuclear power station dry ice washer of a kind of clean effect.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of used in nuclear power station dry ice washer, the air compressor comprising vent cabinet and be communicated with successively by pipeline, air accumulator, just imitates air cleaner, cooling driers, high efficiency particle air filter, dry ice cleaner; Purge chamber and exhaust air box is gone out by baffle for separating in vent cabinet, be provided with rotating disk, boom hoisting in purge chamber, and the wall body of purge chamber offers handle hole, in exhaust air box, be provided with the blower fan of band airduct, dividing plate offers air outlet, air outlet is provided with high efficiency particulate air filter; Dry ice spray gun on dry ice cleaner is placed in purge chamber.
As the further setting of such scheme, described high efficiency particulate air filter is positioned at purge chamber.
Described rotating disk is detachable rotating disk, can carry out the rotating disk changing different size, add the hommization of equipment according to the size of cleaning objects and weight.
Described dry ice cleaner adopts variable-frequency motor to control, and can be adjusted by Digital Control and display according to cleaning requirement to dry ice consumption and compressed air.Dry ice cleaner can move easily, can reliably fix again.
The utility model mainly utilizes the dry ice particles of low temperature, under compressed air effect, spray to processed object, make its surface smut sharply be chilled to embrittlement and explosion, after dry ice pellet creeps into dirt crack, distil immediately, its volume instantaneous expansion about 700 times, causes " miniature blast " at shock point place, dirt is taken away body surface, high efficiency particulate air filter purification again in vent cabinet, is discharged in decontamination and hot overhaul shop ventilating system finally by fan action.
The utility model used in nuclear power station dry ice washer, mainly has the following advantages:
1, the mode of decontamination can not produce waste liquid, can not be formed residual at object surface, and this equipment according to in-site installation space flexible arrangement, can reduce equipment occupation space, increases the utilization rate in space; 2, non-secondary pollution; 3, environmental protection cleaning mode, dry ice is recyclable regenerated resources; 4, the utility model is provided with in vent cabinet can, to the boom hoisting needing cleaning objects to lift, not need manpower to lift cleaning objects, just can pass in and out vent cabinet easily with boom hoisting.
In a word, the utility model used in nuclear power station dry ice washer, clean effect is good, simple to operation, environmental protection, take up room little.
The utility model used in nuclear power station dry ice washer is furnished with the dry ice spray gun of plurality of specifications, and clean applications scope is wide, is not only applicable to nuclear power industry, also can be applicable to industry, the industry such as civilian cleans.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of the vent cabinet in Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model used in nuclear power station dry ice washer, the air compressor 1 comprising vent cabinet 7 and be communicated with successively by pipeline, air accumulator 2, just effect air cleaner 3, cooling driers 4, high efficiency particle air filter 5, dry ice cleaner 6.Purge chamber 15 and exhaust air box 16 is gone out by baffle for separating in vent cabinet 7, rotating disk 9, boom hoisting 14 is provided with in purge chamber 15, and the wall body of purge chamber 15 offers handle hole 10(and for staff, hand is stretched in purge chamber 15, to carry out cleaning action), the blower fan 12 of band airduct 13 is provided with in exhaust air box 16, dividing plate offers air outlet, air outlet is provided with high efficiency particulate air filter 11(and is communicated with by high efficiency particulate air filter 11 between purge chamber 15 and exhaust air box 16); Dry ice spray gun 8 on dry ice cleaner 6 is placed in purge chamber 15.Staff carries out decontamination process by the hand-held dry ice spray gun of handle hole 10 8 pairs of object surfaces.
In the present embodiment, boom hoisting 14 is positioned at above rotating disk 9, and rotating disk 9 comprises supporting seat and is positioned at supporting seat top and can carries out the card that rotates by relative support seat.Boom hoisting 14 comprises the slideable chain block be arranged on telescopic slide rail, slide unit on telescopic slide rail can move in the horizontal direction, thus the corresponding wall body in this side of drive chain block turnover vent cabinet 7(vent cabinet 7 offers door), meanwhile, chain block can carry out the movement of horizontal direction by the slide unit on relative telescopic formula slide rail again.
The utility model by dry ice particles high velocity jet to object surface, dry ice transient evaporation is to realize the decontamination process to object surface, the carbon dioxide of dry ice transient evaporation generation is simultaneously after high efficiency particulate air filter 11 purifies, under the effect of blower fan 12, be discharged in decontamination and hot overhaul shop ventilating system by airduct 13.
In the present embodiment, high efficiency particulate air filter 11 is positioned at purge chamber 15.Rotating disk 9 is detachable rotating disk.Dry ice cleaner 6 adopts variable-frequency motor to control.
In order to improve the hommization of equipment, the utility model according to site space flexible arrangement, can reduce equipment occupation space, increases the utilization rate in space.The setting of detachable rotating disk, the rotating disk of conveniently replaced different size, to adapt to the cleaning objects of different size, Different Weight.The boom hoisting 14 be simultaneously provided with in vent cabinet 7, does not need manpower to lift cleaning objects, just can pass in and out vent cabinet 7 easily with boom hoisting 14, make equipment hommization more, facilitate field personnel.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
