Background technology
Because the steam generator tube sheet is the border of a loop and secondary circuit in the nuclear power main equipment, and is the critical component of whole steam generator reliability service, therefore, can the oil stain that remove the tube sheet surface thoroughly, reliably be directly connected to the nuclear power operation.But; In order to guarantee the size and the precision of pore processing, use cutting oil inevitably, especially in the bigger tube sheet of radius-thickness ratio during drilling of tubesheet; The situation that exists oil stain to be difficult to clean up is needed the degreasing unit of the ultra thick tube sheet of the large-scale porous of a kind of special cleaning badly.
The utility model content
The technical problem that the utility model will solve is: a kind of simple in structure, safe ultra thick tube sheet porous degreasing unit is provided.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
Ultra thick tube sheet porous degreasing unit; Comprise the fuel tank of usheing to seat, also comprise that one is sealed and matched form to remove the hood of grease chamber with the said fuel tank of usheing to seat; The inwall of said hood is provided with the oil removing liquid-transport pipe-line, is distributed with the shower nozzle that ultra thick tube sheet is cleaned in a plurality of confessions on the said oil removing liquid-transport pipe-line, and an end of said oil removing liquid-transport pipe-line extends hood and is externally connected with feed tube; Usher to seat fuel tank bottom is provided with a liquid outlet; Said liquid outlet is connected with a circulating pump, and said circulating pump is connected with feed tube through a degreasing fluid filter, and said circulating pump control end is electrically connected with the controller of its work of control.
Further as improving, this degreasing unit also comprises an inert gas qi of chong channel ascending adversely device, and this inert gas qi of chong channel ascending adversely device inserts through inert gas piping and removes in the grease chamber.
Further, also be provided with the safety valve of an assurance oil removing office work air pressure safety on the said hood as preferred embodiment.
The beneficial effect of the utility model is: the utility model degreasing unit; After the degreasing fluid that is injected into the fuel tank of usheing to seat is forced into flushing pressure through circulating pump; Through the shower nozzle on the oil removing liquid-transport pipe-line oil removing is carried out in the hole on the ultra thick tube sheet and cleaned, easy to operate, cleaning performance is good; Between circulating pump and feed tube, also be provided with one separate foreign material and oil stain the degreasing fluid filter, strengthened the cleaning performance of degreasing fluid.
Further; In order to guarantee degreasing unit security in the course of the work; Added inert gas qi of chong channel ascending adversely device, before the ON cycle pump carries out the degreasing fluid spray, earlier to the indoor part inert gas that pours of oil removing; With the indoor amount of inert gas that certain proportion and certain pressure are arranged of assurance oil removing, thereby guarantee the safe and reliable of oil removing process.
Description of drawings
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Fig. 1 is the structural representation of the ultra thick tube sheet porous degreasing unit of the utility model.
The specific embodiment
With reference to Fig. 1; This degreasing unit comprises the fuel tank 1 of usheing to seat, also comprises that one is sealed and matched form to remove the hood 3 of grease chamber 2 with the said fuel tank 1 of usheing to seat; The inwall of said hood 3 is provided with oil removing liquid-transport pipe-line 4, is distributed with the shower nozzle 41 that ultra thick tube sheet is cleaned in a plurality of confessions on the said oil removing liquid-transport pipe-line 4, and an end of said oil removing liquid-transport pipe-line extends hood 3 and is externally connected with feed tube 5; Fuel tank 1 bottom of usheing to seat is provided with a liquid outlet 11; Said liquid outlet 11 is connected with a circulating pump 6, and said circulating pump 6 is connected with feed tube 5 through a degreasing fluid filter 7, and said circulating pump 6 control ends are electrically connected with the controller 8 of its work of control.This device also comprises an inert gas qi of chong channel ascending adversely device 9, and this inert gas qi of chong channel ascending adversely device 9 inserts through inert gas piping 91 and removes in the grease chamber 2.
The course of work of this degreasing unit is following:
Ultra thick tube sheet 10 to be cleaned is hung in the fuel tank 1 of usheing to seat, then the hood 3 and the fuel tank 1 of usheing to seat is sealed and matched, do not produce any seepage between the fuel tank 1 in order to guarantee hood 3 and to usher to seat, hood 3 with usher to seat be connected with screw between the fuel tank 1 also fastening; Open inert gas qi of chong channel ascending adversely device 9, remove grease chamber's qi of chong channel ascending adversely, guaranteeing the indoor amount of inert gas that certain proportion and certain pressure are arranged of oil removing, thereby guarantee that the oil removing process carries out safely through 91 pairs of inert gas pipings; ON cycle pump 6; Degreasing fluid in the fuel tank 3 of usheing to seat is got into oil removing liquid-transport pipe-line 4 through degreasing fluid filter 7, feed tube 5; Circulating pump 6 is high-pressure pump (a stainless steel pressure pump); Guarantee that the degreasing fluid in the oil removing liquid-transport pipe-line 4 is forced into flushing pressure, carry out oil removing through 41 pairs of ultra thick tube sheets 10 of a plurality of shower nozzles on it and clean.Therefore degreasing fluid can circulate and constantly clean through 41 pairs of ultra thick tube sheets 10 of shower nozzle, and degreasing fluid filter 7 can filter carrying out essence from the degreasing fluid in the fuel tank 3 of usheing to seat, and separates foreign material and oil stain, to improve cleaning performance.
The process of oil removing can be controlled the time of automatic setting oil removing through the program in the controller 8.Controller 8 can also carry out security control to following aspect, and makes light indication, warning and stoppage protection respectively, for example: detect to remove the pressure, the liquid level in the fuel tank, the temperature of degreasing fluid, the filter capacity of degreasing fluid filter 7 of grease chamber etc.
