Description
Technical field
The invention belongs to field of work machines, relates to a kind of cleaning device, specifically proposes a kind of condenser heat exchanger tube on-line cleaning device.
Background technology
Condenser is the important heat-exchange apparatus of industries such as chemistry, electric power; Wherein inner heat exchanger tube plays the carbonated drink heat exchange action, and condenser is influenced by cooling water and cycle water, can produce dirt in the heat exchanger tube; Not only heat exchange effect reduces; Turbine or steam turbine energy consumption increase, and can cause the heat exchanger tube corrosion leakage when serious, influence Unit Steam Water quality and security of operation.
Keep the cleaning of condenser heat exchanger tube, could guarantee the normal operation of unit.Traditional on-line cleaning method adopts ball cleaning apparatus, and it is few to exist pitching quantity, and ball collecting rate is low; Influence cooling water flow and heat exchange effect when receiving ball; Can not comprehensively clean, particularly inapplicable big capacity unit comes into operation, also need be with defectives such as high pressure water washings in the compressor emergency shutdown maintenance.
A kind of underwater work robot device of on-line cleaning heat exchanger; Comprise walking mechanism, wiper mechanism and controlling organization; Wherein walking mechanism comprises vertical type guide rod and the support road wheel that can do to move horizontally; Vertical type guide rod is made up of one or more hydraulic cylinders, and is up and down through external pressure pump and one or more servo valve and fluid pressure line control hydraulic cylinder; Wiper mechanism comprises a rotary spray gun that can move up and down, and places the vertical type guide rod top, joins with the sparge pipe assembly; Said walking mechanism and wiper mechanism link with controlling organization respectively, through walking mechanism in the controlling organization control water and wiper mechanism laterally with move up and down, be implemented in on-line operation in the condenser water, alternative artificial waterpower cleaning.This invention can reach condenser on-line cleaning effect to a certain extent, but has following problem:
The first, above-mentioned wiper mechanism places the vertical type guide rod top through rotary spray gun, joins with the sparge pipe assembly; With move up and down, belong to point-like or sheet and clean, for the large-scale capacity unit of modernization; Condenser has a plurality of into and out of hydroecium and tens thousand of heat exchanger tubes, adopts pointwise (sheet) cleaning way, and cleaning device is long service cycle; Cleaning efficiency is low, and component wear also can increase.
The second, spray gun exchange heat pipe location difficulty.The tun that condenser water box is a sealing, have press water to flow, quality of cooling water generally contain and are corrosive, and vertical type guide rod is made up of one or more hydraulic cylinders; Up and down through the control of external hydraulic pipeline; Can or contain corrosivity because of water quality inferiority and produce mechanical bite or location difficulty, and there is the girth frame condenser inside, a plurality of mechanisms are movable for a long time; Easy and hydroecium bracing frame collides or wearing and tearing, thereby increases the plant failure probability.
The 3rd, about hydraulic cylinder base must occupy partly with the support walking mechanism and space, the left and right sides heat exchanger tube can occur and clean the blind area, has guaranteed not the comprehensive cleaning of condenser.
The 4th, condenser is in service fine and close scale formation can to occur, and simple water under high pressure cleans and can not guarantee the heat exchanger tube cleaning performance.In addition, water under high pressure is not considered corresponding measure through producing big reaction force behind the spray gun on the device.
The 5th, the apparatus structure more complicated, installation and maintenance is cumbersome.Because unit capacity is different, the condenser water box structure is different, condenser water box internal water flow pressure water flows; Determined that any apparatus structure that moves in inside should not be too complicated; Operation must be solid and reliable, with the minimizing probability of failure, and reduces the negative effect that failover causes condenser.
Summary of the invention
The inventor is in the technical activity of being engaged in chemistry, power industry for many years; The apparatus for work of finding conventional online cleaning heat exchanger tube exists certain defective, and through improving, purpose is to provide a kind of condenser heat exchanger tube on-line cleaning device; Not only relatively simple for structure; Reliable, fault is few, and can comprehensive on-line cleaning.
The technical scheme that the invention is taked is a kind of condenser heat exchanger tube on-line cleaning device of design, and its structure comprises: frame, actuating unit; Transmission mechanism, guiding mechanism, wiper mechanism; Water supply mechanism and controlling organization, wherein, transmission mechanism adopts and is connected turn-screw with the servomotor reducer output shaft of actuating unit; Sheathed transmission nut on turn-screw, in transmission nut outer setting transmission nut flotation chamber, this flotation chamber is communicated with the high-pressure cooling water water supply hose; The guiding mechanism employing parallels with drive lead screw guide post is set, sheathed fairlead on guide post, and in fairlead outer setting fairlead flotation chamber, this flotation chamber is communicated with the high-pressure cooling water water supply hose; Wiper mechanism adopts nozzle row to be communicated with the high-pressure cooling water water supply hose, and the middle part of nozzle row is connected with transmission nut flotation chamber housing, and the nozzle row end is connected with fairlead flotation chamber housing; Serial connection Chemical cleaning blender in the high-pressure cooling water pipeline of water supply mechanism, Chemical cleaning blender one side is communicated with the chemical medicinal cupping.
In said structure, wherein transmission nut flotation chamber, fairlead flotation chamber are employed in transmission nut, fairlead outer setting sealing hydroecium, and the sealing hydroecium is communicated with the high-pressure cooling water water supply hose.
Abovementioned technology is adopted in the invention, prior art improved, because
1, the method for operation changes unidirectional walking manner into; Reduced in condenser inner transverse or vertical transmission and walking mechanism; Through controlling outside servomotor and drive link; The a plurality of relatively-stationary mechanisms of control condenser water box have reduced inner driving joint, water supply line and control circuit, have also reduced the probability of failure that internal interference causes;
2, wiper mechanism changes arrange vertical with moving direction into, and nozzle is the omnidistance distribution of row's shape, can realize the comprehensive cleaning of heat exchanger tube, does not exist and cleans the dead angle, and cleaning rate reaches 100%;
3, reduce parts such as vertical hydraulic cylinder control piper and outside servo valve, reduced probability of failure, convenient for installation and maintenance, can reduce investment outlay and maintenance cost;
4, in transmission mechanism and guiding mechanism, flotation chamber is set; Can not only remove between transmission nut and the turn-screw; Impurity between fairlead and the guide post can also form the high pressure moisture film and overcome the reaction force that water under high pressure produces through nozzle row, keeps transmission mechanism and the smooth and easy operation of guiding mechanism;
5, in water supply water under high pressure pipeline, set up Chemical cleaning blender and chemical medicinal cupping, enlarged cleaning function, can save recondition expense, improve unit and clean operational efficiency for a long time shutting down or not exchange heat pipe keypoint part medicine cleaning between down period.
Compared with prior art, it is simple, reliable, convenient for installation and maintenance to have a device; Both can replace traditional ball cleaning apparatus, and also can cooperate ball cleaning apparatus to use, can comprehensively clean; Again can the keypoint part Chemical cleaning, cleaning speed is fast, the remarkable advantage that cleaning performance is good.
