Description
Technical field
The present invention relates to Industrial Boiler pipe technical field of nondestructive testing, and in particular to a kind of circumferential direction for boiler inside pipe wall
Water knife oxide skin cleaner.
Background technology
With the growth of boiler operation time, oxidation can be increasingly generated inside boiler superheater and high temperature reheater pipeline
Skin, the oxide skin of peeling can block pipeline and cause hot-spot, the peeling of oxide layer, may generate being thinned of boiler pipe fitting,
Deformation, even booster.The another oxide skin for having sub-fraction to come off then enters steamer pusher side with air-flow, may cause stop valve bite
And nozzle of steam turbine, the solid particle erosion of blade damage turbine blade when serious.Up to the present there are no one kind
Effective inner wall oxide skin Removal Technology solves the problems, such as oxide skin that boiler heating surface inside pipe wall is not fallen off.
Invention content
Present invention aim to address above-mentioned the deficiencies in the prior art, provide a kind of circumferential water knife for boiler inside pipe wall
Oxide skin cleaner.
The present invention is achieved by the following technical solutions：
A kind of circumferential water knife oxide skin cleaner for boiler inside pipe wall, including sequentially connected circumferential water jet blade, compound
Conduit and water tank, composite conduit are connect with water tank by fastening screw, and the liquid for water to be pressurizeed is additionally provided in water tank
Pressure device.Water tank is the storage tank for storing Static Water, is pressurizeed by the booster pump in hydraulic device to water, provides high energy
The high pressure water of amount, high pressure water reach circumferential water jet blade by special composite conduit, and circumferential water jet blade utilizes high pressure water conservancy project
Make, the promotion of the reaction force of high pressure water impact power is rotated, and reaches circumferential, the high pressure water to rotate in a circumferential direction constantly washes away heated
The oxide skin that facial canal inner wall is not fallen off, oxide skin come off under the continuous impact of high pressure water.
Preferably, the circumferential water jet blade for four water jet blades with the equidistant formula structural arrangement of spiral together, utilize
When high pressure water works, the promotion of the reaction force of high pressure water impact power is rotated, and reaches circumferential purpose.
Preferably, the composite conduit does inner catheter using high transparency silica gel under vacuum pipe conduit high-pressure air pipe, using hard tube
Formula vacuum tube does outer catheter, and the big good toughness of not only high pressure resistant but also intensity is used in combination in two pipes.
Preferably, the fastening screw is detachable type.
The beneficial effects of the present invention are：
Product of the present invention uses water knife high pressure washing, and the method for shaking and coming off, cleaning are beaten instead of original heating surface tube outer wall
Efficiency significantly improves；Using circumferential cutter head, 360 ° of cleanings of inner wall, clean surface can be increased, clean rate significantly improves；It is main to use
Scour medium of the water as heating surface tube inner wall, will not cause the pollution of heating surface tube inner wall；It can be added in aqueous medium
His chemicals helps boiler to carry out other chemical cleanings.

Specific embodiment
To be best understood from the present invention, with reference to embodiment and attached drawing, the invention will be further described, following embodiment
Only it is that the present invention will be described rather than it is limited.
Apparatus structure：
As shown in Fig. 1 ~ 4, a kind of circumferential water knife oxide skin cleaner for boiler inside pipe wall is cleared up including being used in boiler tube
The circumferential water jet blade 1 of wall oxide skin；For connecting the composite conduit 2 of high pressure water and circumferential water jet blade, compound for connecting
The fastening screw 3 of conduit 2 and water tank 4；It is formed in water tank 4 for generating the hydraulic device 5 of high pressure water.The circumferential direction
Water jet blade be by four water jet blades with the equidistant formula structural arrangement of spiral together, when being worked using high pressure water, high pressure water flushing
The promotion for hitting the reaction force of power is rotated, and reaches circumferential purpose.
Use principle：
The circumferential water jet blade be by four water jet blades with the equidistant formula structural arrangement of spiral together, utilize high pressure water conservancy project
When making, the promotion of the reaction force of high pressure water impact power is rotated, and reaches circumferential purpose；The composite conduit is using " high
Transparent silica gel vacuum tube pipe high-pressure air pipe " does inner catheter, does outer catheter using " hard pipe type vacuum tube ", two pipes are used in combination not
The big good toughness of only high pressure resistant and intensity；The hydraulic device pressurizes to water by hydraulic device, provides high-energy
High pressure water；The water tank is the storage tank of Static Water.
Application method：
1. before the work of circumferential water knife oxide skin cleaner, water tank 4 is injected into a certain amount of water and passes through fastening screw 3 connect
Connect instrument；
2. composite conduit 2 is stretched into steel duct for clearance；
3. by controlling motor that the water knife booster pump in hydraulic device 5 is increased to suitable pressure value；
4. after starting cleaning switch, the high pressure water being pressurized can be transmitted to water jet blade, circumferential water jet blade by composite conduit 2
1 can beat high pressure water in the oxide skin of the steel pipe inner wall of cutter head position, and then the position oxide skin is cleared up；
5. composite conduit 2 is slowly evenly pulled out from steel duct, achieve the purpose that the entire steel pipe inner wall of cleaning.
By above technical scheme it is found that the present invention can improve boiler in the oxide skin that boiler tube inner wall cleaning is not fallen off
The heat exchanger effectiveness of heating surface tube and the service life for increasing heating surface tubes in boilers reduce boiler heating surface booster risk.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain that claims of the present invention determines.
