Description
Technical field
The utility model is related to Industrial Boiler pipe technical field of nondestructive testing, and in particular to a kind of for boiler inside pipe wall
Circumferential 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 will produce being thinned of boiler tube part,
Deformation, even booster.The another oxide skin for having sub-fraction to fall 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.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of circumferential direction for boiler inside pipe wall
Water knife oxide skin cleaner.
The utility model is achieved through 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,
Composite conduit and water tank, composite conduit are connect with water tank by fastening screw, are additionally provided in water tank for water to pressurize
Hydraulic device.Water tank is the storage tank for storing Static Water, is pressurizeed, is provided to water by the booster pump in hydraulic device
The high pressure water of high-energy, high pressure water reach circumferential water jet blade by special composite conduit, and circumferential water jet blade utilizes high pressure
Water conservancy project is made, and 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
The oxide skin that heating surface tube inner wall is not fallen off, oxide skin fall off under the continuous impact of high pressure water.
Preferably, the circumferential water jet blade be 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 circumferential purpose is reached.
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 utility model are：
The utility model product uses water knife high pressure washing, and the side that vibrations fall off is beaten instead of original heating surface tube outer wall
Method, cleaning efficiency significantly improve；Using circumferential cutter head, 360 ° of cleanings of inner wall, clean surface can be increased, clean rate significantly improves；
Scour medium of the water as heating surface tube inner wall is mainly used, the pollution of heating surface tube inner wall will not be caused；It can be in aqueous medium
Middle other chemicals of addition help boiler to carry out other chemical cleanings.

Specific implementation mode
To be best understood from the utility model, the utility model is further described with reference to embodiment and attached drawing, with
Lower embodiment is only to illustrate to the utility model rather than be limited to it.
Apparatus structure：
As shown in Fig. 1 ~ 4, a kind of circumferential water knife oxide skin cleaner for boiler inside pipe wall, including be used to clear up boiler
The circumferential water jet blade 1 of inside pipe wall oxide skin；For connecting the composite conduit 2 of high pressure water and circumferential water jet blade, for connecting
The fastening screw 3 of composite conduit 2 and water tank 4；It is formed in water tank 4 for generating the hydraulic device 5 of high pressure water.Described
Circumferential 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
The promotion of the reaction force of hydraulic impact is rotated, and circumferential purpose is reached.
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
When water conservancy project is made, the promotion of the reaction force of high pressure water impact power is rotated, and reaches circumferential purpose；The composite conduit uses
" high transparency silica gel under vacuum pipe conduit high-pressure air pipe " does inner catheter, does outer catheter using " hard pipe type vacuum tube ", two pipes are compound to be made
With the big good toughness of not only high pressure resistant but also intensity；The hydraulic device pressurizes to water by hydraulic device, provides high energy
The high pressure water of amount；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 by fastening spiral shell
Silk 3 connects instrument；
2. composite conduit 2 to be stretched into steel duct for clearance；
3. the water knife booster pump in hydraulic device 5 is increased to suitable pressure value by controlling motor；
4. after starting cleaning switch, the high pressure water being pressurized can be transmitted to water jet blade, circumferential water knife by composite conduit 2
Cutter head 1 can beat high pressure water in the oxide skin of the steel pipe inner wall of cutter head position, and then be carried out to the position oxide skin clear
Reason；
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 utility model can be improved in the oxide skin that boiler tube inner wall cleaning is not fallen off
The heat exchanger effectiveness of heating surface tubes in boilers and the service life for increasing heating surface tubes in boilers reduce boiler heating surface booster risk.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
