Description
Technical field
The present invention relates to boilers to assist heat collector technical field, more particularly to a kind of boiler superheater.
Background technique
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy, high-temperature flue gas in fuel
The forms such as thermal energy, and pass through boiler and convert, output outward has steam, high-temperature water or the organic heat carrier of certain thermal energy, extensively
It is general to be used for thermal power station, ship, locomotive and industrial and mining enterprises.
The main operational principle of boiler is a kind of waste heat biography using in the thermal energy discharged after fuel combustion or industrial production
The water in container is passed, the heat power equipment of temperature required for reaching water or certain pressure steam.Wherein boiler superheater is
More important auxiliary heat collector in large-sized boiler vapour system, boiler superheater are recycling boiler smoke energy, are made
The steam that boiler comes out can be heated, and dry saturated steam is become, and be conducive to improve boiler thermal efficiency, be also beneficial to steam turbine and keep away
Exempt from water attack.But the boiler superheater of the prior art generally uses snake pipe structure, therefore is easy when giving boiler feedwater
Salification or dust on the tube wall of snake pipe if things go on like this will result in serious salification in superheater, because of superheater pipeline knot
Structure is complicated, while institute's salt scale coagulation not readily dissolves, therefore traditional purging method is difficult to protecting again by the baking of continuous high temperature
The salt crust of tube wall is effectively removed while demonstrate,proving boiler thermal efficiency, and washing time is long, water consumption is big, perishable pipeline.
Therefore, to solve the above problems, the present invention provides a kind of boiler superheaters.
Summary of the invention
The object of the present invention is to provide a kind of boiler superheaters, optimize superheater structure, increase Backwash pipeline realization
The iterative cycles of helix tube rinse, and reduce washing time and water consumption, at low cost.
Used technical solution is the present invention in view of the above technical defects:
A kind of boiler superheater, including helix tube, the helix tube are double-spiral structure, are followed successively by spiral I from inside to outside
With spiral II, the spiral I is in symmetrical U-shaped flat spin by starting point of Single port, and the spiral II is using spiral I as reference
Object is surrounded on the outside of the spiral I, is provided with range difference between the spiral I and spiral II.
Further, symmetrically there is one group on the turning between the beginning of the spiral II, terminal and beginning and terminal
Backwash pipeline.
Further, several groups Backwash pipeline is interspersed.
Further, expansion clearance is provided on the spiral II between every two groups of Backwash pipelines.
Further, the terminal of the helix tube is provided with backwash connector.
Further, the backwash connector is a hollow ball, and the diameter of sphere is greater than the diameter of helix tube.
A kind of back-flushing method of boiler superheater is added sodium hydroxide or ammonium hydroxide etc. in backwash water source and adjusts water source
PH value, make water source in alkalinity, then alkaline water source is carried out heating deoxygenation processing, then connect the backwash connector of helix tube
Water source finally carries out iterative cycles flushing from the terminal of helix tube using high pressure in Backwash pipeline.
The beneficial effects of the present invention are: the present invention optimizes superheater structure, using double-spiral structure, by spiral II
The several groups that are staggered Backwash pipeline realizes that the iterative cycles of helix tube rinse, and reduces traditional back-flushing method bring punching
The drawbacks of time is long, water consumption is big and perishable pipeline is washed, economic and social benefit is good.
Detailed description of the invention
Present invention is further described in detail with reference to the accompanying drawings and detailed description
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is another structural schematic diagram of the invention.
Wherein: 1, helix tube, 2, range difference, 3, Backwash pipeline, 4, expansion clearance, 5, backwash connector, 11, spiral I,

Specific embodiment
A kind of boiler superheater as depicted in figs. 1 and 2, including helix tube 1, helix tube 1 is double-spiral structure, by introversion
It is followed successively by spiral I11 and spiral II12 outside, spiral I11 is in symmetrical U-shaped flat spin, spiral II12 by starting point of Single port
It is surrounded on the outside of spiral I11 using spiral I11 as object of reference, range difference 2 is provided between spiral I11 and spiral II12.
In the present embodiment, symmetrically have one on the turning between the beginning of spiral II12, terminal and beginning and terminal
Group Backwash pipeline 3, for conveying backwash water source.
In the present embodiment, several groups Backwash pipeline 3 is interspersed, and is easy to implement backwash water source to helix tube 1
Iterative cycles rinse.
In the present embodiment, it is provided with expansion clearance 4 on the spiral II12 between every two groups of Backwash pipelines 3, to
Certain space is provided for the thermal expansion of helix tube 1, also plays the role of masking protection for helix tube 1.
In the present embodiment, the terminal of helix tube 1 is provided with backwash connector 5, is used to connect high pressure backwash water source,
And backwashing connector 5 is a hollow ball, and the diameter of sphere is greater than the diameter of helix tube 1, and certain put down is played in pressure
Weighing apparatus effect, reducing leads to the phenomenon that helix tube 1 is with the explosion of high pressure water junction because the pressure of high pressure water is excessive, highly-safe.
In the present embodiment, a kind of back-flushing method of boiler superheater, backwash water source in be added sodium hydroxide or
Ammonium hydroxide etc. adjusts the pH value at water source, makes water source in alkalinity, then alkaline water source is carried out heating deoxygenation processing, then by helix tube
It backwashes connector and connects water source, finally carry out iterative cycles flushing in Backwash pipeline from the terminal of helix tube using high pressure.
The beneficial effects of the present invention are: the present invention optimizes superheater structure, using double-spiral structure, by spiral II
The several groups that are staggered Backwash pipeline realizes that the iterative cycles of helix tube rinse, and reduces traditional back-flushing method bring punching
The drawbacks of time is long, water consumption is big and perishable pipeline is washed, economic and social benefit is good.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
