Description
Technical field
The utility model is related to a kind of vacuum boiler, more particularly to a kind of compact high efficient vacuum boiler belongs to boiler skill
Art field.
Background technology
Three backhaul vacuum boilers are widely used in a kind of heat transmission equipment of industry and civil field, the common knot of this equipment
Structure is that tube sheet is respectively welded before and after flue, and smoke pipe pipe, setting front smoke box and rear cigarette before and after flue are connected on front and rear tube sheet
Case, front smoke box and rear smoke box are also swivel chamber, the smoke box after burner hearth enters of the flue gas after burning, from rear smoke box by smoke pipe to
The heat exchange of the second backhaul is completed in front smoke box room, then continues the heat exchange of the 3rd backhaul of flowing completion backward by smoke pipe from front smoke box,
Current this commonly used traditional boiler structure has following defect：When the necessary long enough of boiler, because smoke pipe and stove
Courage both ends are fixedly welded on tube sheet, smoke pipe length direction upper smoke tube to flue Constrained stress, when heated, flame
Smoke pipe area is gone to after flue；Flue and smoke pipe all expanded by heating, but flue expansion is more, and smoke pipe expansion is few, so adding
Smoke pipe can form the constraint to flue both ends when hot, in order to reduce destruction of this influence to boiler, it is necessary to make smoke pipe long enough
Influence could be reduced, this structure is limited the length lower limit of boiler；Second is that flue gas of this boiler in heat exchange in tube bank is first
To rear smoke box, tube bank is then entered back into, in order to reduce the energy loss from rear smoke box to tube bank, rear smoke box is generally enough
Long, generally in 500mm or so, this is also limited the length lower limiting value of boiler, is pooled to front smoke box again after tube bank out, then weighs
Next backhaul tube bank is newly assigned to, changes of section is had during flowing, variable cross-section causes vortex area and speed to be divided again
Cloth, generating the fluctuation velocity vertical with flowing to causes resistance to increase, so with larger drag losses during this；
Third, this product is time-consuming when making, the boiler of this three backhaul needs that front and rear smoke box first is welded on pipe when making
Smoke pipe is welded after on plate again, smoke box cannot be carried out at the same time with smoke pipe welding, must be the context of series connection in process, and
Welding job amount is big；Fourth, three current backhaul vacuum boilers generally have two layers of heat-exchanging tube bundle in furnace interior, every layer of tube bank has
The two groups of compositions in left and right, steam rise and complete heat exchange with heat-exchanging tube bundle；Become condensed water along conduit wall surface current after the completion of heat exchange
Get off, when condensed water is cumulative, drop is dropped in lower floor's heat exchange pipe outer wall, is formed moisture film, is seriously affected heat transfer effect, more
It is influenced toward lower floor's tube bank more apparent；Also when steam and condensation water drop same section by and heat occur when meeting hand over
It changes, and matter occurs and changes, that is, become low-quality moist steam.Allow to constantly rise, exchange capability of heat is also faint, and product cross section is
Steam liquid level is smaller, and influence is more apparent, until deteriorating makes steam lose scouring capability, seriously affects the heat exchange efficiency of boiler, institute
A kind of compact, efficient technical solution are needed with three current backhaul vacuum boiler fields.
The content of the invention
The purpose of the utility model is to overcome the above problems present in three current backhaul vacuum boilers, provide one kind
Compact high efficient vacuum boiler.
To realize the purpose of this utility model, following technical solutions is employed：A kind of compact high efficient vacuum boiler, bag
It includes furnace body, be arranged on the in vivo flue of stove and smoke pipe, furnace body internal upper part is provided with heat-exchanging tube bundle, is connected with back after flue
Turn room, smoke pipe is connected in swivel chamber, the smoke pipe is U-shaped, and the rear end of U-shaped smoke pipe is connected in swivel chamber, U-shaped smoke pipe
Front end is hanging, and flue gas enters after swivel chamber completes the second backhaul into U-shaped smoke pipe flow forward, after the front end bending of U-shaped smoke pipe
The 3rd backhaul is completed in flowing backward, and condenser is provided with after swivel chamber, and flue gas enters condenser after completing the 3rd backhaul, changing
The lower part of heat pipe bundle is provided with deflector, and the deflector sets one or more groups of, the multigroup situation of deflector in boiler
It is arranged up and down between lower each group deflector, every group of deflector is made of two pieces of deflectors of left and right settings, between two pieces of deflectors
With gap, one side of two pieces of deflectors is located at the both sides in boiler respectively, and another side is located in boiler, and deflector is located at boiler
In edge be higher than be located at boiler in both sides edge, make two pieces of deflectors in "eight" shape distribution；Further, the U
The smoke pipe of the second backhaul is completed in shape smoke pipe using thread heat exchange pipe, the smoke pipe for completing the 3rd backhaul uses assistant pipe；Described
The length of swivel chamber is less than or equal to 300mm；Further, the length of the swivel chamber is 100mm-150mm；Further,
Multiple holes are provided on the deflector, multiple holes are uniformly distributed in deflector length, and multiple holes are located at close to deflector
The edge of both sides in boiler；Further, multiple holes are bar hole, and the length of bar hole is less than the two of deflector width
/ mono-；Further, the heat-exchanging tube bundle is divided into two layers, respectively upper strata heat-exchanging tube bundle and lower floor's heat-exchanging tube bundle, upper strata
Heat-exchanging tube bundle and lower floor's heat-exchanging tube bundle are made of respectively two groups of heat-exchanging tube bundles, the right heat-exchanging tube bundle group of the left heat-exchanging tube bundle in upper strata and upper strata
Into upper strata heat-exchanging tube bundle, there is gap, the left heat-exchanging tube bundle of lower floor is under between the right heat-exchanging tube bundle of the left heat-exchanging tube bundle in upper strata and upper strata
The right heat-exchanging tube bundle of layer forms lower floor's heat-exchanging tube bundle, has gap, water conservancy diversion between the right heat-exchanging tube bundle of the left heat-exchanging tube bundle of lower floor and lower floor
Plate sets two groups in boiler, and two groups of deflectors are located under upper strata heat-exchanging tube bundle and lower floor's heat-exchanging tube bundle respectively.
The positive advantageous effects of the utility model are：This boiler uses U-shaped smoke pipe, and smoke pipe does not have flue both ends
Restraining force can be mutually independent of each other both in heating process with independently-inflatable in the case where expansion rate is inconsistent, this causes cigarette
The length of pipe can shorten, and can effectively reduce the entire length of boiler；Second is that this design can make the length of swivel chamber
It shortens, the length through testing swivel chamber can shorten to 100mm；Above-mentioned 2 points can effectively make boiler become more compact,
The length of boiler is shortened, makes it that floor space and space reduction to be installed；Third, this boiler on the make swivel chamber and smoke pipe
Welding between tube sheet can be carried out synchronously, and weld seam is few during making, can effectively reduce workload, reduce weld seam number
Amount can also reduce the workload of inspection of the boiler；Fourth, using after deflector, steam is from the gap of two deflectors and bar hole
Middle rising, condensed water are fallen on after falling on deflector, are made no longer to adhere to condensed water on the heat-exchanging tube bundle wall of lower part, will not be reduced
Its heat exchange efficiency, deflector and bar hole setting also reduce the sectional area that condensing meets with steam generation, drop significantly
The amount of heat exchange directly occurs for the low steam risen and the condensed water declined, improves the heat exchange efficiency of boiler.
