Description
Technical field
It the utility model is related to a kind of waste heat boiler, more particularly to a kind of new double-barrel transverse formula efficient waste-heat boiler.
Background technology
Usual thermal source uses horizontal single flue or Multi-flue to arrange more for the waste heat boiler of gas medium, the superheater of boiler,
The part dispersed placement such as convection bank, economizer, heating surface are generally light-pipe structure；Flying dust in its dedusting Main Basiss flue
Natural subsidence, effect is poor, and easily forms flue gas partial short-circuit, reduces the heat transfer efficiency of heating surface, and huge structure, multiple
It is miscellaneous, floor space is big, cost is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new double-barrel transverse formula efficient waste-heat boiler, this
Boiler uses double barrel structures, convection bank up and down that upper drum is connected with lower drum by expanded joint form, and economizer uses film
Formula structure, two-stage dust separating device is formed by water cooled membrane wall.
Adopted the following technical scheme that to solve above-mentioned technical problem the utility model：A kind of new double-barrel transverse formula is efficient
Waste heat boiler, including basic, preceding furnace wall, upper drum and lower drum, upper drum and lower drum are communicated by convection bank, preceding furnace wall
It is internally provided with superheater, offers smoke inlet on described preceding furnace wall at lower drum, close to upper drum on the furnace wall of left side
Place offers outlet flue, is provided with evaporating heating surface flue between upper drum and lower drum, convection bank be arranged in evaporation by
In hot face flue；Burner hearth flue is provided with front side of evaporating heating surface flue, rear side is provided with back-end surfaces flue；Superheater is arranged in
In burner hearth flue, economizer is arranged in back-end surfaces flue；Lower drum both sides are respectively arranged with one-level dust separating device
With two level dust separating device.
Described evaporating heating surface flue, burner hearth flue, back-end surfaces flue form by membrane wall mid-feather.
By middle prepattern wall mid-feather, the rear membrane wall mid-feather with forms described evaporating heating surface flue；Burner hearth
Flue is made up of prepattern wall mid-feather and middle prepattern wall mid-feather；Back-end surfaces flue rear membrane wall flue in
Partition wall and rear membrane wall mid-feather composition.
Described one-level dust separating device is by lower drum, prepattern wall mid-feather and middle prepattern wall mid-feather group
Into, two level dust separating device by lower drum, in after membrane wall mid-feather and rear membrane wall mid-feather form.
Described convection bank is connected between upper drum and lower drum by expanded joint form, and vertical in-line arrangement is in evaporation
In heating surface flue, four deflection plates centre bafflings of flue gas are used to improve flue gas flow rate and form transversal flow.
After technical scheme described in the utility model, because convection bank is using baffling among four deflection plates of flue gas
To improve flue gas flow rate and form transversal flow, the heat-transfer capability of convection bank is improved, while using W types flue, double drums
Horizontal arrangement, one-level dust separating device and two level dust separating device are formed in the bottom of W type flues, heating surface, which has, both to be passed
Heat is again every the multifunctionality of cigarette.Economizer in back-end ductwork uses membrane type structure, adds economizer heat exchange area.Due to right
Flowing bundle connects upper drum with lower drum by expanded joint form, and working medium is between convection bank, upper drum and upper drum three
Reliable Natural Circulation is formed by density contrast, it is not necessary to configures down-comer and steam guiding tube.So, this waste heat boiler can reach high
Effect heat transfer, in two-stage stove flue dust separation function, have that compact-sized, cost is low, floor space is small and efficient, environmentally friendly, energy-conservation
The advantages that.
Brief description of the drawings
Fig. 1 is the utility model front view structure sectional view.
Fig. 2 is the utility model plan structure sectional view.
Embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment
As shown in accompanying drawing 1-2, a kind of new double-barrel transverse formula efficient waste-heat boiler, boiler body is placed in coagulation soil matrix
On plinth (1), smoke inlet (2) is opened in close lower drum (4) place of preceding furnace wall (5), and flue gas enters boiler main from smoke inlet (2)
Body, the lower section for the burner hearth flue (6) being made up of prepattern wall mid-feather (7) and middle prepattern wall mid-feather (9) is by cooking
The one-level dust separating device (3) of cylinder (4), prepattern wall mid-feather (7) and middle prepattern wall mid-feather (9) composition, cigarette
Gas falls into one-level cigarette upwardly through burner hearth flue (6), flying dust by the o of one-level dust separating device (3) rear steering 90 due to inertia
Dust separating device (3) bottom, superheater (8) are arranged in burner hearth flue (6).Flue gas is upwardly through superheater (8) rear steering 90
O is back into evaporating heating surface flue (11), and evaporating heating surface flue (11) is by middle prepattern wall mid-feather (9) and middle caudacoria
