Abstract
The utility model discloses a chain boiler coal conveying pipeline cushions voltage regulator device installs in coal conveying pipeline, including buffer case, buffer case passes through the crown plate at both ends and installs in coal conveying pipeline to realize the intercommunication with coal conveying pipeline, the through -flow sectional area of buffer case is 1.5~3 times of the through -flow sectional area of coal conveying pipeline, the further improvement lies in: be equipped with flow control valve among the coal conveying pipeline. The utility model discloses the pressure oscillation of reduction coal conveying pipeline be can show, homogeneity, the moving stationarity of chain boiler burning are being improved.
Description
Technical field
This utility model relates to coal-burning boiler field, particularly relates to a kind of chain-grate boiler coal dust transfer pipeline.
Background technology
Small and Medium Enterprises in China produces and concentrated supply of heating in the city boiler is based on coal-burning boiler at present, wherein most is chain-grate boiler, for improving efficiency of combustion, existing chain-grate boiler is typically equipped with pulverized coal grinding machine, after coal is worn into coal dust, will be inputted in chain-grate boiler burner hearth after breeze atomizing by coal dust transfer pipeline.Existing coal dust transfer pipeline from pulverized coal grinding machine to chain-grate boiler between substantially use equal pipe, this pipeline structure is simple, but the inhomogeneities due to ature of coal, the probability that detonation occurs in igniter exit is the biggest, the pressure oscillation in conveyance conduit certainly will be caused, the thin film that abnormal impurity in pipe is the most polished, braid over braid, other filament can block pipeline, could must solve after hearth combustion brought into by flow spoiler, thus also can cause pressure oscillation at short notice, these pressure oscillations all can affect the uniformity of chain boiler combustion, affect the even running of chain-grate boiler.
Summary of the invention
This utility model, for the deficiencies in the prior art, proposes a kind of chain-grate boiler coal dust transfer pipeline buffering stable-pressure device substantially reducing coal dust transfer pipeline pressure oscillation.
This utility model is achieved through the following technical solutions technical goal.
Chain-grate boiler coal dust transfer pipeline buffering stable-pressure device, it thes improvement is that: be arranged in coal dust transfer pipeline, including dsah-pot；Described dsah-pot is arranged in coal dust transfer pipeline by the ring flat-plate at two ends, and realizes the connection with coal dust transfer pipeline；Described dsah-pot cross-sectional flow area is 1.5～3 times of coal dust transfer pipeline cross-sectional flow area.
In said structure, described coal dust transfer pipeline is provided with flow control valve.
This utility model compared with prior art, has the positive effect that:
1. during dsah-pot is arranged on coal dust transfer pipeline, dsah-pot cross-sectional flow area is 1.5～3 times of coal dust transfer pipeline cross-sectional flow area, so, the coal dust entering dsah-pot obtains more sufficiently buffering, coal dust transfer pipeline pressure oscillation can be substantially reduced, improve the uniformity of chain boiler combustion, the stationarity of operating.
2. coal dust transfer pipeline is provided with flow control valve, by the pressure in regulation Flow-rate adjustment coal dust transfer pipeline.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below according to accompanying drawing and the utility model is described in further detail in conjunction with the embodiments.
The transfer pipeline of chain-grate boiler coal dust shown in accompanying drawing buffering stable-pressure device, is arranged in coal dust transfer pipeline 1, including dsah-pot 2；Dsah-pot 2 is arranged in coal dust transfer pipeline 1 by the ring flat-plate 2.1 at two ends, and realizes the connection with coal dust transfer pipeline 1；Dsah-pot 2 cross-sectional flow area is 1.5～3 times of coal dust transfer pipeline 1 cross-sectional flow area.
Coal dust transfer pipeline 1 is provided with flow control valve 3.
Claims (2)
1. a chain-grate boiler coal dust transfer pipeline buffering stable-pressure device, it is characterised in that: it is arranged in coal dust transfer pipeline (1), including dsah-pot (2)；Described dsah-pot (2) is arranged in coal dust transfer pipeline (1) by the ring flat-plate (2.1) at two ends, and realizes the connection with coal dust transfer pipeline (1)；Described dsah-pot (2) cross-sectional flow area is 1.5～3 times of coal dust transfer pipeline (1) cross-sectional flow area.
