Abstract
The utility model discloses a three-passage flow uniformizing part. The three-passage flow uniformizing part is arranged between the outlet of a boiler flue and the inlet air ducts of a first chamber, a second chamber and a third chamber, wherein the inlet of a main body is connected with the outlet side of the boiler flue; a first partition plate and a second partition plate are arranged in the outlet side of the main body for dividing the inner cavity three cavities; and the air ducts of the first chamber, the second chamber and the three chamber are respectively communicated with the three cavities through pipes. The three-passage flow uniformizing part can reduce the difference of smoke flow rate and dust content in each chamber, so that a dust removing apparatus has the balance load distribution in each passage, thereby effectively improving the dust removal efficiency.
Description
Technical field
The utility model relates to the parts in a kind of coal-fired unit flue system, especially relates to three fens flue flow equalizing parts of the coal-fired unit of 1000MW.
Background technology
In the flue system of the coal-fired unit of routine, tend to be provided with deduster, and the interface of this deduster is three, and the exhaust gas volumn that requires three interfaces to enter is uniform distribution, especially in the coal-fired unit of 1000MW, be provided with three chambers in the deduster of its use, because the exhaust gas volumn that unit produces is big, in order better to bring into play the effect of electric precipitation, even for the flow of three chambers distribution in the deduster.Consult Fig. 1 and Fig. 2, during existing flue is arranged, the boiler flue outlet directly is connected on the bottom of vertical bellows 1, on the top of vertical bellows 1 respectively level be provided with and lead to first Room 2, the air channel 5 of second Room 3 and the 3rd Room 4, the boiler flue outlet, the cross section in vertical bellows 1 and air channel 5 is rectangle, many sharp turns, interconnected position, there is flow blind angle, so, because the effect of inertia of ash in the flue gas, boiler smoke exports at boiler flue, when turning in vertical bellows and the air channel, increase in the outside of elbow concentration, inboard concentration reduces, and the height deficiency of vertical bellows 1, the dust that the back centrifugal force of turning causes distributes seriously inhomogeneous, cause entering each indoor tolerance inequality, the flue gas concentration difference, three indoor live loads differ greatly, and have a strong impact on efficiency of dust collection.If come each indoor tolerance of balance by the mode that on air channel 5, increases flow regulator, can increase circulating resistance again, and easy dust stratification.
Summary of the invention
The purpose of this utility model provides and a kind ofly reduces the flue gas deviation, makes each chamber sharing of load equilibrium of cleaner and three fens high flue flow equalizing parts of efficiency of dust collection.
Technical solution of the present utility model is: the equal stream unit of a kind of triple channel, be arranged between the inlet air channel of the boiler flue outlet and first Room, second Room, the 3rd Room, the entrance side of its main body connects described boiler flue outlet, be provided with first dividing plate and the second partition that its inner chamber are separated into three chambers in the outlet side, the air channel of described first Room, second Room and the 3rd Room is communicated with three chambers of main body respectively by pipeline.
By two dividing plates are set in main body, make its inner chamber be separated into three independent cavity, the flue of boiler flue outlet has entered and just has been separated into three strands in the main body like this, finish the distribution of flue gas and dust, make and enter three indoor exhaust gas volumns of deduster and dust content basically identical, effectively reduced each chamber and entered dust content deviation and flow deviation, the sharing of load equilibrium has improved the efficient of dedusting.
Elbow quantity on the pipeline between each described air channel and the described main body is identical respectively.Because it is bigger that elbow accounts for the share of flow resistance, by the elbow quantity between unified each air channel and the main body, the resistance in can each air channel of efficient balance guarantees that flow is even in each air channel, further improves the efficiency of dust collection of whole deduster.
The utility model has the advantages that: reduced entering each indoor flue gas flow deviation and dustiness deviation, made each passage internal loading of cleaner divide balancing, effectively raised efficiency of dust collection.

The specific embodiment
Embodiment:
Consult Fig. 3 and 4, the equal stream unit of a kind of triple channel, be arranged between the inlet air channel 5 of first Room 2, second Room 3, the 3rd Room 4 of boiler flue outlet and deduster, the entrance side of its main body 1 connects described boiler flue outlet, be provided with the air channel 5 that its inner chamber is separated into first dividing plate 7 of three chambers and second partition Room 28, the first, second Room 3 and the 3rd Room 4 is communicated with main body 1 respectively by pipeline three chambers in the outlet side.
In the present embodiment, elbow 9 quantity on the pipeline between each air channel 5 and the main body 1 are identical respectively, all are 2.Because to occupy share less for the resistance of straight tube in the pipeline, though the length of straight pipe that is connected between each air channel 5 and the main body 1 is variant, but this difference is less to the influence of whole pipe internal resistance, and elbow 9 quantity are identical, the quantity of the elbow 9 that comparative resistance is bigger is identical, thereby can guarantee the gas-flow resistance basically identical in every pipeline substantially, corresponding flow also relatively evenly.If accomplish that the resistance in three pipelines is identical, accurately distribute flue gas and dust, can also adjust the gap of first dividing plate 7 and second partition 8, realize thereby change the area of distributing for each air channel.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
Claims (2)
1. equal stream unit of triple channel, be arranged between the inlet air channel of the boiler flue outlet and first Room, second Room, the 3rd Room, it is characterized in that: the entrance side of its main body connects described boiler flue outlet, be provided with first dividing plate and the second partition that its inner chamber are separated into three chambers in the outlet side, the air channel of described first Room, second Room and the 3rd Room is communicated with three chambers of main body respectively by pipeline.
2. the equal stream unit of a kind of triple channel according to claim 1 is characterized in that: the elbow quantity on the pipeline between each described air channel and the described main body is identical respectively.
