Description
Technical field
The utility model relates to field of boilers, prevent boiler export expansion joint dust stratification structure more particularly, to one kind.
Background technique
Existing boiler export expansion joint position horizontal space is big, when high-temperature flue gas passes through, if dust content is big, and sedimentation
The cigarette ash to get off is difficult nature and is entrained by the flow of air, such as Fig. 1；It is logical to be higher than next stage electricity dust collecting system flue gas when boiler export designs
Road, high-temperature flue gas needs are walked from top to bottom, increase the loss of negative pressure, so exacerbate the dust stratification shape in this position
Condition.But due to the hot expansibility of boiler, expansion joint must retain.Find that boiler export expansion joint position exists after analysis
The defect of the following aspects.
1. boiler export expansion joint horizontal segment is too long, there are the objective condition of dust stratification but also bad cleanings；
2. boiler export and electricity gather dust, there are normal throws for import, are unfavorable for flue gas circulation, additional negative pressure is caused to lose.
Utility model content
Technical problem to be solved by the utility model is: overcoming the deficiencies of the prior art and provide a kind of neither change boiler
The inherent function of expansion joint is exported, and can solve the boiler export expansion joint structure of expansion joint dust stratification problem.
The technical scheme adopted by the utility model to solve the technical problem is as follows: one kind prevents boiler export expansion joint dust stratification
Structure, including boiler export, expansion joint, excessive straight section, sedimentation bucket and shoot door, the side of shoot door is provided with swollen
Swollen section, the other side of shoot door are equipped with sedimentation bucket, and the expansion joint is connected by excessive straight section with boiler export, described
The length of excessive straight section is 10cm.
Further, sedimentation bucket top is equipped with electricity and gathers dust import, the electricity gather dust import height than boiler export
Height is high.
Further, the expansion joint includes left ring flat-plate and right ring flat-plate, and left ring flat-plate passes through nonmetal flexible circle band and right ring flat-plate
It is formed and is tightly connected.
Further, it is equipped with left adapter tube on the inside of the left ring flat-plate, opposite position is equipped with right adapter tube, left adapter tube on the inside of right ring flat-plate
It is connected with right adapter tube by sealing ring.
Further, high-temperature-resistant thermal-insulation material is filled between the nonmetal flexible circle band and left adapter tube and right adapter tube.
Further, the high-temperature-resistant thermal-insulation material is alumina silicate fibre or ceramic fibre.Silicic acid is selected in the present embodiment
Aluminum fiber.
The utility model has the beneficial effects that
The utility model solves the problems, such as that boiler export expansion joint position is easy dust stratification, and is convenient to clean possible product
Ash improves the unimpeded of flue, so as to improve the production environment of boiler.

Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Referring to Fig. 2 and Fig. 3: one kind preventing boiler export expansion joint dust stratification structure, including boiler export 4, expansion joint 2, mistake
Straight section 3, sedimentation bucket 1 and shoot door 5 are spent, the side of shoot door 5 is provided with expansion joint 2, the other side installation of shoot door 5
There is sedimentation bucket 1, expansion joint 2 is connected by excessive straight section 3 with boiler export 4, and the length of excessive straight section 3 is 10cm.
By adjusting the positional relationship of shoot door 5 and expansion joint 2, reduce excessive between expansion joint 2 and boiler export 4
The length of excessive straight section 3 is reduced 10cm till now, the change of excessive 3 length of straight section from pervious 50cm by the length of straight section 3
It is short, reduce the time that flue gas passes through excessive straight section 3, avoids flue gas dust stratification at excessive straight section 3 to a certain extent.Excessive
The flue dust that straight section 3 and expansion joint 2 accumulate can be cleared up by shoot door 5.
Flue gas comes out from expansion joint 2 to be entered electricity and gathers dust import (not shown), and the gather dust height of import of electricity is higher by boiler and goes out
The height of mouth 4, is conducive to the entrance of flue gas.Dust-laden in flue gas is being formed by non-uniform electric field by high-voltage DC power supply,
The cathode of power supply is known as cathode, and the anode of power supply is known as anode, the electric field when voltage is increased to certain numerical value, near cathode
Intensity forces gas to collide ionization, forms a large amount of negative ions.Since the cation near cathode tends to the road of cathode
Journey is extremely short, and speed is low, and the chance for running into dust is seldom, and therefore, most dust bump against with the long anion of distance and taken
Negative electricity flies to anode, and only only a few dust product is in cathode, and regular rapping anode and cathode, it is heavy that the dust of the two poles of the earth absorption is fallen into
In drop bucket 1, the setting of sedimentation bucket 1 is for the dust accumulation in centralized collection flue gas, convenient for carrying out unified processing to dust stratification.
Expansion joint 2 includes left ring flat-plate 21 and right ring flat-plate 27, and left ring flat-plate 21 passes through nonmetal flexible circle band 24 and right ring flat-plate 27
It is formed and is tightly connected, left adapter tube 22 is equipped on the inside of left ring flat-plate 21, right 27 inside opposite position of ring flat-plate is equipped with right adapter tube 26, and a left side connects
Pipe 22 is connected with right adapter tube 26 by sealing ring 25, is filled between nonmetal flexible circle band 24 and left adapter tube 22 and right adapter tube 26
There is high-temperature-resistant thermal-insulation material 23, high-temperature-resistant thermal-insulation material 23 can be alumina silicate fibre or ceramic fibre, in the present embodiment,
High-temperature-resistant thermal-insulation material 23 selects alumina silicate fibre, and 25 Ceramics fibrous encapsulation circle of sealing ring, nonmetal flexible circle 24 is with choosing
With fluorubber band.
