A seal between T-shaped water-cooling wall, connects side water wall and partition wall water-cooling wall for " T " font joint.T-shaped seal by sealing fin A, sealing fin B, sealing fin C and semi arch seal and form, one end of sealing fin A and sealing fin B is connected to the two ends of semi arch sealing, and one end of sealing fin C is then connected to top, semi arch sealing middle part.Seal fin A and seal the angle between fin C, the angle between sealing fin B and sealing fin C for being 90 °.The diameter of semi arch sealing equals the diameter of water screen tube.All connections between semi arch sealing, sealing fin A, sealing fin B, sealing fin C, water screen tube, water screen tube fin are welding.Between water-cooling wall provided by the invention seal have absorb expansion character good, be convenient to processing and manufacturing, be convenient to the advantages such as installation, the seamless seal be specially adapted between Industrial Boiler side water wall with partition wall water-cooling wall is connected.
Description
Technical field
The present invention relates to the sealing between a kind of water-cooling wall, particularly relate to the seal that the T-shaped docking of a kind of water-cooling wall connects, belong to boiler technology field.
Background technology
Water-cooling wall is the evaporating heating surface of fire coal, fuel oil, combustion gas, combustion solid waste boiler, is made up of pipe and fin.Connection between water-cooling wall and water-cooling wall relates to thermal expansion problem, if solve bad, boiler in the processes such as startup, blowing out, because thermal stress will draw bad water screen tube, particularly in T-shaped seam and the easier drawing crack of water screen tube being connected part of side water wall and partition wall water-cooling wall.Chinese patent ZL97103977.1 discloses a kind of incinerator, Chinese patent CN200510126362.6 discloses a kind of Horizontal type circulating fluid bed combustion apparatus and circulating combustion method thereof, in these boilers, all encounter the problem that side water wall is connected with partition wall water-cooling wall, and in actual motion, also all occur the drawing crack problem that water-cooling wall thermal stress causes.For the sealing problem connected between water-cooling wall, importantly will solve thermal expansion problem, namely sealing device is except ensureing sealing, and also wanting can absorbing thermal expansion.Chinese patent CN201715483U discloses a kind of seal of boiler tube place, adopts seal box and multiple straight connector to carry out, but is not suitable for the elastic packing between water screen tube.Chinese patent CN202092106U discloses the sealing mechanism between a kind of furnace arch, furnace nose and rear wall cigarette well front wall, utilizes flanged plate to seal and absorbs deformed dilation.The sealing device of prior art is not specially adapted to the sealing between the T-shaped connection of water-cooling wall and absorbs expand.
Summary of the invention
For shortcomings and deficiencies of the prior art, the object of the present invention is to provide that a kind of structure is simple, sealing property be connected with the good T-shaped water-cooling wall of absorbing thermal expansion performance between seal.
The present invention is achieved by the following technical solutions:
Seal between a kind of T-shaped water-cooling wall, be arranged in the T connector place between side water wall and partition wall water-cooling wall be made up of cold wall pipe and water screen tube fin, it is characterized in that: described T-shaped seal forms by sealing fin A, sealing fin B, sealing fin C and semi arch sealing, one end of described sealing fin A and sealing fin B is connected to the two ends of semi arch sealing, and one end of sealing fin C is connected to top, semi arch sealing middle part; Sealing fin A, sealing fin B are connected with the water screen tube of side water wall or partition wall water-cooling wall respectively with the other end of sealing fin C; Angle between sealing fin A and sealing fin C is 90 °, and the angle between sealing fin B and sealing fin C is 90 °.The diameter of described semi arch sealing equals the diameter of water screen tube, the width L3 of the width L1 of sealing fin A, the width L4 of sealing fin B, sealing sealing fin C is equal, and be all less than the width L1 of water screen tube fin, i.e. L2=L3=L4<L1.By being weldingly connected between semi arch sealing, sealing fin A, sealing fin B, sealing fin C, water screen tube, water screen tube fin.
The present invention compared with prior art, has the following advantages and high-lighting effect: 1. absorbing thermal expansion performance is good.2. be convenient to install and processing, total tune is good.3. the rigidity keeping water-cooling wall is easy to.

Detailed description of the invention
Concrete structure of the present invention, operation principle and embodiment is described in detail below in conjunction with accompanying drawing:
Fig. 1 is the T-shaped connection diagram of water-cooling wall involved in the present invention, Fig. 2 be the A-A of Fig. 1 to schematic diagram, Fig. 3 is the seal schematic diagram between a kind of T-shaped water-cooling wall involved in the present invention.T connector place between the side water wall 1 be made up of cold wall pipe 6 and water screen tube fin 7 and partition wall water-cooling wall 2 arranges T-shaped seal 3.T-shaped seal 3 seals 4 by sealing fin A5A, sealing fin B5B, sealing fin C5C and semi arch and forms, one end of sealing fin A5A and sealing fin B5B is connected to the two ends of semi arch sealing 4, and one end of sealing fin C5C is connected to top in the middle part of semi arch sealing 4; Sealing fin A, sealing fin B are connected with the water screen tube 6 of side water wall 1 or partition wall water-cooling wall 2 respectively with the other end of sealing fin C; Angle between sealing fin A5A and sealing fin C5C is 90 °, and the angle between sealing fin B5B and sealing fin C5C is 90 °.
The diameter of semi arch sealing 4 is 42mm, and with the equal diameters of water screen tube 6, equal diameter can ensure that fume side heating surface is in form consistent in boiler water wall, avoids disturbance flow field, is also convenient to outside insulation etc. simultaneously.The width L3 of the width L1 of sealing fin A5A, the width L4 of sealing fin B5B, sealing sealing fin C5C is 15mm, and be less than the width L1 of water screen tube fin 7, L1 is 40mm.The width of sealing fin is less than the fin width of water screen tube, mainly consider that semi arch sealing and sealing fin are equivalent to a heat transfer fin of T-shaped junction water screen tube on the whole, if overall width is excessive, the temperature at semi arch sealing middle part will be caused too high, metallic high temperature may be caused to be oxidized.
All connections between semi arch sealing 4, sealing fin A5A, sealing fin B5B, sealing fin C5C, water screen tube 6, water screen tube fin 7 all adopt welding manner.
When boiler startup or blowing out, due to the change of temperature, side water wall 1 and partition wall water-cooling wall 2 can produce the displacement of horizontal direction in various degree, if this displacement is different, just must be absorbed by seal.The semi arch sealing 4 of T-shaped seal 3 is a semicircle, by being out of shape the displacement that can absorb all around.The arc lateral surface of semi arch sealing 4, in stove, does not disturb the flow field in stove, and sealing property is all good with absorption expansion character.
