Description
Technical field
The utility model relates to the sealing between a kind of water-cooling wall, relates in particular to the seal that the T-shaped docking of a kind of water-cooling wall connects, and belongs 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, pipe and fin, consists of.Connection between water-cooling wall and water-cooling wall relates to thermal expansion problem, if solve bad, boiler is in the processes such as startup, blowing out, because thermal stress will be drawn bad water screen tube, particularly in T-shaped seam and the easier drawing crack of water screen tube that is connected part of side water wall and partition wall water-cooling wall.Chinese patent ZL 97 1 03977.1 has announced a kind of incinerator, Chinese patent CN200510126362.6 has announced a kind of Horizontal type circulating fluid bed combustion apparatus and circulating combustion method thereof, in these boilers, all run into the problem that side water wall is connected with partition wall water-cooling wall, and in actual motion, also all occurred the drawing crack problem that water-cooling wall thermal stress causes.For the sealing problem connecting between water-cooling wall, importantly to solve thermal expansion problem, namely sealing device is except guaranteeing that, sealing, also wanting can absorbing thermal expansion.Chinese patent CN 201715483 U disclose the seal at a kind of boiler tube place, adopt seal box and a plurality of straight connector to carry out, but are not suitable for the elastic packing between water screen tube.Chinese patent CN 202092106 U disclose the sealing mechanism between a kind of furnace arch, furnace nose and rear wall cigarette well front wall, utilize flanged plate sealing and absorb 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 purpose of this utility model is to provide the seal of a kind of simple in structure, sealing property between being connected with the good T-shaped water-cooling wall of absorbing thermal expansion performance.
The utility model is achieved through the following technical solutions:
Seal between a kind of T-shaped water-cooling wall, be arranged in the side water wall that formed by cold wall pipe and water screen tube fin and the T connector place between partition wall water-cooling wall, 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 L4 of the width L1 of sealing fin A, sealing fin B, sealing sealing fin C equates, and be all less than the width L1 of water screen tube fin, i.e. L2=L3=L4<L1.Semi arch seals, seals between fin A, sealing fin B, sealing fin C, water screen tube, water screen tube fin by being weldingly connected.
The utility model 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. be easy to keep the rigidity of water-cooling wall.
Accompanying drawing explanation
Fig. 1 is the T-shaped connection diagram of the related water-cooling wall of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram;
Fig. 3 is the seal schematic diagram between the related a kind of T-shaped water-cooling wall of the utility model.
In figure: 1-side water wall; 2-partition wall water-cooling wall; 3-T type seal; The sealing of 4-semi arch; 5-seals fin; 6-water screen tube; 7-water screen tube fin.
The specific embodiment
Below in conjunction with accompanying drawing, describe concrete structure of the present utility model, operation principle and embodiment in detail:
Fig. 1 is the T-shaped connection diagram of the related water-cooling wall of the utility model, and the A-A that Fig. 2 is Fig. 1 is to schematic diagram, and Fig. 3 is the seal schematic diagram between the related a kind of T-shaped water-cooling wall of the utility model.At the side water wall 1 being formed by cold wall pipe 6 and water screen tube fin 7 and the T connector place between partition wall water-cooling wall 2, arrange T-shaped seal 3.T-shaped seal 3 is comprised of sealing fin A 5A, sealing fin B 5B, sealing fin C 5C and semi arch sealing 4, one end of sealing fin A 5A and sealing fin B 5B is connected to the two ends of semi arch sealing 4, and one end of sealing fin C 5C is connected to semi arch and seals 4 tops, middle part; 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 A 5A and sealing fin C 5C is 90 °, and the angle between sealing fin B 5B and sealing fin C 5C is 90 °.
The diameter of semi arch sealing 4 is 42mm, and with the equal diameters of water screen tube 6, equal diameter can guarantee 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 L4 of the width L1 of sealing fin A 5A, sealing fin B 5B, sealing sealing fin C 5C is 15mm, is less than the width L1 of water screen tube fin 7, and L1 is 40mm.The width of sealing fin is less than the fin width of water screen tube, mainly to 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 excess Temperature that will cause semi arch sealing middle part, may cause metallic high temperature oxidation.
All connections between semi arch sealing 4, sealing fin A 5A, sealing fin B 5B, sealing fin C 5C, water screen tube 6, water screen tube fin 7 all adopt welding manner.
When boiler startup or blowing out, due to the variation 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 distortion, can absorb displacement all around.The arc lateral surface of semi arch sealing 4, in stove, does not disturb the flow field in stove, and sealing property and absorption expansion character are all good.
