Description
Technical field
The present invention relates to boiler internal workpiece technical field, more particularly to a kind of self-sealed economizer of pluggable fast-assembling.
Background technology
Economizer is as one of important heat transfer component of boiler, and it utilizes the heat boiler of the tail flue gas of boiler
Feedwater, and then reduction exhaust gas temperature can be reached, improve the effect of boiler efficiency.Because the part belongs to pressure-containing member, it is made
Make and installation quality directly affects efficient, the safe operation of boiler.
Common economizer has two kinds of steel pipe type and cast iron type, and steel pipe type is exactly to use one or more groups of coiled pipe and collection
Case is constituted, and outside is sealed using steelframe, backplate, furnace wall, most in-site installation；It is substantially all for cast iron gilled tube economizer
In-site installation, pipe and the live bolt connection of elbow.
Economizer is located in boiler back end ductwork, either steel tube economizer or cast iron gilled tube economizer, and its sealing property is outstanding
To be important.
Steel tube economizer is general to be sealed on the crossbeam of steelframe using steel guard board structure, the crossbeam and column of steelframe
Between have certain gap, it is difficult to thoroughly be eliminated in the later stage, be easily caused air leakage into flue duct.Other majority coiled pipes, backplate, steelframe
All it is in-site installation, workload is big, easily causes mass defect.
The content of the invention
Weak point present in regarding to the issue above, the present invention provides a kind of pluggable self-sealed economizer of fast-assembling.
To achieve the above object, the present invention provides a kind of pluggable self-sealed economizer of fast-assembling,
At least connected by two structure identical economizer units with overlying relation or left-right relation link is formed；
The economizer unit includes four blocks of sealing steel plates, wherein the sealing steel plate is symmetrical arranged two-by-two, in four pieces of institutes
State and column is installed with the outside of sealing steel plate, four pieces of sealing steel plate lower insides are provided with support beam；
Coiled pipe, it is arranged on inside four blocks of sealing steel plates, and one end of the coiled pipe is located at the sealing steel plate
Outer upper and header welding, the other end of the coiled pipe is located at the sealing steel plate outer lower portion and the coiled pipe of lower section connects
Connect.
Further improved as of the invention, be fixed with pipe clamp in the support beam, the pipe clamp is stuck on the coiled pipe.
Further improved as of the invention, the coiled pipe is single tube in-line structure or multitube shifted structure.
Further improved as of the invention, the sealing steel plate is fitted seal above and below primary and secondary slot structure.
Further improved as of the invention, heat-insulation layer is enclosed with the outside of the sealing steel plate.
As currently preferred, the heat-insulation layer is alumina silicate fiber felt material.
Further improved as of the invention, the column of the column and lower section is fixed or bolt connection by alignment pin.
Further improved as of the invention, the coiled pipe is connected with the coiled pipe by header or pipeline.
Beneficial effects of the present invention are：At least it is made up of economizer unit more than two；Economizer unit is using snakelike
Tubular construction, can be single tube in-line, it would however also be possible to employ multitube shifted structure；Scene seals dense steel plate using pluggable mother-son groove
Envelope, installs simple, convenient disassembly, sealing property excellent；It is fast using some alignment pins (bolt) inside two groups of economizer units
Speed is fixed；Weld and complete in economizer unit factory, the quick assembling in scene.
