Description
Technical field
This utility model relates to field of boilers, specifically a kind of compensator suitable in blast furnace gas boiler。
Background technology
Therrmodynamic system gas fired-boiler, is by the blast furnace gas produced in blast furnace ironmaking process of burning, provides steam power for steam turbine, be used for generating electricity or driving axial flow blower；Boiler coal gas system principle is: blast furnace gas cuts valve soon through coal gas, regulate valve flows to the high coal arm at one to five layer of four angle of boiler, enters hearth combustion after hand-operated valve, electrodynamic valve, metal hose；Before the burner of therrmodynamic system gas fired-boiler, what design used is the metal hose of 304 stainless steels, and medium is blast furnace gas；Containing higher chlorine ion concentration in the blast furnace gas of blast furnace ironmaking institute output, and the metal hose anti-chlorine ion corrosion of 304 stainless steels is not high；The installation length of metal hose is 1.2 meters simultaneously, what it adopted in processing technique is that two sections of corrugated tubes 0.6 meter long are assembled by the mode welded, middle this road weld seam additional is also susceptible to corrosion leakage, the situation of blast furnace gas metal hose seriously corroded before burner often occurs, leakage coal gas after causing equipment to use a period of time, for reducing maintenance number of times, guarantee safe operation of the boiler, it is necessary to slow down corrosion, improve the service life of flexible pipe。
Utility model content
The purpose of this utility model is in that to provide a kind of compensator suitable in blast furnace gas boiler, with the problem solving to propose in above-mentioned background technology。
For achieving the above object, this utility model provides following technical scheme:
A kind of compensator suitable in blast furnace gas boiler, including mounting flange, end pipe, lug, corrugated tube, intervalve and loose flange, the two ends of described intervalve are connected to end pipe respectively through corrugated tube, the end pipe of one end is provided with mounting flange, the end pipe of the other end is provided with loose flange；The inwall of described intervalve, corrugated tube and end pipe is provided with anticorrosive coat；Being provided with lug on described end pipe and intervalve, be provided with pull bar between two lugs on adjacent end pipe and intervalve, pull bar is fixed on lug by nut。
As further program of the utility model: described corrugated tube is 254Smo stainless steel tube。
As this utility model further scheme: described anticorrosive coat is polyurea coating。
Compared with prior art, the beneficial effects of the utility model are: this utility model by replacing to freely compound type compensator by 304 flange-connection stainless steel metal flexible pipes of the prior art, adopt end pipe, the combining form of corrugated tube and intervalve, 254Smo stainless steel tube selected by corrugated tube, and at end pipe, corrugated tube and intervalve inwall arrange polyurea coating and improve its antisepsis, effectively prevent in therrmodynamic system gas fired-boiler burner in use for some time, metal hose seriously corroded, the problem that there is gas leak, compensator of the present utility model can improve equipment service life, slow down corrosive pipeline, reduce maintenance maintenance expense, guarantee the safe operation of boiler。
