Description
Technical field
The utility model relates to a kind of exchange type long lifetime high-temp mixing valve, is applicable to the sulphur recovery equipment of industries such as oil refinery, natural gas processing plant, gas-tank factory.
Background technique
At present, in the oil refinery sulfur recovery facility, for abundant condensation solid sulfur, generally with sulfurous gas with condenser condenses to low temperature (160～1800 ℃), and the low temperature sulfurous gas is to guarantee reactivity and reaction velocity when entering downstream sulfur reaction device, requires its temperature in 220～2400 ℃ scope, like this, just must be to low temperature sulfurous gas heat temperature raising.Oil refinery generally is the high-temp mixing valve (abbreviating mixing valve as) that adopts three-port structure, and the high-temperature gas that low temperature sulfurous gas and acid combustion furnace are produced is provided with obconic high-temp mixing valve valve head by the outlet port of high temperature pipe, forms circulation between the two and encircles.Drive the valve head lifting by valve rod, the area of circulation ring is changed, thereby change the flow of high-temperature gas.Acid valve rod drives the valve head lifting, and the area of circulation ring is changed, thereby changes the flow of high-temperature gas.The hot-gas temperature that acid combustion furnace produces up to 13000 ℃ about, and contain poisonous, corrosive materials such as H2S, SO2.
Such mixing valve type is as follows both at home and abroad at present: German LURGI valve core material adopts nonmetallic material or metallic material, and the spool head is parabola shaped structure; The spool head of France MG company is the bowl shaped structure that steel plate bends; The spool of Canada WYTON company is a plate-like structure, is lined with nonmetallic material below the flat board, and this kind structure is regulated poor sensitivity.The spool of domestic production is solid segment shape structure, all can not reach long-term work under the 1200-1400 ℃ of high temperature requirement, can not effectively lower the temperature, be not easy to regulate the high-temperature gas flow.The mixing valve that generally use in present domestic production field mainly contains following four kinds of forms:
1, no condiment protective gear, hot-fluid directly acts on filler, and filler is easily dry, leak outside.
2, spool adopts high-temperature alloy steel (about 800 ℃ of the highest adaptive temperature of high-temperature alloy steel in the market), and life cycle 3-6 month, the control sensitivity error was 8-12 ℃.
3, the spool high-temperature alloy steel adds surface lining corundum, because the corundum that serves as a contrast easily comes off, difficult quality is stable, life cycle 3-8 month.
4, adopt cooling water that spool is cooled off, because temperature is too high in the valve body, water is vaporized once entering, and is difficult to deliver to the spool position, and owing to add external medium, there is potential safety hazard in the valve of this kind form.
The model utility content
The technical problem that the utility model solved provides and a kind ofly anti-leaks outside, high temperature resistant, regulate highly sensitive, can effectively reduce the spool temperature and make the exchange type long lifetime high-temp mixing valve of producing the purpose that continous-stable carries out to reach.
For solving above-mentioned technical problem, the technological scheme that the utility model is taked:
The utility model comprises spool, valve rod, auto-manual hydraulic actuator, its special way is: described spool is formed the integral type spool by heat exchanger, spool conical surface, spool parabola face, spool parabola face is arranged on the outlet of valve seat, its opposite side connects the spool conical surface, and the right side of spool conical surface connects heat exchanger.
One side of above-mentioned heat exchanger is provided with radiation proof board, and fixes by the twin-lock jack panel.
The outlet of above-mentioned valve seat is a conical outlet, and the angle of taper of the spool conical surface of its angle of taper and spool cooperates.
Compared with prior art, the beneficial effects of the utility model:
The utility model can effectively prolong the service time of spool, improve and regulate sensitivity, thereby improve the continous-stable of producing, it is short fundamentally to have stopped present high-temp mixing valve life cycle, regulate poor sensitivity, and cause up-stream system to be forced to stop owing to stop, make some hazardous mediums to discharge, be forced to the potential safety hazard of emptying burning.
The utility model is provided with radiation proof board, has effectively protected filler, in case leak outside; Designed the heat exchanger spool, utilized in the system medium spool effectively to be lowered the temperature by heat exchanger; The heat exchanger spool is heat exchanger and spool integral structure, and heat-conductive characteristic is good; Spool is that conical surface connects parabola face dual regulating forms, has reduced the barbecue of hot-fluid to spool, washes away, and corrodes and has improved conciliation sensitivity; The heat exchanger spool can be by increasing, the heat diffusion area of reduction of heat exchanger, and temperature 300-500 ℃ of reducing spool worked spool in 700-900 ℃ environment; With the outlet of valve seat is conical outlet, makes hot-fluid be dispersed evenly to spool face with the umbrella shape shape, and reduction spool part is impaired.
The utility model is applicable to recovery technology of sulfur, can effectively improve the working life of valve, reach the realization system continuously, the purpose of steady production, also can be used for control, the adjusting of the pipe-line system of other high-temperature operations.
