Description
Technical field
The present invention relates to the flue gas turbine expander of oil refining, chemical industry, energy saving, particularly relate to a kind of inner stator blade flue gas turbine expander.
Background technique
Flue gas turbine expander utilizes catalytic regenerator to burn the heat energy of produced high-temperature low-pressure flue gas and the rotating machinery of pressure energy work done, and the mechanical energy utilizing cigarette machine to produce drives the equipment work such as main air blower or generator or generating, reaches the object of recovered energy.Domestic now operation flue gas turbine expander about 220, wherein about 85% is the YL type series adopting Lan Lian machinery plant to produce, and is axial admission, the radial cantilevered support structure be vented, point single-stage and twin-stage two kinds; Residue is mainly Xi'an aeroengine Group Co., Ltd and German GHH company produces.
China's catalysis Energy Recovery Technology exploitation main process:
Within 1974, Lanzhou machinery plant sets up problem tackling key problem group together with Beijing designing institute, Engineering Thermophysics Suo Deng unit of the Chinese Academy of Sciences, has manufactured experimently China's First flue gas turbine expander in 1976, i.e. First YL series flue gas turbine expander.
Within 1978, China's first set catalysis energy-recuperation system builds up at Fushun second branch factory of oil, and the YL3000 type flue gas turbine expander of this factory trial-production once puts into operation successfully, has filled up domestic blank.So far, China has caught up with the developing steps of International Energy recovery technology.
2003, be put into the high-power flue gas turbine expander of 33000 kilowatt of " 15 " national major technologies and equipment development project, through sincerely uniting and the cooperation of Lanzhou machinery plant and internal class scientific research institutions, last nearly 3 years, finally succeed in developing.This is domestic First superpower flue gas turbine expander, and Ye Shi world Shou Tai is applied to the superpower flue gas turbine expander of high altitude localities.The development success of this flue gas turbine expander, make China after the U.S., become second country that can manufacture 30000 multikilowatt superpower flue gas turbine expanders in the world, this machine is one of only several more than 30,000 kilowatts flue gas turbine expanders in the world, that succeeds in developing is significant, is the important symbol that China's cigarette machine designed capacity and manufacturing capacity reach world-class levels.
Because the reasons such as original design technological means falls behind and the later stage does not have technological improvement, fast-growth cause existing operation flue gas turbine expander partial structurtes, design falls behind, and there is following problem:
1, domestic flue gas turbine expander stator blade is all non-adjustable;
2, all can there is larger fluctuation in domestic most refinery catalytic cracking device parameter in each season, not inner stator blade cause partial fume lose or efficiency too low;
3, domestic most refinery is due to market, the reasons such as material supply, and different time processing amount all can be inconsistent, and larger fluctuation can occur parameter, not inner stator blade cause partial fume to lose or efficiency too low;
4, the refinery catalytic cracking device of Some Domestic all increases treating capacity (expanding energy), and not inner stator blade causes partial fume to lose from double slide valve;
5, the component such as blade, wheel disc wash away seriously: because pneumatic design is unreasonable, and internal turbulence is serious, and a large amount of component run less than just scrapping the projected life of part, cause a large amount of economic loss;
6, fouling of catalyst is serious: because pneumatic design is unreasonable, internal turbulence is serious, and the reasons such as catalyst powder dust concentration contained by flue gas is high, particle is thin cause a large amount of catalyzer to pile up in runner, affect rotor dynamic balancing, cause the equipment operation period not long, nonscheduled down time is long;
The present invention intends carrying out structural design to flue gas turbine expander stator blade mechanism, proposes a kind of inner stator blade flue gas turbine expander, stator blade is designed to adjustable angle, contributes to solving the problem.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of inner stator blade flue gas turbine expander, arranges inner stator blade, stator blade is designed to adjustable angle.
The present invention solves the problems of the technologies described above the technological scheme adopted to be to provide a kind of inner stator blade flue gas turbine expander, comprise inlet casing, the side of described inlet casing is suction port, the upside of described inlet casing is relief opening, and arrange rotor assembly in described inlet casing, described rotor assembly comprises main shaft, moving vane, bearing, described bearing place arranges gland seal system, the inside of described suction port arranges inner stator blade, and wherein, described inner stator blade is set to adjustable angle.The upside of described moving vane arranges moving blade ' s shroud band, and described gland seal system comprises diaphragm seal and interdigitated electrode structure sealing gland.
The present invention has following beneficial effect relative to prior art:
Inner stator blade flue gas turbine expander provided by the invention, to flue gas turbine expander stator blade, mechanism carries out structural design, stator blade is designed to adjustable angle, contribute to solving expand can, process throughput change, the energy loss that causes of seasonal variations, solve flue gas turbine expander seasonal variations and cause the problem that Parameters variation behind efficiency is not high; Solve treating capacity change and cause the problem that Parameters variation behind efficiency is not high; After solving device expansion energy, the problem that parameter is not mated with flue gas turbine expander, efficiency is not high; Solve double slide valve aperture large, waste serious problem; In addition, contribute to alleviating catalyzer scale velocity on stator blade.
