Description
Technical field
The present invention relates to a kind of heat accumulating type heating system, particularly a kind ofly provide HTHP pure air and the heat accumulating type heating system of anti-slag-falling.
Background technology
In order to carry out the experimental study of supersonic combustion on ground, the ground-based simulation equipment of oxygen components in the enthalpy of energy simulated flight state, speed and gas need be built.The mode of heating with this analog capability has multiple, and the large discharge gas-heated mode adopted both at home and abroad at present is mainly divided three classes: (1) electric arc heated: the air-flow making to flow through electric arc by HVDC arc discharge is heated; (2) combustion heating: by feeding the fuel such as hydrogen, utilize partial air to realize combustion heating air-flow as oxidant; (3) accumulation of heat heating: utilize the energy heats air-flow be stored in advance in high-temperature heat accumulation material.
Electric arc heated mode can obtain very high heating-up temperature (3000-10000K), but the generation of oxynitrides and the problem such as electrode erosion pollutant and efficiency loss make such heater be difficult to really reappear real features heat, the chemical environment of hypersonic aircraft.Combustion heating mode can obtain higher gas flow temperature.But experiment and numerical simulation all find, combustion heating mode can produce free radical, still there is air-flow chemical constituent and the differentiated problem of real air of acquisition.When chemical constituent departs from, the physical characteristic of air, such as can there is marked change in specific heat etc., affects experimental precision.
Combustion heating mode has good economy performance, and structure is simple, and the feature that efficiency is high is most widely used general.But there is the pollution components different from air in test gas after combustion heating.When using hydrogen fuel to add hot-air, pollution components mainly H2O and free radical at high operating temperatures, and when using hydrocarbon fuel to add hot-air, pollution components mainly H2O, CO2 and free radical; Pollution components makes cannot gas incoming flow completely under Reality simulation flight condition by the high-temperature gas that heats, causes the extension tested from ground experiment to engine flight to exist uncertain.
Heat energy is stored in heat-storing material with slower speed by electrical heating or combustion heating process by heat accumulating type heating, and when wind tunnel operation, heat energy passes to air with very high speed again.This kind of mode of heating can obtain chemical constituent and the on all four flow conditions of real air.When testing for scramjet engine ground performance, heat accumulating type heating obtains the highest one of data reliability in three kinds of mode of heatings.
Strictly speaking, the high temperature air after heat accumulating type heating is not 100% pure, is generally all mingled with solid dust, and these solid dusts repeatedly wash away because heat-storing material and furnace lining material are subject to air-flow and come off.These solid dusts can affect reliability and the authenticity of ground experiment, in order to obtain more reliable test data, are necessary that the solid dust to being mingled with in gas processes.
Cyclone separator has simple structure and the advantage such as cheap, and operation pressure drop is medium, if reasonable employment, can not break down for a long time.Particle diameter is greater than to the separation of 5 micron dusts, its separative efficiency is good.Cyclone separator is commonly used for last separator in big dust particle separation process, also can be used as efficient cyclone.
And namely anti-slag-falling HTHP regenerative pure air heating system of the present invention is the cyclone separator adding band water-cooling structure on the basis of heat accumulating type heating system, carry out dedusting to the high temperature and high pressure gas of accumulator outlet, this cover separator system has good separation property to dust particle diameter being greater than to 5 microns.
