Background technology
Parts inwalls in operational process such as Utility Boiler Superheater, reheater, jet chimney are corroded by steam oxidation can, in order to study its oxidizing process and mechanism, units concerned have developed the steam oxidation test unit, simulation test is carried out in realization in the laboratory, such as, patent of invention CN101118211B " high-temperature steam oxidation test device " and patent of invention CN10162661 B " metal material high temperature water vapor oxidation experiment device ".These two patents of invention provide the solution in normal pressure or the test of low-voltage high-temperature steam oxidation.In fact, the vapor pressure of now widely used super (super-) critical boiler can reach 24～28MPa, and the physicochemical property of this supercriticality water and high-temperature steam have very big-difference.For the steam oxidation agreement with experimental actual conditions that the laboratory is carried out, need to improve the pressure of water vapour, key issue is to need to bear 30MPa pressure and 700 ℃ of temperature or the reaction vessel of elevated steam conditions more, and employing heat-resisting steel or high temperature alloy forging are made the reactor difficulty greatly and are involved great expense, and operation and maintenance is also inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of more easy reliable supercritical water steam oxidation test reaction vessel.
In order to achieve the above object, the technical solution of the utility model has provided a kind of supercritical water steam oxidation test reaction vessel, it is characterized in that: comprise tubular reactor vessel, end at tubular reactor vessel is provided with flange, the other end is provided with end cap, the inner chamber of interpolation pipe inserting pipe-type reaction vessel.
Preferably, described tubular reactor vessel is the metal tube that heat-resisting steel or high temperature alloy are made, and this metal tube external diameter is 50～70mm, and wall thickness is 10～15mm.
Preferably, the length of described tubular reactor vessel is 1200～1500mm, is divided into preheating section and soaking zone, and sample places the soaking zone zone.
Preferably, described interpolation pipe for the substantially isometric bore of described tubular reactor vessel be heat-resisting steel or the high temperature alloy pipes of 6～10mm.
Preferably, the blind flange center that described interpolation pipe passes described flange insert described tubular reactor vessel inner chamber and with the blind flange welding, an end of described interpolation pipe inserts armoured thermocouple and enters its inner chamber, other end welding shutoff also is equipped with centring ring.
Preferably, around described interpolation pipe, be welded with for the pin that hangs sample, at interpolation pipe corresponding to the regional overcoat of the preheating section of described tubular reactor vessel by the flow-disturbing mechanism that is formed by throttle, be drilled with aperture at throttle, make the steam of flowing through evenly mixed.
The utility model selects metal tube as reaction vessel, manufacture difficulty and cost, and can directly place tubular heater heating and insulation, available soaking zone scope is large, guarantee enough test spaces, because internal diameter of the pipeline is less, be conducive to improve steam flow rate; The flange arrangement easy accessibility is adopted in the reaction vessel medium inlet; The reaction vessel interpolation pipe has three functions concurrently: the interpolation thermopair be used for to be measured vapor (steam) temperature, is burn-on that pin is used for hanging sample, preheating section is installed flow-disturbing mechanism makes the steam flow homogeneous heating all around.

Fig. 1 is according to the supercritical water steam oxidation test reaction vessel schematic diagram that the utility model proposes.
Wherein: 1-flange, 2-tubular reactor vessel, 3-interpolation pipe, 4-throttle, 5-pin, 6-centring ring, 7-end cap, 8-sample, 9-inner chamber thermopair.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, a kind of supercritical water steam oxidation test reaction vessel that the utility model provides adopts the metal tube of being made by heat-resisting steel or high temperature alloy as tubular reactor vessel 2, select external diameter 50～70mm, wall thickness 10～15mm, but long-time running is applicable to the pressure and temperature requirement of boiler steel steam oxidation experimental study fully in 30MPa/700 ℃ of steam condition; The length of this tubular reactor vessel 2 can be selected according to test condition, general optional 1200～1500mm, and along MEDIA FLOW to, its leading portion (being preheating section) is used for media preheating, back segment (being soaking zone) is used for insulation and the sample loading space is provided; The medium input end welding steel high pressure flange 1 of tubular reactor vessel 2 has the medium inlet on the blind flange of flange 1; Medium output terminal welding heat-resisting steel or the high temperature alloy end cap 7 processed of tubular reactor vessel 2 have media outlet on the end cap 7; (6～10mm) heat-resisting steel or high temperature alloy pipes pass the inner chamber of blind flange center inserting pipe-type reaction vessel 2 as interpolation pipe 3 and weld with blind flange with substantially isometric small-bore of tubular reactor vessel 2, interpolation pipe 3 one ends can insert armoured thermocouple and enter its inner chamber, other end welding shutoff also is equipped with centring ring 6, be welded with pin 5 around the part of interpolation pipe 3 corresponding tubular reactor vessel 2 sample areas and be used for hanging sample, corresponding to the nested domain of preheating section by the flow-disturbing mechanism that is formed by throttle 4, be drilled with aperture on the throttle 4, make the steam of flowing through evenly mixed.
During use, reaction vessel can be arranged vertically, also can be horizontally disposed, and generally be arranged vertically and be convenient to save lab space and sample is installed.Before on-test, sample 8 is fixed on the pin 5 of interpolation pipe 3, then puts tubular reactor vessel 2, last assembly flange 1.The reaction vessel assembly that assembles is connected to high pressure water loop, put tubular heater again and just can carry out the steam oxidation test: low temperature liquid water enters tubular reactor vessel 2 from flange 1, the preheating section temperature of flowing through constantly raises, and it is even by throttle 4 steam flow to be mixed, steam enters sample area after arriving test temperature, with sample generation oxidation reaction, discharged by end cap 7 outlets at last.The thermopair that interpolation pipe 3 inner chambers insert by the change insertion depth can monitoring reaction container diverse location temperature.Off-test reduces system temperature and pressure to safe range, pulls down the reaction vessel assembly from the loop, opens flange 1, removes tubular reactor vessel 2, gets final product sample analysis.
