Description
Technical field
The utility model relates to a kind of high-temperature high-pressure in-situ sampler, particularly relates to a kind of built-in in-situ sampling device that is applicable to high-temperature high-pressure reaction kettle, belongs to reactor sampler field.
Background technology
High-temperature high-pressure reaction kettle is a kind of common high temperature and high voltage experimental device, be widely used in earth interior high-temperature high pressure water fluid properties and the interaction of aqueous fluid-solid-phase, nuclear power station Supercritical-Pressure Light Water Cooled Reactor, and the High Temperature High Pressure simulated experiment of chemical research field, be also simultaneously a kind of in the industrial circles such as petrochemical complex, coal-fired clean utilization and artificial lens cultivation common production equipment, its feature is to provide a kind of reaction environment of High Temperature High Pressure.In order to detect the carrying out of chemical reaction in autoclave, must to the high-temperature, high pressure fluid in autoclave, sample to vouch chemical composition.Yet because high temperature and high pressure environment is extremely harsh, efficient, precisely reliable in-situ sampling technology is the important goal of high temperature and pressure experiment technical development always.
At present, the high-temperature high-pressure in-situ sampling technique of having invented mainly comprises in-situ sampling valve technology, built-in needle-valve sealed sampler technology and manual parcel body sampling technique: (1) in-situ sampling valve technology is to use a capillary, one end is communicated with the sample chamber of high temperature pressure vessel, the other end is positioned at normal temperature and pressure district and is communicated with sampler, in centre capillaceous, one high pressure valve is installed by cold-zone, valve before sampling in closed condition.When experiment proceeds to set condition, open valve, the fluid sample in high temperature pressure vessel sample chamber flows out and enters sampler from kapillary, thereby obtains the fluid sample in sample system under High Temperature High Pressure.This in-situ sampling valve technology is widely used in high-temperature high-pressure reaction kettle at present; but in this technology; sampling process is actually the process that sample temperature pressure falls suddenly; for be conventionally dissolved with the fluid of a large amount of solid matters under High Temperature High Pressure; when temperature, pressure declines suddenly, often have surface in contact and the inwall capillaceous of dead space, valve and fluid that solid matter is precipitated to valve from fluid, thereby cause the quality of fluid sample in sampler to lose.(2) built-in needle-valve sealed sampler technology, is similar to high pressure valve is positioned over to autoclave inner sealing and catches fluid, this technology basic building block comprise built-in sampling container, valve rod, needle-valve and seal.Wherein, built-in sampling container is that one end is uncovered, surfaces externally and internally is through the titanium alloy canister of passivation, and it is radially adjustable with axial locus in cylindric still chamber; Valve rod is that a surface is made coniform and the uncovered inner edge of sampler and jointly formed needle-valve mechanism through titanium alloy Metallic rod ，Qi one end of passivation, and the other end is positioned at the normal temperature and pressure district beyond high temperature pressure vessel, and the seal that is positioned at High Temperature High Pressure district is run through in intermediate portion; Seal graphite high temperature resistant, yielding by tool and the sliding effect of tool increasing is made.In high temperature and pressure experiment, cylindric high temperature pressure vessel is erect vertically, is positioned at the valve rod of normal temperature nip by rotation, can realize the original position sealing of sample in sampler.This built-in needle-valve sealed sampler technology is mainly used in learning high temperature and pressure experiment, but this technology also exists some problems in application: graphite seal cannot be avoided and fluid contact, thereby can cause sample contamination to a certain degree; Valve rod in this technology and the sealing between seal belong to heat seal, and the rotation of valve rod need overcome the friction between High Temperature High Pressure district valve rod and seal, and valve rod limited intensity at high temperature can exert an influence to the serviceability temperature of this technology and pressure undoubtedly.(3) manual parcel body in-situ sampling technology, in its principle Shi sample chamber, place the transparent mineral containing micro-flaw (conventionally being produced by thermal shock), the residing environmental communication of the micro-crack in transparent mineral and mineral wherein, in high temperature and pressure experiment process, in fluid, there is dissolve-repreparation process in transparent mineral, thereby make micro-flaw that sealing occur and form inclusion one by one, now the fluid in sample system is wrapped body original position and forms and nondestructively seal up for safekeeping.This technology can be widely used in the high temperature and high voltage experimental devices such as autoclave, flow reactor, piston cylinder and the large cavity of polyhedron, but people are in long-term practice, find that this technology exists following drawback: this technology is only applicable to sample system itself and contains the situation of the carrier mineral of manual parcel body, otherwise can be due to the contaminated samples that adds of carrier mineral; Because inclusion sealing needs the crystalline growth of experience long period, just can complete, so this technology almost can not be for being intended to carry out the high temperature and pressure experiment of dynamics research; For dynamic process high temperature and pressure experiment comparatively slowly, thereby difference off-period due to different inclusions can cause the fluid composition that different inclusions is captured there are differences, so this technology is not suitable for dynamic process high temperature and pressure experiment slowly yet.
In sum, in-situ sampling technology has extreme importance for the high temperature and pressure experiment containing fluid heterogeneous system, yet currently used various in-situ sampling technology is all difficult to reach quick, single-phase state and the harmless requirement of sample composition simultaneously, therefore develop a kind of quick, single-phase state and the harmless high-temperature high-pressure in-situ sampling technique of sample composition, become the current international difficult problem that need solve containing the heterogeneous substance system high temperature and pressure experiment of fluid research field.
