Abstract
The utility model relates to a component of a laser Raman spectrum device, providing a sample pond for gas-liquid phase high temperature pressure-resistance original position laser spectrum, comprising a sample tube, an electric heating element, a thermocouple, a metal outer cover with a light passing hole, ingress and egress air tubes, a sample disc, a soleplate, a base and a fastening fitting. A sample cover is arranged between the electric heating element and the sample tube, a thermocouple hole is arranged on the top of the sample cover, the sample disc is arranged on the side of the thermocouple hole, and the cooling and flow system of closed water such as a cooling water jacket, etc. is also arranged. The utility model is adapted to the particular requirements of high temperature and pressure resistance, a Raman spectrometer and accessories can be prevented from damaging by heat wave, high-temperature resistance can reach about 700 DEG C, and pressure resistance is about 1.5 MPa.
Description
The utility model relates to a kind of parts of laser Raman spectrum device.
The design people proposes a kind of boiling type in situ laser Raman spectrum specimen pool in the CN91105112.0 patented claim, it comprises sample hose, microporosity separator, heating, thermopair and has the parts such as metal cap of light hole, be connected with upper end cap and pedestal by O-ring seal, pressure ring, fastening nut, heating and thermopair place the sample hose two ends respectively, and microporosity separator places the top of heating.This sample cell can not only reduce laser beam heat to greatest extent, and luminous effect is decomposed destruction to sample and attachment thereof, improves the detection sensitivity of laser Raman spectrum significantly.But it can not be high temperature resistant, can not stand too high pressure.
The purpose of this utility model aims to provide a kind of improved sample cell that is applicable to gas-solid phase high-temperature pressure-proof original position laser Raman spectrum test.
Gas-solid phase high-temperature pressure-proof original position laser Raman spectrum specimen pool comprises metal housing, draft tube, escape pipe, sample disc and base plate, top base, bottom base and the fastening accessory of sample hose, heating, thermopair, band light hole.The sample cover is arranged between heating and sample hose, and the thermocouple hole of placing thermopair is established on sample cover top, and sample disc is located at the side of thermocouple hole.Between metal housing and upper and lower pedestal, establish upper and lower cooling water jecket, water inlet pipe and external water pipe joint are arranged on the following cooling water jecket, rising pipe and external water pipe joint are arranged on the last cooling water jecket.
At the topped heat-insulation layer of metal housing inwall.In fact above-mentioned measure combines heating, sample cover, sample disc and thermocouple hole together and constitutes sample cover-electric heater assembly, sheet or pulverized specimen place sample disc, thermocouple hole near sample disc is used to place thermopair, the topped heat-insulation layer of metal housing inwall.Like this, adapted to the special requirement of high temperature resistant (about 700 ℃) and anti-certain pressure (about 1.5MPa).Being provided with of cooling water jecket and accessory thereof will prevent that heat wave from damaging Raman's spectrometer and annex.
Accompanying drawing is gas-solid phase high-temperature pressure-proof original position laser Raman spectrum specimen pool structural drawing.
Embodiment: as shown in drawings, sample cell comprises metal housing (26), draft tube (31), escape pipe (19), sample disc (12), base plate (1), top base (upper end cap) (15), bottom base (2) and the fastening accessory of sample hose (10), heating (9), thermopair (13), band light hole (11), for example tightens up screw (3,18), O-ring seal (5,6,16,23,27,28) and pressure ring (4,7,17,22,29) etc.Sample cover (25) is arranged between heating and the sample hose, and the thermocouple hole (24) of placing thermopair is established on sample cover top, and there is sample disc (12) side of thermocouple hole.Between metal housing and upper and lower pedestal, establish upper and lower cooling water jecket (14,8), water inlet pipe (32) and external water pipe joint (35) are arranged on the following cooling water jecket, rising pipe (33) and external water pipe joint (34) are arranged on the last cooling water jecket, but form the airtight current system of an outer cover water flowing cooling.
Sample hose is a transparent quartz tube.The topped heat-insulation layer of metal housing inwall.
The flow process of said apparatus is: sheet or pulverized specimen are placed sample disc, and unstripped gas imports from air intake opening, and temperature of reaction is by thermocouple measurement and control.Reaction product is derived by escape pipe.
