Application number is that 200420079504.9 utility models disclose a kind of heat pipe self ash-cleaning type sampling probe.By finding this probe owing to need to increase a high-pressure cylinder to researching and analysing, the scene need provide a cover gaseous tension device separately, because site work environment is abominable, the expanding-contracting action time that adds casing top half, so be easy to make cylinder falling into owing to particles such as dust, brought hidden danger for the smooth and easy action of cylinder, thereby brought trouble for installation and correction maintenance, simultaneously because this device also needs to provide the cooling medium of distilled water as cool cycles, the scene need provide a water tank device, and this has brought trouble also for the installation of system; Because this device adopts common metal pipe material, so during the unexpected lack of water of the chilled water in the system, if untimely the releasing of probe can be easy to be burnt out, and this probe can only be used for own company used product, do not have versatility, be not suitable for to the same industry as popularization.
Summary of the invention
The object of the invention is to provide a kind of does not have the motion device, need not to provide the sampling probe of pressurized air and water tank dismounting extracting high-temperature sample gas continuously, and this probe can also exchange with the sampling probe in the existing high temperature sample analysis system.
The present invention discloses a kind of sampling probe of extracting high-temperature sample gas continuously, it is characterized in that: comprise the shell supporter, shell supporter one end is equipped with the stainless steel mounting flange, other one section is provided with the import of sample gas, the embedded cool cycles pipeline of shell supporter, cool cycles pipe water mouth is provided with the water filter and first manual ball valve, water delivering orifice is provided with the power-adjustable suction pump, stopple coupon is installed in the shell supporter by the stainless steel mounting flange, and link to each other with the import of sample gas, and form seal cavity between stopple coupon and the shell supporter.Described shell supporter is to adopt high temperature resistant cement and high temperature resistant hollow ceramic microspheres to mix according to 2: 1～5: 1 volume ratio, and utilizes high temperature resistant binder to make.
Above-mentioned stopple coupon can adopt the composite ceramic material with inoxidizability, heat-resisting quantity to form by 1000 degree high-temperature firings.
Sampling probe links to each other with user's filter collector, sample letter shoot by mounting flange the sample pneumatic transmission is gone into analytic system analysis.This sampling probe is because the external support body uses high temperature resistant cement and high temperature resistant hollow ceramic microspheres to be mixed and made into, because high temperature resistant cement has good plasticity and heat-resisting quantity, the heat-resisting quantity of hollow ceramic microspheres is eager to excel than the heat-resisting quantity of cement simultaneously, both mix according to 2: 1～5: 1 ratio of volume ratio can play the heat insulation effect of good heat-resistance, thereby has guaranteed the stability of high temperature resistant system.Inner cooling duct adopts plating crystal silicon stainless steel waterpipe, owing to adopt the pipeline of this material can guarantee that long use can be owing to water temperature produces incrustation scale, thereby can well play the effect of insulation, inner sampling pipe has adopted high temperature resistant composite ceramic pipe can stablize, efficiently the sample pneumatic transmission be gone out.The composite ceramic pipe has good oxidative resistance, also has fine compactness simultaneously, thereby has guaranteed entering of non-sample pneumatolytic branch, thereby guarantees the authenticity of sample gas.Selection by above material can be so that the high temperature sampling probe have satisfied no motion device, need not to provide pressurized air and distilled water to be convenient to installing/dismounting, to exchange with sampling probe in the existing high temperature sample analysis system.
The advantage of device disclosed by the invention is described below:
(1) authenticity.Because the composite ceramic characteristics of molecular structure makes it have good insulation performance and chemical stability (particularly inoxidizability), so be highly suitable for such as the such high-temperature systems of cement furnace.
(2) saving property and nonstaining property.Directly adopt industrial colling to carry out cool cycles, can reach the purpose of conserve water resource, but it can not produce other pollutant simultaneously, thereby reach the purpose of nonstaining property;
(3) heat-resisting quantity.Because high-temperature cement has fine plasticity and heat-resisting quantity, and hollow ceramic microspheres has absolute heat-resisting quantity, so both can improve the heat-resisting quantity of system with a certain proportion of combination;
