The sample measuring apparatus is a multiple reflection spectral measurement apparatus and comprises an optical element and an installation part thereof, a sample measuring cell and a heating device, wherein the heating device is used for heating the optical element and the installation part thereof and heating the sample measuring cell. Since the son heat sources are respectively used for heating different target areas of the sample measuring cell and are driven by the mutually independent temperature control modules, different target areas of the sample measuring cell can be selectively heated, the heating device can realize uniform heating, and the goal of temperature control can be effectively achieved; moreover, the heating structure has the characteristics of high heating efficiency, low power dissipation and high reliability.
Description
Technical field
The present invention relates to a kind of heating arrangement, be especially applied to sample measuring device heating arrangement.
Background technology
In industrial process gas on-line analysis process, sample composition is very complicated, and in the lower situation of temperature, sample easily solidifies, cause gas analyzer sample measuring cell optical element and pond body inwall contaminated, thus add frequency of maintenance and maintenance cost.In addition, in the lower situation of temperature, the moisture in sample is more prone to etchant gas analyser sample measuring cell, thus may cause gas analyzer system crash.In order to ensure the result of use of gas analyzer, under normal circumstances, the sample measuring cell of gas analyzer often arranges heating arrangement, generally heated by heating plate radiation mode, the sample measuring cell of band heating plate is placed in insulation can simultaneously, thus makes the sample in sample measuring cell keep uniform temperature.In the case, heating plate will heat sample measuring cell and whole insulation can space simultaneously, and the transfer mode of heat is mainly by radiation and the internal convection of heating plate heat, and the efficiency of heating surface is low, in thermal-insulating body, temperature distributing disproportionation is even, causes each parts of instrument to be heated the serious waste of inequality and heat.This type of type of heating can not the different parts of optionally heated sample measuring cell, can not meet the demand for heat of higher temperature, there is certain limitation.
Summary of the invention
In order to solve the problem, the invention provides the sample measuring device heating arrangement that a kind of efficiency of heating surface is high, heating zones of different targetedly.
As depicted in figs. 1 and 2, the present invention proposes a kind of sample measuring device heating arrangement, and comprise at least one sub-thermal source, described sub-thermal source dispersed placement is in each target heating region, and each sub-thermal source is driven by separate temperature control modules.
In preferably embodiment, described sample measuring device is multiple reflections spectral measurement device, comprises optical element and mounting portion, sample measuring cell and heating arrangement, and described heating arrangement is used for heat optical element and mounting portion thereof and sample measuring cell.
In preferably embodiment, described sub-thermal source acts on each target heating region in the mode contacting conduction.
In preferably embodiment, described heating arrangement is outside equipped with insulation can.
In preferably embodiment, described sub-thermal source material can be one in pottery, mica, cast copper, cast iron, cast aluminium, stainless steel, quartz and combination thereof.
By the technical scheme of above-mentioned improvement, the technique effect that this invention is useful is, sub-thermal source acts on sample measuring cell to contact conduction pattern, improves the efficiency of heating surface.Simultaneously, because sub-thermal source calorifies sample measuring cell different target region respectively, and sub-thermal source is driven by separate temperature control modules, make it possible to the zones of different of optionally heated sample measuring cell, make heating devices heat even, can effectively reach temperature control target, also there is the feature that the efficiency of heating surface is high, low in energy consumption, reliability is high simultaneously.
