Abstract
The invention discloses a rapid cooling structure for a gas chromatograph column box. The rapid cooling structure for the gas chromatograph column box comprises a column box (1), and is characterized in that a small fan (2) is installed at a cold air inlet, and a seven-shaped air-out chimney (3) is installed at a hot air outlet; and an outlet of the air-out chimney (3) is upward. According to the rapid cooling structure for the gas chromatograph column box provided by the invention, the gas chromatograph column box is greatly increased, the equal condition is small, and the cooling speed is improved by more than 3 times, so that the service efficiency of a gas chromatograph is greatly improved.
Description
Technical field
The invention belongs to the species analysis instrument field, specifically just relate to a kind of gas chromatograph post case fast cooling structure.
Background technology
Gas chromatograph is the instrument that material is carried out qualitative and quantitative analysis with vapor-phase chromatography, be used for carrying out analyzing and testing to respectively forming to divide in the mixed gas, gas chromatograph is a kind of separation, analysis tool of many mixture, it is take gas as mobile phase, adopts the column chromatography technology of douche.When the amalyzing substances of many components enters into chromatographic column, because the gas phase of each component in chromatographic column is different with the partition factor between the immobile liquid liquid phase, therefore each component is also just different in the travelling speed of chromatographic column, through behind certain column length, order is left chromatographic column and is entered detecting device, be converted to afterwards after testing electric signal and deliver to the data processing work station, thereby finished the qualitative and quantitative analysis to measured matter.Gas chromatograph is used very wide at aspects such as oil, chemical industry, biological chemistry, medical and health, food industry, environmental protection.It is except being used for quantitatively and the qualitative analysis, can also fixing the physicochemical constants such as partition factor, activity coefficient, molecular weight and specific surface area of going up mutually by working sample.
The essential structure of gas chromatograph has two parts, be analytic unit and display unit, be surrounded by the post case in the analytic unit, as shown in Figure 1, existing post case partial volume is larger, for insulation, filled a large amount of heat-preservation cotton between the inner bag of post case and the outer courage, in the course of work, realize that by the switch of control back pullout (BPO) air and the circulation of air outside the casing in the casing realize cooling, but because exhausr port is adjacent with air intake opening, some has entered the post case by following air intake opening again the hot gas that top exhausr port is discharged, and causes effective cold air fewer, has prolonged temperature fall time, in addition for all even coolings of temperature of air in the case, post case inner blower rotating speed can only be constant, thereby existing post box structure cooling rate is very slow, inefficiency, greatly consume the time of staff's analytic sample, seriously reduced work efficiency.
Summary of the invention
Technical matters to be solved by this invention is to underspeed slow for existing gas chromatograph post case temperature, cause the excessively low drawback of analytic sample efficient, the invention provides a kind of gas chromatograph post case fast cooling structure, accelerate post case cooling rate, increase work efficiency.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of gas chromatograph post case fast cooling structure, and it comprises the post case, it is characterized in that: at little blower fan of described post case cold wind inflow point's installation, 7 font air-out chimneys are installed at the hot-blast outlet place, and the air-out chimney breast upwards
The specification of described little blower fan is 12 volts of DC voltage, 2.5 amperes.
45° angle falls at described 7 font air-out chimney turnings.
Blower fan in the described post case is selected capacitor-run asynchronous motor, and voltage 200V, electric current be less than 0.35A, rotating speed 2800RPM, power 40W.
Beneficial effect
The present invention has improved the cooling rate of gas chromatograph post case greatly, and equal conditions is little, and cooling rate of the present invention has improved more than 3 times.Thereby improved greatly the service efficiency of gas chromatograph.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
A kind of gas chromatograph post case fast cooling structure, it comprises post case 1, it is characterized in that: at little blower fan 2 of described post case 1 cold wind inflow point installation, 7 font air-out chimneys 3 are installed at the hot-blast outlet place, and 3 outlets of air-out chimney upwards
The specification of described little blower fan 2 is 12 volts of DC voltage, 2.5 amperes.
45° angle falls at described 7 font air-out chimneys 3 turnings.
Blower fan in the described post case 1 is selected capacitor-run asynchronous motor, and voltage 200V, electric current be less than 0.35A, rotating speed 2800RPM, power 40W.
The present invention has improved the cooling rate of gas chromatograph post case greatly, and equal conditions is little, and cooling rate of the present invention has improved more than 3 times.Thereby improved greatly the service efficiency of gas chromatograph.
