Description
Technical field
The present invention relates to the technical fields of analysis instrument, and in particular to a kind of adsorption/desorption pipe using thermal control valve,
It being capable of volatile organic compounds (VOC) in enriched gas.
Background technique
The substances such as the VOC in gas are harmful to the human body, intensive, the interior of space sealing, vehicle especially for product mode
Interior, the concentration after accumulation is higher, and harm to the human body is bigger, and needs to be arranged in the detection device of air V OC in the prior art
Pressure pump, equipment are larger, it has not been convenient to and it carries, especially in field work, analysis can not be made to the ingredient of gas in time,
Inconvenience is brought to the work of testing staff.
Summary of the invention
The present invention provides integrated automation control analysis instrument thermal control valve and based on the adsorption/desorption of this technological development
Pipe.The purpose of the present invention is providing a kind of scheme of miniaturization for the detection of air V OC hand-held, pressure can not had to using this scheme
The device space is greatly saved in power pump, and cooperation hand-held gas chromatography-mass spectrum is, it can be achieved that field condition sampling, on-site test.
Solution of the invention is that lower forward direction valve inlet connects compression under test gas, and lower reverse valve inlet connects compressed nitrogen,
Under test gas passes through adsorption/desorption pipe when room temperature, and the VOC in gas is adsorbed filler and is adsorbed, and is emptied by upper positive valve outlet,
It is heated by the external heater strip of adsorption/desorption device, in preset temperature on positive valve, lower positive valve close, it is upper reverse
Valve, lower positive valve are opened, and compressed nitrogen purges adsorption stuffing, and purge gas enters detection by upper reverse valve outlet
Device.
Wherein, be ellipse inside the upper positive valve and the lower positive valve, and comprising positive valve expanded spheres and
Positive valve chest, it is described forward direction valve expanded spheres be spheroidal, be made of heat deformation material, can after reaching preset temperature point body
Product significantly increases, and the volume of forward direction valve expanded spheres is less than cavity volume, gas when the upper positive valve and the lower positive valve room temperature
Stream can pass through, and when temperature reaches the preset temperature, volume is dramatically increased, and block cavity outlet, the upper forward direction
Valve and the lower positive valve are closed.
Wherein, be ellipse inside the upper reverse valve and the lower reverse valve, and comprising reverse valve expanded spheres and
Reverse valve chest, the reverse valve expanded spheres are spheroidal, are made of heat deformation material, can be after reaching the preset temperature
Volume is substantially reduced, and expanded spheres volume is greater than cavity volume when the upper reverse valve and the lower reverse valve room temperature, and air-flow can not
Pass through, when temperature reaches the preset temperature, volume is substantially reduced, and exposes cavity outlet, the upper reverse valve and described
Reverse valve is opened down.
The beneficial effects of the present invention are: pressure pump can not had to using this scheme, can be completed in gas without power source
The pretreatment process of volatile organic compounds (VOC), greatly reduces pre-processing device volume, testing staff is facilitated to take with oneself
Band cooperates with hand-held gas chromatography-mass spectrum detector, can obtain the data of VOC content in gas in real time.
