Description
Technical field
This utility model relates to chromatography, particularly to heat of adsorption desorption apparatus.
Background technology
Cryogenic absorption is widely used in the lower boiling volatile organic matter of analysis and separates with thermal analysis apparatus, enriched sample the most at low temperatures, sample desorbing under high temperature, thus realizes the separation of sample.
The most conventional cryogenic absorption mode mainly has: semiconductor element cryogenic refrigeration；Cold-producing medium (as liquid nitrogen cryogenics freezes)；And refrigeration machine Cyroadsorption resolver.
There is the shortcoming that cryogenic temperature is low in the refrigeration of quasiconductor, minimum cryogenic temperature only-30 degree；
There is cold-producing medium and consume big problem in chiller refrigeration.
The cryogenic absorption device of existing refrigeration machine refrigeration modes can produce the low temperature of minimum-170 degree, but existing structure exists problem below:
The most difficult in maintenance, enrichment pipe is placed in the copper pipe of refrigeration machine, needs to dismantle substantial amounts of joint, wiring in narrow space during replacing；Being then enriched with pull-out in Guan Congcong copper pipe, the space, left and right needing instrument is sufficiently large, and this can cause instrument volume to become big.
2. there is substantial amounts of icing in refrigeration copper tube and source, and easily and the heating wires short-circuit risks of enrichment pipe, freeze the serious problems such as may cause that the thermometric of thermocouple is forbidden.
Utility model content
In order to solve the deficiency in above-mentioned prior art, this utility model provides that a kind of volume is little, the heat of adsorption desorption apparatus of convenient disassembly.
The purpose of this utility model is achieved through the following technical solutions:
A kind of heat of adsorption desorption apparatus, described heat of adsorption desorption apparatus includes refrigeration machine, enrichment pipe；Described heat of adsorption desorption apparatus farther includes:
Heat carrier, described heat carrier is arranged on the chill surface of described refrigeration machine, and described enrichment pipe is embedded in described heat carrier deviously；
Thermal insulation cover, described thermal insulation cover is arranged on the first heat carrier and the periphery of the second heat carrier, and is fixed on described refrigeration machine；Air inlet and gas outlet it is provided with on described thermal insulation cover.
According to above-mentioned heat of adsorption desorption apparatus, it is preferable that described heat carrier includes:
First heat carrier, the side of described first heat carrier is arranged on the chill surface of described refrigeration machine, and the opposite side back to chill surface has the first mounting groove of bending；
Second heat carrier, the side facing to described first heat carrier of described second heat carrier has the second mounting groove mated with described first mounting groove；Enrichment pipe is arranged in the space of described first mounting groove and the formation of the second mounting groove.
According to above-mentioned heat of adsorption desorption apparatus, it is preferable that the inlet and outlet of described enrichment pipe is in the same side of described heat carrier.
According to above-mentioned heat of adsorption desorption apparatus, alternatively, the part through described thermal insulation cover of described enrichment pipe is cased with ceramic cylinder.
According to above-mentioned heat of adsorption desorption apparatus, it is preferable that described gas outlet is the gap between described ceramic cylinder and thermal insulation cover.
According to above-mentioned heat of adsorption desorption apparatus, alternatively, described heat of adsorption desorption apparatus farther includes:
Heating member, described heating member is arranged on described enrichment pipe and stretches out in the part of thermal insulation cover.
Compared with prior art, this utility model has the beneficial effect that
1. enrichment pipe is easy to maintenance, and dismantlement work amount is greatly lowered；
2. the volume of this device can structure than before greatly reduce；
The most there is not icing phenomenon, the thermometric that solving freezes causes is forbidden, the fusing that freezes produce waste water etc. problem.
