By adopting a tangential air admission manner, the utility model thoroughly changes the flow direction of high-pressure process medium entering the extraction separator, effectively avoids the purge of axial air admission to products accumulated at the bottom part of the separator, improves the separating capacity of a supercritical extraction device, ensures the normal service lives of components in the supercritical extraction device, and keeps the separating capacity of the process medium. The utility model has the advantages of good separating effect, low running cost and high work efficiency.
Description
Technical field
The utility model relates to a kind of extraction separator of tangential admission, belongs to the supercritical fluid extraction equipment technical field.
Background technology
In industrial supercritical fluid extraction equipment, extraction separator commonly used comes products of separated, and the design of extraction separator, manufacturing are carried out with reference to the related request in standard GB 150 and " the safe technology of pressure vessel supervision rules ".The various extraction separator that now manufactures and designs is both at home and abroad all taked axial admission, this intake method exists the strong air flow of much keeping away end: a, high pressure to enter in the container, the portioned product that can accumulate in the separator bottom after separating is blown out the vaporific of ultrafine dust, and with processing medium outflow separator, influence the separating effect of product, make " yield " of product low.B, increase the operating cost of supercritical extraction unit, reduce equipment on-stream time.The product that flows out with processing medium will accumulate in inner-walls of duct, pipeline valve and other container; pipeline and pipeline valve are stopped up; normal operation for holding device; have to shut down pipeline, pipeline valve and container are cleaned; and must lay in a certain amount of valve element; the operating cost of increase equipment reduces its normal boot-strap time.C, processing medium quality descend, and influence its extracting power.The extracting power of processing medium depends on its purity, and the product that is blown to ultrafine dust is mixed in the processing medium, and the purity of processing medium is descended, and makes its extracting power also follow decline, finally influences the extracting power of supercritical extraction unit.Therefore the result of use of existing extraction separator still is not ideal enough.
The utility model content
The purpose of this utility model is: provide the extraction separator of the tangential admission that a kind of separating effect is better, operating cost is lower and operating efficiency is higher, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises top cover, autoclave body and separator support, top cover covers in the upper port of autoclave body and by bolt and is connected on the autoclave body, autoclave body is installed on the separator support, on top cover, be provided with the processing medium import, and the air-flow guiding tube is installed in the processing medium import, the epimere of air-flow guiding tube partly is a straight tube, its hypomere partly is the pipeline of toroidal, and the gas outlet of air-flow guiding tube is located at the pipeline position of toroidal, be provided with the processing medium outlet at the upper position place of autoclave body, be provided with products export at the bottom position place of autoclave body.
The circumference of the pipeline of air-flow guiding tube hypomere part toroidal is parallel with autoclave body inner chamber circumference.
Be with airtight heat tracing chuck in the outside of autoclave body, and be provided with the import of heating process medium, be provided with the heating process media outlet on the top of heat tracing chuck in the bottom of heat tracing chuck.
Between top cover and autoclave body, be provided with sealing ring.
Owing to adopted technique scheme, the utility model is taked fundamentally to have avoided the existing in prior technology problem in company with the tangential mode that sprays of gas to the processing medium that enters in the extraction separator.The utility model has thoroughly changed the flow direction that the high-pressure process medium enters extraction separator, avoided the axial admission mode separator bottom to be accumulated the purging of product effectively, improved the separating power of supercritical extraction unit, guarantee respectively to form in the supercritical extraction unit operate as normal life-span of components and parts, kept the due extracting power of processing medium.The utility model uses proof the utility model that product is had good separating effect through the experiment of long period, has reached its intended purposes.The utility model can be realized effective separation of product in extraction process, and reduces the operating cost of equipment, makes the processing medium extracting power be able to effective performance.So the utility model compared with prior art, the utlity model has good separating effect, operating cost is low and the advantage of high efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Drawing reference numeral explanation: 1-top cover, 2-sealing ring, 3-autoclave body, 4-heat tracing chuck, 5-air-flow guiding tube, 6-separator support, the import of A-processing medium, the outlet of B-processing medium, C-products export, the import of D-heating process medium, E-heating process media outlet.
The specific embodiment
Embodiment of the present utility model: structure of the present utility model as shown in Figure 1, top cover 1, the structure of autoclave body 3 and separator support 6 can be made in the usual way, top cover 1 covered in the upper port of autoclave body 3 and by bolt be connected on the autoclave body 3, for sealing effectiveness better, sealing ring 2 can filled up between top cover 1 and the autoclave body 3 again, autoclave body 3 is installed on the separator support 6, during making, on top cover 1, produce processing medium import A earlier, and on processing medium import A, install air-flow guiding tube 5, and air-flow guiding tube 5 is arranged in the inner chamber of autoclave body 3, the epimere of air-flow guiding tube 5 partly is made into the straight tube shape, its hypomere partly is made into the pipeline of toroidal, and the gas outlet of air-flow guiding tube 5 is located at the pipe end of toroidal, make the circumference of pipeline of air-flow guiding tube 5 hypomere part toroidals parallel simultaneously with autoclave body 3 inner chamber circumference, produce processing medium outlet B at the upper position place of autoclave body 3, produce products export C at the bottom position place of autoclave body 3 simultaneously; In order to heat conveniently, can be at airtight heat tracing chuck 4 of the outside of autoclave body 3 cover, and produce heating process medium import D in the bottom of heat tracing chuck 4, simultaneously produce heating process media outlet E on the top of heat tracing chuck 4.
