Description

The solvent circulation is extracted economic benefits and social benefits and is concentrated unit
Technical field
The utility model relates to a kind of Chinese medicine concentration extraction equipment.
Background technology
The extracting technique of Chinese medicine that concentrates as the advanced person of developing is in recent years extracted in hot reflux, and just towards application direction development widely, it has than static state extracts very significant advantage.The former category that ought to belong to leaching of traditional Chinese medicine extraction, whole leaching process comes down to soluble solute and transfer to mass transport process in the liquid phase by solid phase under the effect through physics or chemistry, whole process is abideed by diffusion principle and is achieved, and the motive force of mass transfer is a concentration difference.The concentration gradient of soluble substance and solvent in the raising medicinal material, diffusivity is just strong more, and this just can accelerate rate of extraction.The hot reflux extracting-concentration machine group, a large amount of secondary steams that is produced that concentrates is turned back in the extractor as extractor new solvent and thermal source through being condensed into hot liquid, not only saved the energy, make the concentration difference of medicinal material and solvent keep higher gradient again, accelerate the leaching velocity of active ingredient greatly, shortened extraction time.Therefore, dynamic extraction process replaces the developing direction of static extraction process as Chinese medicine industry extractive technique, has been inexorable trend from now on, and Dynamic Extraction concentrates unit and also can develop towards universalness.
Look into Chinese patent database, it is 03100438.5 that application number is arranged, name is called in the specification of " Traditional Chinese medicine abstraction concentration craft and apparatus " patent of invention, following content is disclosed: a kind of equipment of traditional Chinese medicine extraction concentration technology, include extractor, evaporimeter and condenser, it is characterized in that being provided with between extractor and the condenser vacuum switch, described extractor bottom is communicated with evaporimeter by pipeline, evaporimeter is communicated with by pipeline with condenser, and described vacuum switch is communicated with the top of extractor.The traditional Chinese medicine extraction concentrator of this structure, though the secondary steam that evaporimeter is produced turns back in the extractor as extractor new solvent and thermal source through being condensed into hot liquid, but there are the following problems also: when the condensation of first secondary steam becomes hot liquid, its condensation latent heat is not fully utilized, increased the consumption of cooling liquid greatly, caused waste the energy.This traditional Chinese medicine extraction concentrator belongs to the extraction concentrator of single-action configuration, the height of the condenser of this extraction concentrator installation simultaneously will have certain height poor with evaporimeter, this has proposed higher requirement with regard to the factory building height that requires this extraction concentrator is installed, and domestic hot reflux extracting-concentration machine group mostly is the unit that belongs to the single-action configuration at present.Look into Chinese patent database again, one patent No. is 200520103480.0, name is called the utility model patent of " hot reflux is extracted multiple-effect and concentrated unit ", disclose following content: a kind of hot reflux is extracted multiple-effect and is concentrated unit, include extractor, the extractor liquid outlet is connected to basket filter by pipeline, the basket filter lower end connects enrichment facility by pipeline, described enrichment facility is two effects, every effect enrichment facility has included heat exchanger and vaporization chamber, first imitates the heat exchanger sidewall is provided with vapour inlet and outlet, the heat exchanger top and bottom connect first by pipeline respectively and imitate vaporization chamber, first imitates vaporization chamber upper end vapor outlet port is connected to the second effect heat exchanger by pipeline vapour inlet, second imitates the heat exchanger top and bottom connects the second effect vaporization chamber by pipeline respectively, second imitates the heat exchanger lower end establishes the vapor-liquid separation pipeline, condensate liquid end pipeline directly connects vapour liquid separator, steam pipe end pipeline is connected to condenser, second imitates vaporization chamber upper end vapor outlet port connects condenser, the condenser below connects vapour liquid separator by pipeline, vacuum extractor is established in the vapour liquid separator upper end, and the lower end is connected to extractor by pipeline and pump.The extraction enrichment facility of this structure has just carried out sufficient utilization to the condensation latent heat of secondary steam, has reduced the waste of the energy.But it will keep entire equipment normally to move, and need imitate enrichment facilities to two and condenser be installed in the extractor top, and its difference in height is had certain requirement, thereby still the height of factory building be had requirement.
The utility model content
In view of the problem that background technology exists, the technical problems to be solved in the utility model provides a kind of solvent circulation to the factory building height no requirement (NR) and extracts the concentrated unit of economic benefits and social benefits.
For solving the problems of the technologies described above, the utility model adopts following technical scheme to realize: a kind of solvent circulation is extracted economic benefits and social benefits and is concentrated unit, comprise extractor, enrichment facility and cooling tower, described enrichment facility is two effects, every effect enrichment facility includes evaporimeter and reboiler, first imitates the reboiler sidewall is provided with vapour inlet and outlet, the top and bottom of reboiler connect first single-effect evaporator by pipeline respectively, the vapor outlet port of first single-effect evaporator upper end connects the vapour inlet of the second effect reboiler by pipeline, second imitates the reboiler top and bottom connects second single-effect evaporator by pipeline respectively, the vapor outlet port of second single-effect evaporator is communicated with the cooling tower upper end, it is characterized in that the condensation heat liquid outlet of the described second single-effect evaporator lower end is communicated with extractor by delivery pump; The condensed fluid outlet of described cooling tower lower end is communicated with extractor by described delivery pump; The tail gas outlet of described cooling tower is connected with condenser; The inside, lower end of described second single-effect evaporator and cooling tower is equipped with the vacuum switch.
This economic benefits and social benefits are extracted and are concentrated unit, has very significant beneficial effect: 1, kept the elite that Dynamic Extraction concentrates, a large amount of secondary steams that produce that concentrate are condensed into hot liquid, turn back to extractor as the novel solvent and the thermal source that extract, make and remain higher concentration gradient in the extractor, accelerate leaching velocity, shortened extraction time; 2, the condensation latent heat of secondary steam is fully used, and has saved cooling water, and energy-saving effect is quite remarkable, extracts concentrator with single-action and compares, and has saved about 40%; Particularly in big production, have sizable economic benefit and social benefit; 3, the condensation heat liquid outlet in the second single-effect evaporator lower end is communicated with extractor by delivery pump, has solved the problem of difference in height between condenser and the evaporimeter, and feasible height to factory building no longer includes requirement, and both can install by coordination; 4, secondary steam is through three grades condensation, the proportion of goods damageds of alcohol when having guaranteed alcohol extracting; 5, the extraction concentrator of this structure, but not only but alcohol extracting but also water were carried; 6, the vacuum switch is installed in the inside of evaporimeter and cooling tower, makes complete equipment become succinctly, not the side of occupation of land.
