Consumption directly determines the cost of product, and product quality must be considered simultaneously in today of the green pharmacy of promotion energetically, the modernization of Chinese medicine
With concern product cost, by improving concentration technology so that the energy consumption of modern Chinese herbal medicine is lower, more efficient, quality is more stable.This
Utility model proposes a kind of atmospheric low-temperature concentrated traditional Chinese medicine liquid system based on heat pump, it is desirable to solve herbal pharmaceutical industry concentration technology
High energy consumption, easy fouling, drug effect loss problem.
Utility model content
In order to solve problems of the prior art, the utility model provides a kind of efficient normal pressure suitable for Chinese medicine liquid
Low temperature concentration systems, overcome the problem of herbal pharmaceutical industry concentration technology high energy consumption, easy fouling, drug effect are lost in the prior art.
The technical solution adopted in the utility model is：A kind of efficient atmospheric low-temperature heat pump suitable for Chinese medicine liquid, which is concentrated, is
System, including enclosed compression heat pump system and Chinese medicine liquid atmospheric low-temperature concentration systems, the enclosed compression heat pump system include
Pass sequentially through the circulatory system that compressor, condenser, choke valve and the evaporator of pipeline connection are constituted；The Chinese medicine liquid normal pressure is low
Warm concentration systems include head tank, and head tank is connected by pipeline with intermediate storage tank, intermediate storage tank successively with circulating pump, heat pump system
The condenser heat absorption side-entrance connection of system, condenser heat absorption side outlet is connected at the top of filler concentration tower, filler concentration tower bottom
Products pot and intermediate storage tank are connected by pipeline respectively；Air intlet connecting fan, filler concentration tower bottom is connected to by pipeline
Connection heat pump evaporator heat release side-entrance at the top of portion, filler concentration tower, evaporator heat release side outlet connection knockout drum,
Knockout drum connects solvent tank and blower fan respectively.
The air intlet is provided with screen pack, and its main function is filtering dust and solid impurity.
Demister is provided with the top of the filler concentration tower, its main function is removal Vapor Entrainment.
The beneficial effects of the utility model are：
(1) the utility model system is natural evaporation process, and evaporating temperature is relatively low, and Chinese medicine liquid will not be because temperature is high and becomes
Matter, loses heat-sensitive substance, process equipment will not be because of the too high generation scale formation of temperature；
(2) heat and cold are provided simultaneously by heat pump, energy consumption is far below heating evaporation technology；
(3) it can also intermittently can operate continuously.
