The utility model provides a hot-pump type liquid medicine evaporator which is mainly composed of a single-effect falling-film evaporator, a preheater, a steam jet compressor, a demister, a circulating pump, a hydraulic jet vacuum pump and a concentrated liquid storage. The hot-pump type liquid medicine evaporator is characterized in that the evaporator forms a tubular shape. A discharging pipe with big diameter is arranged at the bottom. The lower part is connected with the demister. The steam jet compressor is provided with a bypass valve which can be directly communicated with the high-temperature steam. The utility model has the advantages of water saving, energy saving, big specific gravity of the finished concentrated liquid, high concentration, simple structure and high rate of finished products and is convenient to operate, repair and wash.
Description
This utility model relates to a kind of medicinal liquid vaporising device, particularly heat-pump-type medicinal liquid vaporising device.
In the prior art, the evaporation and concentration of extracts of Chinese herbal medicine is used decompression evaporator always, outer circulation decompression evaporator and triple effect evaporator etc., and the ubiquity heat transfer coefficient is low, and finished product concentration is low, and easily fouling, foam are serious, energy consumption height, shortcoming such as the time is long.
The purpose of this utility model is intended to avoid the deficiencies in the prior art and provides a kind of device structure simple, and operating maintenance is convenient, and the energy-saving and water-saving effect is remarkable, and concentrated solution is than the heat-pump-type medicinal liquid vaporizer great, that concentration is high.
The purpose of this utility model is to realize like this; A kind of heat-pump-type medicinal liquid vaporising device mainly comprises single-action falling film evaporator (abbreviation vaporizer), preheater, steam-jet ejector, demister, circulating pump, water-jet vacuum pump and concentrated solution storage tank; It is characterized in that vaporizer is a shell and tube, the major diameter discharging tube is equipped with in its bottom, and the indirect steam outlet of its underpart connects with demister; Steam-jet ejector has bypass valve, can directly feed high-temperature steam.
---the evaporation tube of described vaporizer (diameter is D) is a shell and tube, vaporizer top be the feed liquid distributor of uniform sieve aperture, the bottom has large diameter discharging tube (diameter is d) to link to each other with the concentrated solution storage tank, and the liquid in pipe discharge speed is lower than 0.2 meter per second, and d/D is greater than 0.15.
---described steam-jet ejector one end is connected with demister through valve, and the other end links to each other with vaporizer with preheater.
Below in conjunction with drawings and Examples this utility model is further specified;
Fig. 1 is a profile floor map of the present utility model, and wherein 1 is the material liquid circulating pump, and 2 is preheater, 3 is vaporizer, 4 is discharging tube, and 5 is the concentrated solution storage tank, and 6 is demister, 7 is jet ejector, 8 is the indirect steam valve, and 9 is the jet ejector bypass valve, and 10 is the circulation line valve, 11 is dump valve, and 12 are the water-jet vacuum pump.
Fig. 2 is the evaporation structure view; Wherein 13 for not evaporating material liquid outlet, and diameter is d; 14 are the indirect steam outlet; 15 is the evaporator evaporation pipe, and feed liquid is downward along tube wall, and indirect steam is downwards middle from managing, and the diameter of vaporizer is D; 16 is the feed liquid distributor, is uniform-distribution with sieve aperture; 17 are the inlet of preheating feed liquid; 18 is the steam inlet, and 19 is condensation-water drain.
Fig. 3 is the preheater topology view; Wherein 20 are the feed liquid inlet; 21 is the preheater cylindrical shell; 22 is from the evaporator condensation water inlet; 23 is the preheater economizer bank; 24 is the high temperature material liquid outlet; 25 is the steam inlet; 26 is condensation-water drain.
This utility model is to connect like this to install: material liquid circulating pump 1 is managed in dump valve 11 and circulation line valve 10 and calandria preheater 2 and is connected, the inlet of preheating feed liquid and the steam inlet of vaporizer 3 upper ends connect with preheater, and vaporizer connects with concentrated solution storage tank 5 through discharging tube 4; The indirect steam outlet of preheater bottom links with demister 6, links through the steam inlet of indirect steam valve 8 and jet ejector 7 and preheater and vaporizer upper end again; Jet ejector bypass valve 9 in parallel.
This utility model is work like this: material liquid boosts through circulating pump 1, enter in preheater 2 pipes, carry out heat exchange raising temperature with the outer steam of pipe, enter vaporizer 3 feed spaces through 17, in the feed liquid distributor evenly enters each evaporation tube, by the outer Steam Heating evaporation of pipe, indirect steam that produces and unevaporated feed liquid are equidirectional, and feed liquid is downward along tube wall downwards, and indirect steam is downwards middle from managing, feed liquid enters concentrated solution storage tank 5 from major diameter discharging tube 4, continues circulating and evaporating; Indirect steam enters demister 6, and injected compressor 7 suction compressions improve temperature behind the droplet that separation is carried secretly, reuse as heating steam.Extract the later stage, feed concentration improves, and mobile performance descends, and this moment, indirect steam valve 8 directly fed high-temperature steam from jet ejector bypass valve 9, evaporation is proceeded, until reaching desired concentration under the big temperature difference.Close circulation line valve 10, open dump valve 11, discharge concentrated solution.
This utility model improves the flow of solution situation owing to use single-action falling liquid film circulating and evaporating concentration technology, has increased and has fallen liquid measure in the pipe, has avoided the tube surface part to lack solution and fouling has improved heat transfer coefficient, thereby has improved the concentration of evaporation efficiency and finished product.This utility model has also been used steaming almost jet ejector with its bypass operating procedure stage by stage.In morning of evaporation and concentration, most of the time in mid-term, by the jet ejector operation, make full use of the latent heat of vaporization of indirect steam, evaporation capacity is big, and energy-saving efficiency is good; In the later stage of evaporation and concentration, solution concentration improves, and the evaporation difficulty strengthens, and implement the bypass operation of jet ejector this moment, directly feeds high-temperature steam, and evaporation is proceeded under the big temperature difference, further improves finished product concentration.
The utility model is compared with at present common outer circulation single effect evaporator, and is energy-conservation more than 60%, Water saving is more than 80%; Finished product concentrate proportion is 1.3-1.45, and concentration can reach 60～80%; And device structure is simple, low cost of manufacture, and processes expend is low, and production cost descends, operation, Keep, easy to clean.
