Description
Technical field
The invention belongs to laboratory installation, relate to the Simple water circulation device that a kind of laboratory Rotary Evaporators is supporting, be applied to water or other liquid as a kind of cooling water backflow recycle device during cooling agent.
Background technology
Water is the important component part of natural resources, be the main matter of zoic structure composition and vital movement basic.From global range, water is the tie connecting all ecosystems, and the flowing that natural ecosystems can control water can constantly impel water purification and circulation again.Therefore water is in natural environment, for the biological and mankind existence there is decisive meaning.
According to the estimation of hydro_geography scholar, tellurian gross amount of water resources is about 13.8 hundred million cubic kilometers, and wherein 97.5% is seawater (13.45 hundred million cubic kilometers).Fresh water only accounts for 2.5%, and wherein the overwhelming majority is polar ice snow ice river and underground water, and what the suitable mankind enjoyed is only 0.01%.In 20th century, world population adds twice, and mankind's use water adds 5 times.Many countries are faced with water resources crisis in the world: 1,200,000,000 people's water shortages, and 3,000,000,000 people lack and use water hygiene facility, have 300 ten thousand to 400 ten thousand people to die from the disease relevant with water every year.By 2025, water crisis will spread to 48 countries, and 3,500,000,000 people are stranded by water.The ecosystem that water resources crisis brings worsens and bio-diversity is destroyed, also by serious threat human survival.
At present, the waste problem for water resource has caused society to show great attention to, and China is also stepping up resource-conserving, the construction of friendly environment society.The waste problem of water resource in laboratory, often by people are ignored.In general chemical laboratory, the purification often relating to material is with concentrated, and Rotary Evaporators is exactly one of conventional instrument of enriched compound of purifying in laboratory conditions.At present, Rotary Evaporators is mainly used in a large amount of effumability solvent of continuous still at reduced pressure conditions, and general principle is exactly decompression distillation, when solvent distills, distilling flask is in continuous rotation, and the general water flowing of serpentine condenser, with heat exchange, makes the organic solvent liquefaction by evaporating get back to receiving bottle.But the cooling water at present in order to heat exchange is one-way flow, namely direct from water tap access, then after heat exchange, directly enter sewer.With 6 ml/s flow velocity conservative estimations, the running time of one hour just can consume about 22 L water.Assuming that distillation 500 ml ethanolic solution, ethanol gasification temperature under vacuum about 50 DEG C, post liquefaction temperature is about 25 DEG C, the heat that then this process exchanges is 23.67 KJ, take water as cooling agent, suppose that in cooling procedure, water temperature rises 5 DEG C, then need the water yield probably at 1.13 L, and the actual amount of water of conservative estimation conventional method consumption is theoretical more than 20 times.Rotary Evaporators cooling water used is only just used as heat exchange, is not polluted, directly enters sewer and cause great waste.Cause the main cause of this phenomenon to be the cooling device that cooling water circulating device on market is all equipped with recirculation water, need relatively independent cooling system, equipment more complicated, price is all in several thousand units even up to ten thousand.But for general use for laboratory Rotary Evaporators, it is worth several thousand yuan only.Therefore, consider that short-period cost is that this device removes to buy cooling water circulating device on market and uneconomical, so also just cause current situation.Develop and can rationally reclaim cooling water and recycle, the Appropriate application for water resource is significant.
Design a circulatory system that cooling water backflow can be reused significant to laboratory using water wisely, this device should meet following requirement: (1) can make cooling water circulation use; (2) different according to distillation solvent reasonable adjusting flow velocitys, meets the needs of heat exchange.(3) reasonable price, is beneficial to popularization.
