Description
Technical field
The present invention relates to laboratory for the preparation of the instrument of distilled water, specifically the water circulation method of laboratory cycle ability of swimming water still.
Background technology
In the experiment of hospital, pharmaceutical factory, biologic product company, scientific research institutions and school, often need to use a large amount of distilled water, comprise single water, distilled water and tri-distilled water of steaming.And make distilled water, tap water heating to boiling need be become after steam state separatedly with other impurity, then water vapour is condensed through cooling tube and again becomes liquid state again and be distilled water.For this reason, a large amount of water of making distilled water process need carries out cooling, and cooling water, because not having retracting device just directly to enter sewer, causes a large amount of wastes.
In the preparation process of distilled water, we find the use for laboratory water still of selling on market, no matter be any type, the defect that their exist mainly contain following some: first, mostly heater is spiral heating tube if being used, and be arranged in heating staving, for preventing dry combustion method, requirement remains that the water surface will be higher than the height of spiral heating tube in the process of heating, and this just requires initial water amount to want large; Moreover for a long time, heating repeatedly, spiral heating tube surface can form fouling, affect heat exchange, these factors have not only increased power consumption, also make output efficiency reduction.The second, spiral heating tube surface and thermotank encrustation be easy-clear not, and inconvenient maintenance, because spiral heating tube is fixed on thermotank bottom.The 3rd, cooling water does not have retracting device, directly enters sewer, causes the waste of water resource.Through experiment measuring and calculating, with the every preparation of single water still 10L distilled water (10L/h), need the about 200L of cooling water, if use 20L distilled water every day by a laboratory, within 1 year so, (by 300 days, calculating) will waste nearly 120 tons of water, adopt the water consumption of distilled water device and tri-distilled water device also to want many.
Within 2008, water resources in china communique shows, 2008, Average per capita water consumption was 446 m
3.Wherein water consumption is greater than 600 m per capita
3have Xinjiang, Tibet, Ningxia, Heilungkiang, Jiangsu, the Inner Mongol, Guangxi, Shanghai, 9, Qinghai province (autonomous region, municipality directly under the Central Government), be less than 300 m
3have Shanxi, Tianjin, Beijing, Shaanxi, Shandong, Henan, Sichuan, Guizhou, Hebei, 10 provinces in Chongqing (municipality directly under the Central Government), wherein Shanxi is minimum, only 167 m
3.According to internationally recognized standard, water resource is lower than 3000 m per capita
3for slight lack of water; Water resource is lower than 2000 m per capita
3for moderate lack of water; Water resource is lower than 1000 m per capita
3for serious water shortage; Water resource is lower than 500 m per capita
3for extreme lack of water.There are 16 provinces (district, city) water resource of per capita (not comprising the water that passes by) in China at present lower than serious water shortage line, has 6 provinces, district (Ningxia, Hebei, Shandong, Henan, Shanxi, Jiangsu) water resource of per capita lower than 500 m
3.
