Problems solved by technology
Because crystals may be produced, most of the existing equipment forms are kettle-type or external circulation or scraping mode evaporators. Among these methods, kettle-type evaporators have low energy utilization, low output, and large floor space; external circulation The single-batch concentration time is long, and the process takes up a large amount of material. If it is forced external circulation, the power consumption will be huge, and the final product concentration will be low; the scraper type evaporation concentrator should not have too large a heating area, so this application is also limited. limit

The invention relates to a film-falling scraping plate type multitubular evaporation concentrator, belonging to a heating device. A material cavity and a steam cavity are arranged in the inner cavity of a casing; the material cavity is communicated with a feeding tube and a discharge tube; and the steam cavity is communicated with a steam inlet tube and a steam outlet tube. The film-falling scraping plate type multitubular evaporation concentrator is characterized in that the casing is in a vertically cylindrical shape; the steam cavity is in a closed annular hollow shape; the material cavityand the steam cavity are mutually spaced; a stirring rod is arranged in the material cavity between the steam cavities; a scraping plate is arranged on the stirring rod; the scraping plate is contacted with the outer wall of the steam cavity; the stirring rod is connected with a stirring shaft; the stirring shaft passes through the casing upwards to be connected with a power shaft; the feeding tube is communicated with the top part of the inner cavity of the casing; the discharge tube is communicated with the bottom of the outer casing inner cavity; the lower part of the g inner cavity of thecasing is connected with a gas-liquid separator; and a liquid outlet of the gas-liquid separator is communicated with the discharge tube. The invention integrates the advantages of film-falling type evaporators, film-scraping type outer circle type evaporators and kiln type evaporators, has small floor area, large heating area, high heat efficiency, high yield and low energy consumption, and is beneficial to popularization and application.
Description
technical field [0001] The invention relates to a falling film scraper type multi-pipe evaporation concentrator, which belongs to heating equipment. Background technique [0002] The method of evaporating the solvent by heating the feed liquid to increase the concentration and precipitate crystals is a commonly used production unit in the field of medicine and chemical industry. Because crystals may be produced, most of the existing equipment forms are kettle-type or external circulation or scraping mode evaporators. Among these methods, kettle-type evaporators have low energy utilization, low output, and large floor space; external circulation The single-batch concentration time is long, and the process takes up a large amount of material. If it is forced external circulation, the power consumption will be huge, and the final product concentration will be low; the scraper type evaporation concentrator should not have too large a heating area, so this application is also lim...
