Abstract
The invention discloses a kind of biodiesel heating flash evaporation device, it is made up of upper, middle and lower three part, three-in-one device is connected to form, the falling liquid film tube still heater that described top comprises the top cleaning coil pipe be arranged in upper cover, is positioned at the feed liquor distributor below top cleaning coil pipe and is arranged on below feed liquor distributor by vessel flange; Described middle part comprises and is located at reception liquid trap below falling liquid film tube still heater, the vapour liquid separator of band filter screen disk and the middle part cleaning coil pipe that is located between the two; Described bottom comprises the polylith flash distillation distributing disc that short transverse is evenly arranged, and all steam guiding tube is housed in every block dish.This structure-biological diesel heating flash distillation plant has pipeline when production of biodiesel and equipment cleaning labour intensity is low, production is carried out continuously, energy-efficient feature.
Description
Technical field
The present invention relates to fine chemistry industry production equipment, particularly in production of biodiesel process for biodiesel heating flash evaporation device that low component removes.
Background technology
The main raw material of production of biodiesel is waste animal and vegetable oil, for catering trade, i.e. and our said waste oil, hogwash fat and frying oil usually.The carbochain of waste animal and vegetable oil consists of C8-C22, and its carbochain composition is distributed more widely, and the primary chemical composition of biodiesel is C16-C18, and qualified biodiesel needs to remove the low component before C14.Current production biodiesel removes the apparatus and process that low component generally adopts heater, delivery pump, flash column, foam removal is separated vapour-liquid.The defect existed is: the waste oil utilized due to production of biodiesel exists plurality of impurities, and the viscosity of material is larger in production process, poor fluidity, production technology circuit is long and complicated, and particularly when winter produces, difference variation is large, very easily blocking pipe and equipment in production, constantly carry out the work of removing pipeline and equipment blocking, cause production not carry out continuously, have a strong impact on productivity effect, also increase staff labor intensity simultaneously.
Summary of the invention
When the object of this invention is to provide a kind of production of biodiesel pipeline and equipment cleaning labour intensity is low, produce carry out continuously, energy-efficient biodiesel heating flash evaporation device.
For realizing above object, biodiesel heating flash evaporation device of the present invention is made up of upper, middle and lower three part, three-in-one device is connected to form, the falling liquid film tube still heater that described top comprises the top cleaning coil pipe be arranged in upper cover, is positioned at the feed liquor distributor below top cleaning coil pipe and is arranged on below feed liquor distributor by vessel flange; Described middle part comprises and is located at reception liquid trap below falling liquid film tube still heater, the vapour liquid separator of band filter screen disk and the middle part cleaning coil pipe that is located between the two; Described bottom comprises the polylith flash distillation distributing disc that short transverse is evenly arranged, and all steam guiding tube is housed in every block dish.
Described flash distillation distributing disc is five pieces.
The top cleaning coil pipe of above-mentioned biodiesel heating flash evaporation device and middle part cleaning coil pipe, by adding hot water or steam cleans facility in tower, disposablely from top to bottom can clean feed liquor distributor, falling liquid film tube still heater, receive the flash distillation distributing disc of liquid trap, vapour liquid separator and bottom.
Said structure biodiesel heating flash evaporation device has following positive effect: 1. realize falling film heating flash distillation integration, thus eliminates the defect that original technology adopts heater, delivery pump, flash column, the apparatus and process of foam removal separation vapour-liquid brings; 2. improve the equipment cycle of operation, reduce heat waste, reduce clogging, steam saving, reaches energy-saving effect; 3. labor strength is reduced; 4. reduce device fabrication cost, save equipment investment; 5. abundant Appropriate application hall space; 6. simplification of flowsheet; 7. the discharge of waste water is reduced.
Accompanying drawing explanation
Accompanying drawing is biodiesel heating flash evaporation device principal section structural representation of the present invention.
Reference numeral: top cleaning coil pipe 1, feed liquor distributor 2, falling liquid film tube still heater 3, reception liquid trap 4, middle part cleaning coil pipe 5, vapour liquid separator 6, flash distillation distributing disc 7 and steam guiding tube 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, biodiesel heating flash evaporation device of the present invention is described in further detail.
Shown in accompanying drawing, biodiesel heating flash evaporation device of the present invention is made up of upper, middle and lower three part, three-in-one device is connected to form, the falling liquid film tube still heater 3 that described top comprises the top cleaning coil pipe 1 be arranged in upper cover, is positioned at the feed liquor distributor 2 below top cleaning coil pipe and is arranged on below feed liquor distributor by vessel flange; Described middle part comprises and is located at reception liquid trap 4 below falling liquid film tube still heater, the vapour liquid separator 6 of band filter screen disk and the middle part cleaning coil pipe 5 that is located between the two; Described bottom comprises five pieces of flash distillation distributing discs 7 that short transverse is evenly arranged, and in every block dish, steam guiding tube 8 is all housed.
During production, biodiesel is entered by the feed liquor distributor 2 on top containing low component materials, heat up through falling liquid film tube still heater 3, drop to flash distillation distributing disc 7 flash distillation receiving liquid trap 4 bottom, low component gas through tower tray flash distillation rise to vapour liquid separator 6 heat after with azeotropic biodiesel vapor-liquid separation, gas cools recovery by vacuum outlet to subsequent condensation device, and liquid biological diesel return is to tower tray; The biodiesel being removed continuously low component to decline flash distillation step by step from tower tray, then from the lower part outlet of tower to lower operation, thus realize completing in heating, flash distillation, vapor-liquid separation integrated device.
At production certain phase, owing to containing toughness foreign material in material, easily there is channel blockage and affect production, coil pipe 1 and middle part need be cleaned by top to clean coil pipe 5 and add hot water or steam cleans, disposablely from top to bottom can clean feed liquor distributor 2, falling liquid film tube still heater 3, receive the flash distillation distributing disc 7 of liquid trap 4, vapour liquid separator 6 and bottom.
Coming into operation of this biodiesel heating flash evaporation device substantially reduces biodiesel production method pipeline flow process, has both saved steam consumption, has additionally reduced the discharge of waste water.
