Abstract
The utility model relates to a flash evaporator; the top part of an evaporating chamber is provided with a centrifugal atomizer. Feed liquid is heated by a heater to a boiling point but is not boiling, and then is sprayed into little fog-shaped liquid drops through the centrifugal atomizer in the flash evaporator, so as to cause water to be evaporated rapidly. The evaporator combined centrifugal atomization and vacuum concentration into integration, and evaporation rate has breakthrough. The utility model thoroughly overcomes the defects that the evaporating surfaces of the existing various evaporators are easy to form scale, concentration end point is not easy to be controlled, the loss rate of material increases with the increase of solute concentration, etc. The utility model can be widely used for the concentration of thermal sensitive materials in the technical field of pharmacy, antiseptics, foods and chemical industries.
Description
The utility model relates to evaporimeter, particularly a kind of flash evaporator.
For heat sensitive material such as antibiotic solution, fruit juice etc., in order to guarantee product quality, need to adopt vacuumizing to reduce the boiling point of solution, make feed liquid evaporation and concentration at a lower temperature.Existing a kind of centrifugal film evaporator, this evaporimeter is on a hollow rotary shaft equal intervals ground several stacked heating plates to be installed, heating plate is the interlayer bullet, logical heating steam in the interlayer, by independent pipe turnover, pipe also places in the hollow rotary shaft respectively for heating steam and steam condensate (SC).Feed liquid is led to a person in charge and several short arms that nozzle is housed after the pump pressurization, the direction of following the lamination rotation sprays on the heating surface of rotation.Because the lamination action of centrifugal force, feed liquid is the membranaceous laminate surface of passing rapidly and enters lamination edge axial hole, flow in the top collector groove.Indirect steam is drawn by lamination central authorities, condensation in plate heat exchanger, and other has set up steam jet pump makes whole system become vacuum.The shortcoming of this device is complex structure, makes maintenance difficult, price height, and atomizing effect is not ideal enough.Particularly feed liquid has change in concentration on heating surface, fouling easily, and easily make the heat sensitive material coking.
The purpose of this utility model is the above-mentioned shortcoming that will overcome prior art, for heat sensitive material, biochemical product provide a kind of traditional vacuum atomizing flash evaporator, the original spray pattern of evaporimeter is improved, thereby improve evaporation rate greatly.And improve the structure of trapping solution resistance return pipe, make it more be uniformly distributed in the vaporization chamber inwall, quicken double evaporation-cooling.
Solution of the present utility model comprises outer heater and flash evaporation chamber, vaporization chamber is provided with secondary and hinders back distributor pipe and concentrate comb for vapours chuck, indirect steam comb, trapping solution, it is characterized in that being provided with centrifugal atomizer at the vaporization chamber top, by outer heater be heated to boiling point but as yet not the feed liquid of boiling be sprayed into minimum vaporific drop through centrifugal atomizer in that flash evaporation is indoor, thereby moisture is evaporated rapidly.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal sectional view that anxious steaming device is dodged in the traditional vacuum atomizing.
Among the figure, high speed centrifugation atomizer 8 is housed at the top of flash evaporation chamber 4.This centrifugal atomizer mainly is made up of motor 9, centrifugal atomizing dish 2 and feed pipe 11 etc.Outer heater 1 among the figure is a sheath tube heater, and the heater of this structure helps the heated condition of realizing that flash evaporation is required.Feed liquid is heated to normal pressure or pressurization boiling point in this heater after, because this state feed liquid does not down have evaporating space, not explosive evaporation of feed liquid, there is not the variation of concentration in the while yet, so destructive minimum to material.The feed liquid that has been heated to boiling point enters the centrifugal atomizer 8 of rotation at a high speed through feed pipe 11, is sprayed into vaporific group or film in vacuum evaporation chamber 4.Because feed liquid enters the moment pressure of living in of flash evaporator and undergos mutation, the boiling point of feed liquid and gasification latent heat be sudden change thereupon also.This moment, the gasification latent heat of material had decline significantly, was subjected to the compensation heating that secondary is given steam in the thermal jacket 5 again, can make material finish the process of flash evaporation smoothly.The steam liquid foam that generates in the vacuum evaporation chamber 4 is discharged through indirect steam comb 6.Steam is taken out with vavuum pump and is guided to condenser and condense, and condensate liquid is discharged at the bottom of by device.
Mist for flash evaporation is escaped can flow back to flash evaporator again by follow-up mist eliminator after cyclone hydraulic separators hinders back, give thermal evaporation once more.In order to make the solvent or diluent liquid that hinders back be uniformly distributed in the inwall of vaporization chamber 4, it is O shape pipes that the trapping solution of this evaporimeter hinders back distributor pipe 3, arranges along vaporization chamber 4 inwalls, has liquid aperture 12 on it many times, make and hinder back liquid and on the whole inwall of vaporization chamber, form even rete, quicken evaporation.The concentrate finished product is discharged through vaporization chamber bottom comb 7.The steam that generates is extracted out by vavuum pump through secondary steam comb 6.
The characteristics that this vacuum centrifugal atomizing flash evaporator collects centrifugal atomizing, vacuum concentration equipment in One can be sprayed into minimum vaporific drop with feed liquid in flash evaporator, moisture is steamed rapidly Send out, the thermal efficiency has breakthrough raising. Thereby further accelerated the speed of flash evaporation, improve Productivity ratio. The droplet of centrifugal atomizer ejection does not generally contact with the vaporization chamber heating surface, thoroughly The existing easy fouling of various evaporator evaporation faces, wayward, the loss of material of striking point have been overcome Rate increases and the shortcomings such as increase with solute concentration. For the concentrated of heat sensitive material, biochemical product carried Supplied more good equipment.
