Description
The utility model relates to and a kind of liquid is carried out the evaporimeter that cryogenic vacuum concentrates.
At present in China, the employed triple effect concentration evaporator of pharmaceutical industry particularly, its agent structure is separate assembling, and this cover unit floor space is big, and each effect (vaporization chamber) all will have independent heater, evaporimeter, steam is recycled three times, will could realize that therefore not only unit is huge through three heaters that separate and evaporimeter, pipeline is numerous and diverse, and waste energy, increase the precious metal consumption.In addition, existing its liquid of evaporimeter is evaporated to static state and soaks tubular type, and tube wall is easily glued by Jiao, makes it to reduce evaporation rate.
In view of the foregoing, the purpose of this utility model provides that a kind of floor space is little, cost is low and is beneficial to the triple effect vacuum concentration evaporator of energy savings.
The purpose of this utility model is achieved in that it comprises a drum shape evaporimeter tank body and moisture trap, discharging conveyer, liquid pump and the solution to be concentrated storage container that links to each other with liquid pump and the hydraulic ejector that vacuumizes usefulness, and its technical characterstic is: be provided with three vaporization chambers in upper, middle and lower that the liquid trap by two bottom band spray apertures is separated in the drum shape evaporimeter tank body; Tank body is provided with outward by the drum shape housing of band charging aperture and discharging opening and the UTILIZATION OF VESIDUAL HEAT IN device that places the coiling formula radiating tube in this housing to constitute; Be provided with a coil heater in three vaporization chambers respectively, three coil heaters are connected in series by pipeline mutually with coiling formula radiating tube in the UTILIZATION OF VESIDUAL HEAT IN device, its air inlet of coil heater that is positioned at vaporization chamber is connected with the vapor outlet port of moisture trap, its each air inlet of coiling formula radiating tube that is arranged in the coil heater of vaporization chamber and following vaporization chamber and UTILIZATION OF VESIDUAL HEAT IN device by pipeline also respectively be positioned at, in, the exhaust outlet of following three vaporization chambers upper end is connected, and the exhaust outlet of coiling formula radiating tube links to each other with hydraulic ejector in the UTILIZATION OF VESIDUAL HEAT IN device; The bottom of the top of last vaporization chamber and following vaporization chamber also is respectively equipped with spray thrower that is connected with the discharging of UTILIZATION OF VESIDUAL HEAT IN device and the coil exchanger that is connected with UTILIZATION OF VESIDUAL HEAT IN device charging aperture, and the charging aperture of this coil exchanger links to each other with the discharging of liquid pump; The liquid collecting funnel of following vaporization chamber inner bottom part is connected with discharging conveyer charging aperture.
The utility model has the advantages that: three vaporization chambers (also claiming triple effect) that will have the split combination now are linked as the upper, middle and lower one, thereby can significantly reduce floor space, both simplified pipeline, and also saved simultaneously the consumption of precious metal such as stainless steel, making it cost greatly reduces; Particularly the steam utilization utilizes the UTILIZATION OF VESIDUAL HEAT IN device that the preheating of soup and the condensation of steam are united two into one often, has greatly saved the energy.In addition, the static state of primary liquid evaporation employing is soaked tubular type change dynamic fountain into, not only can solve the heating tube wall easily by the sticking problem of Jiao, and evaporation rate is accelerated.
Below in conjunction with accompanying drawing the utility model is done ground one step explanation.
Accompanying drawing is a structural representation of the present utility model.
By accompanying drawing as can be known, the utility model comprises a drum shape evaporimeter tank body 2, being flat pyramidal liquid trap 7 by two in this tank body is separated into tank body, in, following three vaporization chambers 3,8,9, the bottom of liquid trap has equally distributed spray apertures 20, be provided with respectively in each vaporization chamber one fall " pyramid " shape coil heater 5 and one by stainless steel wire make every foam net 6, the top of wherein going up vaporization chamber 3 is provided with a spray thrower 4, bottom in the following vaporization chamber 9 is provided with coil exchanger 10, liquid collecting funnel 11, spiral discharging conveyer 12, tank body 2 are outside equipped with is convenient to the moisture trap 1 that is connected with steam boiler and by the band charging aperture, the drum shape housing 14 of discharging opening and the UTILIZATION OF VESIDUAL HEAT IN device of coiling formula radiating tube 15 formations and the hydraulic ejector 18 that vacuumizes usefulness, the liquid pump 16 of transfusion usefulness, the storage container 17 of solution to be concentrated.Coil heater 5 in three vaporization chambers in upper, middle and lower is connected in series mutually with the coiling formula radiating tube 15 in the UTILIZATION OF VESIDUAL HEAT IN device, being arranged in the coil heater of vaporization chamber 8, following vaporization chamber 9 and its each air inlet of coiling formula radiating tube of UTILIZATION OF VESIDUAL HEAT IN device also is connected with the exhaust outlet that is positioned at three vaporization chambers upper ends of upper, middle and lower respectively by pipeline, spray thrower 4 is connected with drum shape housing 14 upper end discharging openings, and coil exchanger 10 is connected with drum shape housing 14 lower end charging apertures.During work, at first open steam valve A, steam is in moisture trap 1 enters coil heater 5, open hydraulic ejector 18 again, make each chamber form vacuum, open bleeder valve C(recirculation control valve B this moment then, cleaning valve D closes) and liquid pump 16, with the soup in the solution to be concentrated storage container 17 through coil exchanger 10, the UTILIZATION OF VESIDUAL HEAT IN device is sent into spray thrower 4, soup is sprayed on the coil heater in the last evaporation tube 3, a soup part that is evaporated becomes secondary steam, under the effect of vacuum gravitation, in the coil heater in the steam vent of last vaporization chamber 3 upper ends is sent in the vaporization chamber 8, the soup that is not evaporated is on the spray apertures 20 of liquid trap 7 bottoms falls to drenching coil heater in the middle vaporization chamber 8 again, residual vapor is converged (under vacuum gravitation) and is entered the coil heater vaporization chamber 8 in in the conduct evaporation thermal source in the vaporization chamber 8 and (will close air bleeding valve E at this moment in the secondary steams that produce in the last vaporization chamber 3 and this indoor coil formula heater, open valve F), with this principle, enter down evaporate in the vaporization chamber 9 after, make the medicine after three evaporation and concentration send into screw feeding conveyer 12 through liquid collecting funnel 11, and in the bucket 13 that connects material outside this conveyer is sent into tank body 2, a working cycles finishes for this reason.Still not ideal enough as the liquor strength after three evaporation and concentration, can discharging, and recirculation control valve B opened, bleeder valve C closes, and carries out the flush distillation circulation again, discharging again when reaching satisfactory liquor strength.The coil exchanger 10 of bottom its role is to utilize the temperature of concentrated medicament to improve the temperature for the treatment of concentrated medicament in the following vaporization chamber 9, reduce self temperature simultaneously, and the effect of UTILIZATION OF VESIDUAL HEAT IN device is to utilize remaining steam heat to improve the temperature of solution to be concentrated, steam self obtains condensation simultaneously, and both common purposes are to utilize to the utmost heat energy.
