Description
The utility model relates to a kind of liquid evaporation concentration equipment, particularly a kind of simple and easy falling film evaporator, and it is a kind of falling film evaporation device, it is applicable to the evaporation in pharmaceuticals industry, food industry, the chemical industry, concentrated and recovery solvent.
It is by heating that evaporation of liquid concentrates, and makes liquid boiling, removes the process of solvent from liquid.The evaporation of liquid concentrator can be divided into atmospheric evaporation, reduction vaporization, thin film evaporation or the like.The main method that normal pressure is accelerated evaporation rate down has following four kinds, and first evaporation of liquid surface area is big more, and evaporation rate is fast more; It two is that vapour concentration is more little on the liquid level, and evaporation rate is fast more; It three is that the difference of hot temperature and liquid boiling temperature is big more, and evaporation rate is fast more; It four is to remove the liquid level conjunctiva and foam also can be accelerated evaporation rate.The mode of thin film evaporation has two kinds: a kind of is to make liquid film flow through heating surface fast to evaporate i.e. falling film evaporation; Another kind is liquid acutely to be seethed with excitement produce a large amount of foams, is that evaporating surface evaporates with the surfaces externally and internally of foam.
The purpose of this utility model is a kind of simple and easy falling film evaporator of design, and it is to utilize the liquid film forming of spray in annular liquid distributor to flow through taper jacketed pan surface fast, and recovery or directly enter in the atmosphere after condensation makes liquid reach concentrated purpose.Because evaporating surface of the present utility model is big, the heated liquid time is short, and the steam on the liquid level is blown off rapidly, so evaporation rate is fast, effective ingredient is destroyed few, is difficult for the pot that overflows, and is difficult for producing coking, gelatinization phenomenon.
The utility model is achieved in that simple and easy falling film evaporator comprises, weak solution container 5, centrifugal pump 6, concentrated solution receiver 8, air blast 10, condenser 11, ventilating fan 12 and duct coupling A, B, C, D, E, wherein weak solution container 5 connects by the import of ring flange and centrifugal pump 6, the port of export of annular liquid distributor 2 by duct coupling A and centrifugal pump 6 that is contained in the taper jacketed pan 3 links, the termination air blast 10 of duct coupling B, the other end is installed on the sidewall of taper jacketed pan 3, the termination duct coupling B of duct coupling D, have wind direction on the another port and turn to and cover 7 and unsettled at the end opening place of taper jacketed pan 3, the end opening of taper jacketed pan 3 connects the end of duct coupling C, another termination concentrated solution receiver 8, the suitable for reading connection by duct coupling E of pot cover 1 receives, arranging device, the end opening of pot cover 1 and the suitable for reading of taper jacketed pan 3 are fixed with screw.
The utility model also can be achieved in that the circular hole that is distributed with 0.5-2mm on the downside of annular liquid distributor 2; What the internal layer of taper jacketed pan 3 adopted is inert, the material of good heat-transfer.
The utility model can also be achieved in that the suitable for reading of pot cover 1 can connect condenser 11 by duct coupling E; Pot cover 1 suitable for reading by the duct coupling E fan 12 that can also run in.
Good effect of the present utility model is:
1, the utility model evaporation rate is fast, and the heated liquid time is short, and the effective ingredient loss is few, is difficult for gelatinization, is difficult for coking.
2, it is simple to the utlity model has manufacturing process, and cost is low, and volume is little, advantage easy to maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure cutaway view of the utility model annular liquid distributor.
Wherein:
1, pot cover 2, annular liquid distributor 3, taper jacketed pan
4, hot water inlet 5, weak solution container 6, centrifugal pump
7, wind direction turn to and cover 8, concentrated solution receiver 9, cooling water outlet
10, air blast 11, condenser 12, ventilating fan
13, returnable A, B, C, D, E-duct coupling
The utility model is described in further detail below in conjunction with accompanying drawing, as shown in Figure 1, 2, when using simple and easy falling film evaporator, determine whether the solvent in the processed weak solution needs to reclaim.Reclaim if desired, the termination pot cover 1 of duct coupling E is suitable for reading so, the import of another termination condenser 11, and the outlet of condenser 11 takes back receptacle 13; If do not need to reclaim, the termination pot cover 1 of duct coupling E is suitable for reading so, the run in import of fan 12 of the other end, and the outlet of ventilating fan 12 is led to outdoor.Hot water inlet 4 connects thermal water source's outlet, and cooling water outlet 9 connects cold water inlet.The course of work of the present utility model is: the valve of opening hot water inlet 4 successively, hot water is entered in the interlayer of taper jacketed pan 3, make interlayer reach uniform temperature, open the valve on the duct coupling A, regulate the feed liquor amount, make solution in the weak solution container 5 through centrifugal pump 6, duct coupling A flows in the annular liquid distributor 2, be distributed with the circular hole of 0.5-2mm on the downside of annular liquid distributor 2, pitch of holes is 5-20mm.The weak solution film forming of spraying in annular liquid distributor 2, the inner surface that flows through taper jacketed pan 3 fast evaporates by heat.The termination duct coupling B of duct coupling D, the another port has wind direction and turns to and cover 7, and unsettled end opening place at taper jacketed pan 3.The wind that air blast 10 blows is through duct coupling B, D, and wind direction turns to and covers 7, and wind direction is upwards blown along the pot wall, and the solvent evaporation is liquid surface after air blast 10 blows off, or is recovered in the returnable 13 after condenser 11 condensations; Or directly enter in the atmosphere through ventilating fan 12, make solution reach concentrated purpose.Regulate the valve on the duct coupling A, can regulate the feed liquor amount, make the strength of fluid that flows in the concentrated solution receiver 8, reach the concentration of regulation.After the solution concentration preparation finished, the valve of closing hot water inlet 4 places was earlier closed centrifugal pump 6 more successively, air blast 10 and ventilating fan 12.
Hot-salt solution can advance to add in hot water inlet 4 places; Also can advance heating steam
