Abstract
The invention discloses a split-type evaporator which comprises a tubular falling film heater, wherein a raw liquid inlet is arranged at the upper end of the tubular falling film heater, the lower end of the tubular falling film heater is connected with an evaporation tank through a connection pipe, a secondary steam outlet is arranged at the upper end of the evaporation tank, a defoamer is arranged inside the evaporation tank, and an evaporated liquid outlet is arranged at the bottom of the evaporation tank; the evaporation tank is divided into an upper space and a lower space by the defoamer, wherein the lower evaporation space is connected with the lower end of the tubular falling film heater through a connection pipe, and the upper channel space is communicated with the secondary steam outlet. The invention has the advantages that the tubular falling film heater and the evaporation tank are separately arranged, and no clapboard is arranged in the evaporation tank, therefore, an evaporation space ensuring that a vapor-liquid mixture in the evaporation tank generates expansion and decompression and evaporation and a channel space out of which the secondary steam flows are larger relatively, so that the evaporation effect in the evaporation tank and the defoaming effect of the secondary steam are very ideal.
Description
Technical field
The present invention relates to a kind of evaporimeter, relate in particular to a kind of split-type evaporator.
Background technology
Evaporimeter is made up of the two large divisions, and the one, the tube type falling-film heater, its main effect is the medium that heating needs evaporation, makes the temperature of medium reach boiling point and produce evaporation; The 2nd, evaporator, its main effect has two: (1) is that the solution that makes the tube type falling-film heater come out to reach boiling point enters and produces dilatation, decompression behind the evaporator and further violent evaporation, (2) be to carry out vapor-liquid separation, remove the liquid foam of carrying secretly in the indirect steam, not only guaranteed the cleaning of indirect steam but also reduced the loss of effective ingredient.The course of work of evaporimeter is: be evaporated to example with alkali, the alkali lye of being sent here by alkali pump at first is to enter into the tube type falling-film heater, alkali lye inner surface of each root heat exchanger tube in the tube type falling-film heater is membranaceous flowing downward uniformly, alkali lye in flow process and the heating steam of tube side carry out strong heat exchange and obtain rapid temperature raising and reach boiling point and produce evaporation, at this moment the heat exchanger tube center has been full of indirect steam, it can drive the membranaceous alkali lye of inside pipe wall and flow downward at high speed, come out to enter in the evaporator from the tube type falling-film heater base together, the dilatation in evaporator of the alkali lye of boiling point state, decompression and further produce violent evaporation, the indirect steam that evaporator produces is discharged from the indirect steam outlet after removing the liquid foam by the top demister, and the alkali lye after the flash distillation is discharged from the evaporated liquor outlet of evaporator bottom.
As shown in Figure 1, traditional alkali evaporator is an integral structure, its structure mainly comprises: evaporator 1 and the tube type falling-film heater 2 that is arranged on the evaporator 1, be provided with stoste import 3 in the upper end of tube type falling-film heater 2, be respectively arranged with dividing plate 4 and demister 5 in the inside of evaporator 1, dividing plate 4 and demister 5 are divided into two spaces with evaporator, one of them evaporating space and tube type falling-film heater 2 are interconnected, bottom at evaporating space just is provided with evaporated liquor outlet 6 in the bottom of evaporator 1, and the evaporimeter of another channel space is provided with indirect steam outlet 7.The integral type evaporimeter of said structure produces dilatation, decompression in the evaporator and further the evaporating space of evaporation is all relative less with the channel space that indirect steam flows out, so the foam removal effect of evaporation effect and indirect steam is not too desirable in evaporator.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of evaporation effect and foam removal effect all very desirable split-type evaporator.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: split-type evaporator, comprise: the tube type falling-film heater, be provided with the stoste import in the upper end of tube type falling-film heater, the lower end of described tube type falling-film heater is connected with evaporator by tube connector, be provided with the indirect steam outlet in the upper end of evaporator, inside at evaporator is provided with demister, be provided with the evaporated liquor outlet in the bottom of evaporator, demister is divided into two spaces up and down with evaporator, following evaporating space is connected by the lower end of tube connector with the tube type falling-film heater, and top channel space is connected with the indirect steam outlet.
Advantage of the present invention is: the split-type evaporator of this structure, tube type falling-film heater and evaporator branch are arranged, dividing plate is not set in evaporator, further the channel space that flows out of the evaporating space of evaporation and indirect steam is all relatively large so that enter that the liquid-vapor mixture of evaporator produces dilatation, decompression, so the foam removal effect of evaporation effect and indirect steam is all very desirable in evaporator.

Among the figure: 1, evaporator, 2, the tube type falling-film heater, 3, the stoste import, 4, dividing plate, 5, demister, 6, the evaporated liquor outlet, 7, indirect steam outlet, 8, tube type falling-film heater, 9, the stoste import, 10, tube connector, 11, evaporator, 12, indirect steam outlet, 13, demister, 14, the evaporated liquor outlet.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, split-type evaporator, comprise: tube type falling-film heater 8, be provided with stoste import 9 in the upper end of tube type falling-film heater 8, the lower end of described tube type falling-film heater 8 is connected with evaporator 11 by tube connector 10, be provided with indirect steam outlet 12 in the upper end of evaporator 11, be provided with demister 13 in the inside of evaporator 11, be provided with evaporated liquor outlet 14 in the bottom of evaporator 11, demister 13 is divided into two spaces up and down with evaporator 11, following evaporating space is connected by the lower end of tube connector 10 with tube type falling-film heater 8, and top channel space is connected with indirect steam outlet 12.
In 20 ton of 50 alkali vaporization station, use above-mentioned split-type evaporator, during use, carry the alkali lye of coming to enter into tube type falling-film heater 8 by alkali pump by stoste import 9, alkali lye is membranaceous flowing downward uniformly along the inner surface of tube type falling-film heater 8 interior each root heat exchanger tube, alkali lye in flow process and the heating steam of tube side carry out strong heat exchange and obtain rapid temperature raising and reach boiling point and produce evaporation, at this moment the heat exchanger tube center has been full of indirect steam, it can drive the membranaceous alkali lye of inside pipe wall and flow downward at high speed, come out to enter in the evaporator 11 from tube type falling-film heater 8 bottoms together by tube connector 10, the alkali lye of boiling point state is in 11 li dilatations of evaporator, decompression and further produce violent evaporation, the indirect steam that evaporator 11 produces is discharged from the indirect steam outlet 12 of evaporator 11 upper ends after removing the liquid foam by the demister 13 on top, and the alkali lye after the flash distillation is discharged from the evaporated liquor outlet 14 of evaporator 11 bottoms.
The split-type evaporator of said structure, tube type falling-film heater 8 and evaporator were arranged in 11 minutes, dividing plate is not set in evaporator 11, further the channel space that flows out of the evaporating space of evaporation and indirect steam is all relatively large so that enter that the liquid-vapor mixture of evaporator 11 produces dilatation, decompression, so the foam removal effect of evaporation effect and indirect steam is all very desirable in evaporator 11.
