The defoaming device comprises an outer protection frame and a plurality of baffle plate damping vanes that are parallel to one another and arranged in the outer protection frame, wherein a defoaming channel is formed among the baffle plate damping vanes, each baffle plate damping vane is bent into an inlet section, an outlet section and a bent section which is arranged between the inlet section and the outlet section and formed by bending for multiple times, and an L-shaped fin for hindering flow direction of steam is arranged at an outer angle at a corner of each bent section. The defoaming device has the advantages that the steam flow can be reduced quickly, the defoaming effect can be significantly improved, the defoaming efficiency and the quality can be improved, active ingredients in secondary steam can be prevented from being taken away, and the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of plate-type down-film evaporator, relates in particular to a kind of Despumation device of plate-type down-film evaporator.
Background technology
Plate-type down-film evaporator is widely used in fields such as papermaking, chemical industry.Wherein Despumation device is to be used in the plate-type down-film evaporator indirect steam is separated, and improves the device of indirect steam condensed water cleanliness factor.The Despumation device of plate-type down-film evaporator, operated by rotary motion is in the separation chamber of plate-type evaporator housing Lower Half, and between housing and heat exchanger plates, Despumation device is separated into up and down two parts to the separation chamber, is positioned on the housing wall on top, separation chamber to offer the indirect steam gas outlet.Despumation device is generally formed formation foam removal passage between the adjacent baffle damping vane by protecting deflection plate damping vane that frame, some horizontal direction parallels arrange and the stiffener that is used for fixing the deflection plate damping vane outward.The Despumation device of existing plate-type down-film evaporator, its deflection plate damping vane is set to the V-arrangement bending section, and the angle at V-arrangement angle generally all is set to about 120 degree, and the smooth surface of deflection plate damping vane.In the work, after solution after concentrating enters the lower part of separation chamber, owing to still carry a large amount of heats in the solution, the indirect steam that from solution, volatilizes like this stream between by the deflection plate damping vane just during the foam removal passage and the deflection plate damping vane clash into, make the foam condensing reflux on damping vane in the indirect steam, the higher steam of part cleanliness factor is then smoothly by discharging from the indirect steam gas outlet behind the foam removal passage.Because the Despumation device of existing plate-type evaporator, its deflection plate design is unreasonable, indirect steam is by the foam removal passage time, less with deflection plate damping vane bump number of times, because deflection plate damping vane smooth surface, high velocity vapor stream reduction of speed weak effect, thus cause the foam removal effect relatively poor, and increased production cost.
The utility model content
Technical problem to be solved in the utility model is: can reduce the Despumation device that high velocity vapor stream improves the vapor-liquid separation level, improves the plate-type down-film evaporator of foam removal effect fast thereby provide a kind of.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the Despumation device of plate-type down-film evaporator, protect frame outside comprising, be arranged on the outer some deflection plate damping vanes that are parallel to each other that protect in the frame, form the foam removal passage between this deflection plate damping vane, the deflection plate damping vane is bent to inducer, outlet section and the bending section that bending forms through several times between inducer and outlet section, and the place, exterior angle, turning of described bending section is provided with the L shaped fin that is used to hinder steam flow.
Also comprise the stiffener that is used for fixing some deflection plate damping vanes;
Described bending section is in the shape of the letter V, and corner's angle is 110 ~ 130 degree;
Described bending section is W shape, and corner's angle is 70 ~ 90 degree.
The beneficial effects of the utility model are: by the structural change of Despumation device, promptly at bending section L shaped fin is set, can reduces vapor stream fast, significantly improve the foam removal effect, improve foam removal efficient and quality, prevent that the active ingredient in the indirect steam from being taken out of, reduce production costs.
Description of drawings
Fig. 1 is the structural representation of the Despumation device of the utility model plate-type down-film evaporator;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of deflection plate damping vane.
Among the figure: 1, protect frame outward, 2, the deflection plate damping vane, 3, stiffener, 4, the foam removal passage, 5, inducer, 6, outlet section, 7, bending section, 8, fin.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Fig. 1, shown in Figure 2, the Despumation device of plate-type down-film evaporator, comprise the outer frame 1 that protects, be arranged on the outer stiffener 3 that protects the some deflection plate damping vanes that are parallel to each other 2 in the frame 1 and be used for fixing some deflection plate damping vanes 2,2 of this deflection plate damping vanes form foam removal passage 4, deflection plate damping vane 2 is bent to inducer 5, outlet section 6 and the bending section 7 that bending forms through several times between inducer 5 and outlet section 6, the place, exterior angle, turning of described bending section 7 is provided with the L shaped fin 8 that is used to hinder steam flow, 2 three bendings of deflection plate damping vane between inducer 5 and outlet section 6, form W shape bending section 7, corner's angle is 70 ~ 90 degree.Also 2 bendings of the deflection plate damping vane between inducer 5 and outlet section 6 can be formed V font bending section 7 when actual production, corner's angle is 110 ~ 130 degree; Or will be in more than 2 bending of the deflection plate damping vane between inducer 5 and the outlet section 6.
Operation principle of the present utility model is: as shown in Figure 1, flow of steam at high temperature enters foam removal passage 4 from an end of deflection plate damping vane 2 inducers 5, bump with bending section 7 then, in collision process, form the eddy current vapour group that numerous tiny high speeds are rotated, because bending section 7 corners are provided with fin 8, flow of steam at high temperature is after touching fin 8, between fin 8 and bending section 7, circle round, after separating, high speed centrifugation loses speed, the alkali lye foam just is trapped on the deflection plate damping vane 2, just converge after the alkali lye foam runs up to a certain degree in the separation chamber of flowing back to evaporimeter, the vapor stream after foam removal purifies is discharged from the indirect steam outlet of evaporimeter.
