Abstract
The invention discloses a defoaming device of a plate type falling film evaporator capable of enhancing vapor-liquid separation level and improving defoaming effect by rapidly reducing high-speed vapor streams. The defoaming device comprises an outer protective frame and a plurality of mutually parallel baffle plate damping vanes, wherein the plurality of mutually parallel baffle plate damping vanes are arranged in the outer protective frame; defoaming channels are 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 positioned between the inlet section and the outlet section and formed by bending the baffle plate damping vane for a plurality of times; and an exterior angle of the corner of the bent section is provided with an L-shaped fin used for obstructing the flow direction of steam. The invention has the advantages of being capable of rapidly reducing the vapor streams, obviously improving the defoaming effect, enhancing the defoaming efficiency and quality, preventing the effective components contained in secondary steam from being brought out and reducing the production cost.
Description
Technical field
The present invention relates to a kind of plate-type down-film evaporator, relate 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 gets into 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 through 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 through 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, and indirect steam is through the foam removal passage time, and is 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.
Summary of the invention
Technical problem to be solved by this invention 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 scheme that the present invention adopts 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 said 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;
Said bending section is in the shape of the letter V, and corner's angle is 110 ~ 130 degree;
Said bending section is W shape, and corner's angle is 70 ~ 90 degree.
The invention has the beneficial effects as follows: through the structural change of Despumation device, promptly L shaped fin is set, can reduces vapor stream fast at bending section; 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 plate-type down-film evaporator of the present invention;
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 invention in detail.
Like Fig. 1, shown in Figure 2; The Despumation device of plate-type down-film evaporator; Protect frame 1 outside comprising, be arranged on outer some deflection plate damping vanes 2 that are parallel to each other in the frame 1 and the stiffener 3 that is used for fixing some deflection plate damping vanes 2 of protecting; 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, and the place, exterior angle, turning of said bending section 7 is provided with the L shaped fin 8 that is used to hinder steam flow, 2 three bendings of the deflection plate damping vane between inducer 5 and outlet section 6; Form W shape bending section 7, corner's angle is 70 ~ 90 degree.When actual production, also can 2 bendings of the deflection plate damping vane between inducer 5 and outlet section 6 be formed V font bending section 7, 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 invention is: as shown in Figure 1, flow of steam at high temperature gets into foam removal passage 4 from an end of deflection plate damping vane 2 inducers 5, bumps 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 circled round between fin 8 and bending section 7 after touching fin 8;, high speed centrifugation loses speed after separating; The alkali lye foam just is trapped on the deflection plate damping vane 2, just converges in the separation chamber of flowing back to evaporimeter after the alkali lye foam runs up to a certain degree, and the vapor stream after foam removal purifies is discharged from the indirect steam outlet of evaporimeter.
