Abstract
The invention discloses a defoaming device of a pipe-typed falling film evaporator, and comprises a separation chamber that is arranged at the lower half part of a shell, and a plurality of vapor-liquid separators that are arranged inside the separation chamber and are arranged between the shell and the pipe-typed evaporator; the vapor-liquid separators are uniformly distributed on the periphery of the pipe-typed evaporator, and separate the upper part from the lower part of the separation chamber; the shell of the separation chamber arranged on the upper part of the vapor-liquid separator is provided with a gas discharging port; the vapor-liquid separators are respectively formed by a plurality of curved damping vanes that are paralleled to each other; a defoaming passage is formed between two adjacent damping vanes; the surface of the damping vanes is irregular. The device has the advantages that through changing the structure of the defoaming device, the defoaming effect is obviously improved, the effective compositions in the vapor is prevented from being brought out, the recycling efficiency of the product is improved, and the pollution can be prevented.
Description
Technical field
The present invention relates to a kind of tube-type down-flow evaporator, relate in particular to a kind of Despumation device that is used for the tube-type down-flow evaporator of alumina industry.
Background technology
Despumation device is to be used in the tube-type down-flow evaporator secondary steam is separated and filters, and keeps its passage smooth simultaneously, makes the water of condensation of secondary steam improve the device of cleanliness factor.The Despumation device of existing tube-type down-flow evaporator; Comprise the vapour liquid separator that is arranged between lower housing portion and the tubular evaparator; Vapour liquid separator be distributed in vaporizer around, vapour liquid separator separates the Lower Half and the first half of separate chamber, is positioned on the separation locular wall on vapour liquid separator top to offer the air outlet; Vapour liquid separator is to be arranged by certain form by some damping vanes to form, and can form the foam removal passage between the damping vane.When this Despumation device uses,, generally all be set to about 120 degree because the angle between the damping vane is not quite reasonable; And the surface of damping vane all is smooth; During use, vapour stream is when these damping vanes, and the bump between air-flow and the damping vane is less; Therefore, its foam removal effect is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind ofly can increase air-flow and damping vane bump number of times, improves the Despumation device of the tube-type down-flow evaporator of gas-liquid separation effect.
Further purpose of the present invention is to provide a kind of can more effectively the raising between air-flow and the damping vane to clash into number of times, improves the Despumation device of the tube-type down-flow evaporator of foam removal effect.
For realizing the object of the invention; A kind of Despumation device of tube-type down-flow evaporator; Comprise the separate chamber that is arranged on the housing Lower Half, be arranged in the separate chamber and the some vapour liquid separators between housing and tubular evaparator, some vapour liquid separators be distributed in tubular evaparator around and the top and the bottom of separate chamber be spaced from each other; Be positioned on the housing of separate chamber, vapour liquid separator top and offer the air outlet; Described vapour liquid separator is arranged in a combination after being parallel to each other by the damping vane of some bendings respectively, forms the foam removal passage between the adjacent damping vane, and the surface of damping vane is roughness respectively.
For realizing further purpose of the present invention; A kind of Despumation device of tube-type down-flow evaporator; Also comprise: described damping vane be bent to respectively inlet section, down foam removal section, turn section, go up five sections of foam removal section and outlet sections; Wherein descend interior angle between foam removal section and the last foam removal section to be the angle of 85 to 95 degree, inlet section and outlet section are positioned at same plane, and turn section and inlet section, outlet section are parallel to each other.
Be provided with some concavo-convex skewed slots on the plane of the inlet section of said damping vane, following foam removal section, turn section and last foam removal section.
The invention has the beneficial effects as follows: through the change of scum dredger structure, can obviously improve the foam removal effect, prevent that effective ingredient is taken out of in the steam, and can improve the organic efficiency of product, prevent to pollute.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As illustrated in fig. 1 and 2; The Despumation device of tube-type down-flow evaporator; Comprise the separate chamber 2 that is arranged on housing 1 Lower Half, be arranged in the separate chamber 2 and the some vapour liquid separators 4 between housing 1 and tubular evaparator 3 that some vapour liquid separators 4 are distributed in being spaced from each other of tubular evaparator 3 all around and with the top and the bottom of separate chamber 2; Be positioned on the housing 1 of separate chamber, vapour liquid separator 4 top 2 and offer air outlet 5; Vapour liquid separator 4 is arranged in a combination after being parallel to each other by the damping vane 6 of some bendings respectively, forms foam removal passage 7 between the adjacent damping vane 6, and the surface of damping vane 6 is roughness respectively; This rough damping vane 6 can make the steam flow of the foam removal passage 7 of flowing through flow to and change, and improves the foam removal effect.
As shown in Figure 3; Described damping vane 6 be bent to respectively inlet section 61, down foam removal section 62, turn section 63, go up 65 5 sections of foam removal section 64 and outlet sections; Wherein descend interior angle between foam removal section 62 and the last foam removal section 64 to be the angle of 85 to 95 degree; Inlet section 61 is positioned at same plane with outlet section 65, and turn section 63 is parallel to each other with inlet section 61, outlet section 65.Damping vane 6 be configured to five sections and will descend foam removal section 62 and last foam removal section 64 between angle be set at 85 to 95 the degree; Like this; When steam after getting into by inlet section 61; Vapour stream following foam removal section 62, turn section 63 and on can realize the multiple impact on steam flow and damping vane 6 surfaces in the passage that forms of foam removal section 64, thereby raising foam removal efficient.
In addition, shown in Figure 4 and 5, be provided with some concavo-convex skewed slots 66 on the plane of the inlet section 61 of said damping vane 6, following foam removal section 62, turn section 63 and last foam removal section 64.Being provided with of this skewed slot 66 changes the flow condition of steam steam flow in foam removal passage 7, thereby makes air-flow further increase the bump number of times, and improves the foam removal effect.
