Abstract
The utility model relates to a methanol recovery tower with a flow baffle, and belongs to the field of chemical equipment. The methanol recovery tower with a flow baffle comprises a tower body and a filler layer, and is characterized in that a flow baffle is disposed at the upper part of the filler layer in the tower body. A part of condensate liquid is adhered to the tower inner wall; by using the flow baffle, the liquid does not flow from the tower wall to the tower bottom; after the flow baffle is used, liquid flowing back on the tower wall firstly flows on the flow baffle, and then falls down; because the flow baffle is a circular ring, the liquid is controlled to not flow down along the tower body inner wall at last, but drops from the inner part of the flow baffle circular ring to the filler layer below; therefore the gas liquid phase is balanced, and the recovery efficiency of methanol is increased; the recovered methanol has high purity, and can be recycled; The equipment is simple in structure, low in cost, and convenient for maintenance and service.
Description
Technical field
The utility model relates to a kind of methanol distillation column with flow-stopping plate, belongs to the chemical industry equipment field.
Background technology
Part Chemical Manufacture producer all can use methanol distillation column in process of production at present; Yet the technology of present existing methanol distillation column is not very ripe, and difficulty is very big in operation, and the gas-liquid in the recovery tower is difficult to reach balance mutually; Will cause the organic efficiency of methyl alcohol not high like this; And the methanol purity that reclaims is not high, and water content is excessive, therefore often is that the methyl alcohol that reclaims can not continue to use.
The utility model content
The technical problem that the utility model will solve is: a kind of methanol distillation column with flow-stopping plate is provided, makes gas-liquid phase equilibrium in the recovery tower, Methanol Recovery efficient is high, and the methanol purity of recovery is high.
The utility model solves the technical scheme that its technical problem adopted: a kind of methanol distillation column with flow-stopping plate is provided, comprises tower body and packing layer, it is characterized in that also comprising: the packing layer top in the flow-stopping plate, tower body is provided with flow-stopping plate.
Described flow-stopping plate is an annular.
The diameter of described flow-stopping plate annular and the internal diameter of tower body are complementary.
During use, the first alcohol and water after the gasification is along with rising in the tower body, in the process of rising, and the portion gas condensation; Become liquid, have partial condensation liquid then to be attached on the inner wall of tower, through the use of flow-stopping plate, make that liquid that can not directly flows to tower by the tower wall at the bottom of; After using flow-stopping plate, the liquid that refluxes on the tower wall at first flows on the flow-stopping plate, and then toward falling, because flow-stopping plate is an annular; So control liquid can not flow down along the tower body inwall at last, but is dripped on the following packing layer by the inside of flow-stopping plate annulus, makes gas-liquid reach balance mutually like this; Increased the organic efficiency of methyl alcohol simultaneously, and the methanol purity that is recovered to is high, can recycle.
The beneficial effect of the utility model is: have partial condensation liquid then to be attached on the inner wall of tower, through the use of flow-stopping plate, make that liquid that can not directly flows to tower by the tower wall at the bottom of; After using flow-stopping plate, the liquid that refluxes on the tower wall at first flows on the flow-stopping plate, and then toward falling; Because flow-stopping plate is an annular, can flow down at last so control liquid, but drip on the following packing layer by the inside of flow-stopping plate annulus along the tower body inwall; Make gas-liquid reach balance mutually like this; Increased the organic efficiency of methyl alcohol simultaneously, and the methanol purity that is recovered to is high, can recycle; This device structure is simple, and cost is with low cost, is convenient to care and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
1 is tower body among the figure; 2 is packing layer; 3 is flow-stopping plate.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Of Fig. 1～2, the utility model comprises: tower body 1, packing layer 2 and flow-stopping plate 3, packing layer 2 tops in the tower body 1 are provided with flow-stopping plate 3.
Flow-stopping plate 3 is an annular, and the internal diameter of the diameter of flow-stopping plate 2 annulars and tower body 1 is complementary.
During use, the first alcohol and water after the gasification is along with rising in the tower body 1, in the process of rising, and the portion gas condensation; Become liquid, have partial condensation liquid then to be attached on the inner wall of tower, through the use of flow-stopping plate 3, make that liquid that can not directly flows to tower by the tower wall at the bottom of; After using flow-stopping plate 3, the liquid that refluxes on the tower wall at first flows on the flow-stopping plate 3, and then toward falling, because flow-stopping plate 3 is an annular; So control liquid can not flow down along tower body 1 inwall at last, but is dripped on the following packing layer 2 by the inside of flow-stopping plate 3 annulus, makes gas-liquid reach balance mutually like this; Increased the organic efficiency of methyl alcohol simultaneously, and the methanol purity that is recovered to is high, can recycle.
