Abstract
The utility model discloses a plate-type falling film evaporator, which can prevent a tail end sheet from being horizontally pushed. The plate-type falling film evaporator comprises a casing; at least one pair of evaporation assemblies are arranged in the casing; each evaporation assembly comprises an evaporation cylinder; a vapor inlet is formed on the outer side of each evaporation cylinder; and the vapor inlet is connected with a vapor entry channel penetrating the casing. By adopting a structure allowing vapor entry from both sides, vapor currents cannot horizontally push the tail end sheet, so as to avoid damages to the tail end sheet. Therefore, the service life of the whole plate-type falling film evaporator is extended.
Description
Technical field
The utility model relates to falling film evaporator, refers more particularly to plate-type down-film evaporator.
Background technology
Plate-type down-film evaporator as shown in Figure 1, present, its structure comprises: cylindrical shell 1; Usually be provided with a pair of evaporative component in the cylindrical shell 1; Each evaporative component comprises an evaporation cylindrical shell 3, also is equipped with admission passage 4 on the described cylindrical shell 1, and a pair of evaporation cylindrical shell 3 is symmetrically distributed in its both sides.In use, when the admission flow velocity reached 40 meter per seconds, this middle road steam admission mode can produce laterally terminal plate and promote, and terminal plate is produced destructive power.In addition, the plate-type down-film evaporator of said structure when plate groups is incorporated into some, because many welding stresses can produce tangible distortion, has influence on the quality of plate-type down-film evaporator, has shortened service life.Therefore, present plate-type down-film evaporator all is middle-size and small-size, in actual application, adopts many cover evaporimeters to accomplish bigger production task jointly, has not only increased equipment investment, and, also need bigger floor space.
The utility model content
The utility model technical problem to be solved is: provide a kind of preventing that terminal plate is produced the plate-type down-film evaporator that laterally promotes.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: plate-type down-film evaporator; Comprise: housing, be provided with at least one pair of evaporative component in the housing, each evaporative component comprises an evaporation cylindrical shell; Arranged outside of each evaporation cylindrical shell has air intake, and air intake links to each other with admission passage in being located in housing.
Angle between the air intake of the evaporation cylindrical shell in the relative in twos evaporative component is 180 degree.
The utility model further technical problem to be solved is: a kind of plate-type down-film evaporator that increases the rigidity after plate makes up is provided.
For solving above-mentioned further technical problem, the technical scheme that the utility model adopts is: be provided with four evaporative components in the described housing, the evaporation cylindrical shell in these four evaporative components is sphere of movements for the elephants shape and arranges.
The beneficial effect of the utility model is: the utility model makes steam flow can not produce laterally terminal plate and promotes, thereby avoid terminal plate is produced destructive power through adopting the double-entry structure, prolonged the service life of whole plate-type down-film evaporator; In addition,, thereby can constitute the less large-scale plate-type down-film evaporator of barrel diameter, increase rigidity, prolong service life through employing sphere of movements for the elephants shape arrangement; Generally, the large-scale plate-type down-film evaporator of separate unit just can satisfy the production needs, has obviously improved space availability ratio, has reduced floor space.

Fig. 4 is the plan structure sketch map of the another kind of embodiment of the said evaporimeter of the utility model.
Among Fig. 1 to Fig. 4: 1, housing, 2, evaporative component, 3, the evaporation cylindrical shell, 4, the admission passage.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
Like Fig. 2, shown in Figure 3; The described plate-type down-film evaporator of the utility model; Comprise: housing 1, be provided with a pair of evaporative component 2 in the housing 1, each evaporative component 2 comprises evaporation cylindrical shell 3; Arranged outside of each evaporation cylindrical shell 3 has air intake, and air intake links to each other with admission passage 4 in being located in housing 1; This is 180 degree to the angle between the air intake of the evaporation cylindrical shell 3 in the evaporative component 2, makes that the admission direction forward of two air intakes is opposite.
As shown in Figure 4, through quadruplet evaporative component 2 is set, and the evaporation cylindrical shell 3 in this quadruplet evaporative component 2 is arranged to be sphere of movements for the elephants shape structure in housing 1, make up large-scale plate-type down-film evaporator.The plate-type down-film evaporator that makes up like this, the diameter of its evaporation cylindrical shell 3 is littler, thereby can do housing 1 littler, and rigidity is stronger.
Claims (3)
1. plate-type down-film evaporator; Comprise: housing is characterized in that: be provided with at least one pair of evaporative component in the described housing, each evaporative component comprises an evaporation cylindrical shell; Arranged outside of each evaporation cylindrical shell has air intake, and air intake links to each other with admission passage in being located in housing.
2. plate-type down-film evaporator as claimed in claim 1 is characterized in that: the angle between the air intake of the evaporation cylindrical shell in the relative in twos evaporative component is 180 degree.
3. according to claim 1 or claim 2 plate-type down-film evaporator, it is characterized in that: be provided with four evaporative components in the described housing, the evaporation cylindrical shell in these four evaporative components is sphere of movements for the elephants shape and arranges.
