Description
Technical field
The utility model belongs to gas-liquid mass transfer in oil refining, the chemical industry equipment, heat transfer technology field; Relate to a kind of mass-and heat-transfer element with structure of film; The three-dimensional mass transfer component that structure of film is all arranged on all surface of gas-liquid contact; This structure of film has played the effect of speed up gas and liquid mass transfer, heat transfer, the distillation, the absorption tower equipment that are particularly suited for refining oil, use in the chemical industry.
Background technology
Invention for the vertical injection mass transfer component of plate column has a lot, for example: combined trapezoid spray tray (ZL01221921.5).But they all are to adopt original primary material (steel plate) to process; The contact surface structure of gas-liquid two-phase of not considering to be processed into element is to the gas-liquid mass transfer Effect on Performance; So the original smooth planar structure when all having adopted steel plate to dispatch from the factory, this has influenced the gas-liquid mass transfer performance of mass transfer component greatly.For the gas-liquid contact surface is the vertical injection mass transfer component of smooth flat structure; Smooth planar structure generally only provides a liquid crushing to become drop; Make drop carrying out drop surface aging in the process of mass transfer, reduced mass transfer, the heat-transfer effect of gas-liquid two-phase with gas.
Summary of the invention
The utility model problem to be solved is; Overcome the deficiency of prior art; A kind of mass-and heat-transfer element with structure of film is provided; The overlay film processing has been carried out on surface to column plate, makes the mass-and heat-transfer element of making have one deck and is beneficial to the structure of film that gas-liquid mass transfer conducts heat, and has improved mass-and heat-transfer efficient.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of mass-and heat-transfer element that provides according to the utility model with structure of film; Comprise column plate, side plate, top board and film, described side plate has four, all around becomes a barrel structure by side plate one, side plate two, side plate three, side plate; Its top is welded with top board, and the bottom is welded on the column plate; Described film is on four blocks of side plates and top board, to be stamped to form with grinding tool, or directly pressing, expand close, seam is on four blocks of side plates and top board.
It is to take following technical scheme further to realize that the utility model solves its technical problem:
The shape of aforesaid film is the figure that has projection or depression, and figure is regular figure or irregular figure, or the combination of regular figure and irregular figure, and the shape area of film is greater than 0 and less than 5cm
2, the height and the degree of depth are greater than 0 and less than 3mm;
The shape of aforesaid film is to have burr on the surface of film; The arrangement of burr is regularly arranged or irregular alignment; Or the combination of rule and irregular alignment, burr length is greater than 0 and less than 3mm, and the angle on the surface of burr and its place film is greater than 0 and less than 180 °;
Aforesaid column plate, side plate, top board are processed by steel plate.
The utility model compared with prior art has significant advantage and beneficial effect:
Because being employed in the surface of column plate, utility model carried out the overlay film processing; Make the mass-and heat-transfer element of making have one deck and be beneficial to the structure of film that gas-liquid mass transfer conducts heat; This membrane structure makes drop in motion process, realize the repeatedly fragmentation and the coalescence of drop, makes the drop surface constantly be in update mode, has improved mass transfer, the driving force of heat transfer of gas-liquid two-phase; Strengthen gas-liquid two-phase mass transfer, heat-transfer effect, thereby improved the mass-and heat-transfer efficient of column plate.
The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

Wherein: 1, column plate, 2, film, 3, the figure of projection or depression, 4, burr, 51, side plate one, 52, side plate two, 53, side plate three, 54, side plate four, 6, top board.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment, structure, characteristic and the effect thereof that provides according to the utility model, specify as after.
A kind of mass-and heat-transfer element shown in Fig. 1～4 with structure of film; Comprise column plate, side plate, top board and film, described side plate has four, surrounds a barrel structure by side plate 1, side plate 2 52, side plate 3 53, side plate 4 54; Its top is welded with top board 6, and the bottom is welded on the column plate 1; Described film 2 is on four blocks of side plates and top board, to be stamped to form with grinding tool, or directly pressing, expand close, seam is on four blocks of side plates and top board.Column plate is processed by steel plate.The shape of film is the figure 3 that has projection or depression; Figure is a regular figure, like triangle, square, rectangle, circle, Long Circle, camber, ellipse, or irregular figure; Or the combination of regular figure and irregular figure, the shape area of film is greater than 0 and less than 5cm
2, the height and the degree of depth are greater than 0 and less than 3mm.The shape of film also can be to have burr 4 on the surface of film; The arrangement of burr is regularly arranged or irregular alignment; Or the combination of rule and irregular alignment, burr length is greater than 0 and less than 3mm, and the angle on the surface of burr and its place film is greater than 0 and less than 180 °.
Operation principle: the utility model is that the gas-liquid contact surface in vertical injection mass transfer unit is covered with skim structure, and this membrane structure can adopt grinding tool to be stamped to form on rapidoprint; Also can be with the direct pressing of prefabricated membrane structure, expand close, seam on former rapidoprint, process composite, be used for the processing of mass transfer unit then.According to the surface renewal theory of mechanism of mass transfer, the gas-liquid contact surface upgrades fast more, and mass transfer, heat-transfer effect are good more.When gas-liquid mixture contacted in the vertical injection mass transfer component of overlay film, under the effect of membrane structure, liquid crushing became drop, realized the maximum contact area of gas-liquid surface; Because membrane structure has been covered with whole mass transfer component; When gas is being carried drop secretly and in mass transfer unit, is being flowed, drop will be under the effect of membrane structure quick fragmentation and coalescence, realize the fast updating on drop surface; Thereby improved mass transfer, the heat-transfer effect of mass transfer unit, improved plate efficiency.
