Abstract
The utility model belongs to the field of compressed air purifying devices and particularly relates to a diffusion perforated plate of an absorption drier. The diffusion perforated plate of the absorption drier comprises an upper pressure plate, a lower pressure plate and a filter screen, wherein the filter screen is arranged between the upper pressure plate and the lower pressure plate, air holes are formed on the upper pressure plate, and air holes are also formed on the lower pressure plate; and diffusion perforated plates of the absorption drier are arranged at an inlet and an outlet in an adsorption tower respectively, air flows through the small air holes on the lower pressure plate and then is forced to be evenly split, and after flowing through the filter screen, the air is split into more uniform flow bundles and then evenly delivered into an adsorption bed after passing through the upper pressure plates on which the small air holes are formed. The diffusion perforated plate of the absorption drier has a simple structure, is uniform in air distribution, evenly utilizes the adsorptive capacity of desiccant and ensures that the dew point of air is low and stable.
Description
Technical field
The utility model absorption drier diffusion hole plate belongs to the compressed air purifier field, particularly relates to a kind of absorption drier diffusion hole plate.
Background technology
At present, the adsorption tower of general drying machine all is " single-point " inlet and outlet, cause center and peripheral that two a fluid streams are arranged, middle a fluid stream is different with the flow velocity of edge a fluid stream, make large-scale drying tower " short circuit " phenomenon especially severe, when the drier water absorption reached capacity in the middle of causing, the drier at edge also had very big potentiality.Solution to the problems described above is to stack big grain porcelain ball below the drier, improve the uneven phenomenon of flow velocity, but effect is not fine, and flow velocity is still very inhomogeneous.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of dew-point temperature that guarantees that compressed air is good is provided, and air-flow is evenly distributed, and utilizes the absorption drier diffusion hole plate of the adsorption capacity of drier to greatest extent.
The purpose of this utility model reaches by following measure, and the absorption drier diffusion hole plate comprises top board, lower platen, filter screen composition, and filter screen is arranged between top board and the lower platen, and pore is set on top board, and pore is set on lower platen.The absorption drier diffusion hole plate is arranged on import department and the exit in the adsorption tower, and air communication is crossed on the lower platen behind the spilehole, is forced to shunting evenly, after flowing through filter screen, air-flow is divided into how even a fluid stream, after through behind the top board that is abound with spilehole, evenly sent into adsorbent bed.
Filter screen of the present utility model adopts 60 orders.
The utility model is abound with the pore of diameter 30mm on top board, be abound with the pore of diameter 30mm on lower platen.
The utility model is provided with set bolt between top board and lower platen, fixedly filter screen is between top board and lower platen.
The utility model is simple in structure, and air-flow is evenly distributed, and evenly utilizes the adsorption capacity of drier, and the dew point that guarantees to give vent to anger is low and stable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is example structure schematic diagrames of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: lower platen 1, top board 2, filter screen 3, set bolt 4, absorption drier diffusion hole plate 5, adsorption tower 6.
Shown in accompanying drawing 1, accompanying drawing 2, the utility model absorption drier diffusion hole plate comprises top board 2, lower platen 1, filter screen 3 compositions, filter screen is arranged between top board and the lower platen, set bolt 4 is set between top board and lower platen, fixedly filter screen is between top board and lower platen, filter screen adopts 60 orders, is abound with the pore of diameter 30mm on top board, is abound with the pore of diameter 30mm on lower platen.Be assembled into a diffusion hole plate.An absorption drier diffusion hole plate 5 is respectively placed in import department and exit at drying tower 6, thereby guarantee that air-flow can flow through adsorbent uniformly, be abound with aperture on the lower platen 1, after air communication is crossed the pore of lower platen, be forced to shunting evenly, flow through 60 mesh filter screens after, air-flow is divided into how even a fluid stream, after behind the top board of overfill qi-emitting hole, evenly sent into adsorbent bed.
