Abstract
The utility model relates to an adjustable compressed air film drying pipe which belongs to the technical field of pneumatic equipment. The adjustable compressed air film drying pipe is characterized in that both ends of a bunch of hollow fibre film are encapsulated in a plastic or metal casing body; and the metal casing body of the air production end is provided with an air sweeping hole. Compared with the traditional methods of cryogenic freezing, molecular sieve adsorption, salt adsorption, and the like, the utility model has the advantages of simple operation, convenient use, non-maintenance, no pollution, and the like, the dehumidifying drying effect of the air is good at the same time, and the dew point (drying degree) of product gases is adjustable.
Description
Technical field
The utility model belongs to the pneumatic equipment technical field.
Background technology
In a lot of pneumatic equipments, need dry gas, and for present air dehumidification dry technology, what generally use is methods such as cryogenic freezing, molecular sieve adsorption, salt absorption, these methods often exist complexity simple to operate, it is inconvenient, difficult in maintenance to use and have problem such as pollution arranged.
Summary of the invention
The purpose of this utility model is:
A kind of adjustable compressed air film drying tube is provided, and it utilizes the embrane method dehumidification and purges the air-flow principle, has solved the dry problem of air dehumidification effectively.
The technical solution of the utility model is:
A branch of hollow-fibre membrane two ends are encapsulated in plastics or the metal shell, on the metal shell of aerogenesis end, are provided with the purging pore.
The inner chamber of every hollow-fibre membrane is less than 1 millimeter.
Establish one at purging pore place and be used to regulate the cone valve that purges air-flow.
The beneficial effects of the utility model are:
Compare with methods such as traditional cryogenic freezing, molecular sieve adsorption, salt absorptions, have advantages such as simple to operate, easy to use, non-maintaining, pollution-free, air dehumidification drying effect is good simultaneously, and the dew point of product gas (degree of drying) is adjustable.
Description of drawings
Fig. 1 is the utility model structure chart.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the 1st, air inlet, the 2nd, doughnut, the 3rd, aerogenesis mouth, the 4th purges pore, the 5th, steam vent, the 6th, sweep gas control valve, the 7th, housing.
Adopt the diffusion barrier of the hollow-fibre membrane of macromolecular material preparation as the compressed air dehumidification.In the film drying tube of present technique, compressed air is told the reverse purging doughnut of a part of dry air outer wall (walking shell side) by the inner chamber (walking tube side) of doughnut, by the empty emptying of exhaust.
Containing wet compressed air is entered by the air inlet (1) of drying tube, by hollow-fibre membrane (2) inner chamber, institute's containing water vapor sees through the doughnut membranous wall to the outside, the compressed air of residue drying is used by the aerogenesis mouth (3) of drying tube, draw the sub-fraction dried compressed air and enter housing by purging pore (4), the steam that purging doughnut outer surface will see through is taken away, by steam vent (5) emptying.
Usually the sweep gas hole dimension of film drying tube is fixed, the dew point of product gas (degree of drying) is also fixed under certain temperature and operating pressure, for example the technical indicator of certain model film drying tube is: 20 ℃ of intake air temperature, operating pressure 0.8Mpa, during sweep gas ratio 20%, product gas atmospheric pressure dew point reaches below-20 ℃, but the user who has does not need the air below the dew point-20 ℃, perhaps product gas dew point reaches-10 ℃ and just can use, obvious 20% sweep gas has flow through greatly, causes the wasting of resources; The user who has wishes to obtain the product gas of lower dew point and does not mind the size that purges air-flow, obviously should increase to purge air-flow to obtain the product gas of lower dew point.
Regulate the size that purges air-flow by sweep gas control valve (6), can regulate the dew point of product gas within the specific limits, also can change and cause and regulate the sweep gas flow when purging variations in flow, satisfy the needs of different user at operating pressure.
