Description
Technical field
The utility model relates to a kind of visor structure, relates in particular to a kind of vertical radial stream molecular sieve top visor structure of uncapping and can measure molecular sieve piling height in the purifier that need not to shut down.
Background technology
Molecular sieve is widely used in empty branch field as the purification plant that air enters before the ice chest, and it is mainly used in moisture in the absorbed air, carbon dioxide, nitrous oxide etc.Traditional molecular sieve is generally horizontal bed structure, but since this kind structure to have floor area big, the pipe arrangement complexity, the oversize distribution of air flow of container is inhomogeneous, be easy to shortcomings such as fluidization, substituted by vertical radial stream molecular sieve day by day for this reason, it is at vertical purifier center a central tube to be set, be used to hold cleaned air passes, central tube is provided with two cylindrical shells outward more with one heart, uniform several long kidney-shaped holes of difference on two cylindrical shells, thereby form ring-type " basket ", in " basket " molecular sieve is housed, air from container outer wall and outside annular space radial flow between " basket " plate to central tube, pass the molecular sieve annular bed that is contained in " basket " therebetween, contained moisture, carbon dioxide etc. are adsorbed.Can upwards not penetrate for fear of carbon dioxide, and then enter central tube after the purification along interior " basket " wall aperture area again, generally prolong the atresia place of safety is set in " basket " top, in the atresia place of safety, also be filled with molecular sieve, molecular sieve in the place of safety also is to participate in adsorption process, therefore the molecular sieve in the place of safety needs regeneration equally, can be owing to regeneration gas comes out upwards to pass through whole place of safety bed height earlier from interior " basket " plate, pass through downwards more whole place of safety bed height from outside " basket " plate go out, the resistance of this process is much larger than the resistance that passes through annular bed, therefore the molecular sieve of place of safety can not get effective regeneration when bed is too high, along with prolong working time, the molecular sieve degradation failure of place of safety, and when bed height is not enough, can't adsorb carbon dioxide all in the adsorption cycle, cause at the carbon dioxide that closes on the cycle end and penetrate bed, the gas concentration lwevel in the central tube exceeds standard, and therefore reasonably bed height could guarantee that air separation unit normally moves.And in actual mechanical process; owing to often be loose condition (of surface) when molecular sieve loads for the first time; density is less, but along with the prolongation of working time, molecular sieve is subjected to the effect of air-flow vibrations and becomes real gradually; density increases; bed height descends gradually, needs in time to replenish molecular sieve this moment and reaches design height, opens the purifier cover plate after therefore existing purifier needs regularly to shut down and measures bed height; not only waste time and energy, and influence production efficiency.
Summary of the invention
The utility model has mainly provided a kind of simple in structure; need not to shut down to uncap and to measure molecular sieve piling height in the purifier; thereby guarantee the vertical radial stream molecular sieve top visor structure of air separation unit operate as normal; solved and opened the purifier cover plate after the need that exist in the prior art are regularly shut down and measure bed height; not only waste time and energy, and influence the technical matters of production efficiency etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of vertical radial stream molecular sieve top visor structure, comprise the purifier top cover, on described purifier top cover, be provided with longitudinal hole, the outboard end of described longitudinal hole is connected with welding neck flange by connecting pipe, described welding neck flange links to each other with the butt joint of cover plate flange, is folded with endoscopy glass between described welding neck flange and cover plate flange.By on the purifier top cover, opening a longitudinal hole; and stretch out at the outboard end of longitudinal hole a connecting pipe is set; can be in the end of connecting pipe grip an endoscopy glass to fetching by welding neck flange and cover plate flange; can guarantee that not only purifier keeps sealing; available again infrared ambulator is irradiation vertically downward above endoscopy glass; molecular sieve surface reflection infrared ray in the purifier; can directly measure the distance on endoscopy glass and molecular sieve surface; it is bed height; wherein extend and be connected the outer connecting pipe of purifier top cover and be convenient to flange and fix; simple in structure; need not to shut down to uncap and to measure molecular sieve piling height in the purifier; thereby guarantee that air separation unit normally moves, convenient to use, enhance productivity.
As preferably, the coaxial base board flange that is provided with between described welding neck flange and cover plate flange, described base board flange is connected on the cover plate flange by securing member, and described endoscopy glass is folded between cover plate flange and base board flange.By between welding neck flange and cover plate flange, base board flange being set, endoscopy glass at first can be clamped between cover plate flange and base board flange and constitute the visor assembly, again the visor assembly is fixed on the welding neck flange, install simple and convenient, the reliability height.
As more preferably, port, bottom surface at described cover plate flange is provided with the cover plate counterbore, end face port in described base board flange is provided with the base plate counterbore, described cover plate counterbore and base plate counterbore one common peripheral are synthesized annular groove, described endoscopy glass is inlaid in the annular groove, and the upper and lower surface of described endoscopy glass respectively and be folded with gasket seal between annular groove.Endoscopy glass is installed in the annular groove that forms between cover plate flange and base board flange, is convenient to the fixed installation of endoscopy glass; Gasket seal is set on the upper and lower surface of endoscopy glass can guarantees to keep between endoscopy glass and flange face sealing.
As more preferably, on the joint face of described welding neck flange and base board flange, be provided with flange gasket.Flange gasket can guarantee that the joint face of welding neck flange and base board flange keeps sealing.
Therefore; vertical radial stream molecular sieve of the present utility model top visor structure has following advantage: by the visor structure is set on the purifier cover plate; can be under the situation of the normal operation of air separation unit; at any time measure the absolute altitude on molecular sieve surface by infrared ambulator through the molecular sieve of endoscopy glass irradiation purifier inside; this measured value is compared with first dress measuring height value again; can learn the falling head of bed; thereby monitored the bed height of molecular sieve in real time; in time replenish molecular sieve when making the bed height of decline surpass setting value again; open the purifier cover plate after need not regularly to shut down and measure bed height; simple in structure, convenient to use.
