Description
Technical field
The utility model relates to a kind of gas-to-liquid contact film absorptive unit, is particularly useful for membrane absorption method and removes acidity, alkalescence or gas composition such as poisonous, the application of aspect such as also comprise from the liquid degassing or in liquid, inflate.
Background technology
Common gas absorption equipment (like packing tower, liquid column tower and spray column etc.); In the middle of absorption equipment, liquid through grid distributor from top to bottom in tower filling surface evenly flow down, and gas from bottom to top is blown in the tower; By inner-tower filling material, for gas-to-liquid contact provides surface-area.But because gas-liquid two-phase directly contacts in the absorption process, make this technology be subject to the restriction of hydromeehanics conditions such as liquid flooding, channel and entrainment, cause absorbing the liquids and gases skewness, mass-transfer efficiency is low.Though conventional gas absorption technology and equipment have many improvement, purpose is to make and absorbs the tiny increase specific surface of drop, and airflow field is more evenly optimized, and strengthens gas-liquid mass transfer, promotes assimilated efficiency.It is huge that yet its defective is an equipment volume, and technology controlling and process is complicated, and investment and operation expense are high.
The gas-liquid film absorptive unit (membrane contactor) that occurs in recent years can be through hydrophobic hollow-fibre membrane with the gas-liquid two-phase medium separately; Solved the problem that the conventional gas resorber can not make gas phase and liquid phase independent operation; Avoided the appearance of packed tower leakage and channel under high flow rate underflow stream and the low flow velocity; And contact area is big, and mass-transfer efficiency is high.But existing membrane contactor finds to also have a lot of problems to need to be resolved hurrily in actual through engineering approaches application process.
Publication number CN1642628A; The one Chinese patent application that its open day is on July 20th, 2005 discloses a kind of hollow fiber membrane contactors; Use a large amount of thrust-augmenting nozzles and baffle plate to increase the medium flowing homogeneity; Improve mass-transfer efficiency, the two-phase medium flow velocity can change arbitrarily within the specific limits, but the hollow-fibre membrane tow causes gas-phase pressure drop bigger.
Publication number is CN1680006A; The one Chinese patent application that its open day is on October 12nd, 2005 discloses a kind of membrane contactor; Adopt the braiding tubular fibre and be equipped with pipe core improving mass transfer process, but the said tubular membrane contactor of above patent is along with the amplification of its diameter, be easy in the position contraction or expansion of tubular fibre encapsulation casting and break; And the vapour lock that fibrous bundle causes can become along with the increase of gas phase flow greatly, is difficult to realize the application of through engineering approaches.
Publication number is CN1689690; The one Chinese patent application that its open day is on November 2nd, 2005 discloses a kind of hollow fiber membrane contactors; Though but the gas-liquid two-phase medium is an independent operation, the gas phase flow velocity can not be adjusted arbitrarily, because gas phase is to flow in the tubular fibre of at one end shutting all the time.
Publication number is CN101121099A; The one Chinese patent application that its open day is on February 13rd, 2008 discloses a kind of preparation method of hollow fiber membrane contactors; Be to adopt rotary centrifugal force to form the moulding of annular wall after fixing down, need not deviating from this step of casting mould, just can to keep tubular fibre member end be open, though saved the step of form removal, assembling; But when the diameter of membrane contactor becomes big; Because cast is once shaped, require not only that rotary forming equipment is big, prolong set time, more be not easy to dismounting, install and transportation.
Also have following notification number or the pairing technical scheme of publication number (be and announce a few days ago or disclose) with the Chinese patent and the patented claim of hollow fiber bundle formula or column-type film components relevant report: CN2869001Y, CN101007675A, CN2835231Y, CN101254978A, CN201473385U etc.But do not see that bundle formula or pillar hydrophobic hollow fiber membrane module are applied to the patent report of gas-liquid film absorption process at present.Particularly use to the embrane method flue gas desulfurization technique, not only flow is big smoke treatment, and pressure is low, and present being seen film absorptive unit form is difficult to meet the demands.
