Abstract
The utility model discloses a kind of gas distributor for three phase slurry bed bioreactor, comprise gas inlet pipe, described gas inlet pipe is connected with many gas distribution tubes, described gas inlet pipe is used for inputting reaction mixture gas in reactor, described gas distribution tube is for disperseing reacting gas, described gas distribution tube is connected with many gas spray pipes, described gas spray pipe is provided with spray orifice, described spray orifice is positioned at the below of gas distribution tube.This device has the advantages that distribution of gas evenly, not easily occurs to block.
Description
Technical field
The utility model relates to a kind of three phase slurry bed bioreactor, refers to a kind of gas distributor for three phase slurry bed bioreactor especially.
Background technology
Three-phase (gas one liquid one is solid) paste state bed reactor catalyst is dispersed in atent solvent or reaction mass a kind of device carrying out reacting.The stirring carrying out bed owing to adopting reacting gas with mix to reach fully contacting of catalyst and reaction mass, therefore the distribution quality of reacting gas is the key of three phase slurry bed reactor reaction bed success or not.Existing distributor generally adopts porous plate, antipriming pipe, Guan Lie, annular space nozzle, bubble-cap nozzle or katal to levy pore structure, and its air feed part is lower than air jetting holes or contour with air jetting holes.When the slurry material viscosity in slurry bed system is excessive or solid grain size is larger, or interrupt or pressure instability timing at Catalyst packing or the unstripped gas supply of shutting down stage, easily there is the situation such as blocking, slurries adverse current, catalyst or other deposition of solids in distributor, reacting gas is caused to can not get good dispersion, so that the bias current even channel of the bed that reacts, has a strong impact on operation and the operation of slurry bed system.
Summary of the invention
The purpose of this utility model is to provide a kind of distribution of gas that the gas distributor of the three phase slurry bed bioreactor blocked evenly, not easily occurs.
For achieving the above object, the gas distributor for three phase slurry bed bioreactor designed by the utility model, comprise gas inlet pipe, described gas inlet pipe is connected with many gas distribution tubes, described gas inlet pipe is used for inputting reaction mixture gas in reactor, and described gas distribution tube is for disperseing reacting gas.Described gas distribution tube is connected with many gas spray pipes, described gas spray pipe is provided with spray orifice, described spray orifice is positioned at the below of gas distribution tube.In three phase slurry bed bioreactor, spray orifice is always in the bottom of reactor.For ensureing that slurries can not enter gas distributor, also can access high pressure nitrogen arm on gas inlet pipe, passing into high pressure N2 if desired to remove the catalyst or carbon distribution that enter in gas distributor.
As a kind of preferred version, described gas spray pipe is also provided with current-limiting apparatus, for regulating each showerhead gas flow, the distribution of gas that gas distributor is sprayed in three phase slurry bed bioreactor is more reasonable, avoids local air flow excessive or too small.
Alternatively, described current-limiting apparatus is Venturi tube (i.e. large, the middle little tapered pipeline in two ends, aperture), orifice plate or valve.
As a kind of preferred version, described gas spray pipe top is provided with baffle plate, and described gas spray pipe is provided with multiple spray orifice (2 and more than) near baffle plate place.Multiple spray orifice is circumferentially arranged symmetrically with, and spray orifice Way out perpendicular to gas spray pipe axially (spray orifice also can be obliquely opening).
As a kind of preferred version, described gas inlet pipe, gas distribution tube or gas spray pipe are provided with non-return valve.When air feed lost efficacy, non-return valve can block the adverse current of gas, and only when the pressure of slurries is greater than gas pressure in distributor, slurries just can enter distributor.
As a kind of preferred version, many gas distribution tubes adopt concentric circles layout or parallel pipe group layout.When adopting concentric circles layout, each gas distribution tube is the different ring pipe of diameter, is evenly connected on gas inlet pipe; When adopting parallel pipe group layout, each gas distribution tube is the straight tube that length differs, each straight tube closed at both ends and on same circle (this circular diameter is slightly less than reactor bottom diameter), each straight tube is uniformly distributed (also can adjust according to showerhead gas flow).
The beneficial effects of the utility model are: because spray orifice is positioned at the bottommost (except baffle plate) of whole gas distributor, not easily there is deposition and blocking in sparger system, and then improve air feed environment, in addition reacting gas disperses in gas distribution tube, enter pressure distribution after gas spray pipe reasonable, distribution of gas evenly.
