Abstract
The utility model relates to a fluid distributor and designs a gas phase medium distributor which is used for a triphase pulpous state bed reactor. The utility model is characterized in that the utility model includes an air inlet tube (1), an air ingress pipe (2), an air-guide tube (4), a lacunaris air distribution member (5) and a crash motherboard (3). Compared with prior art, the utility model has the obvious advantages that air speed is controlled by the fluctuation of resistance of the distributor, air in the inner part of the reactor forms a cycle in order to efficiently prevent sedimentation of catalyst and facilitate the catalyst to be evenly and axially distributed in the reactor so as to improve the temperature distribution in the tower, energy loss is low, and upsizing is easy to be achieved.
Description
Technical field
The utility model relates to a kind of fluid distributor, relates in particular to a kind of gas phase media distributor that is used for the three phase slurry bed bioreactor.
Background technology
In the chemical industry field, fluid distributor is a kind of the most common fluid components distributed that is used for, as produce gas or liquid fuel with synthesis gas, usually in the three phase slurry bed bioreactor, in the presence of catalyst, carry out, and enter the state of distribution of the synthesis gas of reactor, the directly efficient of influence reaction.
At present, conventional distributor, the effect that distributes is undesirable, be difficult to produce in the three phase slurry bed of gas or liquid fuel with synthesis gas, therefore, designing a kind of new gas phase media distributor, adopt three phase slurry bed to adapt to, produce the needs of gas or liquid fuel with synthesis gas, is that institute of relevant department is very expected.
Summary of the invention
The utility model technical issues that need to address are to disclose a kind of gas phase media distributor that is used for the three phase slurry bed bioreactor, to overcome the above-mentioned defective that prior art exists.
The said gas phase media distributor that is used for the three phase slurry bed bioreactor of the utility model comprises:
Gas inlet pipe, gas introduction tube, wireway, porous gas allocation member and bump base plate;
Said gas inlet pipe is fixed on the inwall of reactor, and said gas introduction tube is arranged on the downside of gas inlet pipe, and is connected with gas inlet pipe;
One end of said wireway is connected with the porous gas allocation member, have a plurality of downward opening orifices on the said porous gas allocation member, the bump base plate is arranged on the below of porous gas allocation member, inwall with sealing means and reactor fixes, cavity between bump base plate and the porous gas allocation member is the bump chamber, cavity between bump base plate and the gas inlet pipe is the gas buffer chamber, and the other end of wireway passes the bump base plate, is connected with the gas buffer chamber;
Inlet gas enters gas introduction tube by gas inlet pipe, enter the gas buffer chamber then, enter the porous gas allocation member by wireway again, be used for preliminary distribution to gas, by downward opening orifice, at the indoor bump of finishing gas of bump,, upwards enter reactor top then to strengthen mass transfer;
Compared with prior art, remarkable advantage of the present utility model is: control gas speed by the resistance drop of distributor, gas forms interior circulation at inside reactor, can prevent catalyst sedimentation effectively, promote catalyst to improve Temperature Distribution in the tower in that the reactor axial distribution is all even, energy consumption is low, is easy to realize maximizing.
