Technical field
The utility model relates to moving-burden bed reactor, a kind of specifically continuous catalyst regenerating moving-burden bed reactor.
Background technology
Present hydrocarbon transformation technology is mainly based on fixed bed reactors, and fixed bed reactors claim packed bed reactor again, is filled with solid catalyst or solid reactant in order to realize a kind of reactor of heterogeneous reaction process.Solids is graininess usually, about particle diameter 2～15mm, is piled into the bed of certain altitude (or thickness).The bed transfixion, fluid reacts by bed, and fixed bed reactors are mainly used in the realization gas-solid catalysis, as ammonia convertor, sulfur dioxide contact oxidation device, hydrocarbon steam conversion stove etc.When being used for gas-solid phase or liquid-solid phase uncatalyzed reaction, bed is then loaded solid reactant.The trickle bed reactor also can belong to fixed bed reactors, and the gas, liquid and the flow direction are the contact of gas-liquid solid phase down by bed.The existing fixed bed bioreactor generally has the 1. axial heat-insulating fixed bed reactors of three kinds of forms.The fluid bed of flowing through from top to bottom vertically, bed is with extraneous no heat exchange.2. radial adiabatic formula fixed bed reactors.3. calandria type fixed bed reactor.Constitute by many reaction tube parallel connections.The advantage of fixed bed reactors is: 1. back-mixing is little, and fluid can effectively contact with catalyst, can be than high selectivity when reacting with the series connection side reaction.2. the catalyst mechanical loss is little.3. simple in structure.The shortcoming of fixed bed reactors is: it is poor 1. to conduct heat, when the exothermic heat of reaction amount is very big, even temperature runaway (reaction temperature is out of hand, sharply rises, and surpasses allowed band) also may appear in shell and tube reactor.2. catalyst can not be changed in the operating process, catalyst needs the reaction of frequent regeneration generally should not use, therefore the invention provides a kind of moving-burden bed reactor, can solve fixed bed reactors and have the cyclic regeneration that can't realize catalyst, different shortcomings such as having relatively high expectations of solid particle.
Summary of the invention
The purpose of this utility model is for providing a kind of to catalyst continuous reproducible, treatment effeciency height, the continuous catalyst regenerating moving bed that operating cost is low.
A kind of moving-burden bed reactor of the present utility model is by loading hopper, reactor and regenerator three parts are formed, it is characterized in that reactor top is connected with loading hopper by valve, reactor bottom is connected with regenerator by valve, and the baffle plate control valve is arranged at the bottom of reactor, the gas that responds between reactor bottom and baffle plate control valve inlet, the respond gas outlet of the top of reactor, the regenerated catalyst outlet is arranged at the bottom of regenerator, and the regeneration gas inlet is arranged at the regenerator bottom, and the regeneration gas outlet is arranged at top.
Aforesaid valve can be push-pull valve, ball valve, butterfly valve or stop valve etc.
Aforesaid baffle plate control valve is an overhead gage, lower baffle plate and adjusting knob constitute, overhead gage is connected by adjusting knob with lower baffle plate, the micropore that has the aperture on overhead gage and the lower baffle plate and be 1-2mm can make gas pass through, go up the lower baffle plate macropore that respectively to have two internal diameters be 10-20mm in addition, go up the hole of lower baffle plate when when reaction and stagger to come support catalyst, the macropore of lower baffle plate is exposed make the catalyst whereabouts.
When the baffle plate control valve of opening reactor lower part behind the catalysqt deactivation is discharged the catalyst of inactivation from reactor, the fresh catalyst of opening simultaneously between fresh catalyst and the reactor that valve injects same amount that is connected enters reactor, decaying catalyst is put into regeneration reactor carries out regenerative response by the valve that is connected of reactor and regenerator then.
Advantage of the present invention:
1. simple in structure, cost is lower, and is easy to operate stable.
2. be suitable for the continuous reproduction process of various catalyst
3. this moving bed mainly adopts discharging and the charging that connects valve and manual adjustments catalyst, and less to the wearing and tearing of catalyst, this moving bed is suitable for the regenerative response of the catalyst of various intensity.
4. be connected with valve between feed hopper and the reactor and between reactor and the regenerator, simple to operate.
5. the discharging that the baffle plate control valve comes the manual adjustments catalyst is set in reactor, simple to operate.
6. this reaction unit adopts tandem, can save the space.
