The hydraulic oil control system is delivered to quantitative hydraulic oil the oil pocket of microfeeder by heterogeneous transfer valve, thereby hydraulic oil promotes the catalyst in the elastic diaphragm promotion catalyst chamber, at this moment, catalyst enters atomizer by check valve, when the microfeeder inner catalyst fans the air, the hydraulic oil release, catalyst enters in the microfeeder catalyst chamber by check valve, quantitative hydraulic oil is delivered in the oil pocket of microfeeder by heterogeneous switch valve simultaneously, the beginning catalyst is reinforced, when the catalyst in the catalyst chamber of microfeeder fans the air, finish once reinforced process, the reinforced of realization continous-stable and accurate measurement switched in circulation.Because catalyst is the slurries attitudes, should be taken into account the settlement issues of solids, general switching cycle is 15～40 minutes.
In order to prevent catalyst poisoning or sex change, must carry with inert gas, jet catalyst, generally select nitrogen for use, atomizer directly upwards is provided with nitrogen inlet, catalyst inlet is set on axially, for guaranteeing atomizing effect, nitrogen inlet is (2～4) with the diameter ratio of catalyst inlet: 1, by regulating the discharge pressure of nitrogen, can realize that the atomizing of different pressures reactor catalyst is added.
The reinforced problem that should consider of catalyst have following some: the addition of catalyst is little, and reinforced scope is big, can be from several milliliters/hours to tens kilograms/hour; The necessary stable and uniform of catalyst feeding quantity, accurate measurement; Catalyst must be continuously, enter reactor with as far as possible little discrete particles degree.
The beneficial effects of the utility model have been to realize that the stable and uniform of slurries or liquid catalyst and accurate measurement are reinforced, and adopt spray atomization technology, guarantee the stability of reaction; This utility model can be applicable to little metered charge (5～10 milliliters/hour) of small test device simultaneously, also applicable to industrial production requirement (40～60 kilograms/hour).
