At present in the auxiliary chemicals charging technology, particularly be dispersed in suspension or solution aid in the viscous liquid, all adopt ball-valve type feeder or reciprocating type plunger feeder, on March 31st, 1999, the Chinese patent ZL 97225598.2 of bulletin provided a kind of automatic catalyst-feeding device, be applicable to that the solids-laden fluid low discharge is reinforced, this feeding device is connected to form by a ball valve and a rotating cylinder, one spherical valve core is housed in the valve body of this ball valve, teflon sleeve is housed in the spool, the horizontal ends of this spherical valve core connects a slide bar with chute, the center of spherical valve core has runs through through hole, and valve body wall is provided with charging aperture and floss hole.Rotating cylinder drives valve core rotation, and moving 90 degree of revolution are just finished charging, reinforced process, and circulation realizes even charging and reinforced, can regulate feeding quantity by regulating rotational frequency.But the poor sealing performance of this feeder, because catalyst enters charge door by gravitational settling, slurries attitude catalyst disperses inhomogeneous, influences reaction speed; Catalyst enters reactor with non-spray pattern simultaneously, causes the reaction gas caking easily.
The utility model content
The purpose of this utility model provides a kind of slurries or liquid catalyst feeding device, realizes the reinforced of slurries or liquid catalyst stable and uniform, accurate quantification.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of slurries attitude or liquid catalyst feeding device, comprise catalyst feed pot, joining microfeeder, hydraulic oil control system and atomizer with it, the microfeeder that it is characterized in that two parallel connections is connected with the catalyst feed pot by pipeline, settle agitator in the feed pot, the catalyst of two microfeeders is provided with valve respectively into and out of pipeline; Pipeline mouth in reactor end is provided with atomizer; Microfeeder is made up of two thorax bodies that elastic diaphragm separates, and wherein oily thorax and hydraulic oil control system connect by the oil circuit feed-line, and catalyst thorax and catalyst turnover feed-line connect; On the oil circuit feed-line between hydraulic oil control system and the microfeeder heterogeneous transfer valve is set.
Catalyst feed pot equipment seals, and agitator adopts the magnetic drives agitator, eliminates the movable sealing of mixing plant, satisfies the ultra-clean requirement of not having leakage and feed pot.The ratio of height to diameter of feed pot is (1.5～3): 1, and agitator can be the anchor formula, also can be the ribbon stirring-cage type, and the rotating speed of general feeder is controlled at 50～200 rev/mins, and its effect provides necessary reinforced buffering and prevents catalyst sedimentation.In order to guarantee pressure stability, can on feed pot, set up pressure control adjusting device.
Heterogeneous transfer valve is alternately to open and close to microfeeder and microfeeder, and valve can adopt check valve, and wherein the valve on the feeding line is the microfeeder inlet valve, and the valve that removes on the material pipeline is the microfeeder bleeder valve.Single spherical sieve tray is set as the elastic diaphragm baffle in the cavity of microfeeder.
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).
