Description
Technical field
The utility model belongs to catalyst production field, is related to a kind of catalyst fines classification recyclable device.
Background technique
Main component is iron oxide in Low Temperature Fischer Tropsch synthetic catalyst product, and it is powder material that average grain diameter, which is 120 μm,.
Product quality requires the catalyst content that wherein partial size is less than or equal to 44 μm to be necessarily less than equal to 0.2%.In order to improve catalyst
The quality of product, it is necessary to which the fine powder by partial size in catalyst prod less than or equal to 44 μm all removes, to meet or exceed catalysis
Agent product quality indicator.
In process of production, it is isolated by the frequency for adjusting catalyst hierarchy system fluidized bed into, exhaust blower to meet
The requirement of fine powder in catalyst.But when catalyst hierarchy system is adjusted to optimum state, partial size is greater than in the fine powder that is classified out
44 μm of qualified catalyst content still accounts for 20-40% or so, this results in the loss of qualified catalyst prod.
Utility model content
Aiming at the problems existing in the prior art, the utility model provides a kind of catalyst fines classification recyclable device, makes
Qualified catalyst prod is effectively recycled in catalyst fines.
The utility model is to be achieved through the following technical solutions:
A kind of catalyst fines classification recyclable device, including grader, cyclone collector, deduster and air-introduced machine；
The entrance of grader and the outlet of feed system, the upper end fine powder of grader export thin with cyclone collector
The upper end Ultramicro-powder outlet of the connection of powder entrance, cyclone collector is connected to the Ultramicro-powder entrance of deduster, and the gas of deduster goes out
Mouth is connected to the gas access of air-introduced machine.
Preferably, the classifying turbine motor of grader uses Frequency Converter Control.
Preferably, deduster is pulse dust collector.
Preferably, the bottom of grader, cyclone collector and deduster is equipped with discharge port, is respectively provided with and unloads at each discharge port
Expect valve.
Preferably, feed system includes feed bin and batcher, and catalyst fines, into feed bin, then lead to from feed bin entrance blanking
Batcher is crossed to be delivered in grader from the entrance of grader.
Further, batcher is screw(-type) feeder.
Compared with prior art, the utility model has technical effect beneficial below:
The catalyst fines of the utility model are classified recyclable device, using stage turbine in grader high speed rotation and draw
Blower negative pressure wind action, the centripetal force for making catalyst fines not only be subject to centrifugal forces but also generated by air-flow viscous effect
Effect, when being classified the centrifugal force that is subject to of particle and being greater than centripetal force, Cut size require more than coarse fodder, i.e. partial size is greater than 44
μm qualified catalyst be separated, thinner material is brought in cyclone collector and collects, to realize catalyst
Effective recycling of qualified catalyst of the partial size greater than 44 μm in fine powder.It, can will be from cyclone collector by the way that deduster is arranged
Remaining ultrafine dust in gas out is collected by deduster, is further decreased solid content in emptying gas, is subtracted
Few environmental pollution.Annual to recycle qualified 50 tons of finished catalyst or more, economic benefit is considerable.Catalyst is also reduced simultaneously
The solid waste discharge amount of fine powder, reduces environmental pollution, has reached expected purpose.For the classification of same type powder material, recycling wound
Produce a kind of new thinking.
Further, the classifying turbine motor of grader uses Frequency Converter Control, and adjusting frequency converter can adjust impeller
Revolving speed, to obtain varigrained product.
Detailed description of the invention
Fig. 1 is the utility model flow chart.
In figure: 1 is feed bin, and 2 be batcher, and 3 be grader, and 4 be cyclone collector, and 5 be deduster, and 6 be air-introduced machine, 7
It is the second discharge valve for the first discharge valve, 8,9 be third discharge valve.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, it is described be the explanation to the utility model and
It is not to limit.
In order to which partial size is greater than 44 μm of qualified catalyst in recovery of catalyst fines, the loss of catalyst prod is reduced, this
Utility model devises catalyst fines classification recyclable device.
As shown in Figure 1, catalyst fines described in the utility model are classified recyclable device, including grader 3, cyclone collection
Device 4, deduster 5 and air-introduced machine 6, the entrance of grader 3 and the outlet of feed system, the upper end fine powder outlet of grader 3
It is connected to the fine powder entrance of cyclone collector 4, the Ultramicro-powder entrance of upper end the Ultramicro-powder outlet and deduster 5 of cyclone collector 4
Connection, the gas vent of deduster 5 are connected to the gas access of air-introduced machine 6.Grader 3, cyclone collector 4 and deduster 5
Bottom is equipped with discharge port, and the first discharge valve 7, the second discharge valve 8 and third discharge valve 9 are respectively set at discharge port, uses respectively
In the collection of coarse powder, fine powder and Ultramicro-powder.
Feed system includes feed bin 1 and batcher 2, and catalyst fines, into feed bin 1, then pass through from 1 entrance blanking of feed bin
