Abstract

It the utility model is related to a kind of catalyst powder grading plant.In order to solve the problems, such as that the fine powder of particle diameter≤22 μm in catalyst prod is not readily separated, there is provided a kind of catalyst powder grading plant.The technical solution of the utility model includes vibratory sieve, is connected with fluid bed, cyclone separator, sack cleaner and air-introduced machine on described vibratory sieve in turn, and fluid bed air blower is also associated with described fluid bed, and described vibratory sieve is single-deck vibrating screen.The utility model disclosure satisfy that the separation of catalyst coarse powder and fine powder simultaneously, and separating effect is splendid, and practicality is relatively broad, improves catalyst product quality and service life.

Description

A kind of catalyst powder grading plant

Technical field

It the utility model is related to a kind of catalyst powder grading plant.

Background technology

Main component is iron oxide in Low Temperature Fischer Tropsch synthesis iron base catalyst product, and average grain diameter is 120 μm, it is desirable to wherein The contents of particle diameter≤250 μm is necessary >=99%, the content of particle diameter≤22 μm it is necessary≤1%.In order to by the coarse powder of particle diameter >=250 μm and The fine powder of particle diameter≤22 μm is separated from finished catalyst, when finished catalyst is sieved using Multilayer vibrating screen, its The coarse powder of middle particle diameter >=250 μm can be kept completely separate, but be difficult to separate for the fine powder vibratory sieve of particle diameter≤22 μm, main cause For：Iron oxide can make catalyst feed produce electrostatic, the less fine powder of particle diameter per se with magnetic, in addition vibratory sieve in vibration Easily it is attached on the larger catalyst granules of particle diameter, is acted on by shaker vibration merely, can not be by fine powder from qualified particle diameter Catalyst in separate, the number of fine powder content, directly influence catalyst product quality and service life.

Utility model content

The utility model is in order to solve the problems, such as that the fine powder of particle diameter≤22 μm in catalyst prod is not readily separated, there is provided a kind of Catalyst powder grading plant.

To solve the problems, such as that prior art is present, the technical solution of the utility model is：A kind of catalyst powder classification dress Put, it is characterised in that：Including vibratory sieve, fluid bed, cyclone separator, sack cleaner are connected with described vibratory sieve in turn And air-introduced machine, fluid bed air blower is also associated with described fluid bed.

Described vibratory sieve is single-deck vibrating screen.

Compared with prior art, it is as follows the advantages of the utility model：

The utility model disclosure satisfy that the separation of catalyst coarse powder and fine powder simultaneously, and separating effect is splendid, and practicality is more Extensively, catalyst product quality and service life are improved.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Description of symbols：1-vibratory sieve, 2-fluid bed, 3-cyclone separator, 4-sack cleaner, 5-fluid bed draw Blower fan, 6-fluid bed air blower.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

Referring to Fig. 1：A kind of catalyst powder grading plant, including vibratory sieve 1, it is connected with turn on described vibratory sieve 1 Fluid bed 2, cyclone separator 3, sack cleaner 4 and air-introduced machine 5, fluid bed air blower is also associated with described fluid bed 2 6, described vibratory sieve 1 is single-deck vibrating screen.

The course of work of the present utility model：Catalyst prod after roasting enters catalyst powder grading plant, enters first Enter in vibratory sieve, the coarse powder of particle diameter >=250 μm in catalyst is gone out using single-deck screen mesh screen, the catalyst for having separated coarse powder enters to become a mandarin Change bed, acted on by fluid bed blower blows and fluid bed induced draft blower withdraws, the fine powder of particle diameter≤22 μm in catalyst is thorough Bottom separates, and separates≤22 μm of fine powder by cyclone separator and sack cleaner separation and reclaims, by≤22 μm urge Agent fine powder is reclaimed, and is focused on, and is gone the air of chalk dust removing to be exported by fluid bed air-introduced machine and is vented.It is qualified after separation Finished catalyst carries out finished catalyst packaging.

The utility model fluid bed makes catalyst prod in fluid bed bed body in fluidisation using fluid bed air blower wind-force State, catalyst of the fine powder under the action of the forces of the wind with qualified particle diameter under fluidized state in catalyst prod can effectively divide From, the fine powder suspension after separation is aspirated in the upper strata of qualified particle size of catalyst, then using fluid bed air-outlet draft fan, according to Make to keep micro-vacuum state in fluid bed by air-introduced machine effect, the fine powder in catalyst prod is carried over fluid bed, by whirlwind Separator separates, and most fine powders is reclaimed, then through sack cleaner dedusting, collect remaining fine powder, focus on.

Because single-layer fluidized bed can not be separated the coarse powder of particle diameter >=250 μm in finished catalyst, therefore, fluidizing Increase single-deck vibrating screen before bed, it is exclusively used in the relatively coarse granule of particle diameter >=250 μm in separating catalyst finished product.

It is described above, preferred embodiment only of the present utility model, it is not intended to limit protection of the present utility model Scope.
