Abstract
Provided is a fluidized bed distributing process used for the classification and the conditioning of coke oven gas flow, the process mainly resolves the problems that single dot distributing is not uniform and has an influence on the fluidization effect. Firstly, raw coal configured in a coal blending shop is transported to a platform disposed on the upper portion of the fluidized bed via a belt conveyor, then the raw coal is transported to a shuttle distributing machine which reciprocates upwards in the width direction of the fluidized bed, and the raw coal is uniformly unloaded into a chute disposed on the upper portion of a feeder of the fluidized bed. The invention changes the original one point receiving of the raw coal used for coking to one line distributing, thereby enabling the feeder of the fluidized bed to distribute uniformly, which remarkably increases the fluidization effect.
Description
Technical field
The present invention relates to the fluidized bed used for coking coal air current grading and conditioning cloth.
Background technology
Coking coal air stream drying technology is at the coke oven coking coal, utilize coke oven flue waste gas, in the nucleus equipment fluidized-bed, coal is carried out classification by granularity requirements, utilize former waste-gas heat to deviate from part moisture in the coal simultaneously, thereby reach the purpose of optimizing the coking coal granularity and adjusting moisture.Because fluidized-bed fluidisation area is big, bed surface is wide, generally adopts the single-point cloth at present, and it is inhomogeneous to produce cloth thus, influences fluid effect.
Summary of the invention
The purpose of this invention is to provide a kind of material distributing method for fluidized bed used for coking coal air current grading and conditioning, this method can make that the fluidized-bed cloth is even, improves fluid effect.
The technical solution adopted for the present invention to solve the technical problems is: at first the raw coal that the coal blending workshop is configured is transported to the fluidized-bed upper brace through conveyor, and be transported to the shuttle-type material distributing machine, the to-and-fro movement on the fluidized-bed width of this material distributing machine is evenly unloaded raw coal to the hopper of fluidized-bed feeding machine top.
In the methods of the invention, be provided with travel switch, control material distributing machine stroke in the material distributing machine bottom.
The invention has the beneficial effects as follows: use raw coal by original some material feedings coking, change a line cloth into, thereby make fluidized-bed feed function uniform distribution.
This method has following characteristics:
1, cloth is even, because material distributing machine adopts the average rate to-and-fro movement, thereby makes the fluidized-bed charging even, can obviously improve fluid effect; Simultaneously form even stock column at the fluidized-bed opening for feed, from playing the effect of material envelope, this is obvious from the effect of opening for feed effusion contaminate environment to preventing waste gas.
2, level of automation height is provided with travel switch in the material distributing machine bottom, and control material distributing machine stroke, equipment move whole employing automatization controls, realizes on-the-spot unattended.
Embodiment
The raw coal that belt feeder configures the coal blending workshop continuously is delivered to the shuttle-type material distributing machine, this material distributing machine is made up of two cover drive units: a cover unidirectional drive distributing belt coal charge is transported in the hopper of fluidized-bed feeding machine top, the one forward and reverse driving cloth trolley of cover to-and-fro movement on the hopper width, thus realized a line cloth.Be provided with travel switch under material distributing machine, control material distributing machine stroke, equipment move whole employing automatization controls, realize on-the-spot unattended.
Shuttle-type material distributing machine of the present invention is a prior art.
Claims (2)
1. material distributing method for fluidized bed used for coking coal air current grading and conditioning, it is characterized in that, at first the raw coal that the coal blending workshop is configured is transported to the fluidized-bed upper brace through conveyor, and be transported to the shuttle-type material distributing machine, the to-and-fro movement on the fluidized-bed width of this material distributing machine is evenly unloaded raw coal to the hopper of fluidized-bed feeding machine top.
2. material distributing method for fluidized bed used for coking coal air current grading and conditioning according to claim 1 is characterized in that, is provided with travel switch in the material distributing machine bottom, with control material distributing machine stroke.
