Fly ash hollow microsphere pulsation solid-liquid fluidization sorting recovery device and method

Abstract

The invention discloses a fly ash hollow microsphere pulsation solid-liquid fluidization sorting recovery device and method. The device comprises an overflow barrel, an overflow material discharging pump, an overflow opening, a water flow distributor, a water inlet, a first water jacking opening, a second water jacking opening, a first electromagnetic butterfly valve, a first throttle valve, a second throttle valve, a high-level water tank, a sorting bed body, a first internal component, a second internal component, a vertical cylinder, an obconical sleeve, a material inlet, a material inlet pump, a material inlet stirring barrel, a material outlet, a second electromagnetic butterfly valve, a pulsation electromagnetic butterfly valve, an underflow material discharging pump, and an underflow barrel. Through joint action of the pulsation electromagnetic butterfly valve and the underflow material discharging pump, a top-to-bottom pulsation water flow is formed inside the sorting bed body,fly ash magma is sorted by density under the action of the pulsation water flow, and sorted fly ash enters the overflow barrel or the underflow barrel via the material discharging pump, so the sorting recovery operation of hollow microsphere in fly ash is completed. The device is simple, the operation is convenient, and the device can be used for continuous sorting recovery operation of the fly ash hollow microsphere.

Description

technical field [0001] The invention relates to the field of resource processing and utilization of power plant waste fly ash, in particular to a fly ash hollow microbead pulsating liquid-solid fluidized separation and recovery device and method. Background technique [0002] Fly ash is industrial ash discharged from coal-fired power plants. It not only occupies a large amount of land resources for stacking, but also causes serious environmental pollution. Therefore, it is of great significance to carry out comprehensive resource utilization of fly ash. Fly ash hollow microspheres are a new type of multifunctional granular material extracted from fly ash. It has light weight, small particle size, strong wear resistance, high compressive strength, good dispersion fluidity, and , non-toxic and other excellent properties, it can replace the artificial hollow microspheres with high manufacturing cost and be applied to the fields of building materials, rubber, plastics, aerospace...

AI Technical Summary

Problems solved by technology

However, although there are many separation methods for fly ash hollow microspheres, most of the separation processes are cumbersome and the equipment structure is relatively complicated, resulting in low separation recovery and grade of hollow microspheres, which seriously affects the quality of pulverized coal.
