AI Technical Summary

Problems solved by technology

Its wall sticking problem has not been completely solved
When the spray flow rate is large enough, the swirl energy will be completely absorbed by the mist beads. As a result, some mist beads and absorbed products cannot get energy to do centrifugal motion, and are naturally discharged with the air flow, which cannot fully separate the absorbent mist beads and The effect of absorbing the product
Secondly, the higher the rotation speed of the pin wheel, the easier it is to stick to the wall

Abstract

The present invention relates to a drying separation equipment, containing tower body, driving device, start-rotating needle wheel, granule sorting device, separating needle wheel and air power separator. It is characterized by that it mainly utilizes the rotor of start-rotating needle wheel to disperse material and start rotational flow, and utilizes the rotational flow to enhance heat condution of material and gas flow, and can force the dried material to make regular centrifugal movement to clean tower wall and eliminate sticky wall phenomenon. The sorting device can be used for collecting the products with different grain sizes or cooling, and the separating needle wheel can raise separation effect. Said invention can implement air flow circularting drying and can raise utilization rate of heat energy.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical drying, and relates to spray dryers, airflow dryers, granulation, evaporation concentration, particle separation and recovery, and gas absorption tower technologies. 2. Background technology [0002] Spray dryers, fluidized bed dryers, airflow dryers, rotary drum dryers, drum dryers, box dryers, vacuum rake dryers, and high frequency dryers are the eight basic drying technology categories . Spray dryers, airflow dryers and fluidized bed dryers are the three categories that develop relatively fast. Among them, the dryers related to the present invention include spray dryers and airflow dryers. The core of the spray dryer is the sprayer, which includes centrifugal atomizer, pressure atomizer and airflow atomizer. [0003] Generally, about 80% of the products of the spray dryer and airflow dryer are collected in the core equipment drying tower, and most of the rest of the products are usually ...
