Title: Intelligent hybrid wet/dry dust removal experimentation system
Inventor: ZHOU GANG
IPC: B01D51/02
Filed: 2019-07-31
Abstract: An intelligent hybrid wet/dry dust removal experimentation system comprises three portions: a dust feeding system, a wet dust removal system, and a dry dust removal system. The dust feeding system provides the system with dust for experimentation. A dust concentration sensor (21) transmits a measured dust concentration value to a computer terminal (29), and then a signal is transmitted to a vibration frequency controller (1) to adjust a dust feeding rate. For the wet dust removal system, dust-laden airflow quickly enters an air inlet (3). Micron-level droplets generated by an ultrasonic atomization nozzle (5) pre-aggregate fine particles in the dust-laden airflow, and the signal is monitored, and then transmitted to the ultrasonic atomization nozzle (5) to adjust an atomization rate. The dust-laden airflow having undergone pre-aggregation undergoes secondary acquisition by means of the dry dust removal system. An operating performance change pattern of a hybrid dry/wet dust removal system is acquired via testing by adjusting parameters such as a filtration speed, a particle size, and a dust concentration.
