TEMPERATURE AND HUMIDITY CONTROLLABLE EXPERIMENTAL DEVICE FOR MICRON-SIZED PARTICLE TURBULENT FLOW AGGLOMERATION

摘要

A temperature and humidity controllable experimental device for micron-sized particle turbulent flow agglomeration, which belongs to the field of temperature and humidity controllable experimental devices for turbulent flow field collision and agglomeration. The temperature and humidity controllable experimental device for micron-sized particle turbulent flow agglomeration comprises a gas particle generation device, a gas particle mixing and heating device, a turbulent flow collision and agglomeration device, a high-speed camera device, and a gas particle discharge and processing device. Said device can achieve a gas flow rate controlled to be 0.5-20 m/s and a gas flow temperature controlled to be 220-230°C, thereby achieving experimental study work on collision and agglomeration between micron-sized particles under controllable ambient conditions and temperature and humidity conditions, effectively simulating actual industrial processes such as a particle deposition process in a flue gas pipeline, a process of deposition of particles in an electrostatic precipitator reaching a dust collection plate, and dust accumulation on the surface of a heat exchange pipe, and providing effective support for theoretical study on the process of collision and agglomeration between particles.
