文丘里抽吸式混合加热器的设计

根据文丘里管加速降压原理,设计制作了套管形式的冷热风混合加热器,使风机和燃烧器在正常工作条件下输出设计所需温度参数的热态烟气.该装置解决了烟气脱硫净化等实验研究中热态烟气模拟的难题,具有结构紧凑、热效高、易于调节等特点,可模拟任意一种烟气工况所需的风速和温度参数.

Design of venturi inhaling-mixing heater

According to the operational principle of venturi-tube,a bushing-type heater for mixing hot and cool gaseous flow is designed in order to make the blower and burner exhaust hot smoke with necessary temperature parameter by the design under normal working condition.Using this facility,the problems such as smoke desulphidation and purification have been solved,which are hard to deal with in experimental investigation of hot smoke simulation.This facility possesses features of high thermal efficiency,compact configuration,and liability to be controlled.This facility can be used for simulation of flow velocity and temperature necessary for any kind of smoke conditions.
