AI Technical Summary
The crude gas produced by the waste gasification furnace contains components such as tar, dust, moisture, and chlorides, which makes purification difficult. Low-temperature wet purification is inefficient and prone to caking and clogging, affecting the accuracy and efficiency of chemical dosing.
A dosing device was designed, comprising a silo, a heating module, a stirring and arch-breaking device, a feeding mechanism, and a gas-solid mixing module. The device uses steam or electric heating to keep the silo dry, eccentric stirring to prevent material bridging, and multi-stage variable speed nozzles and regulating valves to achieve precise control of gas-solid mixing and dosing.
It achieves precise dosing and flue gas purification of raw fuel gas, solves the problems of high humidity and caking blockage, improves the accuracy and efficiency of dosing, and meets the requirements of ultra-low emissions.
