This invention discloses a high-temperature, high-dust-content
flue gas purification device, relating to the field of
flue gas purification technology. The device includes an adjustable purification structure comprising multiple
ceramic filter elements. SCR catalyst components are coated on the surface of each
ceramic filter element. A swirling
ammonia injection grille is installed at the inlet end of each
ceramic filter element. An attitude adjustment mechanism is connected to the purification structure. A PLC
control system is electrically connected to the attitude adjustment mechanism, which controls the ceramic filter elements of the purification structure to switch between vertical, inclined, and parallel settings. In the vertical setting,
flue gas passes through the
filter element in a straight line from top to bottom or bottom to top. In the inclined setting,
flue gas passes through obliquely, forming a "Z"-shaped path. In the horizontal setting,
flue gas flows laterally through the filter element, and particulate matter is deposited downwards under gravity. This invention solves the problem of low removal efficiency of
fine particulate matter, achieving highly efficient purification of high-temperature, high-dust-content
flue gas, and is particularly suitable for treating high-emission flue gas under complex operating conditions.
