The invention relates to a three-
nozzle offset inclination angle induced air
smoke evacuator, which consists of a fan, an air outlet
pipe, three offset inclination angle jetting heads, a
flue and a
kiln tail gas inlet, wherein the three jetting heads are positioned in a way of forming included angles of 120 degrees with one another, incline at obtuse angles relative to a horizontal plane, and are positioned close to the side of the
flue. Pressurized air is obliquely jetted and induced into the
flue at a high speed by using the high-pressure fan via the three offset jetting heads to form a negative pressure, and three branches of high-speed air flow are mixed with
flue gas in the flue to form spiral rising air flow, so that the blocking effect of a pneumatic turbulent area formed on the lower-middle part of the flue is eliminated basically, non-contact
smoke evacuation is realized, a rapid, efficient, low-consumption and energy-saving
smoke evacuation effect is achieved, and stable running of a
kiln is ensured.
