Problems solved by technology

The back-end flue gas has not been processed normally for a long time, and the two flue gas induced draft fans are in direct contact with the kiln exhaust gas, so they can only be used for 2-3 days before the impeller of the induced draft fan needs to be cleaned. The thickening of the adhesive, the cleaning effect is very bad, and the symptoms of impeller dynamic balance failure often appear, and the bearing bush of the fan is also seriously corroded, which has now led to unstable kiln pressure and affected the normal production of the kiln

Embodiment Construction

[0009] Combine below figure 1 , describe in detail the specific details and working conditions proposed by the present invention, figure 1 Among them, the end outlet of the air outlet pipe (2) connected to the fan (1) is connected with an injection port (3), and the injection port (3) is installed in the center of the jet flue (4), and the jet flue (4) is connected to the The lower end of the flue (5) is connected to the kiln tail gas inlet (6), and the tail gas inlet (6) is a kiln (7).

[0010] The present invention works like this, after the high-pressure fan (1) pressurizes the air and injects the air into the jet flue (4) at a high speed through the injection port (3), because the jet flue (4) is a continuously shrinking flue , it forms a negative pressure at the kiln exhaust gas inlet (6) with the air flowing through the high-speed jet, so that the exhaust gas in the kiln (7) is taken out to form a non-contact negative pressure smoke exhaust system, which avoids the The...

Abstract

The invention relates to a jet fan induced wind and smoke exhaust device, which is mainly composed of a fan, an air outlet pipe, an injection port, a jet flue, a flue, a kiln tail gas inlet, and a kiln, and is especially capable of jetting induced air through a high-pressure fan. The non-contact active exhaust of the flue gas from the kiln is carried out, and the exhaust gas of the kiln is discharged from the chimney quickly and efficiently, so as to effectively solve the symptoms of dynamic balance failure of the fan impeller due to the corrosion of residual adhesives and the rust of the bearing bush of the fan. Serious Problem.

Description

Technical field: [0001] The present invention is a jet fan induced wind and smoke exhaust device, in particular, it can carry out non-contact active smoke exhaust for the flue gas of the kiln by means of a high-pressure fan jet induced wind, and quickly and efficiently discharge the kiln tail gas from the chimney, thereby effectively solving the problem of The symptoms of dynamic balance failure of the fan impeller due to the corrosion of residual adhesives and the serious problem of rust of the bearing bush of the fan. Background technique: [0002] The current method of kiln flue gas discharge is to use two flue gas induced draft fans to directly place the kiln flue gas into the chimney for emission. The back-end flue gas has not been processed normally for a long time, and the two flue gas induced draft fans are in direct contact with the kiln exhaust gas, so they can only be used for 2-3 days before the impeller of the induced draft fan needs to be cleaned. The thickeni...
