Energy saving air guide device - kinetic energy recovery air duct

This scheme uses the glass fiber reinforced plastic transformation kinetic energy recovery type air duct, the air duct adopts the new process molding.

Working principle: Ram from bottom to top can be divided into to the fan working period and contraction and the dynamic pressure recovery period of three sections, the flow of air through the countercurrent cooling tower water spray section after the ram is designed according to the elliptic curve to flow contraction, can well uniform shrinkage transition to the fan working segments, airflow in the fan working segments by blade was promoted to the dynamic pressure recovery period of doing work, The dynamic pressure recovery section designed by the theory of equalization of gas flow field is used to guide and diffuse the air flow, and the air flow pressure loss of the exhaust duct is effectively reduced.

Technical features:

Feature 1: high efficiency and energy saving -- compared with the linear natural diffusion type air duct, the air duct eliminates the phenomenon of air flow off the wall, reduces the eddy current area, greatly reduces the area of the air duct center negative pressure area, the air outlet cross-section wind speed distribution tends to be uniform, through the actual application test, the air duct kinetic energy recovery value is more than 30%, energy saving is more than 8%;

Features 2: low resistance -- the inner surface coated with resin twice, after plastic treatment to maintain a higher finish to reduce resistance;

Feature 3: high strength, enhanced design -- the use of trapezoidal large end face hollow reinforcement, stress concentration section and the coupling end of the ring buried in the ring to form a solid ring reinforcement, to ensure the overall strength and operating strength of the air duct, wind load 690Pa;

Feature 4: long life design -- the air duct is connected and fastened with high quality carbon steel, combined with the superior physical and chemical properties of FRP air duct body, so that the air duct is suitable for all-weather outdoor working conditions, under normal conditions, the design service life is not less than 20 years.

Features 5: beautiful and practical - the outer surface of changzhou Tianma Group color gelcoat resin layer containing light stabilizer, so that the air duct has excellent aging resistance, anti direct sun performance, uniform surface color, long use does not fade and crack;
