Ventilation project is an important part of Tianjin HVAC engineering, clean Engineering, fire engineering, environmental protection projects can not be with or lack of. There are a lot of ventilation ducts and ventilation engineering material used, but the most widely used in pipeline ventilation ventilation engineering or the use of galvanized iron duct, central air conditioning engineering, ventilation engineering, constant temperature and humidity purification is most widely applied in engineering.
     The matters needing attention in the installation of the ventilation duct of the Bobei in the ventilation project in Tianjin are as follows:
     (1) when the air duct is connected with the fan, the soft joint should be added in the inlet and outlet, the section size of the soft joint should be consistent with the wind turbine inlet and outlet. Hose connectors generally can be canvas, artificial leather and other materials, hose length should not be less than 200, the tightness should be appropriate, flexible hose can buffer the vibration of the wind turbine.
     (2) when the air duct and dust removal equipment, heating equipment, etc., should be installed before the equipment is installed, according to the actual mapping of the drawings and installation of the installation.
      (3) air duct installation, into and out of the open hole in the air duct should be prefabricated, if installed in the air duct on the open air, the interface should be tight.
     (4) the horizontal pipe should be provided with a slope, and the drainage pipe should be connected to the low point when the conveying water containing condensed water or a large amount of wet gas. When installing, the bottom of the air duct should not be provided with longitudinal joints, and the joints at the bottom should be sealed.
      (5) to transport flammable and explosive gas in the air duct, in the air duct connection flange connection should be installed, and the connection with electrostatic grounding grid.
     (6) when the height of the horizontal air duct is above 2m, the installation personnel should wear the safety belt. A scaffold or movable bracket shall be fixed, a width should comply with safety regulations, installation personnel on the scaffold should carry tool bag, or drill tools to prevent falling wounding etc..
      (7) after the air duct is in place, the double boom bracket should ensure that the cross arm is straight and the hanger rod is not twisted.
        In the installation of ventilation ducts in the installation of the installation of the site should continue to use the above provisions.
