Ventilation pipe construction As we all know, some ventilation methods should be given priority as technical measures to ensure the air quality of operation and living environment and prevent indoor environmental pollution. Next, spiral Ventilation duct It has a fine seaming forming process. The mold used for its imported equipment is also a special steel structure. Even if it has been used for three or five years, the appearance of its pressing mold will remain unchanged.
When Shenyang ventilation pipeline Before the connection between the air duct and the dust removal equipment, heating equipment, etc., the equipment shall be prefabricated and installed intermittently according to the theoretical mapping drawings after the end of the equipment. When ventilating duct equipment, holes should be opened during air duct prefabrication on air inlet and air outlet days. If it is necessary to open the air outlet on the air duct at the end of the equipment, the interface should be tight. The hose connector can generally use canvas, artificial leather and other information, the hose length should not be less than 200, the tightness should be appropriate, and the flexible hose can buffer the vibration of the fan.
When transporting gas with condensed water or high moisture content, its horizontal pipeline should be set with slope and connected with drainage pipe at the low point. When equipment is used, the bottom of air duct should not have longitudinal joints, and the joints at the bottom should be sealed intermittently. For steel plate air ducts transporting flammable and explosive gases, there should be jumper wires at the connecting flanges of Shenyang ventilation ducts, and they should be connected with the electrostatic grounding grid. When the height of the horizontal air duct is more than 4m, the equipment personnel shall wear safety belts. The springboard on the scaffold or mobile support shall be fixed well, and the width of the springboard shall comply with the safety specifications. The equipment personnel on the scaffold shall carry bags to prevent things or electric drills from falling and hurting people. When the galvanized welded air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet, and the section standard of the soft joint shall be the same as the air inlet and outlet of the fan.
Part of the ventilation of the ventilation pipeline is to use part of the air flow, so that part of the address is not polluted by harmful substances, forming an outstanding air environment. To a large extent, the wind resistance of circular ventilation ducts is much smaller than that of rectangular ventilation ducts; Part of the ventilation system is divided into two categories: partial air supply and partial exhaust. Part of the exhaust air is to capture and purify the pollutants on site and then discharge them to the outside. Part of the air supply is to send the treated and qualified air to some work sites to ensure the air conditions in some areas.
