Abstract

The invention provides a multifunctional large draught fan used for a tunnel. The multifunctional large draught fan comprises a ventilation pipeline, a damp-prevention draught fan structure, a draught fan protection net, connecting flanges, a draining groove, an automatic water dispersal device, a water draining pipe and an air filter device. The damp-prevention draught fan structure is mounted on the left side and the right side of the ventilation pipeline, and the connecting flanges are mounted at the left end and the right end of the ventilation pipeline. A draught fan protection net is made of a stainless steel net, the protection effect on fan blades can be improved, and the phenomenon that impurities in the ventilation pipeline collide with the fan blades, and the fan blades are affected is avoided; a metering pump is adopted in a water pump, spraying heads can evenly spray water downwards, dust can be conveniently washed to the bottom of the ventilation pipeline, multiple water spraying heads are arranged, water can be evenly sprayed downwards, use is more convenient, and due to arrangement of an active carbon filter net, a PP cotton filter net and an HEPA filter net, flowing air in the ventilation pipeline can be purified, and during air exchange, the fan is more environment-friendly and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of fans for tunnels, and in particular relates to a multifunctional large fan for tunnels. Background technique [0002] Tunnel fans are widely used in the actual use of water conservancy dam projects, highways, railways, subways and other tunnels. In the long-term use of the tunnel fan, due to the large amount of dust in the environment, the impeller is easy to wear and accumulate dust. In severe cases, the fan will run unbalanced and vibrate greatly, which will cause damage to the fan impeller and cause failure. [0003] However, the existing large fans used in tunnels still have the problems of poor purification effect, more dust and low work efficiency. [0004] Therefore, it seems very necessary to invent a kind of multifunctional large blower fan that is used for the tunnel. Contents of the invention [0005] In order to solve the above technical problems, the present invention provides a multi-fun...
