Abstract
The invention discloses a non-siphon steam dryer which is substantially composed of a steam admission cylinder cover, a cylinder body, a helical spoiler, a steam baffle, a water outlet impeller cylinder cover and the like. The steam admission cylinder cover and the water outlet impeller cylinder cover are installed at the two ends of the cylinder body. The helical spoiler is installed on the inner wall of the cylinder body. A steam baffle is mounted on the inner wall of the water outlet impeller cylinder cover. When the dryer works in a rotating mode at high speed, the helical spoiler exerts an axial thrust on condensation water on the inner wall of the cylinder body, enables the condensation water to flow to the water outlet impeller cylinder cover and hinders formation of a water ring. Vanes of the water outlet impeller cylinder cover can exert a centripetal acting force on the condensation water on the periphery, and enables the condensation water to be drained out of the cylinder body from an outlet of the water outlet impeller cylinder cover in good time after overcoming the condensation water centrifugal force. The non-siphon steam dryer resolves the two problems that heat transfer efficiency is reduced due to condensation water rings on a high-speed dryer and the condensation water cannot be drained out easily because of the centrifugal force, and various possible dryer operation accidents or explosion accidents caused by siphon faults are eliminated.
Description
Technical field
The present invention relates to steam heat-exchanging drying cylinder equipment, especially a kind of without the siphon pipe steam dryer.
Background technology
At present, the siphon pipe of drying cylinder has fixed and rotary two large classes.All need siphon pipe in time the condensate water in drying cylinder to be discharged to outside cylinder during all steam heat-exchanging type drying cylinder work.The speed different according to drying cylinder, the shape of its condensate water in cylinder body is not identical yet, when drying cylinder speed changes from low to high, the shape of condensate water is respectively the pool in cylinder body bowl-shape → wavy → waterfall shape → water ring shape.For the high speed drying cylinder, must adopt rotary siphon, the condensate water of water ring shape in time could be discharged outside drying cylinder, drying cylinder can be worked on.Adopt rotary siphon, must overcome the centrifugal force that condensate water produces when High Rotation Speed after, could be with condensate water outside water discharge outlet be discharged cylinder body.In drying cylinder, condensate water water ring thickness is thicker, the drainage effect of rotary siphon is just better, but the thermal resistance of water is 80～90 times of the cylinder body thermal resistance, water ring can hinder heating steam the drying cylinder body is conducted heat, and along with the increase of water ring thickness, steam just can reduce rapidly the heat transfer efficiency of drying cylinder, make the outer surface of cylinder block temperature not reach requirement, and the increase of water ring thickness, also increased the heavy burden of drying cylinder, power consumption is increased.The normal method that disturbing flow device is installed that adopts, destroy the bad formation of condensate water water, to keep steam to the heat transfer efficiency of cylinder body at present; Although can play yet disturbing flow device is installed the formation that destruction is condensed water ring, but because the water ring that condenses is destroyed, make again the drainage efficiency of rotary siphon be subject to impact, even normally draining, thus make the overall efficiency of drying cylinder can't improve even accidents caused.Therefore, at present the high speed drying cylinder has and heat transfer efficiency is reduced and discharge difficult two hang-ups because centrifugal force makes condensate water because of the generation water ring that condenses.
