The specific embodiment
The antifreeze new wind of the extremely frigid zones rail traffic vehicles air-conditioning system snow defence of the utility model gets into grid and has the comprehensive function that anti-ice and snow, anti-rainwater entering and air cleaning are filtered; Electric heating device is located in the air inlet mozzle; Not only guaranteed the sealed insulation of heater but also satisfied the function that air inlet place ice and snow in time dissolves; Air inlet mozzle mode cross section is designed to the sealed tube of the magnetic tape trailer wing; The employing aluminum alloy mould is shaped, and its long empennage increases area of dissipation, has quickened dissolving of air inlet place ice and snow.The air access path has been optimized in being provided with of empennage, has reduced gas-flow resistance, when the train high-speed cruising, also greatly reduces the noise of air.
Firsts and seconds filter member cross section is designed to c shape structure, and the inside turnup in c shape both sides forms two crystallizing fields, guarantees that dust in air and water droplet accumulate at this, and discharges through the dust exhausting hole of grid bottom.
Ice and snow dissolves the air inlet mozzle, the one-level filter member, and cascade filtration spare divides triplex row to arrange; Pipe fitting is arranged as triangle between per two layers, i.e. one-level filter part is positioned in the middle of the two air inlet mozzles, and secondary filter part is positioned in the middle of the two one-levels filter part; The suction air can not be kept straight on; Have only through fairshaped each layer pipe fitting wall, constantly change traffic direction, make airborne impurity and water droplet get into crystallizing field and discharge outside the car through centrifugal action.
Concrete structure is: these new style grid comprise first filter member, second filter member that is positioned at the intermediate layer that is positioned at the upper strata, the air intake spare that is positioned at lower floor; First filter member, second filter member, air intake spare are the tubular structure of strip; Being provided with of position, the left and right sides, each second filter member is between two first filter member of top, and each air intake spare is between two second filter member of top.
In air intake spare, be provided with the electric tracing line.The cross section of first filter member is the C shape that Open Side Down, is respectively equipped with inside crimping on downward C shape opening both sides.The cross section of second filter member is the C shape that Open Side Down, is respectively equipped with inside crimping on downward C shape opening both sides, is provided with a straight fin at the top of second filter member.The cross section of air intake spare is the tubulose of sealing, and its top is provided with the fin of fin shape.
Action principle: extraneous air is located the Rapid Change of acceleration and direction and is produced very big centrifugal force in the air port of conducting element; Make dust and water droplet contain higher momentum and get into one-level filter part 1 and also slow down with secondary filter part 2; Owing to weight own drops to expansion chamber, get rid of immediately.Because profile is simulated through computer hydrodynamics, therefore when improving filtration, also can reach minimum energy loss and minimum pressure drop.When running into high and cold and during heavy snow weather; Sleet can cover the conducting element surface; Like this grid just the effect through intelligent high temperature electric tracing line make grid surface keep 50 ℃-60 ℃, effectively remove ice and snow in the accumulating of surface, its intelligent companion's hot line can be regulated power automatically with variations in temperature; Be that temperature decline power increases automatically, let the new style grid according to above-mentioned principle operate as normal.
Filter efficiency:Dust is directly proportional with their granular sizes with the filter efficiency of water droplet, is inversely proportional to intake velocity, and normal conditions is following:
A. at water droplet on average greater than 20 μ m, under the situation of face velocity≤3m/s, water droplet filter efficiency>87%.
B. at dust>=60 μ m, under the situation of wind speed≤7m/s, the dust filter efficiency>80%.
C. outer in the winter time Wen Da-40 ℃ extremely frigid zones and severe snow weather also can satisfy instructions for use.
Low energy losses:The filter element profile is through computer hydrodynamics simulation optimization, so energy loss is minimum, and air-pressure drop is minimum.
