The specific embodiment
Referring to Fig. 1 and Fig. 2; The automobile-used double tower system of non heated regeneration dryer of a kind of urban rail car and subway, characteristic are that this urban rail car and subway comprise control airduct 1, combination valve 2, lower cover 3, oil water separator 4, adsorbent 5, go up screen pack 6, holddown spring 7, drying tower 8, loam cake 9, wetness 10, electric-controlled box 11 and fire-bar 12 with the double tower system of non heated regeneration dryer;
Be set up in parallel two drying towers 8 between described loam cake 9 and the lower cover 3, and through bolt upper and lower cover and two drying towers connected into integral body, loam cake 9 is provided with the gas outlet and gives vent to anger check-valves; Total reservoir links to each other on gas outlet and the car; The check-valves of giving vent to anger prevents the wind-fall stream of total reservoir, and this loam cake 9 is installed in two drying towers, 8 tops, is provided with oil water separator 4, adsorbent 5 in each drying tower 8, goes up screen pack 6 and holddown spring 7; Promptly the top in drying tower 8 is provided with to give vent to anger and uses screen pack 6; The middle part is provided with adsorbent 5, and the bottom is provided with oil water separator 4, between loam cake 9 and last screen pack 6, holddown spring 7 is set; Be that holddown spring 7 one ends link to each other with loam cake 9, the other end is arranged on the screen pack 6;
Described combination valve 2 is installed on the lower cover 3 and with two drying towers 8 and communicates, and this combination valve 2 is designed to collect air inlet, degassing function is the combination valve of one, in lower cover 3 and combination valve 2 junctions fire-bar 12 is set; Described electric-controlled box 11 is arranged on drying tower 8 fronts between the upper and lower cover, and control airduct 1 couples together electric-controlled box 11 and combination valve 2.Two control magnetic valves, wave filter, circuit board etc. are housed in the electric-controlled box 11, and its function is with the tower work in programme-control two towers, another tower regeneration, two tower alternate cycles; When magnetic valve short circuit occurs, opens circuit, output alarm signal when revealing appears in drier.This drier is provided with wetness 10.Loam cake 9 is a hollow structure.
Adopt bolt with covers and two drying towers linking together tightly, oil water separator is equipped with in the bottom of drying tower, and adsorbent is then loaded at the middle part, the top filter screen of giving vent to anger.Control piper (control airduct) couples together electric-controlled box and combination valve, and fire-bar is contained in lower cover and combination valve junction.This drier is little, light, clever.Easy for installation, easy to maintenance, degree of purification is good, has satisfied the needs of inter-city train, city rail trolley (subway).
The operation principle of the utility model (referring to Fig. 3): this air dryer is the heatless regeneration formula dehumidifying purifier by two drying tower alternations; Left side electrically-controlled valve Ad in electric-controlled box 11 be in electricity condition; And the right electrically-controlled valve Ap is when being in power failure state; Left side intake valve Cd closes, the right intake valve Cp opens, and left side air bleeding valve Bd opens, the right air bleeding valve Bp closes, at this moment; Left side drying tower A1 gets into reproduced state, and the right drying tower A2 gets into adsorbed state.Saturated moist air gets into inlet valve seat by air compressor machine, and humid air gets into the right drying tower A2 through open left side intake valve Cp, along the flow direction of arrow; When passing through the oil water separator 4 of drier bottom; Remove part bigger water droplet, oil droplet and dust, deliver to drying bed then, open the check-valves of giving vent to anger by pressure through dried dry air; Dry air is sent to total reservoir; The left and right sides inlet plenum of check-valves of giving vent to anger has an aperture to link to each other, and drying tower A2 handles through the right purifies air that some flows to left side drying tower A1 through small holes, and drying tower A1 top flows to adsorbent bed from the left side; Take away the moisture (regeneration) in the drying bed, and discharge by air bleeding valve with water droplet, oil droplet and the dust of oil water separator 4 bottoms.
When left side drying tower A1 reproduced state arrived setting-up time, electric controller stopped the power supply to left side electrically-controlled valve Ad, and at this moment (Ad Ap) all is in power failure state to two electrically-controlled valve, and two air bleeding valves also are in closed condition.So the right drying tower A2 continues absorption, and left side drying tower A1 stops regeneration.The dry air of the right drying tower A2 still charges into left side drying tower A1 in a steady stream; Because of left side drying tower A1 has to discharge pressure is risen gradually; Left side drying tower A1 is being in " inflated condition " during this period of time; Electric controller begins the power supply to Ap then, and the change-over period is accomplished in left side drying tower A1, the right drying tower A2 regeneration absorption conversion each other.So each change-over period changes left and right sides drying tower duty, and left and right sides drying tower carries out drying and regeneration repeatedly.
