Embodiment mono-
By accompanying drawing 1-3, can find out that the present invention is that air compressor of locomotive is without hot absorbed air drying machine, comprise 6 adsorption towers 5, described adsorption tower 5 is modular construction, the upper filter set 6 of each adsorption tower 5, locking spring 7, upper location screen pack 8 and gear river 9, location are arranged on the top inner face of adsorption tower 5 tower cylinders, lower combination of filters 3 and axial location gear river 4 are arranged on the lower inner face of adsorption tower 5 tower cylinders, upper filter set 6 and lower combination of filters 3 integrate formation adsorption tower module with cylindrical shell and the sorbing material 11 of adsorption tower 5, 6 adsorption tower modules are divided into two groups and are arranged between a upper cover plate 10 and lower cover 2, by upper cover plate 10, be connected with the two ends of adsorption tower module cylindrical shell respectively with lower cover 2, and utilize upper cover plate 10 and lower cover 2 as air inlet or the outlet passageway of adsorption tower module, the air compressor that is combined to form a modular combination by adsorption tower module and upper cover plate and lower cover is without hot adsorption module type air dryer systems, and carries out without hot absorbed air dry with the formed compressed air of air compressor being discharged without hot absorbed air drying system of this modular combination.Two groups of adsorption tower modules, one group is adsorption tower group, and another group is regenerator group, and two groups is hocket absorption or regeneration operation, and when one group when adsorbing, another organizes the processing of regenerating; One group of adsorption tower module that compressed air is input in two groups is carried out adsorption treatment, the processing of simultaneously regenerating of another group adsorption tower module; After the adsorption tower module absorption of adsorbing is saturated, will switch, by absorption, change the processing of regenerating into, and another group will also be switched, and by regeneration, process and change absorption into.Whole air compressor is arranged on car body by support 13 without hot adsorption module type air dryer systems.
In addition, at lower cover 2, have and change adsorption tower module air inlet or outlet passageway, adsorption tower module is adsorbed or the electrically-controlled valve 1 of the alternately operating of regenerating, the automatic control by electrically-controlled valve 1 is adsorbed or the alternately operating of regenerating adsorption tower module.
Described automatic control is that electric controller is set in electrically-controlled valve, controls electrically-controlled valve carry out conversion process by electric controller; Electric controller carries out SECO as required by a P L C controller 14, and P L C controller adopts FPGA control technology, by the absorption of the control adsorption tower module to the dew-point temperature of outlet side or the switching of recovery time.P L C controller is after accepting the signal of compressor pressure regulator, then the signal of telecommunication of electric pneumatic valve is controlled in output, and by the electric controller of electrically-controlled valve, handles the action of electrically-controlled valve.Under the control of compressor pressure regulator, drying machine workflow is as follows; During compressor start, P L C controller 14 obtains " energising " signal simultaneously.Controller makes electrically-controlled valve 1 one end in " obtaining electric air feed " state, and the electrically-controlled valve other end is in " dead electricity exhaust " state.And handle spool 15 actions with this.When electric pneumatic valve 1 the right in power failure state and the electric pneumatic valve left side in during electricity condition, spool 15 moves to left, open the exhaust passage of B group adsorption tower module, and the exhaust passage of A group adsorption tower module is closed, now, B group tower enters reproduced state.A group tower enters adsorbed state, saturated moist air is entered from admission line after modular five in one air cleaner by air compressor machine, entrained most moisture content in compressed air, oil content and dust are filtered, through air channel, enter inlet valve seat, the intake valve of humid air through opening enters left side drying tower, the flow direction along arrow, behind the air channel of lower cover 2, enter front-seat A group tower arrives behind the exhaust passage that upper cover plate 10 flows through on upper cover plate after absorption, dry air is after drying opened air outlet check valve on upper cover plate 10 by pressure, through gas outlet supply wind devices.And air channel, regeneration hole on the air-out road junction of another road dry wind on upper cover plate 10, enter after rear row B group tower, provide regeneration wind to organize tower desorbed of adsorbed materials, the humid air in B group tower is taken out of to B, the drain tap outlet of the air channel on lower cover 2 and gas control combination valve 1, enters atmosphere through muffler mouth.
When B group tower reproduced state arrives setting-up time, electric controller stops the power supply of the empty threshold of the electricity left side, and at this moment electric pneumatic valve is all in power failure state, and two air bleeding valves are also in closed condition.Therefore A group tower continues absorption, B group tower stops regeneration.The dry air of A group tower is still filled with B group tower in a steady stream, and because B group tower rises pressure without discharge gradually, B group tower is during this period of time in " inflated condition ", and then electric controller starts to the right power supply, and A group tower, B group tower regeneration absorption conversion mutually, complete the change-over period.Per change-over period like this changes the dry and regeneration of left and right drying tower.Like this, left and right drying tower is repeatedly dried and regenerates." inflated condition " makes two tower pressure reduction very low, and induction air flow ratio is slow, reduced widely the impact of charge air flow to drier, therefore be called " flexible conversion ".Flexible conversion has greatly reduced the root of sorbing material generation powder.
