1. a New-type refuse vehicle conveying arrangement, it is characterized in that, including car body, upper cover plate, connecting rod, hydraulic stem and engine power retracting device, 2 described connecting rod lower ends are hinged on car body, upper end is connected with described upper cover plate, one end of hydraulic stem is connected with one of them connecting rod, and the other end is hinged on car body;

  • This garbage transporting device is driven by electromotor, described engine power retracting device is for reclaiming the heat of motor exhaust, and it includes radiator, electromotor, backwater vaporizer, high temperature heat-exchanging loop, low-temperature heat exchange loop, accumulator battery, inverter and converter, backpressure regulation blower fan;

    Described radiator is connected with electromotor, and radiator leads to supercooled water to be transferred to the heat of electromotor on radiator, and by the surface radiating of radiator;

    The tail gas of electromotor sequentially passes through backpressure regulation blower fan, high-temperature evaporator, cryogenic vaporizer cooling heel row to air;

    High temperature heat-exchanging loop includes high temperature circulation pump, high-temperature evaporator, high temperature multistage expansion turbine and the warm condenser being sequentially connected, in high temperature heat-exchanging loop, the medium of flowing is water, high-temperature evaporator is arranged on the high-temperature tail gas pipeline after backpressure regulation blower fan, the WATER AS FLOW MEDIUM cooled down through warm condenser is squeezed in high-temperature evaporator by high temperature circulation pump, and the WATER AS FLOW MEDIUM after heating subsequently enters the acting of high temperature multistage expansion turbine;

    Low-temperature heat exchange loop includes cold cycle pump, cryogenic vaporizer, intermediate extraction superheater, low temperature multistage decompressor and the low-temperature condenser being sequentially connected, in low-temperature heat exchange loop, the medium of flowing is R245fa, and cryogenic vaporizer is arranged on the low temperature exhaust gas pipeline after high-temperature evaporator;

    Being squeezed in cryogenic vaporizer through the medium R245fa of low-temperature condenser cooling by cold cycle pump, the WATER AS FLOW MEDIUM after heating enters the acting of low temperature multistage decompressor after intermediate extraction superheater heats;

    Intermediate extraction superheater is pipe heat exchanger, and heat source draws gas from the intergrade of high temperature multistage expansion turbine;

    Also include regulating valve, described regulation valve is according to the R245fa Temperature Feedback after intermediate extraction superheater and the pressure feedback in high temperature multistage expansion turbine, for regulating the flow that intergrade is drawn gas, when the R245fa Temperature Feedback value after intermediate extraction superheater is more than or less than the R245fa temperature value after the intermediate extraction superheater set, automatically turn down or open the big aperture regulating valve, simultaneously when the pressure feedback value in high temperature multistage expansion turbine is less than the pressure atresia value in the high temperature multistage expansion turbine set, automatic blocking regulation valve is opened, intergrade after heating is drawn gas and is back to high temperature recuperated cycle loop;

    Distance L between high-temperature evaporator and cryogenic vaporizer is the 3/4 of exhaust pipe road overall length, and high temperature multistage expansion turbine is 3 grades of decompressors, and intergrade is drawn gas and taken from the 2nd grade of high temperature multistage expansion turbine;

    High-temperature evaporator and cryogenic vaporizer all use screen formula-spiral heat exchange tube, and the first half section in gas inlet side uses the screen formula heat exchanger tube being staggered in arrangement, and the second half section uses spiral heat exchange tube;

    Described electromotor is additionally provided with backwater vaporizer on the CWR road of radiator, for reclaiming the heat of engine cooling water backwater, its cooling source takes from the centre tap of cold cycle pump, heated after centre tap R245fa out return to the porch of intermediate extraction superheater;

    Described high-temperature evaporator and cryogenic vaporizer are integrally provided in the heat exchange housing of drum type brake, heat exchange housing is formed by bolt fastening by procapsid and back casing, the length of procapsid is identical with the horizontal length of screen formula heat exchanger tube, and the length of back casing is identical with the horizontal length of spiral heat exchange tube;

    Being provided with multiple vibrator on described screen formula heat exchanger tube, vibrator is powered by accumulator battery;

    The bottom of described procapsid is curved, is additionally provided with sewage draining exit at the minimum point of curved bottom, discharges the dirt fallen that shakes on screen formula heat exchanger tube for periodically;

    Shaft coupling is passed through coaxially connected between low temperature multistage decompressor and high temperature multistage expansion turbine, at the system start-up initial stage, R245fa in low-temperature heat exchange loop arrives vapourizing temperature prior to the water in high temperature heat-exchanging loop, first low temperature multistage decompressor starts, drive high temperature multistage expansion turbine low speed to rotate in advance by shaft coupling simultaneously, play the startup pressure reducing high temperature multistage expansion turbine, shorten the effect of startup time;

    When system stops, the first coasting operation of high temperature multistage expansion turbine is slowed down, and drives low temperature multistage decompressor to slow down by shaft coupling simultaneously, to reduce the idling time of cryogenic expansion machine, plays the air blast friction reducing low temperature multistage decompressor, prevents the effect that blade is overheated;

    Also including that accumulator battery, inverter and converter, one end of high temperature multistage expansion turbine are connected with accumulator battery, accumulator battery is for storing the electric energy being transformed by the kinetic energy of decompressor;

    Accumulator battery is connected with inverter and converter, and inverter is for being alternating current by the DC inverter of accumulator, and converter is used for driving backpressure regulation blower fan and regulating its rotating speed;

    Backpressure regulation blower fan is for lowering and control the back pressure of electromotor, and during operation, the pressure at expulsion feedback by detecting regulates the rotating speed of backpressure regulation blower fan thus regulates back pressure in optimum.
