Abstract

The utility model relates to a waste heat recovery and synergistic device of an engine, comprising a steam-generating box, a steam turbine fan and a condensate tank; an air vent-pipe of the engine passes through the steam generating box; under the action of a water pump, the spray water absorbs the waste heat of the air vent-pipe and turns into the high-pressure steam; the turbine fan rotates under the spraying of the high-pressure steam and transmits a power to the engine in a coaxial connection so as to recover and transfer the waste heat of the exhaust gas into the power of the engine to achieve the goal of the energy saving and the synergic action. By the ventilation cooling of the condensate tank, the steam is turned into the warm water, which is pumped into an air cylinder jacket and then returns back to the steam generating tank for spraying again.

Description

Engine waste heat reclaims enhancing device

(one) technical field

The utility model relates to a kind of engine waste heat and reclaims enhancing device, is a kind ofly to reclaim engine exhaust used heat and it is changed into the device of engine power.

(two) background technique

As everyone knows, in the engine operation process, the energy that fuel combustion discharges removes part and is used to drive work done, overcome outside pumping loss and the internal friction loss, most of form with heat energy is arranged to atmosphere by cooling system, vent systems, and the ratio that really changes into useful work is lower, and thermal loss is more than 60%, not only waste energy, and aggravated environmental pollution.

(three) summary of the invention

The purpose of this utility model provides a kind of engine waste heat and reclaims enhancing device, the kinetic energy that is intended to reclaim the used heat of motor generation and converts it into motor, thus reduce the motor energy consumption, raise the efficiency energy efficiency.

The utility model device comprises steam generating box, steamturbine fan, condensation water tank, the steam generating box that can hold engine exhaust pipe is provided with import and the outlet that outlet pipe is passed in the case, the intake pipe of steam generating box links to each other with the hot high pressure water pump, the inlet tube of hot high pressure water pump be provided with can be matched with the water outlet interface of cylinder chuck link.Steam generating box is provided with a plurality of water intakes, and each water intake is equipped with spraying head.The steamturbine fan contains shell and fin, its rotating shaft master can link to each other with engine crankshaft is coaxial, the steam (vapor) outlet that shell is provided with the steam inlet that communicates with steam generating box and communicates with condensation water tank, be provided with in the condensation water tank heat dissipating pipe and and radiating fin, case can be provided with force ventilated fan outward; The outer pipe of condensation water tank connects warm water pump, and the outer pipe of warm water pump is provided with the link that matches with cylinder chuck water inlet interface;

This device produces high-pressure water vapor by the exhaust waste heat that steam generating box makes the hot water of high-pressure spraying absorb engine exhaust pipe, this water vapor sprays to the turbine fan fin, make its rotation, and by since turbine fan with the coaxial rotating shaft that links to each other of motor energy has been passed to motor.Be condensed after water vapor dispels the heat by condensation water tank and be cooled to warm water, warm water enters the cylinder chuck, absorbs the cylinder wall heat, adds through pump then to be pressed into steam generating box spray outlet pipe generation water vapor, so continuous circulation.

In sum as can be known, the utility model makes water continuous circulation in device draw the heat of engine air casing wall and outlet pipe by the effect of pump, by turbine fan heat energy is changed into mechanical energy, pass to engine crankshaft by rotating shaft at last, reach the purpose that makes engine energy-saving synergy.

(four) description of drawings

Fig. 1 is the structural representation that this engine waste heat reclaims enhancing device.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 represents the schematic representation of motor and steam generating box position relation.

(five) embodiment

Further specify mode of execution of the present utility model below in conjunction with accompanying drawing.Fig. 1 embodiment represents that motor has four outlet pipes 1, this outlet pipe penetrates in the case from the upper end import of steam generating box 10, and pass from the outlet of the lower end of casing, the output pipe 8 of hot high pressure water pump 7 (being the intake pipe of steam generating box) is divided into a plurality of branches and feeds steam generating box 10, and each branch's pipe end is equipped with nozzle 9.Coaxial the linking to each other of bent axle of the rotating shaft 15 of steamturbine fan 12 and motor 16 shown in Figure 2, the steam tube 11 of steam generating box 10 feeds in the housing of turbine fan 12, the steam outlet pipe 13 of turbine fan feeds in the condensation water tank 14, it from the coil pipe type heat dissipating pipe during by (also can be the heat dissipating pipe of the formula of placing side by side or other form) by tube wall and fin radiating and cooling, condensation water tank is outer can be provided with fan 5, quickens the heat radiation process to the heat dissipating pipe blowing of condensation water tank.As shown, the warm water outer pipe 4 of condensation water tank 14 connects warm water pump 13, and the outer pipe of warm water pump 3 is connected with the water inlet interface of link 2 with cylinder chuck 16-3.The hot water suction pipe of hot high pressure water pump 7 is connected with the water outlet interface of link 6 with cylinder chuck 16-3.Under the effect of pump, form circulation waterway between motor chuck 16-3 and this device.Label 16-2 represents the cylinder of motor among Fig. 2, and 16-1 represents the crankcase of motor.Fig. 3 be the B of Fig. 2 to view, the state that the outlet pipe 1 of expression motor 16 passes in the steam generating box 10 of device, visible motor 16 concerns with position between the steam generating box 10.Outlet pipe 1 is cooled off by steam generating box 10, makes waste gas cooling discharging in the pipe.The working principle of this device following (seeing Fig. 2): the warm water after the condensation water tank cooling is sent into by warm water pump 3 and is made the cylinder wall cooling in the motor chuck 16-3, the water intensification is extracted by hot high pressure water pump 7 and is sent into steam generating box 10 in the chuck simultaneously, by outlet pipe 1 spray of spraying head 9 in penetrating case, absorb outlet pipe used heat and become high-pressure water vapor, steam jet is to the fin of turbine fan 12, the rotation of promotion turbine, and the bent axle work done of transmission of power being given motor 16 by rotating shaft 15, the heat energy of engine exhaust used heat has changed into mechanical energy, water vapor feeds in the heat dissipating pipe of condensation water tank 14 then, be cooled to warm water through the ventilation condensation, send back in the motor chuck 16-3 by warm water pump 3, finish once circulation.So constantly carry out repeatedly, make engine waste heat arrive recovery, and make the additional power of the energy of recovery, reduced energy consumption, reach object of energy saving as motor.
