Abstract
The invention discloses an enthalpy wheel, which is arranged between the air outlet of an air compressor and the air outlet of an electric pile. The enthalpy wheel comprises a horizontal outer barrel, end plates, an enthalpy wheel shaft, a ceramic core and an air driving mechanism, wherein the end plates are arranged at the two ends of the outer barrel respectively; the enthalpy wheel shaft penetrates through the two ends of the outer barrel along a shaft line of the outer barrel; the ceramic core is arranged in the outer barrel and sleeved on the enthalpy wheel shaft; the air driving mechanism is opposite to the air outlet of the air compressor or/and the air outlet of the electric pile; and the air driving mechanism is fixedly connected with the end plates and also connected with the end part of the enthalpy wheel shaft. As a driving motor is not required, the enthalpy wheel is compact in structure, space-saving and low in weight, and does not need to be driven by external power, so that the energy of a power system of a carrying tool is reduced.
Description
Technical field
The present invention relates to the PEM fuel cell engine technology, more particularly, relate to a kind of enthalpy wheel for car and boat Proton Exchange Membrane Fuel Cells dynamical system.
Background technology
The Proton Exchange Membrane Fuel Cells dynamical system is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), and it is directly changed into electric energy by electrochemical reaction with the chemical energy in fuel (normally hydrogen or methyl alcohol).Compare with traditional Blast Furnace Top Gas Recovery Turbine Unit (TRT), its power generation process does not relate to oxyhydrogen combustion, is not subjected to the restriction of Carnot cycle, and product is water, therefore, has efficient high, the advantages such as zero pollution.
In Proton Exchange Membrane Fuel Cells, in order to prevent fuel battery proton exchange film dehydration under load condition, need to use air modifier and be the enthalpy wheel, the enthalpy wheel is that a kind of moisture in the waste gas that fuel cell power system discharges and heat of utilizing is to the device of the gas humidification that enters fuel cell.This device needs motor-driven, at present, car, marine fuel cell power systems enthalpy wheel generally adopt motor to drive, as shown in Figure 1, in figure, 11 is that reducing motor, 12 is enthalpy wheel body, its advantage is that motor-driven is stable, but weak point is: 1) motor takies a part of space, and enthalpy wheel volume is increased; 2) the motor own wt increases enthalpy wheel overall weight; 3) motor operation consumption systems energy.
Summary of the invention
For the defective that exists in prior art, the purpose of this invention is to provide a kind of enthalpy wheel.
For achieving the above object, the present invention adopts following technical scheme:
A kind of enthalpy wheel, be located between the air outlet of the air outlet of air compressor machine and pile, comprise horizontally disposed urceolus, end plate, enthalpy wheel shaft, ceramic core and gas-powered mechanism, described end plate is located at respectively the two ends of urceolus, described enthalpy wheel shaft runs through the two ends of urceolus along the axis of urceolus, described ceramic core is located in urceolus and is set on the enthalpy wheel shaft; The air outlet of described gas-powered mechanism and air compressor machine is or/and the air outlet position of pile is relative, and described gas-powered mechanism is fixedly connected with end plate, and gas-powered mechanism also is connected with the end of enthalpy wheel shaft.
Described gas-powered mechanism comprises gas hood, impeller, gear and pipe joint, the end of described impeller, gear and enthalpy wheel shaft is located in gas hood, the air inlet of described gas hood is over against the air-out of air compressor machine or/and the moisture delivery outlet of pile, described gear comprises driving gear and driven gear, described impeller and driving gear rigid attachment, the end key connecting of described driven gear and enthalpy wheel shaft, described impeller is corresponding with the position of gas hood air inlet; Described pipe joint is located on the end plate of the other end corresponding with gas hood.

Fig. 2 is the structural representation of a kind of enthalpy wheel of the present invention;
Fig. 3 is the cross sectional representation of ceramic core in Fig. 2.
Embodiment
Further illustrate technical scheme of the present invention below in conjunction with drawings and Examples.
See also a kind of enthalpy wheel shown in Figure 2, be located between the air outlet of the air outlet of air compressor machine and pile, comprise horizontally disposed urceolus 5, end plate 4, enthalpy wheel shaft 3, ceramic core 6 and gas-powered mechanism, end plate 4 is located at respectively the two ends of urceolus 5, enthalpy wheel shaft 3 runs through the two ends of urceolus 5 along the axis of urceolus, ceramic core 6 is located in urceolus 5 and is set on enthalpy wheel shaft 3; The air outlet position of the air outlet of gas-powered mechanism and air compressor machine and pile is relative, and gas-powered mechanism is fixedly connected with end plate, and gas-powered mechanism also is connected with the end of enthalpy wheel shaft.
Gas-powered mechanism comprises gas hood 8, impeller 1, gear 2 and pipe joint 7, the end of impeller 1, gear 2 and enthalpy wheel shaft 3 is located in gas hood 8, the air inlet of gas hood is over against the air-out of air compressor machine and the moisture delivery outlet of pile, gear 2 comprises driving gear and driven gear, impeller 1 and driving gear rigid attachment, the end key connecting of driven gear and enthalpy wheel shaft 3, impeller is corresponding with the position of gas hood air inlet; Described pipe joint is located on the end plate of the other end corresponding with gas hood.
Be provided with several passages that are parallel to each other with the enthalpy wheel shaft in ceramic core, the cross section of described ceramic core is network structure, and is specifically shown in Figure 3, and ceramic core adopts the ceramic material of porous water-absorbing.
Operation principle of the present invention is: the dry air by air compressor machine output enters the enthalpy wheel along a to the air inlet from gas hood, and drives impeller 1 is rotated, the driving gear of impeller outside is synchronizeed with impeller and is rotated, and rotates thereby drive the driven gear that is engaged with, and drives enthalpy wheel shaft 3 and rotates and drive the enthalpy wheel.Dry air enters ceramic core 6 the first half, carries the moisture of ceramic core 6 inside, become humid air by pipe joint 7 along b to entering pile; The humid air that pile ejects enters the enthalpy wheel along c to the air inlet from gas hood, drives impeller and gear rotate to drive enthalpy wheel operation (this process and above-mentioned consistent) together, at this moment, the first half ceramic core 6 of being taken away moisture by dry air has gone to Lower Half, like this, the moisture of the humid air of coming in from the air inlet of gas hood is just stayed ceramic core 6, the air that is sucked away at last moisture by pipe joint 7 along d to discharge.Reciprocation cycle like this is to reach the humidification effect.That is to say, be that the gas that both sides enter enthalpy wheel drives respectively two impellers with gear makes up rotation, drives same enthalpy wheel shaft 3 and rotate, thereby the enthalpy wheel is moved.
