Description
Technical field
The present invention relates to solid-state storage hydrogen and gaseous state hydrogen storage technology, belong to storage, transportation and the supply field of hydrogen.
Background technology
Hydrogen Energy is a kind of generally acknowledged cleaning secondary energy, and its research, development and utilization just are being subject to paying attention to more and more widely.Because the hydrogen quality is little, be gaseous state under normal temperature, inflammable and explosive, have again dispersed when acting as a fuel and be interrupted the characteristics of using, so hydrogen storage is a key issue utilizing on a large scale Hydrogen Energy.At present the high-pressure gaseous hydrogen storage technology is ripe, and the weight hydrogen-storage density is high, and commercial applications is extensive, yet it is faced with problems such as taking up an area large, potential safety hazard, is not suitable for Mobile fuel battery, portable testing set etc. and uses the hydrogen field.
Solid-state hydrogen storage technology relatively high pressure gaseous state storage hydrogen improved to a great extent the volume hydrogen-storage density, but the weight hydrogen-storage density is still relatively low, apart from the large-scale commercial applications application, very large distance is arranged.And also have in actual applications obvious defective based on the storage hydrogen device of solid-state hydrogen storage technology: on the one hand, hydrogen storage alloy can be emitted amount of heat when inhaling hydrogen, makes storage hydrogen actuator temperature raise gradually, causes inhaling hydrogen and slows down even and can't inhale hydrogen; On the other hand, hydrogen storage alloy need to absorb amount of heat when putting hydrogen, makes storage hydrogen actuator temperature reduce gradually, and then puts the hydrogen process and be restricted.Therefore store up the hydrogen device the extraneous good heat exchange condition that provides is provided when work, such as supporting water-bath circulation or wind circulation, increased cost on the one hand, also increased on the other hand energy expenditure, reduced energy efficiency.
Many emphasized in design of patent optimized heat radiation structure in the past improves the thermal conductivity of hydrogen-storing device inside, and then the heat exchange in enhancing and the external world; Perhaps by the heat that produces in storage hydrogen device working process is used, the raising energy utilization efficiency of certain limit.But all do not relate in hydrogen-storing device inside and realize heat exchange, thereby effectively reduce energy consumption.
Summary of the invention
For the existing problem of above-mentioned prior art, the invention provides a kind of composite hydrogen occluding system, in conjunction with solid-state hydrogen storage technology and high-pressure gaseous hydrogen storage technology, relatively solid-state storage hydrogen, this system has improved the weight hydrogen-storage density greatly, its volume hydrogen-storage density relatively high pressure gaseous state storage hydrogen also tool has great advantage, and satisfies actual operation requirements; This system has realized the heat exchange that device is inner simultaneously, have temperature controlled, charge and discharge the characteristics such as hydrogen speed is fast.。
The technical solution adopted in the present invention is:
A kind of composite hydrogen occluding system is provided, comprises one-level hydrogen container, secondary hydrogen container, scatterer, temperature sensor.Add heat radiator in the one-level hydrogen container, fill hydrogen storing alloy powder in heat spreader structures, temperature sensor is inserted into hydrogen storing alloy powder inside, Real-Time Monitoring temperature; The secondary hydrogen container is a slack tank body, is connected with valve with pipeline between two hydrogen containers, controls the convection current of hydrogen by valve.In order to guarantee that hydrogen storing alloy powder is deposited in heat spreader structures, scatterer two ends add barrier sheet; In order to guarantee that hydrogen storing alloy powder does not flow out from the exit, two import and exports of one-level hydrogen container all add filter.
Described scatterer and hydrogen container close contact, scatterer is inner improves the contact area of hydrogen storing alloy powder and hydrogen for bending the font path or adding metal fin to form sector structure, effectively improves the thermal conductivity between hydrogen storing alloy powder.
Described barrier sheet has certain pliability, can adapt to the distortion due to scatterer after hydrogen storing alloy powder suction hydrogen-expansion.
The hole of described filter is not more than 20 microns, prevents that hydrogen storing alloy powder from seeing through.
Control the connection of two hydrogen containers with valve, detect in real time the temperature of hydrogen storing alloy powder with temperature sensor.This composite hydrogen occluding system can realize good thermo-efficiency:
(1) fill the hydrogen process: heat release when hydrogen storage alloy is inhaled hydrogen, system temperature is raise gradually, when temperature during higher than set(ting)value, Open valve is also regulated, make the amount of hydrogen inflow secondary hydrogen container in the one-level hydrogen container higher than the amounts of hydrogen that enters system, this moment, hydrogen storing alloy powder partly began to put hydrogen, and then absorbed heat, and system temperature is reduced.
(2) put the hydrogen process: absorb heat when hydrogen storage alloy is put hydrogen, system temperature is reduced gradually, hydrogen discharging speed slows down.When temperature during lower than set(ting)value, Open valve makes the amount of hydrogen that hydrogen in the secondary hydrogen container enters the one-level hydrogen container higher than the hydrogen desorption capacity of system, and this moment, hydrogen storing alloy powder partly began to inhale hydrogen, and then heat release, and system temperature is raise.
The volume of (3) two hydrogen containers can be adjusted, and can anti-certain high pressure, and when volume increases or the pressure of hydrogen supply when improving, the storable amounts of hydrogen of secondary hydrogen container can increase, so can better regulate the one-level hydrogen container suction hydrogen, put the hydrogen process.
