Description
Technical field
Patent of the present invention belongs to damping device, relates to a kind of industrial gas humidification device.
Background technology
, oil price surging epoch nervous in current global energy, the searching new forms of energy are the task of top priority as the substitute of fossil fuel.Because Hydrogen Energy is with the obvious advantage, therefore cleaning, efficient obtains the support energetically of national governments, adds that various energy source and power enterprise is very confident to the development of fuel cell, so will there be the huge rising space fuel cell future market.
Fuel cell (FuelCell) is the TRT that a kind of chemical energy that will be present in fuel and the oxidant is converted into electric energy.Fuel and air are sent fuel cell respectively to, and electricity is just produced rumly.It exteriorly has both positive and negative polarity and electrolyte etc., and as a storage battery, but it can not " accumulate " but one " power plant " in fact.
PEM is the vitals of fuel cell, and during fuel cell operation, PEM must have the existence of water, otherwise then influences performance, so gas needs humidification.
Traditional bubble type humidifier, gas humidification is unstable, and can not be with the abundant humidification of gas.Patent of the present invention provides a kind of use powder metallurgy to make the abundant humidification of gas, and can let gas humidification stable, and can regulate the humidification of humidity automatically.
Summary of the invention
In order to solve traditional bubble type humidifier, gas humidification is unstable, can not be with the deficiency of the abundant humidification of gas, and patent of the present invention provides a kind of use powder metallurgy, makes the abundant humidification of gas, and can make gas humidification stable, and can regulate the humidifier of humidity automatically.
The technical solution of patent of the present invention is: a kind of industrial gas humidification device, in the humidifier inner chamber, powder metallurgy filter and its inwall removably connect, and inner chamber is divided into top and the bottom.During work, before not ventilating, storage tank is added the water that ormal weight is, restart water pump storage tank water is extracted in the humidifier; Sense liquid level until the water level meter, water pump stops to supply water, action of gravity simultaneously; The closed check valve supply channel guarantees that water is when crossing the gas of certain pressure in the humidifier, and the water that can not take place in the humidifier refluxes; Water level normally is higher than powder metallurgy filter certain distance in the humidifier, causes the powder metallurgy filter under water, belongs to abundant saturation condition.Air inlet pipe is guided under the interior powder plate of inner chamber, and keeps certain distance with it, the existence that the intrinsic powder metallurgy in inner chamber upper and lower part filters; The upper and lower part forms weak resistance; Can prolong the saturated time in water of gas, the slight void of powder metallurgy filter can make gas form countless minute bubbles simultaneously; The contact area of increase saturated gas molecule and top water in the lower part obtains the secondary humidification.This solved traditional bubbling humidifier humidification unstable with the abundant deficiency of humidification.
Humidity is control automatically in good time; The humidity size depends on the contact area of gas molecule in water saturation degree and gas molecule and water, so drive the upper and lower motion of humidifier inner chamber, adjustments of gas and water saturation with stepping motor; With the pre-set upper and lower limit of humidity; Detect the humidity value real-time Transmission through humidity sensor and give single-chip microcomputer, single-chip microcomputer sends instruction, makes stepping motor adjust humidifier inner chamber upper and lower position in real time.When humidity was higher than higher limit, stepping motor drove the humidifier inner chamber and moves upward, otherwise stepping motor drives it and moves downward, and realized regulating automatically humidity.
The beneficial effect of patent of the present invention is: make gas humidification stable, and the abundant humidification of gas, and can regulate humidity automatically, and less demanding to environmental factor.
