Description
Technical field
The utility model belongs to fuel cell field, and in particular to a kind of temperature for quickly adjusting pipeline gas, humidity
Device.
Background technique
Some industrial process are needed to gas, such as the pipeline gas with certain pressure is heated up, is humidified.Especially
For proton exchanging film fuel battery test platform supply gas humidification, need the gas flow according to pile difference operating condition,
Pressure, temperature carry out quick temperature humidity adjusting.
Test to fuel cell pile needs to control the temperature, pressure, humidity, flow of gas supply, to detect pile
Various performances, find out optimal conditions.Wherein to the humidification of air mainly using bubbling, spraying spray, film exchange, steam etc.
Mode is realized.But technology still has some deficits in terms of quick response temperature, pressure, humidity, flow change simultaneously at present, need
Meet technology growth requirement in more progress.On the humidifying device of concrete specification, for the flow lower bound in its range,
Especially high-temperature, high humility when, routine techniques due to the container of test device, pipe fitting, valve, detector etc. heat dissipation and hold
The variation into heap gaseous state is easily led to, is mainly shown as that the situations such as water droplet occur in the decline of temperature humidity, condensation.
Its volume of bubble type humidifying device is bigger, and own temperature then needs high-power power branch if necessary to quickly adjusting
It holds, has using the method for peripheral high temperature two kinds of fluid providers of low temperature and increase temperature adjustment speed, but it is actually total
Volume and power are huger.Generally it is only applicable to low-power equipment.
As patent CN101076910A may be implemented accurately to control the temperature and humidity after humidification by bubbling, temperature adjustment.
But the volume of this bubbling device itself is a feature greatly, even if pressure does not change, temperature change is changed, such as from
Maximum temperature is reduced to minimum temperature, needs the peripheral Cooling and Heat Source of bigger one to exchange as heat and supports, equipment itself is not
It is adapted to quick temperature and humidity adjustment mode.
For example, patent CN101829511A uses two-way gas control mode, it is humidified, is not humidified all the way all the way, by making
Flow is controlled with two sets of flow control systems, but there is no carry out quickly adjusting control to temperature.
Fountain improves the gas-liquid contact effect of humidification, and generally using heat exchanger to air preheat, then spray is humidified,
Finally exchange heat again to the mixed gas of gas and water mist.
For example, patent CN206115313U using preheating, is shunted, part is humidified, it is wet can to accelerate temperature for mixing, temperature control
The variation of degree controls.It, which is heated, relies on recirculated water, needs the heat exchanger of large area, the volume and weight of the heat exchanger of large area is very
Greatly, determine that device system thermal capacitance itself is big, the feature that the power that temperature adjustment needs is big, temperature change is slow.
In addition, the drawbacks of current overwhelming majority humidity sensor all measures failure in the presence of probe if being stained with condensed water,
Especially small flow when, from low temperature to high-temperature high-humidity change, it is easier to occur condensed water on probe.In quick control manipulation
In, if using hygrometry result as control condition, this humidity data will affect the accuracy of control adjustment and anti-
Speed is presented, is unfavorable for quickly adjusting.
In the test macro of fuel cell exploitation at present, generally existing equipment volume is huge, and temperature and humidity changes low-response, control
The problems such as low precision processed, these problems are urgently to be resolved.
Utility model content
