Problems solved by technology

However, the device has no control over the humidity of the gas, nor does it take measures against possible icing in the lines
[0010] Through analysis, the above three patents did not control the humidity of the low-temperature gas, and did not deal with the possible freezing phenomenon in the pipeline

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0038] A large flow low temperature gas temperature and humidity control equipment, such as figure 1 shown, including:

[0039] The gas source 1 is used to provide high-pressure gas. The gas source 1 can be compressed gas in a can, or high-pressure gas from a compressor. ;

[0040] A decompression device, the input end of which is connected to the gas source 1, is used to adjust the pressure and flow rate of the high-pressure gas provided by the gas source 1;

[0041] Also includes:

[0042] The liquid thermostat 7 is provided with a first heat exchanger 8 and a second heat exchan...

Abstract

The invention relates to a high-flow-rate low-temperature gas temperature-humidity control device. The high-flow-rate low-temperature gas temperature-humidity control device comprises a gas source, adecompression apparatus, a liquid thermostat, a first dehumidifying apparatus and a second dehumidifying apparatus, wherein the gas source is used for providing high-pressure gas; an input end of thedecompression apparatus is connected with the gas source and used for adjusting the gas pressure and the flow rate of the high-pressure gas; a first heat exchanger and a second heat exchanger are arranged inside the liquid thermostat; the first dehumidifying apparatus comprises a first dewatering assembly and a first pipeline heater; and the second dehumidifying apparatus comprises a second dewatering assembly and a second pipeline heater. Compared with the prior art, two heat exchangers are provided, the corresponding dewatering assembly and pipeline heater are arranged behind each heat exchanger, and the pipeline heater is arranged behind the dewatering apparatus, so that the water content in the gas can be greatly reduced, the possible icing amount is reduced, and a fuel cell is prevented from being damaged.

Description

technical field [0001] The invention relates to a fuel cell technology, in particular to a large-flow low-temperature gas temperature and humidity control device. Background technique [0002] The low-temperature cold start of the fuel cell stack refers to the cold start of the fuel cell stack in an environment below 0°C. At this time, the temperature of hydrogen and air entering the stack is very low, even at ambient temperature. To simulate the low-temperature cold start of the stack, it is necessary to supply the low-temperature gas with adjustable temperature and humidity to the stack. [0003] Low-temperature air is required for performance testing of gasoline engines and diesel engines in low-temperature environments. [0004] When the room temperature gas is cooled below 0°C, the water vapor contained in the gas will condense into liquid water after reaching the saturated vapor pressure, and even freeze at below 0°C. [0005] At present, the preparation of low-temp...
