The application relates to a multifunctional support for assembled decoration outer wall, which is used for being installed on the outer facade of a building and comprises a first support, a first photovoltaic panel, a second support and a second photovoltaic panel, the first support is used for being connected to the outer facade, the first photovoltaic panel is arranged on the first support and can be arranged opposite to a window on the outer facade, the light transmittance of the first photovoltaic panel is greater than or equal to 40%, the second support is used for being connected to the outer facade and is located below the first support, the second support has a containing space, and the second photovoltaic panel is arranged on the side of the second support away from the outer facade. The first photovoltaic panel is installed on the first support, the second photovoltaic panel is installed on the second support, the first photovoltaic panel and the second photovoltaic panel synchronously generate electricity, the laying area of the outer facade of the building is further increased, and the solar energy collection potential of the outer facade of the building is exerted.

The disclosed venting liquefied natural gas recovery system and recovery method, comprising a condensation recovery heat exchanger, a feed inlet of the condensation recovery heat exchanger being communicated with a venting pipeline, and a pretreatment assembly for filtering the natural gas to be recovered being further arranged between the venting pipeline and the condensation recovery heat exchanger; the condensation recovery heat exchanger being communicated with a liquid nitrogen storage device through a liquid nitrogen feed pipe, and the condensation recovery heat exchanger being provided with a heat exchange coil and a nitrogen gas discharge pipe, two ends of the heat exchange coil being respectively extended to outside of the condensation recovery heat exchanger and communicated with the pretreatment assembly and a gas-liquid separation device, and the gas-liquid separation device being communicated with a natural gas storage device through a pipeline at a liquid outlet. The present application solves the problem of resource waste caused by direct combustion and discharge of the natural gas remaining in the process section in the prior art.

The present invention relates to a water-saving and energy-saving hydrogen production system and method. A hydrogen separator and a hydrogen scrubber are sequentially connected to the hydrogen outlet of an electrolytic cell, and are respectively used for gas-liquid separation and cooling purification of hydrogen; the low-temperature passage of a hydrogen heat exchanger is connected to the hydrogen outlet of the hydrogen scrubber and the hydrogen inlet of a deoxygenation tower, and the high-temperature passage of the hydrogen heat exchanger is connected to the hydrogen outlet of the deoxygenation tower and the hydrogen inlet of a hydrogen cooler; the deoxygenation tower conducts a catalytic reaction on the oxygen mixed in hydrogen to generate water; the hydrogen cooler cools the deoxygenated hydrogen after heat exchange and realizes moisture condensation; a gas-water separator is connected to the hydrogen outlet of the hydrogen cooler to remove the liquid water in hydrogen; a drying tower is connected to the hydrogen outlet of the gas-water separator for drying hydrogen; an electrolyte heat exchange module is used for the electrolyte flowing out of the hydrogen separator to exchange heat with an external system and then flow back into the electrolytic cell. The present invention significantly reduces the energy consumption and water consumption of the hydrogen production system, improves the energy utilization rate and the adaptability in water-scarce areas, and improves the economy of green hydrogen.
