Abstract: A power converter box and at least one junction box are integrated on a backplane of the photovoltaic module as a whole, and there is a cable for connecting the power converter and the junction box. In this case, relative to the conventional technology in which a junction box is independent of a power converter, a length of a cable used when the junction box and the power converter box are taken as a whole is shorter than a length of a cable used in the conventional technology. In this case, compared with the conventional technology in which a cable is connected to an independently placed power converter, the power converter only needs to establish a connection relationship by using a solder ribbon, a circuit board cable, and the like with low costs, so that production costs are low.

Abstract: Disclosed are a fluidized bed separation method and device for methanol-to-olefins quenched water. The method may subject quenched water to liquid-solid separation via a micro-cyclone separator. The method may also subject clear liquid from the micro-cyclone separator to a secondary separation via a fluidized bed separator, then sending the same to an olefin separation device, then recovering some waste heat of the quenched water, and then returning the same to a quenching tower after performing heat exchange. The method may also regenerate a separation medium by reversely feeding stripping tower purified water or quenched water, so as to release catalyst particles absorbed by the separation medium. The method may also send a catalyst slurry concentrated by the micro-cyclone separator and the fluidized bed separator to a filter-press unit for filter-press dehydration, so as to recover a catalyst.
