An ECU of a control apparatus further alleviates a fluctuation in a power generation amount of a fuel cell stack with respect to the power required by an inverter apparatus, when a power supply circuit configured by each of contactors and a power supply inlet 11a supplies the power to the inverter apparatus compared with when a vehicle is driving. The ECU, when the power supply circuit supplies power to the inverter apparatus, stops the power generation of the fuel cell stack in a case where a remaining capacity in a battery is greater than or equal to a predetermined remaining capacity, and inhibits the fuel cell stack from stopping the power generation in a case where the power supplied to the inverter apparatus by the power supply circuit is greater than or equal to a predetermined power supply amount.

The invention relates to an out-of-season cultivation method of fresh gingers. The method comprises the steps that A, a film tunnel is set up, wherein atomization and spray irrigation equipment is installed inside the tunnel and an atomizer is installed at the top inside the tunnel; B, the middle and the two sides inside the tunnel in the longitudinal direction are respectively provided with a water collecting ditch, and net pipes are embedded in the lower portions of the water collecting ditches, wherein the net pipes are used for collecting and temporarily storing warm water leaking from the water collecting ditches, and enabling the warm water to well permeate towards the sand layers and the underground, and meanwhile heat energy is transmitted to the soil layers and the underground along with the permeation of the warm water; C, ridging cultivation is carried out, wherein high and low ridges are adopted for planting, low-density shallow layers are adopted for planting on the low ridges, and high-density deep layers are adopted for planting on the high ridges; D, planting and harvesting are carried out, wherein the fresh gingers start to be planted when seed gingers are harvested on other places in November of Gregorian calendar, the planted fresh gingers on the high ridges can be harvested and dug before and after the Spring Festival, young gingers and old gingers appear on the market at the same time, and the planted fresh gingers on the main planting rows of the low ridges can be harvested and dug successively after the Tomb-sweeping Day of the next year to October of Gregorian calendar. According to the method, the time when the fresh gingers appear on the market is the best-selling period (in summer and autumn), the fresh gingers can directly appear on the market after being harvested, storage equipment and storage troubles are reduced, and natural risk and market risk are avoided completely.

The invention discloses a filtering device. One end of the filtering device is an air inlet end and the other end of the filtering device is a connection end; the air inlet end is provided with an annular filtering cavity into which an air inlet pipe of a vacuum adjusting device is inserted; the connection end is combined with a shell of the vacuum adjusting device; the filtering cavity is internally provided with annular filtering sponge which is coaxial with the air inlet pipe; an air vent is arranged on the wall face, which is located below the filtering sponge, of the filtering cavity; a buffering cavity communicated with the air vent is arranged at the outer side of the filtering cavity; one side, which is far away from the connection end, of the buffering cavity is provided with an air inlet communicated with external atmosphere; and the connection end is provided with a bent part which enables air to flow in an opposite direction to reach the air vent. The invention further discloses the vacuum adjusting device. The filtering device disclosed by the invention is applicable to various vacuum adjusting devices and can ensure smooth air feeding of the vacuum adjusting devices for a long time so as to avoid blocking and reduce the times of maintenance.

The invention discloses an automatic control method for large valve switching of an ethylene cracking furnace, including: initialization and initial permissible work inspection, switching the cracking furnace mode from a hot standby mode to a large valve automatic switching mode, and starting the pressure difference stable state judgment logic , start the closing action of the pyrolysis gas valve until the pressure difference PDZI of the large valve reaches the first set value, stop closing the cracking gas large valve; after the pressure difference of the PDZI large valve reaches the first set value, start to open the coke cleaning gas large valve Action: After opening the coke cleaning gas valve to a certain valve position, start the judgment logic of pressure difference stability state, continue to open the coke cleaning gas valve after the pressure difference is stable, until the PDZI pressure difference is less than the second set value, stop opening the coke cleaning gas valve valve; repeat the operation until the cracking gas valve is completely closed / coke-cleaning gas valve is fully opened. The method has fast adaptive control response and reduces manual operations, which is conducive to improving the stability of the cracking furnace mode switching process and the control accuracy of pressure difference, and reduces the safety risk of the device.

The invention relates to a cantilever type overflow weir, which comprises a weir plate, a cantilever, a tray overflow port and a weir plate opening. The weir plate is connected with the cantilever and stretches into a downspout; and the tray overflow port is formed between the weir plate and a tray outlet. The structure can eliminate resonance formed by fluid and a tower device at a low air speed, damage the fluctuation of a liquid layer on the plate, expand lower limit for operation and increase the elastic range by 5 to15 percent; when a liquid level is small, liquid flow directly enters the downspout from the tray overflow port without throwing beyond the weir so as not to form an air cavity in the downspout; when the liquid level is large, liquid overflows from the tray overflow port and the weir plate to reduce the height of liquid head on the weir by splitting the liquid; thus the liquid flow on the plate more tends to be plug flow to relieve retention and back-mixing; two streams of liquid flow interact in the downspout to help the gas liberation; the weir plate opening on the weir plate can discharge part of the liquid. The cantilever type overflow weir has a simple structure, can improve the operational stability of the tray and the downspout and is applicable to various liquid levels.

Two rotary mechanism parts (70, 80) are provided in a rotary expander (60). The first rotary mechanism part (70) is smaller in displacement volume than the second rotary mechanism part (80). A first low-pressure chamber (74) of the first rotary mechanism part (70) and a second high-pressure chamber (83) of the second rotary mechanism part (80) are fluidly connected together by a communicating passageway (64), thereby forming a single expansion chamber (66). High-pressure refrigerant introduced into the first rotary mechanism part (70) expands in the expansion chamber (66). An injection passageway (37) is fluidly connected to the communicating passageway (64). When an motor-operated valve (90) is placed in the open state, high-pressure refrigerant is introduced into the expansion chamber (66) also from the injection passageway (37). This makes it possible to inhibit the drop in power recovery efficiency, even in the condition that causes the actual expansion ratio to fall below the design expansion ratio.
