The application discloses a multi-section security MCC common single diesel generator set emergency power supply switching method, and belongs to the field of thermal power generation, which comprises the following steps: when the working and standby power supply of any section of security MCC are all lost, the CTTS sends a start instruction to the diesel generator set; after the diesel generator set is started, the section of security MCC is switched to diesel supply; the rest of the lost sections are switched in a preset order until all the lost sections are switched to diesel supply; when the working power supply of any section of security MCC is restored, the ATS switches to the power supply and sends a synchronization instruction; after the diesel generator set is synchronized, the section of CTTS control is parallel to the plant power for a short time, then the plant power is switched back, the connection with the diesel generator set is disconnected and an exit signal is sent; after receiving the signal, the diesel generator set delays and disconnects the corresponding contact breaker; the above-mentioned restoration steps are repeated until all the security MCCs restore the plant power supply, and finally the diesel generator set is disconnected from the total outlet breaker and is stopped. Through grouping restoration and synchronization switching, the application realizes the orderly access of the security MCC to the diesel generator after the power supply is lost, and the smooth switching back to the plant power when the power supply is restored, thereby ensuring the continuous and reliable power supply.

This application relates to a reverse osmosis acid addition device and its regulation and control method, belonging to the field of reverse osmosis water treatment technology. To solve the problem of unreasonable acid addition points in the acid addition device, it includes a corrosion-resistant storage tank, a metering pump, a pulsation damper, a back pressure valve, a multi-stage static mixer, a security filter, an online water quality monitoring unit, and an intelligent control unit. The inlet of the metering pump is connected to the corrosion-resistant storage tank, and the outlet of the metering pump is connected sequentially to the pulsation damper and the back pressure valve, and then connected to the inlet pipe at the front end of the security filter, forming the acid addition point. This application ensures that the acid and the inlet water reach a fully uniform mixing state before entering the security filter, eliminating the defects of local over-acid corrosion of pipes and membrane elements caused by unreasonable acid addition points and insufficient mixing, as well as the defects of local high alkalinity still causing calcium carbonate scaling, thus ensuring the long-term stable operation of the reverse osmosis system and extending the service life of the membrane elements.

The utility model discloses a spare power automatic switching and motor protection quick switching device for security section relates to security section equipment technical field. The utility model discloses utilize open contact and closed contact to realize motor controller control power supply and self -starting function detection voltage quick switching between work and standby power supply, guarantee the switch in the spare power automatic switching process and keep in the operating state, the power failure of each equipment in the section is shortened to 1 within the hour from 6 seconds to restore time. Guarantee unit safe and reliable operation, through open contact and closed contact respectively introduce this section bus voltage signal and spare section voltage signal to motor protection voltage terminal, utilize the opening and closing contact synchronous action when switching contactor action, realized this section bus voltage and spare section voltage effective isolation, prevent two section voltage loop event from happening, through the open contact of switching contactor string connection work power insurance and work position contact point, cooperate with the closed contact of spare control power that introduces, prevent two control power loop.

The application belongs to the technical field of filter elements, and discloses a high-flux folded security filter element, which comprises a folded filter element, a sealing plate, a mounting ring and an inlet pipe. A plurality of first inner plates are circumferentially and spacedly arranged near the central opening of the mounting ring, and a plurality of first outer plates are circumferentially and spacedly arranged away from the central opening. A plurality of second inner plates are circumferentially and spacedly arranged near the center of the sealing plate, and a plurality of second outer plates are circumferentially and spacedly arranged away from the center. The two sides of the first inner plate are respectively axially and slidably connected with the adjacent second inner plate, and the two sides of the first outer plate are respectively axially and slidably connected with the adjacent second outer plate. The axial sliding connection of the first inner plate with the second inner plate and the axial sliding connection of the first outer plate with the second outer plate realize dynamic adjustment of the filtering area of the filter element. When the flow rate is low, the sealing plate is close to the mounting ring, the folded filter element has dense wrinkles, and the filtering effect is good. When the flow rate is high, the fluid pressure drives the sealing plate and the mounting ring to be axially separated, the wrinkles are unfolded to expand the channel and reduce the pressure, and the filtering efficiency is ensured.
