The invention relates to the field of maternal and infant products, in particular to a baby feeder. An airbag type baby feeder, comprising a pneumatic chamber, a propelling airbag and a food bag, an air inlet and an air outlet are arranged on the air pressure chamber, an air inlet check valve is arranged in the air inlet, and an air inlet is arranged in the air outlet There is an air outlet one-way valve, and the air outlet communicates with the opening of the propelling air bag; the food bag is set outside the propelling air bag, and the end of the food bag is provided with a feeding outlet, and the storage space of the food bag can be changed by the shrinking and expanding of the propelling air bag; the air pressure The junction of the chamber, the propulsion air bag and the food bag is sealed and fastened by the casing. The invention utilizes the air pressure chamber to control the expansion and contraction of the propelling air bag, realizes food boosting, and assists the baby to eat; the air pressure chamber allows the baby to grasp and pinch independently, and can also exercise the baby's grasping ability at the same time, and uses the whistle to lure the baby to grasp and pinch The invention not only guarantees the autonomy of the baby in exercising the grasping ability, but also makes the feeder easier to extrude food, which has wide popularization and application value.

The proposed double-loop nuclear reactor steam generating plant having a blowdown and drainage system is implemented on the basis of a closed loop without the conventional blowdown tanks and is designed for maximum pressure of the working fluid in the steam generators. Steam generator blowdown water is brought together into a single line, cooled in a regenerative heat exchanger then in a blowdownand drainage aftercooler, and removed from the containment building. Outside the containment building, the steam generator blowdown water is fed for treatment into a system for the specialized treatment of steam generator blowdown water, designed for maximum pressure of the working fluid in the steam generators. After treatment, the blowdown water is returned to the containment building and, via the regenerative heat exchanger, to feed pipes of each steam generator. The technical result is an increase in steam generator blowdown flow, which leads to the accelerated normalization of the water chemistry conditions even in the event of significant deviations and, as a result, to an increase in the working life of each steam generator and of the steam generating plant as a whole, and also leads to a reduction in energy losses during the return of the treated blowdown water to the second loop, while at the same time rendering the system autonomous due to the absence of a link to turbine hall equipment.
