Description

Technical Field

[0002] When the temperature and pressure of the reaction pool of the existing nitrogen generator are reduced, the pipeline connected to the reaction pool will return liquid, affecting the purity of the nitrogen. In order to solve the above problem, people have invented some methods, for example, patent publication number CN218025452U, which discloses a nitrogen generator non-return liquid device in the field of generator technology, including a reaction pool, the top of the reaction pool is connected to an air supply pipe and a hydrogen pipe, a motor is installed on the side of the reaction pool, and the output end of the motor is connected to an air baffle, and the width of the air baffle is equal to the width of the reaction pool. The inner wall of the reaction tank is fixedly connected with an anti-backflow plate, the top of the anti-backflow plate is provided with a leakage hole, the bottom of the reaction tank is connected with a drain pipe, the surface of the drain pipe is penetrated with a water pump, and the top of the reaction tank is connected with a pure water delivery pipe. The utility model increases the air pressure in the reaction tank by introducing pure water into the reaction tank to prevent liquid from returning to the drain pipe. The water pump can continuously discharge the water in the reaction tank to avoid reflux of liquid in the reaction tank. The device adjusts the air pressure in the reaction tank by arranging a pure water replenishing component to avoid liquid returning during the hydrogen-oxygen reaction.

[0003] However, in actual use, the air baffle in the above patent does not adopt any sealing means, and the sealing between the air baffle and the reaction pool cannot be guaranteed. Even if sealing means are adopted on the air baffle, the air baffle needs to be replaced due to the frequent squeezing and friction between the air baffle and the reaction pool, which is inconvenient to use.
