Embodiment Construction

[0014] Below in conjunction with accompanying drawing description and specific implementation, the present invention will be further described:

[0015] As shown in the figure, the test workshop of this system consists of five discharge points and the discharge point on the top of the liquid hydrogen storage tank. The hydrogen discharge in the test workshop includes discharge from the engine pre-cooling outlet, engine hydrogen tank pressurized discharge, engine servo energy discharge, and hydrogen discharge. Deflate before the pump, and discharge the hydrogen filling pipeline on the ground.

[0016] During the test, the five hydrogen exhaust pipelines in the test workshop were successively collected into the discharge main pipe of the test workshop according to the high and low pressure and different flow rates. This pipe then extended vertically upward for 14m along the tower, and then connected to the 18m liquid hydrogen platform. , respectively connected to the discharge ma...

Abstract

The invention provides a safe discharging system for hydrogen centralized management. The safe discharging system is composed of a pneumatic valve 1, a temperature and pressure measuring point 2, a manual stop valve 3, a solenoid valve 4 and corresponding pipelines. According to the safe discharging system, a principle of safe discharging of centralized management is adopted for the first time, a high-altitude discharging method is applied to a large-flow multi-point hydrogen discharging system, and the safe discharging system is used for safe discharging of low-temperature hydrogen which is required to be treated and generated from a test workshope and a hydrogen room during the stages of engine test preparation, an engine test and engine test ending.

Description

technical field [0001] The invention is a hydrogen centralized management safety discharge system, which is used for the centralized safe discharge of hydrogen in a certain type of hydrogen-oxygen engine test, and can also be applied to the safe discharge of hydrogen in other and future new models of hydrogen-oxygen rocket engines or power system tests. Background technique [0002] In the tank and pipeline precooling stage, engine precooling stage, test stage, test end stage or emergency shutdown stage in the hydrogen-oxygen engine test, it is necessary to deal with low-temperature hydrogen at different flow rates and temperatures between the test room and liquid hydrogen. The most critical issue in the hydrogen discharge process is to ensure its safe discharge. This system solves this problem well by adopting the method of high-altitude concentrated discharge. Contents of the invention [0003] The technology of the present invention solves the problem: the present inven...
