Peroxide supplying system and safety operation method

Abstract

The invention relates to a peroxide supplying system which comprises an operation console and a pipeline system, wherein the operation console is provided with one path of a nitrogen source, and is used for simultaneously realizing pipeline blowdown, pneumatic valve operating gas supply and storage box pressurization. All pipeline systems in direct contact with peroxide are made of stainless steel, and all valves adopt stainless steel hand stop valves and pneumatic valves, wherein blowing gas and pneumatic valve operating gas share one pipeline, and storage box pressurization gas independently adopts one pipeline; the outlet of the storage box pressurization gas is provided with a one way valve and a safety valve. The pipeline system of the peroxide supplying system is provided with a distilled water inlet, one end of which can be led to the peroxide storage box and the other end of which can be led to the pipeline system. The pipeline system of the peroxide supplying system is provided with two paths of nitrogen blowdown, wherein one path is designed in the position of a storage box outlet and is controlled by the hand stop valves; the other path is designed in the pipeline outlet of the supplying system and is controlled by the pneumatic valves. The peroxide supplying system is operated by three steps: step one, injecting the peroxide; step two, pressurizing the storage box; step three, clean and blow distilled water in the pipeline system after the test is finished. The peroxide can be injected with a suction type scheme, gas in the storage box is pumped to reduce pressure in the storage box so that the peroxide is sucked into the storage box. When a vacuum pump is used for pumping the gas in the storage box, the gas enters the vacuum pump after passing through a water box.

Description

【Technical field】 [0001] The invention relates to a hydrogen peroxide supply system and a safe operation method, and is particularly suitable for a test system for rocket engine ground tests using high-concentration hydrogen peroxide as propellant. 【Background technique】 [0002] N currently used in aerospace engine systems 2 o 4 Although hydrazine (unsymmetrical dimethylhydrazine, monomethylhydrazine, hydrazine, etc.) fuels have good specific impulse performance and spontaneous combustion characteristics, their toxicity is high, causing serious harm to human health and the environment. At the same time, Their production, storage, transportation, use and treatment are complex processes, and the cost of use is relatively high. Hydrogen peroxide has the characteristics of high density, non-toxicity, and low saturated vapor pressure, and has attracted people's attention. Although breakthroughs have been made in the research of hydrogen peroxide-based non-toxic spontaneous co...
