Catalytic decomposition low-concentration hydrogen peroxide reactor, combustion chamber and application thereof

Abstract

The invention relates to a catalytic decomposition low-concentration hydrogen peroxide reactor and a combustion chamber, which solve the problem that in the prior art, price is expensive, safety is not high, freezing point is high, decomposition temperature and ignition temperature are high, purpose is single and the like. A multilayer low-bed-load and pre-contact fine silver net catalysis bed for catalytic decomposition of 40%-70% of hydrogen peroxide is adopted, and service life is greatly prolonged. Radial holes or/and axial holes are arranged on a laryngeal casing of the catalytic decomposition low-concentration hydrogen peroxide reactor for using in underground reactor oil recovery by heating, mining and marine accident self rescuing and a life support system of spaceships and rocket oxidizer storage tank supercharging. The catalytic decomposition low-concentration hydrogen peroxide combustion chamber is provided with a plurality of radial spraying holes for spraying diesel oil or kerosene, an electronic spark plug for ignition, a combustion chamber body with the 40%-70% of hydrogen peroxide serving as a regeneration cooling agent and two kinds of spraying tubes, and the catalytic decomposition low-concentration hydrogen peroxide combustion chamber can be used for thrust chamber gas spraying thrust of a plurality of military projects and road ice and snow removal by heat and crude oil pollution.

Description

technical field [0001] The invention relates to a reactor for catalytically decomposing hydrogen peroxide and a combustion chamber for catalytically decomposing hydrogen peroxide based on the reactor. Background technique [0002] Catalytic decomposition hydrogen peroxide reactors and combustion chambers have been developed for more than 60 years, and the concentration of hydrogen peroxide has increased from 80% at the beginning to 90%-98% now. 90%-98% hydrogen peroxide, which is expensive and not safe enough, has a freezing point of -11.5°C-2.5°C, a catalytic decomposition temperature of 740°C-946°C, and a combustion temperature of 2450°C-2660°C when injected into kerosene. It is only used in aerospace The rocket motor drives the turbopump and thrust chamber jet propulsion. [0003] The existing thermal oil recovery technology is mainly water steam injection, which is effective and can be applied industrially. However, it is necessary to build a boiler steam station and a ...
