Problems solved by technology

However, since the amount of molecular sieve used in the low-temperature molecular sieve adsorption pump is approximately proportional to the total gas flow, the presence of nitrogen dilution gas is not conducive to reducing the volume and weight of the low-temperature molecular sieve adsorption pump.

Abstract

The invention discloses an oxiodide chemical laser based on pure chlorine gas as reacting gas, which is characterized by the following: butting sprayer component on the outlet of single heavy oxygen generator; setting the hypersonic oxiodide composite sprayer in the sprayer component as array pattern; setting the caliber of iodine injector at phi 0.5mm and the distance of two rows of iodine injector at 2mm; making the even distance between injector and sprayer throat at 3-5mm; designing the Mach number of sprayer at 2.2-2.8 and each unit throat breadth of sprayer multiplied by 2 at 4-6 mm; setting the breadth of outlet multiplied by 3 at 10-15mm and gas-liquid reacting specific surface area of single heavy oxygen generator at 4-6cm-1; making the length of even gas-liquid reacting area multiplied by 4 at 8-12cm along flow direction and chlorine gas flux of unit cross-section at 2.8mmol / s.cm2.

Description

technical field [0001] The invention relates to an oxygen-iodine chemical laser, in particular to a diluent-free oxygen-iodine chemical laser which uses pure chlorine gas as a reaction gas and does not need any diluent gas. Background technique [0002] The traditional oxygen iodine chemical laser (COIL for short) uses a large amount of helium as the diluent gas. On the one hand, helium resources are scarce, expensive, and costly to use, which is not conducive to the industrial application of COIL; COIL can no longer adapt to the application of this new technology, because the zeolite molecular sieve used in the low temperature molecular sieve adsorption pump can only effectively adsorb oxygen (the gas produced by COIL itself) and nitrogen at low temperature. [0003] In recent years, COIL using nitrogen as a diluent has appeared, and the above problems can be solved. However, since the amount of molecular sieve used in the low-temperature molecular sieve adsorption pump i...
