Dry-type film oxygen enriching device

Abstract

The invention relates to a dry-type film oxygen enriching device which mainly comprises a control system, an air filtering device, a high-pressure centrifugal fan and an oxygen enriching box, whereinan air inlet of the high-pressure centrifugal fan is connected with the air filtering device; an inner cavity of the oxygen enriching box is provided with an oxygen enriching film assembly and an oxygen enriching air outlet pipeline; the bottom of the oxygen enriching box is provided with an air bellow communicated with an air outlet of the high-pressure centrifugal fan; the oxygen enriching filmassembly comprises a plurality of oxygen enriching films arranged on the air bellow in parallel, an air inlet of each oxygen enriching film is communicated with the air bellow, and an air outlet of each oxygen enriching film is communicated with the oxygen enriching air outlet pipeline; and the oxygen enriching air outlet pipeline is connected to an oxygen use pipeline by an oil-free vacuum pump.The invention assembles a full set of equipment into a whole, has compact structure, less space occupation, favorable effects of air filtration, oxygen enrichment and combustion support, long servicelife of oxygen enriching films, no oil stain and water in oxygen enriching air and high oxygen concentration and outlet air temperature, is beneficial to improving the temperature in a furnace, savesenergy, reduces consumption and reduces environmental pollution.

Description

technical field [0001] The invention relates to an oxygen enrichment device, in particular to a dry membrane oxygen enrichment device for oxygen enrichment and combustion support. Background technique [0002] Combustion is caused by high-energy collisions between combustible molecules in fuel and oxygen molecules, and the supply of oxygen determines whether the combustion process is fully completed. In a conventional air-supported combustion system, this high-energy collision is hindered by nitrogen molecules, which account for nearly four-fifths of the air composition and are non-combustible, reducing the chance of collisions between oxygen molecules and fuel combustible molecules, directly affecting combustion efficiency, and nitrogen It also absorbs a large amount of heat and discharges it in the exhaust gas, causing heat loss and wasting energy. [0003] The use of air with higher oxygen content than conventional air is called oxygen-enriched combustion. The purpose of...
