Abstract

The invention provides a micropower oxygen enrichment device and belongs to the technical field of garbage treatment. The technical problem to be solved is to provide the micropower oxygen enrichmentdevice; and on the premise of saving the operation cost, the oxygen content of the gas in a gas distribution system is increased and the garbage pyrolysis temperature under the oxygen-enriched environment is increased, so that the garbage treatment efficiency is improved. According to the technical scheme, the micropower oxygen enrichment device comprises a gas collecting cover and a plurality ofoxygen and nitrogen separation units which are sequentially connected in series; the oxygen and nitrogen separation units feed air into a gas guide pipe through an induced draft fan and an air supplypipe; a high-strength magnetic rob in the gas guide pipe generates a magnetic field; and through the magnetisability difference of nitrogen and oxygen, the air is layered in the gas guide pipe, the air is separated by an oxygen and nitrogen separation blocking pipe after flowing through the back end, the nitrogen-enriched air is discharged out of the gas guide pipe, the oxygen-enriched air entersthe next oxygen and nitrogen separation unit to further improve the oxygen purity or directly enter the gas collecting cover to be ready for use, and the gas collecting cover is a conical cover body.

Description

technical field

[0001] The micro-power oxygen-enriching device of the invention belongs to the technical field of garbage treatment, and specifically relates to the improvement of oxygen content in a low-temperature pyrolysis gas distribution system. Background technique

[0002] During the low-temperature pyrolysis process of waste, since the heat value of the waste itself is not high, the domestic waste relies on its own heat value to pyrolyze during the pyrolysis process, and the temperature can only reach below 200 degrees, which has a great impact on the efficiency of waste treatment. In the existing domestic waste treatment process, it is generally necessary to add auxiliary fuel or do pre-stage garbage sorting to maintain the normal operation of the waste treatment equipment, which also leads to high overall operating costs. After many years of experiments, we found that the most ideal thermal cracking temperature after carbonization of domestic waste is 300-380°C. At...
