The present invention relates to a
methane and
oxygen pre-mix device, mainly consists of a casing, a gas distributed
system, a heat exchange
system and a multiorifice gas distribution plate; the gas distributed
system adopts the
rotational flow or the circular flow gas distributed system; the
rotational flow gas distributed system consists of a
methane air intake system, an
oxygen air intake system, an upper
distributor and a lower
distributor; the circular flow gas distributed system consists of center feed pipes, cross feed pipes and ring gas
distributor of the
methane and the
oxygen; the heat exchange system consists of an upper separator, a lower separator, a centre internal
pipe, an external
pipe, a
metal fin, a heat exchange medium inlet
pipe and a heat exchange medium outlet pipe; via the gas distributed system, the methane and the oxygen have a preliminary mixture in a smaller space, then by the
stimulant fluidized bed consisting of the centre internal pipe, the external pipe and the
metal fin, circuitously flowing upwards, achieving a
molecular level mixture at the exit. The present invention effectively increases the pre-mix effect and guarantees the inflaming retarding and explosion prevention of the pre-mix chamber, having a good function in the industry of methane
partial oxidation to
syngas.
