Abstract： |
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. |
