Abstract

The invention discloses a methanol reforming hydrogen production reactor with flow velocity distribution uniformity. The reactor comprises an upper cover plate and a lower cover plate, and further comprises the following three cavities: an evaporation cavity, wherein a through tank is arranged in the middle of a first graphite plate, an evaporation plate is arranged below the first graphite plate,and the evaporation cavity is formed in the through tank of the first graphite plate on the evaporation plate; a combustion cavity, wherein a through tank is arranged in the middle of a second graphite plate, a combustion reaction plate is arranged below the second graphite plate, and the combustion cavity is formed in the through tank of the second graphite plate on the combustion reaction plate; and a reforming reaction cavity, wherein a through tank is arranged in the middle of a third graphite plate, and two foam metal plates and a corrugated plate are arranged in the through tank. Each plate is provided with through holes, so that a methanol combustion reactant and a methanol steam reforming reactant respectively circulate through two respective paths. The reactor has the advantagesof good heat-conducting property, low density, light weight, good sealing property, uniform reactant flow velocity distribution, increase the reactant conversion rate, enhancement of the flow directionality, avoiding of turbulence and enhancement of the heat transfer and mass transfer effects.

Description

technical field [0001] The invention relates to a methanol reforming hydrogen production reactor, in particular to a methanol reforming hydrogen production reactor with uniform flow velocity distribution. [0002] technical background [0003] With the increasing consumption of fossil fuels and rising levels of greenhouse gases, my country is facing severe energy and environmental crises. Hydrogen energy has the advantages of high combustion calorific value, clean and pollution-free combustion products, and is recognized as one of the clean energy sources. Hydrogen fuel cell is one of the main ways to utilize hydrogen energy. It is not limited by the Carnot cycle, has a high energy conversion rate, and has low operating noise. It is widely used in the fields of mobile power sources and fixed base stations. [0004] The existing hydrogen storage methods usually use hydrogen storage tanks. However, its energy density is low, and the construction cost of hydrogen refueling stat...
