Equipment for producing hydrogen from natural gas

Abstract

The invention discloses equipment for producing hydrogen from natural gas. The equipment comprises a high-temperature reaction furnace, a waste gas treatment tank and a carbon deposit discharging device, wherein a first conical cavity is formed in the lower part of the high-temperature reaction furnace; an air inlet pipe which is communicated with the interior of the high-temperature reaction furnace and is used for introducing the natural gas is arranged at the upper end of the high-temperature reaction furnace; a treatment cavity is formed in the waste gas treatment tank; a hydrogen collection pipe and a liquid injection pipe are arranged in the top wall of the treatment cavity; the liquid injection pipe is used for injecting alkaline liquid; a first connecting pipe is arranged at the upper end of the high-temperature reaction furnace; one end of the first connecting pipe is communicated with the interior of the high-temperature reaction furnace, and the other end of the first connecting pipe penetrates through the top wall of the treatment cavity, so as to extend into the bottom of the treatment cavity; the carbon deposit discharging device comprises a body; a collection cavityis formed in the body; an ignition device is arranged in the inner wall of the collection cavity; a second conical cavity is formed in the bottom of the collection cavity; a discharge chute communicated with the outside is formed in the bottom of the second conical cavity.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a natural gas hydrogen production equipment. Background technique [0002] The use of natural gas to produce hydrogen has the advantages of low cost and significant scale effect. Research and development of more advanced natural gas hydrogen production technology is an important guarantee to solve the problem of cheap hydrogen sources. As a high-quality and clean industrial energy, natural gas has important strategic significance in the process of energy development in my country. Because natural gas is not only an important fuel for people's daily life, but also a basic raw material for many chemical secondary products.

Problems solved by technology

[0003] Hydrogen production by pyrolysis of natural gas is the catalytic decomposition of natural gas into hydrogen and carbon at high temperature. This process is considered to be a transitional process between fossil fuels and renewable energy because it does not produce carbon dioxide. However, this process requires carbon deposition during production. However, it is easy to mix in oxygen when dealing with carbon deposits. Therefore, it will cause impurity in hydrogen, so it will cause safety accidents when using hydrogen.
