Dry-method natural gas desulphurization reactor

Abstract

The invention relates to a dry-method natural gas desulphurization reactor, and relates to a desulphurization reactor applied to the field of the chemical industry. The dry-method natural gas desulphurization reactor comprises a shell 1, a gas inlet 2, a gas outlet 3, catalyst unloading openings 4, an inlet diffuser 5, porous plates 6, a ceramic ball filter layer 7 and catalyst layers 8; the shell 1 is sequentially provided with the gas inlet 2, the gas diffuser 5, the porous plates 6, the ceramic ball filter layer 7, the catalyst layers 8 and the gas outlet 3 from bottom to top; the porous plates 6, the ceramic ball filter layer 7 and the catalyst layers 8 are respectively arranged inside the shell 1, and the catalyst unloading openings 4 are formed in the lower section of the side wall of the catalyst layers 8; the porous plates 6, the ceramic ball filter layer 7, the catalyst layers 8 and the catalyst unloading openings 4 form at least one reactor bed layer unit. By adopting the dry-method natural gas desulphurization reactor, the gas can be rapidly and uniformly distributed, the catalyst utilization rate and service life can be improved and prolonged, and the depth desulphurization of the natural gas can be facilitated.

Description

technical field [0001] The invention relates to a desulfurization reactor, in particular to a reactor for natural gas desulfurization, especially a dry natural gas desulfurization reactor. Background technique [0002] As a clean fuel, the development and utilization of natural gas has attracted widespread attention around the world. my country has abundant natural gas resources, but more than 1 / 3 of the natural gas currently produced in my country contains sulfur, so the development of the natural gas industry must first solve the problem of its purification. The domestic use of natural gas is increasing year by year, and the requirements for natural gas desulfurization technology are also increasing. To this end, the country has formulated relevant regulations to control the discharge of pollutants. This requires increased research and development of energy-saving, high-efficiency, and environmentally friendly new technology and equipment for natural gas purification and...

Problems solved by technology

The zinc oxide method is generally not limited by the raw material, and H can be removed finely at high temperature 2 S, often used as a checkpoint, the disadvantage is that it is sensitive to temperature requirements, the sulfur capacity at room temperature is very low, it cannot be recycled, and the price is high; the iron oxide method can be used for both coarse and fine removal, and the research on desulfurization at room temperature is progressing rapidly. Extremely high, high sulfur capacity, recyclable, cheap and easy-to-obtain raw materials, environmentally friendly, large market capacity, the disadvantage is that the side reaction is complicated at medium and high temperatures

[0006] There are many types of existing dry desulfurization reactors. The disadvantage is that the structure is too simple, the gas flow characteristics inside the reactor are not paid attention to, and the desulfurization efficiency is not high, which is not conducive to popularization and application.
