Problems solved by technology

[0018] Depend on figure 1 It can be seen that in the decomposition tank, the molecules at points a and b will be subject to different decomposition forces due to the different distances, resulting in uneven decomposition and reduced decomposition efficiency
[0019] The traditional planar electric field decomposition tank is used for desulfurization, although the desulfurization efficiency is high, but in the current polarization process, acid-base media must be used for desulfurization, and the discharge of acid-base solutions is also a heavy pollution behavior, which is expressly prohibited
Therefore, this kind of electrochemical desulfurization has not been widely used. How to use neutral medium to achieve the purpose of polarized desulfurization has become a hot spot for solving problems.

Abstract

The invention discloses a three-dimensional balanced electric field decomposition tank and a pre-desulphurization process of coals in the absence of acid-alkali medium. According to the three-dimensional balanced electric field decomposition tank, two comb-shaped electrode plates are arranged in the decomposition tank in a balanced manner, and a conventional planar electric field is three-dimensional, so as to ensure that the molecule at any point in the decomposition tank can be ionized by constant force and greatly improve the decomposition efficiency. The invention further provides a set of process for coals to perform desulphurization by utilizing the three-dimensional balanced electric field decomposition tank in the absence of acid-alkali medium, so that pyritic sulfur can realize decomposition / aggregation in a neutral medium so as to achieve the purpose of polarization desulfurization, the desulfurization efficiency is high, the pollution is avoided, the sulfur aggregated on the electrode plates can further be recycled and processed into by-products. The three-dimensional balanced electric field decomposition tank and the three-dimensional balanced electric field pre-desulphurization process can be used for coal desulphurization and can further be applied to other electrochemical industry fields.

Description

Technical field [0001] The invention relates to the field of electrochemistry, in particular to a three-dimensional balanced electric field decomposition tank and a coal pre-desulfurization process without acid-base medium under the action of the three-dimensional balanced electric field. Background technique [0002] In today's rapid economic development, the demand for energy is increasing. Coal, as the most traditional form of energy, will also be used in large quantities. However, the large amount of used coal has caused a problem that cannot be ignored. The sulfur dioxide (SO2) released during the combustion of coal 2 ) Has caused serious pollution to the environment, so that in many places, the use of coal has to be banned. This problem has seriously hindered the sustainable development of the national economy. [0003] In the 21st century, the contradiction between the development of the national economy and environmental protection has become very prominent. How to use coal...
