Abstract

The invention discloses an electric synergistic heat supply reforming reaction system which comprises a reforming reactor and an electric synergistic heat supply device, a flue gas convection area anda reforming reaction area are formed in the reforming reactor, and the flue gas convection area comprises a flue gas distribution device and a flue gas flow guide device. According to the electric synergistic heat supply reforming reaction system, by switching the heat contribution ratio of electric heating to flue gas heating, the reactor continuously and stably operates when either electric power or fuel gas is insufficient in supply; electric synergistic heat supply is adopted, the reforming reactor is high in starting speed, and the reactor can enter a stable production state within a fewminutes; convection smoke is generated in a non-open-fire catalytic combustion mode, the combustion temperature of catalytic combustion is low, and generation of NOx gas is remarkably reduced; meanwhile, an ultra-high-temperature area in the reactor is avoided, the requirement for reactor material selection is lowered, the service life of equipment is prolonged, and wide application prospects areachieved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an electrical cooperative heat supply reforming reaction system. Background technique [0002] Strong endothermic reactions are often involved in chemical production processes. In order to realize this highly endothermic process, the chemical industry usually uses the direct combustion of fossil fuels for heat supply. However, the high-temperature combustion of fossil fuels will not only produce a large amount of NOx gas, but also further aggravate the emission of greenhouse gases, causing irreversible global climate problems. In order to alleviate the adverse impact of chemical production on the global climate, the scientific community has proposed the concept of electrified production in the chemical industry. The use of electricity generated by renewable energy to provide energy for chemical industry production not only alleviates global climate problems, but also provides t...
