Abstract: The present invention belongs to the technical field of hydrate application, and proposes an electric field-based CO2 capture apparatus by a hydrate method and a method therefor. Small particles of hydrate are generated by incoming seawater and incoming hydrate former at low temperature and high pressure. After flowing through the electric field, the particles are quickly formed, and then separated, dried and compressed efficiently by a solid-liquid separation chamber. Finally, hydrate blocks are produced. The combination of a stirring method, a spraying method and an external electric field can effectively solve the characteristics of slow hydrate formation and long cycle. The solid-liquid separation chamber can be designed to efficiently filter out the hydrate particles and prevent a filter plate from blocking. The use of heat exchange chambers in many places make the cooling amount in the discharged waste recycled, greatly thereby improving the utilization efficiency of energy and economic benefits.
