Abstract: A clock generation apparatus has a delay circuit, a phase selection circuit, and a phase measurement circuit. The delay circuit outputs a first signal that is a delayed version of an input signal. The phase selection circuit receives the input signal and one or more phase-shifted versions of the input signal and outputs a second signal that is a phase-shifted version of the input signal. The phase measurement circuit compares the phases of the first signal and the second signal and provides a first output that controls phase of the second signal relative to the input signal. The phase measurement circuit also provides a second output that controls a delay applied by the delay circuit to the input signal to generate the first signal.

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.
