CIRCULATION APPARATUS FOR COMPLETE MIX ANAEROBIC REACTION AND METHOD FOR CIRCULATION OF BIOGAS REACTION FEEDSTOCK

摘要

The present invention discloses a total mixed anaerobic reaction circulation device for methane, comprising a total mixed anaerobic reaction tank and a circulation tank, wherein the top portion of the total mixed anaerobic reaction tank is connected to the circulation tank via the overflow pipe; the lower portion of the circulation tank is connected to the lower portion of the anaerobic reaction tank via the transporting pipe and the material transporting pump; and the circulation tank is connected to the transporting pipe that supplies the methane reaction materials. The circulation tank is provided with the heat exchanger and the central cylinder therein; the overflow pipe is connected to the central cylinder; and the lower end of the central cylinder has the outlet pipe. The present invention also provides a circulation method of the methane reaction material. In the present invention, the use of the circulation tank simultaneously takes into account the functions such as addition and stirring of the methane reaction materials, heating of the methane reaction materials, adjustment of PH value, methane liquid recovery, etc. The total mixed anaerobic reaction circulation device for methane of the present invention is suitable for the large-scale industrialized methane project and can be popularized and used in cold areas.
