The invention discloses a
biogas cold-
drying dehydrator with adjustable
biogas outlet temperature, which belongs to the technical field of
biogas dehydration, and comprises a plurality of cold-
drying devices which are sequentially connected in series, the lower parts of the plurality of cold-
drying devices are fixed on the ground through a support frame, the cold-drying devices are communicated through communicating pipes, the outer side of the cold-drying device at the gas inlet end is communicated with a biogas inlet
pipe, and the outer side of the biogas inlet
pipe is communicated with a biogas outlet
pipe. According to the invention, a modular
assembly design is adopted, flexible adjustment can be carried out according to the biogas flow demand, the installation efficiency and adaptability of the equipment are improved, the device is suitable for biogas treatment systems of different scales, and the device is convenient to use, high in practicability and easy to popularize and apply. The
system has remarkable advantages in the aspects of
energy conservation, efficiency, stability and intelligence, provides an efficient, economical and easy-to-maintain biogas treatment solution, and has a wide application prospect in the novel technical fields of full-amount recycling of
feces and the like.
