Working principle and application of biogas slurry separator

Biogas separator is a high-efficiency solid-liquid separation equipment used in farms, biogas projects and other fields. Its main function is to separate the solid and liquid substances in biogas for subsequent resource utilization and environmental governance. The following is an introduction to the working principle and application of biogas separator: 1. Working principle: Biogas separator usually uses screw extrusion or centrifugal separation technology for solid-liquid separation. During the working process, the fermented biogas enters the separator through the feed port. Under the action of the screw shaft or centrifugal force, the solid matter is compressed and discharged, while the liquid flows out through the separator to achieve solid-liquid separation. 1. Screw extrusion separator: The centrifugal force generated by the rotation of the screw shaft is used to push the solid matter to the outlet, and the liquid flows out through the screen. 2. Centrifugal separator: The solid matter is separated from the liquid by the centrifugal force generated by high-speed rotation. 2. Application field: 1. Farm: After the fecal sewage generated by the farm is fermented in the biogas tank, the biogas separator is used for solid-liquid separation. The separated solid organic fertilizer can be used for fertilization or as feed, and the liquid can be further processed or discharged. 2. Biogas project: The biogas slurry produced in the biogas project can be used as organic fertilizer after being separated by the separator, and the liquid part can be returned to the biogas tank or treated. 3. Agricultural waste treatment: Agricultural waste such as drug residue, starch residue, sauce residue, etc., can be treated by the biogas slurry separator to improve the utilization efficiency of solid matter and reduce environmental pollution. 4. Kitchen waste treatment: Grease, residue, etc. in kitchen waste can be separated by the biogas slurry separator for resource utilization. III. Advantages and characteristics: 1. Compact structure, small footprint, easy installation and maintenance. 2. High separation efficiency, strong processing capacity and strong adaptability. 3. No external power is required, and the operating cost is low. 4. High degree of automation and simple operation.
