Biogas liquid and biogas residue are common wastes produced by biomass fermentation. Biogas liquid is rich in organic matter and nutrients, while biogas residue is rich in solid particles and fibers. In order to efficiently treat and utilize biogas slurry and biogas residue, Horizontal screw centrifuge Widely used in Treatment of biogas slurry and residue In process. This article will discuss the recumbent snail Centrifuge Its application and advantages in the treatment of biogas slurry and biogas residue.

1、 Characteristics of biogas slurry and biogas residue

Biogas liquid is a liquid waste produced by biological fermentation, which is rich in organic matter, nutrient elements and microorganisms. Biogas residue is the liquid that passes through Solid-liquid separation The resulting solid residue is rich in solid particles and fibers. These wastes have the characteristics of high humidity, high solid content and high viscosity.

2、 Application of Horizontal Screw Centrifuge in Treatment of Biogas Slurry

As a common and efficient physical treatment equipment, horizontal spiral centrifuge is widely used in the treatment of biogas slurry and residue. The following is the application mode and advantages of horizontal spiral centrifuge in biogas slurry and residue treatment.

1. Biogas slurry treatment: solid particles in biogas slurry can be separated from liquid by high-speed rotation and centrifugal force of horizontal spiral centrifuge. The centrifuge discharges the liquid phase by depositing solid particles on the wall of the centrifuge bowl. This solid-liquid separation can effectively improve the clarity of biogas slurry, reduce the content of suspended substances and solid particles, and thus reduce the load and cost of subsequent treatment.

2. Biogas residue treatment: The horizontal spiral centrifuge can separate and dehydrate the solid particles in the biogas slurry and residue. The solid particles are squeezed and discharged through the rotating action of the centrifuge, thus reducing the moisture content and volume in the biogas residue. This will help to reduce the transportation, treatment and disposal costs of biogas residues and improve the recovery and utilization rate of resources.

3. Efficient treatment: horizontal screw centrifuge has high treatment efficiency and dehydration effect. Its high-speed rotation and centrifugal force can quickly separate the liquid and solid phase in the biogas slurry and biogas residue, achieving high treatment efficiency.

The horizontal spiral centrifuge has important application and advantages in the treatment of biogas slurry and sludge. Through the process of solid-liquid separation and dehydration, the horizontal spiral centrifuge can effectively treat and separate the solid particles and suspended substances in the biogas slurry and residue, reduce environmental pollution, and realize the recovery and utilization of resources. Therefore, the reasonable application of horizontal screw centrifuge in the treatment of biogas slurry and biogas residue can improve the treatment efficiency, reduce the cost, and promote the sustainable development of biogas slurry and biogas residue treatment and resource utilization.
