The figure shows a simplified view of a biogas plant.
The diagram shows a biogas plant, in which the range of processed raw materials was extended, the wastes of food industry ranging from meat processing, to recycling waste materials from supermarkets, hotels, etc.
The manufacturers of these kinds of products consume more energy than the farmers, we will modernize these plants for reasons of economy and efficiency. The use of a large capacity is possible due to the expansion of the feeding system with GHS pumps and grinders. The grinding system is making a significant contribution in processing, reliability and protection of pumps. The chopper serves as a cutting tool and a stone separator and gives a significant indicator of the efficiency by improving the homogenization of the medium.
The process of biogas production: In the beginning of the process, mixing pump feeds the fermenter with the mixture of solid and liquid substrates. Fermentation takes place with a dry matter content of about 5 - 15%. Pre-fermented substrate is transferred into the secondary fermenter, which gives an additional yield of biogas, due to a longer operating time.
Screw pump enhances flexibility of installation for return travel. He transfers the substrates and recycling of substances in different containers, even at higher solids. Before grinding, the system gives an even higher exit gas, which needs to be achieved. For example, methane obtained, is served in a cogeneration plant to generate electricity or thermal energy. The remaining biomass, which still has a residue of organic matter, dried. The substrates obtained are further re-use in agriculture. GHS pumps and grinders deserve great attention in this production.
