Dynamic micromixer

Abstract

The invention relates to a method of the fine volume-controlled blending of substrates in anaerobic reactors with flat bottoms, by unchangeable or changeable surface-like blowing in of gas close to the reactor bottom, wherein, the blowing in of the gas substantially covers every unit of whole the bottom, a dynamically changing control is carried out by these units to the whole or part of the gas entering process. Thereby, a local micro-turbulence is caused t at each gas entering point of volume of the reactor.

Description

technical field [0001] The fields of application covered by this patent application relate to the mixing of the contents of large vessels to optimize biochemical operations in anaerobic processes, especially for the formation of biogas. Biogas formation processes of this type are increasingly being established and operated, which allow the biodecomposition of organic materials by forming biogas (mainly methane) while generating energy. This application involves the generation of gases from waste-water containing feedstocks that will incorporate organic residues (e.g. applicants according to EP0998430 (Skj ldgas)-FFF-system (see EP1419995 solid-fluid-fermentation process)) decomposed waste water purification to specialized anaerobic fermentation for decomposition process of plants such as corn, rye, grass and other similar, and others Similar to the process, these plants are often ensiled perennially to feed biogas generators as so-called NOWARO (renewable raw material). In ...

Problems solved by technology

[0028] n) Methane bacteria are sensitive to temperature changes. Therefore, when the high temperature > 50°C formed under the heating device (such as a heating tube) and the gas blown in will be unfavorable to them, or cause their death - this negative The effect is more obvious
