Definitions
- the invention relates to a method for operating a biogas plant having the features of claim 1 and to a biogas plant having the features of claim 8.
- the recirculation of the percolate can be used to regulate the temperature, and it is possible to add additives for process optimization.
- Dry fermentation is necessary, for example, for very dry or particularly fibrous fermentation substrates.
- batch operation denotes a process principle in which no further material is added or removed during the fermentation process Fermenter, the fermenter is completely emptied and then refilled.
- the disadvantage of batch operation is that the operation of the biogas fermenter must at least then be interrupted, if the fermenter room has to be emptied and filled with fresh fermentation substrate.
- a cogeneration plant serving to generate electricity and / or heat
- a plurality of fermentation tanks are operated at different times in the biogas plant.
- Biogas fermenter must be stopped. Because, as described above, then first the already fermented biomass must be removed from the respective biogas fermenter, filled the fresh biomass in the biogas digester and the
- Percolation stands to be used. This process is controlled by the methane gas content. Although a, according to DE 10 2010 028 707 A1 constructed biogas plant, Biogas with constant and high methane content available, however, reduces the efficiency of the exhaust air operation during the beginning of percolation
- Bioreactors in the gas space of one or more bioreactors is passed.
- the measured values of H2S, CO2, CH4 and O2 from all bioreactors are constantly queried and the exchange between two and more bioreactors regulated.
- Pressure and sulfur are used as values to determine when a bioreactor is ready for replacement with one or more other bioreactors.
- the procedure specified in D4 indicates an increase in the efficiency of a biogas plant, but it also requires a considerable use of measuring and control technology.
- the object of the present invention is therefore to provide a method for operating a biogas plant and a biogas plant operated in this manner, in which the efficiency in batch operation is significantly increased using structurally simple means and the continuous output of usable biogas is improved.
- the invention relates to a method for operating a biogas plant according to the principle of dry fermentation with a plurality of biogas digesters, which are driven or operated in batch mode. At least one of the biogas fermenters has just recently been loaded with fresh biomass, and at least one of the remaining biogas digesters is in a state in which it is entering methane-containing, ie better usable, biogas produced.
- the following method steps are provided:
- Biogas fermenter with at least one of the other biogas producing biogas fermenters,
- Biogas fermenter after a certain period of time.
- the biogas from the freshly loaded biogas fermenter is converted into a single or at the same time into several other, currently operated and usable biogas biogas with high methane concentration-generating
- Biogas fermenter recycled By mixing the lean gas with the methane-containing biogas of one or more of the remaining biogas digester, the variation of the methane concentration in the mixed biogas from all biogas digesters and the rate of change of the methane concentration can be reduced in a simple manner.
- the biogas produced in the biogas fermenters is fed to a CHP with gas engine.
- the gas engine is preceded by a so-called gas mixer, which mixes the biogas with the necessary air for combustion and ensures at different methane concentrations in the biogas for a combustible biogas / air mixture.
- gas mixers have a certain inertia, so that in the event of rapid and / or strong fluctuations in the methane concentration in the biogas, under certain circumstances, a biogas / air mixture which is no longer combustible is fed to the gas engine and the gas engine dies.
- Variation of the methane concentration is reduced and in addition, the change of the methane concentration in the mixed biogas flows from all biogas fermenters slower, so that the gas mixer can always provide a combustible biogas / air mixture for the gas engine despite its inertia.
- the period of time determined depends on the size of the biogas plant or the number of individual biogas fermenters, the size of the individual biogas fermenters and / or the type of biomass to be fermented and is based on empirical values. The period is chosen so that after switched biogas utilization devices, eg. B. CHP with gas engine, gas treatment equipment, etc., can be supplied continuously with recyclable biogas.
- Biogas mixture from the freshly loaded biogas fermenter takes place, so in one
- Control device deposited that the time period parameterizable, i. manually changeable by an operator or automatically by a technical device is. For example, the length of time, depending on the size of the entire biogas plant - number of biogas digesters - and depending on the size of the biogas digester changed or
- the biogas plant can be operated very flexible and efficient.
- the biogas plant can be operated even more flexibly if the specific period of time can also be influenced by further parameters and / or manually by an operator while the biogas plant is in operation.
- concentration of certain proportions of biogas in particular the methane concentration, could be measured and, depending on this, the specific period shortened or extended in order to optimize the operation time and / or quality.
- Biogas fermenter an oxygen-free or at least as low oxygen scavenging gas is introduced into the biogas fermenter.
- the biogas fermenter is purged before opening until it is ensured that when the biogas fermenter is opened by the incoming air no explosive biogas / air mixture can arise more. The risk of accidents is considerably reduced.
- the process is particularly simple, since the transfer of the
- Biogas mixtures of the at least one freshly loaded biogas fermenter by a pressure gradient takes place, which results in the mere addition of biogas fermenter loaded with fresh biomass - ambient pressure - with the other biogas fermenters - slightly increased pressure by the biogas produced. As a result, no further aids, in particular no funding necessary.
- the methane concentration in the biogas mixture from all biogas fermenters in a biogas collecting line is measured to determine the specific period of time.
- Biogas fermenter is chosen so that the methane concentration in the
- Biogas manifold does not fall below a predetermined by the downstream biogas utilization device minimum value. If the methane concentration in the biogas collecting line is measured continuously or at intervals, a particularly accurate and efficient operation of the entire biogas plant is achieved since all measures for transferring the biogas can also be carried out or controlled as a function of the measured methane concentration.
- the at least one freshly loaded biogas fermenter connected not only with a single, but with several of the remaining biogas fermenter, so that its biogas mixture is converted according to several biogas digesters.
- the efficiency of the process can be significantly increased again.
- a biogas plant which is suitable for carrying out the method described above has a plurality of biogas fermenters which operate on the principle of dry fermentation, each biogas fermenter having at least one
- Biogas plant via at least one gas transfer line with a valve device through which the biogas outlet of a Biogasfermenters with the gas inlet of another is connectable for a certain period of time.
- This biogas plant is advantageously suitable to increase the methane content of the lean gas of a freshly loaded biogas fermenter in a particularly simple manner and the
- Biogas plant is extended.
- a particularly advantageous embodiment of the biogas plant according to the invention has a measuring device for detecting the methane concentration in a biogas collecting line in which the biogas from all biogas digesters together.
- control device prefferably controls and / or regulate the connection of the gas outlet of the at least one freshly loaded biogas fermenter to the gas inlet of at least one of the remaining biogas fermenters by means of the gas transfer line.
- control / regulation only depending on the particular
- the methane concentration in the biogas collecting line can be taken into account for this purpose.
- Biogas fermenters as far apart as possible. In particular, these can be arranged at opposite ends of the respective biogas fermenter. As a result, it can be achieved that the methane enriched lean gas in addition to prolonged stay must also deny the longest possible transport route.
- the gas inlet can be arranged in the bottom region of the respective biogas fermenter. As a result, the lean gas must flow through the biomass and the
- Dwell time of the lean gas in the respective biogas fermenter is extended. Consequently, a particularly effective mixing results between lean gas and biogas produced in the biogas fermenter with high methane concentration.
