DESCRIPTION:
BRIEF SUMMARY
This invention relates to an apparatus for regulation of gas feed for gas consumption from a source with a variable production.
It is known in the art to provide a gas regulator having a gas supply which is constantly under high pressure, the regulator serving a consumer requiring a constant gas supply under relatively low pressure. Such a regulator is disclosed in Miller U.S. Pat. No. 1,263,919 granted Apr. 23, 1918.
The object of the invention is to make optimal utilization of gas for consumption in such cases, where the supply of gas varies, for instance in anaerobic fermentation of manure in farms, methane gas being formed. This gas can for instance be combusted in a combustion engine for production of electrical current either directly or via an accumulator tank, which then serves as a gas buffer. According to the invention there is also provided an overpressure protection for the gas buffer and a preset regulation of the gas pressure to the consumer. These objects are met, according to the invention, by the aid of an apparatus, characterized by two chambers communicating in the lower ends, at least one of the chambers being closed in the upper end, the lower part of the chambers being filled with a liquid when in operation, the first chamber being provided with a gas inlet from said gas production source and with a gas outlet to said gas production source and with a gas outlet to said gas consumer, means regulated by the liquid level being provided in the second chamber, for starting and shutting of the gas consumer, which can be a motor, a gas combustion boiler or a gas pipe.
When the produced gas contains condensable or precipitable liquid, as is the case when producing methane by fermentation of manure, the liquid volume will increase in said chambers, by water being separated from the gas. This excess of water must be discharged, which can be done by providing the apparatus with a weit outlet, located outside the chambers, communicating with their lower part, the weir outlet being located on the same level as the starting level of said means.
If the gas production would occasionally be larger than the consumption, a gas overpressure discharge outlet may be arranged, extending from the upper part of the second chamber above the level of starting of the said means. Such a gas overpressure discharge outlet, which preferably leads out into the free air or to a torch, has an object, when for instance methane is produced; to prevent too high gas pressures from being built up on the system and dangerous gas concentrations from being formed indoors.
In some gas production, as the production of methane gas by fermentation of manure, the gas is not only followed by water vapour but also by solid particles. These two products are separated from the gas by providing said gas inlet opening a substantial way down in said first chamber, whilst the gas outlet to the consumer extends from the upper part of this chamber above the opening of the outlet. In this way water vapour is condensed from the gas phase and is combined with the water in the chamber. The solid particles are also separated and are captured by the water, whilst the gas is discharged through said gas outlet.
The invention shall be described more in detail in the following, reference being made to the enclosed drawing, which shows, by way of example, an embodiment of the present apparatus. To be more exact,
FIG. 1 shows a longitudinal sectional view through the chambers, that are included in the apparatus and
FIG. 2 a cross sectional view, as seen from above.
In FIG. 1, 1 denotes a first vertical pipe and 2 a second vertical pipe, constituting the chambers, which are included in the apparatus. Gas, containing water vapour and solid particles, enters through a line 3, which opens a substantial way down in the pipe 1. Water condensate drips from the opening of the line 3 down in an amount of water 4, which is present in the pipe, and which also captures separated, solid particles. Gas freed from water vapour and solid particles, is discharged throug
