Benefits of technology

The technical effects of the present invention are to provide a simple and cost-effective solution to overcome the problems of the prior art.

Problems solved by technology

Traditional water contains free oxygen, which can combine with metallic materials, resulting in oxidation.
Consequently, the acquisition and providing of nitrogen in the case of changes in volume of the storage fluid involve an enormously high expense and associated additional costs.
If a gas such as nitrogen (an inert gas) is used to prevent oxidation, oxygen may even result in low concentrations in oxidation processes, whereby plants and components in the heating system will be damaged and the operation or the entire plant may be impaired or halted.
By contrast with this, however, high operating costs occur when a gas covering with an inert gas such as nitrogen is required.
These facilities, in turn, are very costly in construction and operation.

Embodiment Construction

[0099]The figures show a buffer store according to the invention, which is denoted generally by reference number 10. It comprises a vessel housing 12, which stands on a base 14 and is closed with a lid 16.

[0100]The buffer store 10 according to the invention preferably comprises an insulation and a jacketing in the exemplary embodiment. It is preferably provided that the vessel housing 12 comprises an inner shell, forming the actual vessel, and an outer jacketing with an insulation to keep heat in the buffer store 10. In FIG. 2, the outer jacketing with the insulation is schematically given the reference number 36.

[0101]Moreover, it is provided that the bottom and / or the roof of the buffer store 10 or the base 14 and / or the lid 16 of the buffer store 10 are also insulated per the prior art, although this is not otherwise denoted in FIG. 2.

[0102]In its upper region, the vessel housing 12 comprises an equalization opening 18, by which the vessel housing 12 is fluidically connected to t...

Abstract

The present invention relates to a buffer store comprising a closed vessel housing for accommodating a storage fluid, in particular water, wherein the vessel housing has at least one inlet opening, for the filling of the vessel housing with the storage fluid, and at least one equalization opening, which fluidically connects the vessel housing to the surroundings and permits a fluidic equalization with the surroundings. According to the invention, a gas-tight cover is also provided in the interior of the vessel housing, which cover is capable of reliably protecting the storage fluid against mixing with other fluids, for example the ambient air.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to International Patent Application No. PCT / EP2018 / 071559, filed Aug. 8, 2018; which claims priority to German Patent Application No. 10 2017 118 952.1, filed Aug. 8, 2018.FIELD OF DISCLOSURE[0002]The invention relates to a buffer store, especially for heat storage.[0003]A buffer store according to the invention may involve, in particular, a buffer store which works in the “pressureless region” or under atmospheric pressure with an operating temperature of up to 95 degrees Celsius and which is designed in particular to operate with heating water as the storage fluid. The buffer store in particular can be part of a heating plant.[0004]The buffer store according to the invention may serve in particular for storing heat from biogas plants, biomass heating power stations, solar plants or other heat sources. Of course, excess heat of conventional power stations or incinerators can also be used to heat the stora...
