Abstract

Reservoir for liquefied petroleum gas, with a withdrawal port for the fixed supply of a consumer with heating energy, characterized by at least one other Tapping port (15) connected to mobile consumer units (23) is connectable.

Description

The The present invention relates to a liquid gas storage container having a withdrawal port for the fixed supply of a consumer with heating energy.

Reservoirs for storing LPG are well known in the art. That's how it describes German utility model 297 13 984.3 a liquefied gas tank, especially for underground storage. The storage tank has in each case a connection for filling and a connection for removing the liquefied gas.

Furthermore, storage containers for storage and removal of gaseous and liquid cryogenic energy carriers for motor vehicles are known. For example, the DE 199 45 462 A1 a method in which the removal from the gas phase and the liquid phase from separate tanks via a respective extraction line, and these extraction lines are merged into a line leading to the consumer of the cryogenic medium. Such tanks are used in motor vehicles, which are operated with liquefied natural gas be. They are exposed to very high pressures and must be able to withstand very low temperatures. These natural gas tanks are therefore very expensive to manufacture and difficult to handle in everyday operations.

The EP 0 779 469 B1 describes a device for supplying a consumer with cryofuel from a cryotank. Again, the requirements that are placed on the material used for the production of the cryogenic tank, completely different than for liquefied gas tanks.

From the DE 103 60 936 B4 For example, a device is known which connects a plurality of fuel tanks, in particular LPG tanks, to allow fuel flow between the tanks. This device is merely for injecting LPG into an automotive engine and is not suitable for the storage of LPG for heating purposes.

The known reservoir have proven themselves in their respective field of application However, with the disadvantage that a multiple use of the stored energy source is impossible.

It The object of the present invention is to provide a storage container create a flexible distribution of the stored in him energy source allows different consumers for different purposes, doing so cost-effectively and lowering operating costs.

These The object is achieved by the feature specified in patent claim 1 solved. Advantageous embodiments The invention are the subject of the dependent claims.

Of the Inventive reservoir for liquefied gas has a withdrawal port for fixed supply to a consumer with heating energy and can with at least one other extraction connection be connected to mobile consumer units.

Thereby can the liquefied gas be delivered to different different consumption units. The utilization is increased and thus reduced the operating cost of the storage tank.

In an advantageous embodiment of the storage container according to the invention it is provided that the further extraction connection via a control unit solvable can be connected to external, mobile consumer units, it being advantageous if the further removal connection is independent of the first removal port can be controlled.

Of the further removal connection is detachable with separate, mobile consumption units connectable. This can be done by the fixed consumer, namely a heating system, independent consumers, For example, motor vehicles to be supplied with LPG. Of the Operation of the heating system is not affected.

In a preferred embodiment of the storage container according to the invention associated with the further removal connection a documentation means, that's about the amount of liquefied gas taken from the further removal connection is documented and logged. This can be taken from the respective consumers Liquefied gas for different Billing purposes are determined and calculated. The documentation tool can for example, the storage tank withdrawn amount of liquefied gas by volume or by weight. By capturing the discharged liquid gas the stocking in the storage container can be managed.

A Another object is to provide a reservoir for a heating system, for more Consumer is usable.

This object is achieved by the features specified in claim 7, in particular by a reservoir with a first extraction port for the removal of LPG for permanent power to a stationary consumer to generate heat, the is used by means of at least one further extraction connection for the supply of external, mobile consumers with LPG.

The Invention will be described below with reference to an exemplary embodiment with reference to the attached Drawing closer explained.

The single figure shows the schematic representation of a reservoir according to the invention, the for one dual operating mode can be used.

The illustrated reservoir 10 is pressure-resistant and designed for pressures of approx. 8 to 10 bar. He may be a ground-covered cylindrical hollow body, as he in the German utility model 297 13 984.3 has been described.

The storage tank 10 is with a withdrawal port 11 provided by a supply line 12 with a stationary consumer 13 connected is. The stationary consumer 13 may be, for example, a heating system for household use, a cogeneration plant or the like. About the supply line 12 becomes the consumer 13 permanently with LPG 14 provided.

The storage tank 10 is according to the invention with a further removal connection 15 Mistake. The further removal connection 15 is a second supply line 16 assigned independently of the first supply line 12 can be operated in dual operating mode. This can be particularly beneficial if the consumer 13 operated in regions in which the supply of liquefied gas can be ensured only via such reservoirs.

Furthermore, climatic conditions can lead to an autonomous supply of LPG to survive. With the present invention, two separate consumer systems from the reservoir 10 be supplied cost-efficiently, quickly and safely with the necessary LPG.

In dual mode of operation, the first extraction port can be used 11 the stationary consumer 13 and via the further extraction connection 15 at the same time a mobile consumption unit 23 from the reservoir 10 be supplied. The respective removal is by a control unit 17 regulated.

The control unit 17 includes shut-off and control means, the unwanted and uncontrolled escape of the in the reservoir 10 stored liquefied gas 14 prevent. The removal of liquefied gas 14 can do this via the control unit 17 as needed at the respective withdrawal connection 11 or 15 respectively.

The control unit 17 includes a documentation tool 18 with which the removal of liquefied gas 14 from the reservoir 10 can be controlled. The removal of liquefied gas 14 over each withdrawal port 11 or 15 is logged separately.

In order to Is it possible, the respective removal separately from individual consumers assigned.

The documentation tool 18 can as one from the reservoir 10 be formed independent module and detects the via the extraction ports 11 or 15 taken amount of liquefied gas 14 by weight or volume. The documentation tool 18 does not necessarily have the control unit 17 It can also be set up externally and connected via data transmission lines.

The second supply line 16 is a filling connection line 19 assigned. The filling connection line 19 has at its free end a valve assembly 20 on. The valve arrangement 20 can with a filler neck 21 a tank 22 For example, a motor vehicle or other mobile consumer 23 to be brought into contact. The connection can be made according to the key / lock principle to prevent unwanted escape of LPG.

It can be provided to the mobile consumer 23 only to refuel when the valve assembly 20 is unlocked. At the same time, the control unit 17 sure that in case of improper connection between the filling connection line 19 and the filler neck 21 no liquefied gas 14 from the reservoir 10 to the further removal connection 15 is directed.
