Abstract

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid by evaporation. The first container includes one or more openings through which a substance can be supplied to the fluid in the first container for breaking an emulsion or mixture of two or more components contained in the fluid and an exhaust through which the at least part of the one or more separated components can be exhausted.

First claim

The invention claimed is:

1. A device for separating a fluid component from a fluid, the device comprising:
a first container configured to contain the fluid, and separate at least a part of one or more components contained in the fluid from the fluid by evaporation, wherein the first container comprises:
one or more openings configured to receive a substance into the fluid in the first container for breaking an emulsion or mixture of two or more components contained in the fluid; and

a second container configured to separate at least a part of one or more components contained in the fluid from the fluid, wherein the second container comprises:
an exhaust through which the at least part of the one or more separated components can be exhausted, wherein
the first and the second container are interconnected by a throttle device disposed in a common wall between the first and the second container and configured to throttle a transfer of at least a part of the fluid from the first container into the second container or from the second container into the first container.

2. The device according to claim 1 , wherein
the first container comprises a heating device configured to increase a temperature of the fluid in order to enhance evaporation of the one or more components from the fluid, and
the heating device is controllable to maintain the temperature of the fluid above a threshold temperature or in a temperature range.

3. The device according to claim 2 , wherein
the heating device includes one or both of an electrical heating device or a heat exchanger for conducting a fluid such as a gas or a liquid to the first container, and
the heat exchanger is in contact with the first container to exchange heat with the fluid contained therein.

4. The device according to claim 1 , wherein
the first container comprises at least one perforated sheet, board or plate through which a gas or gas bubbles are supplied to the fluid to increase a surface of the fluid and an evaporation rate of one or more components of the fluid.

5. The device according to claim 1 , further comprising:
a heating device for heating the substance supplied to the fluid in the first container.

6. The device according to claim 1 , wherein
the throttle device comprises one or more of: a check valve, a drain valve, a filter, a membrane, an absorber for one or more components of the fluid, an opening in a wall between the first container and the second container, or an opening in a wall between the first container and the second container having an increasing or decreasing diameter.

7. The device according to claim 1 , wherein
the throttle device is adapted for actuation in dependence of a supply of a fluid such as compressed air to the first or second container so as to open to supply fluid from the first container to the second container or from the second container into the first container.

8. The device according to claim 1 , wherein
a void for receiving at least a part of the fluid is formed between an opening in the first container and an opening in the second container.

9. The device according to claim 1 , wherein
one or both of the first container or the second container comprises one or more of one or more filters or one or more baffle plates arranged across a flow direction of the fluid or a spiral flow path for the fluid in which at least a part of one or more components contained in the fluid are separated from the fluid, and
one or both of the first container or the second container further comprises an outlet to exhaust the separated at least a part of one or more components.

10. The device according to claim 1 , wherein
one or both of the first or the second container are arranged for containing the fluid and a substance supplied to one or both of the first or the second container by a supply connected to one or both of the first or the second container, respectively, wherein
the substance is an emulsion or mixture breaker configured to at least partially split an emulsion or mixture of two or more components included in the fluid into two or more separate components of the fluid upon contact with the substance.

11. The device according to claim 1 , wherein
one or both of the first or the second container comprises at least one filter, a membrane or substance arranged to separate one or more components from the fluid,
the filter, membrane or substance is configured to hold back one or more components of the fluid and let pass one or more other components of the fluid, and
one or both of the first container or the second container further comprises an outlet to exhaust the separated one or more components passed through the filter.

12. A system for separating a fluid component from
a fluid, comprising: a device according to claim 1 ; and
a container for compressed air, the container for compressed air being connected to the first or second container of the device by a valve arranged to supply air to the first or second container.

13. The system according to claim 12 , further comprising:
an air treatment unit, connected to the device, to supply air treated in the air treatment unit to the device, and configured to control supply of compressed air from the container for compressed air to the device as an emulsion or mixture breaking agent.

14. A method of separating one or more components from a fluid, comprising the acts of:
supplying the fluid into a first container;
separating at least a part of one or more components contained in the fluid from the fluid, wherein the separating includes:
supplying a substance for breaking an emulsion or mixture of two or more components contained in the fluid; and
evaporating and exhausting at least part of the one or more components via a second container connected to the first container, wherein
the first and the second container are interconnected by a throttle device disposed in a common wall between the first and the second container and configured to throttle a transfer of at least a part of the fluid from the first container into the second container or from the second container into the first container.
