Description

Casing of a liquid spot separator for separating a liquid from a gas-liquid mixture.

The present invention relates to a housing of a "liquid separator for separating a liquid from a gas-liquid mixture.

In particular, the invention relates to a housing of a liquid separating device comprising an integrated liquid separating vessel as part of the housing for separating liquid from a gas compressed by means of a liquid-injected compressor or vacuum pump element.

It is known that, for such a compressor or vacuum pump element, liquid is injected into a compression chamber of the compressor or vacuum pump element for lubricating, cooling and / or sealing one or more rotors 20 arranged in this compression chamber.

This liquid is mixed with the gas drawn into the compression chamber and discharged together with the compressed gas from the compressor or the vacuum pump element.

In a liquid separation unit downstream of the liquid-injected compressor or vacuum pump element, liquid must be separated from the gas-liquid mixture which is discharged from such a liquid-injected compressor or vacuum pump element. a consumer or consumer network. to provide with mainly

BE2019 / 5012 liquid-free compressed gas or compressed gas with at least a significantly reduced liquid content.

The separated liquid is then recovered and diverted from the

Fill separator to the liquid injected compressor or vacuum pump element to be reinjected into the compression chamber.

The liquid separator is typically a unit comprising a vessel separate from the liquid injected compressor or vacuum pump element, the vessel configured to separate and store liquid from the gas-liquid mixture.

An inlet of the liquid separator is connected by a pipe to an outlet for the compressed gas-liquid mixture of the. liquid injected compressor or vacuum pump element. An outlet of the liquid separator for liquid-free or liquid-low gas is connected to either a consumer network or application, or additional ..> Lrooma. ^. "Where se aoparatu.u.reen.neden.need further treatment of the liquid-free or liquid-low gas.

Examples of individual prior art liquid separators can be found, for example, in WO 2018/134758.

However, these prior art liquid shearers exhibit some specific drawbacks.

O

The first disadvantage of BE2019 / 5012 lies in the considerable overall dimensions of the liquid separator, mainly because of the size of the vessel.

For example, if the liquid injected into the compression chamber is oil, this oil is subject to relatively rapid oxidation degradation due to significant heat generated in the compressor or vacuum pump element upon compression of the gas. For this reason, the oil volume maintained in a compressor or vacuum pump installation and, therefore, the size of the tank, should be kept as large as possible to decrease the oil / gas contact area ratio to this oil volume. In this way, the 1.5 frequency of oil changes can be reduced, reducing downtimes of the compressor or vacuum pump system for oil changes.

If the size of the liquid separator tank is reduced without decreasing the volume of the liquid provided in the compressor or vacuum pump installation so that a liquid fill level of the liquid separator vessel increases, there is a risk of liquid entrainment of the liquid in the liquid separator vessel to the liquid-free or liquid-free gas obtained due to turbulences in this liquid and at the most contact surface between liquid and gas, as a result of strong input of the gas-liquid mixture into the liquid separator tank, possible pressure fluctuations in the liquid separator tank, and / or strong evacuation of liquid from the liquid separator tank.

BE2019 / 5012

A second drawback is the significant number of components in the overall compressor or vacuum pump installation that have a separate liquid separator, primarily because of the number of piping to connect different equipment units downstream of the compressor or vacuum pump element, including the liquid separator.

In addition, pressure drops across the pipes increase with the number of bends and the length of these pipes.

Finally, the pipes are usually the weakest components of the overall compressor ·· or vacuum pump installation in terms of mechanical strength, corrosion and leak tightness, especially in places where the pipes fit the different equipment units, which have specific sealing and insulation requirements. of these pipes.

When the line between the compressor or vacuum pump element and the liquid separator of the compressor or vacuum pump installation does not securely connect these two components as a single unit, it may be difficult to move the compressor or vacuum pump installation as a whole, implying that the compressor - whether a vacuum pump installation must be dismantled into all its components during transport.

For these reasons, there is a need for the compressor or vacuum pump element and further downstream equipment units, such as components of a compressor or

BE2019 / 5012 vacuum pump installation, which can be spatially brought closer together or even integrate functions of these components into a more limited number of components compared to the number of components required in conventional compressor installations in which all components are spatially separated from each other.

For example, compressor or vacuum pump installatles have been developed that integrate the liquid-injected compressor or vacuum pump element and the liquid separator into one common housing comprising a body composed of a single block.

Examples of this type of integrated compressor or vacuum pump installations are known, for example, from the

European patent EP 2,820,307.

However, integrating both the compressor or vacuum pump element and the liquid separator into one common housing reduces overall modularity and flexibility in the composition of the compressor or vacuum pump installation since the compressor or vacuum pump element and liquid separator cannot be separated and separated.

This places some restrictions on adapting the size of the fluid separator to a load and related fluid requirements of the fluid separator. compressor or vacuum pump element, a possible mandatory adjustment of the fluid separator to operate under stricter government regulations, and / or a replacement of

BE2019 / 5012 only one of the liquid separator or the compressor ··· or vacuum pump element when one of these components fails or fails.

In addition, the integration of too many components of the compressor or vacuum pump installation can. one small common housing composed of a single block decreases the accessibility of the components in the housing, and thereby the ease of maintenance of these components.

In addition, the compressor or vacuum pump element with its shape and. often as one of the first components in. the housing block is attached, since this shape is determined by the rotors included in this compression chamber.

Consequently, space in the housing block that remains after capturing the shape and position of the compressor or vacuum pump element in the housing block is used to record the position and shape of the liquid separator, often leading to a non-symmetrical internal shape of the liquid separator vessel, as illustrated by the liquid separator vessel in European Patent EP 2,820,307, resulting in non-optimal separation of liquid from the gas-liquid mixture in the liquid separator vessel.

Finally, the integration of many components into one small

BE2019 / 5012

The aim of the present invention is to provide a solution to one or more of the aforementioned and / or other disadvantages.

To this end, the invention relates to a housing of a liquid separating device for separating a liquid from a gas-liquid mixture, the housing comprising an inlet for the gas-liquid mixture and a set of integrated components 10, the set of integrated components comprising a liquid separator vessel is configured to separate liquid from the gas-liquid mixture, the liquid separator vessel comprising a gas-liquid mixture supply port, a liquid outlet port, and a gas outlet port, the set of integrated components further comprising a set of channels, a wall of each channel is part of the enclosure, where the set of channels includes:

an inlet channel configured to pass the gas-liquid mixture from the inlet of the housing to the supply port of the liquid separator vessel; and

an outlet channel configured to divert gas from the gas outlet port away from the liquid separator vessel, characterized in that the housing comprises at least two opposed housing pieces configured to be hermetically sealed together

BE2019 / 5012 a sealing line located in a sealing surface.

By "opposed casing pieces" is meant that the casing pieces are essentially located on opposite sides of the sealing surface.

An advantage of the housing according to the invention is that the number of components in the entire compressor installation is reduced by eliminating the need for separate inlets. outlet pipes for connecting the liquid separator to the compressor or vacuum pump element respectively !! j k. the consumer network / application or additional downstream equipment to further treat the purified gas-liquid mixture obtained from the liquid separator.

Since the inlet and outlet channels are integrated as fixed channels, the wall of these channels being part of the housing according to the invention, they are better protected against external influences from the environment, which gives additional mechanical strength to the overall compressor or vacuum pump installation. and makes the compressor or vacuum pump installation less susceptible to corrosion and / or leakage.

In addition, the integrated channels can be arranged to blend seamlessly into the liquid separator vessel, providing leak-sensitive fittings required to

BE2019 / 5012 to fix conventional non-integrated pipes on the liquid separator vessel.

As an additional advantage, the integrated ducts can be arranged in the housing in such a way that they are as short as possible and have as few bends as possible, in order to prevent excessive pressure drops and to achieve an optimal reduction in the size of the entire compressor or vacuum pump installation.

The housing assembly in at least two opposed housing pieces facilitates the manufacture of this housing, even if the housing comprises multiple components, possibly with complex and / or irregular shapes, by conventional manufacturing techniques, such as injection molding.

As an additional benefit, the components mounted in the housing are more easily accessible, and therefore easier to maintain and / or replace, after the housing has been opened, by separating the at least two opposite housing pieces along the sealing surface, which sealing surface is preferably a plane.

BE2019 / 5012 liquid separator vessel through the liquid outlet port of the liquid separator vessel.

The advantage that the integration of the liquid storage reservoir in the housing of this preferred embodiment entails is a further reduction in the overall size of the compressor or vacuum pump.

In addition, the liquid stored in the liquid storage reservoir is separated from liquid in the liquid separator vessel by a wall of the liquid separator vessel and is in fluid communication only with the liquid in the liquid separator vessel through the liquid outlet port of the liquid separator vessel.

Since the wall of the liquid separator vessel serves as a sort of baffle between the liquid in the liquid separator vessel and the liquid in the liquid storage reservoir, the aforementioned liquid in the liquid storage reservoir is less susceptible to turbulences in the liquid in the liquid separator vessel which may be caused by vigorous introduction of the gas-liquid mixture through the supply port in the liquid separator vessel and / or pressure fluctuations in the liquid separator vessel. In this way, excessive entrainment of liquid droplets with the purified gas liquid mixture leaving the liquid separator vessel through the gas outlet port can be significantly reduced or even
