Description

Dust and water separator (cyclone) for smoke extraction systems RAS

The invention relates to a dust and water separation system in smoke extraction systems (RAS) according to the preamble of claim 1.

In particular, the invention relates to a filterless separation of foreign substances from the smoke gas intake of the RAS, without separating the smoke particles necessary for the purpose of early fire detection.

Furthermore, the invention promotes the further separation (filtration) of the smoke gases from dust and pollen, which otherwise lead to frequent false alarms.

Smoke extraction systems suck in air (smoke gas) from a pipe via a fan. This air is checked for smoke particles by a smoke detector. If smoke particles are detected, an alarm is issued and the fire department is alerted if necessary. The dust and other contaminants contained in the air that occur in industrial environments are problematic. In addition, the condensation had to be drained through a drip water drain hole.

The invention was intended to solve the problem of avoiding false alarms caused by dust and dirt and to replace the drip water drilling.

This object is achieved according to the invention by the characterizing features of claim 1.

Further features of the invention are contained in the subclaims.

The invention is described below with reference to the drawings using preferred embodiments as examples. The drawing shows:

Fig. 1 the dust and water separator.

The dust and water separator shown in Figure 1 contains a raw gas inlet (1), which is set into a round head section with a cover plate (2) at the side/middle. The head section merges seamlessly into a funnel (4) at the open end, the end of which is closed by a pipe section (5) with a cover cap (6).

In the middle of the funnel (4) there is a connecting pipe (7) which is pushed through the middle of the head part (2) and head part (3). The connecting pipe is closed at the upper end by

End cap (7) closed. The head sections (2) and (3) are connected with screws (8) and wing nuts (9) so that they can be removed for cleaning purposes. The clean gas outlet (1)0 is provided by a pipe section that is centrally mounted in the head section (3) but rotated 180 degrees to the pipe section (1).

The air sucked in by the RAS system flows into the dust and water separator through the raw gas inlet (1). Since the pipe (1) is inserted into the middle of the head section (2), the air flows directly into the center of the head section. Since no gas can escape except at the connecting pipe (7), the gas flows downwards along the funnel (4).

At the connecting pipe inlet (7) the gas must undergo a 180 degree gas flow change.

The heavier particles (dust, water) are thrown further into the area of the funnel ends/pipe (5) due to centrifugal forces and then remain there. The cleaned gas must then rise vertically upwards through the connecting pipe (7) before it can exit at the clean gas outlet (10).
