Definitions
- the invention relates to a swirl disk for a cyclone separator, which is used for separating liquid particles and solid particles from compressed gases, and claims the priority of German utility model 200 13 046, to which reference is made in terms of content.
- the compressed gases are introduced into a closed, cylindrical housing, the vortex chamber, and set in a vortex sinking flow.
- Different mechanisms of action occur between the liquid particles contained in the compressed gas and the solid particles.
- the " test particles move outwards within the developing vortex sinking and sink to the bottom, in particular due to their gravity, whereas the liquid particles hitting the cylindrical housing wall wet them and produce a liquid film, which is then drained downwards by appropriate design measures.
- Cyclone separators are simple in their construction, require little maintenance and are insensitive to contamination.
- Such guide means are always designed for a certain flow of compressed air. The best efficiency is achieved at the nominal flow for which the separator is designed.
- a cyclone separator is known in which the guide means are designed as interchangeable inserts, so that the characteristics can be largely adapted to the operating conditions in order to achieve the highest possible separation performance.
- the invention has for its object to provide a swirl disk for a cyclone separator, with which a dynamic adaptation to the respective operating conditions is possible, so that an adaptation takes place even with rapid changes in the operating conditions.
- the object is achieved in a generic cyclone separator with a swirl disk as a guide for generating a swirl sinking flow within a swirl chamber in that the swirl disk has a cutout with a tongue which is resilient against a compressed gas flow and which has the cutout as a function of the flowing amount of compressed gas opens more or less at a certain opening angle to the swirl chamber.
- the spring force of the tongue is dimensioned such that with a changing flow rate through the released opening, the compressed gas entering the swirl chamber always has a predetermined speed at which the best efficiency of excretion is achieved at least approximately.
- the required entry speed into the vertebral space is already known and is in the range between 14 and 18 m / s.
- the swirl disk consists of a resilient material with a spiral free cut, through which a segment-shaped resilient tongue is formed, which in turn opens an opening to the swirl chamber in the swirl disk, depending on the compressed air flowing through.
- Fig. 1 shows a section of a cyclone separator with a dynamic swirl disk
- Fig. 2 is a plan view of the swirl disk Fig. 3 shows the swirl disc with the tongue open.
- the cyclone separator I shown in Fig. 1 in its essential parts consists of a filter head 1 with an inlet of the pressurized gas A and an outlet B, a filter housing 2 which is sealingly connected to the filter head 1, a line protection 4, an outlet 5 and one Swirl disk 6, which is held in the filter head 1 by a screw thread 3.
- the compressed gas introduced into the inlet A into the filter head 1 flows through an opening 9, FIG. 3, through the dynamically acting swirl disk 6 and reaches a swirl chamber 10, which is formed by the filter housing 2 sealed against the filter head 1.
- the swirl disk 6 consists of a resilient material with a spiral free cut 7, as shown in FIG. 2, through which a segment-shaped resilient tongue 8 is formed.
- the force acting on the swirl disk 6 by the pressurized gas opens the tongue 8 depending on the flow rate of the pressurized gas at a predetermined opening angle ⁇ , FIG. 3, which is dependent on the spring constant of the swirl disk material and the length of the free cut.
- the parameters must be selected so that when the pressure gas flows through, a swirl speed of between 14 and 18 m / sec is set at a pressure of 7 bar.
- a cyclone separator I with a passage cross section of 1/2 "and a carbon swirl disk 6 with a material thickness of 0.3 mm requires a force of 0.009 bar to generate the required swirl speed.
- a force of 0.003 bar is exerted on the swirl disk 6.
- the opening 9 is closed by the tongue 8 so far that the swirl speed is maintained.
- the compressed gas flowing into the vortex chamber 10 is set into a vortex sinking flow.
- Liquid and solid particles are separated using centrifugal forces.
- the liquid particles from the compressed gas that hit the cylindrical inner wall of the filter housing 2 wet the latter and produce a liquid film that is drained downwards to the outlet 5.
- the solid particles also move outwards within the developing vortex sinking and sink to the ground mainly due to their gravity.
- the guide guard 4 prevents the cleaned compressed gas which flows further to the outlet B from entraining the water which is separated out.
