Definitions
- the invention relates to the removal of dust-like, gaseous, mist-like or liquid substances from a gas stream to be purified in a device and a corresponding method.
- DE 103 35 194 A1 shows a pre-separator for the removal of impurities from the air in an air intake system of an automotive engine.
- US 4 629 481 A shows a modular separation unit for separating a liquid from a gas-liquid mixture.
- EP 1 458 490 B1 shows a cyclone separator, with a tube and a
- Such apparatus may be needed in particular in the manufacture of wood or wood pellets. They serve to separate from
- Wood dusts and volatile organic compounds in pneumatic conveying and drying systems Wood dusts and volatile organic compounds in pneumatic conveying and drying systems.
- the invention has for its object to provide a device for separating foreign particles from a gas stream, which is simpler in construction and cheaper to manufacture, which has a higher selectivity and a generally improved efficiency. Furthermore, a procedure should be created.
- the object of the device for separating foreign particles from a gas stream comprises the following features:
- Injection nozzle for injecting liquid into the pipeline
- guide vanes which are arranged on the displacement body or in the region of the displacement body to the soffit of the pipe;
- the pipeline has downstream of the displacement body means for removing foreign particles from the peripheral region of their
- the power increase and the small installation space is achieved by the combination of the above features.
- Components are absorbed on the surface of the drops.
- the washing performance correlates with the specific surface of the droplets and is thus the
- Diameter of the drops inversely proportional.
- the laden after washing laundry liquid drops are due to their inertia by the integrated axial DC swirl deposition in the downstream
- the basic idea is essentially to be able to perform all the necessary functions for the efficient separation of foreign particles from a gas stream in a single apparatus.
- This device is characterized by low structural complexity and applicability in existing pipe systems.
- the device according to the invention can be arranged vertically or horizontally or inclined. Simultaneous acceleration and swirl generation in an annular gap improves the washing performance.
- the adjustable free flow area in the nozzle allows adjustment during operation.
- the device is suitable for the separation of
- Noxious gases for example VOC, HCl, SO 2 , Cl 2 , NH 3 , HBR.
- Acid mists for example HCl, H 2 S0 4 , H 3 P0 4 or oil mists.
- Fine dust particles for example metals, metal oxides, color pigments, fly ash, carbon black, wood, salts.
- a device thus combines the function of gas scrubbing by injection of liquid, in particular water, and their atomization and the subsequent swirl generation.
- the separation of the foreign particles proceeds according to the combined principle of a Venturi scrubber with a DC cyclone. It is preferably provided that the guide vanes are arranged between the inflow end and the outflow end of the displacement body.
- Displacement body be provided a dip tube, the inlet opening of the pipeline is concentrically enclosed and receives the gas stream;
- Immersion tube may be provided one or more branch lines; - Be the displacer axially displaceable;
- the displacement body rotationally fixed but axially displaceable.
- the pipeline can run vertically in the area of the displacement body and the displacement body can float freely in the gas flow without mechanical holding devices.
- the device is suitable for carrying out the method, but can also be operated independently.
- FIG. 1 shows a first embodiment of a device according to the invention.
- FIG. 2 shows a section of the object of FIG.
- FIG. 3 shows a schematic representation of an alternative solution of the invention
- the device according to the invention shown in FIG. 1 comprises a pipeline 1 with an inlet opening 2 for introducing the gas stream to be treated.
- the pipeline 1 has a venturi constriction 3.
- an injection device comprising a plurality of injection nozzles 4 for injecting liquid into the pipeline 1.
- it is preferably water.
- the pipeline 1 encloses a displacement body 5. This is arranged concentrically in the pipeline 1.
- the upstream end 12 of the displacement body 5 has the shape of a cone with directed against the flow tip.
- the outflow end 13 of the displacement body 5 also has the shape of a cone with in
- the displacement body 5 forms with the lateral surface of the pipe 1 a
- constriction 7 In an axial section downstream of the displacement body 5 is a constriction 7.
- the pipe 1 is abruptly reduced at this constriction to a smaller diameter. Accordingly, the pipeline 1 is less
- the end portion can also be designed as shown in Figure 3.
- the pipe 1 runs vertically. It protrudes a dip tube 9 into the pipe 1 in this case.
- the inlet opening 10 of the dip tube 9 is surrounded concentrically by pipeline 1.
- the branched partial flow 15 preferably consists of contaminated liquid.
- Displacement body 5 and wall of the pipe 1 further torn. This increases the specific surface area and increases the absorption capacity. In the annular gap of the free cross-section between the liquid on the one hand and disperse or gaseous contamination on the other hand is reduced. This will be the
- the vanes 6 are arranged in the illustrated embodiment, the displacement body 5. Instead, they can also be fixed to the soffit of the pipe 1.
- the subsequent deposition of the loaded washing liquid drops from the rotating air flow takes place on the principle of a DC cyclone. In this case, flow and outflow run without internal reversal of direction. See the figure 3.
- the displacement body 5 may, preferably with an adjusting device 16, be axially displaceable. Once set in a specific axial position, it is initially stationary. Thus, the flow cross section at the injection point of the water can be adjusted according to the requirements of the operation.
- the pipeline 1 extends vertically in the region of the displacement body 5.
- the displacement body does not necessarily have to be fixed, for example by mechanical connections to the fixed environment.
