Fig. 2 shows a section in the direction AA through the , the annular gap washer exclude the aui- ucgniMuiu naji Ti ₆ . 1. the cleaner would give mg of the annular gap washer shown in the figures passed through it dust-laden gases, while commissioning is used to purify dust-laden gases and decommissioning of the systems in addition to 20 installed in a corresponding pipeline 1 and the annular gap washer in front of and or behind these consists in its basic structure of one Shut-off elements in the form of slides or the like. Flow channel 2 and 2 drawn in like a venturi nozzle are seen. a fitted, adjustable in the axial direction The invention is now based on the object of the installation body 3. The installation body 3 is attached to a spin Annular gap washer of the type described above is connected to 35 del 4, which is led to the outside and to design that so equipped systems are operated via a servomotor, not shown subjects are as such plants that can be known with. This allows the installation body 3 in Annular gap washing ι are equipped. Raised and lowered in the direction of arrow 5. The annular gap washer according to the invention, in which this brings the possibility of this object is achieved in a known manner, is characterized in that the annular gap between the indentation of the built-in body with its circumference to the per 3 and the flow channel 2 and thus a B. Wall of the flow channel to its conclusion influencing the washing effect,
can be placed and that on the built-in body or on the according to the invention, the built-in body 3 is provided with the wall of the flow channel in a per se known circumference on the wall of the flow-way sealing elements. If it concerns 35 channel 2 to close it and it is an annular gap washer in the execution on the built-in body 3 or on ^ c ^- wall of the Ströform with in the flow direction in front of the built-in body ventilation channel 2 in a known manner not arranged on it, so is provided sealing elements, z. B. seat rings or the like, preferably the space above the built-in body provided. in the closed position designed as a water cup and 40 In the exemplary embodiment, the flow channel 2 provided with a level closure. conically drawn in and the installation body 3 The advantage achieved by the invention is appropriately conical. Summarized before installation darir to see that in plants, the body 3 is a Waschwasserzerstäubungsmit the annular gap washer according to the invention nozzle 6, with which the washing water in a known manner be equipped, atomized on additional shut-off elements in 45 conical shape, as the lines 9 on the shape of slides or the like. can be dispensed with, interpret. since the annular gap washer according to the invention on the one hand, the rest of the space above the built-in dic function of a conventional annular gap washer, body in the drawn closed position as on the other hand the function of a shut-off device over water cup? trained and with a level n'mmt. As a result, systems are provided with the inventive termination 8 which is led to the outside.
are equipped with the appropriate annular gap washer,
simpler than systems that use known ring gap washers are provided. Patent claims: So far it was assumed that the in
known annular gap washers provided built-in 55 body to accommodate the hydrodynamic 1st annular gap washer for cleaning Pressure are suitable, but not for the absorption of dust-laden gases, consisting of venturi the hydrostatic pressure are designed nozzle-like retracted flow channel and be able. In addition, the known shut-offs were fitted and adjustable in the axial direction organs of the closure body with the »Strömlings- 60 built-in body, characterized channel «only in the area of a seat ring in contact that the installation body (3) with its circumference comes, practically a nearly linear sealing the wall of the flow channel (2) to it development is realized, while with a ring closure can be placed and that on the mounting body Gap washcr the one-pipe (3) adapted to the flow channel or on the wall of the flow structure with the flow channel first a 65 channel (2) in a known manner sealing experiences pronounced surface contact. Known elements are provided. but can be borrowed with a real planar Bc- 2. annular gap washer according to claim 1, in the can hardly achieve an effective seal. Embodiment with in front of the flow direction I 671 387 the built-in body of a disordered water atomizing nozzle, characterized in that the space above the built-in body (3) in the closed position is designed as a water cup Cf) and is provided with a level seal (8) for this purpose. 1 sheet of drawings
