Definitions
- the invention relates to a nozzle device in a dissolving apparatus for dissolving a solid in a solvent, preferably a powdery solid in water, according to the preamble of claim 1.
- the object of the invention is to shorten the dissolving time in a mixing tank compared to known dissolving devices of the generic type and to simplify the apparatus itself.
- the suspension is not supplied to the mixing tank via its jacket part, but rather via its bottom part.
- a nozzle device is provided which, starting from a feed pipe and viewed in the direction of flow, branches into an annular gap nozzle and a pipe nozzle.
- the annular gap nozzle generates an annular gap flow which is oriented essentially transversely to the longitudinal axis of the mixing tank.
- the remaining partial flow of the supplied suspension is discharged via a tubular nozzle, which generates a driving flow in the mixing tank, which, with respect to the longitudinal axis of the mixing tank, has an axial and additionally a tangential directional component oriented towards the head part.
- a convection flow is generated in the mixing tank via the tubular nozzle, which covers the entire tank content there and circulates it both in the vertical and in the tangential direction.
- the one about the ring The other partial flow of the suspension, which is discharged through the gap nozzle, crosses the preferably downward convection flow and, on the one hand, leads to intensive mixing of the suspension and, on the other hand, this very high-energy cross-flow favors the suspension conditions the convection flow and the annular gap flow inevitably the convection flow therefore includes the entire tank content as planned in the mixing and dissolving process, stagnant areas in the tank with less favorable mass transfer conditions are thereby reliably avoided
- annular gap nozzle it has proven to be advantageous to design the annular gap nozzle in such a way that it extends over an application angle of approximately 360 degrees, measured in a plane perpendicular to the longitudinal axis of the mixing tank. This measure enables and can discharge the annular gap flow over the entire cross-sectional area of the mixing tank thereby intersect with the convection flow flowing down over the entire circumference of the cylindrical jacket of the mixing tank.
- the proposed nozzle device is advantageously simplified if, as is also proposed, the feed pipe of the nozzle device is passed through an outlet housing serving to remove the suspension from the bottom part. In this case, only a single opening in the bottom part of the mixing tank is required
- the feed pipe is arranged coaxially to the longitudinal axis of the mixing tank in the base part, the arrangement is simplified on the one hand, on the other hand, the largely axially symmetrical characteristics of the flow pattern in the mixing tank result in particularly favorable dissolving and suspending conditions
- the dissolving and suspending conditions are further decisively improved if the solid to be suspended and dissolved is not fed directly to the mixing tank, but rather to the suspension pumped around in the circuit outside the mixing tank.
- a feed device for the solid into a between the Drain housing and a circulation pump provided suction line
- FIG. 1 shows a longitudinal section through a schematic illustration
- Figure 2 shows an enlarged view of a longitudinal section through that part of
- Nozzle device which is identified by the detail “X” in FIG. 1 and FIG. 2a shows a plan view of the nozzle device according to FIG. 2 REFERENCE SIGN LIST OF ABBREVIATIONS USED
- the opening apparatus ( Figure 1) consists essentially of a mixing tank 1, with a bottom part 1 a, a cylindrical jacket part 1 b and a head part 1 c, a housing 2 flanged to the bottom part 1 a, which consists of a drain housing 2 b and an inlet housing arranged underneath 2a, and a circuit line 6 starting from the outlet housing 2b and opening into the inlet housing 2a.
- the latter consists of a suction line 6a, which connects the outlet housing 2b to a circulation pump 5, and a pressure line 6b, which leads from the circulation pump 5 to the inlet housing 2a.
- a feed device 4 for a solid F opens into the suction line 6a.
- a nozzle device 3 penetrates the outlet housing 2b in order to engage in the bottom region of the mixing tank 1 via a bottom opening 1d in the bottom part 1a.
- the nozzle device 3 consists of a feed pipe 3a (see also FIG. 2), which is between one of the inlet channels - Home 2a and drain housing 2b arranged, not specified partition goes out and is limited at its other end by a cover 3b such that an annular gap nozzle 3c is formed between the end of the feed pipe 3a and the cover 3b.
- the cover 3b is at least one
- the connecting web 3e is connected to the feed pipe 3a, and it is also provided with a preferably centrally arranged, not designated opening, to which a pipe nozzle 3d is connected.
- the latter is designed in such a way that its opening facing away from the cover 3b has a direction that on the one hand to the head part 1 c of the mixing tank 1 oriented axial and z additionally has a tangential, ie a directional component oriented in the direction of the circumference of the mixing tank 1.
- a vertical setting angle ⁇ of the pipe nozzle 3d for generating the axial direction component is shown in FIG. 2, the tangential directional component results from a tangential setting angle ⁇ (FIG. 2a)
- the suspension and dissolution of the solid F in the solvent is as follows: First, the amount of solvent, usually water, required for the amount of solid F to be dissolved is introduced into the mixing tank 1. Then the water is fed from the bottom area via the circulation line 6 by means of the circulation pump 5 of the mixing tank 1 and the subsequent outlet housing 2b are suctioned off and then fed back to the mixing tank 1 via the inlet housing 2a and the feed pipe 3a following this on the way via the annular gap nozzle 3c and the pipe nozzle 3d
- Solid F is now continuously introduced into the suction line 6a via the feed device 4.
- This suspension of solid F and solvent passes through the circulation pump 5 and the pressure line 6b into the inlet housing 2a and from there on the way via the inlet pipe 3a to the annular gap nozzle 3c and on the other hand into the pipe nozzle 3d.
- a feed cross section A in the feed pipe 3a (FIG.
- the propellant flow T generates a convection flow K in the mixing tank 1, which is oriented upwards on the one hand and tangentially, on the other hand, ie in the direction of the circumference of the mixing tank 1 and which leads to a substantially downward flow in the region of the cylindrical jacket part 1b
- the bottom region of the mixing tank 1 is crossed by an annular gap flow R generated in the annular gap nozzle 3c.
- the proposed nozzle device (3) achieves a dissolving time of less than 5 minutes, for example, while comparable known dissolving apparatuses require a dissolving time of 15 to 20 minutes for the same amount of solid F.
