Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for the continuous mixing of fluids formed by liners with screw surfaces. pipelines. The device is intended for dispersions of intermixable liquids, for gas dispersions into liquids, intensification of heat transfer during viscous liquids flow, creation of suitable interfacial area for heterogeneous reactions, better homogenization of components and the like.

The prior art devices for continuous mixing of fluids utilize various types of ellipsoidal pipeline internals. These include plates, various screw faces, oblique grilles, conical lamella bodies, components of composite longitudinal lamellas with embossed grooves that form oblique, intersecting channels and the like. The disadvantage of the slats is the high pressure drop and susceptibility to clogging, which is difficult to clean. The disadvantages of screw-shaped mixers are that they require a relatively large mixing length and, furthermore, that with a larger viscosity difference of the mixed liquids, the mixing efficiency decreases considerably. . In addition, these mixers exhibit a substantial reduction in the mixing efficiency in the transition hydrodynamic mode.

The drawbacks are eliminated by the continuous fluid mixing device according to the invention, consisting of inserts with screw faces inserted in the pipeline. The principle is that the insert consists of a prism shell β · Γ with three to six edges, each wall of which is helically twisted · The pitch of the helix is no more than 10 times the distance of the insert. The walls of the prism touch each other at the beginning of the liner and after a long distance touch the inner tents of the pipe. The length of the liner in the pipe is 0.5 to 10 times the internal diameter of the pipe.

The basic advantage of the device according to the invention is that. The process according to claim 1, which allows intensive mixing of viscous liquids, emulsification and dispersion of gases into the liquid.

The apparatus according to the invention is explained in more detail in the following. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION An axohometrioc view of a fluid mixing apparatus with a four-sided prism is shown in the extended state.

The device consists of a liner 2 located in the pipeline 1. The shape of the liner 2 is formed by the modification of the prism shell with four edges * The diameter of the circle described by the perpendicular cross-section of the prism is equal to the inner diameter of the pipeline X. 10 * 3 times the inner diameter of the pipe 11, preferably 1.1 to 1.5 times the inner diameter of the pipe, preferably 1.1 to 1.5 times. The tines 2 of the insert 2 forming the hollow prismatic body are separated from each other in the fixed edges almost over the entire distance of the edges. with the exception of the cross section at the beginning of the insert 2 · By rotating the free end of each wall 2 of the insert 2 in the same direction, the walls are collapsed into a helical surface. Pitch ěroubovica sagging of the wall 2 is at most 10 times the distance of the insert 2 ^«8 preferably four times the distance of the insert 2 * Combining answer ICI CHSi edges of each wall 2 ^{at the} end of the insert 2 to a longitudinal axis of the insert node 2 ,, which extend radially outwards from the wall warping 2 The width of the uniform walls 2 of the liner 2 4 ® P ° is remotely modified on both sides or one side so that the liner 2 should have a coaxial cylindrical surface with a diameter corresponding to the diameter of the pipe JL.

When shifting the liners 2 in succession, it is possible to alternate the liners 2 with the opposite helical bush either individually or in groups, in such a way that the beams of the walls 2 coming out of the knot on the longitudinal axis of the liner 2 are directed to of the peripheral edges of the end cross-section, the inserts 4 can be pushed together. the relative position is fixed. The left and right-hand helix is equalized by the torque exerted by the flowing fluid on the adjustment.

The device according to the invention operates in the following manner:

At the end of the insert 4, the liquid or mixture flowing through the pipe 8 is divided by a node into streams whose number corresponds to the number of prism walls. The fluid flowing into the liner is fluidized. through the gaps between the helical warped walls 4 of the liner 4, and parts of the liquid flowing between the liner 8 and the wall of the pipe 6 are mixed. Upon entering the next insert £, the stream splitting occurs again ^.

The bleaching of the inlet currents and the mutual passage of the currents during the flow through the one element 8 leads to intensive mixing, e.g. ;

fc '.

The device according to the invention can be used in particular for mixing viscous liquids, emulsions, gas dispersions into liquids, for intensifying heat transfer and the like.
