Abstract

The utility model relates to the field of hydrodynamic mixing. A device for mixing components in oncoming flows is proposed, comprising a mixing chamber with two opposed coaxial channels for supplying the mixed components towards each other, in which, before entering the mixing chamber, partitions with through holes and an exhaust channel are installed, wherein said through holes are made in the form confuser nozzles, mirror-symmetrically located in opposite partitions of the supply channels. The utility model provides an increase in the efficiency of mixing components in oncoming flows.

Description

The technical field to which the utility model relates.

The utility model relates to the field of hydrodynamic mixing and is aimed at increasing the efficiency of devices for mixing, mainly, liquid components in counter flows - jets.

State of the art

The prior art [copyright sv-in SU 296549 A1, publ. 11/02/2018; Patent RU 2016641 C1, publ. 07/30/1994] a device for mixing components in oncoming flows is known, comprising a mixing chamber with two opposed coaxial channels for supplying the components to be mixed towards each other and an exhaust channel.

The main disadvantage of the known devices is the low efficiency of mixing the oncoming flows in the mixing zone.

Also from the prior art [patent RU 188163 U1, publ. 04/01/2019] there is known a device for mixing components in oncoming flows, comprising a mixing chamber with two opposed coaxial channels for supplying the mixed components towards each other and an exhaust channel, while inserts - partitions with through holes are installed in the supply channels before exiting to the mixing chamber. This technical solution is selected as the closest analogue (prototype).

The disadvantage of this design is the relatively low speed of the outflow of components from the through holes of the inserts - partitions of the supply channels, which limits the intensity of interaction of oncoming flows in the mixing zone.

Utility Model Disclosure

The proposed utility model is aimed at solving the technical problem of eliminating the disadvantages of known devices, including the prototype.

The technical result achieved in this case is to increase the efficiency of mixing the components in the oncoming flows.

The solution of this problem with the achievement of the claimed technical result is ensured by the fact that in the device for mixing the components in the oncoming flows, containing a mixing chamber with two opposed coaxial channels for supplying the mixed components towards each other, in which baffles with through holes are installed before going into the mixing chamber, and the tap channel, according to the utility model, the through holes are made in the form of confuser nozzles, mirror-symmetrically located in the counter zhnyh septa inlet channels.

The proposed presence of confuser nozzles, mirror-symmetrically located in opposite partitions of the supply channels, increases the flow rate of the mixed components, which provides a high degree of turbulization of the oncoming flows - jets in the mixing chamber, and accordingly, increasing the efficiency of the claimed device.

Brief Description of the Drawing

The drawing shows a General view of a device for mixing components in oncoming streams.

Utility Model Implementation

A device for mixing components in oncoming flows comprises a mixing chamber 1 with two opposed coaxial channels for supplying 2 and 3 of the mixed components towards each other and a channel for tapping 4, while baffles 5 and 6 are installed in the supply channels 2 and 3 before exiting into the mixing chamber 1 in which confuser nozzles 7 and 8 are made, mirror-symmetrically located in opposite partitions 5 and 6 of the supply channels 2 and 3, respectively, with each confuser nozzle 7 in the partition 5 corresponding to a confuser nozzle a plane 8 in a partition 6 located on the same longitudinal axis — a straight line perpendicular to the plane of symmetry on which the confuser nozzle 7 is located.

The claimed device for mixing components in oncoming streams works as follows.

Mixed, preferably, liquid components are fed through opposed coaxial supply channels 2 and 3 towards each other. When the mixed components flow out of the confuser nozzles 7 and 8, which are mirror-symmetrically located in the opposite partitions 5 and 6 of the supply channels 2 and 3, towards each other, acceleration and division of the oncoming flows into numerous jets and their intensive turbulization during collision, which leads to effective homonization, input components in the mixing chamber 1. The formed homogeneous mixture is withdrawn from the mixing chamber 1 along the exhaust channel 4.
