DESCRIPTION:

BRIEF SUMMARY
This invention relates to a mixer for absorbing gases and steam in liquids and the mixing thereof, as well as for mixing and homogenizing a liquid with another liquid and atomization of a liquid in a gas or steam.
A wide range of installations, which serve the above-noted purposes, can be found in the chemical industry, pharmaceutical industry, water and waste water purification technology, bioengineering, in technology for environmental protection, in fish-hatching and in heating and cooling engineering. Well-known amoung the known solutions are mixers with nozzles, mixing injectors, rotary cleaning brushes, rotating disks, vane-type blades, turbines and other special mixers in which one element not only serves the task of mixing but also the task of introducing gas into the liquid.
As examples of the devices which simultaneously solve the problem of mixing and gas supply, there may be mentioned Hungarian Patent No. 180,647, German Patent No. 2,513,917 and British Patent No. 2,164,576, which can be characterized by the fact that a direct electric drive is provided, the drive motor being located in the liquid space or above it and constructed in a precise manner. As well, they each provide a drive shaft inserted through the wall defining the liquid space, which is extremely expensive way of providing a drive shaft; moreover, when there is a higher liquid pressure, the gas supply requires separate gas pressure step-up means.
It is a well-known fact that, for a given liquid, an increase in the pressure of the liquid results in the capacity of the liquid to absorb gas increasing. For this reason, bubble forming systems, operated with gas pressure step-up means and compressors and provided with nozzles and mixing nozzles, have become widespread. With these systems, through mixing without dead space and absorption can be solved either on a large surface and with numerous nozzles or, with a smaller surface, the height must be greatly increased, and possibly an installation placed quite deep underground will be required. The last characterized solution is known from sewage technology, tower biology and from biological clarification with a deep shaft; these also represent extremely expensive items. Those installations which are currently considered to be up-to-date are quite well-known from the trade literature, as e.g. Wulf Crueger-Annelises Crueger: Biotechnologie (Verlag fur die Landwirtschaft, 1987).
It is an object of the present invention to eliminate the disadvantages of the known installations, i.e. to develop an installation with simultaneous effective mixing which would function with low investment and operating costs and which can be widely used.
Accordingly, the present invention provides a mixer for absorbing or mixing gases in liquids or for mixing a liquid with another liquid and/or for atomizing a liquid in a gas, said mixer comprising: an impeller having vanes which are bent backward and are surrounded by a front wall having an exhaust opening and a backplate, said backplate sealing off a conveying area; a sectional chamber in the shaft of said impeller, said sectional chamber comprising a hollow main shaft stub, at least two vanes and at least two pipes disposed about the axis of said shaft stub, said pipes being purposed to convey propellant, an end of each of said pipes adjoining said sectional chamber and an opposite end of each of said pipes having a primary nozzle, said impeller being sealed off with a casing through which injectors are disposed which are coaxial with said primary nozzles, mixing nozzles of said injectors being attached on three sides to said casing of said impeller, and to said front wall and to said back wall and connected via said vanes on the fourth side, said main shaft stub being attached to a stationary conduit for said propellant via a rotating connector.
The invention is based on the knowledge that by appropriately designing the impeller vanes of a ventilator, or pump with radial overflow and with aid of correspondingly disposed nozzles, a mixer can be created which
