ABSTRACT OF THE DISCLOSURE

   A physicochemical loop reactor comprises two loop channels and means for inducing a circulation of processed reactants through and around said channels. The letter are symmetrically biased at a sharp angle in relation to their common inlet, which is directed to the vertex of said angle and connected to the reactor. The channels are adjacent to each other at said vertex where their outlets oppose each other, cross the reactor inlet and are connected to the reactor outlet.

BACKGROUND OF THE INVENTION

   The invention pertains to physicochemical loop-type reactors with the reactants circulating via loop channels, a pump, propulsion jet and the like inducing the circulation. The main function of such known reactors (see US patent No. 4,037,825 and the reference cited in) is mixing of liquids and gases.
   The objective of the present invention is enhancing the known uses and widening greatly the reactors possibilities by achieving heterogeneous and homogenous effects in fluids for emulsification, dispersion, enhancing chemical reactions, wastewater treatment, degassing, aerosol production, coagulation, etc.

SUMMARY OF THE INVENTION

   The above stated objective is attained by means of creation of (ultra)sonic oscillations of reactants in the reactor. For this, the loop channels are symmetrically biased at a sharp angle in relation to their common inlet. The latter is directed to the vertex of said angle and connected to the reactor inlet, the channels being adjacent to each other at said vertex wherein their outlets oppose each other, cross the reactor inlet and are connected to the reactor outlet.
   The invention will be more readily comprehended from the following description, drawings and appended claim.

BRIEF DESCRIPTION OF THE DRAWINGS

   Fig. 1 is a design of the first embodiment of the loop reactor with machined the loop channels;
   Fig. 2 is a design of the second embodiment with tubular loop channels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

   The reactor is provided with loop channels 1 and 2, machined in a body 3 (Fig. 1), or tubular (Fig. 2). The channels are symmetrically biased at a sharp angle in relation to their common inlet directed to the said angle vertex 4 and connected to a reactor inlet 5. The channels 1 and 2 are adjacent to each other at said vertex. Therein their outlets 6 and 7 oppose each other, cross the inlet 5 and are connected to a reactor outlet 8. The body 3 (Fig. 1) is provided with a cover 9 and packing 10, all of them being fixed together with screws 11.
   The substances (gas, liquid, aerosol, emulsion, dispersion, etc.) enter the reactor through the inlet 5. Two or more reactants can be previously mixed by known methods (e.g. in counter flow, pumps, etc.), or several pipes 15 and 16 for reactants can be connected to the inlet 5 as it is shown in Fig. 2.
   The work of the reactor is based on the Coanda effect described for example in US patent No. 2,052,869, although one pouring water out of a pot can observe the effect oneself. The jet sticks to the wall of the pot and does not go into the cup.
   Let an occasional influence deflect the jet from the inlet 5 to the right. The surrounding medium flows carried away by the jet on its each side are approximately equal, but the effective area through which the medium is carried away is decreased on the right and increased on the left. This causes the force directed into the same side in which the jet has been initially deflected. As a result, the jet is deflected farther to the right side and sticks to the right wall.
   Then the flow in the right channel 2 returns back via the outlet 7 to the initial jet and deflects the latter into the left channel 1. Next, the flow follows the left channel 1, returns back via the outlet 6 to the initial jet, deflects the latter into the right channel 2, and the process is repeated, (ultra)sonic oscillations being produced. The treated fluid goes out through the outlet 8.
   The analytical description of the process in the jet sticking to a wall is very difficult, and the most common method of such investigations is experimental.
   Heterogeneous and homogenous effects of (ultra)sonic in all systems (liquid-liquid, gas-liquid, liquid-solids and gas-solids), obtained herein are well known and do not require further explanation. These effects provide the possibility to treat emulsion, dispersion, wastewater, aerosol, and the like, to enhance chemical reactions, degassing, coagulation, etc.

   What is claimed is:

   1. A physicochemical loop reactor, comprising two loop channels and means for circulating processed reactants through and around said channels biased symmetrically at a sharp angle in relation to their common inlet, which is directed to the vertex of said angle and connected to the inlet of the reactor, the channels being adjacent to each other at said vertex where their outlets oppose each other, cross the reactor inlet and are connected to the outlet of the latter.
