Embodiment Construction

[0020] The device 1 has a mixing tube 2 with a straight section 3 and a curved section 4 adjoining the straight section in flow direction and ending at an outlet 5 . The outlet 5 is surrounded by a flange 6 by means of which, for example, the outlet 5 can adjoin the opening of the container.

[0021] Opening at the upstream end of the mixing tube 2 is an arc-shaped air inlet section 7 , which has an air inlet 8 at its free end which is surrounded by a flange 9 . The flange 9 is associated with a counter-flange 10 . The two flanges 9, 10 can be screwed to each other. The air inlet section 7 and the mixing tube 2 with the straight section 3 and the curved section 4 form the main pipe 11 of the device 1 .

[0022] A straight inlet line 12 protrudes into the upstream end of the mixing tube 2 , in the straight section 3 of the mixing tube 2 , downstream of the opening of the air inlet section 7 into the mixing tube 2 , Ends on access port 13. The mixing tube 2 and the inlet tub...

Abstract

The invention relates to a method for gassing liquids, particularly for aerating water, gas being fed to a mixing tube (2) via a gas inlet (7), and liquid being fed via a liquid inlet (13) to form a mixture of gas and liquid, characterized in that the liquid is centrally introduced into the mixing tube (2) via a feed pipe (12) and the mouth opening (13) thereof, and is spread in the region of the mouth opening (13) by means of an impact onto a spreader (18).

Description

technical field [0001] The present invention relates to a method of aerating a liquid, in particular water, in which method gas is delivered to a mixing tube via a gas inlet and liquid via a liquid inlet to form a mixture of gas and liquid. Furthermore, the invention relates to a device for carrying out the method. Background technique [0002] For various purposes it is necessary to entrain the liquid or to enrich it with gas. It is particularly common to aerate water, especially bodies of water, in order to increase the oxygen content of the water and thereby improve the living conditions for plants and / or fish or to prevent the body of water from becoming stagnant. [0003] For the aerobic treatment of sludge, a method is known from CH 642563 A5 in which the sludge is introduced into the mixing tube via a curved pipe connection and via a conical valve. The cone valve has a valve body which is guided displaceably between a closed position and a downstream open position. ...
