An oxidizing device or the like

The present invention relates to an oxidizing device or the like for at least oxidizing a flowing liquid, such as water, comprising a body for attaching to a fluid flow having an air passage substantially passing therethrough. Preferably, the air flow sucked from the air conduit through the air conduit, preferably on an ejector principle, is provided through an orifice at the end thereof to the fluid flow for at least its oxidation. Preferably, the housing further comprises means for preventing flow through the air channel in the opposite direction, such as a non-return valve or the like.

It is known to operate a relatively simple oxidizing device of the type described above, for example, in connection with a threaded sleeve 20 for connection to a water pipe. In this case, a nozzle arrangement is provided inside the threaded sleeves to provide an ejector. . effect of air suction on water stream; - by means of a -: oxidizer attached to the threaded couplings, for example by means of a threaded connection. In conventional applications, the airflow '' in the oxidizing device is led to pass through a centrally extending passage therein to an orifice at its end surface, from which the airflow is further interfered with, for example, a lateral flow of water from the orifice.

In traditional models, the airflow is conducted from one of the • * »• orifices at the end of the oxidizer directly to the liquid flow. Because this type of solution »» »'l ... Clogging due to L 1 due to calcification and other reasons, it has been attempted to improve the efficiency of air distribution by, for example, small radial holes. In practice, solutions of this type have not worked for a longer period of time, but have continued to result in clogging of individual holes and ultimately total failure of the oxidizer. Thus, none of the current solutions has been able to solve the problem reliably 5 such that oxidation would occur under all conditions in a reliable and continuous manner with sufficient maintenance intervals.

The oxidation device or the like of the present invention is intended to provide a decisive improvement in the aforesaid and thus substantially increase the state of the art. To accomplish this purpose, the oxidation device according to the invention is essentially characterized in that a flow distribution arrangement for distributing airflow in the radial direction substantially at the end surface of the body is provided at least at the mouth of the body to prevent clogging of the mouth and / or air channel.

The solution of the present invention makes it possible, in a simple and reliable manner, to overcome the general problem described above, particularly with regard to ejector-based oxidation devices. The advantages of the oxidation device according to the invention can be mentioned: in addition to its simplicity and advantageousness in manufacturing, since the principles of the invention can be implemented quite advantageously by utilizing already existing oxidation devices, they are suitably machined.

In the following description, the invention will be illustrated in detail with reference to the accompanying drawings, in which: Fig. 1 illustrates a principle of the invention in conjunction with a preferred oxidation device, 104703 3 illustrates a side section of a preferred oxidation device of the invention; further illustrates the general principle of a preferred oxidation device according to the invention.

The invention relates to an oxidizing device or the like for at least oxidizing a flowing liquid, such as water, comprising a body 1 to be connected to a fluid flow having an air passage 2 substantially therethrough, through which air flow drawn from the air connection 3 is preferably ejector-like. w is substantially conducted through an orifice 4 at its end to conduct a fluid stream n for at least oxidizing it.

Further, the body 1 is preferably provided with means 5 for preventing flow 20 through the air channel 2 in the opposite direction, such as a non-return valve or the like. At least a blockage of the orifice 4 and / or the air channel 2 is provided in connection with the opening 4 of the body 1! to prevent it, a flow distribution arrangement 4a for dividing the air flow w in the radial direction substantially '' · 25 at the end surface p of the body 1.

1-3, as shown in Figures 1-3; 3 is intended to be used, for example, as shown in Figure 3 via a threaded connection 6, for further flow to the conduit: 30 for a screw connection 7, 8, such as a threaded sleeve 9 or the like, wherein the airflow w is arranged to pass through the body 1; μ through a central air channel 2 connected to the T ·· * · mouth 4 at its end surface p.

Y; In a further preferred embodiment of the principle of the invention, the flow distribution arrangement 4a comprises a distribution space 4a 'adjacent to the opening 4, the cross sectional Ai of the 104703 4 being arranged substantially larger than the cross section A of the air channel 2. With particular reference to Fig. 1, the flow distribution arrangement 4a, as shown therein, is formed by a recess arrangement 4a ", i.e. grooves, joining the air channel 2 at the center k of the body 1 at the end p of

As a further preferred embodiment, with particular reference to Fig. 10 2, the body 1 is preferably provided with a removable, such as threaded connection 9 or, respectively, means 10 for controlling the air flow w, such as a control valve, shut-off valve and / or the like. This allows either total shut-off of the air flow 15 or control thereof.

Referring further to Figure 2, an additional feed connection arrangement 11, such as a T-branch or the like, is provided in connection with the body 1 for doping chemicals or the like 20 in an air flow w and / or a liquid flow n.

. . It is to be understood that the invention is not limited to the foregoing; or the described applications, but can be very widely modified within the scope of the basic idea of the invention. In this case, it is of course obvious * '' that the oxidation device according to the invention can also be mounted, in deviation from the perpendicular position shown, to a degree of incline in connection with the liquid flow. Of course, the following is not taken into consideration: 30 positions per se on threaded sleeve arrangements, which, of course, can be implemented in many ways. It is, of course, obvious that the liquid stream can be sucked in by the apparatus of the invention in addition to or instead of: V: 35 gases. The drawings according to the invention are merely exemplary embodiments of the principle of the invention, although the solutions 104703 5 disclosed therein are already advantageously applicable as such in the conventional context.
