Case 2509

Wilhelm S c h u 1 e r Piltertechnik GmbH. 6719 Eisenberg / Pfalz, Tiefenthaler Strasse 16

Device for fine-bubble introduction of air or Gas in sewage or similar liquids.

The innovation relates to a device for introducing air or gas in fine bubbles into wastewater or similar liquids, especially for fine-bubble introduction or distribution. of air for contacting air oxygen with wastewater Activation process, or for aerated sand trap, consisting of a supply line for the air or gas and a or a plurality of distribution elements connected to them.

Ea are different versions of distribution elements for the coarse, medium and fine bubble aeration is known. These consist e.g. B. in drilled plastic pipes, open pipes with or without baffle plate, synthetic resin-bonded or sintered ceramic, sintered plastic pipes, drilled drilling with saran cord wrapping, filter plates, foam, etc.

In order to achieve the highest possible entry of Op in the wastewater to be aerated To achieve., the fine bubble ventilation is preferred. In the case of fine-bubble ventilation, less energy is required more oxygen introduced than with medium or coarse-bubble aeration. The disadvantage of the fine-bubble ventilation, Particularly when using ceramic and synthetic resin-bonded materials, there is a tendency towards clogging. In the case of Stromau, the water with the impurities penetrates into the pores of the ventilation material and sets them:, The aerators must then be removed and cleaned, ΐδ a is usually very complex. Very often this does not succeed so that the distribution elements have to be renewed.

Compared to this acquaintance, the innovation is that the distributor elements consist of a hollow body serving as a support frame, the walls of which are provided with openings and which is covered on the outside with a dense fabric covering the openings.

»Trained for the innovation« Switch to VÄT-twüungselensente the disadvantages of the known devices and still have the same apart from the particularly favorable oxygen input a number of other advantages. The simple construction must be pointed out in particular. In addition, these distribution elements have only a very low pressure loss. Also no clogging occurs due to failure of the entry air. Palis, however, should the distribution material be laid from the inside due to contamination from the air supply line, so can the fabric cover of the distribution elements can be easily peeled off and washed like other fabrics or textiles, to be ready for use again.

Tightly woven textiles made of cotton, wool, synthetic fibers, etc. can serve as reference material for the distribution elements.

The support frame of the device, as a carrier of the reference material, can consist of metal and / or plastic.

The support frame can advantageously be a tube provided with bores or slots.

The support frame can also be made from an extruded tubular space consist, or be composed of webs.

Another advantageous method of manufacturing the support frame can consist in that an etreckmetallartig formed Plate is formed into a tube

In the formation of tubular support devices, it is advantageous that this covering fabric as one at one end closed piece of hose. to train.

Of course, the support frame can also be a different than have a tubular shape, e.g. being·

The innovation is in an example in the drawing in the Iftngseehnitt shown.

Ih the connection piece 1, to which the fumigant, for example air, is fed via a line 2, the tubular support structure 3, which is closed at its free end, is fastened, eB by screwing in. In the wall of the support framework 3 , the openings 4, for. B. holes arranged. The tube piece 5, which is closed at one end, is drawn from a fabric over the support structure 3. The open end of the hose section 5 is attached to the connector 1. For this purpose, the coupling piece 1 is provided with a hanging groove 6 and the end part of the hose piece 5 is fixed in the annular groove 6 by means of a clamping ring 7 or by being tied into it
