Description

Plate atomizers for liquids, especially for sulfuric acid The invention relates to a plate atomizer for liquids, in particular for Sulfuric acid. It is well known that disc atomizers have the advantage of producing sulfuric acid, that when passing the cold sulfuric acid through the chamber ceiling and when Atomizing into the chamber cools this down and thereby improves the performance of the chamber system is increased. However, it is difficult to get one with the fast rotating plate to achieve gas-tight seal between the chamber ceiling and the atomizer.

The aim of the invention is to secure this gas-tight seal.

For this purpose, the atomization chamber against the outside air is means a multiple liquid seal, e.g. B. sulfuric acid, sealed gas-tight. The multiple liquid seal is formed in that the plate shaft from is enclosed in a jacket pipe. At the upper end, the jacket tube forms with the usual 'so-called cup to which it is attached, in cooperation with the covering bell for the incoming atomized material a closure by overflow. At the lower end, the closure for the exiting atomization material is made by immersion of the jacket tube formed in a cavity in the plate.

The bell covering the overflow can, for example, consist of a fixed jacket pipe exist that against the shaft in a known manner a layer of glass wool or asbestos soaked in liquid is sealed. To the Securing the lower liquid seal and for regulating the atomization effect is the upper edge of the plate containing the cavity of the plate of a stationary one Surrounding baffle ring.

The figure shows an elevation of the plate atomizer, partially on average.

The vertical shaft a carries the centrifugal plate b with a cavity on the upper edge. The lower part of the shaft a and the centrifugal plate b are coated with lead as usual. The shaft a is mounted in ball bearings d and e which are attached to carriers. The drive pulley f is located between the bearings. The acid seal h, which surrounds the solid baffle ring o, sits on the ceiling of the sulfuric acid chamber. The baffle ring o is covered by the cover g. The cup i, into which the sulfuric acid is introduced through inlet l, sits on the lid g. The shaft a is surrounded by the stationary bell m, za. Between the cavity of the plate b and the bell m, n is the jacket tube k, which forms the overflow for the material to be fed at the top and is immersed in the liquid located in the plate cavity at the bottom.

The procedure is as follows: The plate b is set in rapid rotation and sulfuric acid is fed through the inlet L of the cup i. As soon as the liquid has reached the normal height in the cup i, it runs over the upper end of the jacket tube h into the cavity of the plate b, is thrown against the baffle ring o and atomized, which at the same time secures the lower liquid seal and regulates the effect of the atomization will.

The arrangement described allows relatively wide fluid paths, so that the risk of clogging in the lines by impurities is practical is excluded, but at the same time the safety of the gas seal preserved.
