Reactor and method for decalcifying water and simultaneous removal of pollutants

Abstract

The invention relates to a reactor and to a method for decalcifying water and simultaneously removing pollutants, in addition to reducing the turbidity and disinfection which enables the largest possible variation in relation to carrying out the method and the amount of water which is to be treated. The reactor is characterised in that the fixed plates respectively comprise a bore in their centrethrough which a device for opening and closing the bores by means of conical and / or cylindrical-shaped closing elements extends. The upper ends of the device do not comprise plates and / or is connected to one or more non-fixed plate(s) and comprises a holding device. One or more of the fixed plates comprise peripheral openings in the edge area and the one or more additional fixed plate(s) do not have peripheral openings. The direct heating devices and aeration pipes are arranged in sections of the reactor at a distance from each other. The water inlet and the outlet are arranged in the upper and lower area of the reactor. One plate provided with only one large bore in the centre is placed over a plate comprising small holes on the edge. The inventive reactor can also comprise a discharge tap for removing residues.

Description

technical field [0001] The invention relates to a reactor and a method for removing calcium from water with simultaneous removal of pollutants, removal of turbidity and disinfection, according to the general concept of claim 1, the treatment process is carried out in a reactor with inlet and outlet, No chemicals are added and no filters are required. Background technique [0002] Such a reactor and method, the basic principles of which have been disclosed in the German invention patent DE 10247686. [0003] In addition, calcium hydroxide coagulation technology, equipment for inducing calcium carbonate formation and ion exchange technology are widely used in water decalcification. But these methods are all chemical treatments. There are also physical treatment methods, such as the decalcification method of changing the crystal structure in a magnetic field, the method of using cavitation, reverse osmosis, and membrane filtration disclosed in German invention patent DE 43 36...

AI Technical Summary

Problems solved by technology

For the production process, sometimes deoxygenation may be good for some production water, but it is not a good thing for drinking health

In addition, because the equipment is relatively complex, it is more suitable for large-scale water treatment in industry, but it is not suitable for situations similar to household use.

[0007] Although the patent DE 10247689 overcomes some of the shortcomings of the above-mentioned U.S. patents, it still has limitations in processing efficiency, because the strong micro-mixing of water actually only exists under the first plate that is closer to the heat source, and only exists on other plates. Occurs near the reactor wall

Therefore, it takes longer to process

In addition, because the plate is not fixed on the inner wall of the reactor and can be taken out of the reactor, it is impossible to achieve additional heating and aeration of the plate and the inside of the reactor

In addition, because the plate is fixed on the cover by one or two shafts, the discontinuous working device needs to take the cover and the plate out of the reactor by hand when adding water, so, especially for large reactors and It is inconvenient for hot water

[0008] For ion exchange, activated carbon, filtration and similar technologies, on the one hand, electricity is absolutely necessary, and on the other hand, they are very sensitive to turbidity and quickly become clogged
