CZ306747B6 - A device for the maintenance of containers with a siliphos polyphosphate filling - Google Patents

Abstract

The invention relates to the device for the maintenance of containers (1) with the siliphos polyphosphate filling (2) for treating water in order to prevent limescale formation, which are provided with the inlet (3) of cold water, leading to the bottom of the container and the outlet (4) of the treated water. The device is formed by at least one tube (5) connectable to the cold water inlet (3) which is, at its end located above the filling (2), provided with at least one nozzle (6).

Description

Technical field

The invention relates to a device for the maintenance of containers filled with siliphos polyphosphate for the treatment of water to prevent the formation of scale, which are provided with a cold water inlet opening at the bottom of the container and draining the treated water.

BACKGROUND OF THE INVENTION

Containers containing siliphos polyphosphate filling are used in water treatment plants, boiler rooms and the like to treat water to prevent scale formation. These are usually cylindrical vessels with a vertically positioned axis, which are provided with a cold inlet at the top, which is led to the bottom of the vessel. The container is filled up to a certain height with a granular polyphosphate charge which gradually dissolves. Water flows around these granules and is discharged through the discharge of treated water.

A disadvantage of the existing solutions of the existing equipment is that the granules dissolve and form a rigid layer at the bottom of the container, which does not allow the water supply to be released and is constantly growing. It is not possible to remove it by conventional means and therefore it is necessary to replace the whole container after reaching a certain level of solid layer.

Existing solutions are unstable when installing the water supply. The water inlets are provided with spray nozzles made of poor quality material at the end, which causes the clarifier to be short-lived. These spray nozzles do not allow increased cleaning performance, so they still settle and do not clean the silofos charge. This leads to economic losses. The filling is not used for the overall water treatment and treatment, which results in the hardening of the siliphos and the malfunction of the cleaning vessel. Such a solution has high operating and maintenance costs. A significant disadvantage is the low lifetime of existing equipment. Another significant disadvantage is the high costs of ecological disposal of existing equipment. Existing equipment requires frequent inspection, which is difficult to operate, with the risk of injury.

SUMMARY OF THE INVENTION

Said drawbacks are overcome by a device for the maintenance of containers filled with siliphos polyphosphate for water treatment to prevent the formation of limescale, which are provided with a cold water inlet opening at the bottom of the container and a discharge of treated water according to the present invention. Its essence is that it consists of at least one tube connectable to the cold water inlet and is provided with at least one nozzle at its end located above the filling.

The nozzle is preferably provided with a rotating head and the tube may have an adjustable length.

The solution is characterized by simple and easy handling. The proposed solution will considerably prolong the durability of existing equipment, since it will allow the existing containers to be perfectly cleaned without the need to shut down and use unsuitable means. Since it is possible to extend the length of the nozzle tubes up to the length of the container, it is possible to clean the container to the bottom. The tubes can be provided with various nozzles, for example rotary nozzles, which clean with greater efficiency and in less time. The solution prevents siliphos from settling and thus increases the efficiency of water treatment. There is also the possibility of different variations in the location of the nozzles, with the possibility of a higher level of clarification. The whole solution is more environmentally friendly and allows to reduce the content of harmful substances in waste water. The proposed solution brings high cost savings compared to the original cleaning method. The new solution is easier to operate.

Clarification of the drawing

A maintenance device for siliphos polyphosphate water treatment containers for preventing scale formation, according to the present invention, will be described in more detail with reference to the accompanying drawing, in which: FIG. 1 shows a diagram of an exemplary device.

Examples of technical solutions

An exemplary device for maintaining containers 1 of siliphos polyphosphate for water treatment to prevent scale formation having a cold water inlet 3 opening at the bottom of the vessel and a treated water outlet 4 is formed by a tube 5 connectable to the cold water inlet 3, which is provided at its end located above the cartridge 2 with a nozzle 6. The tube 5 is either guided in different lengths or has an adjustable length.

In another embodiment, the nozzle 6 is provided with a rotating head.

If the siliphos layer is deposited, maintenance is connected to the cold water inlet 3 by a tube 5 which at its end located above the filling 2 is provided with a nozzle 6. The tube 5 is chosen so that the nozzle 6 is above the surface of the siliphos layer. The water emerging from the nozzle 6 gradually removes the solidified charge and drains it off. The length of the tube 5 can be varied until the bottom of the container 1 has been reached. After the solidified filling 2 has been removed, the container 1 is filled with new siliphos granules and the nozzle tube 5 is removed.

Industrial applicability

Device for maintenance of siliphos polyphosphate containers for water treatment to prevent the formation of scale, according to this technical solution it will find application especially in water treatment plants, boiler rooms.
