Definitions
- the invention relates to a device for cleaning pressurized water in water supply, in particular domestic water supply installations, wherein a dirt filter is switched on in a water supply line, which has a mechanical filter element through which water flows and which is enclosed in a filter housing on the inflow side, the filter housing connecting to one in one
- the first sewage rinsing line opening into the sewer is connected and a pressure vessel is connected downstream of the dirt filter in the course of the water supply line, the water inlet being through an inlet opening and the water outlet being through an outlet opening.
- a device with these features is known from DE-A-37 38 231.
- the water flow supplied to the filter from the water supply line is divided into a waste water flow enriched with substances to be filtered out and a pure water flow depleted with these substances.
- the pure water flow is continuously fed to a storage element designed as a pressure vessel, which, at maximum fill level and maximum pressure, emits pure water to the extent via a waste water line secured by a pressure relief valve, as pure water is supplied from the filter.
- This constant water exchange prevents the water from becoming contaminated if the filter performance is sufficient to provide a sufficiently large flow of pure water and is not impaired by filter contamination.
- the dirt filter In conventional devices of this type, the dirt filter, usually a commercially available visual dirt filter, must be cleaned at regular intervals, otherwise too much dirt is deposited on the filter element, so that the filter performance drops as a result of the correspondingly increasing flow resistance or the pressure difference occurring on the filter element becomes so large that dirt is pressed through the filter element and gets into the installation.
- the cleaning of the dirt filter is cumbersome and complex, since the dirt filter has to be opened and the water supply line on both sides of the dirt filter has to be shut off. Regular cleaning of the dirt filter is therefore often or even regularly neglected, especially in domestic water supply installations, so that the dirt filter loses its effectiveness. Otherwise it is one Dirt filter only effective against water contamination from solids above a filter-specific particle size. Fine-grained contaminants pass through the filter element and are not excreted, just as little as gases contained in the water, such as carbon dioxide, air, etc.
- a device for cleaning pressurized water in water supply, in particular domestic water supply installations is known, a dirt filter having a mechanical filter element through which water flows and which is enclosed in a filter housing on the flow side, is switched into a water supply line, and a pressure vessel is connected downstream of the dirt filter in the course of the water supply line.
- the dirt filter is connected in series with several other, in particular chemical filters and a disinfection system, with the dirt filter at the beginning and the pressure vessel at the end of this filter chain.
- the filters and especially the dirt filter have replaceable filter elements.
- the water flow rates through the filters are measured and added up, which serves as a measure of the filter load and serves to acoustically and / or optically prompt the consumer to change the filter at the appropriate time.
- the water throughput is prevented by the filter, for which purpose valves are additionally provided in the water supply line. Therefore, the dirt filter also requires maintenance and replacement of the filter element at regular intervals.
- the pressure vessel serves as a drinking water collector and as a water temperature controller, one ensures the desired drinking water temperature of 10 to 20 ° C. There is also no possibility of separating gases contained in the water.
- GB-A-2 223 689 discloses a gravitational filter which is only under atmospheric pressure and which serves as a dirt filter for naturally flowing spring water.
- a flat mechanical filter element is inserted vertically, which divides the interior of the housing into an inlet chamber and an outlet chamber and the water flows transversely from the inlet to the outlet chamber.
- the inlet chamber can be washed out through an outlet line provided in the bottom of the filter housing.
- a sedimentation container for water and wastewater treatment which uses centrifugal forces in addition to gravity to separate suspended matter.
- the container which is flowed through a guide tube into an outer sedimentation zone flowing from top to bottom and into an inner sedimentation zone lying inside and inside, has upward flow zone inclined plate separators. Above these inclined plate separators there is an overflow channel for the clear water, the height-adjustable weir edge of which determines the water level in the tank above the top of the inclined plate separators.
- the inflow opening is located under the outflow opening, which connects directly to the overflow channel and is connected to the air space in the tank above the water level.
- the tank has a cone bottom with a central sludge discharge.
- the invention has for its object to provide a device of the type mentioned in such a way that filter cleaning is possible in a simple manner and a separation of fine-grained solid and gaseous impurities is achieved.
- the filter housing is connected below the filter element via a first controllable shut-off valve to the first wastewater flushing line, that the inflow opening is arranged in the upper part of the container and the outflow opening in the lower part of the container, and that the pressure vessel is connected to one above the inflow opening Gas outlet line with a precision vent valve arranged therein as well as below the outflow opening is connected to a flushing line which is connected via a second controllable shut-off valve to a second sewage flushing line also opening into the sewer.
- the shut-off valve on the filter housing is opened, the coarse dirt caught on the filter element is rinsed off the filter element and washed into the sewer through the waste water flushing line.
- the regular cleaning of the dirt filter can therefore only be done by regularly opening the shut-off valve without the need to close the water supply line on the filter. If the shut-off valve is controlled automatically, the filter cleaning takes place regularly and without any personal effort. However, substances that still pass through the filter element are separated in the pressure vessel.
- the water flow in the pressure vessel is extremely low, so that in the water that has come to rest, all solid contaminants still entering the pressure vessel can sink to the bottom of the vessel, from where they also enter the sewer through the flushing line when the shut-off valve arranged therein is opened be flushed out, which can also take place regularly and without personal effort with automatic control of this shut-off valve.
- the gaseous impurities rise in the pressure vessel into the gas outlet line and are blown off by the precision vent valve. The water that has been cleaned of solids and gases in this way flows out of the pressure vessel into the house installation.
- a preferred embodiment of the invention is characterized in that a control filter is switched on in the part of the water supply line following the pressure container, which has a filter element through which the water flows and which is enclosed in a filter housing on the inflow side and accessible from the outside, the filter housing is connected below the filter element via a third controllable shut-off valve to a third wastewater flushing line that opens into the water channel.
- this control filter merely serves to check the effectiveness of the device according to the invention, the filter element here also being able to be subjected to an automatic cleaning process in order to ensure its effectiveness at all times. As long as no recognizable soiling settles on the filter element, the filter device works in the desired manner.
- the control filter is expediently equipped with a precision ventilation valve, which also allows control with regard to the degassing effect.
- gas outlet line be positioned at the highest and the purge line at the lowest point of the pressure vessel in order to exclude gas bubbles on the one hand and dirt accumulations in the pressure vessel on the other.
- Backflows can be prevented in the device in a customary manner in that in the water supply line a KFR valve is arranged upstream of the inflow opening of the pressure vessel or downstream of its outflow opening, namely in the flow direction of the water after that upstream of the inflow opening. in front of the filter downstream of the outflow opening.
