Description

A group of utility models relates to the field of water treatment and can be used in natural water purification systems by filtration using granular loading - water clarification, iron removal and demanganization, sorption purification for drinking, industrial and agricultural water supply, as well as for wastewater treatment.

Known clarification and sorption filters containing a housing, distribution devices, granular loading, nozzles for input and output of working fluids and piping with hydraulic fittings for transferring the filter from the filtering mode to the regeneration mode of the filtering load and vice versa. / "Water treatment equipment and installations for thermal power plants and industrial energy." Industry Directory 43-97. M. TsNIITEI, 1998, pp. 7-10, pp. 13-14 /.

Modern installations and water treatment plants include from several units to dozens of filters (clarification, sorption). With a high content of pollutants in the purified water, to ensure the required degree of water purification, the filters are connected in series, to increase productivity - in parallel / Frog B.N., Levchenko A.P. Water treatment. M. Publishing House of Moscow State University, 1996, p. 278, 392 /. Moreover, for the convenience of operation and automation of the filters, including the regeneration of the filter load, they are combined into groups of 3 (2) -4 filters in each.

Closest to the technical essence of the proposed installation is a water purification filtering unit containing a group of pressure filters with a granular charge and piping for supplying (discharging) working flows and switching them when the filters are switched from the filtering mode to the filtering filter regeneration mode and vice versa, as well as pipelines source and wash water and collectors for supplying raw water for treatment, removal of purified water, supply and removal of washing water and removal of the first filtrate and an automatic control system laziness. The piping of each filter contains pipelines for supplying water for purification, drainage of purified water, supply of washing water to the filters, drainage of washing water and the first filtrate, on which shut-off valves (hydraulic shut-off devices) with a drive are installed. Collectors combine

corresponding piping piping filter groups. / Zhivilova L.M., Maksimov V.V. Automation of water treatment plants and control of the water-chemical regime of thermal power plants. Reference manual. - M .: Energoatomizdat, 1986, p. 57-63 /.

The disadvantage of this installation is that for the output of filters for regeneration (switching work flows), a large number of hydraulic shut-off valves with a drive (valves, gate valves or dampers) are required - according to the number of supplied and exhausted work flows, which complicates the installation of the installation and its automatic control system, as well as determines the high cost of installation.

The objective of the proposed technical solutions is to reduce the cost of the installation of water purification by filtration and simplify the system for its automatic control, installation and maintenance of the installation.

The problem is solved due to the fact that, according to the first embodiment, in a water purification installation by filtration, containing a group of pressure filters with granular loading and piping with pipelines for supplying water for purification, drainage of purified water, supply of washing water to filters with shutoff valves with a drive and a discharge of washing water and a first filtrate, a source water pipe, a wash water pipeline with shut-off valves with a drive, collectors for supplying water for purification, a drain for purified water and a wash water supply s, the collector for draining the wash water and the first filtrate and the automatic control system for pressure filters are made with upward filtering, the pipelines for supplying water for cleaning and the supply of wash water in the filters are combined, the collectors for the water supply for cleaning and the water for washing are combined, the pipelines for draining the purified water are provided non-return valves, and the source water pipeline and the collectors for the removal of purified water and the removal of washing water and the first filtrate are equipped with shut-off valves with a drive.

According to a second embodiment, in a filtration water treatment plant comprising a group of pressure filters with granular loading and piping with pipelines for supplying water for purification, removal of purified water, supply of washing water to filters with shut-off valves with a drive and removal of washing water and the first filtrate, pipelines of source and wash water, manifolds for supplying water for purification, drainage of purified water and supply of wash water, collector for drainage of wash water and first filtrate and system

automatic control, pressure filters are made with upward filtering, pipelines for supplying water for treatment and pipelines for discharging purified water are equipped with check valves, and the piping for the source water and collectors for discharging purified water and draining water and the first filtrate are equipped with shut-off valves with a drive.

A group of utility models is illustrated by drawings.

Figure 1 shows the technological scheme of the installation for water purification by filtration through a group of pressure filters with upward filtration and combined pipelines for supplying water for purification and supplying washing water to the filters and combined collectors for supplying water for purification and washing; figure 2 is the same with pipelines for supplying water for purification and supplying washing water to filters and collectors for supplying water for purification and supplying water for flushing, performed separately.

Installation of water purification by filtration (Figure 1) contains a group of three parallel installed identical pressure (closed) filters 1 (a, b, c) with an upward flow of water containing a heavy granular load (quartz or expanded clay sand, sorption filter material, etc. ) 2 (a, b, c), upper

3 (a, b, c) and lower 4 (a, b, c) switchgears and piping, including pipelines 5 (a, b, c) for supplying water for treatment, combined with pipelines for supplying washing water to filters with shutoff valves with drive 6 (a, b, c); pipelines 7 (a, b, c) of the outlet of purified water (filtrate) equipped with check valves 8 (a, b, c) and pipelines of the drain of washing water and the first filtrate 9 (a, b, c).

The collector of the water supply for cleaning 10, combined with the collector of the water supply for flushing, is connected to the pipelines for supplying the source water 11 and the flushing water 12, equipped with inlet (control) valves 13 and 15 and shutter valves with the actuator 14 and 16, respectively. Water supply pipelines for treatment 5 (a, b, c) are connected to collector 10, combined with pipelines for supplying washing water to filters ..

The pipelines for the removal of purified water (filtrate) 7 (a, b, c) are equipped with check valves 8 (a, b, c) and are connected to the collector for the removal of purified water 17, equipped with a valve with actuator 18, and the pipelines 9 (a, b, c ) drain water and the first filtrate are connected to the collector 19 drain

water and a first filtrate equipped with a gate valve 20.

The automatic control system (not shown in the drawing) contains a software device for transferring the installation from the filtering mode to the regeneration (washing) mode of the filter load and automatic control of all stages of regeneration.

Installation of water purification by filtration (Figure 1) works as follows. In the filtering mode, the purified source water, if necessary pretreated - aerated (during iron removal) or with the addition of reagents (during demanganization, discoloration, etc.) is fed to the filters 1 (a, b, c) through the source water pipe 11 with an inlet valve 13 and a valve with an actuator 14, a collector 10 and water supply pipelines for cleaning 5 (a, b, c), through the lower switchgear 4 (a, b, c), pass through upstream filtration through a granular load 2 (a, b, c ), divert through the upper switchgear 3 (a, b, c) through purified water discharge pipes 7 (a, b, c) with non-return valves 8 (a, b, c) to the purified water collector 17 and fed to the consumer through a valve with actuator 18 (diverted to a purified tank water). All other valves with the actuator are closed.

The installation is transferred to the regeneration mode using remote or automatic control according to a given program.

To put the unit into the regeneration mode of the filter load, close the valve with actuator 14 on the source water pipe 11 and the valve with actuator 18 on the treated water discharge manifold 17. The first stage of regeneration — the loosening washing is carried out sequentially on each filter: the washing water is supplied through the washing water pipeline 12 through the valve 15 and the valve with the actuator 16 (open for the period of loosening flushing), opening the valves with the actuator 6 (a, b, c) in the pipelines 5 (a, b, c) for supplying the washing water in s responsible filter. In this case, the washing water is supplied to the filters 1 (a, b, c) through the lower distribution device 4 (a, b, c) in the direction from the bottom up and is discharged through the upper distribution device 3 (a, b, c) through the pipelines of the washing water discharge 9 (a, b, c) into the collector for the removal of washing water 19 through an open valve with an actuator 20 for discharge (into the sewer, washing water tank, etc.).

In this case, the check valves 8 (a, b, c) prevent the ingress of water from the washed filter through the piping piping and collectors into the rest

filters that are in standby mode, and through them to discharge, which would violate the flushing mode.

Upon completion of the loosening washing of the last filter, the loading is washed (discharge of the first filtrate) of all filters simultaneously, supplying the source water according to the filtering scheme: through the valve with actuator 14, through the manifold 10 and pipelines 5 (a, b, c), with the valve closed with the actuator 16 rinse water supply. At the same time, the valve with the actuator 18 on the collector for the removal of purified water (filtrate) 17 remains closed, and the filtrate is sent to the discharge (into the sewer, reservoir) through pipelines 9 (a, b, c), and the collector 19 through an open valve with the actuator 20.

After the washing stage, the installation is transferred to the filtering mode by opening the valve with actuator 18 of the filtrate taps and closing the valve 20 of the discharge of washing water.

Installation of water purification by filtration (Figure 2) contains a group of three parallel installed identical pressure (closed) filters 1 (a, b, c) with an upward flow of water containing a heavy granular load (quartz or expanded clay sand, sorption filter material, etc. ) 2 (a, b, c), upper 3 (a, b, c) and lower 4 (a, b, c) switchgears and piping, including pipelines 5 (a, b, c) for supplying water for cleaning with non-return valves 21 (a, b, c), pipelines for supplying washing water to filters 22 (a, b, c) with shutoff valves with water 23 (a, b, c); pipelines 7 (a, b, c) of the outlet of purified water (filtrate) equipped with check valves 8 (a, b, c) and pipelines of the drain of washing water and the first filtrate 9 (a, b, c).

The collector of the water supply for treatment 10 is connected to the feed water supply pipe 11, equipped with an inlet (control) valve 13 and a shutter valve with actuator 14, as well as with the water supply pipelines for treatment 5 (a, b, c) with check valves 21 (a , b, c), the flushing water supply manifold 24 is connected to the flushing water pipe 12, equipped with an inlet (control) valve 15 and to the flushing water supply pipes to the filters 22 (a, b, c), with shutoff valves with a drive 23 ( a B C).

The pipelines for the removal of purified water (filtrate) 7 (a, b, c) are equipped with check valves 8 (a, b, c) and are connected to the collector for the removal of purified water 17, equipped with a valve with actuator 18, and the pipelines 9 (a, b, c ) drain water and the first filtrate are connected to the collector 19 drain

water and a first filtrate equipped with a gate valve 20.

The automatic control system (not shown in the drawing) contains a software device for transferring the installation from the filtering mode to the regeneration (washing) mode of the filter load and automatic control of all stages of regeneration.

Installation of water purification by filtration (Figure 2) works as follows.

In the filtering mode, the purified source water, if necessary pretreated - aerated or with the addition of reagents, is fed to the filters 1 (a, b, c) through the source water pipe 11 with an inlet valve 13 and a valve with an actuator 14, a collector 10 and water supply pipelines for cleaning 5 (a, b, c) with non-return valves 21 (a, b, c) installed on them, through the lower switchgear 4 (a, b, c), they pass through upstream filtration through a granular charge 2 (a, b , c), divert through the upper switchgear 3 (a, b, c) through the pipelines for discharging purified water 7 (a, b, c) with non-return valves 8 (a, b, c) to the collector of purified water 17 and through the valve with actuator 18 to the consumer (diverted to the tank of purified water). All other valves with the actuator are closed.

The installation is transferred to the regeneration mode using remote or automatic control according to a given program.

To put the unit into the regeneration mode of the filter load, close the valve with actuator 14 on the source water pipe 11 and the valve with actuator 18 on the treated water discharge manifold 17. The first stage of regeneration — the loosening washing is carried out sequentially on each filter: the washing water is supplied through the washing water pipeline 12 , through the valve 15 and the valve with the actuator 16 (open for the period of loosening washing) through the collector 24, opening alternately for the time of the loosening of the valve with the actuator 23 (a, b, c) on the supply pipelines 22 (a, b, c) wash water into an appropriate filter. In this case, the washing water is supplied to the filters 1 (a, b, c) through the lower distribution device 4 (a, b, c) in the direction from the bottom up and is discharged through the upper distribution device 3 (a, b, c) through the pipelines for removing the washing water 9 (a, b, c), to the collector for draining the wash water 19 through an open valve with an actuator 20 for discharge (into the sewer, the wash water tank, etc.).

At the same time, check valves 8 (a, b, c) and check valves 21 (a, b, c) prevent water from entering the washed filter through pipe pipelines

strapping and collectors to other filters that are in standby mode, and through them to discharge, which would violate the washing mode.

Upon completion of the loosening washing of the last filter, the loading is washed (discharge of the first filtrate) of all filters simultaneously, supplying the source water according to the filtering scheme: through the valve with actuator 14 through the collector 10 of the water supply for treatment and the water supply pipelines for cleaning 5 (a, b, c ) with non-return valves 21 (a, b, c), with closed valves with actuator 23 (a, b, c) for supplying washing water to the filters. At the same time, the valve with the actuator 18 on the collector for the removal of purified water (filtrate) 17 remains closed, and the filtrate is sent to the discharge (into the sewer, reservoir) through pipelines 9 (a, b, c), and the collector 19 through an open valve with the actuator 20. After the washing stage, the installation is transferred to the filtering mode by opening the valve with the drive 18 of the filtrate outlet and closing the valve 20 for dumping the wash water.

The filtering installation scheme according to this embodiment allows for a certain quality of the source water to apply a combined flushing using the source water supplied through the valve 13 and the valve with the actuator 14 and the flushing (purified water) supplied as described above. This allows to reduce the consumption of purified water for flushing and, accordingly, the performance of flushing pumps (volume of flushing water tanks).

Thus, the proposed technical solutions make it possible to simplify installation, operation, and an automatic control system for plants by reducing the number of valves with a drive while reducing their cost.
