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 nature of the proposed installation is a water purification filtering unit containing a group of filters with a granular charge and piping for switching workflows when switching filters from filter mode to regeneration mode of the filter load and vice versa, pipelines for supplying source and washing water, as well as collectors supply of 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. The piping of the filters contains pipelines of source water, wash water, supply water for treatment, drain purified water, supply wash water to the filters and drain the wash 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. In addition, only pressure filters are used in the installation.

The objective of the proposed technical solutions is to reduce the cost of water treatment plants by filtering and simplify the system for their automatic control, installation and maintenance of plants.

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 filters with granular loading and piping with pipelines for supplying water for purification, drainage of purified water, supply of washing water to filters with shut-off valves with a drive and drainage of wash water and first filtrate, feed water pipe, wash water pipe with shut-off valves with a drive, collectors for supplying water for treatment, drainage of purified water and wash water supply, collect OR for washing water and the first filtrate drain and automatic control system, filters are pressure-free with upward filtering, the water supply pipes for cleaning and the washing water supply to the filters are combined, the collectors of the water supply for cleaning and the water supply for washing are aligned, the purified water pipes are provided with return valves, the source water pipeline is equipped with shut-off valves with a drive, and the collector for the removal of purified water is equipped with shut-off valves with a drive or pump.

In particular, in the installation of water purification by filtration, a drainage channel can be used as a collector for draining the wash water and the first filtrate.

According to a second embodiment, in a water purification installation by filtration, comprising a group of filters with a granular charge and piping with pipelines for supplying water for purification, for discharging purified water, for supplying

washing water to filters with shut-off valves with a drive and drainage of washing water and the first filtrate, pipelines of source and washing water, collectors for supplying water for purification, drainage of purified water and supply of washing water, a collector for the removal of washing water and first filtrate and an automatic control system, filters made pressureless with upward filtration, pipelines for supplying water for purification and pipelines for discharging purified water are equipped with non-return valves, the pipeline for source water is equipped with shut-off valves with actuators And purified water outlet manifold provided with a stop valve or pump driven.

In particular, in the installation of water purification by filtration, a drainage channel can be used as a collector for draining the wash water and the first filtrate.

A group of utility models is illustrated by drawings.

Figure 1 shows the technological scheme of the installation for water purification through a group of pressureless filters with upward filtering with combined pipelines for supplying water for purification and supplying washing water to the filters, as well as combined collectors for supplying water for cleaning and flushing; 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 pressureless (open) filters 1 (a, b, c) with an upward flow of water (filtration) containing a heavy granular load (quartz or expanded clay sand) 2 (a , b, c), lower switchgears 3 (a, b, c) with pipelines for supplying water for cleaning 4 to them (a, b, c) combined with pipelines for supplying washing water to filters equipped with shut-off valves with actuator 5 (a, b, c), drainage nodes of purified water 6 (a, b, c), through the pipelines 7 (a, b, c) of the outlet of purified water (filtrate) with check valves 8 (a, b, c) installed on them with a manifold of the outlet of purified water 9, equipped with shut-off valves with a drive (or pump) 10, and nodes for collecting and discharging washing water and the first filtrate 11 (a, b, c), connected through pipelines for draining the washing water and the first filtrate 12 (a, b, c) with a collector for draining the wash water and the first filtrate 13, which

a drainage channel may be used.

The collector of the water supply for treatment 14, combined with the collector of the water supply for flushing, is connected to the pipelines of the source water 15 and the flush water 16, equipped with inlet (control) valves 17 and 19 and shut-off valves with an actuator 18 and 20, respectively, as well as with the supply pipelines water for cleaning 4 (a, b, c), combined with pipelines for supplying washing water to the filters.

The nodes of the removal of purified water 6 (a, b, c) are made in the form of nozzles attached to the filter housings. In large filters, the nodes of the drainage of purified water (cylindrical filters), tray (filters of rectangular cross section) or in the form of a drainage system with perforated pipes.

The nodes of the removal of washing water and the first filtrate 11 (a, b, c) are made in the form of a drainage funnel, and in filters of rectangular cross-section they can be made in the form of a gutter, tray, side pocket, etc.

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 is supplied to the filters 1 (a, b, c) through the source water pipe 15 through the inlet valve 17 and the open valve with the actuator 18, through the collector 14 and the water supply pipelines for treatment 4 (a, b, c) through the lower switchgear 3 (a, b, c), pass through upstream filtration through a granular charge 2 (a, b, c), take it through the purified water discharge unit 6 (a, b, c) through the purified water discharge pipes 7 ( a, b, c) with check valves 8 (a, b, c) into the treated water collector 9 and through an open gate valve with a drive 10 is removed by gravity or by a pump in the reservoir of purified water (consumer). The valve with the actuator 20 on the wash water pipe 16 in the filtering mode is 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 18 on the source water pipe 15 and the valve with actuator 10 on the manifold of purified water 9 (or turn off the pump).

The first stage of regeneration - loosening washing is carried out sequentially on each filter: washing water is supplied through the washing water pipeline 16 through the valve 19 and the valve with the actuator 20 (open for the period of the loosening washing), opening the valve with the actuator 5 (a, b, c) on pipelines for supplying washing water to filters 4 (a, b, c) in the washed filter. In this case, the washing water is fed to the filters 1 (a, b, c) through the lower switchgear 3 (a, b, c) in the direction from the bottom up and is discharged through the washing water outlet 11 (a, b, c) (drainage funnel, tray, etc.) through the wash water discharge pipelines 12 (a, b, c) to the wash water drain collector 13 and to the discharge (into the sewer, the wash water tank, etc.), a drainage channel may be used as the collector 13.

At the same time, check valves 8 (a, b, c) prevent contaminated water from entering the washed filter through pipelines 7 (a, b, c) and the collector 9 into the washed filters, which would violate the subsequent washing regime (would lead to the need to increase the duration of the stage discharge of the first filtrate and its volume).

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 18, through the collector 14 of the water supply for treatment and the water supply pipelines for treatment 4 (a, b, c) when the valve with the actuator 20 is closed, the valve with the actuator 10 on the treated water drain manifold 9 also remains closed (the pump is turned off), and the filtrate is sent to the discharge (into the sewer, reservoir) through the washing water outlet and the first filtrate 11 (a, b, c) (for example, a drainage funnel) through pipelines 12 (a, b, c) and collector 13 (in the downstream channel).

After the washing stage, the installation is transferred to the filtering mode by opening the valve with the drive 10 for the removal of purified water (or by turning on the pump).

Installation of water purification by filtration (Figure 2) contains a group of two parallel installed identical pressureless (open) filters 1 (a, b) with an upward flow of water (filtration) containing a heavy granular load (quartz or expanded clay sand) 2 (a, b ), lower switchgears 3 (a, b) with water supply pipes for cleaning 4 connected to them (a, b) with check valves 21 (a, b) installed on them and piping for washing water to the filters 22 (a, b) ) with valves with actuator 23 (a, b),

nodes of purified water drain 6 (a, b) connected through pipelines 7 (a, b) of purified water drain (filtrate) with check valves 8 (a, b) installed on them with a purified water drain manifold 9 equipped with shut-off valves with a drive or a pump 10, and the nodes of the drain of the wash water and the first filtrate 11 (a, b) connected through pipelines of the drain of the wash water and the first filtrate 12 (a, b) with the collector of the drain of the wash water and the first filtrate 13, which can be used drainage channel.

The collector of water for treatment 14 is connected to the source water pipe 15, equipped with an inlet (control) valve 17 and a shutter valve with actuator 18, as well as with pipelines for water supply for treatment 4 (a, b) with non-return valves 21 (a, b) , the collector of the water supply for flushing 24 is connected to the pipeline for washing water 16, equipped with an inlet (control) valve 19 and with pipelines for supplying washing water to the filters 22 (a, b) with shutoff valves with a drive 23 (a, b).

The nodes for the removal of purified water b (a, b) are made in the form of nozzles attached to the filter housings. In large filters, the nodes of the outlet of purified water can be made in the form of a catchment system with perforated pipes.

The nodes of the removal of washing water and the first filtrate 11 (a, b) are made in the form of a drainage funnel, and in filters of rectangular cross-section they can be made in the form of a gutter, tray, side pocket, etc.

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 is supplied to the filters 1 (a, b) through the source water pipe 15 through the inlet valve 17 and the open valve with the actuator 18, through the collector 14 and the water supply pipelines for treatment 4 (a, b) with installed on them non-return valves 21 (a, b) through the lower switchgear 3 (a, b), pass through the granular charge 2 (a, b) during upward filtration, are discharged through the purified water outlet 6 (a, b) through the purified water discharge pipelines 7 (a, b) with check valves 8 (a, b) into the treated water collector 9 and through the open valve with the actuator 10 take

by gravity or by means of a pump into the tank of purified water (to the consumer).

The valve with the actuator 20 on the wash water pipe 16 in the filtering mode is 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 18 on the source water pipe 15 and the valve with actuator 10 on the manifold of purified water 9 (turn off the pump). The first stage of regeneration - loosening washing is carried out sequentially on each filter: washing water is supplied through the washing water pipeline 16 through the valve 19, opening the valve with the actuator 5 (a, b) in turn at the time of loosening the pipes of the washing water supply 22 (a, b) appropriate filter. In this case, the washing water is supplied to the filters 1 (a, b) through the lower switchgear 3 (a, b) in the direction from the bottom up and is discharged through the washing water outlet 11 (a, b) (drainage funnel, tray, etc.) wash water discharge pipelines 12 (a, b) to the wash water drain manifold 13 and to a discharge (into the sewer, the wash water tank, etc.). As the collector 13, a drainage channel can be used.

In this case, the check valves 8 (a, b, c) prevent contaminated water from entering the washed filter through pipelines 7 (a, b) and the collector 9 into the washed filters, which would violate the subsequent washing regime (would lead to the need to increase the duration of the first stage of discharge filtrate and its volume). Check valves 21 (a, b) prevent the flow of wash water from the washed filter to other filters, which would violate the regeneration 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 18, through the collector 14 of the water supply for treatment and the water supply pipelines for treatment 4 (a, b, c) with closed valves with a drive 5 for supplying washing water to the filters. At the same time, the valve with the actuator 10 on the treated water drain manifold 9 also remains closed (the pump is turned off), and the filtrate is sent to the discharge (into the sewer, reservoir) through the washing water outlet and the first filtrate 11 (a, b, c) ( for example, a drainage funnel) through pipelines 12 (a, b, c) and collector 13 (drainage channel).

After the washing stage, the installation is transferred to the filtering mode by opening the valve with actuator 10 on the purified water outlet manifold 9 (or by turning on the pump).

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.
