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.

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 the second embodiment, in a water purification installation by filtration, containing a group of filters with a granular charge and piping with pipelines for supplying water for purification, drainage of purified water, supply of wash water to filters with shut-off valves with a drive, drain wash water

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 by filtration through a group of contact clarifiers - filters with upward water filtration, pre-treated with reagents (coagulant, coagulant and flocculant, chlorinated) and combined pipelines for supplying water for purification and supplying washing water to the filters, and also combined collectors of water supply 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 contact clarifiers 1 (a, b, c) with upward filtration (water flow) containing a heavy granular charge (quartz or expanded clay sand, sorption filter material, etc. ) 2 (a, b, c), lower 3 (a, b, c) switchgears, drainage units for treated and rinse water and the first filtrate 4 (a, b, c) and piping, including pipelines for supplying water for treatment 5 (a, b, c) combined with flushing water supply pipelines filters with shutoff valves with actuator 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 supply pipes of the source water 11 and the flushing

water 12, equipped with inlet (control) valves 13 and 15 and shut-off valves with actuators 14 and 16, respectively, as well as with pipelines for supplying water for cleaning 5 (a, b, c), combined with pipelines for supplying washing water to filters with shutoff valves with drive 6 (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 an actuator 18 or a pump, and pipelines 9 (a, b c) drainage of the wash water and the first filtrate are connected to the collector 19 of the drain of the wash water and the first filtrate, which can be used as a drainage channel.

The nodes of the drainage of purified and wash water and the first filtrate 4 (a, b, c) can be made in the form of side pockets with a pipe for drainage of purified water 20 (a, b, c) and a pipe for drainage of wash water and the first filtrate 21 (a, b , c) located above the outlet pipe for purified water.

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 11 with an inlet valve 13 and a valve with an actuator 14, a collector 10 and water supply pipelines for treatment 5 (a, b, c) through the lower distribution devices 3 (a, b, c), pass through upstream filtration through a granular charge 2 (a, b, c), are discharged through the purified water outlet 4 (a, b, c) through the purified water discharge pipelines 7 (a, b , c) with check valves 8 (a, b, c) into the collector of purified water 17 and through an open valve with actuator 18 is diverted to or a reservoir of treated water is fed by a pump to the consumer. 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 collector for the removal of purified water 17 (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 12, through the valve 15 and the valve with the actuator 16 (open for the period of loosening washing), opening in turn for the time of loosening of the valve with the actuator b (a, b, c) on the pipelines for supplying washing water to filters 5 (a, b, c) in the washed filter. In this case, the washing water is supplied 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 unit 4 (a, b, c) through the pipelines for removing the washing water 9 ( a, b, c) to the collector of the outlet for washing water (or the outlet channel) 19 for discharge (into the sewer, the tank for washing water, etc.).

At the same time, check valves 8 (a, b, c) prevent water from entering the washed filter through piping pipework and collectors into the remaining filters, which would lead to the ingress of contaminated water into the washed filters and increase the duration of the washing washing stage.

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, in). In this case, the valve with the actuator 18 on the collector for the removal of purified water (filtrate) 17 remains closed, and the filtrate is directed to the discharge (into the sewer, reservoir) through pipelines 9 (a, b, c), and to the collector 19 (or along the drainage channel ) to discharge (into the sewer, tank).

After the stage of dumping the first filtrate, the installation is transferred to the filtration mode, for which the valve with the actuator 18 is opened on the collector for the removal of purified water 17 (or the pump is turned on).

Installation of water purification by filtration (Figure 2) contains a group of two parallel installed identical contact clarifiers 1 (a, b) containing a heavy granular load (quartz or expanded clay sand, sorption filter material, etc.) 2 (a, b), lower distribution devices 3 (a, b), nodes for the removal of purified and wash water and the first filtrate 4 (a, b) and piping, including pipelines 5 (a, b) for supplying water for treatment with check valves 22 (a, b), pipelines for supplying washing water to filters 23 (a, b) with shutoff valves with drive 24 (a, b); pipelines 7 (a, b) for discharging purified water (filtrate) equipped with check valves 8 (a, b) and pipelines for discharging washing water and the first filtrate 9 (a, b).

The collector of water for treatment 10 is connected to the source water pipe 11, equipped with an inlet (control) valve 13 and a shutter valve with actuator 14, as well as with pipelines for water supply for treatment 5 (a, b) with non-return valves 22 (a, b) , the collector of the water supply for flushing 25 is connected to the pipeline for washing water 12, equipped with an inlet (regulating) valve 15 and with pipelines 23 (a, b) for supplying washing water to contact clarifiers with shut-off valves with actuator 24 (a, b).

The pipelines for the drainage of purified water (filtrate) 7 (a, b) are equipped with check valves 8 (a, b) and are connected to the collector for the drainage of purified water 17 equipped with a valve with an actuator 18 or a pump, and the pipelines for drainage of the wash water and the first filtrate 9 (a) , b) are connected to the collector 19 of the outlet of the wash water and the first filtrate, which can be used as a drainage channel.

The nodes of the removal of purified and wash water and the first filtrate 4 (a, b) can be made in the form of side pockets with pipes for the removal of purified water 20 (a, b) and pipes for washing water and the first filtrate 21 (a, b) located above the pipes drainage of purified water 20 (a, b).

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 11 with an inlet valve 13 and a valve with an actuator 14, a collector 10 and water treatment pipelines 5 (a, b) with check valves 22 (a , b) through the lower switchgear 3 (a, b), pass through upstream filtration through a granular charge 2 (a, b), discharge through the node for the treatment of purified water 4 (a, b) and nozzles 20 (a, b) through pipelines drainage of purified water 7 (a, b) with check valves 8 (a, b) into the collector of purified water 17 and through open s with a drive engine 18 is withdrawn into the reservoir or purified water is supplied by a pump to the consumer. 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 collector for the removal of purified water 17 (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 pipe 12, through the valve 15, opening in turn for the time of loosening of the valve with the actuator 24 (a, b) on the pipe 23 (a, b) of the washing water supply into the 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 to the top and is discharged through the unit 4 (a, b) and the pipe 21 (a, b) through the pipelines for draining the washing water 9 (a, b) to the collector for the removal of wash water 19, which can be used as a drainage channel, and then to the discharge (into the sewer, wash water tank, etc.).

At the same time, check valves 8 (a, b) prevent water from entering the washed filter through piping piping and collector 17 into the remaining filters, which would lead to contaminated water entering the washed filters and increasing the duration of the washing washing stage.

Upon completion of the loosening washing of the last filter, the loading is washed (discharge of the first filtrate) of all filters at the same time, supplying source water according to the filtering scheme: through a valve with actuator 14, through manifold 10 and pipelines 5 (a, b) for supplying water for cleaning. In this case, the valve with the drive 18 of the purified water outlet remains closed (the filtrate drain pump is turned off), and the purified water is sent through pipelines 9 (a, b), and to the collector 19 (or through the drainage channel) for discharge (into the sewer, reservoir) .

After the stage of dumping the first filtrate, the installation is transferred to the filtration mode, for which the valve with the actuator 18 is opened on the collector for the removal of purified water 17 (or the pump is turned on).

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.
