Description

Water purification treatment equipment

Technical Field

The present invention relates to a related apparatus for purifying water.

Background

Various water purifying apparatuses are available on the market, and generally, most of the water purifying apparatuses adopt a mode of filtering water by a filter layer, namely a mode of removing impurities in water by a membrane filter layer. Water and turbid particles were separated through the filter membrane pores with pores of about 10 μm.

In addition, there is also a water purification apparatus for adsorbing impurities in water using activated carbon. The activated carbon can absorb impurities such as organic substances by using a large number of pores. However, activated carbon is generally considered to be a non-polar substance and has a low efficiency of adsorbing ions. However, in recent years, many new results have been obtained from studies on the adsorption of metal ions to activated carbon.

In the patent literature, there are filter containers for performing filtration treatment using a filtration membrane, carbon filter containers filled with filtration carbon, and filter types using both of the above two filtration principles.

In the technique of jp 2004-016893, when the polluted water is treated by the filtering membrane, the filtering capacity of the filtering membrane is often exceeded due to excessive impurities, so that the filtering membrane is blocked, and in addition, in order to maintain the good performance of the filtering membrane, the water pressure suitable for filtering is also required to be adjusted frequently, and if the filtering effect is required to be well solved, the filtering membrane is required to be replaced regularly.

In addition to the filtration membrane, activated carbon is often used for treating sewage, but the efficiency of removing impurities is often lower than that of a filtration system using a reverse filtration membrane, and the adsorption amount of the activated carbon to impurities is also very limited, so that a user often needs to replace the activated carbon or reversely wash the activated carbon in order to maintain the filtration effect of the activated carbon before the adsorption of the activated carbon reaches a saturated state.

Technical content

The invention aims to provide a water purifying device with high-efficiency water purifying treatment capacity for customers corresponding to different water pressures and pollution degrees.

The water purifying device of the invention has the following matching devices in order to achieve the water purifying effect.

There is a raw water inlet pipe into which raw water flows. The ceramic treater is provided with spherical ceramic in 60-80% of capacity, and water flow in the ceramic treater can flow backwards from the lower part to the upper part.

The activated carbon container is provided, and granular or powdery mineral activated carbon is put in 60-80% of the space in the container.

The ceramic water treatment device is provided with an active carbon processor, and treated water flows into the active carbon processor for treatment after being treated by the ceramic processor.

There is a first set of switching valves that controls the direction of the water flow in the activated carbon container, i.e., whether the water flow is from top to bottom or from bottom to top.

There is a water storage tank for storing treated water. For temporarily retaining the treated water. The treated water flows from the upper part to the lower part in the activated carbon container and flows out after being treated by the activated carbon processor.

There is a water flow pipe switcher for determining whether the raw water flowing from the raw water introduction pipe flows into the ceramic treater or the treated water in the water storage tank flows into the ceramic treater.

The control system is mainly used for controlling the first group of switching valves and the second group of switching valves, and the control system is used for determining the working state of the water purifying equipment, namely the working state of purifying raw water or the reverse cleaning working state of cleaning activated carbon.

A control system; in the water purification mode, the first group of switching valves and the second group of switching valves are controlled to enable raw water to flow from bottom to top in the ceramic treater, then flow from top to bottom in the activated carbon container, and finally be discharged from the activated carbon treater as qualified water after water purification treatment. In the reverse cleaning mode, the first group of switching valves and the second group of switching valves are controlled to allow the purified water stored in the water storage tank to flow into the ceramic treater from below to above, then to flow through the activated carbon container from below to above, and then to be discharged from the activated carbon treater to the outside as the drain water.

The water purification mode of the water purification device is as follows: the method comprises the steps of firstly treating the treated water in a ceramic treater, enabling ceramic balls placed in the ceramic treater to rapidly roll and impact each other under the pressure of the treated water, enabling the ceramic balls to mutually impact and electrically react with each other by rolling, enabling impurity structures in the water to be easily changed and enabling impurity substances to be easily separated by utilizing the physical principle, forming the treated water in the state, enabling the treated water to be easily purified in the activated carbon treater when the treated water is treated by the activated carbon, further improving the quality and the efficiency of the purification treatment of the treated water, and enabling the impurities to be easily adsorbed by granular or powdery activated carbon after the treated water is treated by the physical and chemical actions of the ceramic balls in a container and then flows into the activated carbon treater.

In the water purification mode, the flow direction in the activated carbon processor for processing water flows from top to bottom, so that the activated carbon at the inner side is in a compressed state due to the water pressure, and the activated carbon can filter and adsorb impurities in dirty water under the influence of the water pressure.

When the water is treated by the activated carbon, if the water pressure of the treated water is high, the pressure borne by the activated carbon is also increased, and meanwhile, the resistance of the activated carbon to the treated water is also increased, so that the flow rate of the treated water is not increased due to the increase of the water pressure, and conversely, if the water pressure of the treated water is decreased, the compression force of the activated carbon is decreased, the resistance to the treated water is also decreased, and therefore, the flow rate of the treated water is not slower due to the decrease of the water pressure.

In addition, the water purification equipment has the same effect of water purification treatment capability as long as the water pressure of the treated water is high or low and the pollution degree of the polluted water is high or low as long as the water pressure of the treated water is high or low, and the water quality is ensured only by controlling the time problem that the impurity adsorption of the activated carbon reaches the saturation state, thereby knowing that the purifier can deal with water with various water pressures and various pollution degrees, has high water purifying capacity.

In addition, the water purifying apparatus of the present invention is characterized in that when the water is purified again in the reverse washing mode after passing through the ceramic treating tank, the ceramic balls collide with each other in the ceramic treating tank to generate an electric and chemical action on the sewage, so that the dirt in the water is easily removed from the activated carbon when the sewage is treated by the activated carbon. In addition, when the treated water flows into the activated carbon processor to carry out the back flushing mode, the treated water flows from bottom to top in the activated carbon container, so that the compression force of the activated carbon caused by the water pressure of the water purification operation is greatly relieved, the water flow around the spacing holes of each activated carbon is increased, therefore, dirt and impurities adsorbed by the activated carbon can be flushed away, the back flushing large flow has a good separation effect on the activated carbon and impurities, and the impurities and impurities stained by the activated carbon can be smoothly discharged out of the water purification equipment along with the large flow of water.

The ceramic ball stored in the ceramic processor can be in a movable state according to the change of the water pressure of the treated water. The other is that the activated carbon is stored in the container and can change and reverse along with the flowing direction of the treated water, and the compression degree of the activated carbon also changes along with the change of the flowing direction of the treated water.

The equipment is also characterized in that the controller can automatically adjust and switch the pure water treatment mode or the back flushing mode according to the sewage treatment capacity or the sewage treatment time of the activated carbon processor.

The invention has the following effects: the water purifying device can treat sewage with different water pressures and different pollution degrees, has high water purifying capacity and water purifying effect, can also utilize a reverse cleaning mode, avoids using consumables, and efficiently improves the using and regenerating capacity of the activated carbon. Greatly reduces the cost of sewage treatment.

Detailed Description

The working state of the invention is explained in detail with reference to the drawings as follows:

FIG. 1 is a view showing a water purifying apparatus according to a first operation state of the present invention; fig. 2A is a structural diagram of a ceramic processor, and fig. 2B is a structural diagram illustrating an internal state of the ceramic processor.

The water purifier in the first operation state of the present invention comprises a ceramic treater 10, an activated carbon treater 20, a water storage tank 30, a water pump 40, switching valves 51 to 55, a raw water introduction pipe 61 for introducing raw water, pipes 62 to 64 for connecting the respective units, a purified water pipe 65 for discharging purified water W1, a water discharge pipe 66, and a controller 70.

The raw water introduction pipe 61 is a pipe for transporting untreated raw water.

The clean water pipe 65 is a pipe through which the treated water flow is injected into an external device.

The drain pipe 66 discharges the treated water used for washing the activated carbon K in the reverse washing mode.

The ceramic treater 10 is a main part for generating electricity and chemical action of the treated water W, and the ceramic treater 10 is a vertical pipe body as shown in figure 2, a plurality of ceramic balls are placed in the pipe body, the diameter of each ceramic ball is 2.5-50 mm, and the ceramic balls are spherical and have high hardness.

The ceramic balls S contained in the ceramic treating apparatus 10 have the same diameter, and 60% to 80% of the volume space of the ceramic treating apparatus 10 contains the ceramic balls S.

In the water treatment process, the ceramic treater 10 is filled with the treated water W, and the treated water W flows upward from below, so that the ceramic balls can move freely in the pipe body by the water flow. When the treated water W does not flow, as shown in fig. 1, the ceramic balls are deposited at the lower portion of the inside of the pipe body in a range of 60% to 80%, and when the treated water flows, as shown in fig. 2B, the ceramic balls collide with the inside of the pipe body repeatedly at a high speed due to the water pressure, thereby generating an electrical and chemical action.

The activated carbon treatment device 20 is a device for adsorbing impurities in treated water W by using activated carbon K, and the activated carbon treatment device 20 is a container having a larger space diameter than a ceramic treatment pipe body and filled with activated carbon K, which is a granular or powdery object.

The internal structure of the activated carbon treatment apparatus 20 is not particularly limited as shown in fig. 3, and the present invention is configured such that the pipe 22 is composed of a mounting pipe 22 and a filter 23, a suction/discharge port 24 capable of discharging the treated water W is mounted on the upper portion of the housing of the activated carbon treatment apparatus 20, and the pipe 22 extends from the upper plug 21 to the lower portion of the housing through the middle of the housing. The filter 23 is constructed to fix a portion of the activated carbon to allow a water flow to smoothly pass therethrough, and is constructed of a wire net, and is placed at a lower portion of the container to be connected to the pipe 22, and the suction/discharge port 24 is not particularly limited, and is generally mounted to the plug 21.

The activated carbon processor 20 can switch the flow state of the treated water W from the top to the bottom or from the bottom to the top. In the case of the top-down flow mode, the treated water W flows into the activated carbon treatment apparatus 20 through the suction/discharge port 24, passes through the filter 23 and the pipe 22, and is discharged to the outside of the activated carbon treatment apparatus 20. When water flows upward from below, the water flows through the filter 23 and the pipe 22 and then flows into the tubular activated carbon treatment device, and the treated water is discharged from the suction/discharge port 24 to the outside of the activated carbon treatment tube 20.

The container of the activated carbon processor 20 is an activated carbon container, which is a part of the container except the pipe 22 and the filter 23, and the activated carbon K is placed in the container, and the activated carbon K placed in the activated carbon processor 20 occupies 60% to 80% of the internal space, and the activated carbon K is placed in the container in a non-fixed and loose manner.

The water storage tank 30 temporarily stores the water W1 purified by the carbon treatment apparatus, and the purified water W1 is supplied to the outside through the purified water pipe 65.

The water pump 40 injects purified water W1 into the ceramic and activated carbon processors while in the backwash mode.

The switching valves 51-55 are electromagnetic valves for controlling electrical switches, wherein the first group of electromagnetic valves 51-53 are water flow switching valves for controlling whether the treated water W flows from top to bottom or from bottom to top in the activated carbon treater, the switching valves 51-53 can also be installed on the bolt body 21 of the ceramic treater 10, the switching valves 51-53 are characterized by consisting of three-phase valves and switching valves, the three-phase valves can also replace two switching valves, and the specific equipment can be changed according to different structures.

The second group of switching valves 54 and 55 mainly controls whether raw water or water in the reservoir 30 is used when the treated water W is injected into the ceramic treating apparatus 10. The switching valves 54 and 55 are characterized by being composed of three-phase valves and switching valves, and can be adjusted according to required structures.

The control system 70 primarily controls the operation and stop of the water pump 40. At the same time, the switching valves 51-55 can also be controlled.

The operation states of the washing mode and the backwashing mode will be described below.

A water purification mode:

the water purification system is a system for purifying raw water by the present technology, in which the control system 70 controls the flow direction of the treated water W in the activated carbon treatment apparatus 20 by changing the switching valves 51 to 53, the injection system is a system in which the treated water flows from the top to the bottom, and the control system 70 controls the supply of raw water to the ceramic treatment apparatus by switching the switching valves 54 and 55 and the water pump 40.

As shown in fig. 1, the control system 70 is mainly used for controlling the switching valve 54 to open and close the raw water introduction pipe 61 and the ceramic treater 10 and to cut off the pipe 64 and the ceramic treater 10, and the control system 70 controls the switching valve 51 to open and close the pipe 62 and the suction/discharge port 24 of the activated carbon treater 20 and to open and close the pipe 62 and the pipe 22. The control system 70 is also used to control the switching valve 52 to be opened, the switching valve 53 to be closed, and the switching valve 55 to be opened, thereby putting the water pump in a non-operating state.

According to the above operation principle, the ceramic treater 10 injects the treated water W from the lower side to the upper side of the ceramic treater 10 by using the water pressure of the raw water, the ceramic treater 10 is smaller than the activated carbon treater 20 by more than half, and the flow rate of the treated water W in the ceramic treater is very high compared with the flow rate of the activated carbon treater 20, so that the ceramic balls S are violently rolled in the container and repeatedly collide with each other, thus causing the treated water flowing around to generate an electric and chemical reaction, and it is considered that the treated water W contains a property of easily separating impurities due to the electric and chemical reaction.

The treated water W treated by the ceramic ball violent rolling of the ceramic treater 10 is flowed into the activated carbon treatment device 20 for water treatment again, when the treated water W flows into the activated carbon treatment device 20, the treated water W flows in from the upper suction and discharge port 24, the water flows through the activated carbon placing part from top to bottom, passes through the lower filter 23 and the pipe 22 and is discharged outside the device, when the treated water W flows through the activated carbon containing part, the activated carbon K is compressed by the pressure of the treated water to become a little void, and the treated water W flows through the gap of the activated carbon K while being subjected to the resistance of the activated carbon.

Here, the impurities in the treated water W are very easily separated by the influence of the electric and chemical actions generated by the violent movement of the ceramic balls in the ceramic treater 10, so that the impurities in the treated water W are adsorbed and adhered by the activated carbon in a very high efficiency during the flow of the treated water W through the gaps of the activated carbon K, and thus the treated water W is purified.

In the process of flowing through the activated carbon, the separated impurities are continuously attached to the activated carbon W, the phenomenon is that the impurities on the upper layer of the activated carbon are the most, but the impurities are less the further downwards, and therefore, the treated water W can still achieve the water purification effect through the treatment of the activated carbon on the middle and lower layers. In the process of water purification treatment, the activated carbon K can not be stirred, so that the water purification operation can still be carried out under the condition that attachments are adhered to the upper layer of the activated carbon.

The water W purified by the ceramic treatment apparatus 10 passes through the filter 23 and the pipe 22, flows from the ceramic treatment apparatus 10 to the water storage tank 30, and the water W1 in the water storage tank 30 can be supplied to the outside through the clear water pipe 65.

As the water treatment capacity of the water purification system increases, the amount of impurities deposited and adhered on the activated carbon K increases, and the water purification capacity of the uppermost layer of the activated carbon K gradually decreases, but the water purification capacity of the uppermost layer of the activated carbon K is decreased, and the activated carbon K from the middle layer to the lower layer maintains a high water purification capacity, and thus a good water purification effect can be maintained.

For the quality guarantee period of the water purification capacity of the activated carbon, the technology can calculate the water amount of the treated water W, the pollution degree of the water and the amount of the activated carbon K, and according to the calculation result, the automatic control system can convert the water purification capacity of the activated carbon treatment device 20 into the reverse cleaning mode of the activated carbon K before the water purification capacity is reduced, so that the activated carbon is regenerated and cleaned.

A reverse cleaning mode:

FIG. 4 is a schematic view showing the flow of treated water in the reverse cleaning mode of the water purification apparatus in the 1 st operation state.

The reverse cleaning mode is a regeneration operation mode in which impurities deposited on the surface or inside of the activated carbon K are cleaned and the activated carbon is returned to the water treatment effect. In the reverse cleaning mode, the control system 70 controls the switching valves 54 and 55 and the water pump 40 to switch the operation thereof so that the purified treated water W1 flows into the ceramic treating apparatus 10, and the control system 70 controls the switching valves 51 to 53 to switch the operation thereof so that the treated water W1 flows upward from below the activated carbon treating apparatus.

As shown in fig. 4, the control system 70 controls the switching valve 54 to adjust the operation of the apparatus, i.e., to cut off the water flow between the raw water inlet pipe 61 and the ceramic treater 10 and to connect the pipe 64 and the ceramic treater 10, and the control unit 70 controls the switching valve 51 to cut off the connection between the pipe 62 and the suction/discharge port 24 of the activated carbon treater 20, to connect the pipe 62 and the pipe 22, and at the same time, the control system 70 closes the switching valves 52 and 55 and opens the switching valve 53 to set the water pump 40 in an operating state.

The operation control switching state is changed, in the ceramic treater 10, the treated water W1 after water purification treatment flows from bottom to top by the pressure of the water pump 40, and the water flow causes the ceramic balls S to violently roll in the tubular container and repeatedly collide with each other, so that the electricity and chemical reaction of the treated water W of the surrounding water flow is caused, the electricity and chemical reaction is remained in the treated water W1, and the treated water W has the property of enabling impurities attached to the activated carbon to be easily washed away.

Treated water W1 treated by the ceramic treater 10 is injected into the activated carbon treater 20, and in the activated carbon treater 20, treated water W1 flows into the filter 23 through the pipe 22, flows from the lower part to the upper part of the activated carbon, and is discharged to the outside through the suction/discharge port 24, and when treated water W flows through the activated carbon treater, the pressure of the treated water W1 is upward, so that the compression force of the activated carbon K is relieved, and the gap between the activated carbons is expanded by the pressure of the water from the lower side.

It should be noted here that, due to the chemical action of the charges generated by the processing water W processed by the ceramic processor 10, the impurities adhered to the periphery of the activated carbon can be easily removed, and the impurities are washed away by the processing water, and further, due to the backflow of the water flow from bottom to top, the intervals between the substances of the activated carbon K are enlarged, so that the water flow K around each activated carbon K is more smooth, which is more beneficial to washing.

The treated water W2 flows through the activated carbon K and then flows to the upper part of the activated carbon 20 processor, the water contains a lot of impurity impurities, and then is discharged to the outside through the suction and discharge port 24 and the water discharge pipe 66 of the activated carbon 20, the activated carbon K does not generate stirring phenomenon in the treatment process, due to the high-efficiency cleaning treatment mode, compared with the water quantity of the purified water treatment, the activated carbon can be regenerated by using very little treated water W1, and the original working state can be recovered.

As described above, the water purifying apparatus in this operation state has high water purifying capacity and excellent water purifying effect by using the water treatment technologies of the ceramic treatment device 10 and the activated carbon treatment device 20, and can treat sewage of various water pressures and various pollution degrees by using the purification technology of the activated carbon treatment device 20, and has the same purifying capacity and the same water purifying effect under the conditions of different water pressures and different pollution degrees.

As described above, the purification apparatus using the present technology can perform the backwashing operation, and the activated carbon K in the activated carbon processor 20 is subjected to the washing operation from bottom to top using the treated water W1, and it is worth pointing out that the treated water W1 used for cleaning the activated carbon can be returned to the ceramic processor 10 after being subjected to the water purification treatment again after backwashing the activated carbon, and can be recycled as the treated water again, so that the activated carbon can be regenerated and used by the backwashing technology, and the utilization rate of the activated carbon is greatly improved.

The 2 nd operating state:

fig. 5 is a schematic view showing a water purifying apparatus according to the 2 nd operation mode of the present invention. In the 2 nd operation state, the control system 70A and the water flow integrators 71 and 72 are different, and the other configurations are the same as those in the 1 st operation state, and detailed description thereof will be omitted here

The water amount integrator 71 of the 1 st stage is mainly used for transmitting an integrated measurement data signal for the water purification process, and for example, measures and calculates the amount of water flowing through the pipe 63 and transmits the value of the calculation result. The water amount totalizer 71 can also be attached to other piping that requires the use of the activated carbon treatment device 20 while totalizing the amount of water treated by the purified water.

The 2 nd water volume integrator 72 is mainly used for transmitting a data signal for calculating the amount of reverse cleaning water, for example, data for measuring the amount of water flowing through the piping 66. The water amount totalizer 72 can also totalize the amount of water used for backwashing the activated carbon processor 20 and can also be attached to another piping for the purpose.

The control system 70A calculates the amount of water required to start the water purification operation after the activated carbon K is regenerated and flushed the last time, using the data obtained from the purified water integrator, obtains a set value according to the amount of water used, and controls the water purification apparatus to switch the operation mode, that is, when the water purification apparatus is switched from the water purification mode to the backwashing mode, using the set value, the set value being set in consideration of the worst water treatment environment, in consideration of the condition that the impurity adsorption of the activated carbon K is excessive, and in consideration of the range of the water treatment capacity allowable value of the activated carbon processor 20. The control system 70A can refer to the integrated water amount data and the time information, and control the activated carbon backwashing operation time by the automatic switching system, thereby making it possible to schedule the activated carbon backwashing operation to the night when the amount of water required for the water purification process is relatively small.

Then, the control system 70A integrates the amount of water used for regeneration and washing of the activated carbon by using the obtained back-washing water amount usage signal data, changes the integrated amount into a set value, and automatically switches the time for switching from the back-washing mode to the water purification mode according to the set value.

In addition, if the unit time of the water purifier is constant and the amount of purified water used per day is constant, the control system 70A may determine the operation program for automatically switching the back-washing of the activated carbon according to the number of days or time without using the water volume integrator. In addition, the control system 70A may perform water volume integration processing and may operate instead of a water meter.

As mentioned above, the water purifier in the 2 nd working state can select the optimal time period to carry out the active carbon back-washing operation, thus reasonably solving the problem that the back-washing mode is influenced by switching during the busy water purification operation in the daily water purification operation.

The operation of the respective configurations of the present invention has been described above, and actually, the present invention is not limited to the above-described apparatus configuration and operation state, and for example, in the configuration of the present invention, the pipe 22 is extended downward from the upper portion of the middle of the activated carbon treatment apparatus 20 in order to discharge the treated water from the lower portion of the activated carbon treatment apparatus 20, but a configuration may be devised in which a pipe is connected to the lower side of the activated carbon treatment apparatus 20, and the treated water is discharged from the lower side of the activated carbon treatment apparatus 20 through this pipe, and other details of the present invention may be appropriately modified without departing from the object of the present invention.

The following are the relevant data of the water purification capacity and the back-flushing purification capacity of the water purification device:

the water purifying device comprises the following components: a ceramic cylindrical processing apparatus 10 (diameter 300mm, height 1600mm), and a carbon processing bath 20 (diameter 1200mm, height 2400 mm).

Table 1 shows the actual water purification capacity of the water purifier after repeating the water purification treatment and the backwashing treatment of the present technology for 3 months

As can be seen from the table i, the water purification apparatus according to the present technology can efficiently remove dissolved substances from raw sewage while maintaining high purification ability after repeating water purification and backwashing.

The present invention can be applied to a treated water purification system in terms of industrial applicability.
