Description

  In contrast to many conventional water purifiers that require a water storage tank to store the purified water, the present invention does not require a water storage tank and can be directly connected to tap water to provide purified water. The present invention relates to a water purifier of a reverse osmosis membrane water purifier.

  In particular, in order to make it a direct type, the original low-pressure reverse osmosis membrane water purifier is connected in two stages or multiple stages, resulting in a large amount of purified water. River water and other water can be used as raw water, and can be used as a power source by connecting to the cigarette part of a car other than a household power source.

Currently, household reverse osmosis membrane water purifiers are widely used to remove chlorine and organic substances contained in tap water. However, since most of the water purifiers currently on the market have a small amount of pure water obtained by the reverse osmosis membrane, the purified water is taken out after temporarily storing it in a water storage tank.
There is also an example where heavy metals are removed from raw water during a disaster.
Japanese Patent Laid-Open No. 10-309578 Reverse osmosis membrane water purifier JP-A-11-319827 Reverse osmosis membrane type water purifier Registered utility model No. 3104422 Reverse osmosis membrane water purifier directly connected to water tap JP-A-10-216745 Heavy metal removal device for large-scale disasters

  In conventional reverse osmosis membrane water purifiers, since the amount of pure water obtained through the reverse osmosis membrane is small, it is not possible to connect the water purifier directly to the tap and remove the pure water. It was stored. However, there is a risk that bacteria will be contaminated in the water storage tank, and a space for installing the water storage tank in the kitchen is required, so that it takes a lot of labor and cost to connect to the water pipe. It was seen.

  In order to solve the above-mentioned problems, the present invention is designed for a domestic reverse osmosis membrane water purifier, by combining two or more stages of original reverse osmosis membrane filtration devices and increasing the amount of purified water obtained. Direct reverse osmosis with a pressure pump that provides a means to obtain purified water by directly connecting to a faucet without the need of a tank, and providing raw water from pools, ponds and rivers in the event of a disaster, enabling suction and pumping A membrane water purifier is provided.

  In the present invention, a two-stage or multi-stage original reverse osmosis membrane filtration device is provided, and the internal pressure of the reverse osmosis membrane is controlled to adjust the amount of water so that a large amount of purified water can be obtained.

  When used as a normal water purifier, the pressure switch is activated by the water pressure (0.03-0.07 MPa) by connecting the raw water channel directly to the tap, and the reverse osmosis membrane is pressurized by the pressure pump. I can make water.

  In this case, as a pressure pump, the conventional water purifier has only a pressurizing capacity of about 0.2 to 0.3 MPa, and only 100 to 200 ml of purified water can be obtained in the water storage tank. On the contrary. In the present invention, since it has a pressurizing capacity of about 0.5 MPa to 0.6 MPa, in the event of an emergency due to a disaster, by switching the changeover switch, a powerful pressure pump is activated and the purified water is 400 to 500 ml / min. I was able to get it.

  As a power source, in addition to a normal 100V power source, it can be wired and operated from a cigarette part of an automobile using a commercially available inverter, so that it is convenient for use in a disaster.

The first device is a tap water or pool water, pond water, river water and other raw water channels obtained in the event of a disaster, pre-treatment means with a strainer to remove iron rust and other floating algae, etc., and a pressure switch signal or switch power supply A pressure pump that is driven and controlled by the pressure pump, a sediment filter that is provided subsequent to the pressure pump, and a carbon filter that is provided mainly to remove chlorine and odor, A reverse osmosis membrane filtration device with a first reverse osmosis membrane and a second reverse osmosis membrane connected in series at a relatively low pressure of about 5 kg / cm ² , removes the odor of water after filtration, and adds a trace amount of minerals A post carbon filter, a purified water path for removing filtered purified water, and a waste water path from the reverse osmosis membrane filtration device of the second reverse osmosis membrane A direct-type reverse osmosis membrane water purifier with disaster countermeasures.

  In the second device, the pressure pump is a pump having a pressurizing capacity of about 0.6 MPa, and a direct reverse osmosis membrane provided with a disaster countermeasure that makes it possible to use pools, ponds, rivers, etc. as raw water in the event of a disaster, did.

  In the third device, the pressure switch is turned on when the water pressure is 0.03 to 0.07 MPa, and turned off when the pressure is 0 to 0.03 MPa.

In the fourth device, the reverse osmosis membrane has a pore of 0.0001 micron and uses two or more low pressure membranes having a relatively low pressure of about 5 kg / cm ² , and normally 1.2 liters / liter. Minutes (water temperature 25 ° C.), and 500 ml / min (water temperature 25 ° C.) at the time of disaster.

  In the fifth device, a washing cock and a constant flow valve connected in parallel are provided between the reverse osmosis membrane filtration device and the waste water channel, and the reverse osmosis is eliminated by eliminating the resistance on the reverse osmosis membrane side when the washing cock is used. The surface of the membrane was cleaned.

  In the present invention, in a domestic reverse osmosis membrane water purifier, first of all, combining the original reverse osmosis membrane filtration device in two stages or multiple stages, the amount of purified water obtained is increased, and a conventionally used water storage tank is required. It was possible to provide a means for obtaining purified water directly from the faucet.

  In addition, since it is possible to pump raw water using a pressure pump, water can be absorbed and purified using raw water other than tap water even in the event of a disaster, etc., making the amount of purified water extremely convenient.

(Function)
In the first device, a raw water channel, a water purification channel, and a waste water channel are provided, and usually the raw water channel is connected to a tap of tap water to obtain purified water.

  As a pretreatment process, a strainer that removes iron rust and other floating algae is provided to improve the filtration effect. Furthermore, a sediment filter that removes iron rust and other relatively large impurities and a carbon filter that mainly removes chlorine and odors are provided to maximize the ability of the reverse osmosis membrane.

  As a filtration device of the present invention, a pressure pump driven by a pressure switch has a capacity of 0.5 to 0.6 MPa, and as a normal water purifier, at a water temperature of 25 ° C., at least 1.2 liters / minute, and at the time of disaster, 500 milliliters A large amount of purified water can be obtained by using a combination of the original first reverse osmosis membrane and the second reverse osmosis membrane with a discharge capacity of / min.

  By using a reverse osmosis membrane of 0.0001 micron and connecting a reverse osmosis membrane of about 150 GPD for household use in two stages, purified water of 1.35 liters / minute can be obtained.

  Since the amount of purified water has increased, it can be used by directly connecting to the tap of the water supply, and water from the pool and pond can be used as raw water during disasters.

As the two-stage reverse osmosis membrane, the same one having a filtration action of about 150 GPD can be used, and a pressure of 3 to 5 kg / cm ² is applied. The pressure may be higher in the second reverse osmosis membrane.

  The odor was removed from the filtered water, and purified water was obtained from the water purification channel by passing through a post carbon filter to which a trace amount of mineral was added.

  Waste water from the second reverse osmosis membrane was discharged from the waste water channel.

  In the second device, the pressure pump is a pump having a pressurizing capacity of about 0.6 MPa, and the pool, pond, river and others can be used as raw water at the time of disaster.

  In the third device, the pressure switch is turned on when the water pressure is 0.03 to 0.07 MPa, and turned off when the pressure switch is 0 to 0.03 MPa.

The pressure pump that is driven and controlled by the signal from the pressure switch increases the water discharge capacity, pressurizes at a relatively low pressure of about 3-5 kg / cm ² , and the hole size is about 0.0001 microns, but the surface area is small. A large amount of pure water was obtained by using a filtration means that combined a unique first reverse osmosis membrane filtration device and a second reverse osmosis membrane filtration device having a filtration action of about 150 GPD.

  Therefore, unlike the conventional example, the water storage tank is not required, and the pure water that has passed through the reverse osmosis membrane directly connected to the water pipe can be directly taken out from the faucet.

In the fourth device, the reverse osmosis membrane has a pore of 0.0001 micron and uses two or more low pressure membranes having a relatively low pressure of about 5 kg / cm ² , and normally 1.2 liters / liter. Minutes (water temperature 25 ° C.), and 500 ml / min (water temperature 25 ° C.) at the time of disaster.

  Not only two stages of the first and second reverse osmosis membrane devices but also third, fourth and multi-stage reverse osmosis membrane devices can be provided. However, as a household reverse osmosis membrane water purifier, about two stages are appropriate, and when using a unique reverse osmosis membrane as in the present invention, sufficient filtration and water purification is obtained as a two-stage reverse osmosis membrane water purifier. Is possible.

  Furthermore, in this device, the internal pressure of the reverse osmosis membrane filtration device is adjusted so that the filtration action of the reverse osmosis membrane can be executed in a balanced manner.

  The fifth device is provided with a washing cock and a constant flow valve connected in parallel between the reverse osmosis membrane filtration device and the waste water channel, and the reverse osmosis is eliminated by eliminating the resistance on the reverse osmosis membrane side when the washing cock is used. The surface of the membrane was cleaned.

The reverse osmosis membrane filtration device uses a unique reverse osmosis membrane that increases the discharge capacity by a pump controlled by a normal pressure switch, pressurizes about 3-5 kg / cm ² , increases the surface area to about 150 GPD. The filtration action was performed and the first reverse osmosis membrane device and the second reverse osmosis membrane device were combined to increase the efficiency so that pure water reaching 1.35 l / min was obtained.

  Next, a waste water channel was connected to the second reverse osmosis membrane filtration device via a cleaning cock, and the filtration effect was improved by controlling the internal pressure of the reverse osmosis membrane filtration device and adjusting the flow rate.

  By driving the cleaning cock, the concentrated liquid adhering to the reverse osmosis membrane in the filtration device can be cleaned.

  In the present invention, a reverse osmosis membrane of about 0.0001 micron is used, but a pressure pump having a capacity of 0.5 to 6 MPa is used, and the surface area is larger than that of a conventional reverse osmosis membrane, and a filtration action of 150 GPD is achieved. A reverse osmosis membrane was used. Then, this reverse osmosis membrane was connected in two stages, and the concentrated liquid that was not filtered by the first reverse osmosis membrane was filtered again by the second reverse osmosis membrane so that a filtration action of 1.35 l / min was obtained.

  In addition, the reverse osmosis membrane filtration apparatus showed the two-stage thing on the drawing. This is sufficient for home use, but may be connected in multiple stages to obtain more pure water.
