Description

Group Water Purification Plant {water supplier for a equipment hygiene band}

Hygiene facility for supplying cold and hot drinking water as a large-capacity water boiling facility for supplying drinking water in factories and large-scale personnel

Generally, a water purifier is a device that purifies water according to Article 5, Paragraph 3 of the Drinking Water Management Act, and includes a filter type, distillation type, reverse osmosis type, and ion exchange resin type depending on the purification type.

According to each purification method, there is a method of purifying by gravity method and a method of purifying water by applying the necessary pressure by pressure method.

In the double membrane filter, it is difficult to filter out water by direct pressure, so a pressure pump is required.

This Pembrane filter has the best water purifying ability to filter out impurities in raw water, various ionized heavy metals, and various minerals.

However, there is a disadvantage in that the water purification ability is excellent but the water purification is not possible without giving the necessary pressure to the filter.

Prior arts include "heat-cooled drinking fountains" of Patent No. 0622574, a drinking water supply device of Patent No. 0479559, and a tank-type cold and hot water purifier of Application No. 10-2009-0023502.

Heat-cooled drinking fountain is a method of heating the water in the bucket and then cooling it by using a cooling device.

In the case of the negative water supply device, cold water and hot water can be supplied at the same time, but the temperature of the water is limited and the desired temperature cannot be changed at any time.

Raw water is stored in a tank through a water filter, and a cold heat exchanger is installed in this reservoir to produce cold water, and hot water is extracted from a cold water reservoir to exchange hot water with steam made in a steam generator to produce hot water. There is a disadvantage that bacteria can inhabit the cold water, and there is a structural limit to continuously supplying the cold and hot water at the desired temperature at the same time according to the size of the tank and the heating time of the hot water when continuous hot water is used.

Tank type cold / hot water purifier has purified water and cold / hot / water tank, and water and heating by filter is heated by electric heater and sterilization by ultraviolet lamp.

Disinfection by UV lamp has a variable effect on the speed of water flowing when the lamp is irradiated, and the effect of UV rays irradiated on the tank has a limit on the disinfection effect depending on the water depth in the tank.

Typically, nowadays, small water purifiers are installed in various places, and are heated and cooled by the built-in electric coil, but this is only heated to about 60-80 ° C., so that various viruses or bacteria can be sterilized. Not only can't raise it, but it's also not easy to clean, so it's difficult for the general public to clean it by asking a professional to clean it. If you could not help it.

Moreover, if the cleaning cycle is not met, there is a problem of eating more contaminated water for hygiene.

In particular, drinking water is essential in schools, factories, and places where large people gather, but most of them have small water purifiers installed, and the problem of cleaning water purifiers is frequently broadcasted in the news. It was mostly to buy the water and take it with you to eat.

Existing general water purifier still needs to be improved in terms of convenience of installation, use, maintenance and hygiene.

Patent number 0622574 Heat-cooled drinking fountains describe the method of heating water in a barrel and then cooling it using a cooling device. Patent No. 0479559 Cold water and hot water can be supplied at the same time, but the temperature of the water is limited and the structure can not be changed at any time. Application No. 10-2009-0023502 Tank type cold / hot water purifier has purified water and cold / hot / water tank, and water and heating by filter is heated by electric heater and sterilization by ultraviolet lamp. Disinfection by UV lamp has a variable effect on the speed of water flowing when the lamp is irradiated, and the effect of UV rays irradiated on the tank has a limit on the disinfection effect depending on the water depth in the tank.

Although drinking water is essential in schools, factories, or places where large people gather, most small water purifiers are installed, but they are heated and cooled by the built-in electric coil. Not only does the virus or bacteria propagate but it is also not easy to clean, so it is difficult for the general public to clean it by requesting a professional to clean it, so it is difficult to maintain the cleaning and filter replacement cycles. We are broadcast in news

There are no water purifiers on the market that can boil water, and all the water purifiers have the function of warming to the right temperature, and there are many problems such as not only cleaning the tank but also insects in the water purifier.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a water purifier further improved in terms of hygienic as well as convenience in installation and use and maintenance.

Specifically, the present invention can control the boiling time of water for a suitable time by purifying the water to more than 100 ℃ to make the sterilized water completely sterilized and cooled to the appropriate temperature can be supplied to the desired temperature, especially hot water of 100 ℃ It can supply 4 ℃ supply water in parallel, and can also make barley tea and corn tea.

Cooling water that is boiled above 100 ℃ is cooled by primary cooling, and then cooling by secondary again, and can be arbitrarily adjusted to the appropriate temperature. This makes it easy to check the replacement cycle of the filter at any time, and it is easy to disassemble and clean anyone's heating or cooling heat exchanger.

There are no products that can handle the flow rate when dozens or hundreds of people use the hot and cold water purifiers currently installed on the market and the cold and hot water purifiers installed in large restaurants.

However, the present invention can be manufactured according to the situation to be supplied to hundreds to thousands of people at a time by adjusting the use for a large number of people

Primary water is purified through various filters, and the raw water supplied to the hot water tank is boiled using a direct burner, an electric heater in the tank, or a steam heating device. At this time, sterilization of various viruses and bacteria is performed.

Boiled water is first cooled using an incoming water supply in an alternating heat exchanger, and the heat recovered during cooling is used for preheating the water and the preheated water heated to about 40 ° C enters the tank. In case of heating by burner or steam using steam heating heat exchanger, electric heater, etc., it is heated to 100 ℃ or higher. It is a large-capacity drinking cold and hot water unit package device designed to be integrated with heating and cooling by cooling with an evaporator [direct cooling (or brain circulation method) using a brazed plate heat exchanger.

Conventional water purifiers were difficult to maintain, making it difficult to know the cleaning and replacement cycles of the filter. However, the present invention provides an improved water purifier in terms of convenience and hygiene, and it is easy to clean each tank. The cartridge is easy to observe with the naked eye, so you can check the replacement cycle of the filter at any time, and any heating or cooling heat exchanger can be easily disassembled and cleaned and can be manufactured for use by a large number of people.

By boiling water above 100 ℃, energy can be saved by the amount of heat recovered during the first cooling.

In addition, this device is packaged and installed in a truck, etc., so even in areas where large numbers of personnel can be mobilized, it can be used while moving.

Looking at each one

In the raw water inlet pipe (A), there is a pressurized pump 24 for membrane pressurization, where there is a valve 30 and a bypass pipe 25, and where there is a water pressure suitable for the membrane, it passes through the bypass pipe 25 and is a pressurized pump. 24 is supplied to the filters 3, 4, and 5 from the bypass pipe 25 without being operated.

First, the large-capacity cold / hot water purifier has filters (3, 4, 5), and the cartridge of the prefilter (3) has a structure that can be seen inside, so that the contamination state of the filter can be checked at any time and passes through the filters (3, 4, 5). The purified water is converted into water at 100 ° C. through the heating device 7 and stored in the hot water tank 1. The preheated water retains the recovered heat while being primarily cooled by the water supplied by the hot water cooling pump 9. It has a device in which the water is completely heated in the steam heat exchanger 7 which is a heating device.

Cold and hot water tanks are equipped with an open lid (18) at the top of the tank, the packing is attached to the lid 20 is in close contact with the lid handle (19) anyone can open the tank easily, and within each tank the level control 31) is installed to maintain a constant level at all times.

For the water level control tank, the float type is made of STS material that does not cause rust.

The water level control sensor of the hot water tank and the cooling tank can artificially adjust the water level by the operation panel 27.

The inside of each tank uses STS plate (B) suitable for drinking water, the outside uses 50mm or more of insulation material (32), and it is made of STS plate considering the outer panel conduit and the cold water tank keeps cold water warm and summer It was considered to prevent condensation occurring outside the tank.

Heating device: The steam burner or a direct burner may be installed in the lower part of the tank as in the above example, and the heating source may be selected according to the site conditions by selectively selecting a heater or the like in the tank.

Referring to the illustration shown in this figure based on the heating source by the steam supply pipe 26 is steam and the heating device is a plate heat exchanger (7).

The steam operating pressure of the main island is gauge pressure 2cm2, and the temperature of this steam is about 120 ℃ and sterilization and disinfection is possible with water above 100 ℃ when the ionicity is used as a heating source.

The steam two-sided 15 is a valve device for supplying steam to the steam heat exchanger 7 by proportionally opening the opening degree of the two-sided steam in accordance with the temperature of the water.

When water is supplied for the first time to the water purification device for the first time, water of 100 ° C. heated by the steam heat exchanger (7) is stored in the hot water tank (1) by just passing through the alternating heat exchanger in the raw water supply pipe (A) without heat exchange. After entering the AC heat exchanger (6) by the hot water cooling pump (9) in the hot water tank (1), the hot water is first cooled, and the water cooled to about 40 ° C is stored in the cold water tank (2). It is circulated by the cold water cooling pump 12 to the evaporator 8 and completely cooled and stored in the cold water tank 2.

The hot water of the heated hot water tank is connected to the hot water tank by a hot water cooling pump (9) connected by the hot water cooling pump (9) to cool the primary heat in the AC heat exchanger and circulate from the hot water tank to the AC heat exchanger. The water entered into the AC heat exchanger by the hot water circulation pipe control valve 22 and the check valve 23 through the circulation pipe 21 is stored in the cooling tank with the primary cooling water through the pipe to prevent backflow. It is cooled with water of 4 ° C. by the evaporator 8 which is the secondary cooler of the refrigerator compressor unit 13 by the cooling circulation pump 12.

At this time, the plate heat exchanger for cooling is a brazing plate heat exchanger (8) to be directly cooled by the refrigerant of the refrigerator.

The temperature of the heated water during steam heating is sensed by the hot water sensor 16 installed in the pipe, and at this time, the opening degree of the two-way steam 15 installed in the steam inlet pipe 26 is proportionally opened until the proper temperature is reached.

The opening ratio of the two sides of the steam is automatically proportionally adjusted according to the temperature set value of the operation panel 27 by the signal of the hot water sensor 16 of the hot water pipe connected to the steam heat exchanger.

The raw water heated in this way is sterilized by boiling water of 100 ° C. or higher, such as bacteria or viruses, which may be mixed in the purified water through the filter filters 3, 4, and 5.

The heated water is stored in the hot water tank (1) and enters the AC heat exchanger (6) by a hot water circulation pump (9) connected to the hot water circulation pipe (21), and ionized water is operated to start and stop the hot water cooling pump (9). It is also operated by the set value of the control panel 27.

On the other hand, the user of the cold and hot water purifier according to the present invention, when the cold water stored in the cooling tank is exhausted due to the use of purified water, the incoming water supply passes through the AC heat exchanger and the preheated water is cooled by the steam heat exchanger as a heating device It is operated sequentially by the system while filling the tank

If the filter of the filter part (3, 4, 5) is contaminated by the repeated use of water purifier, it should be replaced with a new one. Periodically, the cold and hot water tanks should be cleaned to prevent water pollution.

The hinge 29 is coupled to the upper lid of the hot water tank 1 and the cold water tank 2 according to the present invention, and is easily opened and closed like a door.

That is, as shown in Figure 1, one edge of the hot water and cold water tank (1, 2) is coupled to the hinge 29 to one edge of the frame and the edge of the lid is tightly sealed by the packing 20 is installed

And one side of the hot water and cold water tank (1, 2), the opposite side of the hinge 29 is provided with a handle 19 that the user can hold.

As a result, when the user grasps the handle 19 and flips the lid, the tank is opened and the inside of the tank is opened and vice versa.

The reason why the sealable lid is connected to the hinge 29 is for convenience of installation and use and convenience of maintenance, and facilitates cleaning of the hot and cold water purifier according to the present invention, thereby cleaning the tank without troublesome work such as disassembly. You can do

At this time, especially by opening the handle 19 attached to the lid 18 of the upper portion of each tank of the cold water purifier according to the present invention and simply finished cleaning the tank, the contaminated water generated after the cleaning is inclined to collect the bottom drain pipe. Open the valve attached to (28) and discard the cleaned water to the outside,

Replacement of the filters (3, 4, 5) can also be efficiently managed, and the cartridge of the filter has a structure in which the inside of the filter is visible so that the degree of contamination of the filter can be checked immediately, so that purified water can be supplied at any time.

All devices are mounted by the lower frame of the arrangement of FIG. 1, but the refrigerator compressor unit 13 is installed outside when the stationary type is fixed, and the refrigerator compressor unit 13 is packaged when used in a mobile vehicle. Can be installed together on the device.

In addition, between each plate of the plate heat exchanger using EPDM thinning agent is a packing agent that is harmless to the human body and can withstand high pressure.

The plate heat exchanger is assembled by selecting the number of sheets required by calculation and the assembly of each plate is supported by STS rod.

Bolts are formed at the end of each rod, and each plate heat exchanger can use the maximum working pressure up to about 32㎠ and the operating temperature is up to 210 ℃.

In addition, it has a fully disassembled assembly structure, making it easy to inspect and replace the heat exchanger plate and gasket.

There is almost no scale generation or contamination in the plate even after long-term use because heat exchange is made by artificially creating strong turbulent flow in the heat exchanger.

The plate heat exchanger has a compact structure and the heat transfer plate 35 of the internal heat transfer portion of the heat transfer plate 35 is designed to overcome the shear stress in which the internal pressure acts on the heat transfer plate because the plate and the plates are close to each other like a checkerboard line. And the edge portion has a good pressure resistance because a gasket 38 compression zone is formed.

The gasket is easily mounted on the heating plate without the use of adhesive.Therefore, there is no process such as adhesive removal when replacing or removing the gasket or cleaning the heating plate, and it is excellent for gasket construction and maintenance. It is not ionized in the water to be dissolved in water does not occur.

The upper connecting rod 33 and the lower connecting rod 39 are connected to the support column and the frames 34 and 36 to serve as a structure in which the plate heat exchanger is upright and as a guide for assembling the heat transfer plate.

It is a large-capacity water brewing facility for sanitary supply of drinking water in factories and large-scale personnel, and can be used simultaneously by hundreds to thousands of large-scale personnel.
