Description

A Filtering System for Swimming Pool

The present invention relates to a swimming pool environmentally friendly filtration system, in particular to install a filtration system to filter the pool water in a double environmentally friendly filtration system, characterized in that to save water by minimizing the water going out to the outside It is about.

In general, the pool is shared by many people, so the body oil, sun lotion, chemicals such as body oil, impurities such as manure, foreign bodies such as swimmer's hair, lactic acid alumina or organic / inorganic substances having similar chemical properties As high concentrations of dirts reacted with flocculants, etc., accumulate in a very small amount, greatly reducing the cleanliness of the water and causing contamination due to the decay of these substances, so that water can be continuously filtered to supply purified water to the pool. You should make sure that.

In the past, for filtration treatment, circulating filtration was performed after the opening of the swimming pool until closing, and during filtration, water was introduced into the upper layer by an upstream and downward filtration, and passed through several layers of filter media. This filter is to be re-introduced into the pool, and when filtered for a long time, the filtering capacity is reduced due to the filtering of impurities inside the filter, and backwashing and washing should be performed (usually once a day in the case of a swimming pool) to restore the filtering capacity.

In the case of a swimming pool, after the first day of closing, impurities filtered from the filtration system are discharged according to a process called backwashing and washing. In this case, backwashing and washing are performed using water in a water level control tank to release impurities. In this case, water is supplied to the lower part of the filter. At this time, impurities in the filter float and are discharged to the outside through the upper part of the filter (about 7 minutes). After the backwashing process, the filter material inside the filter is stabilized and impurities introduced into the filter during backwashing are removed. Eject to the outdoors by washing (about 3 minutes) to release.

The amount of water released depends on the freshwater capacity of the pool, and the circulation per minute multiplied by about 10 minutes (approximately 10 minutes with backwashing 7 minutes and 3 minutes of washing) is the amount of water released outdoors from the pool's daily filter. Can be.

Therefore, in order to clean the pool water through the above process, there was a problem that a huge amount of water is consumed.

That is, in the above process, it is necessary to backwash the filter, and for this purpose, a large amount of backwashing water is essentially used, and when the backwashing operation is performed in the above manner, a huge consumption of water is generated as well as in the swimming water. Since the chemicals to be included are consumed and the water warmed to a certain temperature (about 28 degrees) exits to the outside, there is a problem that not only waste of energy but also increase the disposal cost of the discharged sewage and environmental damage.

After all, in order to solve such a problem, the amount of water to escape to the outside should be minimized, but the system up to now has a problem that has to discharge a large amount of water to the outside because the water must be filtered quickly. .

The present invention is to solve the above problems,

The dual filtration system is designed so that backwashing and washing water through the primary filtration system are stored in a separate storage space, and filtration works for a long time in a small secondary filtration system to maximize water savings with a minimum of facilities. Its purpose is to.

As a means for achieving the above object,

The present invention includes a first level control tank for regulating the water level by temporarily storing the excess water from the pool; The first filtration to filter the water drained through one side of the pool to remove foreign substances, add various flocculants and fungicides, heat the water to a suitable temperature and circulate it back to the pool, and release backwashed contaminants containing impurities to the outside. System; A filtrate storage tank for temporarily storing contaminants discharged from the first filtration system; And a second filtration system for refiltering the filtrate output from the filtrate storage tank and inputting the reprocessed water into the level control tank.

The first filtration system includes a collector, a pressure pump, a coagulant injector, a filter, a heater, a pH adjuster injector, and a sterilizer injector to remove relatively bulky foreign matter. It is characterized by consisting of a small collector, a small pressurized pump and a small filter.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram of the present invention, first, the present invention is a level control tank 10, a relatively large first filtration system 20, a filtrate storage tank 30, and a relatively small volume A second filtration system 40 is provided.

The first filtration system 20 includes a first collector 11, a first pressurized pump 12, a coagulant injector 13, a first filter 16, a pH adjusting inleter 14, Sterilizer injector 15, the heater 17 is composed of.

The water level control tank 10 is a place for temporarily storing the excess water from the pool, when the water in the pool overflows will be collected in the water level control tank (10).

The first collector 11 has a function of filtering out relatively bulky foreign matter, and is connected to the water level control tank 10 to receive circulating water from the swimming pool, thereby increasing the volume of hair and metal accessories, etc. Filter out large contaminants.

In addition, the first pressure pump 12 pressurizes the contaminated water passing through the first collector 11 and the water level control tank 10 to be introduced into the first filter 16.

The coagulant control injector 13 administers a chemical to increase the filtration efficiency before the contaminated water is introduced into the filter 16, and the pH control injector 14 and the sterilant injector 15 adjust the pH and sterilize the filtered water. It is put into purpose.

In addition, the first filter 16 filters the contaminated water to circulate the purified water and discharges the contaminated water to the outside, and the heater 17 discharges the water passed through the first filter 16 to a predetermined temperature. Warm it up again.

At this time, the water discharged to the outside is a state in which a fungicide and a pH adjusting agent of a prescribed value is added, and is also heated to a constant temperature.

In the present invention, by sending the water output to the outside to the filtrate storage tank 30 to clean it again by using a secondary filtration system to minimize the polluted water discharged to the outside by making the purified water slowly over a long time In this case, the washed water is sent to the level control tank 10 to circulate to the pool.

The second filtration system 40 is composed of a second collector 41, a second pressurizing device 42 and a second filter 43, and generally has a volume compared to the components of the first filtration system 40. Is much smaller.

The filtrate storage tank 30 is a reservoir for temporarily storing contaminants discharged through the primary filtration system 20, and the second collector 41 has a slight volume in the primary filtered water. The second pressurizing device 42 serves to filter large pollutants, and the second pressurizing device 42 serves to output the contaminated water passing through the second collector 41 by pressure, and the second filter 43 pressurizes the pressurizing device. After passing through the water to wash once again to send to the water level control tank 10, impurities in the second filtration system 40 is connected to the water supply or groundwater and backwashed and washed and discharged.

Looking at the operation of the present invention below.

First, when opening the pipe connected from one side of the pool for filtration of the pool, the contaminants are first passed through the water level control tank 10 to pass through the first collector (集 毛 器), the first collector 11 By the first filtering the material of the size that is not enough to damage the impeller of the first pressure pump 12, for example, fibers such as hair or metals such as hairpins and rings, and the like that is not filtered in the collector The contaminants are secondarily filtered by a first filter 16 via a first pressure pump 12.

In this case, in the case of using a filter using sand, gravel, activated carbon, etc., a coagulant such as aluminum sulfate called alumina alumina is introduced into the pressure pump 12 and the coagulant injector 13 installed between the filter. After contaminants are blocked, they are filtered or passed through a pressurized pump 12 in the case of using a diatomaceous earth filter (adsorbent filter in which diatomaceous earth is adsorbed on a filter cloth provided with a plurality of in series to form a diatomaceous earth membrane). One contaminant is immediately adsorbed on the diatomaceous earth membrane to be filtered, and the water passing through the filter 16 is transferred to the swimming pool to adjust the pH and water sterilization, respectively. Purifying purified water heated to a constant temperature after adding disinfectant or other chemicals such as sodium hypochlorite according to (15). Grade water and contaminated the number included moves in polluted water tank 30. The heater 17 is a heating means for maintaining the water of the swimming pool at 27 to 28 ° C. by applying heat to the water constantly.

The contaminated water moved to the contaminated water storage tank 30 is once again contaminated with the contaminated water through the second filtration system 40, the second collector 41 of the second filtration system 40 After removing the contaminant of a certain size again, and moving the contaminated water with the second pressure pump 42 and filtered again in the second filter 43, the filtered water enters the water level control tank and the secondary filtration The contaminated water is discharged to the outside.

Since the second filtration system 40 is relatively small and runs for a long time, it filters out contaminants as much as possible, enters the filtered water into the water level control tank 10 and consequently returns it to the swimming pool.

Therefore, the primary pool water is first filtered through the first filtration system 20, and the primary filtered contaminated water is again reprocessed through the secondary filtration system 40, and the pool water is added again to the pool. It can minimize the various chemicals contained in it, it also has the advantage that does not need to add a separate thermal energy to heat the pool water, and can reduce the supply of new water and save the drained water.

The embodiment of the present invention is summarized as follows.

In the present invention, the primary filtration system 20 has a relatively large capacity and the secondary filtration system 40 is manufactured with a relatively small capacity. The reason why the secondary filtration system 40 may be small as described above is because the primary filtration system ( This is because only the backwashing and washing water generated in 20) are filtered, and the backwashing and washing water generated in the primary filtration system 20 is usually once a day, and the system is configured to filter until the next occurrence.

For example, if the fresh water in a swimming pool is 500 tons (when it is the most common pool size in Korea), the primary filtration system 20 circulates about 125 tons of water per hour, and the amount of water released during daily backwashing and washing is It is about 21 tons.

If you look at the size and discharge of a universal pool,

Adult pool size: 50m wide 15m long, 1.3m deep, about 487.5 tons, children's pool size: 10m wide, 5m, 0.6m deep, about 30 tons, about 500 tons of fresh water capacity.

Most domestic swimming pools are for profit-oriented swimming pools, which perform about six circulating filtration cycles per day. The calculation of circulation per hour is fresh water x 6 times / 24 hours.

Therefore, in the case of a typical swimming pool, the circulation amount per hour is 125 tons, which is a standard for various mechanical devices, circulation rate per minute, backwash and washing amount.

Thus, the circulation per minute is about 2.1 tons (125 tons / 60 minutes), and 10 tons of water consumes 21 tons of water.

In the secondary filtration system 40, the water discharged from the primary filtration system may be filtered and reused for one day.

Therefore, the magnitude of the secondary filtration system is compared with the hourly circulation rate.

The 21 ton / 24 hour is 0.875 ton, which is a 1/142 (125 / 0.875) filtration system compared to the primary filtration system.

As described above, the present invention can be equipped with a relatively large primary filtration system and a relatively small secondary filtration system to filter the pool water, thereby preventing huge consumption of water, and also providing energy input for heating the pool water. It can minimize the processing costs by reducing the consumption of flocculant, PH regulator and disinfectant, which can reduce the processing cost, reduce the risk of environmental damage and save energy.

Although the present invention has been described in connection with the above-mentioned preferred description, various other modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, the appended claims may be determined to include such modifications and variations as fall within the true scope of the invention.
