Swimming pool residual chlorine measurement sensor discharge water recovery system

Abstract

The present invention relates to a water treatment reuse system that recovers and reuses purified hot water discharged from a residual chlorine measurement sensor for swimming pool water quality management, and a control method thereof. Specifically, the stability of the sensor's measured flow rate is ensured by temporarily storing the sensor discharge water in an open-type collection tank, and the drainage pump is automatically controlled according to the detection signal of the water level sensor installed in the collection tank to reintroduce the discharge water into the balancing tank. In particular, it is characterized by the provision of an overflow drain pipe at the top of the sump to prevent flooding even in the event of abnormal situations such as pump failure. Accordingly, the present invention can reduce water usage and thermal energy required for swimming pool operation and improve the operational stability of water treatment facilities.

Description

Technology Field

[0001] The present invention relates to a swimming pool water treatment system and energy saving technology, and more specifically, to a water treatment reuse system that recovers wastewater discharged from a residual chlorine measurement sensor and reintroduces it into a swimming pool circulation system, and a control method thereof. Background Technology

[0002] Generally, residual chlorine sensors installed to maintain swimming pool water quality are configured to allow a constant flow of water to pass through continuously for accurate water quality measurement.

[0003] In this case, the water passing through the sensor is discharged externally without a separate recycling process, which results in the waste of water resources.

[0004] In particular, there is a problem in that the aforementioned discharge water, despite being clean after passing through a filtration system and being heated to match the swimming pool temperature, is discharged as is, causing energy loss.

[0005] Therefore, the development of technology capable of efficiently recovering and reusing wastewater while maintaining sensor measurement conditions is required.

[0006] 5. Description of the Invention

[0007] 5.1 Purpose of the Invention

[0008] The objective of the present invention is as follows.

[0009] · Reduction in water usage through residual chlorine measurement sensors and wastewater recovery

[0010] · Energy savings and carbon emission reduction through the reintroduction of heated water

[0011] · Provides an independent reuse system that does not affect the flow rate measured by the sensor

[0012] · Securing a safety structure to prevent flooding in the event of equipment failure

[0013] 5.2 System Configuration

[0014] The water treatment reuse system according to the present invention includes the following.

[0015] · Sensor discharge line : A pipe that directs water discharged from the residual chlorine measurement sensor to the collection tank

[0016] · Open-air collection tank : Temporarily stores discharge water, and an overflow outlet is formed at the top.

[0017] · Water level sensor : Water level sensor that detects the water level inside the sump

[0018] · Drainage pump : Pressure conveying means for transferring stored discharge water to a balancing tank

[0019] · Refill piping : Pressure pipeline equipped with check valves and shut-off valves

[0020] · Balancing tank connection : Connection point entering the swimming pool circulation system

[0021] 5.3 Key Features and Overflow Countermeasures

[0022] The feature of the present invention is that it is configured so that pump operation does not affect the flow rate conditions of the sensor by applying an open-air collection tank.

[0023] In addition, a double safety structure is provided by forming an overflow drain pipe at the top of the sump to ensure that the discharged water is safely discharged to the outside even in the event of abnormal situations such as a failure of the drainage pump or a power outage, thereby preventing flooding of the facility.

[0024] Furthermore, the present invention is distinguished from existing technologies in that it simplifies the structure by directly reintroducing discharged water without a separate purification process and is a practical, field-oriented technology that can be easily applied to existing swimming pool facilities.

[0025] 6. Effects of the Invention

[0026] According to the present invention, the following effects can be obtained.

[0027] · Water conservation: Annual water savings of approximately 1,986㎥ and operating cost savings of approximately 10 million KRW

[0028] · Energy saving : Heat energy savings and carbon emission reduction through the reuse of heated water

[0029] · Improved operational stability Ensuring safety through overflow structure and backflow prevention function

[0030] · Field applicability : Applicable to existing water treatment facilities without separate major modifications

[0031] Furthermore, the present invention can be extended to various water treatment facilities and sensor-based systems as well as swimming pools, and through the sharing and dissemination of the technology in the future, it can create a virtuous cycle that contributes to energy savings and environmental improvement across public facilities.
