BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 The present invention provides a construction flow chart of a water treatment pipeline subsystem in a circulating water treatment system suitable for a swimming pool. DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0020] Embodiment 1: A circulating water treatment system suitable for a swimming pool, comprising: Water treatment piping subsystem, which undertakes multiple functions such as fluid transportation, pressure resistance, and heat preservation, is a key link in the entire water treatment process. Its construction sequence is: construction preparation → pipeline installation → pipeline support and hanger installation → pipeline segmented pressure test, overall pressure test → pipeline flushing and disinfection → pipeline installation acceptance in stages; Circulating water pump subsystem: The circulating water pump subsystem is used to drive water circulation; Filtration and collection subsystem: The filtration and collection subsystem is used to filter and collect pollutants to ensure water cleanliness; Dosing subsystem: the dosing subsystem is used to add drugs on demand; Disinfection subsystem: The disinfection subsystem is based on medium-pressure ultraviolet disinfection to ensure the sterilization effect and effluent water quality; Heat exchange subsystem: The heat exchange subsystem is used for heat exchange treatment of water bodies.

[0021] Among them, in the construction of the water treatment pipeline subsystem, the pipeline installation construction preparation is specifically as follows: The circulating water supply pipe and return pipe are made of UPVC material, and the standard is that the minimum pressure they can withstand is 1.5 times the maximum working pressure; the pipes are clean and not damaged; Before installation, the pipeline is cut at right angles to the pipeline axis along its length and the edges are polished; the pipe fittings use 90-degree elbows, and the bellows joints and test pressures are in accordance with pipeline technical regulations, with a design life of at least 1,200 reverse movements.

[0022] Among them, in the construction of the water treatment pipeline subsystem, the installation and construction of the circulating water pipeline is specifically as follows: S1: Cutting: According to the coordinates and elevations required by the design drawings, the pipe is cut after positioning and laying out the pipe length. The cut must be flat and perpendicular to the axis. UPVC pipes can be cut with a ratchet milling cutter, a wheel-shaped plastic pipe cutter, an electric saw, or a saw with a good tooth shape. To ensure that the pipe is cut vertically and flat, be sure to use a miter saw box when cutting with a saw. S2: Deburring and beveling: Burrs will prevent proper contact between the pipe and the fittings, and will impose undue stress on the assembly of the pipe and the fittings. Therefore, the burrs and filings inside and outside the pipe must be removed with a grinder. At the same time, a 1-3mm bevel should be made at the end with a grinder to facilitate the next step of installation. S3: Accessory preparation: Wipe off dust and moisture on the accessory sleeve with a clean dry cloth; moisture will reduce the drying speed, and at the same time, too much water will weaken the joint strength during this assembly stage; the dry fit of the pipe and the accessory should be checked; the pipe should be able to easily enter the accessory sleeve 1 / 2 to 3 / 4 deep; if there is a little interference with the bottom of the pipe in the accessory, a solvent adhesive should be used to prepare for the joint; then mark the depth of the socket of the pipe fitting at the insertion end, apply the special UPVC adhesive to the socket first, apply the glue evenly and with consistent thickness along the axial direction, and then apply the plug along the axial direction. When plugging, rotate 1 / 4 of a turn while plugging to the original marking line, press with both hands and hold for a specific time, and then wipe the excess glue around with a cloth. Note that it takes at least 12 hours for the joint to be completely dry and pressurized; S4: Cleaner treatment: When the pipe and pipe fittings are connected, the bonding surface must be cleaned with a special UPVC pipe cleaner; the cleaner should be applied to the outside of the pipe end and the inside of the fitting mouth, and if necessary, the amount of cleaning should be increased to ensure the adhesion of the surface; S5: Bonding and assembly: The special glue for UPVC pipes must be applied after the pipe surface cleaner has finished working, not when it is wet. It is recommended to use the same brand of glue as the pipe; the joint surface must be soaked and softened; the special glue should be applied with a natural bristle brush that is half the size of the pipe diameter; pipes below DN50 can be coated with special glue using a smear tool; a thick layer of special glue should be applied to the outside of the pipe end, and a medium-thick special glue should be applied to the inside of the fitting socket; pipes larger than DN50 should have a second layer of special glue applied to their ends; after applying the special glue, the pipe should be immediately inserted into the fitting socket and rotated 1 / 4 turn; at this time, the fitting should be properly aligned for installation; the pipe must be in contact with the bottom of the fitting socket; the assembly should be maintained in place for 10 to 15 seconds to ensure initial engagement; glue overflow around the joint between the pipe and the fitting should be obvious; if the glue overflow around the socket is discontinuous, it means that insufficient special glue has been applied; the fitting should be discarded and the joint reassembled; excess glue overflow should be wiped off with a rag; S6: Installation and curing: The installation and storage time of the pipe after bonding are affected by the size, temperature, relative humidity and tightness of the pipe. The drier the environment, the smaller the pipe, the higher the temperature, the greater the tightness and the faster the drying time. The assembly must be placed for 1 to 5 minutes without any joint stress, depending on the above conditions. After the initial installation period, the assembly can be carefully loaded and unloaded to avoid obvious joint stress. Special attention should be paid to the assembly of the system under extreme temperature conditions. When the temperature is below 4 degrees Celsius, additional installation and storage time should be given. When the temperature is above 38 degrees Celsius, the assembler should make sure that the adhesive on both sides to be joined is still wet before joining.

[0023] Among them, in the construction of the water treatment pipeline subsystem, the installation and construction of the water treatment valve are specifically as follows: Valves with threaded or flanged connections must be installed in a closed state, and the valve installation direction must be determined according to the flow direction of the medium; the handwheel of the valve on the horizontal pipe section should be installed upwards, and in special cases, it can also be installed horizontally; when the valve is installed with the flange or the butterfly valve is installed, if it is a horizontal pipeline, its bolt holes should be distributed on the left and right of the vertical center, and if it is a vertical pipeline, its bolt holes should be distributed in the most convenient place for operation. It is strictly forbidden to use a hammer or other tools to knock on the sealing surface or valve parts when the valve is assembled with the flange. If welding is required, arcing should be prevented from damaging the flange sealing surface; regardless of the type of valve, the operating mechanism and transmission device should be flexible, accurate, and free of jamming; the installation height and position of the valve should take into account the convenience of maintenance after the system is put into operation. The height is generally 1.2m. When the distance between the center of the valve and the ground reaches 1.8m, it is advisable to arrange it centrally and set up an operating platform. The net spacing of the valve handwheel on the pipeline should not be less than 200mm; the regulating valve of the temperature control system should be installed vertically on the horizontal pipeline, with isolation valves and bypass pipes on both sides. Before the pipeline pressure test, it is advisable to set up a temporary short pipe of the same length, and formally install it after the pressure test is qualified; after the valve is installed, it should be properly kept, and the valve should not be opened or closed arbitrarily. If cross-operation is performed, a protective cover should be added; the flange connection should maintain coaxiality, and the center deviation of the bolt hole should not exceed 5% of the hole diameter, and the bolt should be free to pull. The flange connection should use bolts of the same specification, with the same installation direction, and the tightening bolts should be symmetrical, with uniform force and appropriate tightness.

[0024] Among them, during the construction of the water treatment pipeline subsystem, the specific method of circulating water pipeline pressure testing is: After the pipeline is pre-buried and installed, sub-item and comprehensive water pressure tests are carried out. Generally, tap water is used for pipeline pressure testing. Before pressure testing and flushing, a pressure testing and flushing operation instruction book is prepared according to the on-site conditions, and key links such as water source and discharge point are clarified; Before the pressure test, the pipeline system shall be checked according to the design and construction drawings. Check whether the support is firm, whether the pipeline is a closed system, and other links that may affect the pressure test; Install temporary pressure test pipelines, pressure test instruments and equipment. Set up a venting device at the highest point of the system and a sewage device at the lowest point, and isolate the equipment and valves that cannot participate in the pressure test; During the system water injection process, personnel should be organized to conduct a careful inspection and any problems found should be dealt with in a timely manner. During the system pressure test, the pressure should rise slowly. If any problems are found, the pressure should be released immediately and repairs should not be carried out under pressure; When conducting a water pressure test, release all the air in the pipe, install a pressure gauge at each high and low point, and gradually increase the pressure after filling with water. When the pressure reaches the test pressure value, stop pressurizing and stabilize the pressure for 30 minutes. The pressure drop shall not exceed 0.02MPa. Then reduce the system pressure to the working pressure and conduct an appearance inspection. If there is no leakage, it is qualified. After the pipeline system passes the pressure test, promptly drain the accumulated water in the pipe, remove the blind plates and plugs, restore the system according to the construction drawings, fill out the "Pipeline System Pressure Test Record" in time, go through the acceptance procedures with relevant personnel, and then drain the water in the pipe.

[0025] Among them, during the construction of the water treatment pipeline subsystem, the specific method of the circulating water pipeline water filling test is: The swimming pool circulating water treatment pipeline must be tested for water filling after installation. Before filling the system with water, first plug the outlet of the pipeline discharge point, start from the highest point of the pipeline, slowly inject water into the system, and send people to patrol along the pipeline to see if there is leakage or water. After the system is filled with water for 15 minutes, fill it up again for 5 minutes. It is qualified if the liquid level does not drop. After the water is full, observe whether there is leakage at each interface. If the water level does not drop within 5 minutes, it is qualified. Fill in the closed water test record and go through the acceptance procedures with relevant personnel in a timely manner.

[0026] Among them, the construction method of the circulating water pump subsystem is specifically as follows: Before installation, the foundation of the water pump should be reviewed and accepted. The foundation size, elevation, and longitudinal and lateral deviations of the anchor bolts should meet the requirements of the standard specifications. Then, the water pump should be unpacked and inspected: the parts of the pump should be counted according to the technical documents of the equipment, and records should be kept. If there are any missing parts, the supplier should be contacted to properly resolve them. The protection and plugging of the pipe mouth should be complete. Check whether the main installation dimensions of the pump are consistent with the engineering design. After the water pump is in place, it should be leveled and aligned according to the standard requirements. The water pump piping installation should be carried out after the water pump is positioned, leveled, aligned and stabilized. The water pump equipment shall not bear the weight of the pipeline. The installation order is flexible shock-absorbing joint, hair collector, check valve, the valve is tightened to the water pump in turn, a flange connected to the water pump is tightened to the valve flange, a plumb line is used to straighten and align, the pipe size is measured, the piping is bonded to the flange, the piping flange should be consistent with the flange of the water pump and valve, the direction of the valve wheel should be easy to operate, the elevation should be consistent, and the piping should be arranged neatly; the center position of the water pump inlet should be aligned with the center position of the hair collector outlet; The allowable error of the horizontality of the water pump base (axial) and longitudinal (inlet and outlet directions of the water pump) is 0.1 / 1000 on average; for integrally installed water pumps, the longitudinal installation horizontal error should not be greater than 0.10 / 1000, the lateral installation horizontal deviation should not be greater than 0.20 / 1000, the axial inclination of the horizontal coupling is 0.8 / 1000, and the measurement should be carried out on the inlet and outlet flanges of the pump or other horizontal surfaces; the water pump base should have a shock-absorbing rubber pad, which should be in close contact with the foundation surface; Wherein, the filtering and collecting subsystem specifically comprises: a hair collector and a quartz sand filtering tank; The hair collector is used to intercept solid impurities (such as sand and gravel, swimmers' ornaments, etc.), hair, leaves, fibers, etc. carried in the pool water to prevent them from damaging the pump impeller or entering the filter to block the filter material layer and affect the filtration efficiency and water quality; the hair collector is installed before the water inlet of the water pump, and the center position of the water outlet of the hair collector must be aligned with the center position of the water inlet of the water pump. During installation, attention must be paid to whether the ground at the installation location is flat, and a plumb line and a level ruler must be used to align and level it; after the installation is completed, the weight of the hair collector cannot fall on the water pump; if it is an integrally assembled pump or a special pump for a swimming pool with a conjoined hair collector, it must not be disassembled at will; Among them, the quartz sand filter tank is a precision filtering equipment, which is equipped with a filter unit and can be backwashed with water; the installation sequence is: Check the model parameters of the equipment, conduct basic inspection and acceptance, and fill in the basic acceptance record; the transportation equipment for each tank should be determined according to its weight and size, combined with the on-site conditions; it should be firmly fixed during transportation to prevent bumps and surface damage; the rigging must be inspected and qualified during installation, and the rope length of the sling should be consistent to prevent uneven force and deformation or damage to the tank body; the tank body should be installed flat, straight and straight, and the line should be laid out for positioning before installation; after the tank body is in place, check whether the filter rods and piping in the tank are damaged or loose, and whether the protective paint has fallen off, and install the piping and accessories after passing the inspection; the piping installation of the filter rods should be carried out after the tank body is positioned flat and stable, and the direction of the valve installation handle should be easy to operate and arranged neatly; after the filter piping is installed, fill the corresponding amount of filter material according to the design requirements of the filter and reach the set filter layer height; close the manhole of the filter tank, carefully clean the round mouth surface before covering it, and apply lubricating oil to the nut; Accessory installation: Pressure gauges are installed at the inlet and outlet pipes of the filter respectively. According to the pre-set empirical parameter values, when the difference between the inlet and outlet pressure gauge readings reaches 0.05MPa, the filter is backwashed by switching the valve. The pressure gauge should be oriented in a way that is convenient for reading. New sand filters must be backwashed first and then put into filtering operation after passing water. Remember the number on the pressure gauge when it is used for the first time so as to observe the degree of contamination of the sand bed in the future.

[0027] The specific configuration of the dosing subsystem is as follows: The dosing equipment room and the chemical storage warehouse should be set up in separate and adjacent rooms, and should be close to the circulating water pump. The chemical pump should be placed in a ventilated, shaded and easy-to-maintain place, fixed on the chemical barrel or foundation, and out of the operation and personnel passage.

[0029] One end of the medicine outlet pipe is fixed to the outlet joint of the pump, and the other end is fixed to the dosing pipeline.

[0030] Both ends of the inlet and outlet pipes are equipped with one-way check valves. If the one-way check valve is made of PE or PP, it only needs to be tightened by hand during installation. Wrenches, pipe clamps and other iron tools are prohibited.

[0031] Inspection work before use: Pour an appropriate amount of clean water into the medicine barrel (enough to submerge the filter cover), turn on the pump and check each joint for leaks.

[0032] When there is liquid medicine on the upper part of the pump and its outlet pressure does not exceed the set value, the metering pump can automatically suck liquid. During operation, the capacity adjustment dial must be adjusted to the maximum position (i.e. 100% position), and then adjusted to the appropriate scale according to the actual capacity required.

[0033] Wherein, the disinfection subsystem is specifically configured as follows: The UV sterilizer should be installed horizontally indoors, with the bracket fixed on a designated foundation or workbench. In addition to considering the convenience of water supply and drainage and meeting the process requirements, the location of the sterilization device indoors should also leave enough space and space to pull out the UV lamp.

[0040] (2) The strength, coordinates, elevation dimensions and specifications of the embedded anchor bolts of the plate heat exchanger before it is in place must comply with the design requirements and construction specifications. The heat exchanger bracket should be firmly connected to the bracket, and the bracket should be in close contact with the bracket and the heat exchanger. The allowable deviation of the heat exchanger installation is: coordinate 15mm, elevation ±5mm, verticality (per m) 1mm.

[0041] (3) The plate heat exchanger should be installed firmly, and should be aligned and leveled using a plumb line and a spirit level. The base should be fixed with metal expansion bolts.

[0042] (4) The piping of the plate heat exchanger should be carried out after the heat exchanger is positioned, aligned and stabilized. The plate heat exchanger shall not bear the weight of the pipeline. The outlet pipe shall be made of high-temperature resistant stainless steel pipes and valves. The flange of the pipe connected to the plate heat exchanger should be fastened to the valve flange first, and the plumb line should be used to align and align it, and the size of the pipe should be measured.

After cooling, it should be connected to the valve, and finally the other pipe section connected to the pipe should be welded.

[0043] (5) A pressure gauge and a thermometer shall be installed on the circulating water inlet and outlet pipes of the plate heat exchanger respectively. The pressure gauge dial and the thermometer scale shall be oriented in a direction that is convenient for observation.

[0044] (6) The connection between the heat medium pipeline and the plate heat exchanger should meet the principle that the heat medium flow direction is opposite to the circulating water flow direction.
