Description
Technical Field
The utility model relates to a reverse osmosis water quality treatment system's technical field, especially a reverse osmosis unit high pressure water supply system of reply undulant quality of water, in particular to system architecture.
Background
Reverse osmosis is a membrane separation operation that uses differential pressure as a driving force to separate solvent from solution. Reverse osmosis is known because it is in the opposite direction to natural osmosis. According to different osmotic pressures of various materials, a reverse osmosis pressure higher than the osmotic pressure can be used, namely a reverse osmosis method, so that the purposes of separation, extraction, purification and concentration are achieved. After the raw water is pretreated, the filtered water is pressed into a reverse osmosis device for purification treatment through a water feeding pump, a cartridge filter and a high-pressure pump, and the discharged water is used for providing residential water or industrial water to achieve the purification effect.
In part coastal areas, surface water and underground water can be periodically subjected to seawater backflow and seawater invasion, when the seawater backflow and the seawater invasion occur, salinity in water can sharply rise, water quality fluctuation is serious, the salinity of inflow water can influence a reverse osmosis membrane when a reverse osmosis device taking the fluctuating water quality as a water source actually operates, when the salinity of inflow water is low, the reverse osmosis device only needs low inflow pressure, and when the salinity of inflow water is high, the reverse osmosis membrane can be ensured to produce the same qualified water by needing higher inflow pressure, so that the upper limit and the lower limit of the salinity of inflow water are simultaneously considered during design to determine the lifts of a feed pump and a high-pressure pump. The existing device achieves the purpose by adding a frequency converter to a high-pressure pump to control the output pressure of the pump.
However, when the fluctuating water quality is dealt with, frequent frequency conversion of the high-pressure pump is not beneficial to stable operation at the highest efficiency point, so that the energy consumption of the system is increased, and meanwhile, the high-pressure pump and a frequency converter matched with the high-pressure pump are expensive, so that the early-stage capital investment can be greatly improved by adopting the frequency conversion of the high-pressure pump.
Disclosure of Invention
An object of the utility model is to provide a reverse osmosis unit high pressure water supply system of reply undulant quality of water suitably improves the lift of frequency conversion feed water pump, reduces the lift of high-pressure pump of deciding frequently to establish the converter for the lower feed water pump of operating pressure, in order to reach the purpose of adjusting reverse osmosis membrane device pressure adaptation ripples quality of water of intaking, reduce the operation energy consumption and fund input in earlier stage simultaneously.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a reverse osmosis unit high pressure water supply system of reply undulant quality of water, the system includes frequency conversion water-feeding pump, safety filter, fixed frequency high-pressure pump, reverse osmosis unit, the delivery port of coagulating sedimentation tank passes through the pipeline and is connected with the water inlet of air supporting pond, the delivery port of air supporting pond passes through the pipeline and is connected with the water inlet of filtering ponds, the delivery port of filtering ponds passes through the pipeline and is connected with safety filter's water inlet, frequency conversion water-feeding pump sets up on the pipeline between filtering ponds and safety filter, safety filter's delivery port passes through the pipeline and is connected with reverse osmosis unit's water inlet, above-mentioned fixed frequency high-pressure pump sets up on the pipeline between.
The utility model discloses a reverse osmosis unit high pressure water supply system of reply undulant quality of water because the low pressure feed pump has configured there is the converter, when reverse osmosis unit leads to the water yield to reduce because of reasons such as water source salinity is undulant, just can adjust the delivery pressure of feed pump through the converter and improve reverse osmosis unit's product water flow, and the system can be applied to sea water desalination, industrial water processing system.
