Description

Technical Field

[0001] This invention relates to the field of seawater desalination equipment technology, specifically a seawater desalination device with adjustment and control functions. Background Technology

[0002] Seawater desalination technology is one of the important means to alleviate the global shortage of freshwater resources. With the continuous increase in the world's population and the acceleration of industrialization and urbanization, the problem of freshwater shortage is becoming more and more serious. How to achieve seawater desalination efficiently and economically has become an important research topic.

[0003] Traditional seawater desalination technologies mainly include distillation, electrodialysis, and reverse osmosis. Among them, reverse osmosis is widely used due to its advantages such as low energy consumption, high processing efficiency, and simple and compact equipment.

[0004] However, existing seawater desalination equipment still has many shortcomings in actual operation. First, the marine environment is complex and changeable, especially in environments with large waves. Seawater intake is easily affected by fluctuations, leading to unstable water intake. Furthermore, the intake is prone to clogging by algae and large floating debris, reducing the reliability and efficiency of the system. In addition, the pretreatment stage often suffers from insufficient filtration efficiency and difficulty in replacing filter media, easily leading to unstable pretreated water quality and thus reducing the lifespan of the reverse osmosis membrane. Moreover, current reverse osmosis membranes are difficult to adapt to the needs of long-term continuous operation, are prone to membrane fouling and clogging, requiring shutdowns for maintenance, resulting in frequent maintenance, high costs, and significant fluctuations in water quality. Therefore, those skilled in the art have provided a seawater desalination device with regulation and control functions to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a seawater desalination device with adjustment and control functions to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The seawater desalination equipment includes an intake unit, a pretreatment unit, a reverse osmosis conditioning unit, and a membrane surface cleaning unit. The intake unit and the pretreatment unit are connected, the pretreatment unit and the reverse osmosis conditioning unit are connected, and the membrane surface cleaning unit and the reverse osmosis conditioning unit are tightly connected.

[0008] By employing the above technical solution, the intake unit is responsible for efficiently and stably extracting seawater from the marine environment and performing primary filtration to effectively block large particles and algae, preventing them from entering subsequent processes. The pre-filtered seawater is then transported through pipelines to the pretreatment unit, where it undergoes further fine mechanical filtration, chemical treatment, and sterilization, effectively reducing particulate matter content and microbial count, significantly improving the operating efficiency of the subsequent reverse osmosis process and extending the membrane module's lifespan. Subsequently, the fully pre-treated seawater is smoothly transported from the pretreatment unit to the reverse osmosis regulation unit. This unit, by precisely controlling the permeate flow rate, membrane surface pressure, and the operating status of the wound membrane module, significantly improves the membrane surface permeability, ensuring a stable production of high-quality freshwater. The membrane surface cleaning unit is tightly connected to the reverse osmosis regulation unit, periodically and effectively cleaning the reverse osmosis membrane surface, thoroughly removing impurities and deposits, preventing membrane clogging, and maintaining the membrane's high permeability performance over the long term. Overall, this equipment achieves efficient seawater desalination, extends equipment lifespan, reduces maintenance costs, is stable and reliable, and is suitable for long-term industrial operation.

[0009] Furthermore, the intake mechanism includes an intake cylinder, a transmission assembly, a filter screen, an intake water pump, an impeller, an auxiliary motor, an intake pipe, and a base.

The auxiliary motor and the intake cylinder are fastened together. The auxiliary motor and the impeller are driven together. The base and the intake cylinder are fastened together.

[0010] By adopting the above technical solution, the intake mechanism obtains seawater to be desalinated from the ocean through the inlet of the intake cylinder. The intake cylinder is equipped with a filter screen to initially filter large particles of impurities from the seawater, preventing them from entering subsequent systems. An intake pump transports the pre-filtered seawater to the pretreatment unit through an intake pipe; simultaneously, an auxiliary motor drives an impeller to rotate, improving the efficiency of seawater intake. The transmission assembly is slidably connected to the intake cylinder via a floating column, allowing it to float up and down with the waves. The bottom of the floating column is connected to a base and uses a floating elastic element to buffer impacts, enabling the entire mechanism to adapt to changes in sea surface fluctuations. The floating column simultaneously drives the outer and inner thorny wheels to rotate. The outer thorny wheel drives an anti-clogging wheel via a transmission belt, preventing algae and other impurities from clogging the inlet.

The control motor is securely connected to the secondary pretreatment component to ensure structural stability. Feedback springs are securely connected to both the flow valve and the control piston, providing real-time feedback on water flow fluctuations and automatically adjusting the control piston position, forming a closed-loop regulating structure. This ensures stable and precise water flow, preventing damage or efficiency reduction of the membrane module due to unstable water flow, and effectively guaranteeing the efficient and stable operation of the entire desalination process.

The permeate inner tube is tightly connected to the switching assembly, and the sliding of the switching block enables rapid switching of the permeate flow path during reverse osmosis. The switching hydraulic cylinder is tightly connected to the regulating pipe, and the hydraulic cylinder drives the switching block to slide precisely along the regulating pipe, achieving precise flow control of the permeate. The abutting electromagnetic block abuts against the switching block and is connected to the control valve through magnetic pole attraction. When the control valve moves, it drives the abutting electromagnetic block, and the abutting elastic element ensures a continuous and stable abutting state between the electromagnetic block and the switching block, making the switching action more precise and reliable. The control valve is slidably connected to the regulating pipe, and the elastic restoring force applied by the control elastic element ensures that the control valve is always in the appropriate position, guaranteeing rapid and stable opening and closing of the permeation channel. The regulating pipeline features a spiral channel. When connected to the transfer pump, seawater flowing through this spiral channel generates turbulence, effectively reducing membrane surface fouling, improving the hydrodynamic characteristics of the reverse osmosis membrane surface, and increasing water flux and desalination efficiency. Simultaneously, the conductivity sensor is securely connected to the regulating pipeline, monitoring water conductivity in real time and providing timely data feedback for adjusting osmosis process parameters, ensuring stable desalinated water quality.
