The production process of deionized water machine for solar photovoltaic silicon chip washing and drying machine involves multiple aspects such as equipment design, material selection, system configuration, process parameter control, and safety maintenance. The following is a detailed introduction:
1、 Equipment Design
Appearance and Structure:
The external dimensions of the device host are usually 650mm wide (left and right), 550mm thick (front and back), and 1280mm high, which can be adjusted according to actual needs.
The equipment adopts standardized or personalized water production processes for water production, with low operating costs and high equipment reliability.
System configuration:
Equipped with high-precision resistivity, pressure, flow rate, and pipe diameter monitoring systems to ensure that water quality meets the requirements of standards such as SEMITOL, Verteq, and Beijing 45th Institute.
Using stainless steel, PFA high-purity pipe fittings, and corrosion-resistant materials such as polytetrafluoroethylene to ensure the purity of water quality.
2、 Material selection
Filter material:
Select efficient filtration materials such as reverse osmosis membranes, ion exchange resins, etc. to remove impurities such as ions, organic matter, and microorganisms from water.
The filtering material needs to be replaced regularly to ensure the filtering effect.
Pipes and fittings:
The pipes and joints are made of corrosion-resistant materials such as stainless steel and PFA high-purity fittings to prevent water pollution during transmission.
The pipeline connection should be tight to prevent water leakage.
3、 System configuration and process parameter control
Preprocessing system:
Including steps such as sand filtration and carbon filtration, it removes suspended solids, residual chlorine, and other impurities from the water, providing stable water quality conditions for subsequent treatment.
The pre-treatment system needs to be backwashed and filter media replaced regularly to maintain its treatment effect.
Reverse osmosis system:
By utilizing the selective permeability of reverse osmosis membranes, most ions and organic matter in water can be removed, resulting in relatively pure water.
The reverse osmosis system requires regular cleaning and replacement of the reverse osmosis membrane to prevent membrane fouling and blockage.
Ion exchange system:
By using ion exchange resin to further remove ions from water, the electrical resistivity of the water is increased.
Ion exchange resins need to be regularly regenerated and replaced to maintain their exchange capacity.
Terminal filtering system:
Using terminal filtration materials such as microporous membranes to remove small particles and microorganisms from water, ensuring the purity of water quality.
The terminal filtration system needs to regularly replace the filter membrane to prevent membrane blockage and contamination.
Process parameter control:
Strictly control the process parameters of each processing unit, such as pressure, flow rate, recovery rate, etc. of the reverse osmosis system, as well as the flow rate and regeneration cycle of the ion exchange system.
Regularly test and analyze water quality, adjust process parameters based on test results, and ensure stable and compliant water quality.
4、 Safety and Maintenance
Safety measures:
The equipment is equipped with safety devices such as leakage protection and overload protection to ensure the safety of operators.
During the operation of the equipment, operators need to wear protective equipment such as goggles and gloves to prevent water from splashing onto the skin and eyes.
Maintenance and upkeep:
Regularly maintain the equipment, such as cleaning filter materials, replacing filter membranes, checking pipeline connections, etc., to ensure the normal operation of the equipment.
Establish equipment archives to record the operation status, maintenance, and other information of the equipment, providing a basis for the subsequent management of the equipment.
