The quartz sand acid washing production line is a core complete set of
equipment for high-purity quartz sand production, widely used in high-end fields
such as photovoltaics, electronics, glass, etc. The entire production line
covers core processes such as raw material pretreatment, acid washing reaction,
water washing neutralization, dehydration drying, etc. The core is suitable for
acid washing reaction kettle, calcination furnace, CTB permanent magnet drum wet
magnetic separator, DTS vibration dehydration screen and other equipment. The
impurity content of the finished quartz sand is required to be ≤ 0.05%, there is
no acid residue, the production process meets environmental standards, the
equipment has no serious corrosion, and its impurity removal accuracy and
equipment stability directly determine the quality of the finished sand and the
service life of the production line. In actual production, enterprises often
face problems such as incomplete acid washing and impurity removal, equipment
corrosion and leakage, rapid consumption of acid solution, and substandard
wastewater discharge, which restrict product upgrades and increase maintenance
and environmental protection costs.
As a technology-based enterprise specializing in the research and
development, manufacturing, and service of complete sets of quartz sand
equipment, Shanlu Heavy Industry has been deeply rooted in the industry for more
than ten years. It has a standardized production base, professional R&D and
technical service team, and can provide customized design, equipment selection,
acid washing process optimization, installation and commissioning, operation and
maintenance training, and full process technical support for quartz sand acid
washing production lines. It covers the customization, adaptation, and spare
parts supply of core equipment such as acid washing reaction vessels and
calcination furnaces. All products and solutions strictly comply with industry
safety, environmental protection, and high-purity quartz sand production
standards. It has provided acid washing production line solutions for dozens of
enterprises across the country, helping enterprises solve pain points such as
impurity removal and corrosion, and achieve compliant and efficient
production.
Based on the core pain points of the quartz sand pickling production line and
practical on-site experience, Shanlu Heavy Industry has developed a compliant,
pragmatic, and directly implementable optimization plan, which is professional,
rigorous, and without any exaggeration:
1. Incomplete acid washing and impurity removal: The core causes are improper
acid solution ratio, insufficient acid washing time, uneven stirring, and
inadequate adaptation of impurity removal equipment. Optimization plan: Based on
the types of impurities in quartz sand (such as iron, aluminum, calcium, etc.),
accurately ratio the concentration of acid solution. Shanlu Heavy Industry can
provide professional acid solution ratio guidance to ensure that impurities are
fully reacted; Optimize the operating parameters of the acid washing reaction
kettle, set the acid washing temperature and time reasonably, and equip it with
a variable frequency stirring device to ensure sufficient contact between quartz
sand and acid solution, eliminating stirring dead corners; Paired with CTB
permanent magnet drum wet magnetic separator and LHC vertical ring high gradient
magnetic separator, the residual magnetic impurities after acid washing are
removed for the second time, improving the accuracy of impurity removal.
2. Equipment corrosion and leakage: mainly caused by unsuitable equipment
materials, acid corrosion, aging of anti-corrosion coatings, and substandard
welding processes. Optimization measures: Core equipment such as acid and alkali
resistant fiberglass or polytetrafluoroethylene lining materials are selected
for acid pickling reaction vessels and pipelines to enhance anti-corrosion
performance. Shandong Heavy Industry can provide customized anti-corrosion
equipment; Regularly inspect the anti-corrosion coating of equipment, promptly
repair any damages found, and avoid acid leakage; Adopting seamless welding
technology to improve equipment sealing, equipped with corrosion-resistant
sealing components to eliminate the hidden danger of acid leakage and ensure
production safety.
3. Rapid consumption of acid solution and non compliant wastewater discharge:
often caused by rapid evaporation of acid solution and inadequate adaptation of
wastewater treatment equipment. Disposal plan: Install a sealing cover on the
acid pickling reaction kettle to reduce acid evaporation, and equip it with an
acid recovery device to achieve acid recycling and reduce consumption; Based on
the amount of acid washing wastewater and the concentration of pollutants, the
BK high-pressure diaphragm plate frame filter press and NM thickener are
accurately matched to filter and neutralize the acid washing wastewater,
ensuring that the wastewater meets the discharge standards and environmental
regulations; Optimize the water washing and neutralization process, reduce the
consumption of clean water, and lower the pressure of wastewater treatment.
In terms of daily operation and maintenance, Shanlu Heavy Industry provides
professional guidance: conduct daily inspections of the operation status,
impurity removal effect, acid concentration, and wastewater discharge of all
equipment on the entire production line, and keep detailed records; Clean the
acid pickling reaction kettle and residual acid and impurities in the pipeline
every week, and check the anti-corrosion coating and sealing condition of the
equipment; Calibrate process parameters such as acid solution ratio and pickling
time every month, tighten loose parts, and replenish equipment lubricating
grease; Conduct comprehensive maintenance on the production line every quarter,
replace aging anti-corrosion coatings, seals, and worn parts, conduct operation
and maintenance training to ensure long-term stable and compliant operation of
the production line.
