Pickling circulation
- This pump is used as a circulating pump for cleaning and removing oxides on the surface of metal products with acidic solutions.
- Application examples: Circulation and temperature raising pumps for acidic solutions, agitation pumps, spray atomizers, waste acid transfer pumps, etc.
Waste acid transfer,
- Waste acid used in pickling, etc. is transferred.
- FRP corrosion-resistant pumps are often used because they are acidic solutions and contain a lot of scale and impurities.
- Application example: Waste acid transfer pump
Roasting furnace Hydrochloric acid recovery
- This process recovers hydrochloric acid and iron oxide from an aqueous iron chloride solution discharged from the pickling process.
- FRP corrosion-resistant pumps are used for spraying and transferring waste acid in the spray roasting method (Rusner method).
- Application examples: Waste acid transfer pumps, concentration circulation pumps\
Scrubber circulation(Exhaust gas processing)
- Exhaust gas treatment equipment, also called removal equipment or scrubbers, detoxifies various gases used in manufacturing processes and safely discharges them.
- This pump is used to pump circulating liquid when acid gas discharged from the pickling process is cleaned with a scrubber.
- Application example：Washing liquid circulation pump､Washing tower fans, detoxification tower fans, scrubber induction fans, damper for washing tower, damper for detoxifying tower, scrubber induction fan inlet/outlet, etc.
Seawater filtration circulation(aquarium LSS)
- LSS (Life Support System), the heart of the aquarium
- LSS has many FRP corrosion-resistant pumps for various processes such as seawater filtration, transfer, and sterilization.
- In aquariums, FRP corrosion-resistant pumps are often used because metals are prone to pitting corrosion and crevice corrosion caused by seawater
- Application examples: Seawater filtration circulation pumps, seawater transfer pumps, seawater intake pumps, ozone generator booster pumps, etc.
Seawater electrolysis equipment
- Electrolysis equipment produces sodium hypochlorite by direct electrolysis of seawater or salt water to prevent the attachment of microorganisms, shellfish, and other marine organisms.
- It is also used to improve water quality and maintain transparency at power plants, various plants in coastal industrial areas, and aquariums, as well as for sterilization of water supply systems.
- Since electrolysis equipment is prone to electrical corrosion due to stray current, pitting corrosion and crevice corrosion caused by seawater, FRP corrosion-resistant pumps that are free from corrosion are widely used.
- Application examples: Seawater intake pumps, electrolytic solution injection pumps,fan for chlorine gas, suction blower,damper for chlorine gas, suction blower inlet/outlet, emergency shutoff valve, etc.
Regeneration of pure water equipment
- When the ion exchange resin becomes saturated, the cation exchange resin is washed with hydrochloric acid and the anion exchange resin with sodium hydroxide (caustic soda) to regenerate it.
- In addition, a neutralization facility is required to neutralize the acid and alkali in the reclaimed wastewater as ancillary equipment.
- FRP corrosion-resistant pumps are used in wastewater pits with pH fluctuations because of their corrosion resistance to both hydrochloric acid and sodium hydroxide.
- Application example: Acid-alkali waste liquid pit pump
Electrolytic smelting,
- In the electrolytic refining of copper, a crude copper sheet is used as an anode and a pure copper sheet as a cathode in an aqueous copper(II) sulfate solution.
- FRP corrosion-resistant pumps are used to circulate and transfer sulfuric acid and copper sulfate solutions.
- FRP corrosion-resistant pumps are also used for hydrochloric acid circulation in precious metal recovery processes, sulfuric acid in sulfuric acid plants, and scrubber circulation pumps for flue gas desulfurization.
- Application examples: Electrolyte circulation pumps, pickling pumps, electrolyzer station exhaust fans, granulated slag fans, scrubber fans,Damper for electrolyzer station exhaust fan, scrubber fan inlet/outlet, etc.
Salt manufacturing and Chlorination process
- This equipment is used to heat brine to evaporate the water and form salt crystals.
- The salt is crystallized using an evaporative crystal canner called a vacuum method, which takes advantage of the fact that the boiling point also decreases as the atmospheric pressure drops.
- FRP corrosion-resistant pumps, which are free from corrosion, are widely used because they are prone to electrical corrosion, pitting corrosion, and crevice corrosion problems that occur with metals in salt water.
- Application examples: brine transfer pumps, bitter water transfer pumps
Pickling local exhaust.
- It is employed as an exhaust fan for acidic gases generated when metal products are cleaned and removed from oxides adhering to their surfaces with acidic solutions.
- Application examples: local exhaust fans, scrubber induction fans, exhaust gas fans,local switching damper, damper for fan air volume adjustment, emergency shutoff valve, damper for exhaust gas fan.
Flue gas desulfurization equipment
- Flue gas desulfurization equipment is used to remove and purify sulfur dioxide (SO2) generated by combustion flue gas.
- Since combustion gases include acidic gases that corrode when the temperature drops, FRP corrosion-resistant fans are often used.
- Application examples: flue gas desulfurization fans, combustion exhaust gas fans, scrubber fans,ducts for flue gas desulfurization, combustion flue gas fan damper, emergency shutoff valve, scrubber fan inlet/outlet, etc.
Deodorization equipment
- This process removes odors from garbage, odors from sewage and human waste treatment plants, and exhaust gases with various odors from factories.
- Many FRP corrosion-resistant fans are used in inducing its odor and exhaust gases to transfer, suction, local exhaust, and scrubbers.
- Application examples: deodorizing fans, local exhaust fans,damper for deodorizing fan, local exhaust fan air volume adjustment, etc.
