Stainless steel spiral plate heat exchangers are widely used in various industries with high requirements for heat transfer efficiency and medium adaptability, thanks to the corrosion resistance of stainless steel material, the efficient heat transfer capacity of the spiral structure (good turbulence effect, high heat transfer coefficient), as well as the advantages of compact structure and non clogging. The specific details are as follows:
1、 Chemical industry
The heating, cooling, or condensation processes involving a large amount of corrosive media such as acids, bases, and organic solvents in chemical production make stainless steel spiral plate heat exchangers core equipment due to their corrosion resistance (especially 316L and other models' resistance to strong acids and bases) and efficient heat transfer characteristics
Application scenarios: preheating/cooling of materials in synthesis reactions, condensation processes in solvent recovery (such as distillation condensation of organic solvents such as ethanol and acetone), heating of acid-base solutions (such as cooling during sulfuric acid dilution), constant temperature control of catalysts, etc.
Advantages: The turbulence effect of the spiral structure can reduce the retention of the medium on the heat exchange surface, lower the risk of scaling, and is suitable for processing chemical materials containing small amounts of impurities.
2、 Pharmaceutical and Bioengineering Industry
Pharmaceutical and biotechnology industries have high requirements for equipment cleanliness, corrosion resistance, and hygiene standards. Stainless steel (especially food grade 304 and 316) materials comply with GMP (Good Manufacturing Practice) requirements, and the structure of spiral plate heat exchangers is easy to clean and disinfect
Application scenarios: Heating or cooling of medicinal liquids (such as constant temperature cultivation in vaccine production), condensation heat exchange in distilled water preparation, temperature control of fermentation tanks (such as cooling during antibiotic fermentation), concentration preheating of traditional Chinese medicine extracts, etc.
Advantages: Smooth surface, no dead corners, residual impurities can be removed through steam sterilization or chemical cleaning to avoid cross contamination, and efficient heat exchange can control temperature to ensure drug activity.
3、 Food and Beverage Industry
In the production of food and beverage, it is necessary to handle perishable or sugar containing media such as fruit juice, dairy products, beer, etc. The equipment should be corrosion-resistant, easy to clean, and able to quickly heat, cool, or sterilize the materials
Application scenarios: Pasteurization of fruit juice and jam (rapid cooling after heating to a specific temperature), preheating and cooling of milk (to avoid protein denaturation), heating/cooling of malt extract in beer brewing, heating and dissolving of syrup in beverage production lines, etc.
Advantages: Stainless steel has a smooth surface that does not adsorb materials and is not prone to bacterial growth. The high heat transfer efficiency of the spiral structure can shorten the heating time of materials, reduce nutrient loss or flavor changes.
4、 Metallurgical and metal processing industry
A large amount of oil and acid containing cooling wastewater will be generated in the metallurgical process, or temperature control of high-temperature materials (such as steel rolling lotion and quenching oil) is required. The stainless steel spiral plate heat exchanger can adapt to such oil containing and slightly corrosive media:
Application scenarios: cooling of emulsion during steel rolling (maintaining the stability of lotion and avoiding oil deterioration due to high temperature), cooling of acid solution after metal pickling (such as cooling recovery of hydrochloric acid and nitric acid solution), circulating cooling of quenching oil (controlling quenching temperature to ensure metal hardness).
Advantages: Strong impact resistance, able to adapt to fluctuations in medium flow rate and temperature in the metallurgical industry, and the spiral structure is not easily blocked by small particles such as iron filings in emulsions.
5、 Food processing and brewing industry
In addition to pharmaceutical grade high demand scenarios, stainless steel spiral plate heat exchangers are also widely used in ordinary food processing (such as seasoning, beverage, and alcohol brewing), mainly for temperature regulation and energy recovery of materials:
Application scenarios: sterilization and cooling of soy sauce, vinegar and other fermented liquids, cooling of fruit juice in wine making (to prevent oxidation), cooling of cold wort after beer fermentation, pasteurization and cooling of dairy products (such as yogurt).
Advantages: Compact structure, small footprint, suitable for limited workshop space in food factories; At the same time, stainless steel material will not undergo chemical reactions with food, ensuring product purity.
6、 Environmental Protection and Sewage Treatment Industry
In the field of environmental protection, the treatment of industrial wastewater and domestic sewage often involves temperature regulation (such as preheating the wastewater and entering the biochemical tank to improve reaction efficiency, or cooling the treated effluent). Stainless steel spiral plate heat exchangers can adapt to the small amounts of acidity, alkalinity, organic matter, and other components that may be contained in the wastewater
Application scenarios: Waste heat recovery of industrial wastewater (such as transferring heat from high-temperature wastewater to low-temperature influent), heating/cooling of leachate from garbage (maintaining appropriate temperature for biochemical treatment), and cooling of slurry in flue gas desulfurization systems.
