Carbon steel spiral plate heat exchangers are mainly used in the following fields:
1. Petrochemical industry: used for preheating crude oil, condensing steam at the top of distillation tower, cooling residual oil at the bottom of vacuum tower, etc. in the process of petroleum refining; In chemical production, it can be used for heat exchange in various chemical reaction processes, such as cooling of shift gas in synthetic ammonia production, heating and cooling of methylammonium solution in urea production, heat recovery of sulfur dioxide converter in sulfuric acid production, etc. It can also be used for heating, cooling, evaporation and condensation of chemical raw materials and products.
2. Refrigeration industry: It can be used as a condenser to cool and condense the high-temperature and high-pressure refrigerant vapor discharged from the refrigeration compressor into liquid; It can also be used as an evaporator to evaporate and absorb heat from low-temperature and low-pressure refrigerant liquid, achieving refrigeration effect. It is commonly used in chillers, cold storage, air conditioning systems, etc.
3. Food processing industry: used for processes such as sterilization, cooling, and heating of food. For example, in the production of beverages such as milk and juice, the materials are cooled after pasteurization or high-temperature instantaneous sterilization; Heating or cooling animal and vegetable oils in oil processing; In meat processing, operations such as cooling or thawing are performed on meat products.
4. Pharmaceutical industry: In the pharmaceutical process, it is used for heating or cooling of drug synthesis reactions, concentration and distillation of drug solutions, freeze-drying of drugs, and can also be used for circulating cooling water systems in pharmaceutical equipment to cool down the equipment.
5. Environmental protection industry: In wastewater treatment, it can be used for heat exchange between wastewater and wastewater, as well as between wastewater and clean water, to achieve heat recovery and improve energy utilization efficiency; It can also be used for heat control in processes such as sludge dewatering in wastewater treatment.
6. Metallurgical industry: used for heating or cooling aluminum salt mother liquor, cooling molten steel in steelmaking processes, cooling continuous casting billets, cooling emulsions in steel rolling workshops, cooling and purifying blast furnace gas, etc. It can effectively recover waste heat in metallurgical processes and reduce energy consumption.
7. Paper industry: Used for heating pulp in the papermaking process, cooling cooking liquids, heat recovery in bleaching processes, heating and washing pulp, etc., which helps to improve the efficiency and quality of papermaking processes and save energy.
8. Power industry: It can be used for cooling high-voltage transformer oil, cooling generator bearing oil, heating condensate water in thermal power plants, cooling circulating water, etc., to ensure the normal operation of power equipment and improve power generation efficiency.
9. HVAC industry: In centralized heating systems, waste heat from thermal power plants is used as a heat exchanger for district heating, providing heating for buildings; In air conditioning systems, condensers and evaporators are used in the refrigeration cycle to cool and heat the air.
10. Mechanical industry: used for cooling various quenching fluids, lubricating oil for reducers, hydraulic oil, etc., to ensure that the components of mechanical equipment work at appropriate temperatures, improve equipment reliability and service life.
