Spiral heat exchanger 20m2 steel 304

spiral heat exchangers for the chemical industry, utilities, food industry Spiral heat exchangers are used as condensers, evaporators, as well as for cooling and heating liquids, gases and gas-vapor mixtures. The possibility of using spiral heat exchangers with "problematic" media, such as highly polluted liquids, aggressive and very viscous media, etc. The removed spiral heat exchanger for wash cooling is well washed. When washing the fermentation tank, water is also pumped through a spiral heat exchanger.Spiral heat exchangers for the food industry Spiral heat exchangers for the food industry spiral heat exchangers are suitable for cooling vegetable oils, suspensions, ingredients with the inclusion of dry substances, grain particles, malt, etc. Spiral heat exchangers for distilleries. At the distillery, a bioethanol plant where alcohol is produced from starch-containing raw materials, the following technological cycle is used: - preparation, cleaning and crushing of grain. - mixing with hot water that comes out of the spiral heat exchanger heated to a temperature of 80-90 degrees . The water is heated on a spiral heat exchanger, in technology it is called a recuperative spiral heat exchanger of the cooking compartment . - spiral heat exchanger for cooling the wort after GDFO (hydro-enzymatic treatment) cooling the wort with the inclusion of 20-25% of dry substances from a temperature of 90 ° C to a temperature of 60 ° C (in the case of using a saccharifier) or to a temperature of 32-35 ° C (in schemes that do not use a saccharifier in the technology). Spiral heat exchangers have also proven themselves in recycling water supply systems using natural sources that act as a refrigerant. Spiral heat exchangers on the primary circuit-pond, river, storage ... the Spiral heat exchanger is not afraid of BIOLOGICAL and MECHANICAL contamination in the recycled water, which can be caused by deposits. Heat exchangers with a removable cover are easily cleaned from dirt and can be used for heat carriers with solid inclusions or biological deposits, thereby clogging the flow, as in plate heat exchangers. Heat exchangers with a removable cover are easily cleaned from dirt and can be used for heat carriers with solid inclusions. Structural features of manufacturing spiral heat exchangers. Structural features of manufacturing spiral heat exchangers. In order to strengthen the design of the spiral heat exchanger, spacers are used between the sheets of the spiral heat exchanger-pins. The pins between the sheets of the spiral heat exchanger are made of a material similar to that of the sheet of spiral heat exchangers. Fix the pins by welding to the sheet of the spiral heat exchanger. spacers between the sheets of the spiral heat exchanger-pins Spiral heat exchangers have a number of advantages over other types: plate heat exchanger, shell-and-tube heat exchanger. The main advantage is the ability to use spiral heat exchangers for pumping liquids and mixtures that include solid particles commensurate with the height between the turns of the spiral. If, for example, the height between the sheets of a spiral heat exchanger is 14 mm, then the size of inclusions in the liquid may well reach 10-12 mm.
