Spiral heat exchanger 220 m2, AISI 304

Spiral heat exchangers are widely used in various industries due to their advantages over other types of heat exchangers. Spiral heat exchangers are used as condensers, evaporators, as well as for cooling and heating liquids, gases and gas-vapor mixtures. Rectification columns can be arranged by spiral heat exchangers as dephlegmators. Spiral heat exchangers are particularly effective for processing high-viscosity liquids, since the problem of distributing such liquid through pipes is eliminated, as well as when processing slurries and liquids containing fibrous materials and inclusions. ADVANTAGES OF A SPIRAL HEAT EXCHANGER - the possibility of using spiral heat exchangers with "problematic" media, such as highly polluted liquids, aggressive and very viscous media, etc.; - high efficiency of spiral heat exchangers over the entire load range; - low pressure loss through the channels of spiral heat exchangers; Compactness of the spiral heat exchanger, thus saving useful space - easy cleaning of spiral heat exchangers of deposits by mechanical or chemical washing methods; - wide range of flow types and channel types in spiral heat exchangers; - reducing the operating costs of spiral heat exchangers for stops, since cleaning is carried out much less frequently and easier than other types of heat exchangers, shell-and-tube, plate and others; - 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 the production of alcohol from starch-containing raw materials uses the following technological cycle: - 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 proven themselves very well instead of built-in coils in fermentation tanks (built-in coils-heat exchangers inside the fermentation tank) are poorly washed due to the design features of the placement and therefore leads to microbiological contamination of the Braga. 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 have also proven themselves in recycling water supply systems using natural sources that act as a refrigerant. Spiral heat exchangers or spiral heat exchanger stands 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. 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.
