Spiral Blatt Wärmetauscher

This is a high efficient heat exchanging equipment, including grade I, II and III. It is made of carbon steel, stainless steel or mixture of the above mentioned materials. It is available for gas-gas, liquid-liquid, and gas-liquid convective heat transfer, in addition to the steam condensing and liquid evaporation heat transfer. Hence, this product is widely used in heat energy transfer and waste heat recycle for the pharmaceutical, chemical, rosin, dye and foodstuff industries.This product features high heat transfer efficiency, strong dirt cleaning capability, good energy conservation, low price and reliable use.Structure and performances:1) This product is made of two rolls, which form two even spiral channels.The two heat transfer medium can have full adverse current flow, whichcan greatly strengthen the heat transfer results. Even for two media withlittle temperature difference, it can also achieve ideal heat transfer results2) The connected pipe on the shell adopts the tangential structure, withlittle partial resistance. Since the curvature of the spiral channel is evenand the liquid does not have large turning when flowing in the equipment,with little total resistance, so that it can raise the designed flow speedwith higher heat transfer capability3) Spiral channel surface of grade I in-dismountable spiral sheet heatexchanger adopts welded seal, with relatively high airtight performance.4) The structural principle of grade II dismountable spiral sheet heatexchanger is basically as the same of the in-dismountable heatexchanger; however, one of its channels can be dismantled for cleaning.It is especially applicable to the heat transfer of liquid with stickiness andsediment5) The structural principle of grade III dismountable spiral sheet heatexchanger is basically same as the in-dismountable heat exchanger;however, one of its channels can be dismantled for cleaning6) Spiral sheet heat exchanger has the nominal pressure of PN0.6, 1.0,1.6 and 2.5MPa (the largest working pressure the single channel canbear). It is made of carbon steel or stainless steel, and it can be designedand manufactured according to the actual technical needs of customers7) If one set of equipment fails to satisfy the use requirements, then severalsets can be combined for use. However, it must conform to the followingregulations: the distance between the equipment and channel for parallelconnection and series connection must be identical. Mixed connection isneeded: one channel for parallel connection and the other for seriesconnection
