Selection of spiral plate heat exchanger equipment
When selecting spiral plate heat exchanger equipment, Murphy experts suggest that users should specify the general requirements for heat exchangers, including the specific requirements for the selection of spiral plate heat exchanger equipment should have thermal performance, including the flow of fluid on each side, inlet and outlet temperature, heat transfer, etc. Attention should also be paid to the type of fluid and the fluid's thermophysical properties, physical and chemical properties (such as fouling, corrosion, danger, and impurities, etc.).
Clarify the operating conditions, working pressure and environmental conditions of spiral plate heat exchanger equipment; Next, it is necessary to pay attention to the clear technical and economic requirements, such as heat exchanger material, price, weight, size, flow resistance and fan and pump power, operating life, maintenance and cleaning requirements, maintenance cycle, transportation and installation restrictions.
Spiral plate heat exchanger equipment in the second step of selection, should be clear about the main characteristics of various forms of heat exchangers, to pay attention to the performance of various heat exchangers, characteristics, the scope of use to summarize and compare, for some specific cases to be considered, such as considering the relationship between various characteristics and specific requirements, the source of materials and the level of designers, manufacturers, operators, etc.
The third step of the selection of spiral plate heat exchanger equipment, the selection of heat exchanger should also consider the flow form of the fluid; Notice the type of fluid; For the heat exchanger equipment weight and size restrictions should also pay attention to; Restrictions on invested costs and operating costs should also be considered; The difficulty of fouling and cleaning is also considered.
In conclusion, about the use of spiral plate heat exchanger equipment, pay attention to check whether the pressure gauge, level gauge, thermometer and related valves are safe and sound; In the production should be first into the cold fluid, and then slowly into the hot fluid, to do the first preheat and then heating, avoid sudden cold sudden heat, so as not to damage the heat exchanger, causing losses; Pay attention to frequently analyze and check the composition, temperature and pressure of the two fluids to determine whether there is any internal leakage for timely treatment.
