Detachable Spiral Plate Heat Exchanger introduction
Spiral-plate heat exchanger is a kind of high efficiency heat exchanger device which is applicable to vapor-vapor, vapor - liquid, liquid – liquid heat transfer to liquid. It is suitable for chemical, oil, solvents, pharmaceutical, food, light industry, textile, metallurgy, steel rolling, coking and other industries. It can be divided into non-detachable type (Ⅰ) and detachable type (Ⅱ, Ⅲ) spiral plate heat exchangers according to the structural form.
Structural principle and non-removable heat exchangers are basically the same, but the channel can be opened and cleaned, sealed at both ends plus head. Particularly suitable for the exchange of liquid with viscous and precipitated liquid, as well as gas - liquid and steam condensate.
As the removable heat exchanger needs to add head, flange and other components, the cost of equipment is slightly larger than the non-removable heat exchanger.
1.Manual electrical arc welding
2.Manual argon arc welding
3.Automatic hidden arc welding
4.CO2 gas protective welding
5.Tube plate full position arc welding
1, This equipment is suitable for liquid - liquid, gas-gas, gas - liquid convection heat transfer which can be used for vapor condensation and liquid evaporation heat transfer. Therefore it is applicable in chemical industry, petroleum, medicine, machinery, electric power, light industry and textile industries, etc.
2, This equipment is composed of two pieces of steel plates to form two uniform spiral channels. Two heat transfer cut-off ways may realize fully reversed flow ,which is applicable for heat transfer with small temperature differential. Therefore it is easy for low temperature heat source recycling and accurate outlet temperature control.
3,The connection pipe on the shell is of tangential structure with small partial resistance. The curvature of spiral channel is even and the fluid has no large direction change inside the equipment. Therefore the total resistance is small, which may increase design flow speed and realize higher heat transfer ability.
4. The end surface of spiral channel is sealed because of welding so the sealing performance is good with reliable structure.
