Uses:
1. The spiral - plate heat exchanger used in chemical, petroleum, medicine, food, solvent, light industry, textile, metallurgy, steel rolling, such as coking industry.
2. A suitable steam faw, steam fluid and a liquid convection heat transfer, waste heat recovery, can also be used for steam condensation and evaporation heat transfer fluids.

Structure and features:
1. This equipment is composed of two pieces of steel plate, formed two uniform spiral channel, two heat transfer medium can reverse flow, greatly enhance the heat transfer effect, even if the two small medium temperature, also can achieve the ideal heat transfer effect.
2. Take on the shell structure of tangential, local resistance is small, uniform due to the curvature of the helical channel, the fluid flow within the device to no big reversing, the total resistance is small, so that can improve the design flow rate of high heat transfer capability.
3. Ⅰ not detachable type spiral skill type heat exchanger of helical channel transverse welding seal, thus has high sealing
4. Ⅱ, Ⅲ detachable spiral - plate heat exchanger structure principle and not detachable type heat exchanger basic same, Ⅱ type two channels with detachable cleaning, Ⅲ type has a channel with detachable cleaning, especially for precipitation of liquid viscosity, heat exchange, wide application scope.
5. Spiral - plate heat exchanger of the nominal pressure PN0.6, 1.0, 1.6, 2.5 Mpa (refers to the channel under the maximum working pressure), according to the material can be divided into carbon steel and stainless steel. Single equipment cannot satisfy the use requirement, with more than one combination. (parallel combination, series combination, hybrid combination) user could be selected according to the practical process.
