Heat exchange apparatus and pulp making system

Abstract

The utility model discloses a kind of heat exchange equipment and pulping system. Heat exchange equipment includes heat exchange cylinder and cold pipe. Heat exchange cylinder is provided with heat exchange cavity, feed inlet and discharge port, heat exchange cavity is communicated with feed inlet and discharge port, cold pipe is set in heat exchange cavity, and it is used for being contacted with slurry, cold pipe includes at least one coil pipe, each coil pipe is spirally arranged along the central axis of heat exchange cylinder, each coil pipe includes multiple radiating sections, multiple radiating sections are sequentially connected along the axial direction of heat exchange cylinder, in the axial section of the central axis of heat exchange cylinder, two adjacent radiating sections are spaced apart. Using the heat exchange equipment provided by the utility model, the resistance in the flow process of slurry is reduced, the pressure drop of heat exchange equipment is reduced, the energy consumption of heat exchange equipment is reduced, the pipeline wear and tear and leakage risk caused by high pressure of heat exchange equipment are reduced, the service life of heat exchange equipment is prolonged, the maintenance cost is reduced, and the heat exchange area between slurry and cold pipe is increased, the heat dissipation effect of slurry is improved.
