Summary of the invention:
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of and can reach refrigerating gas when operation, can extract the shell and tube air heat exchanger that utilizes waste heat of heat energy output hot water again.
The purpose of this utility model is achieved in that a kind of shell and tube two-stage air heat exchanger that utilizes waste heat, comprise cylindrical shell, on, low head, heat-exchanging tube bundle, advance, gas outlet and cooling water advance, outlet, heat-exchanging tube bundle is axial arranged in cylindrical shell, advance, the gas outlet is connected on the barrel wall, be characterized in that cylindrical shell middle part diameter is greater than last, following diameter, the middle part radially is provided with in the cylindrical shell, under cut apart assembly, on, under cut apart assembly heat-exchanging tube bundle axially be divided into, two restraint down, last heat-exchanging tube bundle lower end and following heat-exchanging tube bundle upper end are respectively with last, under to cut apart assembly fixedly connected, on, following heat-exchanging tube bundle air communication, the low head both sides connect remaining hot water and advance, outlet, cooling water advances, outlet is connected in the upper cover both sides, connect the waste heat water valve on the waste heat mouth of a river, cooling water inlet is connected cooling water valve with exporting, be communicated with water inlet pipe between the outlet of the cooling water valve import of cooling water inlet side and remaining hot water, be communicated with outlet pipe between remaining hot water import and the coolant outlet, connect water intaking valve on the water inlet pipe, connect outlet valve on the outlet pipe.
Last heat-exchanging tube bundle is used for the required temperature of equipment process for cooling in service, and following heat-exchanging tube bundle is used to provide heating hot water.Valve state when needing heat supply water in the winter time is, the valve open of cooling water import and export, the valve closing on the inlet tube and outlet tube, and remaining hot water enters from the remaining hot water import, flows out from the valve of remaining hot water outlet.Valve state when need improve cooling effect summer is: the cooling water inlet valve is opened half, the valve open on the inlet tube and outlet tube, and remaining hot water import and export valve closing, this moment, two heat-exchanging tube bundles were done the cooling operation simultaneously up and down.
The utility model is under the prerequisite that does not change former heat exchanger installation dimension, change a heat-exchanging tube bundle into two heat-exchanging tube bundles, and outside cylindrical shell, set up the valve pipe intercommunication, can be according to the arts demand flexible modulation, thereby both reached the technological requirement that has solved refrigerating gas, and extracted heat energy again and produced hot water.
