The accompanying drawing explanation
Fig. 1 is operation principle block diagram of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is operation principle block diagram of the present utility model, as shown in Figure 1, thermal flue gas reclaims circulation energy-saving system, mainly gas fired-boiler, smoke discharging pipe, heat recovering heat exchanger, frequency conversion smoking blower fan, water cooling pond, heat storage water tank, air source hot pump water heater etc., consists of; Described smoke discharging pipe is provided with several intake interfaces, position, the gas outlet frequency conversion smoking blower and pipeline that frequency conversion smoking blower fan is arranged on smoke discharging pipe is connected to the oil smoke pond, be provided with wind transducer in smoke discharging pipe to control the rotating speed of frequency conversion smoking blower fan, when the speed of the inner wind of smoke discharging pipe flows through hour, the rotating speed that suitably promotes frequency conversion smoking blower fan is placed the situation of smoking and stagnating that occurs.Described smoke discharging pipe/water-to-water heat exchanger gentle with heat recovery heat exchange device respectively is connected, and gas/water-to-water heat exchanger is by pipeline and air source hot pump water heater UNICOM, the hot water outlet of this air source hot pump water heater and heat storage water tank UNICOM.
Heat recovery heat exchange device is respectively by pipeline and water cooling pond and heat storage water tank UNICOM.Wherein between water cooling pond and recovery heat-exchanger rig, be provided with suction pump, ratio water inlet device, wherein suction pump is for the cold water suction in water cooling pond is reclaimed in heat-exchanger rig, and the ratio water inlet device enters for regulating cold water the flow that reclaims heat-exchanger rig.Be provided with attemperating unit between heat storage water tank and heat recovery heat exchange device, also be provided with water supplement port, water return outlet and hot water outlet on this heat storage water tank.
Specific implementation process is as follows:
The above oil smoke of temperature altitude 85 degree of the discharge of induced-draft fan enters smoke discharging pipe through pipeline from the intake interface of smoke discharging pipe, the temperature of smoke discharging pipe inside reaches rapid rising, open suction pump, cold water is drawn into to heat recovery heat exchange device from water cooling pond, and the attemperating unit that is arranged on the interlock temperature outlet valve between heat recovery heat exchange device and heat storage water tank sets temperature value in advance.The size of the temperature value of setting according to interlock temperature outlet valve, the passing ratio water inlet device is regulated the flow that cold water flows into water circulating pipe, the temperature value of setting when interlock temperature outlet valve larger, suitably turn down the cold water influx, to reduce water velocity, increase heat exchanger time, otherwise, suitably tune up the cold water influx.
