Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is done further to describe in detail:
Fig. 1 is structural representation of the present utility model.
In figure: 11, primary purifying device; 12, secondary stage purified device; 2, heat exchanger; 21, wastewater inlet pipe; 22, wastewater effluent pipe; 23, clear water water inlet pipe; 24, Graceful water pipe; 25, stop valve; 26, blow-off pipe; 27, blowoff valve; 28, waste water shut off valve; 29, steam input pipe; 30, steam valve; 31, clear water arm; 32, clear water shut off valve; 33, arm shut off valve; 34, suspended body flowmeter.
The specific embodiment
As shown in Figure 1, the present embodiment discloses a kind of destarch, mercerising waste-heat recovery device, it reclaims the waste heat in the waste water producing in destarch, waste heat process, this device comprises waste water purification device and the heat exchanger 2 being connected with this waste water purification device, waste water purification device carries out necessary filtration to waste water, the content that reduces impurity wherein, the waste heat of 2 pairs of waste water of heat exchanger reclaims.The secondary purification device that waste water purification device is comprised of primary purifying device 11 and secondary stage purified device 12.On heat exchanger 2, be provided with the wastewater inlet pipe 21 that is connected with waste water purification device, discharge waste water wastewater effluent pipe 22, carry out the clear water water inlet pipe 23 that the clear water of heat exchange flows into and the Graceful water pipe 24 flowing out for clear water with waste water.Waste water enters into heat exchanger 2 inside from wastewater inlet pipe 21, by wastewater effluent pipe 22, flowed out again, clear water enters into the inside of heat exchanger 2 from clear water water inlet pipe 23, by Graceful water pipe 24, flowed out again, in this process, waste heat in waste water is taken away by clean clear water, makes the temperature of waste water drop to 35 degrees Celsius of left and right by 80 degrees Celsius of left and right.
Although there is waste water purification device to filter waste water, the impurity of protecting in waste water can not be filtered completely, and the impurity of sneaking in heat exchanger 2 will have part to be deposited in the pipeline in heat exchanger 2.The destarch of the present embodiment, mercerising waste-heat recovery device can clean by the impurity to precipitation easily and effectively, have guaranteed the long-play of heat exchanger 2.In the present embodiment, on wastewater inlet pipe 21, be provided with this heat exchanger 2 and waste water purification device are closed to the stop valve 25 being connected, on wastewater effluent pipe 22, be provided with waste water shut off valve 28, on the wastewater inlet pipe 21 between stop valve 25 and heat exchanger 2, be connected with a blow-off pipe 26, on the wastewater effluent pipe 22 between waste water shut off valve 28 and heat exchanger 2, be connected with a steam input pipe 29, on blow-off pipe 26, be provided with blowoff valve 27, on steam input pipe 29, be provided with steam valve 30.
When stop valve 25 and waste water shut off valve 28 are closed, open blowoff valve 27 and steam valve 30, will in wastewater effluent valve 22, pass into steam, it can blow out the impurity in heat exchanger 2, makes it have blow-off pipe 26 to discharge.
