Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of waste-heat recovery device of relieving haperacidity flue gas, as shown in Figure 1, it comprises fuel tank 10, oil pump 20, flue gas heat exchanger 30 and the steam generator 40 arranged successively, the import and export of described oil pump 20 is connected with the cold pipe import 31 of flue gas heat exchanger 30 with the oil-out 11 of fuel tank 10 respectively, and the cold pipe outlet 32 of flue gas heat exchanger 30 is connected with the hot oil inlet 41 of steam generator 40.Mainly adopt water and relieving haperacidity flue gas directly to carry out heat exchange in prior art, such Problems existing is once pipeline leaks, the SO in relieving haperacidity flue gas
2, SO
3will mix with water and generate acid solution, and then corrosion is caused to pipeline, affect production safety, and by comparison, adopt technical scheme disclosed in the utility model effectively can avoid the problems referred to above, even if pipeline leaks, also be the contact of oil and water, or oil and the contact of relieving haperacidity flue gas, therefore to carry out the waste heat recovery of relieving haperacidity flue gas safer, reliable for employing the utility model, and be convenient to the centralized recovery of the waste heat in relieving haperacidity flue gas.During concrete use, that low-temperature oil in fuel tank 10 is pumped in the cold pipe in flue gas heat exchanger 30 by oil pump 20, simultaneously, relieving haperacidity flue gas enters from the air inlet 33 bottom flue gas heat exchanger 30, and discharge from the gas outlet 34 at flue gas heat exchanger 30 top, relieving haperacidity flue gas is carrying out heat exchange by the low-temperature oil in cold pipe during flue gas heat exchanger 30 and in flue gas heat exchanger 30, thus relieving haperacidity fume afterheat is exchanged to low-temperature oil, it is used for production that low-temperature oil transfers heat to water by steam generator 40 again after exchanging heating, so namely achieve the recycling to the heat in relieving haperacidity flue gas.
As further preferred version: the oil feed line 50 of the oil-out 11 of connection fuel tank 10 and the import of oil pump 20 is provided with arm 51, arm 51 exports 42 away from one end of oil feed line 50 with the cold oil of steam generator 40 and is connected, and oil feed line 50 is provided with check valve 60 between arm 51 connectivity part and fuel tank 10, check valve 60 forms the unidirectional general formula blowing of fuel tank 10, as shown in Figure 1, low-temperature oil cold oil outlet 42 from steam generator 40 can discharged by the Oil Guide effect of arm 51 is imported in oil feed line 50 again and recycles, very convenient.
Actually add man-hour, in order to ensure the recovery ability of the utility model to the heat in relieving haperacidity flue gas, as shown in Figure 1, described retracting device comprises 2-4 the flue gas heat exchanger 30 be arranged in parallel, cold pipe import 21 place of each flue gas heat exchanger 30 is furnished with valve 70 respectively, in addition, described oil pump 20 has been arranged in parallel two, so according to actual relieving haperacidity exhaust gas volumn to be processed in production, by the switching motion of the oil pump 20 of by-pass valve control 70, and then flue gas heat exchanger 30 usage quantity meeting processing requirements can be selected.
Further, described fuel tank 10 is conduction oil expansion tank, conduction oil expansion tank is adopted to store low-temperature oil, like this before supplementing low-temperature oil and carry out heat exchange in pipeline, be exhausted by conduction oil expansion tank, evaporating loss when both effectively can prevent low-temperature oil heat exchange, can guarantee again safety, stability that the utility model uses further.
