Fig. 2 is the utility model embodiment's an a kind of air-cooled air compressor heat recovery system schematic representation.
Embodiment
In whole cold oil cyclic process, mainly containing two places has greatly influenced waste heat and heat recovery efficiency that heat recovery system reclaims:
Distributed a large amount of recyclable " used heat " to the external world when 1, cold oil is through oil cooler;
2, owing to the regulating action of thermostat valve, the high temperature cold oil of process heat exchanger reduces in a large number, makes " used heat " that reclaims through heat exchanger a large amount of minimizings.
According to the above-mentioned two problems point, the present invention adopts temperature transducer and frequency-variable controller that the oily temperature in the oil cooler is controlled, and the high temperature oil that enters thermostat valve is reduced, thereby order rolls up through " used heat " that transducer reclaims.
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 2, it is the utility model embodiment's an a kind of air-cooled air compressor heat recovery system schematic representation.This air-cooled air compressor heat recovery system is in order to reclaim the heat energy that air compressor produces, and it comprises gas and oil separating plant 205, heat exchanger 207, oil cooler 211, thermostat valve 213, oil strainer 215, temperature transducer 217 and frequency-variable controller 219.Gas and oil separating plant 205 is connected to air compressor head 203, heat exchanger 207 links to each other with gas and oil separating plant 205, oil cooler 211 links to each other with heat exchanger 207, thermostat valve 213 links to each other with gas and oil separating plant 205, oil cooler 211 and oil strainer 215 respectively, and oil strainer 215 is connected to air compressor head 203.Temperature transducer 217 is in order to measure the oil temperature in the oil cooler 211, and it links to each other with oil cooler 211.Frequency-variable controller 219 is in order to the frequency of okperation according to the fan motor of the survey data of temperature transducer 217 control oil cooler 211, and it links to each other with fan motor in temperature transducer 217 and the oil cooler 211 respectively.What the frequency-variable controller 219 in the present embodiment adopted is the VFD controller.
