Description
Technical field
The utility model relates to residual heat of air compressor and utilizes technical field, and specifically, it is that a kind of residual heat of air compressor of double mode automatic operation utilizes system.
Background technique
Present heat recovery system for air compressor or heat recovering device mostly adopt independently endless form or directly-heated mode to carry out heat energy utilization, and two kinds heat mode pluses and minuses are respectively arranged.Usually endless form cold water directly covers water storage box, progressively promote water temperature by the unit circulating-heating again, this kind heating mode has increased the stand-by period before user side uses, but when water consumption occurring when relatively more concentrated, cistern water level descends rapidly, be the guaranteed water level requirement, cold water covers rapidly water tank, mixes with high-temperature water in the water tank, so that the water tank water temperature descends rapidly, thereby caused the more and more lower situation of water temperature in client's using process, fluctuating temperature is larger.And the directly-heated mode normally makes cold water directly enter heat exchanger, the water-exit temperature value of setting is compared with actual water-exit temperature value, after calculating, control system regulates the aperture of water inlet mortor operated valve, regulate the flow of cold water, make water-exit temperature reach the mode that heats of setting temperature, the defective of this kind heating mode is after water storage box is filled with water, the cold water mortor operated valve must cut out, otherwise water storage box will spilling water, and at this moment, the heat energy of air compressor just can't be recycled.Therefore, all there is certain narrow limitation in these two kinds of heating modes.
Summary of the invention
For the deficiencies in the prior art part, the residual heat of air compressor that the purpose of this utility model provides a kind of double mode automatic operation of effective lifting air compressor heat reclaiming system heat utilization rate utilizes system.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of residual heat of air compressor of double mode automatic operation utilizes system, comprise cold water source entrance, water inlet mortor operated valve, the heat exchanger that is connected with thermal source, circulation electric valve, water storage box and PLC control module, connect the cold water inlet of heat exchanger behind described cold water source entry sequence connection filter, water inlet mortor operated valve and the first one-way valve, the cooling water outlet of this heat exchanger connects the water inlet of water storage box; The water outlet of described water storage box is linked in sequence and connects the cold water inlet of heat exchanger behind recycle pump, circulation electric valve and the second one-way valve; Described PLC control module connects and control water inlet mortor operated valve, circulation electric valve, recycle pump, be arranged at water level detecting module in the water storage box, be arranged at the heat source temperature testing module between thermal source and the heat exchanger and be arranged at heat exchanger and water storage box between the sink temperature testing module.
Compared with prior art, the beneficial effects of the utility model are: by above-mentioned structural design, namely by the first heat-exchange system that is formed by cold water source, water inlet mortor operated valve, heat exchanger and water storage box and the second heat-exchange system that is formed by circulation electric valve, heat exchanger and water storage box, and the PLC control module of controlling above-mentioned two heat-exchange systems, can solve the deficiency that exists in the technology in the existing heat recovery system for air compressor, effectively improve air compressor heat reclaiming system heat utilization rate.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the residual heat of air compressor of a kind of double mode automatic operation of the utility model utilizes system, comprise cold water source entrance 1, water inlet mortor operated valve 3, the heat exchanger 5 that is connected with thermal source, circulation electric valve 8, water storage box 6 and PLC control module 10, described cold water source entrance 1 is linked in sequence and connects the cold water inlet of heat exchanger 5 behind filter 2, water inlet mortor operated valve 3 and the first one-way valve 4, and the cooling water outlet of this heat exchanger 5 connects the water inlet of water storage box 6; The water outlet of described water storage box 6 is linked in sequence and connects the cold water inlet of heat exchanger 5 behind recycle pump 7, circulation electric valve 8 and the second one-way valve 9; Described PLC control module 10 connects and control water inlet mortor operated valve 3, circulation electric valve 8, recycle pump 7, be arranged at water level detecting module 11 in the water storage box 6, be arranged at the heat source temperature testing module 12 between thermal source and the heat exchanger 5 and be arranged at heat exchanger 5 and water storage box 6 between sink temperature testing module 13.
Generally cold water source is tap water, and certain pressure is arranged, and does not have pressure such as cold water source, can consider to increase water pump.
Working principle of the present utility model is, when water level detecting module 11 detects water storage box 6 water levels and is in low water level, after the temperature value of PLC control module 10 collection heat source temperature testing modules 12 and sink temperature testing module 13 is also processed as calculated, regulating water inlet mortor operated valve 3 opens, directly enter water storage box 6 after 5 heat exchange of cold water process heat exchanger, this moment, system works was at the directly-heated heating mode; When water level detecting module 11 detects water storage box 6 water levels and is in high water level, PLC control module 10 is closed into water mortor operated valve 3, opens circulation electric valve 8, ON cycle pump 7, water flows back to again water storage box by water storage box 6 through recycle pump 7, circulation electric valve 8, and system works is in the circulating-heating pattern.
When water storage box 6 water levels arrived middle water level, after PLC control module 10 control water inlet mortor operated valves 3 and circulation electric valve 8 all were opening state, hot and cold water entered heat exchanger 5 heat-obtainings after mixing, and raises the efficiency.
In sum, the utility model is by above-mentioned structural design, solved the deficiency of circulating-heating mode and directly-heated mode of heating in the existing heat recovery system for air compressor, effectively promotes the utilization efficiency of heat energy of heat recovery system for air compressor.
