The two-stage heat exchange improved device is characterized by comprising the air compressor, oil pipelines, valves, a primary heat exchanger, a circulating water pump, heat media, a secondary heat exchanger, a heat exchange device and the like, and the primary heat exchanger is serially connected onto an air cooling radiating device of the air compressor by the corresponding oil pipeline. The two-stage heat exchange improved device has the advantages that the two-stage heat exchange improved device mainly comprises the two heat exchangers and the single circulating water pump, the two heat exchangers are connected with each other by the oil pipelines, the valves and the circulating water pump, a heat transfer medium in the pipelines is anti-corrosion and high-temperature-resistant anti-freezing liquid, accordingly, only heat exchangers in a heat storage water tank side need to be conventionally chemically or mechanically cleaned on the premise that normal functions of the waste heat recycling system for the air compressor are guaranteed, heat exchangers on an air compressor side do not need to be cleaned, potential risks of internal leakage of the heat exchangers and halting and even scraping of the air compressor due to the original one-time heat exchange mode can be eliminated, and the air compressor can be protected and runs safely and efficiently.
Description
Technical field
The utility model relates to heat exchange field, relates in particular to a kind of secondary heat exchange waste heat recovery system of air compressor modifying device.
Background technique
China's afterheat recovery unit of air compressor application is at present comparatively general, its basic principle is, by heat-exchanger rig, compressor oil cooling system is carried out to heat recovery, for enterprise produces hot water, thereby reduce air compressor energy loss, raising air compressor working efficiency, minimizing enterprise hot water production expense.In existing waste heat recovery system of air compressor, the heat exchange form of heat-exchanger rig is heat exchange form one time, is only a heat exchanger, and heat exchanger first side is concatenated into compressor oil pipeline, and second side is water system.Along with the use of waste heat recovery apparatus; in heat exchanger, easily produce incrustation scale; need heat exchanger at set intervals to carry out chemistry or mechanical cleaning; along with the increase of wash number can cause the damage of heat exchanger inwall entirety and pitting corrosion; again because heat exchanger first side, second side pressure difference are larger; so just have the potential risk of interior leakage of heat exchanger, the situation that causes air compressor because of medium infiltration disorderly closedown, even to be scrapped occurs, and affects normal production and application.
Summary of the invention
According to above technical problem, the utility model provides a kind of secondary heat exchange waste heat recovery system of air compressor modifying device, it is characterized in that comprising air compressor, oil pipe line, valve, first-class heat exchanger, circulating water pump, thermal medium, secondary heat exchanger, heat-exchanger rig, temperature transducer, hot water storage tank, controller, air compressor air-cooled radiating device, No. one time heat exchanger is concatenated on air compressor wind-cooling heat dissipating by oil pipe line, on described oil pipe line, valve is installed, described first-class heat exchanger is connected with secondary heat exchanger by oil pipe line, on described this oil pipe line, valve is installed, circulating water pump, in described oil pipe line, be loaded with heat transfer medium, described secondary heat exchanger passes through oil pipe line, circulating water pump is connected with hot water storage tank, on described hot water storage tank, temperature transducer is installed, described controller is respectively to air compressor, valve, circulating water pump, hot water storage tank connects control, described first-class heat exchanger, circulating water pump, secondary heat exchanger composition heat-exchanger rig.
Described heat transfer medium adopts the antifreeze liquid with anticorrosion and resistance to high temperature.
The utility model beneficial effect: the utility model is by improving the heat exchange form of heat-exchanger rig; avoid heat-exchanger rig to cause internal leakage because of conventional chemical or mechanical cleaning; thereby cause air compressor disorderly closedown, even the situation of scrapping occurs; improve greatly the reliability of waste heat recovery system of air compressor; this device adopts pollution-free green material, has reduced environmental pollution.Heat-exchanger rig after the utility model improves is mainly made up of two heat exchangers and a circulating water pump, between two heat exchangers by oil pipe line, valve and circulating water pump connect, in its pipeline, heat transfer medium adopts the antifreeze liquid with anticorrosion and resistance to high temperature, ensureing under the prerequisite of waste heat recovery system of air compressor normal function, only need carry out conventional chemical or mechanical cleaning to hot water storage tank side heat exchanger, pneumatics pusher side heat exchanger is without cleaning, eliminate a former heat exchange form bring because of interior leakage of heat exchanger cause air compressor shut down, the potential risk of even scrapping, effectively protection air compressor safety, efficient operation.In heat-exchanger rig of the present utility model, a heat exchanger is concatenated on air compressor wind-cooling heat dissipating oil pipe line by oil pipe line and valve, secondary heat exchanger is connected to hot water storage tank by oil pipe line, circulating water pump, and heat recovery system ensures its safety, reliable operation by temperature transducer, controller, valve.
