Description
Technical field
The present invention relates to a kind of hot water supply system and operation method, and in particular to a kind of using residual heat of air compressor as heat source
Closed scheme of hot-water supply and operation method.
Background technology
Air compressor machine full name air compressor, as the generating source of compressed air, is widely used in the every field of society, special
It is not in field of industrial production, many techniques rely on the height of compressed air so that air compressor machine becomes the daily fortune of many factories
The indispensable auxiliary production equipment of row, is the basic product of the modernization of industry.
Air compressor machine usually converts electrical energy into the mechanical energy of motor, and the latter is converted into gas pressure energy.Above-mentioned mistake
Cheng Zhong, air obtain strong compression, and temperature rises sharply.By taking screw machine as an example, air compressor machine screw rod is high-speed rotating at the same time, also friction hair
Heat, these heat of high temperature produced are mixed together into oil/gas steam discharge body with the air compressor lubricating oil added.Above-mentioned high temperature
70-80% of the heat of oil/gas stream equivalent to air compressor machine input power.Temperature generally reaches 80 DEG C -100 DEG C, these thermal energy need
It is discharged into by the cooling system of air compressor machine in air, to ensure temperature requirement of the machine to normal operation.If publication date is 2014
11 days 06 month, a kind of Chinese patent of Publication No. CN203641014U, just disclosed exhaust end base of oil injection threaded bolt residual heat of air compressor recycling filled
Put, which there is the above problem.
At present in many factories, in order to make full use of waste heat caused by screw-rod air compressor, air compressor machine often carry or
Separately match somebody with somebody heat exchange module, its principle generally use is played a reversed role heat transfer technology with journey shutoff type, high to high temperature caused by air compressor machine with water
Body of calming the anger is cooled down, and can not only improve the gas producing efficiency of air compressor machine, can also additionally obtain production and life needed for hot water.
