A kind of residual heat of air compressor reclaiming system
Technical field
The present invention relates to the heat recovery technology field, relate to a kind of residual heat of air compressor reclaiming system more specifically.
Background technique
Continuous development along with industrial technology, air compressor is widely used in every field such as electric power, weaving, iron and steel, food, the energy, automobile, chemical industry, and air compressor commonly used in the prior art comprises piston type air compressor and screw air compressor, centrifugal compressor, sliding-vane compressor and scroll type air compressor.Following content will be example with the screw compressor, and introduction is described in detail in detail.
The working principle of screw air compressor can be as described below.Screw air compressor is rotated in cylinder by the negative and positive rotor (or claiming screw rod) of a pair of engagement that is parallel to each other, make the air between the rotor teeth groove constantly produce periodic volume-variation, air then is delivered to outlet side along rotor axis by the suction side, thereby realizes the overall process of air-breathing, compression and the exhaust of air compressor.
Screw air compressor is converted to mechanical energy to electric energy in long-continued running, mechanical energy is converted to wind energy, be converted in the wind energy process in mechanical energy, air obtains strong high pressure compressed, makes it temperature and rises sharply, and this is general physics mechanical energy conversion phenomena.
The mechanical screws of screw air compressor is in the high speed rotary course, while is frictional heating also, these are conducted in the air compressor lubricant oil by fricative Gao Rere, air compressor lubricant oil with high temperature generates oil gas and discharges body, the heat of above-mentioned high temperature oil and oil gas is equivalent to the 25-30% of air compressor input power, and its temperature is usually in 80 ℃ of (winter)-100 ℃ (summer and autumn).Because the requirement of machine running temperature, these heat energy are discharged in the atmosphere as used heat by the radiation system of air compressor.So, caused the problem of more serious thermal waste.
Therefore, how to avoid the problem of the thermal waste that air compressor causes in the prior art, become those skilled in the art's important technological problems to be solved.
Summary of the invention
