Described flowline, oil return pipe are provided with control valve.
Described heat reclamation device is the heat exchanger of playing a reversed role that dams with journey.
Compared with prior art, the heat energy that the utility model residual heat of air compressor recovery hot-water heating system will slattern originally makes full use of, and has saved the energy greatly; And the original cooling system of air compressor machine and residual heat using device be fully independently systems of two covers, need not worry because bootstrap system influences the operation of air compressor machine.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model and useful technique effect thereof are further elaborated, wherein:
Fig. 1 reclaims the structural representation of hot-water heating system for the utility model residual heat of air compressor.
Fig. 2 is the structural representation of air compressor machine internal modifications.
The specific embodiment
Residual heat of air compressor reclaims the hot-water heating system operation principle: in the long-continued running of screw air compressor, electric energy is converted to mechanical energy, mechanical energy is converted to compressed air kinetic energy, be converted in the kinetic energy process in mechanical energy, atmospheric air (about 1bar) obtains the strong pressure-air (general 7-13bar) that is compressed to, the volume of air reduces, and simultaneous temperature rises sharply, and this is a general physics mechanical energy conversion phenomena; The high speed of machinery rotation simultaneously, also frictional heating.Above process produces a large amount of heats, and these heat energy are because the needs of compressor operation temperature are discharged body by the air compressor machine cooling system usually, and this part heat is equivalent to 3/4 of air compressor machine input power, and its temperature is usually at 80 ℃-105 ℃.For energy savings, air compressor machine is passed to cold oil at the waste heat that is produced that runs well, cold oil carries out exchange heat with water in heat reclamation device, with heat transferred water.
The workflow of air compressor: air by air intake filter with dust in the atmosphere or impurity filtering after, enter compressor host by air intake control valve, in compression process, mix with the cutting oil that sprays into, mist after compression enters catch pot from compression chamber, obtains oil, the gas of HTHP after gs-oil separator separates.Because the requirement of machine works temperature, the cooler that the oil of these HTHPs, gas must enter separately cools off, and wherein compressed air enters using system from exhaust outlet of compressor at last after the cooler cooling; And the lubricating oil of HTHP returns oil circuit and enters the next round circulation after the cooler cooling.
As shown in Figure 1 and Figure 2, residual heat of air compressor reclaims hot-water heating system and comprises that two air compressor machines 100, two are with the journey heat exchanger 200 of playing a reversed role that dams, air compressor machine 100 is communicated with flowline 4, the oil return pipe 5 of heat exchanger 200 by separately of playing a reversed role of damming with journey, and two are communicated with attemperater by water inlet pipe 6, return pipe 7 with the dam heat exchanger 200 of playing a reversed role of journey.Mixed oil and gas through compression in air compressor host 101 enters Oil-gas Separation bucket 102 from oil gas mixing inlet 103, compressed air enters using system through exhaust outlet 104, the lubricating oil outlet 105 of Oil-gas Separation bucket 102 is connected with oil cooling radiator 107 by main oil pipe 106, oil cooling radiator 107 and air compressor host 101 are communicated with by oil pipe, main oil pipe 101 is provided with temperature-sensing valve 108, the other end of temperature-sensing valve 108 directly is communicated with by oil pipe with air compressor host 101, main oil pipe 101 is by flowline 4, oil return pipe 5 is communicated with the heat exchanger 200 of playing a reversed role of damming with journey, at flowline 4, main oil pipe section in the middle of the oil return pipe 5 is provided with ball valve 8, flowline 4, be respectively arranged with control valve 401 on the oil return pipe 5,501.
Dam when playing a reversed role heat exchanger 200 when starting with journey, ball valve 8 is closed, control valve 401,501 is opened, the cold oil that comes out from lubricating oil outlet 105 flows to flowline 4 through main oil pipe 106 and enters the dam heat exchanger 200 of playing a reversed role of journey and carry out exchange heat, and it is recycling that the cold oil of finishing exchange heat returns air compressor host 101 by oil return pipe 5 through main oil pipe 106; Temperature-sensing valve 108 detects the temperature of the cold oil that returns, and when temperature is still too high, is undertaken entering air compressor host 101 again after heat is distributed by oil cooling radiator 107.
The heat exchanger 200 of playing a reversed role when damming with journey is stopped using or when breaking down, ball valve 8 is opened, and control valve 401,501 is closed, and it is recycling that the cold oil that comes out from lubricating oil outlet 105 directly returns air compressor host 101 through main oil pipe 106; Temperature-sensing valve 108 detects the temperature of the cold oil that returns, and when temperature is still too high, is undertaken entering air compressor host 101 again after heat is distributed by oil cooling radiator 107.
