According to the oil-gas dual-recycling air compressor waste heat using device, waste heat at the lubricant side and the gas side of the air compressor is recycled, so the energy is furthest recycled, the energy consumption is reduced, the air producing efficiency of the air compressor is improved and the service life of the equipment is prolonged.
Description
Technical field
The utility model belongs to waste heat recovering device technical field, and what relate generally to is a kind of waste heat utilization device for air compressor, is applicable to the heat recovery of oil injection type screw air compressor.
Background technique
Air compressor (abbreviation air compressor) is the most widely used dynamic origin of industrial field, is widely used in mining, machine-building, building, weaving, petrochemical industry and other need the place of pressurized gas.In most of production enterprises, its energy consumption accounts for the 10%-35% of whole energy consumptions.Because air compressor is by strong compression, the part mechanical energy of prime mover to be changed into the pressure energy of gas, therefore when producing high-pressure air, can discharge amount of heat.Show according to statistics, in the electric energy consuming during compressor operating, really for increasing air potential energy only account for 15% of total power consumption, and the electric energy of all the other major parts (approximately 85%) is all converted into heat.At present, generally the mode by air-cooled or water-cooled is discharged into the heat of air compressor in air, has caused the significant wastage of the energy.
Actual detection discovery, air compressor is discharged the gas mixture temperature of body generally up to 80-100 ℃, if heat is discharged not in time, can cause serious damage to equipment, and affect gas producing efficiency.Therefore, the waste heat recovery utilization that utilizes heat-exchange apparatus that air compressor is produced, both recovered energy to greatest extent, reduced energy consumption, can improve again the gas producing efficiency of air compressor, the extension device life-span.Yet, waste heat utilization device for air compressor major part on market only reclaims for the used heat of lubricant oil one side now, the used heat of gas side is not reclaimed, single drawback that lubricant oil side used heat is reclaimed is still cannot stop the operation of former cooling system, although waste heat is utilized, the overall thermal recovery rate is not high.And the reason that cannot stop the operation of former cooling system is former cooling system, be the gentle side of oily side all to be carried out cooling, if only reclaimed for the used heat of lubricant oil one side, air cooling system originally cannot stop, and has also just caused the waste of the energy.Therefore the waste heat utilization device for air compressor that the waste heat utilization device for air compressor that, oil gas double back is received reclaims than single oily side has better using effect.
Summary of the invention
The purpose of this utility model is to propose a kind of waste heat utilization device for air compressor.This device can reclaim the used heat of lubricant oil one side, can reclaim the used heat of gas side again, realizes recovered energy to greatest extent, reduces energy consumption; Can also improve the gas producing efficiency of air compressor, the working life of extension device simultaneously.
The technological scheme that the utility model is realized above-mentioned purpose employing is: the waste heat utilization device for air compressor that a kind of oil gas double back is received comprises air compressor, cyclic water tank, the outlet of deaerator gas and former exhaust duct position at described air compressor are connected with gas side heat exchanger by two gas side maintenance valves, and between two connecting tubes, are provided with gas side bypath valve; Deaerator oil export and former thermostat valve position at described air compressor are connected with oily side heat exchanger by two oily side maintenance valves, and between two connecting tubes, be provided with oily side bypath valve, the refrigerant end of described gas side heat exchanger and the refrigerant end of oily side heat exchanger are connected in series, and described gas side heat exchanger, oily side heat exchanger and cyclic water tank are connected to become a loop body by circulating water pump.
The utility model is owing to adopting two recovery structures, it both can be reclaimed the used heat of lubricant oil one side, can reclaim the used heat of gas side again, further improved the overall thermal recovery rate of air compressor, reclaimed to greatest extent energy, reduced energy consumption, can improve again the gas producing efficiency of air compressor, the extension device life-span.At air compressor, in work, once gas side heat exchanger and oily side heat exchanger go wrong, can switch to rapidly former cooling system by gas side bypath valve and oily side bypath valve, guarantee the safe operation of oil injection type screw air compressor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, air compressor, 2, gas side bypath valve, 3, gas side maintenance valve, 4, gas side heat exchanger, 5, cyclic water tank, 6, circulating water pump subsidiary pipeline valve member, 7, oily side heat exchanger, 8, oily side maintenance valve, 9, oily side bypath valve.
Embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: the waste heat utilization device for air compressor bag air compressor 1 that the oil gas double back described in the present embodiment is received, gas side bypath valve 2, gas side maintenance valve 3, gas side heat exchanger 4, cyclic water tank 5, circulating water pump subsidiary pipeline valve member 6, oily side heat exchanger 7, oily side maintenance valve 8, oily side bypath valve 9 form.Air compressor 1 is oil injection type screw air compressor.The heating agent end of gas side heat exchanger 4 joins with the outlet of deaerator gas and the former exhaust duct of oil injection type screw air compressor 1 respectively by two gas side maintenance valves 3, between these two connecting tubes, is provided with gas side bypath valve 2.The heating agent end of oil side heat exchanger 7 joins with deaerator oil export and the former thermostat valve of oil injection type screw air compressor 1 respectively by two oily side maintenance valves 8, between these two connecting tubes, is provided with oily side bypath valve 9.The refrigerant end of gas side heat exchanger 4 and the refrigerant end of oily side heat exchanger 7 are for being connected in series, gas side heat exchanger 4 refrigerant ends, oily side heat exchanger refrigerant end 7 are connected to become a circulation by circulating water pump subsidiary pipeline valve member 6 by three with cyclic water tank 5, make circulating water not only through oily side heat exchanger 7 but also through gas side heat exchanger 4, so just formed the waste heat utilization device for air compressor that oil gas double back is received.
In work, heated circulating water first passes through oily side heat exchanger 7 refrigerant ends, then passes through gas side heat exchanger 4 refrigerant ends.Once gas side heat exchanger 4 and oily side heat exchanger 7 go wrong, can switch to rapidly former cooling system by gas side bypath valve 2 and oily side bypath valve 9, guarantee the safe operation of oil injection type screw air compressor 1.
