[embodiment]
Below by specific embodiment, by reference to the accompanying drawings the utility model is described further, following embodiment is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.
Embodiment 1
As shown in Figure 1, wherein screw compressor has been very ripe and known machinery, the present embodiment mainly lays particular emphasis on transformation deaerator outlet oil circuit part can carry out sufficient UTILIZATION OF VESIDUAL HEAT IN, the screw rod of air compressor rotarily drives air and compresses, lubricant oil carries out constantly cooling to the air of air compressor, the mixture of pressurized air and lubricant oil is sent in the outlet of last air compressor, this mixture enters and in deaerator, carries out separation, wherein clean air be sent to after separated in the second cooler, carry out cooling, after cooling, deliver to gas holder.
The lubricant oil part of High Temperature High Pressure is carried out the utilization of waste heat through our energy-saving equipment, its structure is as follows: oil circuit connects successively vaporizer, the first cooler and is connected with described air compressor after filter, also comprise a circulating refrigerant pipeline, successively through recycle pump, with oil circuit by vaporizer be connected heat exchange, be connected with turbogenerator, finally and condensed device connect and compose circulation, generator generating end is connected with electrical network with after transformation pressure stabilizing device, the upper cooling line that is also provided with of described condensed device.Described deaerator is provided with oil level indicator.Hot water outlet on vaporizer is connected with a heat-insulating water tanks by pipeline.The hot water of collecting in heat-insulating water tanks can be for life or industrial water.
The lubricant oil of High Temperature High Pressure enters vaporizer to the refrigerant heating in refrigerant pipeline, refrigerant is undergone phase transition, by low temperature liquid, change High Temperature High Pressure gaseous state into, thereby promote the turbine rotation generation Ac of turbogenerator, after transformation voltage stabilizer, send into load electrical network.Lubricant oil temperature after the first cooler reduces, then after being filtered, reenters air compressor screw rotor and air is mixed together the gas mixture that is compressed into High Temperature High Pressure.High Temperature High Pressure gaseous coolant from generator out laggard condenser and cooling water carry out heat exchange and again undergo phase transition cooling, become the state of low temperature liquid, thereby be transported to vaporizer by recycle pump, reheat acting and recycle.
