Technical field
The utility model relates to air compressor waste heat and recycles field, the efficient heat recovery system of particularly a kind of air compressor.
Background technique
The application of China's air compressor is very extensive at present, the air compressor of wherein a large amount of electronics and light industry all is the radiating mode that adopts air-cooled structure or water-cooling structure, the radiating mode of air-cooled structure is meant the heat discharge that air compressor is produced by fan to atmosphere, and the radiating mode of water-cooling structure is meant by cooling water takes away the heat that air compressor produces.Yet these two kinds of radiating modes are the heat that air compressor produces to be discharged in the atmosphere or in the water in vain slatterned, and from energy-conservation and angle environmental protection, should make full use of this part heat, and it is converted to can be by the energy that utilizes again in enterprise or the daily life.
Can be recovered the purpose of utilization for " used heat " of realizing the air compressor generation, now released a kind of air compressor with heat recovery function, it can be converted to hot water with " used heat ", sees also Fig. 1, and it is existing a kind of structural representation with air compressor of heat recovery function.This air compressor with heat recovery function comprises air compressor motor 101, air compressor head 103, Oil-gas Separation tube 105, heat exchanger 107, oil cooler 111, first thermostat valve 113 and oil strainer 115.
Air compressor is when work, and its air compressor head 103 is driven by motor 101, and produces heat, and the oil temperature in the air compressor is constantly raise.Enter heat exchanger 107 after high temperature oil is separated by Oil-gas Separation tube 105 this moment.High temperature oil in heat exchanger 107 and water carry out being admitted in the oil cooler 111 after the exchange heat, and carry out exchange heat once more with the air or the water in the external world, temperature is significantly reduced once more.After the low temperature oil after twice cooling enters the low temperature oil inlet end of first thermostat valve 113.Wherein, high temperature oil is carried out exchange heat with water in entering heat exchanger 107 after, the water that will have uniform temperature is stored in the heat-insulating water tanks 109, so that the heat energy that water is obtained is realized utilizing again.Therefore the such design of the air compressor waste of having saved heat energy to a certain extent.
But, air compressor in the normal operation, the returning-oil temperature of cold oil can not be low excessively, and oil cooler 111 tends to fall the temperature of oil low excessively, and therefore the effect of first thermostat valve 113 is used for just guaranteeing that the oil that cools off maintained on the allowable temperature before entering air compressor head 103.Thermostat valve 113 links to each other with oil cooler 111, oil strainer 115 and Oil-gas Separation tube 105 respectively, because it is low that the cooling oil temperature that flows into first thermostat valve 113 from oil cooler 111 is spent, and then must introduce more high temperature oil from Oil-gas Separation tube 105 and come " neutralization " this low temperature.Therefore, under the regulating and controlling effect of first thermostat valve 113, along with high temperature oil flows into first thermostat valve 113, the high temperature oil of the heat exchanger 107 of flowing through then correspondingly reduces, thereby the heat energy of exchange feedwater also will reduce, and has also just caused " used heat " that reclaims in the heat recovery system unit time to reduce in a large number.
In sum, existing air-cooled air compressor exists the problem of heat recovery efficiency difference.

Fig. 2 is the efficient heat recovery system schematic representation of a kind of air compressor of the utility model embodiment.
Embodiment
In whole cold oil cyclic process, mainly containing two places has greatly influenced waste heat and heat recovery efficiency that heat recovery system reclaims:
Distributed a large amount of recyclable " used heat " to the external world when 1, cold oil is through oil cooler;
2,, " used heat " that reclaims through heat exchanger is also reduced in a large number because first thermostat valve need be introduced some high temperature oil from gas and oil separating plant and make regulating action, and therefore the high temperature cold oil through heat exchanger reduces in a large number.
According to the above-mentioned two problems point, the present invention adopts second thermostat valve to control and flows into the oil mass of cooling off in the oil cooler, thereby the recyclable used heat that reduces even avoided losing from oil cooler, " used heat " that reclaims through transducer is rolled up.
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 2, it is the utility model embodiment's the efficient heat recovery system schematic representation of a kind of air compressor.The efficient heat recovery system of this air compressor comprises gas and oil separating plant 205, heat exchanger 207, heat-insulating water tanks 209, oil cooler 211, second thermostat valve 217 that has first thermostat valve 213, the oil strainer 215 of two oil inlet ends and an oil outlet end and have two oil inlet ends and an oil outlet end.Gas and oil separating plant 205 is connected to air compressor head 203, heat exchanger 207 links to each other with gas and oil separating plant 205, heat-insulating water tanks 209 links to each other with heat-insulating water tanks 209, oil cooler 211 links to each other with heat exchanger 207, an oil inlet end of first thermostat valve 213 links to each other with gas and oil separating plant 205, and oil outlet end is connected to air compressor head 203.An oil inlet end of second thermostat valve 217 links to each other with heat exchanger 207, and another oil inlet end links to each other with oil cooler 211, and oil outlet end is connected to another oil inlet end of first thermostat valve 213.
Before air compressor work, to the temperature threshold values of first thermostat valve 213 and second thermostat valve 217 be provided with earlier, make the oily temperature that enters first thermostat valve 213 and second thermostat valve 217 must satisfy being provided with of its temperature threshold values and could pass through its oil outlet end.When air compressor was worked, its air compressor head 203 was driven by motor 201, and produces heat, and the oil temperature in the air compressor head 203 is constantly raise.Enter heat exchanger 207 after high temperature oil is separated by gas and oil separating plant 205 this moment.High temperature oil in heat exchanger 207 and water carry out exchange heat, oily temperature is significantly reduced, and the water that will obtain heat is stored in the heat-insulating water tanks 209, so that will utilize its heat energy after the water derivation.
After high temperature oil and the end of water heat-shift, just from heat exchanger 207, flow out, at this moment, if oily temperature is higher than the temperature threshold values of second thermostat valve 217, then under the regulating action of second thermostat valve 217, most oil enters an oil inlet end of second thermostat valve 217.And the oil of small part enters and lowers the temperature in the oil cooler 211, and the low temperature oil after oil cooler 211 coolings flows into another oil inlet end of second thermostat valve 217 again.Then, second thermostat valve 217 regulates and control to make two oil in the oil inlet end to mix, and when oily temperature reaches the temperature threshold values of second thermostat valve 217, flows into an oil inlet end of first thermostat valve 213 from the oil outlet end of second thermostat valve 217.Another oil inlet end of first thermostat valve 213 is introduced a spot of high temperature oil from gas and oil separating plant 205.Then, first thermostat valve 213 mixes the oil of two oil inlet ends, and regulates and control when air compressor normally moves the returning-oil temperature of permission, returns air compressor head 203 after filtering out impurity through oil strainer 215 again.
In this process, have only a spot of oil to enter in the oil cooler 211 and lower the temperature, thereby make that the used heat of loss is considerably less in oil cooler 211.And, low excessively because there is the temperature threshold values of second thermostat valve 217 to limit the oily Wen Buhui that flows into first thermostat valve 213 again, so 213 need of first thermostat valve are introduced very small amount of high temperature oil from gas and oil separating plant 205, just can make oily temperature reach the returning-oil temperature that air compressor normally moves permission.Carry out waste heat recovery so just guaranteed to have abundant high temperature oil to flow into heat exchanger 207, that is to say the efficient that has increased waste heat recovery.
If through with the water heat-shift after and the oil temperature that from heat exchanger 207, flows out during less than the temperature threshold values of second thermostat valve 217, then whole oil enters the oil inlet end of second thermostat valve 217, directly enter an oil inlet end of first thermostat valve 213 again by the oil outlet end of second thermostat valve 217, together after a small amount of high temperature oil mixing that another oil inlet end of first thermostat valve 213 is introduced, regulate and control to the returning-oil temperature of the normal operation of air compressor through first thermostat valve 213, return air compressor head 203 after process oil strainer 215 filters out impurity again.
In this process, fully process oil cooler 211 coolings of oil, thereby the used heat that the oil temperature in the whole process produces has equally also improved the efficient of heat recovery fully by heat exchanger 207 recovery.
Than prior art, the utlity model has following advantage: the utility model is provided with second thermostat valve in heat recovery system for air compressor, the recyclable used heat that had both reduced even avoided losing from oil cooler, guarantee the abundant high temperature cold oil heat exchanger of flowing through again, increase the yield of used heat greatly, improved the efficient of heat recovery system.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the present utility model.
