Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Referring to Fig. 1, a kind of compression heat reclamation utilization apparatus, including air compressor machine 1, air compressor machine 1 is centrifugal air compressor, pneumatics
The compressed air outlet end of machine 1 is connected to exsiccator 2 by ba level rustless steel utilidor, between air compressor machine 1 and exsiccator 2
Pipeline is provided with hot air control valve 6, and exsiccator 2 includes two adsorption towers being arranged in parallel, and desiccant 3 is located in adsorption tower,
Exsiccator 2 arranges a standby electric heater 4, and electric heater 4 is located at outside adsorption tower, and the waste heat port of export of exsiccator 2 passes through to protect
Warm pipeline connects to user 5, and the pipeline between exsiccator 2 and user 5 is provided with control valve 7, the compressed air outlet of air compressor machine 1
It is additionally provided with heat exchanger 8 between end and user 5, and the both sides of heat exchanger 8 are equipped with control valve.
Below this utility model is described in further detail:
A kind of compression heat reclamation utilization apparatus, including air compressor machine 1, air compressor machine 1 passes behind ba level rustless steel utilidor
Compression hot-air is conveyed to the adsorption tower of exsiccator 2, absorbs the moisture in the desiccant 3 in adsorption tower, so that desiccant 3
Regeneration, compressed air temperature is less than when setting value or purify air dew points at normal pressure >=-70 DEG C and just starts electric heater 4, general feelings
Under condition, (＜ -70 DEG C of purify air dew points at normal pressure) does not start electric heater 4.Air compressor machine 1 is centrifugal air compressor, three stage compression,
Type Titanium Alloy impeller is strengthened using the enhanced high-low blades formula of custom-made and two-stage intercooler to improve air compressor machine 1
Pneumatic work efficiency, improve compressed air final stage outlet temperature.Exsiccator 2 has two adsorption towers, when requiring according to technological quality
Between switch over, desiccant 3 is installed in adsorption tower, filling weight depend on technological quality require, using porous mass live
Property aluminium oxide+molecular sieve to adsorb the moisture of in the air, need to be regenerated after desiccant 3 water suction.Air compressor machine 1 and exsiccator 2
Between pipeline be provided with hot air control valve 6, hot air control valve 6 is controlled according to process conditions, and hot-air is rich in remaining
During amount, hot-air is delivered to by other heat exchangers 8 by utilidor, so that heat is made full use of further, after heat exchange, resupply use
Family 5 uses.
Particularly as follows: after centrifugal air compressor is respectively through I and II compression and I and II cooling, then through three stage compression,
110～130 DEG C of compressed airs that air compressor machine 1 final stage is produced are transported to exsiccator 2 by ba level rustless steel utilidor, are dried
The heat that device 2 makes full use of 110～130 DEG C of compressed airs of final stage generation of air compressor machine 1 carrys out the desiccant in regenerative dryer 2
3, the moisture in desiccant 3 is taken away completely.When compressed air temperature is less than setting value or purify air dew points at normal pressure >=-70 DEG C
Just start electric heater 4, generally do not start electric heater 4, hot air control valve 6 is adjusted according to process conditions,
Hot-air is rich in regulation hot air control valve 6 during surplus, by utilidor, hot-air is delivered to other heat exchangers 8, makes heat
Amount makes full use of further, resupplies user 5 and use after heat exchange.Change according to user 5 consumption adjusts control valve 7, thus adjusting
Finishing equipment load.
Therefore exsiccator not consumption of compressed air in thermal regeneration, the only just consumption when cold blowing (cool drying agent).Pressure
The waste heat of contracting air can also be supplied to user 5 to use, and change adjusting control valve 7, this heat of compression according to user's consumption simultaneously
Retracting device operation was both simple and laborsaving, saved time again, and safety, substantially increased exsiccator 2 regeneration efficiency, improved air compressor machine 1
Efficiency, when purify air technological quality is low, exsiccator 2 electric heater 4 frequency of usage is also considerably reduced, and reduces and runs production cost,
Thus reaching the purpose of energy-conservation.
