Description
Technical field
The utility model relates to the device that a kind of chilldown system reduces corrosion and fault rate, is specifically related to a kind of small-sized empty chilldown system cooling, dehydrating unit of dividing.
Background technology
At present, the employed small-sized empty structure of chilldown system cooling, dehydrating unit of dividing of a lot of enterprises is as shown in Figure 1, is made up of air compressor machine 1 and precooling unit 3; Pipeline is provided with air compressor machine air delivery valve 11 and-air compressor machine atmospheric valve 12, but the device of this structure has the partial condensation elutriation and goes out after air compression cooling; This part compresses cooled saturated moist air in the flow at high speed process, can compress air separation unit, the aluminum fin formula heat exchanger in the chilldown system equipment washes away and form corrosion, and moisture is high more; Corrode serious more; And inlet air temperature is high more, and its operational outfit load is heavy more, and fault rate is high more.
Summary of the invention
The utility model divides chilldown system ubiquity seriously corroded, the problem that fault rate is high in order to solve existing small-sized sky, and a kind of small-sized empty chilldown system cooling, dehydrating unit of dividing is provided.
The utility model is realized through following technical scheme:
Small-sized empty chilldown system cooling, the dehydrating unit of dividing; Comprise air compressor machine and precooling unit; Wherein also comprise fractionating column, air cooling tower, water-cooling tower, low temperature water pump; Described fractionating column is connected with the water-cooling tower bottom air inlet through two pipelines that are respectively equipped with low pressure nitrogen air delivery valve and dirty nitrogen air delivery valve; Described water-cooling tower top water inlet is connected through the pipeline that is provided with the air cooling tower Liquid level adjusting valve with the air cooling tower bottom; Water-cooling tower bottom delivery port is connected through the pipeline that is provided with low temperature water pump and Water flow adjusting valve with air cooling tower top water inlet, and described air cooling tower is connected with the precooling unit, and described air compressor machine is connected through the pipeline that is provided with air compressor machine air delivery valve and air compressor machine atmospheric valve with air cooling tower.
During use, waste gas such as the low pressure nitrogen that fractionating column diffuses, dirty nitrogen are introduced reverse contact of soft water that water-cooling tower and cat head spray; Utilize waste gas low temperature, dry characteristics to produce water at low temperature; With low temperature water pump water at low temperature is squeezed into the air cooling cat head again, reduce saturation air temperature, reduce airborne moisture with reverse contact of hot-air that air compressor machine is sent here; Air gets into the precooling unit more then, realizes the unit light(-duty) service.
The utility model design is ingenious, easy and simple to handle, rationally utilizes waste gas cooling soft water such as low pressure nitrogen, dirty nitrogen, reduces moisture and temperature in the saturated air, has realized reducing the corrosion of precooling unit and the purpose of fault rate.
