Description
Technical field
The utility model belongs to the long compressed air system of thermal power generation, is specifically related to a kind of compressed air system of combination type drying machines.
Background technology
Thermal Power Station's compressed air system is generally made up of (as shown in Figure 1) air compressor, combined type (freezing type+absorption type) drying machine, filter, air accumulator, gas pipeline, valve:
Air compressor: air, through the air inlet collection of air compressor, after air compressor compression, enters drying machine from the gas outlet of air compressor.Air due to air inlet collection ejects compressed air with the rear gas outlet of acting and there is temperature difference, must separate out most condensed water simultaneously containing a small amount of oil and impurity;
Drying machine: combination type drying machines (freezing type+absorption type) removes the moisture in compressed air, makes compressed air reach instructions for use;
Filter: in main conduit line, main pipeline filter must have minimum Pressure Drop and mist of oil separating power, and it makes dust out in pipeline, moisture content and oil;
Air accumulator: holding compressed air, and the effect playing buffering, can maintain compressed air system pressure stability;
Gas pipeline: be to the pipeline using point by compressed air delivery.As long as reach flow, pressure, pure quiet degree that compressed air uses point to require.
Compressed air system is generally made up of 4 air compressor machines and drying machine, and 2 operations during normal operation, 1 operation is for subsequent use, 1 overhaul reserve.The air that air compressor machine is discharged meets with gas point the technical parameter requirement of air quality after the process of air oxygen detrition cleaning equipment.Compressed air system be generally provided with 3 instrument air accumulators and 1 use mixedly air accumulator.4 air compressor interlocked control, can self-starting.
