Abstract
The utility model discloses a compressed air system for an instrument. The compressed air system comprises a drying machine, an air compressor, an air storage tank, a first pneumatic valve, a second pneumatic valve, a third pneumatic valve and a fourth pneumatic valve, wherein the drying machine is connected with one end of the air storage tank; the first pneumatic valve is arranged between the drying machine and the air storage tank; the second pneumatic valve is connected with the other end of the air storage tank; the third pneumatic valve is connected with one end of the second pneumatic valve; the fourth pneumatic valve is connected with the other end of the second pneumatic valve; the air compressor is arranged on one side of the air storage tank and connected with the second pneumatic valve. The air compressor is provided with the air storage tank where a part of water is separated by compressed air to reduce the water content in air from an outlet of the air compressor, so that the service life of a part of components of the drying machine is prolonged, and furthermore, a unit is kept to operate stably.
Description
Technical field
The utility model, for thermal power plant, relates to a kind of air compressor.
Background technique
The existing instrument of our factory adopts and exerts oneself as 22m with air compression system
3/ min, exhaust pressure is 3, micro-whelk rod-type air compressor of 0.8MPa (gauge pressure), instrument is with the purging of pressurized air Thermal Meter when all pneumatic instruments of unit, control apparatus and the maintenance etc., and it is that SLAD-20MXF, treating capacity are the complex dryer of 22～25Nm3/min that 3 instrument have been installed 3 models by the air compressor correspondence.
In air in air compressor, water content is larger, and after entering exsiccator, the absorption of exsiccator load is very large, makes the hydrophobic amount of adsorption tower bigger than normal, has affected the working life of dryer section sub-unit.Pressurized air poor quality or hypotony, by the normal running of serious threat unit pneumatic valve, bring great harm to the safe and stable operation of unit.The spare parts such as dryer cartridge that consume are more, and automatic water trap and water that discharge large due to water displacement is sewage, often stops up hydathode, at this moment can only repair hydathode pedestrian's work draining of going forward side by side.
At instrument, with the pressurized air main-piping pressure during lower than 0.55MPa, the safe and stable operation of unit is brought to great harm; Be mainly manifested in following three aspects:
1. instrument is with compressed air pressure when too low, causes indivedual pneumatic valves can't normal running, has a strong impact on the safe and stable operation of unit.
2. when instrument is used compressed air pressure lower than 0.45MPa, hydathode will be opened automatically by the thermal control logic, can cause larger impact to unit reliability, Economy equally.
3. air compressor outlet air water content is larger, affects dryer section sub-unit working life.
Can find out that from above-mentioned three aspects instrument, by pressurized air and the quality significance to unit operation, in order to improve equipment reliability and stable, extend the working life of air compressor and exsiccator, thereby suggestion is optimized transformation to compressed air system.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of working life that extends air compressor and exsiccator, improves air quality and the reliability of equipment, the air compressor of Economy.
For addressing the above problem, the utility model adopts following technological scheme: a kind of air compressor, comprise dryer, air compressor, gas holder, the first pneumatic valve, the second pneumatic valve, the 3rd pneumatic valve and the 4th pneumatic valve, described dryer is connected with gas holder one end, described the first pneumatic valve is arranged between dryer and gas holder, described the second pneumatic valve is connected with the gas holder the other end, described the 3rd pneumatic valve is connected with an end of the second pneumatic valve, described the 4th pneumatic valve is connected with the second pneumatic valve the other end, described air compressor is arranged on a side of gas holder, and be connected with the second pneumatic valve.
As preferably, the height of described gas holder is set to 2 meter 3.
As preferably, below described gas holder, be provided with hydathode, left is provided with safety valve.
As preferably, described dryer is connected with the outlet airduct.
The beneficial effect of the utility model air compressor is: owing on described air compressor, being provided with a gas holder, pressurized air is here separated a part of moisture content, reduce air compressor outlet air water content, thereby extend dryer part parts working life, and then guarantee the stable operation of unit.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model air compressor.
Embodiment
Consult shown in Figure 1, a kind of air compressor, comprise dryer 1, air compressor 2, gas holder 3, the first pneumatic valve 4, the second pneumatic valve 5, the 3rd pneumatic valve 6 and the 4th pneumatic valve 7, described dryer 1 is connected with gas holder 3 one ends, described the first pneumatic valve 4 is arranged between dryer 1 and gas holder 3, described the second pneumatic valve 5 is connected with gas holder 3 the other ends, described the 3rd pneumatic valve 6 is connected with an end of the second pneumatic valve 5, described the 4th pneumatic valve 7 is connected with second pneumatic valve 5 the other ends, described air compressor 2 is arranged on a side of gas holder 3, and be connected with the second pneumatic valve 5.
The height of described gas holder 3 is set to 2 meter 3.Described gas holder 3 belows are provided with hydathode 8, and left is provided with safety valve 9.Described dryer 1 is connected with outlet airduct 10.
The beneficial effect of the utility model air compressor is: owing on described air compressor, being provided with a gas holder, pressurized air is here separated a part of moisture content, reduce air compressor outlet air water content, thereby extend dryer part parts working life, and then guarantee the stable operation of unit.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
