Abstract
The invention discloses a method for reducing running pressure of a common compressed air pipe network, and belongs to the technical field of energy medium production and supply. A pressure adjustment device is arranged on a main common compressed air supply pipeline of an air compressor station, is positioned on a bypass pipeline of a common compressed air storage tank, and is used for monitoring common compressed air pressure in the station and adjusting the openness of a valve in real time so as to adjust the flow of compressed air and guarantee that the air pressure entering in a dryer is relatively stable; during running, an inlet valve of the air storage tank is closed, and a bypass valve is opened, so that the common compressed air is supplied by the bypass valve and the pressure adjustment device; the pressure adjustment device adjusts upstream pressure to be stabilized between 0.73 and 0.78 MPa, and reduces downstream pressure to be between 0.5 and 0.6 MPa, so that a user can use the common compressed air; furthermore, an oil-free and water-free compressed air pipe network can run stably under high pressure, and a common compressed air pipe network can run under low pressure, so that unnecessary waste is reduced.
Description
Technical field
The invention belongs to energy medium production and supply technical field, a kind of method that reduces running pressure of common compressed air pipe network is particularly provided, be applicable to plant area's compress wind centralized production such as metallurgy, petrochemical industry, by comprehensive pipe network, unify the situation of supply.
Background technique
At present, plant area of many enterprises compress wind is by air compressor plant centralized production, by the unified supply of plant area's comprehensive pipe network.Through super-dry, process without the anhydrous compress wind of oil, because of the high using scope of its quality more and more wider, use amount increases gradually, main users is that each pneumatic element, measuring instrument and monitoring camera are first-class, required pressure is 0.4～0.6MPa, mostly be and be interrupted user, higher to the stability requirement of working pressure; And common compress wind is mainly wind and maintenance purging wind for caster two cold spray, required pressure is greater than 0.35MPa.After atmosphere is compressed by air compressor, be directly delivered into pipe network and be common compress wind; And be that the common compress wind of being produced by air compressor is prepared through purge drying equipment again without the anhydrous compress wind of oil, purge drying equipment at different levels normally hinders and damages between 0.08～0.2MPa, for guaranteeing to remain on 0.5～0.6MPa without oily anhydrous compress wind ductwork pressure, more than common compress wind pressure will be brought up to 0.6MPa, even 0.8MPa operation.
Summary of the invention
The object of the present invention is to provide a kind of method that reduces running pressure of common compressed air pipe network, guaranteeing under the prerequisite stable without oily anhydrous compress wind supply pressure, reduce running pressure of common compressed air pipe network, reach energy-saving and cost-reducing object, guarantee the stable supply without oily anhydrous compress wind.
According to compress wind actual production and supply present situation, for guaranteeing the stable supply without oily anhydrous compress wind, should guarantee the inlet pressure of purge drying equipment, be that the use amount that reduces common compress wind can realize by reducing the discharge pressure of its pipe network.
The present invention sends on main line and increases pressure regulator in the common compress wind of air compressor plant, and pressure regulator mounting point is positioned on the bypass line of common force feed wind gas holder.Pressure regulator is by the monitoring to the interior common compress wind pressure of standing, and adjusts in real time valve opening relatively stable to adjust the through-current capacity of compress wind and then blast that assurance enters exsiccator.During operation, gas holder inlet valve is closed, bypath valve is opened, and common compress wind is sent through bypath valve and pressure regulator; Gas holder outlet valve is opened, and gas holder still plays the effect that buffering is stablized ductwork pressure.Pressure regulator is adjusted upstream pressure and is stabilized in 0.73～0.78MPa, to guarantee drying apparatus inlet pressure, and then guarantees that pressure stability without oily anhydrous compress wind pipe network is at 0.6～0.64MPa; After reduction valve, the pressure of (being common compress wind pipe network), remains on 0.5～0.6MPa, meets common compress wind user's use.Realization is when guaranteeing without oily anhydrous compress wind pipe network stable high voltage operation, and common compress wind pipe network " step-down " operation, reduces unnecessary waste.
Accompanying drawing explanation
Fig. 1 is for reducing the enforcement sketch of common pipe network compress wind pipe network running pressure.Wherein, pneumatics unit 1, pressure monitoring point 2, common compress wind gas holder bypass valve 3, pressure regulator 4, cut-off valve 5, common compress wind gas holder suction valve 6, common compress wind gas holder 7, common compress wind gas holder outlet valve 8, common compress wind house steward sends valve 9, and purge drying device 10, without oily anhydrous compress wind gas holder suction valve 11, without oily anhydrous compress wind gas holder 12, without oily anhydrous compress wind gas holder outlet valve 13, without oily anhydrous compress wind gas holder bypass valve 14, without oily anhydrous compress wind house steward, send valve 15.
Embodiment
In conjunction with on-site actual situations, by the bypass line of pressure regulator installation and common force feed wind gas holder (as Fig. 1).During operation, gas holder inlet valve is closed, bypath valve is opened, and common compress wind is sent through bypath valve and controlling device; Gas holder outlet valve is opened, and gas holder still plays the effect that buffering is stablized ductwork pressure.According to the Processing capacity of air compressor unit and exsiccator unit and each user's of plant area use amount, change, constantly adjust the pressure of the unit method of operation and official website operation.Commissioning through one month is capable, and upstream pressure is remained on to 0.78MPa, and to guarantee to remain on for a long time without oily anhydrous compress wind ductwork pressure, 0.6MPa is above and pressure is more stable; Running pressure of common compressed air pipe network drops to 0.55MPa by 0.75MPa.Under identical production scale, the average use amount of common compress wind is by 375m
3/ min drops to 280m
3/ min, declines 25.3%.
