Description
Technical Field
The invention relates to a method for stabilizing pressure by networking a plurality of large-scale centrifugal air compressor stations.
Background
The power consumption of the air compression station for the power of the steel enterprise is more than 5%, in the past, a steel plant is provided with more than 10 air compression stations according to units, most oil screw air compressors and piston machines are used, the efficiency is low, and the energy consumption is high. Along with the gradual replacement of small screw rods and small piston machines by large-scale high-efficient centrifugal air compressors, the energy conservation of large-scale centrifugal air compressor stations is remarkable, but in the prior art, the balance of loads in all areas of a plurality of networked centrifugal air compressor stations and the balance of total demands and total supply avoid causing the waste of the machines of a plurality of air compressor stations by diffusion at the same time and the waste of energy resources of frequent startup and some emptying due to the defects of a plurality of air compressor stations.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for networking a plurality of large-scale centrifugal air compressor stations to stabilize pressure, which effectively prevents the waste of air pressure emptying caused by air pressure imbalance of each area and also effectively eliminates emptying waste and equipment abrasion caused by frequent start and stop of the machine due to imbalance of total supply and total demand.
The technical scheme for solving the technical problems is as follows: a method for networking and stabilizing pressure of a plurality of large-scale centrifugal air compressor stations specifically comprises the following steps:
constructing and networking a plurality of main outlet pipelines of a large centrifugal air compressor station;
(II) a central controller is arranged in one large-scale centrifugal air compressor station, and the central controller uniformly controls guide vanes and emptying valves of each centrifugal air compressor in all the areas;
when the total supply is greater than the total demand, closing one or more air compressor guide vanes in the area, and reducing the supply amount to balance the air compressor guide vanes; when the total supply is in a small surplus total demand, the guide vanes of all the air compressors are gradually enlarged until the guide vanes are still insufficient after all the air compressors are opened, and then the centrifugal air compressors in other areas are started to meet the demand.
The invention further adopts the technical scheme that:
at least 2 large-scale centrifugal air compressor station main outlet pipelines are constructed and networked.
Each large-scale centrifugal air compressor station has at least 3 air compressors.
The invention has the beneficial effects that: after a plurality of air compression station outlet main pipe networks are networked, the load of each area is balanced, and the waste condition that a plurality of air compression stations are simultaneously diffused is avoided; meanwhile, the invention changes the single control of a single large-scale centrifugal machine into centralized control, thereby effectively avoiding the waste conditions of full load and emptying of any air compressor in the networking; the energy saving rate of the energy-saving device reaches 5.03 percent, the energy consumption is greatly reduced, and the production cost is saved.
