Energy-saving control system for air compressor group

Abstract

The invention discloses an energy-saving control system for an air compressor group. The air compressor group is arranged in an air compressor room; a pipe network of the air compressor group consists of a main pipe network and a plurality of branch pipe networks; the main pipe network is communicated with a gas storage tank; the gas storage tank is positioned between the air compressor room and the branch pipe networks; each branch pipe network is correspondingly communicated with each air compressor of an air compressor unit through the main pipe network; a power supply lead of the air compressor unit is connected with an air compressor power distribution cabinet which is used for supplying power to a motor of each air compressor; the control system comprises a parameter monitoring module, an optimal control module and a display alarming module; the parameter monitoring module is used for monitoring parameters of the pipe network and the air compressor unit in real time and transmitting information to the optimal control module; the optimal control module is used for respectively controlling the air compressor unit and the display alarming module to work; and a manager acquires work information of the air compressor group through the display alarming module and correspondingly manages the pipe network and the air compressor unit. According to the energy-saving control system, comprehensive management for the whole air compressor system can be realized and the aim of maximizing energy saving is achieved.

Description

technical field [0001] The invention relates to the field of energy saving of pneumatic systems, in particular to an energy saving control system for air compressor groups. Background technique [0002] The control system of the air compressor group is the core technology in the field of energy saving of the pneumatic system. The pneumatic system based on compressed air has been widely used in modern industry due to its relatively low cost, no pollution, and easy maintenance. At the same time, the pneumatic system is also an important means to improve production efficiency and realize the automation of production process in modern industry. In the industrial pneumatic system, the power consumption of the pneumatic system is mainly in the production of compressed air, and the production of compressed air is completed by the air compressor. Due to frequent and large changes in the load of the pneumatic system, it is particularly important to rationally configure the air compr...

Problems solved by technology

However, the energy-saving means of installing frequency converters is only applicable to the situation where the air compressor is unloaded, and the industrial and mining enterprises with 24-hour continuous production often set the loading pressure of the air compressor to ensure that there is sufficient pressure at the terminal gas point If the setting is too low, the unloading pressure setting is too high, so that the air compressor is always in a loaded state. In this case, it is invalid to install a frequency converter to save energy.

Since the inverter itself also consumes power, it not only does not save energy but consumes more energy
