Pre-treating and variable-flow device of air compression system

Abstract

The invention provides a pre-treating and variable-flow device of an air compression system, wherein the wind outlet of an air pre-cooling machine set is connected with an air compressor; the wind outlet of the air compressor is connected with an air / oil cooler; a cold spray evaporation nozzle of the air / oil cooler is connected with a water softening device; the water inlet of a water storage tank is connected with municipal water supply network; the water outlet of the water storage tank is connected with the water softening device; the wind outlet of the air / oil cooler is connected with a separator; a frequency changer is connected with the air compressor; the separator is also connected with a defoaming device; the defoaming device is also connected with a drying and dehumidifying machine set; and the drying and dehumidifying machine is connected with an electric heating device. According to the invention, air temperature values and pressure values of each section are monitored in real time; efficiency of a compressor is increased completely; variable flow regulation of the compressor and a cooler blower is realized; pressure fluctuation on a tail end is reduced; compressed air separated from the outlet end of the compressor satisfies a humidity demand; in addition, the drying and dehumidifying machine set and an electric heating machine set can be cancelled so as to save energy preferably.

Description

technical field [0001] The invention relates to the technical field of air compression, in particular to an energy-saving control system for an air compressor used in large-scale industrial manufacturing. Background technique [0002] For many industries such as pharmaceuticals, electronics, and chemical fibers, air compressor systems are widely used in the fields of production technology, power transmission, and control. Generally speaking, the air is directly introduced from the outside, and after passing through the compressor, it becomes a high-temperature and high-pressure gas, and passes through an air-cooled or water-cooled cooler together with the lubricating oil to reduce part of the temperature, generally at 10-15°C, and then after separation and defoaming, Then dry and dehumidify the compressed air. In order to achieve the dehumidification effect, it needs to be lowered to a lower temperature. At the same time, in order to meet the use requirements, the last end n...

Problems solved by technology

The lower the temperature of the air entering the compressor, the higher the efficiency of the compressor, and the lower the oil cooling temperature, which significantly improves the efficiency of the compressor. In the prior art, the cooling effect of the air and oil after the compressor is not high. Reheating produces cold and hot offset phenomenon, wasting energy
