Abstract

The invention discloses a composite heat recovery system of an oil-free screw air compressor, comprising an oil-free screw air compressor and a PLC controller, wherein the oil-free screw air compressor exchanges heat with a first air heat exchanger and a second air respectively The device is connected with the adsorption air dryer, the first air heat exchanger and the second air heat exchanger are both connected with the circulating water tank, and the oil-free screw air compressor is also connected with a cooling tower. The compound heat recovery system of the oil-free screw air compressor of the present invention, the first air transducer and the second air transducer are arranged outside the oil-free screw air compressor, and the circulation operation of the cooling water heat recovery system is controlled by the PLC controller Switching with the cooling tower system solves the problem that the heat generated during the working process of the existing oil-free screw air compressor cannot be recycled. The primary energy consumption required by water has the advantages of high efficiency, energy saving, and environmental protection, and is of great significance to sustainable development.

Description

technical field [0001] The invention belongs to the technical field of heat recovery of air compressors, and in particular relates to a composite heat recovery system of an oil-free screw air compressor. Background technique [0002] Compressed air, as an important power source, has the advantages of convenient storage and transportation, no pollution and inexhaustible free air as raw material, and is widely used in various links and places that require compressed air production technology. In the process of producing compressed air by the air compressor, a large amount of heat (equivalent to about 85% of the input electric energy) will be generated. At present, the heat of the air compressor is generally discharged to the environment through air cooling or water cooling. , resulting in a great waste of energy and thermal pollution of the environment. [0003] In most production-oriented enterprises, the energy consumption of air compressors accounts for about 10% to 35% of...
