Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the energy utilization rate of the existing waste heat recovery machine is low, and the waste heat recovery efficiency is low. Heat exchange can greatly improve the utilization rate of heat. At the same time, by increasing the heat exchange area between heat transfer oil and water, high-quality hot water can be obtained, so that the waste heat of the screw air compressor can be fully utilized.

Abstract

The invention discloses an effective waste heat recovery system of an air compressor. The effective waste heat recovery system comprises a waste heat recovery box, a spiral air compressor and a watertank. An oil outlet pipe, an oil return pipe, a water inlet pipe and a water outlet pipe are connected to the waste heat recovery box. An oil passing pipe is arranged in the spiral air compressor. Thetwo ends of the oil passing pipe are connected with the oil outlet pipe and the oil return pipe correspondingly. A water storage tank is arranged in the waste heat recovery box. A plurality of waterpassing pipes are connected to the upper portion of the water storage tank. The tops of all the water passing pipes communicate with one another. One water passing pipe communicates with the water outlet pipe. An isolation oil tank is arranged at the bottom in the waste heat recovery box. The bottom of the side wall of the isolation oil tank is provided with an oil inlet. The oil outlet pipe communicates with the isolation oil tank. The waste heat recovery machine and high-temperature heat conduction oil of the screw type air compressor achieve heat exchange directly, the utilization rate of heat can be increased greatly, meanwhile, the heat exchange area of the heat conduction oil and water is increased, thus high-quality hot water can be obtained, and waste heat of the screw type air compressor is fully used.

Description

technical field [0001] The invention relates to a waste heat recovery machine, in particular to an efficient waste heat recovery system of an air compressor. Background technique [0002] Heat is generated during the operation of the screw air compressor, and the electric energy actually consumed for the potential energy of the air accounts for only a small part of the total power consumption. The heat energy generated is usually directly discharged into the air through cold air , or use water-cooled methods to indirectly discharge into the natural environment through cold water pools or cooling towers, thus wasting a lot of heat and energy. Waste heat recovery machine is an important field of energy saving and environmental protection. At present, most of the existing waste heat recovery equipment adopts traditional heat exchange technology. Below 70°C, sometimes even below the temperature of domestic water, the quality and efficiency are low, which seriously affects the p...
