Energy storage device for air compressor waste heat reuse

Abstract

The invention discloses an energy storage device for air compressor waste heat reuse and relates to an air compressor technology. The energy storage device mainly comprises an air compressor room formounting an air compressor, and the air compressor room is internally provided with a cooling device connected with the air compressor. A hot water absorbing tank and a water pump are arranged at thetop of the air compressor room, and the air compressor room is internally provided with a heat energy converting mechanism which comprises a support, a cylinder body arranged on the support, and a piston arranged in the cylinder body and capable of sliding. A rotary shaft is fixed to the middle of the cylinder body and rotatably connected with the support, and the interior of the cylinder body isdivided into a first cavity body and a second cavity body through the piston. The first cavity body and the second cavity body are internally provided with expanding agents correspondingly, and the expanding agents are liquid which achieves thermal expansion. A water inlet is formed in the upper portion of the hot water absorbing tank, and a water outlet is formed in the bottom of the hot water absorbing tank. The water outlet is connected with the water pump, and the cylinder body drives the water pump to operate when rotating along the rotary shaft. Waste heat generated by the air compressoris absorbed and stored through the hot water absorbing tank, and the hot water absorbing tank can serve as a water source for washing of workers in a plant area.

Description

technical field [0001] The invention relates to air compressor technology, in particular to an energy storage device used for recycling waste heat of an air compressor. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane or rotary screw. [0003] Air compressors can be widely used in mining, machinery manufacturing, construction, textile, petrochemical and other places that need to compress gas. The existing air compressor system mainly includes an air compressor, an oil-air separator and an oil cooler. During operation, the circulating cooling lubricating oil in the air compressor enters the oil cooler after passing through the oil-air separator, and is cooled by the oil cooler. Then it is recycled back into the air compressor. During the entire operation of the air compressor, about 90% of the input electric energy is conve...

Problems solved by technology

The existing air compressor system mainly includes an air compressor, an oil-air separator and an oil cooler. During operation, the circulating cooling lubricating oil in the air compressor enters the oil cooler after passing through the oil-air separator, and is cooled by the oil cooler. Then it is recycled back into the air compressor. During the entire operation of the air compressor, about 90% of the input electric energy is converted into heat energy, and more than 70% of the heat energy is directly brought to the oil cooler by the circulating cooling lubricating oil. In the oil cooler, it exchanges heat with the cooling medium to dissipate it. In this process, a large amount of heat energy is not effectively utilized, resulting in waste and failing to meet the energy saving requirements.
