AI Technical Summary

Technical Problem

Existing compressed air energy storage equipment lacks an efficient and uniform descaling structure suitable for the air storage tank. Manual cleaning is difficult and time-consuming, affecting the service life and operating efficiency of the equipment.

Method used

A descaling device was designed, including a cover plate, a connecting plate, a lifting plate, and a scraper. The device achieves uniform cleaning of the inner wall of the gas storage tank through rotation and lifting movements. Combined with a waste heat recovery mechanism, the scraper is driven to move up and down by a hydraulic rod, and the cleaning range is expanded by a rotating rod. Waste heat from the exhaust pipe is recovered by using a heat-absorbing copper pipe and a circulating water pump.

Benefits of technology

It achieves efficient and uniform descaling of the inner wall of the gas storage tank, reduces the difficulty and time of operation, improves the operating efficiency and life of the equipment, and recovers the waste heat of the exhaust pipe, reducing energy loss and increasing energy utilization efficiency.

Abstract

The application provides a descaling device and compressed air energy storage equipment, and relates to the technical field of compressed air energy storage. A user places a cover plate on the top of a gas storage tank, so that a positioning frame and a scraper plate are deeply inserted into the gas storage tank, a spring rebounds, so that the scraper plate is in contact with the inner wall of the gas storage tank. At this time, the user drives the lifting plate to move up and down, so that the scraper plate moves up and down to clean the dirt on the inner wall of the gas storage tank. Meanwhile, the user drives the connecting plate to rotate relative to the cover plate along the axis direction of the connecting plate, so that the scraper plate can rotate, the cleaning range of the inner wall is wider, the scraper plate can sufficiently and uniformly perform the descaling work on the inner wall of the gas storage tank, and the descaling effect is better. The technical problem that the existing technology lacks an efficient and uniform descaling structure suitable for the gas storage tank of the energy storage equipment and manual cleaning is difficult to operate and time-consuming is solved.
