Description

Technical Field

[0001] This utility model relates to the field of concrete slab technology, specifically to a steam waste heat recovery and utilization device for the production of autoclaved aerated concrete slabs. Background Technology

[0002] Concrete slabs are lightweight, porous building materials made from cement, lime, gypsum, aluminum powder, and water through a series of processes. They possess advantages such as light weight, thermal insulation, good fire resistance, and high workability, and are widely used in building walls, roof panels, floors, and sound insulation panels. The production of autoclaved aerated concrete (AAC) slabs generates a significant amount of waste heat. This device aims to efficiently recover this waste heat to improve energy utilization and reduce energy consumption.

[0003] According to patent document CN222494779U, a steam waste heat recovery and utilization device for the production of autoclaved aerated concrete slabs is disclosed, belonging to the field of steam waste heat recovery technology. It includes an autoclave, a support frame placed on one side of the autoclave, a gas storage tank fixedly installed on the top of the support frame, a discharge pipe fixedly installed on the top of the autoclave, an insulated conveying pipe fixedly connected to the top of the discharge pipe, a connecting pipe fixedly installed on the top of the gas storage tank, the end of the insulated conveying pipe away from the discharge pipe being fixedly connected to the connecting pipe, a cold water pipe fixedly installed inside the gas storage tank, the inlet end of the cold water pipe passing through the top of the side wall of the gas storage tank, and the outlet end of the cold water pipe passing through the bottom of the gas storage tank and a water supply pipe fixedly installed thereon, the side of the water supply pipe away from the gas storage tank being fixedly installed at the bottom of the autoclave.
