Still kettle waste heat environment-friendly recovery equipment for autoclaved aerated concrete slab production

Abstract

The invention discloses environment-friendly still kettle waste heat recovery equipment for autoclaved aerated concrete slab production. The environment-friendly still kettle waste heat recovery equipment comprises a still kettle main body, a waste heat recovery mechanism and a gas aroma mechanism, the middle part of the upper end of the still kettle main body is connected with a pressure discharge pipe, and the pressure discharge pipe is communicated with the interior of the still kettle main body and is used for conveying high-temperature gas in the still kettle main body so as to reduce the air pressure in the still kettle main body. Through the arrangement of corresponding mechanisms, waste heat recovery can be performed on the still kettle for concrete slab production, the loss of heat in high-temperature gas in the still kettle is greatly reduced, the utilization rate of heat energy resources in the high-temperature gas released by the still kettle is greatly increased, the requirement for environment-friendly production is met, and meanwhile, the production cost is reduced. High-temperature gas can be prevented from being directly discharged into air, the probability that the temperature of air around the still kettle rises is greatly reduced, workers are prevented from being burnt, the effect of protecting the workers can be achieved to a certain extent, and potential safety hazards of production can be reduced.

Description

technical field [0001] The invention belongs to the technical field of concrete slab production equipment, and in particular relates to an environmental protection recovery equipment for waste heat of an autoclave used in the production of autoclaved aerated concrete slabs. Background technique [0002] Concrete slabs are mainly divided into two categories: reinforced concrete and prestressed concrete, and some use other reinforcement materials, such as steel wire mesh, steel fiber or other fibers. Among them, reinforced concrete slabs are slabs made of reinforced concrete materials, which are the basic structures or components in building construction and various engineering structures. They are often used as roofs, floors, platforms, walls, retaining walls, foundations, and floors. , roads, pools, etc., a wide range of applications. [0003] When the existing reinforced concrete slab is produced, an autoclave is needed. The autoclave is also called a steam-cured kettle or...
