Steam waste heat recycling system for autoclaved aerated concrete blocks

Abstract

The invention discloses an autoclaved aerated concrete block steam waste heat recycling system, and belongs to the technical field of autoclaves, the autoclaved aerated concrete block steam waste heat recycling system comprises a main kettle body, a lining sleeve and a movable sleeve, the lining sleeve is fixedly assembled on the inner wall of the main kettle body, the movable sleeve is slidably assembled between the main kettle body and the lining sleeve, a gas guide groove is distributed in the movable sleeve, and the gas guide groove is communicated with the main kettle body. The movable sleeve is arranged between the main kettle body and the lining sleeve, a gas guide groove is formed in the movable sleeve, a gas exhaust component is arranged in the gas guide groove, the gas exhaust component comprises a plurality of rotary discs, gas guide openings are formed in the rotary discs and used for quantitatively outputting waste heat steam in the main kettle body, and the driving mechanism is used for driving the movable sleeve to directionally slide. The movable sleeve can be circularly driven to move through the driving mechanism in the cooling stage, so that waste heat steam in the main kettle body is quantitatively conveyed out of the kettle body through the exhaust component, uniform cooling of the kettle body is realized, the residual waste heat steam in the kettle body can circularly flow, and uniform dispersion of heat is ensured.

Description

Technical field [0001] The present invention belongs to the field of autoclave technology, specifically relates to an autoclaved aerated concrete block steam waste heat recovery system. Background [0002] Autoclaved aerated concrete block is a porous silicate block made of calcium material and silicon material ingredients using aluminum powder as a gas adding agent, stirred by adding water, pouring molding, inflated expansion, pre-feeding cutting, and then cured by high-pressure steam, and most of the existing autoclaving maintenance methods are maintained through autoclave kettles. [0003] Autoclave uses steam as a heat source, in fact, only the latent heat of steam is used, the saturated condensate formed by steam condensation contains a large amount of unused heat, the conventional autoclave directly emptys the kettle body after the completion of maintenance, causing the heat loss of steam, so in order to save the heat source, the autoclave needs to pour steam or exchange h...

Problems solved by technology

[0003] The autoclave uses steam as the heat source, but actually only the latent heat of the steam is used. The saturated condensate formed by steam condensation contains a lot of unused heat. Conventional steam The autoclave directly empties the autoclave body after curing, resulting in the heat loss of the steam. Therefore, in order to save heat, the autoclave ne
