在混凝土制品生产过程中,热养护是耗时最长、耗能最高的工艺环节。通常,热养护能耗约为整个生产工艺能耗的80%。养护坑是我国沿用最久的主要混凝土养护设备之一。据不完全统计,养护坑养护的制品产量约为全部热养护制品产量的75%左右。但普通养护坑存在能耗高(平均单方蒸气耗量800公斤左右)、养护周期长(建筑构件14小时左右)、产品质量不均匀等严重缺陷。为了节约能源和提高养护坑的技术经济效益,重庆建工学院和重庆构件公司一厂联合研制成
In the production process of concrete products, thermal curing is the longest time-consuming and energy-consuming process link. In general, heat conservation energy consumption is about 80% of the energy consumption of the entire production process. Conservation pits are one of the oldest major concrete curing equipment in China. According to incomplete statistics, the production of products for conservation of conservation pits is about 75% of the total heat conservation products. However, ordinary conservation pits have serious defects such as high energy consumption (about 800 kg of average single-side steam consumption), long maintenance cycle (around 14 hours of building components), and uneven product quality. In order to save energy and improve the technical and economic benefits of the conservation pits, Chongqing Construction Engineering College and Chongqing Component Co., Ltd. jointly developed a
