摘要
生活垃圾焚烧电厂的部分区域空间狭小,传统保温材料较难敷设,甚至较多异形构件表面根本无法敷设传统保温材料,导致电厂热量损失严重,能源利用效率不高,并且高温设备裸露给工作的开展带来了一定的安全隐患。针对该问题,在华中地区A生活垃圾焚烧电厂焚烧炉三角区域的支撑立柱上对3种新型保温涂料进行试验。结果表明:涂覆有机气凝胶保温涂料的立柱,表面温度下降48.66℃,节约热能90.15%;涂覆无机气凝胶保温涂料的立柱,表面温度下降45.69℃,节约热能87.04%;涂覆陶瓷微珠纳米保温涂料的立柱,表面温度下降44.66℃,节约热能83.38%;可知有机气凝胶保温涂料保温效果最好,无机气凝胶保温涂料和陶瓷微珠保温涂料保温效果稍差,但同样表现良好。该次试验可为整个行业的高效节能发展及恶劣区域中的保温材料选择提供一定的借鉴。
In some areas of the domestic waste incineration power plant,the space is small,so the traditional thermal insulation materials are more difficult to lay,and even the surface of more special-shaped components cannot be laid with traditional insulation materials at all,resulting in serious heat loss and low energy utilization efficiency in the power plant,and the exposed high-temperature equipment has brought certain safety hazards to the development of the work.In order to solve this problem,three new thermal insulation coatings were tested on the support column in the incinerator triangle area of domestic waste incineration power plant A in central China.The results showed that the surface temperature of the column coated with ethyl orthosilicate aerogel insulation coating decreased by 48.66℃,saving 90.15%of heat energy;the surface temperature of the column coated with sodium silicate aerogel insulation coating decreased by 45.69℃,saving 87.04%of heat energy;the surface temperature of the column coated with ceramic microbead nano thermal insulation coating decreased by 44.66℃,saving 83.38%of heat energy;it can be known that ethyl orthosilicate aerogel insulation coating has the best thermal insulation effect,sodium silicate aerogel insulation coating and ceramic microbead insulation coating have slightly worse thermal insulation effect,but are also of good performance.The test can provide some reference for the high-efficiency and energy-saving development of the whole industry and thermal insulation material selection in harsh areas.
