贵州省建材科研设计院为解决烧结砖厂现行负压干燥工艺存在的干燥效率低、设备腐蚀严重、干燥电耗高等问题,研究采用正压干燥工艺取代传统的负压干燥工艺取得成功。在对正压干燥室送热风道长度、位置、喷热口面积和出口方式、排潮口分布、排潮口面积、码坯方式等方面进行了大量的试验研究后,确定了适合于页岩、粘土等不同制砖原料的正压干燥室预热段、干燥段、冷却段的合理分布及相应的干燥工艺参数,提出了正压干燥室设计的合理结构型式,并在贵州省5个机制砖厂
In order to solve the problems of low drying efficiency, serious equipment corrosion, and high drying power consumption, the Guizhou Institute of Building Materials Research and Design Institute has solved the negative pressure drying process of the sintered brick factory. It has been successful to replace the traditional negative pressure drying process with a positive pressure drying process. After conducting a large number of experimental studies on the length, position of the hot air supply channel, the location of the spray nozzle area, the outlet method, the distribution of the outlet of the outlet, the outlet area of the outlet, and the code-sheet method in the positive-pressure drying chamber, it has been determined to be suitable for shale. The rational distribution of the preheating zone, drying zone, and cooling zone in the positive pressure drying room of the different brick materials such as clay and clay, and the corresponding drying process parameters, proposes a reasonable structural design for the positive pressure drying chamber design, and five mechanisms in Guizhou Province.
