摘要:
为解决湿度过大造成的矿山呼吸性粉尘浓度检测结果偏大甚至检测设备损坏等问题,提出了一种矿山呼吸性粉尘浓度检测除湿系统。该系统以半导体制冷为原理,选择XH-C1210作为制冷器件,设计了散热方式及排水系统,给出了系统的软件流程。系统采用水冷法提高热交换效率,通过除湿后净气对高湿含尘气流进行稀释干燥减少颗粒损失。实验结果显示,对高湿度的含尘气流,当气流温度在24 ℃以下时,均可使湿度降至60%RH以下,入口温度越低,除湿效果越明显;使用激光粉尘浓度仪进行测试发现,使用该除湿系统可有效避免高湿环境下粉尘浓度测试结果偏大的情况。
Abstract:
In order to solve the larger detection result of mining respirable dust concentration and detection equipment damage caused by high humidity, a mine breathing dust concentration detection dehumidification system was proposed. Based on the principle of semiconductor refrigeration, XH-C1210 was selected as the refrigeration device, heat dissipation method and drainage system were designed, and the software flow of the system was put?forward. The system adopted the water cooling method to improve the heat exchange efficiency, and the dry and clean air after cooling were used to dilute and dry the high-humidity dust-containing gas stream to reduce the particle loss. The experimental results show that when the airflow temperature of high-humidity dusty airflow is below 24 ℃, the humidity can be reduced to below 60%RH. The lower the inlet temperature, the more obvious the dehumidification effect. the test is found using a laser dust concentration meter. The dehumidification system can effectively avoid the situation that the dust concentration test result is too large in high humidity environment.
