Safety feasibility analysis on the liquid organic heat transfer material heater used in the production process of bleaching powder concentrate

摘要

This paper mainly analyzed the safety feasibility of liquid organic heat transfer material heater used in the production process of bleaching powder concentrate. Firstly, inherent hazards of bleaching powder concentrate are fire and explosion and it must not be stored or transported with oils and so on, and after analyzing the whole process flow the harmful factor is dry bleaching powder concentrate dust in the workshop and drying process is the focus of safety management. Secondly, inherent hazards of liquid organic heat transfer material heater lie in fire causing by the leakage of strongly osmotic liquid organic heat transfer material. Finally, by contrasting respective characteristics, the potential hazard has been recognized and identified. Liquid organic heat transfer material heater is improper for the production process of bleaching powder concentrate, and corresponding compensated measures have also been proposed.
