兖州东方机电有限公司引进日本技术制造出烟检出装置已通过了专家技术鉴定。CYI烟检出装置是由1－2台烟感知器和1台烟感知继电器箱组成。当煤矿井下出现发烟火情时，烟浸入感知器的外离子室，烟中的微粒即被离子化了的空气吸附，室内外离子室的电压比产生变化，并由信号转换电 Yanzhou Oriental Electrical Co., Ltd. to introduce Japanese technology to create smoke detection device has passed the expert technical appraisal. CYI smoke detection device is composed of 1-2 sets of smoke sensors and a smoke sensor relay box. When a smoke fire occurs in a coal mine, the smoke dips into the outer ion chamber of the sensor and particles in the smoke are adsorbed by the ionized air. The voltage ratio of the ion chamber inside and outside the chamber changes and the signal is converted into electricity
