1 Wet quenching should comply with the following regulations: a. Protective railings should be installed around the powder coke sedimentation tank, and the ditch should have a cover. ； b. The cooling platform should be equipped with water pipes ； c. It is prohibited to use phenol water coke quenching without secondary (biological) treatment ； d. The driver's cab of the powder coke grab bucket should be located on the side. 2 Dry quenching should comply with the following regulations: a. The dry quenching device must ensure the tightness of the entire system. System air tightness tests should be conducted before putting into production and after overhaul. ； b. The design, manufacturing, construction and acceptance of waste heat boilers and their accessories shall comply with the provisions of the "Steam Boiler Safety Technical Supervision Regulations" ； c. The outside of the dry quenching furnace discharge device should be well ventilated, and the coke transport belt corridor should be equipped with a carbon monoxide detection and alarm device. ； d. At the highest point of the dry quenching device, a wind direction meter and anemometer should be installed. When the wind speed is greater than 20m/s, the crane should stop operating. Fixing devices should be provided at both ends of the crane track ； e. The traverse traction device, hoist and loading device should be equipped with limit and position detection devices ； f. The primary dust collector, boiler outlet and the upper part of the secondary dust collector of the inert gas circulation system should be equipped with explosion-proof devices ； g. The dry coke quenching device should be equipped with an automatic analyzer for circulating gas components to analyze and record the carbon monoxide, hydrogen and oxygen contents. ； h. Before entering the dry quenching furnace and circulation system for inspection or operation, the isotope ray source shutter should be closed to perform gas replacement and gas composition detection in the system. Only when the carbon monoxide concentration is below 50 ppm and the oxygen content is greater than 18% can you enter. When entering, you should bring detection instruments and communication tools for external communication. ； i. Relief valves should be installed at dead ends such as the top of the secondary dust collector. ； j. When inspecting the discharge device during operation, a gas mask should be worn ； k. It is strictly prohibited to stay near explosion-proof holes and circulating gas release ports. This post was last edited by ryn on 2009-3-15 15:41 ]
