Directional dismantling of chemical equipment

The construction environment is complex, high-altitude operations, cross-cutting operations, hoisting operations, confined space operations, hot work, scaffolding operations, electrified operations, toxic and harmful media, etc. Safety and environmental protection hazards abound. Safety and environmental protection accidents will occur if you are not careful, making the installation dismantling work quite difficult. Recently, in the dismantling project of Anqing Petrochemical's 200,000 tons/year catalytic reforming unit, the construction unit used the overall directional dumping process to successfully complete the dismantling of the unit. Compared with the traditional demolition process, the directional dumping demolition process has the advantages of less work at heights, less lifting work, and almost zero scaffolding work. It not only has high work efficiency, but also greatly reduces safety risks. The picture shows the evaporation tower and stabilization tower being dismantled in a targeted manner.
Directional pouring process, this method is also called directional blasting, which is characterized by simple construction and high success rate. The directional dumping method uses * * The explosion creates a triangular cutout in the lower part of the demolished object, causing the demolished object to dump in the direction of the cut, impact the ground and disintegrate. It is a blasting technology that throws earth and stone from a certain area to a designated area and roughly piles them into the required shape. Therefore, when implementing this technology, it is usually necessary to reserve a collapse site that is 2/3 to 3/4 greater than the building height. This solution is mainly used for dam repair (dam or tailings dam), land leveling (industrial site and farmland construction), road construction (embankment and roadbed), etc. It is relatively rare to be used for dismantling chemical equipment.
This is a more professional job :D
Yes. The dismantling of chemical equipment requires considerable organizational and professional capabilities. As all parties involved, it is necessary to establish a device dismantling management team, carefully prepare and improve the device dismantling plan, and identify, predict and explain safety and environmental risks in advance to ensure that not a single pipeline, a valve, or a cable is dismantled by mistake. On the premise of ensuring that the laboratory analysis is qualified, it is necessary to handle fire tickets, tank entry tickets, hoisting tickets, etc. for construction personnel in a timely manner and in accordance with regulations. At the same time, double on-site monitoring personnel should be arranged to provide reliable guarantee for the demolition work.
