How to set fire control system in desulfurization absorption tower of power plant

In the process of desulfurization engineering construction, many absorption towers need to be lined with anticorrosive rubber, and the rubber lining structure uses flammable materials. If there is any omission, it may cause a fire. After the construction of rubber lining of absorption tower is completed, the safety and fire prevention of absorption tower should not be careless, because fire may occur during the installation of equipment inside absorption tower and adjacent equipment around absorption tower. 1. Fire prevention measures for construction of anticorrosive rubber lining of absorption tower 1. 1. Strengthen safety management (1) The project department shall hold a special meeting on fire safety of anti-corrosion rubber lining of absorption tower, examine and approve the fire prevention scheme and safety measures of anti-corrosion rubber lining, and implement the fire prevention responsibility to units, departments and personnel. (2) The safety officer and project engineer of the project department shall provide technical disclosure, safety education and training on anti-corrosion and rubber-lined special fire safety for all construction personnel, and require all employees to sign. 1.2. The construction area should be completely closed (1). Strict closed isolation measures should be taken in the construction area with anti-corrosion lining, and entrances and exits of 1 and above should be set. Eye-catching "Lining construction is prohibited within 10 meter!" And other eye-catching warning signs. (2) Strictly implement the system of access to the rubber lining construction area, arrange special personnel to be on duty, and obtain access certificates. It is strictly forbidden to enter without a license. Anyone entering the rubber lining construction area is forbidden to carry fire and smoke. 1.3. Equipped with fire hose and fire extinguishing equipment. The fire hose is led out from the vicinity of the absorption tower, always in standby state, and equipped with fire engines if possible. Sufficient fire fighting equipment and water must be set in the absorption tower and flue. 1.4. Use explosion-proof electrical appliances for rubber lining construction. 24 V explosion-proof lamp must be used for lighting in absorption tower, and new soft rubber cable must be used for power cord. The power control switch must be explosion-proof and should be set outside the absorption tower or flue. 1.5. All openings of the absorption tower are blocked, and fire is prohibited around (1). Before the rubber lining construction of the absorption tower, the manhole, nozzle and flue gas inlet and outlet on the absorption tower must be blocked to prevent welding sparks and other kindling from falling into the absorption tower from the flue gas inlet and outlet, manhole and pipeline interface. When the absorption tower is lined with rubber, it is forbidden to use hot work within the range of 10m, and it is forbidden to use hot work near the flue gas inlet and outlet of the absorption tower. When hot work is needed, the flue inlet and outlet of the absorption tower must be tightly sealed with colored steel plates or fire-proof canvas. (2) When hot work is needed around the absorption tower 10m, the hot work ticket system must be strictly implemented, fire extinguishers, fire hoses and fire guardians should be prepared in advance, and measures should be taken before hot work can be started. 1.6. Ventilation absorption tower should be equipped with ventilation fans with sufficient capacity to ensure good ventilation in the absorption tower. 1.7. In the absorption tower, reduce the rubber and glue used for flammable rubber lining operation, and take as much as you need, generally control it at about 5 barrels, and do not pile up. 1.8. Hold fire training and set up a voluntary fire brigade. Before the construction of rubber lining, the project department will organize all employees to carry out fire-fighting training and drills, focusing on the use of fire-fighting equipment and personnel escape drills. At the same time, a volunteer fire brigade was set up. 2. Fire prevention measures after the rubber lining construction of the absorption tower After the rubber lining construction of the absorption tower is completed, we can't be careless about the safety fire prevention of the absorption tower, because in the process of installing the internal equipment of the absorption tower and the adjacent equipment around the absorption tower, fires may be caused. If the fire causes the combustion of flammable equipment such as demister and spray layer in the absorption tower, the whole project construction will be disastrous. Therefore, before the rubber lining of the absorption tower is completed and handed over for trial operation in 168 hours, the fire prevention work must be strictly done. 2. 1. Strengthening safety management (1) The safety officer and project engineer of the project department have conducted many times (long-term implementation) safety fire disclosure and safety education training for all construction personnel, and all employees are required to sign. 2.2. The construction area is completely closed (1). Strict closed isolation measures must be taken in the absorption tower area, with entrances and exits 1 or above. Eye-catching "fire zone, no hot work within 10 meter!" And other eye-catching warning signs. (2) Strictly implement the access system of absorption tower, assign special personnel to be on duty, and get in and out the vouchers. It is strictly forbidden to enter without a license. Anyone who enters the absorption tower is prohibited from carrying kindling and smoking. 2.3. Equipped with fire hose and fire extinguishing equipment. The fire hose is led out from the vicinity of the absorption tower and is always in standby state. If possible, it is equipped with fire engines. Sufficient fire fighting equipment and water must be set in the absorption tower and flue. 2.4. All openings of absorption tower shall be blocked, and fire is prohibited around (1). Manholes, nozzles and flue gas inlets and outlets on the absorption tower must be blocked to prevent welding sparks and other kindling from falling into the absorption tower from flue gas inlets and outlets, manholes and pipeline interfaces. It is forbidden to carry out hot work near the flue gas inlet and outlet of absorption tower. When hot work is needed, the flue inlet and outlet of the absorption tower must be tightly sealed with colored steel plates or fire-proof canvas. (2) When hot work is needed around the absorption tower 10m, the hot work ticket system must be strictly implemented, fire extinguishers, fire hoses and fire guardians should be prepared in advance, and measures should be taken before hot work can be started.
