Description
Technical Field
[0001] This utility model relates to the field of oil and gas storage and transportation experimental technology, and in particular to an environmentally friendly internal floating disk combustion device. Background Technology
[0002] Internal floating roof tanks offer advantages such as reduced evaporation of the medium, lower air pollution and fire risk, and extended tank lifespan. They play a crucial role in the storage and transportation of highly volatile, low-flash-point, and high-quality refined oil products and hazardous chemicals (such as methyl ethyl ketone). For fire protection, the internal floating roof serves as a fire safety barrier within the tank structure, reducing the concentration of flammable gases above the floating roof and preventing contact between flammable liquids below and small ignition sources. However, the new structure combining an external dome with an internal floating roof also presents problems. Inadequate sealing of the floating roof, adhesion to the tank wall due to liquid level drops, and gaps between the liquid level and the floating roof result in oil and gas formation that does not rapidly exceed the explosive limit and saturate as in a dome-roof tank, nor does it dissipate as quickly as in an external floating roof tank. It easily rises to the explosive limit, becoming a contributing factor to petrochemical fires and explosions and providing energy support. Therefore, management and fire safety departments are increasingly focusing on the impact of the internal floating roof structure and materials on fire resistance. Many manufacturers are actively conducting fire resistance tests on their internal floating roofs to meet bidding requirements. However, internal floating roof fire resistance tests often use petroleum, diesel, alcohol, etc. as fuel media, which are characterized by high smoke production, dense black smoke, and high toxicity. Given the increasingly stringent environmental protection requirements, such experiments are becoming increasingly difficult to conduct.
[0003] Traditional internal floating disk combustion devices often produce large amounts of toxic black smoke during combustion, causing serious environmental pollution and potentially threatening the health of experimental personnel. Furthermore, the high temperatures generated during combustion can damage surrounding experimental equipment and protective facilities, affecting the accuracy of experimental results. In addition, traditional internal floating disk combustion devices suffer from low fire extinguishing efficiency and complex operation, failing to fully meet environmental protection and experimental requirements.
[0004] Therefore, an environmentally friendly internal floating disk combustion device is proposed. Utility Model Content
