Description

Technical Field

[0001] The utility model relates to an explosion-proof oil collecting device for a pool using hydraulic oil drive, belonging to the technical field of petroleum and petrochemical production equipment. Background Art

[0002] In the oil field production, gathering and transportation and sewage treatment process, there will be a lot of floating oil on the surface of the oil separator, sewage biochemical pool, waste oil pool, sewage pool (tank) and other containers. How to effectively collect and remove the floating oil from the tank and pool is an important guarantee for the smooth and effective implementation of the various process links of oil field production, injection and transportation. The floating oil on the surface of the above pools is affected by factors such as the amount of floating oil, floating oil composition, local wind direction, pool inlet and outlet locations and the installation location of the agitator. Its distribution position will be very different. It is necessary to concentrate the floating oil on the pool surface with different distribution characteristics and then collect it. The existing technology is to use manual oil booms and tank surface vehicle oil hanging methods to collect floating oil on the pool surface. Although the manual oil boom method requires less equipment investment, it is necessary to manually drag the oil boom on the edge of the pool before collecting oil each time. It is difficult to operate and has a high degree of danger. It is easy to cause secondary pollution, and it cannot be operated on the pool surface that requires a cover to collect polluted gases; the tank surface vehicle oil hanging method can achieve automatic control and high efficiency, but its disadvantages are high cost and difficulty in installation. It requires the pool structure to be a regular rectangle. When the vehicle with a large span is running, it is easy to slip on one side and cause the equipment to "run off the track", and it cannot be explosion-proof. Similarly, it cannot be operated on the pool surface that requires a cover to collect polluted gases. In order to reduce the pollution of harmful gas volatiles, the environmental protection department requires that the pools of petroleum and petrochemical production units must be equipped with a volatile gas collection system, that is, they are required to be covered; how to efficiently and automatically concentrate and collect floating oil on the pool surface is a technical problem that needs to be solved in this field, and it is suitable for collecting floating oil in the covered pool water, and the equipment is completely explosion-proof, which reduces the equipment cost.
