Description

Drainage system is planted on dangerization article storage tank soil top

Technical Field

The application belongs to chemical process control pressure-bearing equipment and geotechnical engineering, and particularly relates to a drainage system for planting on the top of hazardous chemical storage tank soil.

Background

With the continuous development of economy, the energy consumed by all people in society is continuously increased, and even under the condition that the proportion of secondary energy is continuously increased, the usage amount of petroleum energy serving as traditional energy still occupies a large proportion, and the actual usage amount is extremely huge.

Since petroleum production, processing and use are in most cases not in the same area, transportation and storage is required. Because the medium in the liquefied hydrocarbon storage and transportation tank area in the petrochemical industry enterprise is inflammable and explosive, the storage tank is required to keep a certain safety distance from other buildings in relevant specifications, and in consideration of the safety of land resources and the tank area, reinforced concrete can be adopted for cast-in-place forming a tank pool, and then the liquefied hydrocarbon storage tank is placed in the tank pool, and the tank pool is filled with soil or dry sand.

The existing domestic petrochemical enterprises generally adopt an earth-covered storage tank to store the liquefied hydrocarbon under normal temperature pressurization, so that the storage safety is improved, the construction cost is reduced, the floor space is saved, the safety interval between the earth-covered storage tank and surrounding adjacent facilities is shortened, the earth-covered storage tank is slightly influenced by external fire, and the possibility and probability of generating secondary disasters are low.

However, the liquefied hydrocarbon storage tank after the soil covering is not corroded by soil media all the time. Soil is a heterogeneous multiphase system composed of three phases, solid, liquid and gas. Particularly, in rainy days, a large amount of water is soaked into the outer wall of the storage tank and is not easy to be discharged, the outer wall of the storage tank is corroded under the action of air and water in the soil, the growth of microorganisms in the soil is promoted under the combined action of the water and the air, the microorganisms participate in corrosion reaction, the corrosion of the storage tank is further aggravated,

when the corrosion action is serious, the steel tank body can be perforated, and leakage is caused, so that explosion, fire and the like are caused; in addition, since liquefied hydrocarbons need to be stored in a low-temperature environment, when the external temperature becomes high, the storage tank buried underground cannot maintain the low temperature, and molecules of the liquefied hydrocarbons become active, which is likely to cause explosion and cause large loss.

It will thus be seen that the prior art is susceptible to further improvement and enhancement.
