[0004] In the prior art, for double-layer multi-compartment skid-mounted refueling tanks, after a certain period of use, water and solid impurities will remain at the bottom of the refueling tanks. If they are not discharged in time, they will gradually accumulate. The quality of the oil in the refueling tank will also have a certain impact

Embodiment Construction
[0015] The content of the present invention will be further described below in conjunction with accompanying drawing:
[0016] Such as figure 1 Shown is a schematic diagram of a sewage discharge device for a double-layer multi-compartment skid-mounted refueling tank, including a large oil storage tank, a tank base 1, a small oil storage tank 3, an arc-shaped baffle 2 and a sewage outlet 7.
[0017] The large oil storage tank 5 is installed on the tank base 1, and two small oil storage tanks 3 are arranged inside the large oil storage tank 5, and the two small oil storage tanks 3 are small standard oil storage tanks with cylindrical oval heads. And between the two small oil storage tanks 3, a compartment plate 6 is arranged, and the arc-shaped surface of each small oil storage tank 3 is close to the middle compartment plate 6, and the compartment plate 6 can be a fully enclosed plate, It is also possible to evenly open a plurality of holes in the compartment plate 6, and the s...

The invention discloses a blowdown apparatus of a skid-mounted oil feeding tank with double layers and multiply storehouses and belongs to the field of oil product warehousing. The blowdown apparatus mainly comprises a large-sized oil storage tank and small-sized oil storage tanks, wherein a plurality of standard ellipse-shaped small-sized oil storage tanks are arranged in the large-sized oil storage tank; a warehouse separating board is arranged between two adjacent small-sized oil storage tanks for separating the two small-sized oil storage tanks; an arc-shaped baffle board is arranged at bottom of an inner chamber of each small-sized oil storage tank; the arc-shaped baffle boards are grid-shaped; a stainless steel filter screen with approximate 80 meshes is laid on the surface of each arc-shaped baffle board; a sewage outlet is formed in one side of bottom of each small-sized oil storage tank; the sewage outlets penetrate through a steel protective layer and extend to the outer part of large-sized oil storage tank. The blowdown apparatus has the advantages that impurities in small-sized oil storage tanks are subsided at tank bottom, the arc-shaped baffle boards are adopted to separate explosion-proof material from impurities, the explosion-proof material discharged with the impurities is avoided, so that the waste of explosion-proof material resource is avoided, meanwhile, and the stoppage of sewage outlets caused by explosion-proof material discharged with the impurities is avoided, and the blowdown apparatus is safe, reliable and convenient to maintain and clean.
Description
technical field [0001] The invention relates to an oil storage tank in the field of oil product storage, in particular to a sewage discharge device with double-layer multi-compartment skid-mounted refueling tanks. Background technique [0002] The oil storage tank is a container for storing oil products, and it is the main equipment of the oil depot. According to the material, oil storage tanks can be divided into metal oil tanks and non-metal oil tanks; according to their location, they can be divided into underground oil tanks, semi-underground oil tanks and above-ground oil tanks; according to the installation form, they can be divided into vertical and horizontal; according to their shape, they can be divided into Cylindrical, square box and spherical. [0003] Horizontal cylindrical oil tanks are widely used. Because it has the ability to withstand higher positive and negative pressures, it is beneficial to reduce the evaporation loss of oil products, and also reduces...
