Abstract

A safety environment protection buried oil storing tank is an environment protection oil storing measure that can eliminate the pollution to the soil around the tank and the underground water resource, which arranged a baffle explosion prevention material to prevent accident combustion and explosion due to naked flame, static electricity, welding, shooting, collision and wrong operation, thereby guaranteeing the essential safety of the oil storing tank. The tank is a double-wall type, and the baffle explosion prevention material is arranged in the empty cavity of the double-wall tank, simultaneously an oil leaking inspection apparatus is arranged in the empty cavity of the double-wall tank. The inspection head is connected with a signal conversion/a power amplifying controller and an alarmer by lead. The oil leaking inspection apparatus can inspect leakage and oil and gas volatilization, find and weld with oil in time, overcome effectively the seepage and leakage of the oil and gas and avoid the damage to the soil around the tank and the underground water resource. An overflow oil pond is arranged in the inlet hole of the tank to prevent oil from overflowing and caving, once found the alarmer gives an alarm to avoid oil and gas volatilization and reduce pollution to air.

Description

Safety environmental-protection buried oil tank

Technical field

The utility model relates to safety environmental-protection buried oil tank, it is a kind ofly to prevent that oiling from overflowing, prevention tank skin seepage or leakage bury the ground oil vessel.

Background technique

The storage tank that present domestic oiling (gas) is stood mostly is that employing is buried, buried oil tank is arranged on (a jar pond is generally the concrete pond) in the ground tank pond, cavity tamps with neutral fine sand or sand hill between jar pond and the tank body, the tank deck cladding thickness requires should be less than 0.5 meter, and tank body periphery filling thickness should be less than 0.9 meter (not seeing " automobile fuel filler aerating design and job specfication GB50156-2002 " for details).Fill the purpose of sandy soil in the jar pond, be to make not have air (oxygen) between jar pond and the tank body, oil, gas can not form at this and fire the space, make it have explosion-proof effect.Storage tank phenomenons such as overflowing appears in operate miss, roof fall often occur when oiling, overflowing the gasoline that comes can be absorbed by sandy soil; Because bigger with husky amount in buried tank construction, engineering difficulty height, have in installation not according to above-mentioned standard construction, just fill out a little sands in bottom, jar pond, do not fill out sand in What is more jar pond, this is very dangerous.A gas station in nearest area, Ningxia, owing to do not fill out sand in jar pond, a jar pond blast accident has taken place after running into naked light in the gasoline that overflows exactly.In addition, the discovery tank skin seepage or the leakage phenomenon that have are added jar reasons such as sinking of pond ground, cause jar watertightness barrier of bottom, pond slight crack to occur, and the gasoline medium is easy to see through tank skin tank body periphery soil and groundwater resources are caused the harm that can't save.

The model utility purpose

The purpose of this utility model is to provide a kind of safety environmental-protection buried oil tank, it can prevent phenomenon and oil storage tank skin seepage or leakages such as overflowing appears in oiling, roof fall, elimination is to the harm of tank body periphery soil and groundwater resources, eliminates the pollution to air of oil, gas.

Safety environmental-protection buried oil tank is characterized in that tank body adopts double-wall pot, is provided with block blast-proof materials in jar, has connecting tendon to be connected between jar inwall and the outer wall, and the storage tank outer wall has anticorrosive coat.Be provided with block blast-proof materials in the double-wall pot chamber, the bottom of two tank skin interlayers or top are provided with the Oil Leakage Detecting device, and probe is connected with signal conversion/power amplification controller and alarm by lead in the device.Manhole place or gauge hatch place at tank body are provided with the oil spilling pond.

Block blast-proof materials is the netted or spheroid of high-voidage structure.

Advantage of the present utility model:

1, owing to be provided with block blast-proof materials in the oil storage tank, the accident that can prevent system of Himdu logic fire, static, welding, gunslinging, collision and misoperation etc. to cause is burnt, explosive accident, guarantees the essential safety of oil storage tank.

2, this oil storage tank is the double-wall pot structure, can overcome seepage, the leakage of oil, gas effectively, avoids soil to gas station's periphery to cause serious harm and the destruction of groundwater resources.

3, in the double-wall pot chamber, be provided with the Oil Leakage Detecting device, can detect the volatilization of oil, gas, in time find, in time tank skin band oil subsidy welded.

4, the oil spilling pond that is provided with at the manhole place of tank body, phenomenons such as the oil spilling that occurs in the time of can preventing oiling, roof fall in case find, are in time taked the counter measure.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A partial enlarged drawing of Fig. 1.

1 tank body wherein, 2 dipping tubes, 3 oil filler pipes, 4 manhole covers, 5 block blast-proof materialss, 6 passages of removing contamination, 7 anticorrosive coats, 8 support saddles, 9 oil drain valves, tank skins in 10,11 outer tank skins, 12 Oil Leakage Detecting are popped one's head in, 13 Oil Leakage Detecting devices, 14 oil spilling ponds.

Embodiment

A kind of safety environmental-protection buried oil tank is horizontal tank body 1.This tank body 1 constitutes for double-wall pot, and it includes inwall 10 and outer wall 11, and inside and outside wall adopts carbon steel Q235 material, its thickness difference.Have between jar inwall and the outer wall connecting tendon be connected (accompanying drawing is for showing) constitute an integral body.Block blast-proof materials 7 is installed in tank body 1, and tank wall 11 surfaces are provided with anticorrosive coat 7.Anticorrosive coat 7 is to be coated on the outer tank skin by the pitch anti-corrosion protection layer material that the spy adds intensity level, and the employing spy who has adds the mould pitch anti-corrosion material of intensity level epoxy, and externally tank skin is implemented anti-corrosion protection.

Be provided with block blast-proof materials 7 in the storage tank 1, it is a kind of netted or spheroid of high-voidage structure.Material is a netted or spheroid of being processed into high hole by aluminium foil or other metals.This block blast-proof materials is installed in the oil storage tank, makes jar interior inflammable, explosive gaseous state, liquid hazardous chemical medium such as a gasoline etc., is running into contingencies such as static, naked light, welding, thunderbolt or faulty operation, avoids burning, blast effectively; Especially oil tank transportation truck is carrying out storage tank in the process of oiling, tends to cause electrostatic fire, burning owing to flow velocity is too fast.The storage tank of storage tank or oil tank transportation truck intercepts the transformation transformation of explosion-proof technology must carry out according to the regulation of national current standard " automobile fuel filler (gas) is stood, and light fuel and liquefied petroleum gas automobile jar require with intercepting explosion-proof technology " AQ3001-2005.
