Abstract
The utility model provides an oil tank breathing device with high efficiency, energy saving and no evaporation loss, which comprises a shell, a breather valve, a selective adsorption bed, a ventilation fence, a rain-proof cap and the like, wherein when the pressure of the oil tank is in an allowable range, the breather valve is closed; when the pressure is higher than or lower than the allowable range, the breather valve is opened, the oil tank exhales or inhales, oil gas in the exhaled air is intercepted and adsorbed by the selective adsorption bed, and only air exhales out of the tank; the air of inspiration is when selecting the adsorption bed, in getting into the jar in the lump with the oil gas under the blowback again, selects the adsorption bed inefficacy back, takes off, lets in reuse behind the hot-air regeneration, and the oil gas in the regeneration waste gas puts into the accumulator after the condensation, and it supplies to produce the hot-air usefulness not congeal the gas, the utility model discloses can reduce oil stock tank (than measures such as floating roof, breather valve in the prior art) the loss and the environmental pollution of storage capacity 1.3 ~ 4.5%.
Description
The present invention relates to the breather apparatus of oil product basin commonly used in a kind of oil refining and the petrochemical equipment, is a kind of energy-efficient free of losses new equipment.
How the existing crude oil and the storage of various oil products have the fixed tank of vent with the top cover middle part.Under the combined action of evaporation and the large and small breathing that the oil product discharge is squeezed into, temperature Change causes, a jar store oil class ceaselessly forms steam, outside vent is overflowed jar, causes boil-off loss.Particularly when a jar outer high temperature, windy, dry, when the sun directly shines, this boil-off loss is just bigger; Especially clean cargo are just even more serious.Although taked breathing valve, inner floating roof, tank body to whitewash and measure such as spray, this boil-off loss is still very big.With normal pressure oil is example, its year loss amount still account for jar the 1.3%-4.5% of storage capacity; Moreover, boil-off loss also can make oil quality reduce (can cause loss in octane number as gasoline, boil-off loss, oxidation, generation colloid, quality badness), causes serious environmental to pollute.Near the tank field people smells pernicious gas and uncomfortable feeling.
Purpose of the present invention just provides a kind of breather apparatus that does not have boil-off loss, and it can avoid the economic loss and the environmental pollution that cause because of boil-off loss with the oil gas interception and the recovery of effusion oil tank vent.
Task of the present invention is finished with following design.During expiration the oil gas of overflowing is selected the adsorbent bed of interception oil gas molecule through one and tackle, and allow air molecule see through to select adsorbent bed and overflow, when air-breathing, outside air enters adsorption bed and the oil gas molecule blowback of interception is returned in the jar.The boil-off loss of in the exhalation of tank process, just having avoided the oil gas molecule to overflow and cause like this.
Below with reference to drawings and Examples invention is done to comment further.
Accompanying drawing 1 is a kind of concrete structure sectional side elevation of the present invention.
Accompanying drawing 2 is regeneration diagram of circuits of adsorbent bed of the present invention.
Barrel-type casing ［ 6 ］ with reference to 1, one in accompanying drawing has certain mechanical strength divides three sections, two End is contraction mouth, and connection house ventilation railings suitable for reading ［ 9 ］ and rainhat ［ 10 ］, end opening are connected with the blow vent (not shown) of oil tank; The base at end opening place ［ 1 ］ is to increase the firm degree of installing. In the housing ［ 6 ］, the bottom is to distinguish that by vacuum work ［ 2 ］, pressure work distinguishes the breather valve that ［ 4 ］, sealing ring ［ 3 ］ etc. consist of; Of the present utility model be characterised in that breather valve upper/rear, namely be the selection adsorbent bed ［ 7 ］ that has netted support structure ［ 5 ］ and netted fixed structure ［ 8 ］ to be fixed in the middle and upper part. The optional adsorbent with selection interception oil gas molecule ability of selecting of filling material in the adsorbent bed ［ 7 ］ serves as. In implementation process, when the tank internal pressure was in allowed band, breather valve was closed condition, and no oil gas is overflowed; When the tank internal pressure raises, and when exceeding allowed band, ［ 4 ］ unlatching is distinguished in pressure work, and the mist of oil gas and air is by breather valve, and oil gas molecule wherein is blocked through selection adsorbent bed ［ 7 ］ time, only have at last air molecule freely to see through adsorbent bed ［ 7 ］, outside the effusion tank, the tank internal pressure descends, when being down to allowed band, pressure work distinguishes that ［ 4 ］ close, the air-flow blocking-up; When the tank internal pressure reduces, and low when following to allowed band, ［ 2 ］ unlatching is distinguished in vacuum work, the tank outer air enters through house ventilation railings ［ 9 ］, through selection adsorbent bed ［ 7 ］ time, enter in the lump in the tank with the oil gas molecule that is blocked of being blown down by Air Reverse, the tank internal pressure is gone up, vacuum work distinguishes that ［ 2 ］ close when rising to allowed band, the air-flow blocking-up. Like this, in the respiratory of oil tank, just do not have oil gas and overflow, thereby avoided the evaporation loss of oil product and the economic loss that causes therefrom and environmental pollution.
The present invention gets final product automatic operation after installing properly. Along with the prolongation of working time, select adsorbent bed gradually saturated by the oil gas molecule institute under the blowback not, at this moment, the adsorbent bed section can be taken off, regenerate.
Regenerative process is performed such. With reference to accompanying drawing 2, the adsorbent bed section ［ 4 ］ that needs regeneration is processed places between movable top lid ［ 3 ］ and movable lower cover ［ 5 ］, covers tightly, and twists good set bolt (not shown), Open valve ［ 1 ］, pass into hot-air, treat that Pressure gauge ［ 2 ］ slightly has the pressure indication, namely slowly opens valve ［ 7 ］, allow regeneration off gases enter condenser ［ 8 ］ along pipeline ［ 6 ］, the oil that condenses flows into the collecting tank (not shown) through valve ［ 9 ］, and not solidifying gas is discharged by pipeline ［ 10 ］, uses for producing hot-air. It is complete to regenerate, and shuts valve ［ 1 ］, ［ 7 ］, opens up and down lid ［ 3 ］, ［ 5 ］, and taking-up adsorbent bed section ［ 4 ］ is for subsequent use.
Effect of the present invention has realized purpose of the present invention, further is illustrated by following embodiment
Embodiment 1, after on the light diesel storage facility a kind of harmless breather apparatus of the present invention being installed, in the gas that large and small breathing is discharged, no longer included the oil gas composition.Even the breath flow does not detect the oil gas composition during up to nearly 30 the adsorbent bed volumes of per minute yet in breath.After using for a long time, when oil gas occurring in (3-4 month) breath, will select the adsorbent bed section to take off, regeneration is reused in a manner described, does not find the interception adsorption effect of oil gas is descended.
In the foregoing description, the regeneration of adsorbent beds cycle among the embodiment 1 is the longest.
The utility model is applicable to the various oil tanks of storing department such as refinery petrochemical plant and harbour tank field, comprises the common oil tank and the oil tank of inner floating roof, all can use the pollution-free technology of fuel-economizing of the present utility model to the transformation of newly-built tank field and Lao Chang tank field.
For the refinery of handling 1,000 ten thousand tons of crude oil a year, adopt present technique, can retrieve the economic loss of ten thousand tons of oil products of 4-5 at least every year, create the economic benefit of more than one hundred million units.As using in the whole nation, annual then can retrieve millions of tons oil product loss, the economic benefit of creation over ten billion Yuan is eliminated millions of tons oil product emission pollutants, has improved work situation.
