Abstract
The present invention relates to an inflammable gas with high fuel value, and is characterized by that said inflammable gas is a saturated vapor produced by pressing liquefied petroleum gas into light oil, and the main component of said light oil is the mixture of C4-C8 paraffins. Said invention possesses the advantages of large heating powder, high flame temp., safe use and low cost, etc..
Description
The present invention relates to inflammable gas, refer in particular to a kind of inflammable gas of high burning-value.
Usually the inflammable gas that uses of gas welding or gas cutting is divided into two classes substantially, and the first kind is an acetylene gas, and its thermal value is big, and flame temperature height, rate of heating are fast, and major defect is: make the calcium carbide that acetylene gas uses and will consume a large amount of electric power, cost is higher; And itself blasts acetylene easily, uses more dangerous.Second class is a liquefied petroleum gas (LPG), and its cost is low, and is easy to use, and major defect is: warm up time is longer, and flame temperature is lower, and oxygen consumed tolerance is bigger.
The object of the present invention is to provide a kind of inflammable gas of high burning-value, by liquefied petroleum gas (LPG) is pressed into C
4-C
8In the alkane blended lightweight oil, obtain the saturated vapo(u)r of this lightweight oil, reach that thermal value is big, flame temperature is high, the safe in utilization and low purpose of holding concurrently of cost.
The object of the present invention is achieved like this: a kind of inflammable gas of high burning-value, it is characterized in that this inflammable gas is that liquefied petroleum gas (LPG) is pressed into the saturated vapo(u)r that produces in the lightweight oil, and the major ingredient of this lightweight oil is C
4-C
8The mixture of alkane.
The boiling point of this lightweight oil is 1-110 ℃.
The boiling point of this lightweight oil is preferably 1-75 ℃.
The major ingredient of this lightweight oil and proportioning are (parts by weight): pentane 50-98, butane 0-30, ethane 0-40, heptane 0-30, octane 0-30.
Major advantage of the present invention is:
1, the lightweight oil that uses among the present invention has the advantages that thermal content is higher than liquefied petroleum gas (LPG), lightweight oil thermal content of the present invention after tested is 12500-14000 kilocalorie/kilogram, and the thermal content of liquefied petroleum gas (LPG) is 9200-10000 kilocalorie/kilogram, therefore, inflammable gas of the present invention has advantages such as high burning-value, thermal value is big, flame temperature is high, rate of heating is fast.
2, the present invention is based on the dead meal crude pentane of petroleum chemicals, cooperates suitable heptane and octane to be deployed into boiling point 1-110 ℃ lightweight oil, solved the problem of utilizing of petroleum chemicals dead meals.Because the dead meal crude pentane is industrial organic solvents such as being used to refine pure pentane, iso-pentane, pure hexane or isohexane is on a small quantity only arranged, and major part is fallen for burn processing, technical scheme of the present invention turns waste into wealth a large amount of dead meal crude pentanes.
3, the major ingredient of lightweight oil of the present invention is: pentane, butane, hexane, and heptane and octane, it does not have toxicity, but perfect combustion generates CO
2, there are not problems such as leakage, incomplete combustion and poisoning, be a kind of efficient, safe liquid fuel, its saturated vapo(u)r is the inflammable gas of high burning-value.
4, the using method of inflammable gas of the present invention is very simple, only needs liquefied petroleum gas (LPG) is injected lightweight oil, makes its gasification, it because of its proportion 0.68 times of air, so can combine volatilization with liquefied petroleum gas (LPG),, have advantage easy to use, safe by escape pipe output burning.
The present invention is further described below in conjunction with preferred embodiment and accompanying drawing:
Fig. 1 is that inflammable gas of the present invention generates synoptic diagram;
Inflammable gas of the present invention is to utilize the dead meal crude pentane of petroleum chemicals to cooperate heptane or octane to be deployed into the saturated vapo(u)r of boiling point for 1-110 ℃ lightweight oil generation, because the major ingredient of crude pentane is pentane, butane and hexane; Wherein butane has a kind of isomer, and its boiling point is-0.5--12 ℃, pentane has two kinds of isomer, and its boiling point is 9.5-36 ℃, and hexane has four kinds of isomer, and its boiling point is 49.7-68 ℃, consults table 1.
The structural formula of the crude pentane of table 1 usefulness of the present invention and boiling point:
Because in the dead meal crude pentane, the composition of its contained butane, pentane and hexane is unfixed, so its boiling point is unfixing yet, so must add heptane and/or octane, the allotment boiling point is 1-110 ℃ a lightweight oil, so that have enough saturated volatilizations to press and enough saturated vapo(u)r oleaginousness when using.If boiling point is too high, then press not enoughly because of saturated volatilization, make the oily quantity not sufficient of steam, if boiling point is too low, fuel value does not reach requirement, and in time spent not, has the liquid fuel volatilization, causes waste.
From a large amount of evidences, major ingredient and proportioning best in the lightweight oil of the present invention are (parts by weight):
Pentane 50-98, butane 0-30, hexane 0-40, heptane 0-30, octane 0-30.
Usually contain the impurity below 5% in the crude pentane, do not influence its combustionproperty.
Table 2 has exemplified the influence of the proportioning variation of lightweight oil of the present invention to boiling point:
The different proportionings of table 2 lightweight oil are to the influence of boiling point:
| Test number | Butane (gram) | Pentane (gram) | Hexane (gram) | Heptane (gram) | Octane (gram) | Impurity | Boiling point ℃ |
| ????1 | ????10 | ????70 | ????- | ????20 | ????- | Below 1% | ????30 |
| ????2 | ????5 | ????80 | ????- | ????- | ????15 | Below 1% | ????40 |
| ????3 | ????2 | ????68 | ????- | ????10 | ????10 | Below 1% | ????45 |
| ????4 | ????50 | ????30 | ????- | ????20 | Below 1% | ????60 | |
| ????5 | ????3 | ????62 | ????5 | ????15 | ????15 | Below 1% | ????65 |
Certain also proportioning of adjustable each composition reaches required various boiling point requirements, and its way is that an amount of heptane and/or octane are joined in the crude pentane, and making its boiling point is 1-110 ℃, and optimizing boiling point is 1-75 ℃.
Consult Fig. 1, lightweight oil 16 of the present invention is stored in the staving 14, and these staving 14 interpolations set out mouthful near the bucket pneumatic tube 12 at the end, installing intake valve 13 and be communicated with liquefied petroleum jar 10 on this pneumatic tube 12.Air outlet, top 18 at staving 14 is communicated with escape pipe 20.During use, open intake valve 13, liquefied petroleum gas (LPG) enters in the staving 14 from pneumatic tube 12, in lightweight oil 16, generate bubble 70 and go out liquid level 40, form the saturated vapo(u)r 30 of lightweight oil 16 on the top of staving 14, the saturated vapo(u)r 30 that contains lightweight oil 16 is sent into the burner (not shown) from escape pipe 20.
The inflammable gas of high burning-value of the present invention has the acetylene gas commonly used and the advantage of liquefied petroleum gas (LPG) concurrently, overcome the defective of its existence, be a kind of high burning-value that has, be applicable to the new forms of energy of gas welding, cutting, and also have advantages such as easy to use, that burning is complete, nontoxic, safe.
