Description
Technical field:
The present invention relates to industrial cutting gas, especially a kind of industrial cutting gas and mixing and filling technique thereof based on Sweet natural gas.
Background technology:
At present, the domestic market industrial cutting gas adds synergistic agent based on dissolved acetylene, propane and liquefied petroleum gas (LPG), Sweet natural gas, and dissolved acetylene accounts for about 50% of total gas consumption.And the developed countries dissolved acetylene only accounts for below 30% of total gas consumption; All the other more than 70% are that the mixing Cutting Gas of base-material substitutes by acetylene, ethene, propylene, hydrogen etc. all.As " Weir cut gas " (acetylene 70%+ propylene 30%), " match M gas is complied with in the Kazakhstan " (acetylene 85%+ propylene and ethene 15%), " match C gas is complied with in the Kazakhstan " (ethene 80%+ acetylene 20%), " this handkerchief Ztel gas " (propylene 40-50%+ divinyl 20-25%+ propine 25-30%).All there is certain defective in industrial cutting gas on the above-mentioned domestic market, as: there is the production cost height in dissolved acetylene, the energy consumption height, and seriously polluted, safety coefficient is low, and the otch dross is many, defectives such as otch local hardening; Defectives such as propane exists warm up time long, and oxygen-consumption is big; Defectives such as liquefied petroleum gas (LPG) exists flame temperature low, and impurity is many, and raffinate is many; Sweet natural gas exists calorific value low, and flame temperature is low, fills, applying pressure high defectives such as packing material cost height.
Summary of the invention:
The present invention is intended to utilize combustion of natural gas speed fast, not influenced by ambient temperature, the advantage that the propane calorific value is high, two kinds of gases are mixed in proportion, reach mutually and learn from other's strong points to offset one's weaknesses, the solution heating value of natural gas is relatively low, fill, the applying pressure height, propane is subject to envrionment temperature restriction evaporating capacity instability, combustionvelocity is slow, shortcomings such as oxygen-consumption is big, and a kind of Sweet natural gas and propane advantage of integrating is provided, in warm up time, cutting speed in feet per minute, cutting quality, aspects such as oxygen-consumption are remarkably productive, can substitute the industrial cutting gas and the mixing and filling technique thereof based on Sweet natural gas of dissolved acetylene fully.
For addressing the above problem, the present invention by the following technical solutions:
A kind of industrial cutting gas based on Sweet natural gas, adding has propane, per-cent meter by volume, Sweet natural gas accounts for 60%～90%, and propane accounts for 10%～40%; Add in addition the synergistic agent that accounts for Sweet natural gas and propane cumulative volume 0.4% is at least arranged.
Described synergistic agent is the CHEMTANE2 synergistic agent that U.S. JALAPA company produces.
The mixing and filling technique of above-mentioned industrial cutting gas based on Sweet natural gas the steps include:
A, low pressure is mixed: propane and two kinds of gases of Sweet natural gas are passed through pressure reducer separately respectively, under meter is delivered to the pipeline that is mixed and carries out being mixed of two kinds of gases, simultaneously in the pipeline that is mixed, add synergistic agent by chemicals feeder, the compressed then machine gas that will be mixed is pressed in the steel cylinder, total filling weight accounts for 20%～45% of the finished product cumulative volume, wherein, the propane amount of charging into accounts for 10%～40% of the finished product cumulative volume, the natural gas charging amount accounts for 5%～10% of the finished product cumulative volume, the synergistic agent add-on accounts for 0.4% of Sweet natural gas and propane cumulative volume in the finished product, and the low pressure stage charge pressure that is mixed is not more than 2.5Mpa;
B, high pressure replenish: natural gas liquids is forced into high-pressure carburetor and the air heat exchange is vaporized through cryopump, high pressure gas after the vaporization directly are filled in the steel cylinder, the amount of charging into accounts for 55%～80% of the finished product cumulative volume, and the high pressure phase charge pressure is not more than 10.0Mpa.
Compared with prior art, industrial cutting gas of the present invention, more safer than dissolved acetylene from its over-all properties, energy consumption is low, and cutting quality is good, economy, environmental protection can substitute dissolved acetylene fully on cutting usefulness gas.The application of this industrial cutting gas, can make acetylene at home the usage ratio in the industrial combustion gas by present being reduced to below 35% more than 50%.
Mixing and filling technique of the present invention, guaranteeing under the safe prerequisite, solved the difficult problem that two kinds of gases, synergistic agent can mix uniformly by design proportion, compared traditional CNG and fill by equal scale equipment input and reduce 50%, power consumption is saved and is surpassed 70%.
Description of drawings:
Fig. 1 is a mixing and filling technique schema of the present invention.
Embodiment:
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
It is that example illustrates its mixing and filling technique that present embodiment fills 5 cubic metres propane and Sweet natural gas with each steel cylinder, wholely fills technology as shown in Figure 1, and its divides two stages to finish, and details are as follows:
1, low pressure is mixed the stage: two kinds of gases of propane and Sweet natural gas are mixed by a certain percentage by equipment such as pressure reducer, under meters respectively, and mixed ratio draws according to the target calorific value calculation of the finished product.Chemicals feeder adds synergistic agent in proportion automatically according to the flow of under meter in the process that is mixed, and this synergistic agent is the CHEMTANE2 synergistic agent that U.S. JALAPA company produces.Under meter is transported to the chemicals feeder controller by 4 to 20 milliamperes of signals with flux values, controller can be finished computation process by preset proportion, afterwards the calculation result signal is sent to the ram pump of chemicals feeder itself, the add-on of regulating synergistic agent by the movable number of times of control ram pump.Compressing into steel cylinder by compressor after whole mixing process is finished finishes low pressure and is mixed.Total filling weight of periods of low pressure accounts for 30% of the finished product cumulative volume, promptly 1.5 cubic metres; Wherein, the propane amount of charging into accounts for 20% of the finished product cumulative volume, promptly 1 cubic metre; The natural gas charging amount accounts for 10% of the finished product cumulative volume, promptly 0.5 cubic metre; The synergistic agent add-on accounts for 0.4% of Sweet natural gas and propane cumulative volume in the finished product, promptly 0.02 cubic metre; The low pressure stage charge pressure that is mixed is not more than 2.5Mpa.
2, high pressure supplemental stages: natural gas liquids is forced into high-pressure carburetor and the air heat exchange is vaporized through cryopump, and the high pressure gas after the vaporization directly are filled in the steel cylinder, and the amount of charging into accounts for 70% of the finished product cumulative volume, promptly 3.5 cubic metres; The high pressure phase charge pressure is not more than 10.0Mpa.
In the finished product: Sweet natural gas is 4 cubic metres, accounts for 80%; Propane is 1 cubic metre, accounts for 20%; Synergistic agent is 0.02 cubic metre, accounts for 0.4% of Sweet natural gas and propane cumulative volume.
