Description
Technical field:
The utility model relates to a kind of catalyzer filing provision, relates in particular to a kind of compressed natural gas catalyst aid adding set
Background technique:
With other energy ratios, rock gas has many advantages.And the rock gas that uses has all passed through desulfurization, drying, has added processing such as smelly, therefore safer, the more environmental protection of use in combustion process.But rock gas needs line transportation, so the construction of conveyance conduit has limited gas utilization scale and the continuous expansion that utilizes the field.The boiling point of rock gas is lower, is not subjected to the influence of ambient temperature, does not have the gasification problem.But heating value of natural gas is lower, and the combustion gas utilization ratio is also lower.
The model utility content:
The purpose of this utility model is to provide a kind of is not having natural-gas transfer pipeline, or the compressed natural gas catalyst aid adding set that can move is as required used in the impaired place of natural-gas transfer pipeline everywhere.
The utility model is implemented by following technological scheme: compressed natural gas catalyst aid adding set, it comprises decompressor and adding set, described decompressor comprises heat exchanger, a heat exchanging tube, the secondary heat exchange pipe, reduction valve and secondary reduction valve, a described heat exchanging tube and described secondary heat exchange pipe are installed in the described heat exchanger, the air outlet of a described heat exchanging tube is communicated with the suction port of a described reduction valve, the air outlet of a described reduction valve is communicated with the suction port of described secondary heat exchange pipe, the air outlet of described secondary heat exchange pipe is communicated with the suction port of described secondary reduction valve, and the air outlet of described secondary reduction valve is communicated with the flowmeter suction port of described adding set; Described adding set comprises additive storage tank, metering pump, described flowmeter, atomizer and PLC controller, is provided with described metering pump on the air outlet of described additive storage tank; The air outlet of described flowmeter and described metering pump is connected with the suction port of described atomizer respectively; The signal output part of described flowmeter is connected with the signal input part of described PLC controller, and the signal output part of described PLC controller is connected with the control input end of described metering pump.
Advantage of the present utility model: can move everywhere as required, there be not natural-gas transfer pipeline, or use in the impaired place of natural-gas transfer pipeline, the additive feeding quantity is regulated in variation according to gas flow automatically, solved in the natural gas transmission ﹠ distribution quantitatively, accurately, the technical requirements that is mixed automatically, improved heating value of natural gas, strengthened the combustion gas utilization ratio, make natural gas replace traditional acetylene gas, use as industrial combustion gas.
