Background technique
Containing the impurity such as certain moisture and coal dust in coal-seam gas, current, produce CNG by coal-seam gas, before compression process generally adopts air inlet, depth of depression dehydration or the rear high-pressure deep of compression dewater, and these two kinds of dehydration ways all exist some problems, and its performance is:
Preposition depth of depression dehydration: its dewatering unit volume is large, take into the sled device space large, invest high, in running, energy consumption is high, molecular sieve and filter core short for working life, maintenance cost is high.
The dehydration of rearmounted high-pressure deep: through the inlet pressure of high pressure dewatering unit and the pressure reduction of outlet pressure restive, isobaric regeneration is difficult to realize, very easily cause the molecular sieve in high pressure dewatering unit to brush, broken, efflorescence, so that cause molecular sieve to lose efficacy, high pressure dewatering unit cannot work, and then the moisture making the molecular sieve dust containing fragmentation in CNG product and cannot remove, make CNG quality of product reach requirement.
Model utility content
The purpose of this utility model is: for the defect of prior art, a kind of compressor being applicable to coal-seam gas is provided, deep dehydrator is pressed in arranging between multi-stage cylinder series, thus more easily realize isobaric regeneration, better control inlet/outlet pressure, thus the working life extending molecular sieve and filter core, reduce the maintenance cost of compressor, raising equipment working efficiency, to overcome the deficiencies in the prior art.
the technical solution of the utility model
A kind of compressor being applicable to coal-seam gas, comprise the multi-stage cylinder series being positioned at compressor inside, multi-stage cylinder series is divided into low-pressure cylinder series and high pressure cylinder series, middle pressure-off hydrophone be arranged on low-pressure cylinder series and high pressure cylinder serial between, be together in series by pipeline one, pressure-off hydrophone outlet end during pipeline two connects also forms coordination with high pressure cylinder series.
Aforesaidly a kind ofly be applicable in the compressor of coal-seam gas, pipeline two arrange one-way valve two and stop valve two, the pipeline one between high pressure cylinder series and middle pressure-off hydrophone arranges one-way valve one and stop valve one.
Aforesaidly a kind ofly be applicable in the compressor of coal-seam gas, set gradually knock out drum, flowmeter and pressure gauge at the multi-stage cylinder series input end of compressor.
Owing to have employed technique scheme, compared with prior art, the utility model the utility model changes the Normal practice of deep natural gas dehydration in the past, change preposition depth of depression dehydration or the dehydration of rearmounted high-pressure deep into middle pressure deep dehydration, its advantage is: middle pressure deep dehydration device investment is than depth of depression dehydration plant little investment more than 10 ten thousand yuan, suitable with high pressure deep dewatering device foundation of investment, and equipment size is much less than depth of depression dehydration plant, easier layout when becoming to prize; Take the structural design of two-shipper Dual Drive, during operation, motor can be implemented step by step, and inrush current is less, and Security improves, and during device start, torque is little simultaneously, and vibrate little during operation, noise is little, and equipment runs more steady.
Accompanying drawing explanation
