Description
Technical field
The present invention relates to motive power machine equipment pressure regulation air feeder technical field, be specifically related to a kind of fuel oil-rock gas mixed power machinery movable and skid-mounted formula associated gas (or CNG) regulator that is used for.
Background technique
Along with the variation of China's energy resource structure and continuing to increase of environmental protection dynamics, make the development and utilization of rock gas obtain swift and violent development.The present domestic fuel oil-rock gas mixed power system of having developed; Existing diesel engine also can carry out diesel oil, the transformation of rock gas mixing double fuel, and improvement project needs cover associated gas (or CNG) regulator to come to provide for the oil gas hybrid system natural air-air source of pressure and stable components.
Tradition regulator (supposing three grades of pressure regulation) working principle is: at first be connected with skid CNG tank car with quick release coupling with high pressure hose; Compressed natural gas is imported first-class heat exchanger; And in first-class heat exchanger, gas is heated, after the decompression of one-level pressure governor, again through secondary heat exchanger heating and the pressure regulation of secondary pressure governor; Measure after meeting through three grades of pressure regulation once more afterwards, finally supply with gas consuming device with the gas process conditions.The shortcoming of this regulator is: all need set up before the I and II pressure regulation cover heat exchange system (comprising heat exchanger, boiler and control unit) to rock gas heat (purpose be in case in the decompression process a large amount of heats of gas expansion absorption cause pipeline ice stifled; Influence system's proper functioning); And setting up of heat-exchange system makes device technique complicated; Bulky, simultaneously fund input is improved accordingly, and not have the separation buffer device; Only can can't satisfy the clean inadequately usage requirement of associated gas as the usefulness of the clean gas pressure regulation in the CNG tank car.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple, practical, movable and skid-mounted formula associated gas regulator of being easy to observe.
Technical problem to be solved by this invention adopts following technological scheme to realize:
A kind of movable and skid-mounted formula associated gas regulator; Comprise a sled piece; Said sled piece is provided with main line, and said main line one end unloads the gas flexible pipe through the high pressure that the air inlet quick release coupling connects the associated gas tank car, and the said main line the other end is provided with air taking port; It is characterized in that: be positioned at air inlet quick release coupling downstream on the said main line and be provided with big pressure reduction and do not have the stifled pressure regulator valve of ice; Said big pressure reduction does not have the stifled pressure regulator valve downstream of ice and is provided with the self-balancing type pressure governor, and said self-balancing type pressure governor downstream are provided with the first-level buffer separator, and said first-level buffer separator downstream are provided with flowmeter; Said flowmeter downstream are provided with axial flow pressure regulator, and said axial flow pressure regulator downstream are provided with the level 2 buffering separator.
Be connected with blow-off line between said first-level buffer separator and the level 2 buffering separator.
Be equipped with safety valve on said first-level buffer separator and the level 2 buffering separator.
Said air inlet quick release coupling and big pressure reduction do not have and are positioned at main line between the stifled pressure regulator valve of ice and are provided with ball valve.
Be positioned at air inlet quick release coupling and first-level buffer separator on the said main line and be provided with I and II siphunculus road.
The invention has the beneficial effects as follows: the present invention compares with conventional art; Can save two cover heat exchange systems, gas heating does not have at big pressure reduction that the stifled pressure regulator valve of ice is inner to be accomplished automatically, and the reasonable distribution through each stage pressure; Can control in the later decompression process of secondary and need not gas is heated once more; Also can guarantee that temperature drop can not cause ice stifled, the equipment using scope is more extensive simultaneously, can satisfy the usage requirement of multiple different makings.
