Description
Technical field
The invention discloses a kind of cleaning equipment of natural gas Primordial Qi, specifically a kind of natural gas filter.
Background technology
Due to technical measures such as supercharging exploitations, exploit in the natural gas Primordial Qi obtained and have a large amount of solid, liquid impurity, these impurity determine Primordial Qi directly can not flow to terminal use, and the natural gas namely flowing to terminal use must through removal of impurities filtration treatment.
At present, common natural gas filter is monomer operation, namely on the feed-line of natural gas Primordial Qi, only arranges a filter mechanism in a series arrangement.This filter type not only filtration yield is limited; and because of the cleaned at regular intervals of filter mechanism and unscheduled maintenance etc., need often to carry out " shutdown " to feed-line, this has had a strong impact on the purification conveying capacity of natural gas Primordial Qi; add the operation cost of natural gas transport enterprise, very impracticable.
In addition, natural gas filtering mechanism is formed primarily of cylindrical shell and the filter core be assemblied in cylindrical shell, and common filter core is screen cloth, and it is reliable that this filter core is used for filtering solid contaminants.But, exploit the natural gas Primordial Qi obtained to be carried up by boost fluid, namely liquid gas is mixing one, aforementioned filter core cannot make the gas-liquid separation in Primordial Qi effectively, need to purchase separately and the essence filter equipment-separator being series at filter mechanism rear portion carries out gas-liquid separation in Primordial Qi (certainly, also need to remove fine-particle solid impurity), the cleaning mode of this smart filter equipment that Primordial Qi gas-liquid separation is placed one's entire reliance upon, the loss of smart filter equipment will certainly be increased, and then increase natural gas cleaning cost, and the gas-liquid separation of Primordial Qi is only carried out by smart filter equipment, can not reliably realize thorough separation, portion of natural gas is caused to be misprinted waste.
Summary of the invention
The object of the invention is to: for above-mentioned the deficiencies in the prior art, a kind of redundancy running is provided, effectively can make solid, liquid, gas reliable separation in natural gas Primordial Qi, reduce the natural gas filter of cleaning cost.
The technical solution used in the present invention is: a kind of natural gas filter, and comprise the first identical filter mechanism of structure and the second filter mechanism, described filter also includes shunt conduit and bus dump; The two ends correspondence of described shunt conduit is connected to the first axial arranged filter mechanism and the front portion of the second filter mechanism, shunt conduit is provided with the air inlet of Primordial Qi, and the shunt conduit be provided with between the first stop valve and the second filter mechanism of the shunt conduit between this air inlet and the first filter mechanism is provided with the second stop valve; The two ends correspondence of described bus dump is connected to the rear portion of the first filter mechanism and the second filter mechanism, bus dump is provided with the gas outlet of purified gas, and the bus dump be provided with between the 3rd stop valve and the second filter mechanism of the bus dump between this gas outlet and the first filter mechanism is provided with the 4th stop valve.
Described filter mechanism is formed primarily of cylindrical shell, sparger and separator, the front end of described cylindrical shell is connected with three-way body, this three-way body is connected with flap type and shunt conduit respectively, the rear end of cylindrical shell is direct or be connected with bus dump by transition conduit, described sparger is axially inserted in cylindrical shell through flap type and three-way body, described separator is assemblied in the cylindrical shell at sparger rear, separator has some through flow holes.
