Description
Technical field
The invention belongs to the gas gathering and transportation manufacturing mechanism, particularly in the gas gathering and transportation production to containing a kind of buffering that a small amount of sand removes system of removing sand in the rock gas.
Background technique
In Su Lige gas field gas gathering and transportation is produced; Contain a small amount of sand in the rock gas; As do not remove sand, have following safety problem: 1. the flowmeter that uses in the well site receives washing away of sand for a long time, and measuring element is fragile; Cause the well head gas metering inaccurate, be unfavorable for analyzing on-the-spot running state; 2. because well site, Su Lige gas field is the digitizing well site, unmanned, the urgent block valve PRESSURE PIPE of high low pressure that the well site is provided with by the sand obstruction, when leakage or superpressure take place the gas production main, can not guarantee urgent block valve normal turn-off easily, stay potential safety hazard; 3. gas gathering station separator PRESSURE PIPE is stopped up by sand easily, can't detect the liquid level in the separator, stays potential safety hazard; 4. the drain valve of gas gathering station is stopped up by sand easily, can not carry out discharge opeing, influences ordinary production; 5. the 1.5D elbow of gas gathering station the inside is owing to receive washing away of sand for a long time, and thorn leaks easily; In order to guarantee the safety in production of gas gathering station field, well site, so carry out the remove sand development of device of well site.
At present, though the device that removes sand has passed through improvement many times, when not solving the cleaning sand and dust all the time; The defeated time-out problem that needs of natural gas tube; When both needing the cleaning sand and dust, must close former and later two valves of device that remove sand at every turn, release the pressure of the device section of removing sand then; Again filter core take out is cleaned and removes sand, during the defeated halted state that is in of natural gas tube.
Summary of the invention
The purpose of this invention is to provide a kind of neither influence and produce, a kind of buffering that can alleviate workload again system of removing sand.So that realize the defeated and defeated middle purpose of removing sand and dust of pipe of the continuous pipe of rock gas.
The objective of the invention is to realize like this, a kind of buffering system of removing sand is characterized in that: comprise a buffer; Buffer connects suction port and air outlet through pipeline, and vertical fixing has filter screen in the buffer, and suction port connects filter screen one end through pipeline; The filter screen the other end connects sand storage chamber through piping flange, and first ball valve is arranged on the piping flange, and sand storage chamber is through the sealing for tubing joints unit; Sand storage chamber one side has Decompression valves, and buffer is fixed on the support; During work; Containing a small amount of sand rock gas is connected with in the buffer of filter screen from the suction port entering; To contain a small amount of sand filter in the rock gas of a small amount of sand through filter screen in sand storage chamber; Then from the air outlet output of buffer one side, sand gets into the filter sand passage to rock gas, and rock gas gets into the rock gas passage.
Described filter screen is big with the port that suction port one end is connected, and filter screen is little with the port that piping flange one end is connected, and in buffer, buffer is communicated with the air outlet through outlet pipe filter screen integral body by vertical seal.
Described filter screen is big with the port that suction port one end is connected, and filter screen is little with the port that piping flange one end is connected, and in buffer, buffer is communicated with the air outlet through outlet pipe filter screen integral body by horizontal seal.
Described sealing unit is the sealing cover or second ball valve.
In the described sand storage chamber sensor is arranged, the sand storage chamber lower end connects second ball valve through pipeline, and sensor, Decompression valves, first ball valve, second ball valve and control unit are electrically connected; When sand got into the filter sand passage, the sand in sand storage chamber reached certain amount, and the sensor in the sand storage chamber passes the signal to control unit; Control unit is given the first ball valve out code; Treat first ball valve close put in place after, give Decompression valves open command, pressure release emptying by control unit; Treat Decompression valves open put in place after, give the second ball valve open command by control unit, by control unit regularly after 1 minute; Give the second ball valve out code; Treat second ball valve close put in place after, give the Decompression valves out code by control unit, treat Decompression valves close put in place after; Give the first ball valve open command by control unit, get into new work.
Advantage of the present invention: the present invention has used buffering, locellus to remove sand, the defeated time-out problem of pipe when not only having solved rock gas and removing sand, and avoided the cleaning of filter screen, and have and remove sand, do not influence production, alleviate the advantage of workload.Exempt the work that on-the-spot employee frequently clears up filter screen simultaneously, improved economic benefit.
