Volume can calculate the flow for flowing through the flowmeter.After metering, the second ball valve is opened so that dissolved in spherical container
The waste oil of heavy component enters waste liquid recovery apparatus and is recycled.
The utility model is packed into the solvent that can dissolve heavy component oil, dissolving by setting spherical container in spherical container
It is measured again after having purified the heavy component oil in natural gas.It effectively prevents heavy component oily pollution flowmeter and causes measurement not
Accurately in addition damage flowmeter.Flowmeter will not be polluted compared to traditional natural gas flowmeter the utility model, so as to measure knot
Fruit is more accurate.
Further, emitted in the bubble and diameter is additionally provided at the top of pipe emits the big bubble of pipe than bubble and emit storage area, which emits
It is connected at the top of storage area with gas outlet, side emits retracting device with bubble by shut-off valve and is connected.Bubble emits storage area and bubble emits
Retracting device emits for recycling bubble.
Further, the air inlet is U-shaped air inlet, and the inlet end of the U-shaped air inlet is higher than outlet side.Prevent ball
Describe the solvent suck-back in device.
Further, the solvent is UDS solvents.The heavy component oil solute effect being mingled with to natural gas is good, and raw material
It is cheap and easy to get, reduce cost.
Further, the gas outlet is equipped with filter membrane.
