Description

A kind of anti-pollution natural gas flowmeter
Technical field
The utility model is related to gas flow measurement technical fields, are specially a kind of anti-pollution natural gas flowmeter.
Background technology
The operation principle of soap film flowmeter:Generate soap-film in soap-film pipe, measured gas through soap-film pipe lower end into Gas port enters soap-film pipe, and soap-film is promoted at the uniform velocity to rise along soap-film pipe, when soap-film rises to the lower graduation mark of soap-film pipe, timing Device starts timing, and when soap-film rises to soap-film pipe high scale line, timer stops timing, by the time measured and soap-film pipe two Volume between graduation mark can calculate the flow for flowing through soap film flowmeter.
At present, well known natural gas flowmeter is mostly all by housing (Venturi tube), swirl generating body, baffle, frequency The components such as sensing member (piezo-electric crystal), microprocessor, temperature and pressure sensor form.Using Karman vortex street principle, stream is utilized The linear relation of flow velocity of cross frequence and fluid that body generates whirlpool calculates outflow.But there is usual slag inclusion in natural gas Heavy component oil, the flowmeter of the prior art can cling flowmeter float by heavy component oily pollution, difficulty caused to measurement, hold Easily cause the judgement of mistake or even damage flowmeter.
Utility model content
For in the prior art the defects of, the utility model provides a kind of anti-pollution natural gas flowmeter, can dissolve The heavy component oil being mingled in natural gas, prevents flowmeter to be contaminated, can conveniently measure gas discharge, measurement error It is small.
Technical solutions of the utility model are as follows:
A kind of anti-pollution natural gas flowmeter, key are:Including air inlet, gas outlet, the spherical appearance equipped with solvent Device, bubble emit pipe, solvent adding set, waste liquid recovery apparatus;Equipped with being capable of heavy component in dissolved natural gas in the spherical container Oil and it can generate and steep the solvent that emits;Bubble has been connected up at the top of the spherical container and has emitted pipe, it is described to steep the top and the bottom for emitting pipe surface High scale line and lower graduation mark are respectively arranged with, bubble emits tube top portion equipped with gas outlet;Left side and air inlet in the middle part of the spherical container It is connected, is connected on the right side of middle part by the first ball valve with solvent adding set, bottom is filled by the second ball valve and devil liquor recovery It puts and is connected;The solvent adding set is higher than spherical container.
During flow meters work, natural gas flow velocity is controlled, natural gas to be measured is made at the uniform velocity to enter the flowmeter from air inlet.Then The first ball valve is opened, solvent adding set adds solvent into spherical container, until the solvent liquid level in spherical container is higher than appearance At the top of device, the first ball valve is closed.Heavy component oil in natural gas then dissolves purification by the solvent in spherical container.And spherical shape is held Solvent in device is passed into due to being passed through natural gas, gas in solvent, bubble emit bottom of the tube can generate bubble emit (be similar to soap Film).Under the effect of the pressure, natural gas promotes the bubble to emit and emits pipe along bubble and at the uniform velocity rise, and when bubble, which emits, rises to lower graduation mark, opens Beginning timing, when bubble, which emits, rises to high scale line, timer stops timing, is emitted by the time measured and bubble between two graduation mark of pipe 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.
