The level gauging of opening reactive tank just becomes more difficult, and more serious influence is caused to normal Chemical Manufacture.Make now
Measurement scheme accesses pressure point extraction pressure guiding pipe using reaction tank bottom opening and is directly accessed the measurement of diaphragm pressure transmitter, but
Because slurry used in Chemical Manufacture is more special, stickiness is high, solid content is high, easily blocks impulse pipeline, and liquid level is normal
Time of measuring is relatively short, it is impossible to permanently effective to instruct technique productions.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of blowing type liquid level measurement apparatus.
The utility model is achieved by the following technical programs.
A kind of blowing type liquid level measurement apparatus provided by the utility model, including reaction vessel, measurement control valve, liquid level are drawn
Pressure pipe, pressure transmitter, flowmeter, flow control valve, cleaning control valve and cleaning scavenging conduit, reaction vessel are provided with liquid level and taken
Mouth is pressed, liquid level pressure guiding pipe and cleaning scavenging conduit are accessed in liquid level pressure tappings；On liquid level pressure guiding pipe with air current flow direction successively
Flow control valve, flowmeter, pressure transmitter and measurement control valve are set；Cleaning control valve is arranged on cleaning scavenging conduit.
The liquid level pressure tappings are DN80 mouths.
The pressure transmitter is specially BST6800-GP pressure transmitters.
The flow is calculated as metallic rotameter.
The inlet end of cleaning scavenging conduit is connected with liquid level pressure guiding pipe, and junction is located at the front end of flow control valve.
Hand control valve is provided with before pressure transmitter.
The cleaning scavenging conduit uses DN25 mouths access liquid level pressure tappings.
Liquid level pressure tappings are inclined upwardly, and are in 45 degree of angles with the side wall of reaction vessel.
The beneficial effects of the utility model are：The utility model adds cleaning on the basis of traditional liquid level meter
Blow device, cleaning work periodically can be carried out to liquid level pressure tappings, prevent the blocking of the impulse pipeline caused by the crystallization of slurry,
Ensure the accuracy of level gauging during Chemical Manufacture.

Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As illustrated, a kind of blowing type liquid level measurement apparatus, including reaction vessel 1, measurement control valve 3, liquid level pressure guiding pipe
4th, pressure transmitter 5, flowmeter 6, flow control valve 7, cleaning control valve 8 and cleaning scavenging conduit 9, reaction vessel 1 are provided with liquid
Position pressure tappings 2, set gradually flow control valve 7, flowmeter 6, pressure transmitter 5 on liquid level pressure guiding pipe 4 with air current flow direction
And measurement control valve 3；Cleaning control valve 8 is arranged on cleaning scavenging conduit 9.
Liquid level pressure tappings 2 are arranged at the side wall of reaction vessel 1, and specific height can be configured according to demand.
According to demand, the liquid level pressure tappings 2 could be arranged to DN80 mouths.
The pressure transmitter 5 is specially BST6800-GP pressure transmitters.
The flowmeter 6 is metallic rotameter.
The inlet end of cleaning scavenging conduit 9 is connected with liquid level pressure guiding pipe 4, before flow control valve 7.
Hand control valve 10 is provided with before pressure transmitter 5, when needing that pressure transmitter 5 is safeguarded or changed
Hand control valve 10 is closed, carries out the replacing and maintenance work of pressure transmitter 5.
Liquid level pressure tappings 2 are inclined upwardly, and the side wall with reaction vessel 1 is in 45 degree of angles, impulse mouth ring flange interface mode,
On flange liquid level pressure guiding pipe 4 is used as by the use of Φ 14- Φ 20 stainless steel tube.
During work, the steam less than or equal to 2.45MPa is introduced in liquid level pressure guiding pipe 4 and cleaning scavenging conduit 9, is carried out anti-
Answer the measurement of liquid level in container and the purging of the cleaning at liquid level pressure tappings 2；Installed before low-pressure steam enters measurement control valve 3
Metallic rotameter, to ensure that the steam flow flowed through stablizes constant, the installation flow control valve 7 before metallic rotameter
Steam flow is adjusted, the pressure change of the rear end of flowmeter 6 is measured with pressure transmitter 5, is pressed in the case where steam flow is stable
The change of liquid level is just directly reacted in the change of power transmitter 5.Now, cleaning control valve 8 remains turned-off.Cleaning scavenging conduit 9 accesses
Accessed at liquid level pressure tappings 2 using DN25 mouths, it is necessary to when being cleaned, open and clean control valve 8, cleared up in scavenging conduit 9
Steam be passed through in liquid level pressure tappings 2 and carry out purging cleaning, in scale removal process is purged, the flow for being passed through steam can also be increased
To obtain more preferable cleaning effect, now, flow control valve 7 is closed.
