Description
Technical field
The invention belongs to liquid level sensor technical fields, and in particular to be a kind of photosensitive liquidometer and its application method,
For the tank reactor with stirring, when reaction mass is pumped into discharge, to reaction kettle material liquid surface real-time measurement and control
In zone of reasonableness.
Background technique
Tank reactor is widely used in chemistry, chemical industry.And the tank reactor of continuous slurry bed system, reactant
The inlet and outlet of material carries out simultaneously, and material is in muddy in Fu.In order to control the liquid level in reaction kettle certain normal
In range, it would be desirable to which real-time measurement liquid level is simultaneously controlled by multiple means.Process condition (muddy object needed for reaction
Material, 0 ~ 5 atmospheric pressure pressure, 50 ~ 120 degrees Celsius and center impeller stirring) measure traditional liquid level meter can not accurately.
The common liquid level of existing market is in respect of ultrasonic wave (radar) liquidometer, laser liquid level gauge, float-ball type magnetic turning plate liquid level
Meter, side-mounted liquidometer etc..
Ultrasonic level gage is mainly sent with the time of reflection by detection ultrasonic wave and calculates liquid level, thus be easy by
The energy loss propagated to ultrasonic wave influences, and is not suitable for using in the environment for inhaling wave rugged environment such as mud, powder.
Laser liquid level gauge measures liquid level by the irradiation and reflection of laser, but is mounted in huge reaction kettle
Relatively far apart, weak output signal, intensive reading is difficult to reach for laser emitter and receiver on wall.
And the side-mounted liquidometer of glass tube easily causes the accumulation of mud Solid content and leads due to being mounted on container side, nozzle
Cause blocking.
Float-ball type magnetic double level gauge indicates liquid level by the up and down motion and magnet of the floating ball on liquid level, the liquidometer
Working effect is good in standby fluid level, and the liquidometer more used currently on the market.But it is moved when the liquidometer is used in
State environment (in the reaction kettle containing agitator arm), liquid flowing bring frictional force can make the up and down motion of floating ball not smart enough
Really, such as biggish stiction can make floating ball be difficult to setting in motion to capture and lead to intensive reading drop less than subtle fluid change
It is low.In addition, even if in floating ball exterior measuring plus anti-wave tube to reduce the influence that liquid fluctuating moves up and down for floating ball, magnetic turning plate liquid
The intensive reading of position meter measurement is still limited by overturning magnet diameter.
Tuning fork liquidometer is similar with ultrasonic wave, liquid level is measured by the transmitting and reception of sound wave, when sound wave is by material
When resistance exercise, amplitude is drastically reduced and significant change occurs for frequency and phase, to be detected by internal electronics.It
Operation is really from the shadow of flowing, turbulent flow, bubble, foam, vibration, solid content, coating, characteristics of liquids and product variations
It rings, and tuning fork liquidometer is more often used frequently as liquid-level switch, when liquid level has been submerged in tuning fork bottom end, damping vibration is with liquid level
Variation it is smaller, accurate data can not be provided for specific liquid level.
