Abstract

PURPOSE:To constitute a strainer having a gas-liquid separating function, to which another function to discharge an excess of gas to the outside of a device by detecting the lowering of liquid level resulting from an increase of a separated gas phase is added. CONSTITUTION:When COM flows into the outside of a cylindrical filtering body 17 from a flow-in port 5 of a treating tank 4, coarse particles are captured by a filtering surface, and the COM containing a portion of small particles smaller than the regulated screen openings of the filtering surface passes through the surface to flow out of a discharging port 6. A gas phase portion contained in the COM is captured on the filtering surface to grow up to gas bubbles, and the gas bubbles are gathered by a scraper 18 sliding on the filtering surface and rise along the scraper 18 to be stored in a separated gas storing part 9 through holes of a buffle plate 8, and the liquid level is lowered with an increase of the stored gas, and accordingly, a float 11 is lowered which causes an opening of a gas exhausting port 10 to discharge the gas portion, and also that causes the rise of liquid level to close the port 10 by a valve 14. The coarse particles are discharged from a drain port 7 by a scraper 16.

The present invention relates to a strainer with a gas-liquid separation function, which is equipped with a strainer that removes powder and a gas-liquid separation device that automatically separates and removes the gas phase.

Ｍの取引の為の正確な量目計量は絶対的な課題である。M has a very high viscosity. Since the mixed gas phase is difficult to remove, it is used without separating the gas and liquid. Furthermore, although coal powder is mainly pulverized and sieved using a ball mill or the like, excessive powder is removed because the mesh is relatively small. Since it is a fluid with OOMB multiphase components, handling it is extremely difficult, and we are currently at the stage of trying to apply a special flowmeter for the necessary measurements. Improvement of these factors (30
Accurate weighing for M transactions is an absolute challenge.

れることはトされないので取除く必要がある。Since volumetric flowmeters are currently optimal for high-precision measurement of high-viscosity fluids, the application of volumetric flowmeters can also be considered for measurement of COM. CO may get stuck in the child and cause it to stop rotating.
Since there are cases where the current does not behave like a pingham flow rate, various countermeasures have been taken for the applied volumetric flowmeters that are still used in OOMK. However, even with a positive displacement flowmeter that takes countermeasures, it is impossible to contain particles larger than a certain allowable size, so they must be removed.

It is necessary to use a "strainer" with a filtration function or a gas-liquid separator/equipment with a gas phase separation function as a container.Usually, as shown in Figure 1, a gas-liquid separator 2 is used to separate the gas phase. After removal, in order to prevent coarse particles from being mixed in with the strainer 3, a method of is#ing the piping 1 may be considered. Conventionally, there have been commercially available filters with a zero stem clean equipped with a scraper to remove coarse particles for the purpose of protecting transport pumps, etc., but there are gas-liquid separation filters with the purpose of improving flow rate measurement accuracy. No functions were added.

のである。This invention focuses on the fact that when COM having the above-mentioned characteristics collides with the mesh of a strainer, this kinetic energy is absorbed to combine and float a minute gas phase, and the liquid level caused by the separation of this gas phase is reduced. This strainer has a gas-liquid separation function by adding a function of detecting a change in the liquid level, that is, a drop in the liquid level caused by an increase in the separated gas phase, and discharging it outside the vessel.

When Cl0M collides with the filtration surface, the gas phase contained in 00M is captured on the filtration surface and becomes bubbles, and when the Cl0M is slid on the filtration surface by the scraper 8, the bubbles are focused and moved along the scraper 8. The separated gas reservoir q floats up and passes through the hole in the baffle plate 8.
As the liquid is stored in the tank, the liquid level decreases and the 70-t 11 goes down. Along with this, the valve 14 also goes down, the exhaust port 10 opens, and the gas phase is discharged, and the liquid level rises again. valve 14
closes the exhaust port 10.

You can safely reach your goal without having to do anything.

。Here, as a filtration method, the filtration cylinder 17 is fixed and the scraper 16 is rotated.
The same effect can be obtained by fixing the filtration cylinder 17 and rotating the filtration cylinder 17. In short, the same effect can be obtained by applying a relative rotational movement between the filtration cylinder 17 and the scraper 16 to cause them to slide.

したためである。In addition, a porous baffle plate was used to stabilize the liquid level and send the air upstream through the tank, but since this uses a float-type liquid level detection method, local fluctuations in water level may occur. This is for the purpose of preventing vibrational opening and closing of the valve due to K.

おけばバッフルプレート８を必要とし々い。Therefore, the liquid level detection method is to use a capacitive liquid level meter that uses capacitance that changes in proportion to the change in liquid level, or an ultrasonic wave that uses the fact that ultrasonic propagation time is proportional to the change in liquid level. The valve may be opened or closed by detecting it with a liquid level gauge or other method. In this case, the baffle plate 8 is often required if the operating range φ for opening and closing the valve at a predetermined liquid level is defined.

リットは大であ小０As mentioned above, by sliding relative rotation concentrically with the filtering surface of the cylindrical strainer, the gas-liquid separation is not only long enough to remove coarse particles, but also for the purpose of improving the measurement space of the flowmeter. Because it has a function, there is no need to install separate devices with separate functions to supplement the flowmeter, and by functioning as a single unit, the economic benefits such as y * area and price are large or small.
