な流量測定を行うことが困難であつた。
When measuring the flow rate in a vacuum car for treating human waste, the following method has been used in the past, making it difficult to accurately measure the flow rate.
(1) 吸込効果を上げるため、間欠的に空気を送り
込む操作を行なう必要があること。(1) In order to increase the suction effect, it is necessary to perform an operation to pump air intermittently.
(2) 吸込んだ液体がタンクに近づくにつれて真空

なつて出てくる。(2) As the sucked liquid approaches the tank, the degree of vacuum increases, and the gas dissolved in the liquid comes out as bubbles.
汲取量の測定のためにタンクにガラスゲージが
設置してあるが、車体の姿勢により誤差が大き

The present invention was developed in view of these points, and is a gas-liquid separation system that enables accurate flow measurement by providing a separation tank in the front stage of a flowmeter to separate the gas contained in the liquid. This is the realization of the device.
以下、図面を参照して本考案を詳細に説明す

Hereinafter, the present invention will be described in detail with reference to the drawings.

中に取付けられたバルブである。 FIG. 1 is a mechanical configuration diagram showing an embodiment of the present invention. In the figure, 1 is an inlet pipe into which human waste etc. flows, 2 is a tank (gas-liquid separation tank) that takes in a liquid containing gas and separates the gas and liquid, 3
1 is an internal pipe in which an inlet pipe 1 penetrates into the tank 2, and its shape is such that its tip rises upward. 4 is tank 2
A first pipe 5 is installed at the bottom of the tank 2 to discharge the liquid accumulated at the bottom of the tank 2, and a first pipe 5 is installed at the top of the tank 2 to bypass the separated gas. 2 is a pipe (gas bypass pipe), 6 is an outlet pipe in which the first pipe and the second pipe are combined at the outlet, 7 is a flow meter installed in the middle of the first pipe 4, and V is a first pipe. This valve is installed in the middle of the pipe 5 of No. 2.
し尿等の流体は固形分を含むために、その流量
測定のための流量計としては管内に突起物を有し
ない電磁流量計が測定精度も高く最適である。 Since fluids such as human waste contain solid content, an electromagnetic flowmeter having no protrusions inside the tube is most suitable for measuring the flow rate because of its high measurement accuracy.

須の要件である。 Human waste flowing from the suction port enters the tank 2, where gas and liquid are separated. tank 2
The fluid that has entered the tank is spouted into the tank because the tip of the internal pipe 3 stands up inside the tank, and gas bubbles mixed in the liquid are separated. The separated liquid is transferred to a first pipe 4,
It enters a vacuum tank (not shown) through outlet piping 6. During this time, the flow rate of human waste, etc. is measured by the flow meter 7 attached to the first pipe 4. On the other hand, the separated gas flows through the second pipe 5 to the outlet. In this way, under normal operating conditions, only liquid flows through the flow meter 7 as described above, making it possible to measure the flow rate. The liquid flowing through the flowmeter does not contain gas due to the gas-liquid separation operation described above, which allows accurate flow rate measurement. When an electromagnetic flowmeter is used as a flowmeter, a structure in which no gas is contained in the flowmeter is an essential requirement for maintaining measurement accuracy.

し、正確に流量０を実現することができる。 According to the present invention, in order to prevent gas from flowing to the flow meter 7 even when almost only air flows at the end of pumping, the outlet level is set to the first level.
By installing the pipe H above the pipe 4, when the flow rate of the liquid becomes 0 and only air is flowing, the pressure drop ΔP of the air due to the pipe 5, the specific gravity ρ of the liquid, H, and the liquid level can be calculated. When the head pressure ρh due to the difference h is balanced and ΔP=ρh, the flow meter 7 is filled with liquid, and a flow rate of 0 can be accurately achieved.

いる。 FIG. 2 is a diagram showing an example in which the present invention is applied to a vacuum car. Components that are the same as those in FIG. 1 are designated with the same numbers. In the figure, 10 is a gas-liquid separation device according to the present invention. 11 is a vacuum tank, 12 is a suction port, 13 is a hose reel for winding up the hose 14, 15 is a suction port, and 16 is an exhaust port. The device of the present invention is an embodiment installed in a vacuum car for collecting human waste. Normally, the distance from the suction port 15 to the pumping port 12 is 50m wound around the hose reel 13.
Since the entire area from the hose wound on a reel to the intake port 12 is a movable part, a flow rate measuring device cannot be attached. Therefore, a flow measuring device consisting of a gas-liquid separator 10 and a flow meter 7 is installed at the reel outlet and the suction port 1 to the tank 11.
It was installed between 5 and 5. Internal air is exhausted from the vacuum tank 11 through an exhaust port 16 connected to a vacuum pump (not shown), creating a vacuum of about 600 mmHg at maximum. As described above, the gas-liquid separator 10 functions to measure the amount of pumped gas by flowing the gas through the gas bypass pipe 5 and the flow rate through the flow meter 7.

As explained in detail above, according to the present invention,
A gas-liquid separation tank can be provided to separate gas from liquid to enable accurate flow measurements.
