Please refer to Fig. 2, which illustrates that the bubble screening pusher in the liquid tube provided by the present invention can be easily implemented through a bubble push method in the liquid tube. The bubble push method in the liquid tube includes the following steps S1 to S3 steps:

Step S1: Lead the gas into the liquid pipe.

Please refer to Figure 2a to illustrate connecting a gas conduit 40 to a liquid pipe 50. The gas conduit 40 is used to guide the leaking gas of industrial equipment. The industrial equipment can be heat exchange equipment with process gas, boilers, heat treatment equipment, Gas equipment or waste gas treatment equipment, etc. According to common knowledge, in order to prevent the leakage of process gas, these industrial equipment usually install diversion leaking gas in the diversion pipeline that diverts the process gas or the pipeline interface of the gas storage tank, the hatch cover interface, etc. The gas conduit 40 prevents the process gas from leaking into the atmosphere. The liquid tube 50 is filled with a liquid 20, and the liquid 20 may be water or other oil or solvent that does not affect the formation and floating of bubbles. In this way, the gas conduit 40 can guide the leaking gas to generate bubbles 10 in the liquid 20 of the liquid pipe 50.

Step S2: Drive the air bubbles to flow.

Please refer to Figure 2b, which illustrates that a driving force is provided to the liquid 20 in the liquid tube 50 to drive the flow rate of the liquid 20, thereby driving the bubbles 10 in the liquid tube 50 to flow, and avoiding the accumulation of the bubbles 10 in the liquid tube 20 to generate a gas lock Phenomenon, the driving force is formed by the thrust provided by a driver in practice.

Step S3: restrict the bubble volume range.

2c, it is illustrated that at least a part of the liquid pipe 50 is sunk into the liquid 20 of a liquid tank 70. The liquid tank 70 may be framed by a transparent or opaque tank wall, so that the liquid tank 70 is connected to the atmosphere and filled with liquid 20. The density of the liquid 20 in the liquid tank 70 is the same as that of the liquid 20 in the liquid pipe 50. The liquid pipe 50 that sinks into the liquid 20 of the liquid tank 70 is connected to a bubble filter 80 that also sinks into the liquid 20 of the liquid tank 70, and the bubble filter 80 is used to restrict the bubble volume range of the bubble 10. More specifically, the bubble filter 80 screens the bubble volume in the liquid tube 50 in the liquid 20 of the liquid tank 70, so that the excessively large bubble 11 that is larger than the bubble volume range is decomposed into an excess bubble 12 and a monitoring bubble 13. And let the bubble 10 smaller than the bubble volume range become the monitoring bubble 13, and driven by the driving force, the excess bubbles 12 are drained into the liquid 20 in the liquid tank 70 and leave the liquid pipe 50, and the monitoring bubble 13 passes through The liquid pipe 50 is guided and detected.

On the other hand, please refer to FIGS. 3 and 4 together to illustrate a bubble screening propeller in a liquid tube provided by the present invention, which includes a body 30 and a pressurizing tube 60. among them:

The liquid supply pipe connection port 34 is used to connect a liquid supply pipe 51 that provides bubbles 10, and the discharge pipe connection port 35 is used to connect a liquid discharge pipe 52 that discharges bubbles 10 for detection. The liquid supply pipe connection port 34 In the implementation, it is made into a semicircular tube wall shape, and the discharge pipe adapter 35 is made into a tube hole shape in the implementation. Furthermore, there are different height differences between the liquid supply pipe connection port 34 and the discharge pipe connection port 35. In specific implementation, the height of the liquid supply pipe connection port 34 in the bubble containing chamber 32 is relatively low. At the drain pipe connection interface 35.

A bubble accommodating chamber 32 is formed in the body 30, the liquid pipe channel 31 extends through the bubble accommodating chamber 32, and the liquid supply pipe connection port 34 and the liquid discharge pipe connection port 35 are mutually connected via the bubble accommodating chamber 32. The liquid supply pipe 51 communicates with the liquid discharge pipe 52 through the bubble containing chamber 32. The body 30 also forms an open slot 33 communicating with the bubble containing chamber 32 on the same side end wall where the liquid supply pipe adapter 34 is formed, and the height of the open groove 33 is relatively higher than the liquid supply pipe adapter 34, and the opening area of the liquid supply pipe connecting port 34 is smaller than the open slot 33, so that after the bubble 10 enters the bubble containing chamber 32 from the liquid supply tube 51, it can quickly leave the bubble containing chamber 32 through the open slot 33. It will accumulate in the bubble containing chamber 32 to form an air lock phenomenon. In addition, one end of the liquid supply tube 51 is implanted in the bubble containing chamber 32, so that the bubble 10 enters the bubble containing chamber 32 and then approaches the drain tube 52, so that part of the bubble 10 (that is, the monitoring bubble 13) enters the drain tube. 52 in.

One end of the pressurizing pipe 60 is connected to the drain pipe 52, and the other end is connected with a driver (not shown). The driver is used to drive the liquid 20 in the pressurizing pipe 60 to flow into the drain pipe 52. The driver can be implemented as Liquid pump. Furthermore, the pressure pipe 60 and the discharge pipe 52 are connected through a three-way element 90 in practice, and the three-way element 90 has a first inlet 91, a second inlet 92 and an outlet that are connected. 93, its The first inlet 91 is used to connect to the drain pipe 52, the second inlet 92 is used to connect to the pressurizing pipe 60, the outlet 93 is used to drain the liquid 20, and the gap between the first inlet 91 and the second inlet 92 The included angle is greater than 0 degrees and less than 180 degrees. The included angles between the first inlet 91 and the second inlet 92 and the outlet 93 are greater than 90 degrees and less than or equal to 180 degrees. When the liquid 20 in the pressurizing pipe 60 flows into the drain When in the tube 52, the liquid 20 in the drain tube 52 can be smoothly driven to flow to the outlet 93. In addition, the pressurizing tube 60 may be formed by extending from one side of the drain tube 52 in practice.

According to the above configuration, please refer to Figs. 5a to 5c successively to disclose the action explanatory diagrams of the present invention. The gas pipe 40 for guiding the leaking gas is connected to the liquid supply pipe 51 so that the gas in the gas pipe 40 is in the liquid supply. Bubbles 10 are generated in the liquid 20 of the tube 51. At the same time, the liquid 20 in the pressurizing tube 60 flows into the drain tube 52 through the drive of the driver, and then drives the liquid 20 in the drain tube 52 to flow, making the liquid supply tube 51 The liquid 20 inside follows the flow, so that the bubbles 10 in the liquid feeding pipe 51 are driven by the liquid 20 to flow from the liquid feeding pipe 51 to the bubble containing chamber 32 (as shown in FIG. 5a), which contains the accumulation in the liquid feeding pipe 51 The oversized bubble 11 is formed, and the oversized bubble 11 means that its volume is larger than the preset bubble volume range.

When the excessively large bubble 11 enters the bubble containing chamber 32 through the liquid supply pipe 51 (as shown in FIG. 5b), the excessively large bubble 11 will float up, and during the upward process, the excessively large bubble 11 will decompose into excess bubbles 12 and monitor The bubble 13, the bubble volume of the excess bubble 12 is larger than the monitoring bubble 13, the excess bubble 12 will drain out of the bubble containing chamber 32 through the open slot 33 due to its buoyancy and enter the liquid tank 70.

Since the bubble volume of the monitoring bubble 13 is smaller than that of the excess bubble 12, that is, the buoyancy of the monitoring bubble 13 is less than that of the excess bubble 12. When the liquid 20 in the discharge pipe 52 is driven by the pressure pipe 60 to flow, the discharge pipe A negative pressure state is formed in 52, so that the monitoring bubbles 13 with relatively small buoyancy will be sucked into the discharge pipe 52 (as shown in FIG. 5c), so as to filter the bubble volume for subsequent detection operations.

The above embodiments only express the preferred embodiments of the present invention, but they should not be interpreted as limiting the scope of the present invention. Therefore, this new model should be subject to the content of the claims defined in the scope of the patent application.
