Detailed Description

Referring to fig. 2, it is illustrated that the bubble sifting propeller in a liquid tube according to the present invention can be easily implemented by a method of propelling bubbles in a liquid tube, the method of propelling bubbles in a liquid tube comprising the steps of S1 to S3 in sequence:

step S1: directing the gas into the inlet tube.

Referring to fig. 2a, a gas conduit 40 is connected to a liquid conduit 50, wherein the gas conduit 40 is used to conduct leaking gas from an industrial facility, such as a heat exchange facility, a boiler, a heat treatment facility, a gas facility, or a waste gas treatment facility, having process gases. As known in the art, in order to prevent the process gas from leaking, a gas conduit 40 for guiding the leaking gas is usually installed at a position where the process gas is likely to leak, such as a guiding pipe for guiding the process gas, a pipe connector of a gas storage chamber, a lid connector, etc., so as to prevent the process gas from leaking into the atmosphere. The liquid pipe 50 is filled with a liquid 20, and the liquid 20 may be water or other oil or solvent which does not affect the generation and floating of bubbles. In this manner, the gas conduit 40 is enabled to guide the leaking gas to generate bubbles 10 in the liquid 20 in the liquid tube 50.

Step S2: the bubble flow is driven.

Referring to fig. 2b, it is illustrated that a driving force is provided to the liquid 20 in the liquid tube 50 to drive the flow velocity of the liquid 20 and further drive the bubbles 10 in the liquid tube 50 to flow, so as to prevent the bubbles 10 from accumulating in the liquid tube 20 and generating an air lock, and the driving force is formed by a driving force provided by a driver.

Step S3: the bubble volume range is constrained.

Referring to fig. 2c, the liquid tube 50 is at least partially immersed in the liquid 20 in a liquid tank 70. the liquid tank 70 can be enclosed by a transparent or opaque tank wall frame, so that the liquid tank 70 is connected to the atmosphere and filled with the liquid 20, and the density of the liquid 20 in the liquid tank 70 is the same as that of the liquid 20 in the liquid tube 50. The liquid pipe 50 sinking into the liquid 20 in the liquid tank 70 is connected to a bubble trap 80 also sinking into the liquid 20 in the liquid tank 70, the bubble trap 80 being used to confine the bubble volume range of the bubbles 10. More specifically, the bubble sifter 80 sifts the bubble volume in the liquid pipe 50 in the liquid 20 of the liquid tank 70, decomposes an excessive bubble 11 larger than the bubble volume range into an excessive bubble 12 and a monitoring bubble 13, and changes the bubble 10 smaller than the bubble volume range into the monitoring bubble 13, and the excessive bubble 12 is drained into the liquid 20 of the liquid tank 70 and separated from the liquid pipe 50 by the driving force, and the monitoring bubble 13 is guided by the liquid pipe 50 to be detected.

On the other hand, referring to fig. 3 and 4, the present invention provides a bubble sifting impeller in a liquid tube, which includes a body 30 and a pressure tube 60. Wherein:

a liquid pipe flow passage 31 is formed inside the device body 30, both ends of the liquid pipe flow passage 31 respectively extend to the surface of the device body 30 to form a liquid supply pipe joint 34 and a liquid discharge pipe joint 35 which are parallel to each other, the liquid supply pipe joint 34 is used for connecting a liquid supply pipe 51 for supplying bubbles 10, the liquid discharge pipe joint 35 is used for connecting a liquid discharge pipe 52 for detecting discharged bubbles 10, the liquid supply pipe joint 34 is made into a semicircular pipe wall shape in implementation, and the liquid discharge pipe joint 35 is made into a pipe hole shape in implementation. Further, the liquid supply pipe adapter port 34 and the liquid discharge pipe adapter port 35 have different height differences, and in practice, the liquid supply pipe adapter port 34 is located at a height relatively lower than the liquid discharge pipe adapter port 35 in the bubble accommodating chamber 32.

The container 30 has a bubble chamber 32 formed therein, the liquid pipe passage 31 extends through the bubble chamber 32, the liquid supply pipe connection port 34 and the liquid discharge pipe connection port 35 are communicated with each other via the bubble chamber 32, and the liquid supply pipe 51 is communicated with the liquid discharge pipe 52 via the bubble chamber 32. The device body 30 is further provided with an open notch 33 connected with the bubble accommodating chamber 32 on the end wall of the same side with the liquid feeding pipe joint 34, the open notch 33 is higher than the liquid feeding pipe joint 34, and the opening area of the liquid feeding pipe joint 34 is smaller than the open notch 33, so that the bubbles 10 can rapidly leave the bubble accommodating chamber 32 through the open notch 33 after entering the bubble accommodating chamber 32 from the liquid feeding pipe 51, and cannot be accumulated in the bubble accommodating chamber 32 to form an air lock phenomenon. In addition, one end of the liquid supply tube 51 is embedded in the bubble accommodating chamber 32, so that the bubbles 10 enter the bubble accommodating chamber 32 and then approach the liquid discharge tube 52, thereby facilitating the entry of part of the bubbles 10 (i.e. the monitoring bubbles 13) into the liquid discharge tube 52.

The pressure pipe 60 is connected to the drain pipe 52 at one end and connected to a driver (not shown) for driving the liquid 20 in the pressure pipe 60 to flow into the drain pipe 52, which may be a liquid pump. Further, the pressure pipe 60 is connected to the drain pipe 52 through a tee element 90, the tee element 90 has a first inlet 91, a second inlet 92 and an outlet 93, the first inlet 91 is connected to the drain pipe 52, the second inlet 92 is connected to the pressure pipe 60, the outlet 93 is used for draining the liquid 20, an included angle between the first inlet 91 and the second inlet 92 is greater than 0 degree and less than 180 degrees, and an included angle between the first inlet 91 and the second inlet 92 and the outlet 93 is greater than 90 degrees and less than 180 degrees, so that when the liquid 20 in the pressure pipe 60 flows into the drain pipe 52, the liquid 20 in the drain pipe 52 can be smoothly driven to flow to the outlet 93. The pressure pipe 60 may be formed by extending from the drain pipe 52 side.

Referring to fig. 5a to 5c, the operation of the present invention will be described in order to connect the gas conduit 40 for guiding the leaking gas to the liquid supply pipe 51, so that the gas in the gas conduit 40 generates the bubbles 10 in the liquid 20 in the liquid supply pipe 51, and at the same time, the liquid 20 in the pressure pipe 60 flows into the liquid discharge pipe 52 by the driving of the driver, and further drives the liquid 20 in the liquid discharge pipe 52 to flow, so that the liquid 20 in the liquid supply pipe 51 flows along, and the bubbles 10 in the liquid supply pipe 51 flow from the liquid supply pipe 51 to the bubble accommodating chamber 32 (as shown in fig. 5 a) by the driving of the liquid 20, wherein the bubbles 11 include the excessive bubbles 11 accumulated in the liquid supply pipe 51, and the excessive bubbles 11 have a volume larger than the preset bubble volume range.

When the excessive bubbles 11 enter the bubble accommodating chamber 32 through the liquid feeding pipe 51 (as shown in fig. 5 b), the excessive bubbles 11 float upward, and during the floating, the excessive bubbles 11 are decomposed into the excessive bubbles 12 and the monitoring bubbles 13, the bubble volume of the excessive bubbles 12 is larger than that of the monitoring bubbles 13, and the excessive bubbles 12 are discharged out of the bubble accommodating chamber 32 through the opening notch 33 and enter the liquid tank 70 due to the buoyancy thereof.

Since the bubble volume of the monitoring bubbles 13 is smaller than that of the excess bubbles 12, that is, the buoyancy of the monitoring bubbles 13 is smaller than that of the excess bubbles 12, when the liquid 20 in the drain pipe 52 is driven by the pressurization pipe 60 to flow, a negative pressure state is formed in the drain pipe 52, so that the monitoring bubbles 13 with smaller buoyancy are sucked into the drain pipe 52 (as shown in fig. 5 c), and thus, the bubble volume is screened for facilitating the subsequent detection operation.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
