Bubble screener in liquid pipe

Technical Field

The utility model discloses be applied to leakage gas and listen the field, relate to and prevent that leakage gas from producing the gas lock phenomenon in liquid pipe, and then provide a bubble screening washer in liquid pipe.

Background

Generally, industrial plants, such as heat exchangers, boilers, thermal processes, gas or exhaust gas processes, have process gases which are at most a specific pressure and are guided or stored by means of structural elements, such as pipes or chambers.

It is known that industrial equipment with process gas is prone to leakage of process gas after a period of time, which affects the adequacy of the industrial equipment. If the leaked process gas is toxic, it poses a threat to the environment, the health of personnel and even safety. Therefore, the process gases in these industrial facilities must be detected immediately upon leakage to maintain the equipment adequacy, sanitation and public safety.

As is known, in the existing industrial equipment for processing gas, a gas pressure sensor, a gas flow meter, etc. are mostly installed in a gas guiding pipe or a gas storage chamber, etc. to detect whether the processing gas leaks. However, it is difficult to accurately detect the gas leakage at a small flow rate in these prior art techniques.

The applicant has proposed a technique for detecting and detecting the leakage gas by introducing the leakage gas into the liquid pipe to generate bubbles and detecting the amount or volume of the bubbles generated in the liquid; however, when the flow rate of the leaking gas is too small, the thrust of the small flow rate of the leaking gas in the liquid tube is relatively reduced, so that the bubbles generated by the small flow rate of the leaking gas are easy to accumulate in the liquid tube to form too large bubbles with larger bubble volume, which affects the accuracy of the detection of the small flow rate of the leaking gas, and thus, improvement is needed.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is to improve the accuracy of the detection when the small flow gas leaks.

To achieve the above objects, a preferred embodiment of the present invention provides a bubble separator in a liquid tube to improve the accuracy of detection when a small flow of gas leaks. The technical means is that the device is provided with: a liquid pipe flow passage, the two ends of which are respectively connected with a liquid supply pipe for providing bubbles and a liquid discharge pipe for discharging bubbles for detection; the liquid pipe flow passage penetrates through the bubble accommodating chamber, and the liquid supply pipe is communicated with the liquid discharge pipe through the bubble accommodating chamber; (ii) a The bubble containing chamber and the open notch jointly screen the bubble volume range of the bubbles provided by the liquid supply pipe, so that an overlarge bubble which is larger than the bubble volume range is decomposed into an excess bubble and a monitoring bubble, the excess bubble flows out of the bubble containing chamber through the open notch, and the monitoring bubble is guided into the liquid discharge pipe through the bubble containing chamber to be detected.

In a further implementation, a liquid feeding pipe joint and a liquid discharging pipe joint are respectively formed at the two ends of the liquid pipe flow passage, the liquid feeding pipe joint and the liquid discharging pipe joint are mutually communicated through the bubble accommodating chamber, and different height differences exist between the liquid feeding pipe joint and the liquid discharging pipe joint.

In still further implementations, the liquid supply pipe adapter port is located at a height within the bubble receiving chamber that is relatively lower than the liquid discharge pipe adapter port.

In a further implementation, one end of the liquid feeding pipe is implanted into the bubble accommodating chamber through the liquid feeding pipe joint.

In a further embodiment, the feed tube adapter is formed in the shape of a semicircular tube wall, and the open area of the feed tube adapter is smaller than the open notch.

In a further embodiment, the mouthpiece is formed on the same side end wall of the body as the open slot.

In a further implementation, the feed tube mouthpiece is located at a height relatively below the open slot.

In still further embodiments, the drain adaptor is formed as a tube bore.

In further embodiments, the liquid in the drain tube is driven by a driver to flow.

According to the technical means, the utility model has the advantages of: by means of the bubble screening technology, when the too large bubbles are generated in the liquid pipe carelessly, the too large bubbles can be smoothly screened into monitoring bubbles with proper volumes, so that the detection accuracy of the small-flow leaked gas is improved.

Detailed Description

First, referring to fig. 1 and fig. 2, a preferred embodiment of the present invention is disclosed, and the bubble separator in the liquid tube provided by the present invention is provided with a liquid tube flow passage 31 and a bubble accommodating chamber 32 formed in a container body 30. Wherein:

the liquid pipe flow channel 31 has two ends respectively extending 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 41 for supplying the bubbles 10, the liquid discharge pipe joint 35 is used for connecting a liquid discharge pipe 42 for detecting the discharged bubbles 10, the liquid supply pipe joint 34 is made into a semicircular pipe wall shape in practice, and the liquid discharge pipe joint 35 is made into a pipe hole shape in practice. 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 liquid pipe flow passage 31 extends through the bubble accommodating chamber 32, the liquid supply pipe connection port 34 and the liquid discharge pipe connection port 35 are communicated with each other through the bubble accommodating chamber 32, and the liquid supply pipe 41 is further communicated with the liquid discharge pipe 42 through the bubble accommodating chamber 32. The end wall of the container body 30 forming the liquid supply pipe joint 34 is also provided with an open notch 33 connected with the bubble accommodating chamber 32, the height of the open notch 33 in the bubble accommodating chamber 32 is relatively higher than that of the liquid supply pipe joint 34, and the opening area of the liquid supply pipe joint 34 is smaller than that of the open notch 33, so that the bubbles 10 can quickly leave the bubble accommodating chamber 32 through the open notch 33 after entering the bubble accommodating chamber 32 from the liquid supply pipe 41, 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 41 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 42, thereby facilitating the entry of part of the bubbles 10 (i.e. the monitoring bubbles 13) into the liquid discharge tube 42.

Referring to fig. 3 to 5, the operation illustration of the present invention is sequentially disclosed, which illustrates that the container body 30 and the liquid feeding tube 41 connected to the container body 30 are immersed in the liquid 20 in a liquid tank 50, the liquid tank 50 can be enclosed by a transparent or opaque tank wall, the liquid tank 50 is connected to the atmosphere and filled with the liquid 20, and the density of the liquid 20 in the liquid tank 50 is the same as that of the liquid 20 in the liquid feeding tube 41. The gas conduit 60 for guiding the leaking gas is connected to the liquid feeding tube 41, so that the gas in the gas conduit 60 generates bubbles 10 in the liquid 20 in the liquid feeding tube 41, and at the same time, the liquid 20 in the liquid discharging tube 42 is driven by a driver (not shown) to flow, so as to drive the liquid 20 in the liquid feeding tube 41 to follow the flow, so that the bubbles 10 in the liquid feeding tube 41 are driven by the liquid 20 to flow from the liquid feeding tube 41 to the bubble accommodating chamber 32 (as shown in fig. 3), wherein the bubbles 11 include the excessive bubbles 11 accumulated in the liquid feeding tube 41, and the volume of the excessive bubbles 11 is larger than the preset bubble volume range.

When the excessive bubbles 11 enter the bubble accommodating chamber 32 through the liquid feeding tube 41 (as shown in fig. 4), 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 50 due to the buoyancy thereof.

Since the bubble volume of the monitoring bubble 13 is smaller than the excess bubble 12, that is, the buoyancy of the monitoring bubble 13 is smaller than the excess bubble 12, when the liquid 20 in the drainage tube 42 flows by the driving of the driver, a negative pressure state is formed in the drainage tube 42, so that the monitoring bubble 13 with smaller buoyancy is sucked into the drainage tube 42 (as shown in fig. 5), and thus, the bubble volume of the bubble 10 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.
