[0008] After the calibration expansion seat is filled with gas, it first expands vertically until it fits tightly against the detection head, and then sprays the calibration gas through the standard gas outlet at the top center. When the gas is continuously injected, it expands horizontally until the detection chamber is filled. At the same time, the negative pressure generated by the flow of hydrogen sulfide gas is used to suck out the residual gas in the detection chamber through the negative pressure suction pipe.

[0009] The expansion process of the calibration expansion seat is divided into two stages: the first stage is vertical expansion to complete the calibration of the detector head, and the second stage is lateral expansion combined with negative pressure suction to achieve gas replacement in the detection chamber.

[0034] like Figure 1 - Figure 10 As shown, a hydrogen sulfide production detection device includes: a detector body 11, a zero-residual ventilation mechanism 2 is provided at the connection end of the detector body 11 for removing residual gas after each detection; the zero-residual ventilation mechanism 2 includes:

[0035] The detection chamber 21 has a detection head at the top and an L-shaped negative pressure suction pipe 31 at the bottom. One end of the negative pressure suction pipe 31 is connected to the detection chamber 21, and the other end extends to the hydrogen sulfide gas flow path;

[0036] The calibration expansion seat 23 is provided in the detection chamber 21 and is located directly below the detection head, and is connected to the external gas supply device of the detector body 11;

[0037] After the calibration expansion seat 23 is filled with gas, it first expands vertically until it fits tightly against the detection head, and then sprays calibration gas through the standard gas outlet 27 at the top center. When the gas is continuously injected, it expands horizontally until it fills the detection chamber 21. At the same time, the negative pressure generated by the flow of hydrogen sulfide gas is used to suck out the residual gas in the detection chamber 21 through the negative pressure suction pipe 31.

[0038] The expansion process of the calibration expansion seat 23 is divided into two stages: the first stage is vertical expansion to complete the calibration of the detection head, and the second stage is lateral expansion combined with negative pressure suction to achieve gas replacement in the detection chamber 21.

[0039] Zero residual ventilation mechanism 2: Through a two-stage expansion design, the first stage of vertical expansion ensures that the calibration gas is accurately sprayed onto the detection head, improving calibration accuracy; the second stage of lateral expansion is combined with negative pressure suction to achieve complete replacement of the gas in the detection chamber 21, avoiding residual gas from interfering with subsequent detection and ensuring detection reliability.

[0040] The zero residual ventilation mechanism 2 also includes a foldable base 22, the diameter of the foldable base 22 is smaller than the internal diameter of the detection chamber 21, and an air intake plate 25 is fixedly provided at the bottom of the foldable base 22. A plurality of air intake holes 26 are opened on the air intake plate 25, and the outer ring of the air intake plate 25 is fixedly connected to the inner wall of the detection chamber 21.

[0041] The calibration expansion seat 23 includes an expansion rubber cylinder 231, an elastic band 232 and a head plate 233. The outer wall array of the expansion rubber cylinder 231 has several elastic bands 232. The top of the expansion rubber cylinder 231 is fixedly provided with a head plate 233. The head plate 233 and the expansion rubber cylinder 231 form an integrated structure. The expansion rubber cylinder 231 is fixed in the retractable base 22.

[0042] Calibration expansion seat 23 and head plate 233: The head plate 233 has a diameter larger than the detection head. It cooperates with the supporting gas column 29 and the residual removal hole 202 to remove the residual gas in the standard gas outlet 27 through negative pressure suction during expansion, preventing the calibration gas from mixing with the residual gas and improving the calibration accuracy.

[0043] The air inlet end of the expansion rubber cylinder 231 is provided with a standard gas injection pipe 24, the air inlet end of the standard gas injection pipe 24 is connected to the gas supply equipment, the standard gas outlet 27 is provided at the center position of the head plate 233, and the air inlet end of the standard gas outlet 27 is connected to the air injection pipe 28, and the air injection pipe 28 is routed along the inside of the standard gas injection pipe 24 to the outside of the detection chamber 21.

[0044] The internal upper and lower walls of the head plate 233 are fixedly provided with support plates 201, and a plurality of support air columns 29 are arrayed between the two support plates 201, and the plurality of support air columns 29 are interconnected. The support air columns 29 are hollow structures, and the air inlet end of the support air column 29 is arranged on the inner wall of the standard air outlet 27 as a residual removal hole 202.

[0045] The diameter of the head plate 233 is larger than the diameter of the detection head, the diameter of the expansion rubber cylinder 231 in the vertical expansion state is larger than the diameter of the head plate 233, and the centers of the head plate 233, the expansion rubber cylinder 231 and the retractable base 22 are all aligned with the center of the detection head.

[0046] The negative pressure suction pipe 31 passes through the air inlet plate 25 . A lifting head 33 is slidably provided at the air inlet end of the negative pressure suction pipe 31 . The outer wall of the lifting head 33 is provided with a plurality of suction holes 35 for inhaling the gas in the detection chamber 21 .

[0047] Negative pressure suction tube 31 and lifting head 33: The L-shaped design cooperates with the negative pressure generated by the flow of hydrogen sulfide gas to actively suck the gas in the detection chamber 21; the lifting head 33 expands and rises with the calibration expansion seat 23, sucking the residual gas at the top, and the air bag 34 and the air blocking bag 36 work together to block the suction hole 35 to prevent external gas from flowing back during calibration and maintain the sealing of the detection chamber 21.

[0048] The foldable base 22 and the air intake plate 25: The diameter of the air intake plate 25 is smaller than that of the detection chamber 21, and cooperates with the air intake hole 26 to evenly introduce the gas to be tested, reducing airflow turbulence; the foldable base 22 fixes the calibration expansion seat 23 to ensure that the expansion direction is vertical, thereby improving structural stability.

[0049] An air-blocking bag 36 is fixedly provided on the inner wall of each of the suction holes 35 , and an air bag 34 is fixedly provided on the top wall of the lifting head 33 . The air bag 34 is communicated with the plurality of air-blocking bags 36 .

[0050] A force-bearing arm 39 is fixedly provided on one side of the lifting head 33 close to the detection head. The force-bearing arm 39 is Z-shaped. When the calibration expansion seat 23 expands, it pushes the force-bearing arm 39 upward, so that the lifting head 33 rises to the highest point of the detection chamber 21.

[0051] The inner wall of the negative pressure suction pipe 31 is provided with several elastic ropes 38, the two ends of the several elastic ropes 38 are fixedly connected to the inner wall of the negative pressure suction pipe 31, and the middle section of the elastic rope 38 is in a relaxed state. A wind-swinging rope 32 is fixedly provided at the air outlet end of the negative pressure suction pipe 31, and several counterweight balls 37 are fixedly provided on the wind-swinging rope 32.

[0052] Wind-swept rope 32 and elastic rope 38: The gas flow drives the counterweight ball 37 to hit the inner wall of the negative pressure suction pipe 31, and the elastic rope 38 is impacted by the airflow to whip the pipe wall, automatically cleaning the residue in the pipe and extending the service life of the equipment.

[0053] When in use, the detector body 11 is installed on the hydrogen sulfide production and transportation pipeline. At this time, the detection chamber 21 is connected to the hydrogen sulfide production and transportation pipeline, and the negative pressure suction pipe 31 is directed towards the flow direction of the gas in the hydrogen sulfide production and transportation pipeline;

[0054] Hydrogen sulfide gas enters the detection chamber 21 through several air inlet holes 26. The detection head is in the detection chamber 21. When the detector body 11 performs hydrogen sulfide gas detection, the detection head is controlled to detect the gas entering the detection chamber 21. During this process, the gas in the hydrogen sulfide production and transportation pipeline flows through the negative pressure suction pipe 31 at high speed. At this time, a pressure difference is formed in the negative pressure suction pipe 31, thereby generating a certain suction force on the gas in the detection chamber 21, thereby extracting the gas in the detection chamber 21, which is conducive to the entry of fresh gas.

[0055] After the test is completed, as the negative pressure suction tube 31 gradually draws away the original gas in the test chamber 21 , the gas can be replenished into the test chamber 21 , so that the test chamber 21 is filled with newly replenished gas each time a test is performed.

[0056] When the detection head needs to be calibrated, gas is first injected into the expansion rubber cylinder 231 through the gas supply device outside the detection chamber 21, causing the expansion rubber cylinder 231 to gradually expand. As the gas increases, the expansion rubber cylinder 231 expands and rises from the inside of the retractable base 22 until the head plate 233 is tightly attached to the lower wall of the detection head. At this time, the expansion rubber cylinder 231 encounters resistance. As gas is continued to be injected, the expansion rubber cylinder 231 continues to expand, gradually filling the entire detection chamber 21, preventing new hydrogen sulfide gas from entering the detection chamber 21, and squeezing out the original gas in the detection chamber 21 as the expansion rubber cylinder 231 expands.

[0057] When the expansion rubber cylinder 231 is in close contact with the detection head, there is a certain space between the standard gas outlet 27 and the lower wall of the detection head. When the expansion rubber cylinder 231 expands, the head plate 233 is also inflated, and the two support plates 201 stretch the several supported gas columns 29, thereby sucking the original gas in the standard gas outlet 27 into the several supported gas columns 29 through the several residual holes 202. At this time, it is ensured that the original gas is completely cleared, and then the gas used for calibration is injected into the gas injection pipe 28 through the external gas supply equipment.

[0058] When the expansion rubber cylinder 231 expands upward and reaches the position of the force arm 39, it will push the lifting head 33 to rise as the expansion rubber cylinder 231 rises, and the suction hole 35 rises accordingly, which is conducive to extracting the gas at the top of the detection chamber 21, until the lifting head 33 is pressed against the upper wall of the detection chamber 21, squeezing the gas in the airbag 34 into the air-blocking bag 36, causing it to expand, blocking the suction hole 35, isolating the external suction force, and reducing the intake of new gas.

[0059] After calibration, the gas in the expansion rubber cylinder 231 is extracted to shrink it, and the expansion rubber cylinder 231 is pulled back into the retractable base 22 through the elastic band 232, and the old gas sucked into the supporting air column 29 is ejected, which does not affect subsequent detection.

[0060] When the gas passes through the inside and outside of the negative pressure suction pipe 31, the wind-swung rope 32 swings with the flow of gas, and the counterweight ball 37 hits the inner wall of the negative pressure suction pipe 31, which plays a role in cleaning the inner wall of the negative pressure suction pipe 31. The elastic rope 38 will whip the inner wall of the negative pressure suction pipe 31 under the impact of the gas, which can also clean the negative pressure suction pipe 31.

[0061] Working steps:

[0062] Installation and connection: Install the detector body 11 on the hydrogen sulfide production and transportation pipeline, connect the detection chamber 21 with the pipeline, and point the negative pressure suction pipe 31 in the direction of gas flow to ensure that the airflow path is unobstructed.

[0063] Normal detection: Hydrogen sulfide gas enters the detection chamber 21 through the air inlet 26, and the detection head detects the gas concentration in real time; the negative pressure suction pipe 31 uses the gas flow to negatively suction the gas in the detection chamber 21, promoting the continuous replenishment of fresh gas.

[0064] Residual gas removal: After the test is completed, the negative pressure suction pipe 31 continues to suck, combined with the natural flow of gas, to discharge the residual gas in the test chamber 21, preparing a clean environment for the next test.

[0065] Detection head calibration: The gas supply equipment injects gas into the calibration expansion seat 23. In the first stage, vertical expansion makes the head plate 233 close to the detection head, and the standard gas outlet 27 sprays calibration gas. In the second stage, horizontal expansion fills the detection chamber 21, and the residual gas is completely replaced by negative pressure suction. At the same time, the gas column 29 is supported to clear the residual gas from the standard gas outlet 27 through the residual removal hole 202.

[0066] Calibration reset: exhaust the gas in the calibration expansion seat 23, pull it back to the closing base 22 with the elastic band 232, prop up the air column 29 to release the old gas inhaled; the lifting head 33 shrinks and descends with the calibration expansion seat 23, the air bag 34 and the air blocking bag 36 return to their original state, unblock the suction hole 35, and the detection chamber 21 returns to the test state.

[0067] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
