Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and more particularly to a portable hydrogen sulfide gas detection device. Background Art

[0002] Hydrogen sulfide (H2S) is a colorless, toxic gas with a strong pungent odor, commonly found in many industries such as petroleum, natural gas, agriculture, and chemicals. The primary purpose of hydrogen sulfide gas detection is to protect the lives of personnel, to promptly detect and avoid the hazards caused by hydrogen sulfide gas leakage, and secondly to protect the stability and health of the ecological environment, and to take timely measures to prevent the spread of hydrogen sulfide. Therefore, accurate and timely detection and monitoring of hydrogen sulfide gas is particularly important.

[0003] There are many places or environments where hydrogen sulfide gas needs to be detected, such as the metallurgical industry, geothermal power stations, and volcanic activities. In many environments, it is more convenient to use a portable hydrogen sulfide gas detector for detection. Take a chemical plant as an example. The gas temperature generated during the production process of the chemical plant is relatively high, and the sensors and other components in the portable hydrogen sulfide gas detector are greatly affected by temperature. The operating temperature range of most portable hydrogen sulfide gas detection instruments is usually between -20°C and 50°C. When the temperature of the gas to be tested is too high, it not only affects the test results, but also easily damages the equipment. Gas containing hydrogen sulfide may contain other impurities, such as sulfur particles and microparticles. These impurities may enter the portable hydrogen sulfide gas detection instrument and damage the components. Therefore, it is necessary to propose a portable hydrogen sulfide gas detection device to solve the above problems. Summary of the invention

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. During the detection of hydrogen sulfide gas, the gas to be tested is guided through the air inlet hopper and the vent pipe. A number of heat-conducting strips and heat-conducting sheets are evenly arranged in the vent pipe and the air inlet hopper. The heat-conducting strips and heat-conducting sheets have good thermal conductivity, which can not only circulate the gas in partitions, but also absorb and conduct the heat in the gas. The cooling treatment is completed during the gas flow process, so that the temperature of the gas to be tested is reduced to meet the detection conditions of the detector; while collecting the gas to be tested, the cooling water is circulated on the outside of the vent pipe and the air inlet hopper through the pumping mechanism. The outsides of the heat-conducting strips and heat-conducting sheets extend to the outside of the vent pipe and the air inlet hopper respectively, and can fully contact with the cooling water in the space between the vent pipe and the water outlet pipe and inside the water distribution pipe. The heat is transferred by the circulating cooling water to ensure that the heat-conducting strips and heat-conducting sheets continuously absorb and conduct the heat in the gas.

[0022] 2. A filter plate is also installed in the ventilation pipe. The filter plate can not only filter out other impurities in the gas to prevent inaccurate monitoring data, but also can drive the rotating rod to rotate by pushing the rotating blade when the gas passes through the filter plate. The rotating rod drives the mixing mechanism to move, so that the reciprocating plate and the spoiler plate reciprocate in the buffer ring. The reciprocating plate drives the cooling water in the buffer ring to disturb horizontally, and the spoiler plate drives the cooling water in the buffer ring to disturb vertically. The horizontal disturbance and the vertical disturbance cooperate with each other to accelerate the mixing of unevenly hot and cold water in the buffer ring, so that the heat of the cooling water is evenly distributed, so as to facilitate the subsequent cooling water cooling treatment; the rotation of the rotating rod will also drive the boosting mechanism to pressurize the cooling water in the return pipe, so that the cooling water is pressurized through the expansion port, and the pressure change when the cooling water flows out of the expansion port is used to quickly cool the cooling water.

[0023] 3. After the gas detection is completed, remove the mounting block, and the control mechanism can automatically control the sealing door and the paddle plate. The paddle plate drives the seal on the sealing plate to close the ventilation groove, and the sealing door slides to open the water guide groove. The cooling water enters the filter plate through the water guide groove to backwash the filter plate; and the backwashing cooling water drives the scraper and the cleaning strip to rotate through the rotating blade to clean the surface of the filter plate, and clean the filter plate from the inside to the outside to ensure the ventilation rate of the filter plate.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0043] Example 1, please refer to Figure 1-16 As shown, the present invention discloses a portable hydrogen sulfide gas detection device, including a main body mechanism 1, the main body mechanism 1 includes a detector 11, the detector 11 is provided with a mounting groove 12, and the mounting groove 12 is respectively provided with a top column 13 and a detection port 14;

[0044] The mounting groove 12 is provided with a collecting mechanism 2, and the collecting mechanism 2 includes a mounting block 21 inserted into the mounting groove 12, a motor 22 and a pump body 23 are installed in the mounting block 21, the output end of the motor 22 is connected to one end of the impeller shaft inside the pump body 23, and the pump body 23 is respectively connected with an air inlet end 24 and an air outlet end 25, and a vent pipe 26 is installed on the top surface of the mounting block 21, and the bottom end of the vent pipe 26 is connected with the air inlet end 24, and the inside of the vent pipe 26 is evenly provided with heat conducting strips 28;

[0045] A cooling mechanism 3 is provided inside the mounting block 21. The cooling mechanism 3 includes a water storage chamber 31 and a water return chamber 32 provided inside the mounting block 21. The water storage chamber 31 is connected to the water return chamber 32. A water outlet pipe 34 is sleeved on the outside of the vent pipe 26. A buffer ring 35 is provided on the outside of the top of the water outlet pipe 34. A water return pipe 39 is provided inside the vent pipe 26. A plurality of through pipes 38 are connected between the top of the water return pipe 39 and the buffer ring 35. The plurality of through pipes 38 penetrate the vent pipe 26, and the water return chamber 32 is connected to the bottom of the water return pipe 39.

[0046] A filter mechanism 6 is installed inside the ventilation pipe 26. The filter mechanism 6 includes a filter plate 61 installed inside the top of the ventilation pipe 26. The filter plate 61 is rotatably connected to a rotating rod 62, and the rotating rod 62 penetrates the filter plate 61. A rotating blade 63 is fixed to the part of the rotating rod 62 inside the filter plate 61. A scraper 64 and a cleaning strip 65 are symmetrically installed on the top of the rotating rod 62. The scraper 64 and the cleaning strip 65 abut against the top surface of the filter plate 61.

[0047] A mixing mechanism 8 is installed at the bottom end of the rotating rod 62, and the mixing mechanism 8 includes a resistance plate 81 installed at the bottom end of the rotating rod 62, a sliding rod 82 is slidably connected between the vent pipe 26 and the water outlet pipe 34, and the sliding rod 82 passes through the vent pipe 26 and the water outlet pipe 34, a push block 84 is fixed at one end of the sliding rod 82, the resistance plate 81 resists the push block 84, and a reciprocating plate 85 is fixed at the other end of the sliding rod 82, and the reciprocating plate 85 is slidably connected in the buffer ring 35.

[0048] Before detecting hydrogen sulfide gas, first insert the mounting block 21 into the mounting groove 12, the air outlet end 25 is connected to the detection port 14 in the mounting groove 12, and the top column 13 in the mounting groove 12 is inserted into the mounting block 21, so that the control mechanism 5 slides, thereby releasing the interference with the dial plate 75 and the third wedge block 69, and then, under the action of the torsion spring, the sealing plate 73 inside the outer plate 71 rotates, so that the seal 74 no longer closes the ventilation groove 72, and the ventilation grooves 72 of the upper and lower layers of the outer plate 71 are connected to each other. The outer plate 71 is divided into two layers, the sealing plate 73 is rotatably connected to the middle of the outer plate 71 by the torsion spring, and the size of the seal 74 is sufficient to close the ventilation groove 72; under the push of the second spring 68, the sealing door 67 slides to close the water guide groove 66 (a through groove is provided on the wall of the ventilation pipe 26, the sealing door 67 slides in the groove, and the second spring 68 is installed in the groove). The motor 22 drives the pump body 23 to work. The pump body 23 is composed of an outer shell, an impeller and an impeller shaft. The output end of the motor 22 drives the impeller to rotate in the outer shell through the impeller shaft, and the booster plate 41 passes through the side of the outer shell and is installed at the other end of the impeller shaft. The pump body 23 generates suction, and external gas enters from the air inlet hopper 27, and then enters the detection port 14 from the ventilation pipe 26, the air inlet end 24, the pump body 23 and the air outlet end 25 for detection.

[0049] When the gas passes through the air intake hopper 27 and the vent pipe 26, it is evenly divided into several air flows by the heat conductive sheets 29 and the heat conductive strips 28 provided in the air intake hopper 27 and the vent pipe 26. Moreover, the heat conductive sheets 29 and the heat conductive strips 28 have good thermal conductivity. When the gas contacts the heat conductive sheets 29 and the heat conductive strips 28, the heat of the gas will be absorbed and conducted away by the heat conductive sheets 29 and the heat conductive strips 28, thereby reducing the gas temperature to within the tolerance range of the detector 11.

[0050] While the pump body 23 inhales air, it pumps the cooling water in the water storage chamber 31 into the space between the vent pipe 26 and the water outlet pipe 34 through the pump mechanism 4 (the inner diameter of the water outlet pipe 34 is larger than the outer diameter of the vent pipe 26, and there is a space for the cooling water to flow between the water outlet pipe 34 and the vent pipe 26). The cooling water in the space between the vent pipe 26 and the water outlet pipe 34 flows continuously, and continuously flows into the several water distribution pipes 36 outside the air inlet bucket 27, and then enters the buffer ring 35 from the return pipe 37. The water in the buffer ring 35 enters the return pipe 39 from the through pipe 38, and enters the return water chamber 32 from the return pipe 39. The water in the return water chamber 32 is mixed with the water in the water storage chamber 31 again, and the cooling water circulates in the above-mentioned pipelines. The outer sides of the heat conductive strip 28 and the heat conductive sheet 29 extend to the outer sides of the vent pipe 26 and the air inlet bucket 27 respectively, and are in direct contact with the water in the space between the vent pipe 26 and the water outlet pipe 34 and inside the water distribution pipe 36. The flowing water in the space between the ventilation pipe 26 and the water outlet pipe 34 takes away the heat conducted by the thermal strip 28, so that the thermal strip 28 can continuously absorb the heat of the gas; similarly, the water flowing in the water distribution pipe 36 takes away the heat in the thermal conductive sheet 29, and also enables the thermal conductive sheet 29 to continuously absorb the heat of the gas, thereby quickly reducing the temperature of the gas passing through the air intake scoop 27 and the ventilation pipe 26.

[0051] The gas to be tested contains a lot of impurities, which will contaminate and damage the detector 11 when entering the detection port 14. Therefore, the gas in the air inlet hopper 27 will pass through the filter plate 61 when entering the ventilation pipe 26. The filter plate 61 blocks the impurities in the gas to prevent the detector 11 from being contaminated.

[0052] When the gas enters the air intake hopper 27, there may be a problem of uneven distribution. Therefore, the gas in the air intake hopper 27 and the ventilation pipe 26 may have different temperatures at different positions, and the corresponding heat conducting strips 28 and heat conducting sheets 29 absorb different amounts of heat, which leads to uneven temperature distribution in the cooling water. Therefore, when the gas passes through the filter plate 61, the rotating blade 63 drives the rotating rod 62 to rotate, and the rotating rod 62 drives the contact plate 81 to rotate. The contact plate 81 is composed of a circular plate and a plurality of supporting rods, and the plurality of supporting rods are evenly fixed on the outer side of the circular plate. During the rotation of the contact plate 81, it will intermittently contact and push the push block 84, and the push block 84 drives the slide bar 82 to slide. The slide bar 82 compresses the third spring 83, and the sliding of the slide bar 82 will push the reciprocating plate 85 to slide in the buffer ring 35, thereby pushing the water flow in the buffer ring 35 to horizontally disturb the water flow. When the reciprocating plate 85 slides, the gear 88 is driven to rotate through the rack 86 (the shaft frame 87 is composed of a bracket and a shaft, the shaft rotates on the bracket, and the gear 88 is installed on the shaft), the gear 88 drives the shaft to rotate, the shaft drives the spoiler 89 to swing, and the spoiler 89 drives the water flow in the buffer ring 35 to vertically disturb, and the horizontal disturbance cooperates with the vertical disturbance to accelerate the mixing of unevenly hot and cold water in the buffer ring 35, so that the heat of the water in the buffer ring 35 is evenly distributed, so that the subsequent cooling water can be cooled.

[0053] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 16 The collecting mechanism 2 further includes an air intake hopper 27 fixed to the end of the vent pipe 26 , and a plurality of heat conducting plates 29 are evenly arranged on the inner side of the air intake hopper 27 .

[0054] The cooling mechanism 3 also includes a water inlet 33 arranged on the surface of the mounting block 21, the water inlet 33 is connected to the connecting point between the water storage chamber 31 and the return water chamber 32, a plurality of water distribution pipes 36 are evenly arranged on the outside of the air inlet hopper 27, the bottom ends of the plurality of water distribution pipes 36 are connected to the space between the ventilation pipe 26 and the water outlet pipe 34, the top end of each water distribution pipe 36 is connected to a return pipe 37, and the bottom ends of the plurality of return pipes 37 are connected to the buffer ring 35, and an expansion port 391 is provided inside the return water pipe 39.

[0055] A pumping mechanism 4 is also installed inside the mounting block 21. The pumping mechanism 4 includes a boosting disk 41 rotatably connected to the side of the pump body 23, and a boss 42 is eccentrically fixed on the boosting disk 41. A pumping cavity 44 is provided inside the mounting block 21. The top of the pumping cavity 44 is respectively connected to the water storage cavity 31, the vent pipe 26 and the space between the water outlet pipe 34. A piston 46 is slidably connected inside the pumping cavity 44. A connecting rod 45 is fixed to the bottom of the piston 46. An adjusting frame 43 is fixed to the bottom end of the connecting rod 45, and the boss 42 is slidably connected in the adjusting frame 43.

[0056] The mixing mechanism 8 also includes a third spring 83 sleeved on the slide rod 82, a rack 86 is provided on the side of the reciprocating plate 85, a rotating shaft frame 87 is installed inside the buffer ring 35, a gear 88 is installed on the rotating shaft frame 87, the rack 86 is meshed with the gear 88, and a spoiler 89 is installed on the rotating shaft frame 87.

[0057] A boosting mechanism 9 is installed inside the return pipe 39, and the boosting mechanism 9 includes a push plate 93 slidably connected to the inside of the return pipe 39, a pressure platform 94 is fixed to the top surface of the push plate 93, a turntable 91 is rotatably connected to the bottom surface of the contact disk 81, a fourth spring 92 is installed on the bottom surface of the turntable 91, and the bottom end of the fourth spring 92 is installed on the top surface of the push plate 93, a pressure column 95 is eccentrically fixed to the bottom surface of the contact disk 81, and the pressure column 95 contacts the pressure platform 94.

[0058] The mounting block 21 is provided with a water inlet 33 for replenishing cooling water.

[0059] When the pump body 23 sucks in gas, it drives the booster plate 41 to rotate, and the booster plate 41 drives the convex column 42 to rotate eccentrically, and the convex column 42 slides in the adjustment frame 43, and at the same time drives the adjustment frame 43 to slide up and down (as shown in the attached figure). Figure 4 As shown in FIG. 4 , the adjusting frame 43 drives the piston 46 to slide up and down in the pump liquid chamber 44 through the connecting rod 45. Check valves are provided at the connection between the water storage chamber 31 and the pump liquid chamber 44, at the connection between the pump liquid chamber 44 and the vent pipe 26 and the outlet pipe 34, and in the through pipe 38. During the downward sliding of the piston 46, suction is generated, the check valve at the connection between the pump liquid chamber 44 and the vent pipe 26 and the outlet pipe 34 is closed, the check valve at the connection between the water storage chamber 31 and the pump liquid chamber 44 is opened, and the cooling water in the water storage chamber 31 enters the pump liquid chamber 44; during the upward sliding of the piston 46, the check valve at the connection between the water storage chamber 31 and the pump liquid chamber 44 is closed, the check valve at the connection between the pump liquid chamber 44 and the vent pipe 26 and the outlet pipe 34 is opened, and the cooling water in the pump liquid chamber 44 enters the space between the vent pipe 26 and the outlet pipe 34, thereby providing power to allow the cooling water to flow continuously in the pipeline and circulate back and forth.

[0060] In order to prevent the cooling water temperature from increasing, an expansion port 391 is provided in the return pipe 39. The cooling water will be compressed when passing through the expansion port 391. When the water flows out of the expansion port 391, the space suddenly increases from small to large, and the compressed cooling water releases pressure instantly, thereby rapidly cooling down. In addition, when the rotating rod 62 drives the contact plate 81 to rotate (a reducer is installed at the bottom end of the rotating rod 62, and the top of the contact plate 81 is installed at the bottom end of the reducer), the pressure column 95 at the bottom of the contact plate 81 moves in a circle. The pressure column 95 slides on the top of the pressure platform 94 and the push plate 93. When the pressure column 95 rotates to the high position of the pressure platform 94, the push plate 93 slides downward (attached Figure 7The pressure of the first spring 92 is used to press the cooling water in the return pipe 39 downwards, and the one-way valve in the through pipe 38 is closed. Pressurizing the cooling water can increase the flow rate of the water, thereby increasing the pressure of the cooling water flowing out of the expansion port 391, and further improving the cooling efficiency of the cooling water. After the pressure column 95 rotates to disengage from the pressure platform 94, the fourth spring 92 pulls back the push plate 93 to reset the push plate 93. During the reset of the push plate 93, the one-way valve in the through pipe 38 is opened, and the cooling water continues to flow into the return pipe 39. During the rotation of the abutment plate 81, the rotating plate 91 connected to the top of the fourth spring 92 is stationary at the bottom of the abutment plate 81.

[0061] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 16 The top column 13 abuts against the control mechanism 5, which includes a long rod 51 slidably connected to the space between the vent pipe 26 and the water outlet pipe 34. The long rod 51 is also slidably connected to the mounting block 21, and the top column 13 is inserted into the mounting block 21 and abuts against the long rod 51. The long rod 51 and the mounting block 21 are elastically connected by a first spring 52. A first wedge block 53 is fixed to the top of the long rod 51, and a second wedge block 54 is fixed to the side of the first wedge block 53.

[0062] The filtering mechanism 6 also includes a plurality of water guide grooves 66 arranged inside the filter plate 61, the inner ends of the plurality of water guide grooves 66 are connected to each other, and the outer ends of the plurality of water guide grooves 66 pass through the side of the filter plate 61, a sealing door 67 is slidably connected to the wall of the ventilation pipe 26, a second spring 68 is installed on the sealing door 67, a third wedge block 69 is fixed to the outer side of the sealing door 67, and the second wedge block 54 abuts against the third wedge block 69, and a honeycomb plate 691 is installed at the connection point of the plurality of water guide grooves 66, and the honeycomb plate 691 is at the bottom of the rotating blade 63.

[0063] A closing mechanism 7 is installed at the bottom of the filter disc 61, and the closing mechanism 7 includes an outer plate 71 installed at the bottom of the filter disc 61, and a plurality of ventilation grooves 72 are penetrated on the outer plate 71. A sealing plate 73 is rotatably connected inside the outer plate 71, and a plurality of sealing strips 74 are fixed on the sealing plate 73. A paddle plate 75 is fixed on the side of the ventilation groove 72, and the first wedge block 53 abuts against the paddle plate 75.

[0064] When the top column 13 is inserted into the mounting block 21, it pushes the long rod 51 in the mounting block 21 to slide upward (as shown in the attached figure). Figure 3As shown in the orientation, the same below), the long rod 51 stretches the first spring 52 and drives the first wedge block 53 and the second wedge block 54 at the top thereof to slide upward. After the first wedge block 53 and the second wedge block 54 move, they no longer squeeze the corresponding paddle plate 75 and the third wedge block 69. After the paddle plate 75 is not under pressure, under the elastic force of the torsion spring, the sealing plate 73 rotates inside the outer plate 71, driving the seal 74 to deflect, and the seal 74 no longer blocks the ventilation groove 72; similarly, the second spring 68 pushes the sealing door 67 to slide, closing the water guide groove 66, and the cooling water in the space between the ventilation pipe 26 and the water outlet pipe 34 cannot enter the water guide groove 66.

[0065] During the gas detection process, when the gas passes through the filter disc 61 , impurities in the gas will remain on the filter disc 61 . If the impurities are not cleaned for a long time, the gas passing rate of the filter disc 61 will be reduced. After the gas detection is completed, the mounting block 21 is removed from the mounting groove 12, the top column 13 is detached from the mounting block 21, the first spring 52 drives the long rod 51 to reset, and the long rod 51 drives the first wedge block 53 and the second wedge block 54 at its top to slide downward. During this process, the first wedge block 53 and the second wedge block 54 respectively squeeze the shift block and the third wedge block 69, and the shift block drives the sealing plate 73 to rotate inside the outer plate 71, and the sealing plate 73 drives the seal 74 to rotate, and the ventilation groove 72 is closed again, thereby closing the ventilation pipe 26; the second wedge block 54 squeezes the third wedge block 69, and the third wedge block 69 drives the sealing door 67 to slide, and the sealing door 67 compresses the second spring 68 while opening the water guide groove 66, and the water in the space between the ventilation pipe 26 and the water outlet pipe 34 enters the filter disc 61 through the water guide groove 66. Since the bottom of the filter disc 61 is blocked by the sealing mechanism 7, the water entering the filter disc 61 flows upward, thereby backwashing out the impurities in the filter disc 61 to ensure the cleanliness of the inside of the filter disc 61. Since there is a connection point of several water guide grooves 66 below the rotating blade 63, water can flow smoothly, while the resistance at other positions in the filter plate 61 is relatively large, the flow speed of water in the water guide groove 66 is greater than the flow speed in the filter plate 61, and a honeycomb plate 691 is also installed at the connection point of several water guide grooves 66 to increase the pressure of the water flow in the water guide groove 66. Therefore, the upward flow of cooling water in the water guide groove 66 can drive the rotating blade 63 to rotate, and the rotating blade 63 drives the scraper 64 and the cleaning strip 65 on the top surface of the filter plate 61 to rotate through the rotating rod 62. The scraper 64 scrapes off impurities on the top surface of the filter plate 61, and the cleaning strip 65 sweeps away impurities on the surface of the filter plate 61, thereby further improving the cleaning effect.
