[0025] Example 1

[0026] A safety gas-enhancing and odor-adding device for a gas outlet main, such as Figures 1-9 As shown, it includes a connecting main pipe 1, with flanges 2 fixedly connected to both ends of the connecting main pipe 1. An inclined air inlet pipe 31 is fixedly connected to the side wall of the connecting main pipe 1, and an air outlet pipe 32 is fixedly connected to the side wall of the connecting main pipe 1. A mixing tank 33 is fixedly connected between the air outlet pipe 32 and the inclined air inlet pipe 31. The connecting main pipe 1 is connected to the inclined air inlet pipe 31, the air outlet pipe 32, and the mixing tank 33. A mixing mechanism is provided on the mixing tank 33, which is used to initially mix the odorant with natural gas. An air intake mechanism is provided inside the connecting main pipe 1, which is used to divert a portion of the natural gas into the mixing tank 33.

[0027] The mixing mechanism comprises an atomizer 41 fixedly connected to the mixing tank 33, an interface pipe 42 fixedly connected to the upper portion of the atomizer 41, the interface pipe 42 being in communication with the atomizer 41, a gas pump 43 fixedly connected to the mixing tank 33, the gas inlet of the gas pump 43 being in communication with the atomizer 41, the gas outlet of the gas pump 43 being in communication with the mixing tank 33, a ring pipe 44 fixedly connected to the inner wall of the mixing tank 33, a plurality of holes being formed in the ring pipe 44, the upper portion of the ring pipe 44 being in communication with the gas outlet of the gas pump 43, and a plurality of nozzles 45 fixedly connected to the holes of the ring pipe 44.

[0028] The air inlet mechanism comprises two fixed plates 51, a limiting rod 52 slidingly connected to each of the two fixed plates 51, a reset spring 53 connected between the limiting rod 52 and the fixed plate 51, a sliding ring plate 54 fixedly connected between the two limiting rods 52, the sliding ring plate 54 being in contact with the inner wall of the connecting main pipe 1, a gas guide arc plate 55 fixedly connected to one side of the sliding ring plate 54, and the gas guide arc plate 55 being in contact with the inner wall of the connecting main pipe 1.

[0029] In actual work, the safety gas odorizing mainly adds odorant to natural gas, so that when natural gas is leaked, it will emit an unpleasant smell. First, the operator connects the connecting pipe 1 to the gas pipeline between the gas pipeline and other gas pipelines through the flange 2, then the operator connects the odorant through the interface pipe 42, then the odorant is atomized through the atomizer 41. Initially, the sliding ring plate 54 and the gas guide arc plate 55 block the connection between the inclined air inlet pipe 31 and the connecting pipe 1. Then the operator starts the gas pump 43, and begins to transport natural gas to the connecting pipe 1 from the end close to the inclined air inlet pipe 31 to the end close to the air outlet pipe 32. Then the gas pump 43 will pass the atomized odorant into the mixing tank 33 through the ring pipe 44 and the nozzle 45. When the connecting pipe 1 starts to transport natural gas, due to the flow of gas, the flowing natural gas will push the gas guide arc plate 55 and the sliding ring plate 54 to move horizontally together towards the end close to the air outlet pipe 32, and the return spring 53 is compressed. Then the horizontal movement of the sliding ring plate 54 will increase the blocked part of the connection between the inclined air inlet pipe 31 and the connecting pipe 1. In this way, the amount of gas flowing into the inclined air inlet pipe 31 can be changed according to the flow rate of the gas in the connecting pipe 1. The change of the amount of gas flowing into the inclined air inlet pipe 31 can change the amount of odorant carried out. The gas guide arc plate 55 is located below the connection between the inclined air inlet pipe 31 and the connecting pipe 1, so that a part of the natural gas transported by the connecting pipe 1 will enter the mixing tank 33 through the inclined air inlet pipe 31 under the guidance of the gas guide arc plate 55. A part of the natural gas entering the mixing tank 33 will mix with the odorant, and then pass through the air outlet pipe 32 into the connecting pipe 1 to further mix with the transported natural gas. The natural gas mixed with the odorant is transported to other gas pipelines. In this way, a part of the natural gas is diverted to the mixing tank 33 to be initially mixed with the odorant, and then mixed with the main natural gas. The flowing part of the natural gas is introduced into the mixing tank 33, which can mix the odorant under the action of the flow of gas, and the flowing gas can make the odorant more thoroughly introduced into the natural gas, and it is not easy to cause odorant residue.

[0030] Example 2

[0031] On the basis of example 1, as Figures 6-9As shown, the device further comprises a gas mixing mechanism arranged in the mixing tank 33, which is used to mix the odorant with a part of the natural gas. The gas mixing mechanism comprises a perforated plate 61 fixedly connected to the joint between the oblique gas inlet pipe 31 and the mixing tank 33. The perforated plate 61 is fixedly connected with a conical block 62 on one side and a plurality of connecting pipes 63 on the other side. A separation ring plate one 64 is fixedly connected between one side of the mixing tank 33 and the annular pipe 44. A separation ring plate two 65 is fixedly connected between the inner side wall of the mixing tank 33 and the annular pipe 44. A gas distribution plate 66 is fixedly connected to the inner wall of the separation ring plate two 65. The gas distribution plate 66 is connected to one side of the annular pipe 44. A plurality of support frames 67 are fixedly connected to the gas distribution plate 66. Two support frames 67 form a group. A rotating shaft 68 is rotatably connected between the two support frames 67 of each group. The rotating shaft 68 is provided with a conical surface at one end close to the perforated plate 61. The conical surface at one end of the rotating shaft 68 is used to guide the airflow. Two fan blades 69 are fixedly connected to each rotating shaft 68. The installation directions of the two fan blades 69 on the same rotating shaft 68 are opposite. The fan blades 69 are used to slow down the airflow and delay the mixing time. A plurality of gas guiding arc surface blocks 610 are fixedly connected between the gas distribution plate 66 and the separation ring plate two 65. A plurality of gas collecting funnel pipes 611 are fixedly connected between the gas guiding arc surface blocks 610 close to one side of the gas outlet pipe 32.

[0032] When a part of the natural gas enters the oblique gas inlet pipe 31, the part of the natural gas is divided into a plurality of gas streams by the perforated plate 61 and the connecting pipes 63. The conical block 62 can ensure that the natural gas can pass through the perforated plate 61 better. Each gas stream after being divided is mixed with the odorant sprayed by one of the spray heads 45. Then each mixed gas stream continues to flow and blows the fan blades 69, driving the fan blades 69 and the rotating shaft 68 to rotate. Since the installation directions of the two fan blades 69 on the same rotating shaft 68 are opposite, each gas stream is slowed down by the two fan blades 69. In this way, the mixing time of the natural gas and the odorant in each gas stream is increased. The gas stream after passing through the fan blades 69 is guided by the gas guiding arc surface blocks 610. All the gas streams after being divided pass through the gas collecting funnel pipes 611 again and are compressed under the action of the gas collecting funnel pipes 611. Finally, the mixed gas stream passes through the gas outlet pipe 32 into the connecting main pipe 1. In this way, the natural gas and the odorant are divided into a plurality of small gas streams for mixing and then concentrated and compressed for mixing, which can make the natural gas and the odorant mix more fully.

[0033] Example 3

[0034] On the basis of Example 2, as Figures 2-3As shown, the device further comprises an air outlet mechanism arranged at the lower part of the air outlet pipe 32, which is used to pass the mixed odorant into natural gas, and comprises a rotating pipe 71 rotatably connected to the lower part of the air outlet pipe 32, wherein the air outlet pipe 32 is in communication with the rotating pipe 71, the lower part of the rotating pipe 71 is closed, and a plurality of inclined thin pipes 72 are fixedly connected to the side of the rotating pipe 71 and in communication with the rotating pipe 71, a connecting frame 73 is fixedly connected to the middle part of the rotating pipe 71, and a plurality of air scooping plates 74 are fixedly connected to the side of the connecting frame 73, which are used to drive the rotating pipe 71 and the inclined thin pipes 72 to rotate and spray the mixed natural gas.

[0035] The opening heights of the plurality of inclined thin pipes 72 are different.

[0036] A part of the natural gas is mixed with the odorant in the mixing tank 33, and then enters the rotating pipe 71 through the air outlet pipe 32, and at the same time, the gas flow of the natural gas delivered by the connecting main pipe 1 drives the air scooping plates 74 and the connecting frame 73 to rotate, and the rotation of the connecting frame 73 drives the rotating pipe 71 and the inclined thin pipes 72 to rotate, and a part of the natural gas mixed with the odorant flows out of the plurality of inclined thin pipes 72 and enters the natural gas in the connecting main pipe 1, and then the rotating pipe 71 and the inclined thin pipes 72 rotate together, and the mixed gas in the connecting main pipe 1 is more evenly distributed in the delivered natural gas, and since the inclined thin pipes 72 are in an inclined state, the natural gas in the connecting main pipe 1 is not easy to flow into the rotating pipe 71 through the inclined thin pipes 72.

[0037] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
