Description

Technical Field

[0001] The utility model relates to the technical field of natural gas station auxiliary equipment, in particular to a demisting device. Background Art

[0002] Natural gas storage and distribution stations are important sites for gasifying liquefied natural gas and transmitting it to users. They are often equipped with multiple vaporizers. The vaporizers need to gasify a large amount of natural gas every day, and a large amount of fog will be generated at the bottom of the vaporizer during the gasification process. At the same time, due to the flammable and explosive characteristics of natural gas, storage and distribution stations are generally closed, which makes it difficult for the air in the storage and distribution stations to circulate. Over time, the storage and distribution stations are generally surrounded by fog, and the extremely low visibility poses a great safety hazard to the inspection and unloading operations of the station personnel. In addition, the moisture in the fog will affect the life of the equipment in the storage and distribution station. Therefore, a defogger is generally installed next to the vaporizer. The existing defogger is only equipped with a fan on one side of the vaporizer, which has difficulty in attracting the fog on the other side of the vaporizer, resulting in low work efficiency. Utility Model Content

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] Example: Please refer to Figure 1-2A demisting device includes a duct 7, a heating chamber 8 and an exhaust pipe 9, which is the structure of a general demisting device. On this basis, the demisting device of the utility model also includes a first fan 3, a front fixing plate 2, a rear fixing plate 5 and a side plate 6. The front fixing plate 2 is located at the front side of the gasifier 1, and the first fan 3 is fixedly connected to the front fixing plate 2, and is used to blow the water mist around the gasifier 1 toward the heating chamber 8 from front to back. The rear fixing plate 5 is located at the rear side of the gasifier 1, and the duct 7 is fixedly connected to the rear fixing plate 5. In this embodiment, the first fan 3 is a hot air blower, which can preheat the water mist and accelerate the evaporation of water droplets that may exist on the surface of the gasifier 1 while blowing the water mist. Side plates 6 are provided on the left and right sides of the vaporizer 1, respectively, for forming a horizontally closed space around the vaporizer 1 with the front fixed plate 2 and the rear fixed plate 5. A heating plate 10 is provided on the ground around the vaporizer 1 and inside the space enclosed by the front fixed plate 2, the rear fixed plate 5, the left and right side plates 6, for heating the water falling on the ground to accelerate evaporation. Furthermore, a water mist detector 4 is fixedly connected to the side of the front fixed plate 2 facing the vaporizer 1, for detecting whether water mist is formed or not. The left and right side plates 6 are movable plates, and the left and right side plates 6 are respectively fixedly connected to the movable blocks of a long-stroke linear motor. When the water mist detector 4 detects the presence of water mist, the left and right side plates 6 move to enclose a space with the front plate and the rear plate, and a guide rail is provided on the ground, and the guide rail is located on the moving track of the side plate 6, for regulating and increasing the moving speed of the side plate 6. The conduit 7 is connected to the heating chamber 8, and a second fan 81 is fixedly connected in the heating chamber 8. A heating structure is provided below the second fan 81. In this embodiment, the heating structure is a heating resistor 82. The top of the heating chamber 8 is connected to the exhaust pipe 9. The second fan 81 attracts the water mist around the vaporizer 1 into the heating chamber 8. Under the action of the heating resistor 82, small water droplets in part of the water mist are vaporized, so that the water mist is effectively reduced to a certain extent. The remaining part of the water mist and air are drawn into the exhaust pipe by the second fan 81 for discharge.

[0020] Working principle of this embodiment: This embodiment provides a demisting device. While the second fan 81 attracts the water mist around the vaporizer 1 into the heating chamber 8 for heating, the first fan 3 blows away the water mist in front of the vaporizer 1 and has a tendency to move backward. In the relatively closed space in the horizontal direction surrounded by the front fixing plate 2, the rear fixing plate 5 and the left and right side plates 6, the water mist will move toward the heating chamber 8, making it easier for the second fan 81 to attract it into the heating chamber 8. Compared with a general demisting device, the demisting device provided in this embodiment makes it easier for the second fan 81 to attract the mist in front of the vaporizer 1 through the cooperation of the first fan 3, the second fan 81 and the front fixing plate 2, the rear fixing plate 5 and the side plates 6, thereby improving the working efficiency. Furthermore, when the water mist detector 4 does not detect the formation of water mist, the demisting device stops running to reduce energy consumption, and the side panel 6 moves to open the space so that the staff can access and observe the external conditions of the gasifier 1. When the water mist detector 4 detects the formation of water mist, the side panel 6 moves to enclose the above-mentioned space with the front fixed plate 2 and the rear fixed plate 5.
