Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, in particular to a chimney with a demisting function. Background Technique

[0002] The vaporizers of liquefied natural gas receiving stations mainly adopt open rack vaporizers (ORV), intermediate fluid vaporizers (IFV) and submerged combustion vaporizers (SCV). Among them, the submerged combustion vaporizer belongs to the fuel heating type vaporizer, which uses the flue gas generated by fuel combustion as the heat source. Since the flue gas is in direct contact with water, it stirs the water violently while heating the water. The hot water then exchanges heat with the LNG (liquefied natural gas) in the heat exchanger tube, greatly improving the heat transfer efficiency. The flue gas generated by the submerged combustion vaporizer will be discharged through the chimney. Since there are a lot of water mists inside the flue gas, a wire mesh demister is needed to reduce the water content in the flue gas to achieve the demisting function of the flue gas. However, most wire mesh demisters are directly placed in the chimney, and it is necessary for workers to enter the chimney to replace the wire mesh demister, which is too troublesome during replacement. At the same time, there are a lot of toxic gases in the discharged flue gas, which will pollute the air and affect the physical health of the human body. Content of the Utility Model

[0003] The purpose of the utility model is to provide a chimney with a demisting function to solve the problems that the wire mesh demister is too troublesome to replace and there are a lot of toxic gases in the discharged flue gas, which will pollute the air and affect the physical health of the human body in the background technique.

The screw 313 is screwed, and the screw 313 passes through the threaded hole 312 and is threadedly connected to the chimney body 2, so that the connecting sleeve 305 is fixed to the chimney body 2. When the wire mesh demister 309 needs to be replaced, the screw 313 is unscrewed, and the connecting sleeve 305 is pulled out of the chimney body 2 through the handle 311, and then the wire mesh demister 309 is pulled out of the connecting sleeve 305 through the handle 310 and the fixing block 308, thereby facilitating the replacement of the new wire mesh demister 309. When the inside of the chimney body 2 needs to be repaired, the bolt 504 is unscrewed, the fixing bracket 503 is opened, the maintenance personnel climb to the top of the chimney body 2 through the ladder 7, and then enter the inside of the chimney body 2 through the connecting groove 501 for maintenance. When the flue gas passes through the wire mesh demister 309, the wire mesh demister 309 can reduce the water content in the flue gas. Through the wire pad of the demister, the entrained mist can be removed to achieve the demisting function of the flue gas. When some flue gas passes through the filter plate 4, the filter plate 4 is mainly made of activated carbon particles and has good adsorption performance. Especially for toxic and harmful gases such as odor, abnormal smell, benzene, xylene, formaldehyde, and methanol, it can filter the toxic and harmful gases in the flue gas well.
