Description

Technical Field

[0001] This utility model relates to the technical field of fine water mist generators, specifically a low-pressure fine water mist generator for gas conveying pipelines. Background Technology

[0002] Coalbed methane (CBM), also known as gas, is a type of hydrocarbon gas that adheres to the surface of coal matrix particles or dissolves in coal seam water. It is colorless, odorless, flammable, and explosive, and can easily cause accidents during coal exploration and mining. Methane with a concentration below 30% can be extracted from underground coal seams using a water ring pump and transported to the generator set cylinder through a relatively safe pipeline for power generation. The application of low-concentration methane is of great significance for energy utilization. Low-concentration methane can be transported using pipelines. To prevent explosions during the transport of low-concentration methane, a low-pressure fine water mist generator needs to be installed inside the pipeline.

[0003] Ordinary fine water mist generators lack heating components, which leads to poor environmental adaptability of the device. In cold regions, the water in the unheated fine water mist system may freeze in the pipes, causing nozzle blockage or pipe network rupture, affecting the operation of the device.

[0032] Example 3

[0033] Based on Embodiments 1 and 2, a preferred embodiment of the low-pressure fine water mist generator for gas conveying pipelines provided by this utility model is as follows: Figure 1-5 As shown: The inner wall of the gas conveying pipeline 1 is provided with a drain hole, and a drain pipe 411 is fixedly connected to the inner wall of the drain hole. One end of the drain pipe 411 penetrates the inner wall of the water storage tank and extends to the outside.
