Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a shale gas well sewage rapid evaporation treatment device. Background Art

[0002] Hydraulic fracturing technology is usually used in the process of shale gas well exploration. Water, gravel and chemical additives are injected into underground high-pressure shale layers to create cracks and release natural gas. Most of the water used in the process will return to the ground, which is called "return water" or "fracking return water". Since the water contains natural substances in the rocks and chemicals added during the fracturing process, sewage will be formed. In order to avoid the impact of sewage on the environment, evaporation treatment equipment is required to treat the generated sewage.

[0003] However, during the use of the existing evaporation treatment device, due to the low heating rate, it takes a long time to heat the fracturing return water, which leads to a slow evaporation rate of the fracturing return water, thereby reducing the treatment efficiency of the fracturing return water.
