Abstract

The invention discloses a shale gas fracturing flow-back fluid electrolysis disinfection device skid and relates to the technical field of environment protection water treatment. The gas fracturing flow-back fluid electrolysis disinfection device skid comprises a water preprocessing skid, an electrolysis skid and an electrolysis product processing skid and is characterized in that the electrolysisskid comprises a sodium hypochlorite generator, the feed inlet of the sodium hypochlorite generator is provided with a feed pipeline, the feed pipeline is communicated with a soft water tank and a sodium chloride storage tank through pipelines, a first water distribution pump for conveying soft water is arranged on the pipeline between the feed pipeline and the soft water tank, and a second waterdistribution pump for conveying salt water is arranged on the pipeline between the feed pipeline and the sodium chloride storage tank; the electrolysis product processing skid comprises a sodium hypochlorite storage tank and an exhaust unit for discharging hydrogen, and a feeding pipe with a feeding pump is connected to the discharge outlet of the sodium hypochlorite storage tank. The device skidis convenient to demount, capable of achieving whole vehicle haulage, small in floor space, convenient and flexible in setting and applicable to different areas.

Description

technical field [0001] The invention relates to the technical field of environmental protection water treatment, and more specifically relates to a shale gas fracturing flowback liquid electrolytic sterilization device skid. Background technique [0002] Fracturing is a major measure to increase the production of unconventional oil and gas resources such as shale oil and gas. It uses fracturing trains to inject fracturing fluid into the formation at high pressure and form fractures, thereby significantly improving the conductivity of the formation and making oil and gas resources more efficient. Smooth output, to achieve the purpose of increasing production. [0003] A large number of chemicals are added to the fracturing fluid, including water treatment agents such as thickeners, gel breakers, crosslinking agents, drainage aids, and buffers. After reacting with the formation, the liquid that is discharged to the ground is called fracturing Crack back fluid. It has the cha...
