Abstract

The invention provides a shale gas flowback sewage treatment system, which consists of an electrochemical cell, a heat exchanger, a steam compressor, an evaporator and an engine. A liquid outflow end bronze drum pipeline of the electrochemical cell is communicated with a cold fluid inlet of the heat exchanger, a cold fluid outlet of the heat exchanger is connected to the steam compressor through a pipeline, the steam compressor is also in connection with the evaporator through a pipeline, a steam outlet of the evaporator is connected to a hot fluid inlet of the heat exchanger through a thermal insulation pipeline, the engine is connected to a power supply end of the steam compressor, the pipeline between the electrochemical cell and the heat exchanger and the pipeline between the steam compressor and the evaporator are both equipped with filter screens. The system provided by the invention solves the problems of incomplete sewage treatment, high cost, secondary pollution to water source, energy waste and the like in existing methods, and the invention belongs to the technical field of shale gas development.

Description

Technical field [0001] The invention provides a shale gas flowback sewage filter device, which belongs to the technical field of shale gas development. Background technique [0002] The current shale gas development technology mainly adopts hydraulic fracturing. The hydraulic fracturing method is to inject a mixture of some chemicals, water and sediment into an underground well through high pressure, fracturing the nearby shale reservoir structure, and adsorbing and The free shale gas creates pores and fissure channels, which is conducive to the collection of shale gas. The reservoirs of shale gas reservoirs are generally characterized by low porosity and low permeability. The airflow resistance is greater than that of conventional natural gas. The horizontal well drilling and hydraulic fracturing techniques necessary for shale gas development consume huge amounts of water, and the fracturing is completed. Afterwards, the fracturing fluid must be flowbacked. The COD content in t...
