Problems solved by technology

Although some achievements have been made in the treatment of saline wastewater, when the evaporation equipment is in use, after the high-salt wastewater is heated and gasified, it is easy to form crystals on the surface of the heat exchange tube, which leads to fouling and affects the thermal conductivity of the heat exchange tube. , thereby reducing the evaporation efficiency. In addition, the heat exchange process between the water vapor and the heat exchange tube will also form scale on the inner wall of the heat exchange tube, thereby reducing the heat exchange efficiency.

Abstract

The invention discloses high-salinity wastewater treatment equipment and a sewage treatment method. The high-salinity wastewater treatment equipment comprises a plurality of heat exchange pipe units arranged in a shell, wherein a steam inlet and a steam outlet are formed in the shell, a spraying pipe is arranged in the top of the shell, a movable supporting mechanism is movably arranged in the shell, a containing cavity is formed in the side wall of the shell, a rotary driving mechanism is arranged in the containing cavity, the outer wall of the heat exchange pipe is sleeved with an external cleaning mechanism, a first driving mechanism is arranged in the shell, a shifting mechanism is arranged on the first driving mechanism, an internal cleaning mechanism is arranged in the heat exchange pipe, a second driving mechanism is arranged in the heat exchange pipe, and a linkage mechanism is arranged at one end of the shell. The equipment is simple in structure, and can effectively remove crystals on the surface of the heat exchange pipe and scales on the inner wall of the heat exchange pipe, so that the heat exchange efficiency of the heat exchange pipe is effectively guaranteed, and the evaporation efficiency of high-salinity wastewater is improved.

Description

technical field [0001] The invention relates to high-salt wastewater treatment equipment, and also relates to a sewage treatment method based on the high-salt wastewater treatment equipment. Background technique [0002] With the rapid development of my country's industry, more and more high-salt wastewater is produced in the daily production of petroleum, chemical, metallurgical and electric power industries. In many places such as the coal chemical industrial park in the north, in order to accommodate this type People have built evaporation ponds for temporary storage of wastewater, but as time goes by, many evaporation ponds have become overcrowded and cannot continue to accept new high-content salt water. At present, the treatment of saline wastewater is mainly based on evaporation and membrane treatment technologies. Evaporation technologies such as multi-effect evaporation MED, multi-stage flash evaporation MSF, vapor compression condensation VC, and mechanical compress...
