Power plant wastewater chloride ion removal device

Abstract

The invention relates to a power plant wastewater chloride ion removal device. The device comprises a kettle body and a kettle cover fixedly mounted above the kettle body, and an adjustable stirring mechanism is mounted on the kettle cover; the adjustable stirring mechanism sequentially comprises a lifting device, a driving device and a stirring device from top to bottom; and a driving motor in the lifting device drives a stirring rod in the stirring device to translate and rotate through a driving device, so that the stirring area and range are increased, the mixing effect of extract liquor and wastewater is improved, and the chloride ion extraction and removal effect is improved. According to the present invention, by arranging the plurality of the inclined rods, the area and the range are increased, and the number of the inclined rods is set, such that the effect equivalent to the omnibearing stirring can be almost achieved during the operation so as to significantly improve the mixing effect of an extraction liquid and the wastewater.

Description

technical field [0001] The invention relates to the technical field of waste water chloride ion treatment equipment, in particular to a power plant waste water chloride ion removal device. Background technique [0002] The high-chlorine wastewater of thermal power plants mainly includes resin regeneration acid, alkali wastewater and desulfurization wastewater. The most commonly used method is to use high-chloride wastewater for ash storage mixing and coal yard spraying, but it will affect the quality of ash reuse and the quality of coal. Sprinkler operation of field and coal handling system. In fact, this reuse method does not fundamentally solve the problem of reuse of high-salt wastewater, but only transfers it to other systems, and the concentration of chloride ions in chlorine-containing wastewater in power plants is constantly changing. Choosing the corresponding treatment for the concentration of chloride ions in wastewater will only result in an increase in treatment...

[0002] The high-chlorine wastewater of thermal power plants mainly includes resin regeneration acid, alkali wastewater and desulfurization wastewater. The most commonly used method is to use high-chloride wastewater for ash storage mixing and coal yard spraying, but it will affect the quality of ash reuse and the quality of coal. Sprinkler operation of field and coal handling system

In fact, this reuse method does not fundamentally solve the problem of reuse of high-salt wastewater, but only transfers it to other systems, and the concentration of chloride ions in chlorine-containing wastewater in power plants is constantly changing. Choosing the corresponding treatment for the concentration of chloride ions in the wastewater will only increase the treatment cost

[0003] Existing a kind of device that adopts circulation extraction to remove chlorine ion, as disclosed in the Chinese invention patent publication number CN207031017U a kind of removal device of chlorine ion in chlorine-containing waste water, comprises infusion pump, stirring pool, water distribution pool, static A separation pool, an extraction liquid collection pool and a waste water collection pool are installed; the inside of the waste water collection pool is provided with a chloride ion concentration monitor, and the outer wall of the waste water collection pool is provided with a waste water discharge port and a waste water return port, and the waste water discharge port is provided with a first Solenoid valve, a second solenoid valve is provided at the waste water return port, and the waste water return port communicates with the liquid injection pump through the waste water return pipe; the extract liquid discharge port is provided on the outer wall of the extraction liquid collection tank; the chlorine-containing waste water provided by this patent The removal device of chlorine ions can realize the repeated extraction and removal of chloride ions in chlorine-containing wastewater; but the removal device of chloride ions in this chlorine-containing wastewater also has the following deficiencies: the function of the agitator is single, and its stirring range Fixed, so the stirring area and range are limited, and the stirring range cannot be adjusted according to the demand, which greatly affects the mixing effect of the extract, thereby reducing the effect of chloride ion extraction and removal
