Description

Water treatment device and condensate fine treatment system Technical Field The application relates to the technical field of water supply treatment, in particular to a water treatment device and a condensate water fine treatment system. Background At present, the pollutants in the condensate water of the thermal power plant are mainly corrosion products of iron and a small amount of salt, and the corrosion products of iron are the biggest potential safety hazard of a water vapor system. The thermodynamic system accidents caused by corrosion occur every year, and serious safety accidents can be caused. Rust can be bred in a large number during unit maintenance or non-stop period, a large amount of waste water is required to be discharged during starting, a large amount of heat energy and water resource are wasted, and meanwhile the unit operation time can be influenced. During normal operation of the system, iron is not removed thoroughly by water treatment equipment and technology, residual ferric oxide in condensed water can accelerate corrosion of the system, and meanwhile, equipment blocking phenomena such as a drain valve and the like can be caused by accumulation in a pressure drop zone. In the related art, the water passing through the treatment is discharged from the water outlet pipe, and when the subsequent backwash water flushing operation is performed, an external water source is required to be injected into the barrel, so that water resource waste is easily caused. And when the backwash water flushing operation is finished, the iron-containing impurities and the flushing water are doped and discharged, and the iron-containing impurities and the flushing water are required to be separated manually, so that the labor burden of staff is increased.

And the separation assembly can collect impurities in backwash water discharged from the backwash water outlet pipeline so as to realize separation of iron-containing impurities and backwash water, and reduce labor burden of workers. In the water treatment process, the moving mechanism drives the permanent magnet bar assembly to move downwards along the axial direction of the cylinder until the magnet bar is completely inserted into the fixed pipe assembly to form a closed magnetic circuit. The water to be treated enters the cylinder from the water inlet pipeline and passes through the gap of the fixed pipe assembly from top to bottom so as to be magnetized and flocculated. The magnetic field in the inner wall of the fixed pipe component adsorbs ferromagnetic impurities (such as Fe 3O4 particles) in water, the impurities are attached to the surface of the fixed pipe component, qualified water after flocculation adsorption treatment flows into the circulating water recei
