Embodiment Construction

[0025] The following non-limiting examples illustrate the invention.

[0026] refer to figure 1 As shown, the hollow arrow in the figure is the flue gas process, and the solid arrow is the desulfurization wastewater process. The desulfurization wastewater cyclone separation evaporator 6 is composed of a cylinder 61, a cone section 62, a central cylinder 63, an inlet section 64, a bottom slag outlet 65, and a desulfurization wastewater. Waste water nozzle 66 etc. are made up.

[0027] The desulfurization wastewater nozzle 66 is arranged on the wall of the inlet section 64 of the desulfurization wastewater cyclone evaporator 6 , and the desulfurization wastewater 7 is sprayed into the inlet section 64 through the pipeline and the desulfurization wastewater nozzle 66 .

[0028] The inlet section 64 of the desulfurization waste water cyclone separation evaporator 6 is connected to the flue 2 at 200-420°C upstream of the flue gas of the boiler preheater 3, and the suitable connect...

Abstract

The invention discloses a desulfurization wastewater treatment system and belongs to the field of flue gas desulfurization. The desulfurization wastewater treatment system comprises a desulfurization wastewater cyclone separation evaporator, the desulfurization wastewater cyclone separation evaporator comprises a cylinder, a central cylinder, an inlet section, a bottom slag discharging opening and a desulfurization wastewater spray nozzle; a cone section is arranged under the cylinder, the bottom slag discharging opening is formed in the bottom of the cone section, the central cylinder is positioned in the cylinder in a coaxial internal and external embedding form, the inlet section is arranged at the top of the side surface of the cylinder, the desulfurization wastewater spray nozzle is formed in the wall of the inlet section and is communicated with a desulphurization wastewater pipeline, the inlet section of the desulfurization wastewater cyclone separation evaporator is connected with a gas flue of 200-420 DEG C at the upstream of flue gas in a boiler pre-heater, and an outlet of the central cylinder of the desulfurization wastewater cyclone separation evaporator is connected with a gas flue of 80-200 DEG C at the upstream of flue gas in a dust remover. The desulfurization wastewater treatment system disclosed by the invention realizes the desulfurization wastewater zero discharge, simultaneously solves the problem of easy blockage of the gas flues and the dust remover existing in the prior art and has extremely-high equipment reliability and flue gas heat utilization rate.

Description

technical field [0001] The invention belongs to the field of flue gas desulfurization. Background technique [0002] Limestone wet flue gas desulfurization technology is currently the most widely used flue gas desulfurization technique. Using this technology will produce a certain amount of wastewater. The wastewater contains high concentrations of heavy metals and suspended solids, and is weakly acidic. Direct discharge will harm the environment. If it causes harm, it must be treated and discharged after reaching the standard. The existing limestone wet flue gas desulfurization wastewater treatment mainly adopts the chemical dosing treatment process, which is complex, with many equipments, high failure rate, and large site occupation. higher. [0003] With the implementation of zero discharge of desulfurization waste liquid in coal-fired power plants in my country, some new technologies have emerged, such as Chinese patent document application number CN200910185023.3 and ...
