Background technology
In wet method fume desulfurizing system, along with the passing of running time, chlorine ion concentration can constantly rise, and heavy metal also can enrichment, thus relevant device in corrosion desulphurization system affect gypsum qualitt.Be not corroded to protect desulphurization system and reduce the content of beary metal in gypsum, Waste Water Treatment must be entered by a certain amount of desulfurization wastewater of periodic exhaustion, the chlorion in desulphurization system and heavy metal concentration are maintained in tolerance interval.The Waste Water Treatment waste water supply technique that this field is traditional is at present as follows: gypsum slurries access gypsum rotational flow station, whole filtrates that the major part of gypsum eddy flow overflow and underflow produce after vacuum belt machine all enter reuse water tank, return desulphurization system reuse, the overflow of sub-fraction gypsum rotational flow station is had to be access in waste-water vortex station service tank, deliver to waste-water vortex station by waste-water vortex station supply pump and carry out cyclonic separation again, waste-water vortex station underflow enters reuse water tank, return desulphurization system reuse, overflow enters storage of waste water case, supply Waste Water Treatment.This technological problems is: overflow solid content in waste-water vortex station is about 3.0%, and a large amount of gypsum is brought into Waste Water Treatment, can increase the solid loading of Waste Water Treatment, increasing device capacity requirement, increases investment cost; For reaching treatment effect, a large amount of medicament need be added, improve operating cost; Meanwhile, containing heavy metal and medicament in the gypsum patty will produced after Waste Water Treatment agent-feeding treatment, can not comprehensive reutilization be carried out, can only landfill be transported outward, solid waste amount be increased, causes the wasting of resources.
Summary of the invention
In order to the problem that the waste water solid content overcoming Waste Water Treatment supply is high, the present invention proposes a kind of Waste Water Treatment waste water supply technique for wet process of FGD field.This technology utilization vacuum belt dewaterer one-level filtrate, as the source water of Waste Water Treatment, reduces the solid loading of Waste Water Treatment, reduces system investments and operating cost, reduces the generation of solid waste.Concrete technical scheme is:
A kind of wet flue gas desulfurization waste water treatment system waste water supply system, by gypsum rotational flow station, vacuum belt dewaterer, one-level filtrate receiving magazine, secondary filtrate receiving magazine, storage of waste water case, waste water delivery pump, vavuum pump forms, gypsum slurries enters the charging aperture of gypsum rotational flow station, the overfall of gypsum rotational flow station is connected with the top of reuse water tank, the underflow of gypsum rotational flow station is connected with the charging aperture of vacuum belt dewaterer, the filtrate pipe of vacuum belt dewaterer is divided into two parts by vacuum insulation panel, be connected with the first half of one-level filtrate receiving magazine with secondary filtrate receiving magazine respectively, the bottom of one-level filtrate receiving magazine is connected with the Lower Half of storage of waste water case, the entrance of waste water delivery pump is connected with the Lower Half of storage of waste water case, waste water conveying delivery side of pump is connected with Waste Water Treatment, the bottom of secondary filtrate receiving magazine is connected with the Lower Half of reuse water tank, the slurries of reuse water tank return desulphurization system reuse.
Utilize above-mentioned wet flue gas desulfurization waste water treatment system waste water supply system to supply a method for waste water, comprise the steps:
A. gypsum rotational flow station (2) overflow slurry is all accessed reuse water tank (10), return desulphurization system reuse;
B. the filtrate pipe of vacuum belt dewaterer (3) is divided into two sections by vacuum insulation panel (9), one-level filtrate filtrate being divided into dilute without gypsum patty will flushing water (11) and the secondary filtrate two parts diluted through gypsum patty will flushing water (11);
C. by one-level filtrate access storage of waste water case (6), be then transported to desulfurization wastewater treatment system by waste water delivery pump (7) and process.
The present invention is by the improvement of wet flue gas desulfurization waste water treatment system waste water supply technique, eliminate the setting of waste-water vortex station, waste-water vortex station service tank and pump, decrease the capacity of Waste Water Treatment and the dosage of medicament simultaneously, reduce investment and operating cost.In addition, enter the reduction of waste water solid content in Waste Water Treatment, the generation of solid waste can be reduced, avoid the wasting of resources.
