Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. While the invention will be described in conjunction with the preferred embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.
[0013] like figure 1 As shown, this desulfurization wastewater sludge treatment device includes a clarifier 1, a sludge pump 2, a slurry discharge port 3 and a vacuum belt conveyor 4; the lower end pipe of the clarifier 1 is connected to the slurry discharge port 3 through a sludge pump 2 , the slurry discharge port 3 is connected to the vacuum belt conveyor 4; the desulfurization absorption tower slurry is pumped to the gypsum cyclone station 5 through the gypsum discharge, and the gypsum slurry...

The invention discloses a desulphurization wastewater sludge treatment device. The desulphurization wastewater sludge treatment device comprises a clarifier, a sludge pump, a slurry blanking hole and a vacuum belt conveyor, wherein a pipeline at the lower end of the clarifier is connected to the slurry blanking hole, and the slurry blanking hole is connected to the vacuum belt conveyor; slurry in a desulphurization absorption tower is fed to a gypsum hydrocyclone station by virtue of a gypsum discharging pump, and a gypsum slurry blanking hole of the gypsum hydrocyclone station is connected to the vacuum belt conveyor; and the slurry blanking hole is arranged at the rear end of the gypsum slurry blanking hole. The desulphurization wastewater sludge treatment device has the beneficial effects that after bottom sludge passes through a vacuum belt dehydrating system, a byproduct gypsum is generated, recycling of the bottom sludge is realized, and the discharge problem is solved; energy consumption is low, and stability is good; investment and cost for operation and maintenance are low, and floor area is zero; and compared with the original system, filter press equipment and an auxiliary system thereof are eliminated, a mechanical uniform distribution device (containing no running motor) is added, and a sludge delivery pipeline is changed while energy consumption is almost not increased; besides, investment cost is low, maintenance is simple, and floor area is small.
Description
technical field [0001] The invention belongs to a waste water sludge treatment device, and more specifically relates to a desulfurization waste water sludge treatment device. Background technique [0002] At present, the desulfurization system of coal-fired power plants treats wastewater: the wastewater enters the clarifier after neutralization, sedimentation, and flocculation. . When the sludge accumulates to a certain height, start the sludge conveying pump to feed the filter press to carry out the sludge filter press operation. The mud cake after pressure filtration is transported by car for disposal, and the filtrate is sent back to the desulfurization wastewater storage tank for further processing. This treatment method has the problem of sludge discharge, and the related treatment costs are high. At the same time, the failure rate of the filter press affects the stability of the system operation. Contents of the invention [0003] The purpose of the present invent...
