Embodiment Construction

[0044] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0045] The sludge rapid dehydration and solidification system in the present invention collects the original mud, adds preset amounts of solidifying agent and dehydrating agent to a continuous pipeline, and outputs them after mixing. The whole dehydration and solidification process is realized continuously.

[0046] see figure 1 As shown, it is a schematic diagram of the overall structure of the sludge rapid dehydration solidification system of the present invention, the system includes a slurry pump 1, a coagulant mixing device 3, a dehydrating agent mixing device 6, a control device and a pipeline 5 , wherein, the slurry extraction mud pump 1 is used to extract natural mud, the flow rate of the first mud pump 1 is determined according to the performance of the overall equipment, and it is input into the ...

Abstract

The invention relates to a rapid dewatering and curing method for sludge. The method is as below: slurry sucked by a slurry pump is output to a pipeline, has flow rate measured, and flows into a coagulant mixing device, and the measurement results are sent to a control device; the control device, according to the preset coagulant addition rate, determines the rotation speed of a screw conveying unit of the coagulant mixing device, and adds the coagulant to the coagulant mixing device according to the speed of the rotation speed; a second flow measuring element and a concentration measuring element measure the flow rate and concentration of slurry in the pipeline; the control device based on the measured flow rate and concentration data adds the coagulant and clean water into a three-box overflow type stirring box for stirring according to preset dewatering agent concentration; and the dewatering agent mixing device is output according to the preset dewatering agent addition amount, and mixed with slurry in the mixing device on the pipeline. According to the invention, the sludge is treated with coagulant and dewatering agent, so as to output to slurry met the requirements.

Description

technical field [0001] The invention relates to a sludge dehydration and solidification method, in particular to a rapid dehydration and solidification method by adding a coagulant and a dehydrating agent. Background technique [0002] The existing dehydration system can realize the dehydration and solidification of sludge. A certain amount of curing agent is added to the collected slurry. A construction process and device for land reclamation by dredging and filling sludge. The device includes solidification treatment system A and paving of improved slurry System B. This A includes: pumping, debris screening, curing agent storage, curing agent delivery, compressed air delivery and mixed mud mixing delivery and other devices. This B includes: connecting pipe sections, hoses or belt conveyors and carrying and moving devices. The construction process is as follows: ① Fill the sludge into the filling area or the sedimentation tank, and form a thick sludge accumulation layer a...
