Abstract
The utility model relates to a full-automatic coal ash water speed change processor, which belongs to water treating equipment. The utility model comprises a PLC full-automatic control device and a box body, wherein the box body is composed of a mixed reaction zone, a settling zone and a filtering back-flushing zone, which are orderly communicated with each other by water; the upper part of the mixed reaction zone is provided with a water inlet, the upper part of the filtering back-flushing zone is provided with a water outlet, the bottom of each zone is provided with a mud discharging port, the mixed reaction zone is divided into a plurality of small reaction zones by baffles and each baffle is provided with outlets the caliber sizes of which are different. Cast reagents and wastewater are thoroughly mixed to react under the hydraulic condition after speed changes for many times. The utility model has the advantages of advanced structure and high performance, and is mainly used for the treatment which needs much industrial water consumption and contains a large quantity of solid suspended substances, such as electric power, mines, coal mines, metallurgy, architecture, etc. The utility model realizes closed circuit circulation of industrial water, has the function of recycling rare raw materials, and is especially suitable for treatment and recycling of wastewater for flushing coal bands in large and medium-sized power plants.
Description
Technical field
The utility model belongs to water treating equipment, refers in particular to a kind of full-automatic coal buck variable-speed processing device, is specially adapted to processing, the reuse of big-and-middle-sized power plant coal transportation belt flushing waste water.
Background technology
Power plant's coal transportation belt flushing waste water water yield is big, contains a large amount of shape suspended substances admittedly, adopts many complete equipments such as coal ash water cyclone, coal ash water separator and pressure filter to finish usually, and intermediate water tank and middle water pump need be set.Facility investment expense height, working cost is big, floor space is big, efficient is low, maintenance capacity is big.The coal ash water cyclone is by the suspended substance of eddy flow centrifugation, a precipitation part, handles through the coal ash water separator again, and it has parts such as mixing and reaction chamber, separate chamber, inclined tube negative area, filtrating area to constitute.Round structure is circumscribed to be influenced because it is subjected to, and hybrid reaction time, inclined tube settling time, filtration area, filtering layer height, backwash water etc. all are subjected to certain limitation.
Summary of the invention
The utility model is just for overcoming above deficiency, a kind of structure advanced person is provided, well behaved full-automatic coal buck variable-speed processing device, main innovate point is that the hybrid reaction district is made of several differential responses sub-districts, be equipped with the different outlet of caliber size on each different reaction sub-district partition plate, making liquid produce the speed change reaction by big small-bore variation mixes, specifically implement like this: full-automatic coal buck variable-speed processing device, comprise the PLC device for automatically controlling, the hybrid reaction district that casing is communicated with by water successively, the negative area, filtering the back flushing district forms, top, hybrid reaction district is equipped with water-in, filter top, back flushing district and be equipped with water outlet, each bottom, district is equipped with mud discharging mouth, it is characterized in that the hybrid reaction district is divided into several reaction sub-districts by partition plate, is equipped with big small-bore different outlet on the partition plate.The outlet that varies in size by bore on each different reaction sub-district partition plate in the speed change hybrid reaction district produces the speed change reaction and mixes, and through speed change repeatedly, along with the change of flow rate of water flow, makes the medicament and the reaction of sewage thorough mixing that add under hydraulics.
Negative area of the present utility model is made up of floor disengaging zone and mud-water separation district, meet the hybrid reaction district before the floor disengaging zone, take over filter back flushing district behind the mud-water separation district, described mud-water separation district overflow section is greater than floor disengaging zone, and each district is built-in with that inlet flume, middle part are equipped with the inclined tube filler, top is provided with water leg.The floor disengaging zone that enters the negative area behind the sewage process speed change reaction zone flows into the mud-water separation district again, because floor disengaging zone and mud-water separation district overflow section is different, the upflow velocity in two districts is also different, thereby the shale that the speed change sedimentation is different, some easy sedimentary decorating films of layer disengaging zone sedimentation, the less shale of some difficult sedimentary particles of mud-water separation district sedimentation, this district's particular structure has improved spoil disposal concentration, prolong sludge discharging period, save the spoil disposal water consumption.
The utility model adopts two lattice to filter, and two lattice move simultaneously, and when a lattice backwash, another lattice continue to filter; Pump suction type is adopted in backwash, and backwashing pump is built in the filtrate top that pump filters the back flushing district.
The control of PLC full-automatic intelligent is all adopted in the operation in each district of the utility model, and interlockings such as each power-equipment in the equipment and under meter, ultrasonic liquid leveller, turbidimeter, differential pressure pilot, time make the operation of equipment be in the full-automatic intelligent state.
The outlet that this equipment varies in size by bore on each partition plate of hybrid reaction sub-district, under hydraulics through speed change repeatedly, make the medicament and the reaction of sewage thorough mixing that add, structure design by the negative area again, improved spoil disposal concentration, prolonged sludge discharging period, saved the spoil disposal water consumption, the device structure advanced person, functional, be mainly used in electric power, the mine, the colliery, metallurgical, industrial water consumptions such as building are big, contain a large amount of processing of shape suspended substance admittedly, realize the process water closed cycle, and play a part to reclaim precious raw material, be specially adapted to the processing of big-and-middle-sized power plant coal transportation belt flushing waste water, reuse.
