Abstract
The invention provides a sludge scraper for a clarifier, which comprises a bracket, a cylinder body, a flow guide device, a sloping plate, a sludge scraping machine and a reducing motor. The sludge water enters a first-stage flow guide cylinder through a sludge water inlet, is reflected and distributed by a first-stage reflecting plate to enter a second-stage flow guide cylinder and then reflected and distributed by a second-stage reflecting plate, and, by the same way, is distributed by a last-stage reflecting plate to enter the cylinder body. The flow velocity of the sludge water at the sludge water inlet is set to allow the sludge water passing through the last-stage reflecting plate to just reach the farthest edge of the cylinder body, so that the degree of turbulence caused by the incoming water is reduced to the lowest. The sloping plate is arranged inside the cylinder body to allow the upward flow to move up along the surface of the sloping plate, so that on the one hand, the sloping plate serves as an extra flow guide device which can reduce the turbulence problem, and on the other hand, the ash settles down on the surface of the sloping plate, which reduces the settlement distance and shortens the clarification time.
Description
Technical field
The invention belongs to ash water treatment of Coal Chemical Industry gasification furnace and recycle utilization field, the recycling device of particularly a kind of high concentration ash water treatment machine.
Background technology
Coal gasification and then acquisition clean fuel or other elementary chemical products have broad prospects in China, and for reaching the target of energy-saving and emission-reduction, the buck that gasification furnace produces needs recycling.This buck contains solid worry height, particle diameter is little, temperature is high, and concentration of greywater is more than 3%, and particle diameter accounts for more than 70% at 5 μ-90 μ particle, the difficult and circulation of more conventional muddy water.Because medium is in flow regime, and high temperature makes the surface-active collector of medium, bath becomes the turbulent phenomenon of clarifier very serious.And turbulent flow is the key factor that influences clarifying effect, therefore improves the separating effect control turbulent flow of clarifier.Studies show that: the turbulent flow of clarifier mainly is subjected to the influence of factors such as the flowability, device fabrication precision of the form of water distribution and fluidised form, upflow velocity, medium temperature, surrounding air, general letter says that up-flow speed is slow more, water distribution is even more, medium temperature is low more, ambient air is weak more, the device fabrication precision is high more, and turbulent phenomenon is not obvious more.Traditional clarifier is eliminated or the method that weakens turbulent phenomenon mainly is guiding device is set, reduces these two kinds of methods of upflow velocity, but gasification furnace ash water clarifier is if also imitate, and then bath become that the clarifier scale is excessive, overlong time, efficient cross negative consequences such as low.
Summary of the invention
To the objective of the invention is in order addressing the above problem, a kind of effective reduction turbulence level, small scale, the time is short, efficient is high clarifier mud scraper to be provided.
In order to achieve the above object, technical scheme provided by the invention is: a kind of clarifier mud scraper, and it comprises support, cylindrical shell, guiding device, swash plate, mud scraper and reducing motor; Guiding device, swash plate and mud scraper all place in the cylindrical shell; Cylindrical shell is rack-mount; The top of cylindrical shell is provided with grey water inlet; Guiding device is at least two-stage, and guiding device comprises guide shell and reflecting plate; Reflecting plate places the below of guide shell; The one-level guide shell places the below of grey water inlet, and is communicated with grey water inlet; The next stage guide shell is placed in the upper level guide shell and the reflecting plate outside; Swash plate places between the outside and cylinder lateral wall of outermost guide shell; Have the clarified solution outlet on the sidewall of the overhead cylinder of swash plate, mud scraper comprises drive link and scraping arm; Scraping arm places on the bottom surface of cylindrical shell; The center of the below cylindrical shell of scraping arm is provided with the outlet of slag slurry; Reducing motor is installed on the outside of cylindrical shell and is connected with drive link; Drive link and scraping arm are affixed;
The bottom surface of cylindrical shell is that rounding is tapered; The gradient of the gradient of scraping arm and cylindrical shell bottom surface is coincide;
The material of swash plate is an exotic material;
Scraping arm is the steel scraper plate;
The scraping arm below is equipped with rubber slab;
Clarified solution outlet below one week of cylinder inboard wall water leg is installed also;
Also be provided with dredge pump in the outlet of slag slurry;
When the present invention uses, buck enters the one-level guide shell from grey water inlet, reflect water distribution to the secondary guide shell by the first order reflection plate, again by secondary reflex plate reflection water distribution, and the like by afterbody reflecting plate water distribution to cylindrical shell, the grey water flow velocity of ash water inlet just makes the edge that just can arrive cylindrical shell by the buck of last one deck reflecting plate farthest, thereby the turbulence level that water is into caused is reduced to minimum, in cylindrical shell, also be provided with swash plate, upwelling is risen along the swash plate surface, be equivalent to be provided with extra guiding device on the one hand, can alleviate turbulent phenomenon, can make lime-ash be deposited in the swash plate surface on the other hand, reduce the precipitation distance, shorten settling time.Because the cylindrical shell bottom surface is that rounding is tapered, reducing motor drives the mud scraper running, and scraping arm strikes off the lime-ash of cylindrical shell bottom surface, concentrate and collects, and discharges cylindrical shell by dredge pump by the outlet of slag slurry.Clarified solution is discharged cylindrical shell from the clarified solution outlet again from the water leg water leg that overflows into suitable for reading.
