Technical field
It the utility model is related to a kind of mud scraper for flue gas desulphurization system outer loop regenerated liquid sedimentation basin.
Background technology
Smoke-gas wet desulfurization is generally inhaled using insoluble alkaline matters such as lime, magnesia as desulfurizing agent, sulfur dioxide
Receipts process uses serum recycle system, and the sulfur dioxide that its sweetening process includes the gas-liquid mass transfer of absorbing liquid and flue gas absorbs instead
Should, the sulfite oxidation of desulfurization generation is each to circulate into the oxidation reaction of sulfate, the neutralization reaction of absorbing liquid and desulfurizing agent
The absorbing liquid of process whole undergoes above three reaction, pH value in reaction, reaction time, the reaction temperature of often step reaction needs
The conditions such as degree are different.With the development of desulfurization technology, more and more sulfur removal technologies use absorption/oxidation and doctor solution again
The technology of raw phase separation, makes every step reaction to carry out in optimal conditions, desulfurization product master after the reaction of desulfurization regeneration of absorption solution
It to be calcium sulfite/calcium sulfate/magnesium sulfite (crystalline solid) etc..This partial desulfurization product needs to discharge from desulfurization cycle system,
Conventional method is filtered again by vacuum belt machine using after cyclone concentration, and this method energy consumption is big, and equipment corrosion abrasion is tight
Weight.And most economical method is after being concentrated using sedimentation basin to the solid-state desulfurization product in regenerated liquid, to greatly reduce treating capacity,
Sludge drying is carried out by filter press again.
The sewage of many industrial wastewaters or other field is required for removing the purified treatment of solid mixt, most commonly used
It is radical sedimentation basin, mud scraper is that the key equipment that sludge flow/is arranged outside is promoted in radical sedimentation basin.It is existing commonly to scrape
The working method of mud machine is to drive main axis using the driving device of center driving or peripheral-traction, and scraping arm turns with main shaft
Dynamic to shift sludge onto pond center collection mud pit, sludge is automatically drained out outside pond under hydrostatic pressure.But in desulfurization industry due to desulfurization
Product (calcium sulfite/calcium sulfate/magnesium sulfite) is than great, poor fluidity, and bridging, hardened, fouling easily occurs in desulfurization sludge
Phenomena such as, desulfurization sludge is easily deposited in collection mud pit, and sludge hardening, fouling cause the blocking of mud discharging mouth, collect the desulfurization in mud pit without
The unobstructed outer row of method.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of mud scraper for the flue gas desulphurization system for lifting spoil disposal efficiency.
The technical scheme for implementing the utility model is as follows：
A kind of mud scraper for flue gas desulphurization system, including service bridge, the main shaft being arranged vertically on below service bridge are main
The upper end of axis is rotatably dispose on service bridge, and is assemblied on service bridge and is driven main shaft to be filled around the driving of own rotation
Put, at least provided with two in the scraping arms of arrangement of being inclined upwardly on main shaft, below each scraping arm being at least equipped with two scrapes
Plate, forms angle arrangement between the scraper plate and scraping arm；
The servo axis for following main axis are connected with by shaft coupling in the lower end of main shaft, stirring is equipped with servo axis
Paddle, forms angle arrangement between the stirring sheet and servo axis in the agitating paddle；
The angle of inclination of scraper plate is opposite with the angle of inclination of agitating vane.
Further, the scraper plate is presented down with agitating vane is arranged vertically.
Further, 30 ° -45 ° of angle is formed between the scraper plate and scraping arm.
Further, 15 ° -30 ° of angle is formed between the stirring sheet in the agitating paddle and servo axis.
Further, the driving device drives main shaft to be rotated between 0.4-1.2rad/s.
Above-mentioned technical proposal is employed, the invention has the advantages that：Can by the angle formed between scraper plate and scraping arm
To tackle high load capacity desulfurizer, in the collection mud pit that sedimentation basin base sludge is pushed to the sedimentation basin center of circle, place of the scraper plate to sludge
Reason efficiency is obviously improved；Due to agitating paddle and the inclination angle in collection mud pit on the contrary, and the stirring sheet of agitating paddle with
Moving axis (main shaft with servo axis be total to axial line) can ensure desulfurization sludge in collection mud pit not hardened, fouling in angle arrangement
There is an extrapolability to mud discharging mouth at the same time, prevent the blocking of mud discharging mouth.In addition, mud is scraped in driving device drive in the utility model
The angular speed of machine is controlled between 0.4-1.2rad/s, its swing circle is much smaller than the mud scraper of conventional radical sedimentation basin, makes
Desulfurization product will not be compacted in a swing circle, is hardened.The mud scraper of the utility model is simple in structure, is not easy to take
Phenomena such as bridge, hardened, fouling and caused by blockage problem, lift spoil disposal efficiency；Meanwhile the few low cost of equipment construction, less energy consumption.
