March 5 , the Guangdong Environmental Protection Equipment Co., Ltd. Xiang Chun , announced by the company’s cooperation with Guangdong Development Co., Ltd. Hui-yun dioxide and dry chemical sludge press , has been cast in the utilization of the benefits of cloud Titanium titanium workshop continuous operation over six months, the single production day moisture 15% to 25 % titanium gypsum 180 t dry material . Titanium dioxide production of sulfuric acid has long plagued the biggest problem – Ti Gypsum pollution solved, sulfuric acid titanium dioxide production is expected to move towards a comprehensive clean . Industry experts believe that this is currently the world’s best dry pressed , the lowest operating costs of sludge treatment equipment , its technical level far beyond Germany and Japan and other countries of similar products.
Hui-Yun Titanium operation results show that the application of the device , without the traditional high-energy drying device , you can put a solid content of 20 % or less of calcium sulfate slurry , once pressed dry to a moisture content below 20% solid content of 80% or more solid plaster . Each operating cycle is only 12 minutes a day can produce 180 tons of dry plaster . Sludge drying costs declined more than 70% , only 21 % of the traditional drying techniques applied pressure filtration equipment , energy consumption is only 15% of traditional equipment .
Xiang Jun technical director , said Wang Jun , the device can replace titanium dioxide production enterprises existing membrane filter press system, not only solved the use of titanium dioxide titanium gypsum has long plagued this problem , but also for enterprises to increase economic efficiency. The device can effectively solve the titanium gypsum sludge contamination of groundwater , saving landfill space for the whole industry was around 8500 acres, conservation of natural gypsum cement with mineral resources of 500 million tons , such as drying can save the use of titanium gypsum drying coal consumption about 200 million tons, while saving the titanium gypsum transport , landfill costs, so the industry can save about $ 500 million a year.
According to Wang Jun introduction , the device working pressure , good pressure dry effect , the normal working pressure of 100 kg ( equivalent to 10MPa), the maximum working pressure of up to 200 kg , can be a variety of sludge thousands of hard- pressed dry bulk materials. This sludge dry bread soaked in water for a few days would no longer be reduced to scattered dissolved sludge drying may, without directly crushed into powder harmless disposal and resource utilization , grinding process does not bear cake , do not dust. Inorganic sludge can be pressed to 85% dryness , organic sludge can not be quenched pressed dry to 50% dryness , after quenching can be pressed to 80% dryness . Meanwhile, the processing capability , low processing cost. The largest single machine can handle thick slurry sludge reached 2,000 cubic meters / day, the entire line day operating costs of about 2,500 yuan (including consumables , electricity , labor costs ) , according to the output of dry mud meter costs 10 to 40 yuan / ton. In addition , long machine life, good anti- corrosion properties , the environment can be used in the mud more than 10 years ; high degree of automation , pure physical crushing , the process is not heated , no consumption of steam , without medicine, without secondary pollution , press out the water may be vertical or reuse .
Gypsum is a product of titanium after high water sulfate process titanium dioxide waste water treatment , as amended by the existing water pressure filtration pressure filtration equipment was still as high as 45 % -60 % , a variety of chemical composition fluctuation is large, although that can be used in the cement industry , but its high moisture content and low content of calcium sulfate , few companies are willing to use. At present, the total amount of titanium dioxide industry annual 20 million tons of sludge , a large pile of waste gypsum nowhere . Existing filter dewatering equipment generally does not exceed the working pressure
Over 16 kg , moisture content of the sludge produced are high and there was mashed , difficult to transport and post-processing . Some Decanters and air dry the filter combined with titanium gypsum moisture content of 30% can be achieved , but the high energy consumption, and the material was mud powder, not dry , easy to absorb moisture , not water .
It is reported that the device has been patented(http://www.lubonchem.com supply)
