The utility model discloses a novel on-line filter for coal water slurry. It is characterized in that it has a filter cartridge, connected to a connecting section on the upper side, connected to a return flow chamber on the lower side, and has a sleeve on the outside. The lower end of the return chamber is connected with the sewage pipe and the coal-water slurry return pipe. The connecting section is provided with a coal-water slurry inlet pipe and a forward cleaning pipe for the filter. The lower end of the sleeve is provided with a coal-water slurry outlet pipe and a reverse cleaning pipe for the filter. The filter cartridge A cleaning brush and a scraper are arranged inside (outside), and the cleaning brush is connected with the shaft through a bolt or a spring and the scraper through an adjusting bolt, and is driven by a low-speed motor. The utility model has the advantages of simple and compact structure, small volume, convenient maintenance and replacement, and safe and reliable operation.
Description
The utility model belongs to high viscosity fluid filters such as coal slurry.
Along with the oil supply anxiety, the becoming increasingly conspicuous of the seriously polluted and problem such as transportation difficulty etc. of coal combustion, water-coal-slurry is carried out pipeline and is carried just with its combustion with reduced pollutants, replaces advantage such as oil and is subjected to countries in the world and extensively payes attention to.Directly under the leadership of China water-coal-slurry of coal magnificent United Center, at first carried out the cool water mixture burning basic research in 1981, and obtain the success of laboratory lab scale, after this carry out intermediate experiment together and achieve success with Beijing papermaking one factory by Zhejiang University.Carry out type approval test at present, and beginning power station oil burning boiler retrofitted for firing coal-water slurry preliminary preparation.
Carry the development of coal from now on along with the high-concentration coal-water slurry pipeline, the application of water-coal-slurry will be more extensive.But coal slurry phenomenons such as nozzle obstruction occur in the tank skin fouling reasons such as entering pipeline that comes off in the time of may infiltrating external foreign material or long-time running owing to coal slurry in transportation and handling procedure, has a strong impact on atomization quality or stops up fully, even be forced to blowing out.Therefore how to guarantee to enter the prerequisite that nozzle coal slurry quality is long-term continuous burning of water-coal-slurry and safe operation of the boiler, be to be badly in need of one of key issue that solves in the water-coal-slurry popularization process, for this reason, many units propose to arrange in the stokehold imagination of filter, to guarantee the quality of coal slurry.At present, in coal serous system, use the oscillatory type screen cloth both at home and abroad usually, also select the sealed pot strainer of manual or electronic cleaning for use, all the ubiquity mesh easily stops up and causes resistance to decrease the excessive even filter screen of power to break, simultaneously, to the foreign material of some special shape, can't filter totally as sheet, filament thing, and complex structure, bulky, repair transposing part difficulty, power consumption is big.
The purpose of this utility model provides a kind of novel water-coal-slurry pot strainer.
Elaborate below in conjunction with accompanying drawing.
Accompanying drawing is a kind of novel water-coal-slurry pot strainer schematic diagram.
Main points of the present utility model are to be provided with in the device whole thin-walled screen mesh type cartridge filter 4, mistake Downlink connection section 2 on the filter cylinder, under connect return passage 7, its outside is provided with sleeve 6, the return passage lower end communicates with blow-off pipe 10 and water-coal-slurry return duct 11, linkage section is provided with forward scavenge pipe 12 of water-coal-slurry inlet tube 8 and filter, and the sleeve lower end is provided with water-coal-slurry outlet 9 and the reverse scavenge pipe 13 of filter, and (outward) is provided with cleaning brush 3 and scraper plate 5 in the cartridge filter, cleaning brush is connected with axle by bolt by bolt 14 or spring 15 and scraper plate, and drives with slowspeed machine 1. Cartridge filter processes with the metal material integral body of wear resistant corrosion resistant, has its aperture of eyelet and filter area on the barrel and decides according to volume size and nozzle requirement, but must guarantee can not pass through greater than particle and the fiber of any shape of filtering holes diameter. The aperture is 1.5～2mm on the filtration barrel, and the eyelet gross area is 8～12 times with the ratio of water-coal-slurry inlet tube sectional area. Cleaning brush adopts copper wire or stainless copper wire, and cleaning brush contacts with filtering barrel, and scraper plate and cartridge filter have certain interval. The coarse granule that the cleaning brush does not clean under zero motor drives or the coal slurry of high concentration; pass through return line; continuously underproof coal slurry is back in the grade one filter before the agitator tank, underproof coarse granule and fibrous matter can not accumulated in the filter. By blow-off pipe, regularly eliminating may deposit the bulky grain in the return passage, prevents that return duct from stopping up, when out of service as the blowdown of rinse water. When filter is stopped transport, by filter along (contrary) in the scavenge pipe flush filter and the coal slurry between outer sleeve and cartridge filter, coal slurry precipitation when preventing from stopping transport. Zero motor requires its rotating speed less than 20 rev/mins as the power of Automatic clearance.
Adopt advantage of the present utility model: 1. filtration resistance loss is low, and △ P is less than 0.1MPa, thereby need not change coal slurry pump; 2. simple and compact for structure, volume is little; 3. power consumption is low; 4. easy to maintenance, but each parts Assembling, transposing, dismounting; 5. security of operation, the reliability height; 6. can adapt to various coal slurry traffic requirements, guarantee that entering nozzle coal slurry solid sundries maximum gauge is not more than 2 millimeters. 7. have two-way water detergent line, easy to operate.
