Heisui River filter 2 includes open-topped shell 11, and flange 22 is equipped at the top of shell 11, and capping 12 is flange Lid, flange 22 are bolted with blind flange, sealing ring 21 are equipped between shell 11 and capping 12, on the inner wall of shell 11 Circumferentially arranged with boss 13, it is equipped with filter basket 14 in the inside of shell 11, the top exterior walls of filter basket 14 are equipped with outer, outer overlap joint On boss 13, the edge of outer is contacted with the inner wall of shell 11, and ultrasonic oscillator 20 is equipped on the inner wall of shell 11, this Ultrasonic oscillator 20 used in the examples is the ultrasonic wave of model gdq -2072t of luminous point ultrasonic equipment Co., Ltd Oscillator 20 is equipped with Heisui River import 15 in the side wall of the shell 11 of the lower section of boss 13, the shell 11 in the top of boss 13 Side wall is equipped with filtering water outlet 16.

Carbon dioxide pipe is equipped on Heisui River input pipe 1 between import of the import to recoil tube 4 of Heisui River input pipe 1 17, it is equipped with carbon dioxide air source 18 in the import of carbon dioxide pipe 17, the 5th electrically-controlled valve 19 is equipped on carbon dioxide pipe 17.

It further includes PLC controller 23, and the producer of the PLC controller 23 in the present embodiment is Rockwell, model Ics, PLC controller 23 and blowdown electrically-controlled valve 7, the first electrically-controlled valve 6, the second electrically-controlled valve 8, third electrically-controlled valve 9 and the 4th electrically-controlled valve 10 electrical connections.

Working principle:

When carrying out normal filtration to Heisui River, the first electrically-controlled valve 6, the second electrically-controlled valve 8 and the 5th electrically-controlled valve 19 are opened, third electricity It controls valve 9, the 4th electrically-controlled valve 10 and blowdown electrically-controlled valve 7 to close, the Heisui River that coal gasification course generates enters Heisui River input pipe 1, dioxy Change carbon and Heisui River input pipe 1 is entered by carbon dioxide pipe 17, carbon dioxide and the input of Heisui River volume are than being 1:500, carbon dioxide Volume unit be standard cubic meter, carbon dioxide forms carbonic acid after being dissolved in water, reacts life with calcium ion, the magnesium ion in Heisui River At calcium carbonate, carbonic acid magnesium precipitate, that is, scale, calcium ion, the magnesium ion in Heisui River are tentatively eliminated, prevents follow-up system fouling tight Lead to line clogging, rupture again；Scale enters Heisui River filter 2 from Heisui River input pipe 1 with Heisui River, and scale is hacked water filter 2 intercept, and are attached on filter basket 14 and shell 11, Heisui River is after filter basket 14 filters out solid particle from the filtering of Heisui River filter 2 Water out 16 is discharged, and solid particle is deposited to 11 bottom of shell, and filtered Heisui River enters subsequent system by Heisui River efferent duct 3 System.

Heisui River filter 2 is backwashed using after eight hours, is opened the vibration of ultrasonic oscillator 20 and is fallen Heisui River filter 2 Internal scale avoids Heisui River filter 2 because filter effect weakens, filter efficiency reduces caused by fouling；PLC controller 23 to First electrically-controlled valve 6 and the 5th electrically-controlled valve 19 send shutdown signal, and the first electrically-controlled valve 6 and the 5th electrically-controlled valve 19 are closed, PLC controller 23, which send aperture to the second electrically-controlled valve 8, turns signal down, turns the aperture of the second electrically-controlled valve 8 down, and PLC controller 23 is to third electrically-controlled valve 9, the 4th electrically-controlled valve 10 and blowdown electrically-controlled valve 7 send open signal, open third electrically-controlled valve 9, the 4th electrically-controlled valve 10 and blowdown electricity Valve 7 is controlled, Heisui River enters recoil tube 4, enters Heisui River efferent duct 3 after the filtering of back-flushing filter 5, a part passes through filtering water outlet 16 enter Heisui River filter 2, and a part continues to be discharged into rear system, use the filtered Heisui River of back-flushing filter 5 as backwash Water saves water resource, and will not be to polluting inside filter basket 14, and during the backwash process, Heisui River also will continue to backward Continuous system discharge, will not influence the operation of system, improves work efficiency；Solid particle on the outside of strainer is washed out simultaneously by back-flushing It is discharged together with the solid particle of 11 bottom of shell by sewage pipe, ten minutes later to the backwash of Heisui River filter 2, PLC control Device 23 sends open signal to the first electrically-controlled valve 6 and the second electrically-controlled valve 8, opens the first electrically-controlled valve 6 and the second electrically-controlled valve 8, PLC control Device 23 processed sends aperture to the 5th electrically-controlled valve 19 and tunes up signal, tunes up the aperture of the 5th electrically-controlled valve 19, and PLC controller 23 is to third Electrically-controlled valve 9, the 4th electrically-controlled valve 10 and blowdown electrically-controlled valve 7 send shutdown signal, close third electrically-controlled valve 9,10 and of the 4th electrically-controlled valve Blowdown electrically-controlled valve 7 continues to carry out normal filtration to Heisui River.It is automatically controlled to blowdown electrically-controlled valve 7, first by 23 timing of PLC controller Valve 6, the second electrically-controlled valve 8, third electrically-controlled valve 9 and the transmission of the 4th electrically-controlled valve 10 open or close signal, realize to Heisui River filter 2 Backwash automatic control, save manpower, reduce the labor intensity of worker.

Filter basket 14 is set inside Heisui River filter 2, and filter area is big, and filter efficiency is high, when damaged needs occurs in filter basket 14 When replacement, it can directly open 12 pairs of filter baskets 14 of capping and replace, it is simple to operate.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
