The utility model provides a technical scheme: a gypsum discharge pump inlet pipe screen cleaning apparatus, as shown in fig. 1-3, comprising: one-level filter screen 1, one-level filter screen 1 is Y type filter screen, be provided with filter core 12 in the one-level filter screen 1, the department that links to each other of one-level filter screen 1 and second grade filter screen 6 is provided with the short joint of discharge door 13. An annular edge sealing piece 14 is arranged in the short joint 13 of the discharge door. The input of one-level filter screen 1 links to each other with the output of absorption tower 2, be provided with gypsum displacement pump entry door 3 between one-level filter screen 1 and absorption tower 2, one-level filter screen 1 links to each other with sparge water pipeline 4, be provided with one-level filter screen wash water door 5 between one-level filter screen 1 and sparge water pipeline 4, one-level filter screen 1 links to each other with second grade filter screen 6, second grade filter screen 6's device upper end is provided with the second grade filter screen apron, the material of second grade filter screen apron is rubber. Be provided with one-level filter screen blowdown door 7 between one-level filter screen 1 and second grade filter screen 6, second grade filter screen 6 links to each other with second grade filter screen mud discharging pipe 8, the output of one-level filter screen 1 links to each other with gypsum displacement pump 9's input, be provided with gypsum displacement pump discharge door 10 between one-level filter screen 1 and gypsum displacement pump 9, be provided with gypsum displacement pump outlet door 11 on the output of gypsum displacement pump 9.
The utility model discloses an optimize current filter screen structure, add sparge water pipeline 4 on 1 upper portion of Y type one-level filter screen, improve the filter core terminal surface blind plate structure of 1 inside of one-level filter screen, become annular banding piece 14+ discharge gate short connector 13+ pneumatic butterfly valve's structure. When the inlet filter screen is blocked, the inlet door 3 of the gypsum discharge pump and the outlet door 11 of the gypsum discharge pump are closed, the flushing water door 5 of the first-stage filter screen and the butterfly valve of the end face of the filter element are opened, and impurities in the first-stage filter screen 1 are flushed out from the position of the discharge door 10 of the gypsum discharge pump by means of flushing water. Install a second grade filter screen 6 additional at filter screen discharge tube end, 1 discharges of one-level filter screen contains impurity thick liquid secondary filter, and the thick liquid flows into the trench through second grade filter screen 6, and impurity is retained on 6 upper portions of second grade filter screen, can clear up under the condition of not stopping transport, not dismantling equipment, has eliminated the safety risk of filter screen clearance, has improved the automatic operation level of system.
The filter screen cleaning process flow has two kinds:
filter screen cleaning work flow I (conventional use mode)
1. The gypsum discharge pump 9 is stopped; the gypsum discharge pump discharge door 10 is closed; the gypsum discharge pump outlet door 11 is closed.
2. Gypsum discharge pump inlet door 3 is closed
3. The gypsum discharge pump Y-shaped first-level filter screen sewage discharge door 7 is closed
4. The gypsum discharge pump Y-shaped primary filter screen flushing water door 5 is opened, and is closed after the time delay of 30S.
5. The gypsum discharge pump Y-shaped primary filter screen sewage discharge door 7 is closed, and the delay time of 60S is closed.
6. The flow ends.
This flow mainly washes through the sparge water impurity in to the filter screen, discharges to gypsum discharge pump second grade filter screen 6 through filter screen discharge door, and impurity is retained on filter screen upper portion, and the thick liquid need consume the process water with rivers income trench during the use. The procedure is a conventional manner of use.
Filter screen cleaning working process two (used when the inlet filter screen is seriously blocked)
1. The gypsum discharge pump 9 is stopped; the gypsum discharge pump outlet door 11 is closed.
2. The gypsum discharge pump inlet door 3 is closed.
3. The gypsum discharge pump discharge door 10 is closed.
4. The gypsum discharge pump Y-shaped primary filter screen sewage discharge door 7 is opened, and is closed after 60S delay.
5. The gypsum discharge pump inlet door 3 is opened and time delay 10S is closed.
6. The flow ends.
The filter screen is washed by the slurry in the absorption tower and is discharged through the filter screen discharge door. The process water is not consumed when the device is used. The thick liquid gets into from Y type one-level filter screen entry section, can prevent that the palirrhea filter screen front portion pipeline that goes into of impurity, and gypsum displacement pump entry pipeline specification is DN150 simultaneously, and the flow is more DN50 sparge water and obviously increases, can improve the washing effect.
The two related valves of the flushing process can be provided with a manual door or a pneumatic door, and the flushing process can be integrated on the DCS after the pneumatic door is arranged, so that the automatic cleaning of the filter screen is realized.
The optimization process has the following relevant effects:
the main optimization content of the Y-shaped primary filter screen of the gypsum discharge pump is that a blind plate at the end part of the original filter screen is optimized into a Y-shaped filter screen discharge door short joint 13 and a filter element annular sealed edge 14, and a washing water pipeline 4 is additionally arranged above the filter screen. 13, after optimization, a valve can be added at the sewage discharge part of the filter screen to realize online impurity discharge; 14, after optimization, the Y-shaped filter screen filter element can be positioned under the condition of changing the structure, and the situation that the fit position of the filter element and the filter screen body has a gap to cause impurities to flow into rear-section equipment is prevented; 4, the online water washing function of the filter screen can be realized after optimization.
The gypsum discharge pump secondary filter screen 6 is additionally provided with equipment according to actual production, and impurities discharged by the Y-shaped primary filter screen 1 through the Y-shaped primary filter screen blow-down door 7 can be retained at the upper part of the filter element of the open secondary filter screen 6 after the secondary filter screen 6 is added, so that the impurities are prevented from flowing into a trench and entering the desulfurization absorption tower system again; meanwhile, sundries on the upper part of the filter element of the second-stage filter screen 6 can be cleaned when the Y-shaped first-stage filter screen 1 does not discharge dirt, so that the continuous operation of the equipment is realized, and the function of cleaning impurities of the equipment is realized without stopping the operation.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
