Description

Technical Field

[0001] The present invention relates to the field of gypsum waste liquid treatment equipment, and specifically to a desulfurization filtration device for gypsum processing. Background Art

[0002] Wet flue gas desulfurization with gypsum mainly removes sulfides and slight dust contained in wastewater. Soluble substances contained in the produced weakly acidic wastewater include not only sulfides but also chlorides, nitrates, etc. Existing desulfurization filtration devices mostly adopt an adsorption filter screen structure. During the actual desulfurization filtration process of gypsum waste liquid, we found the following defects: 1. Impurities are easily attached to the surface of the adsorption filter screen structure, and the percolation structure is prone to blockage, affecting the filtration efficiency; 2. The waste liquid cannot circulate inside the treatment container structure, resulting in easier sinking and caking of impurities in the waste liquid, increasing the cleaning difficulty; 3. A single pump is used to suck and discharge the liquid treated by the adsorption filter screen structure, greatly increasing the amount of impurities attached to the surface. Therefore, a desulfurization filtration device for gypsum processing is proposed for the above problems. Summary of the Invention

The output port of the internal circulation pump 14 is communicated with the middle space in the processing box body 1 through a first conduit 15, and one end of the distributed first conduit 15 is installed at the corresponding part of the annular plate 9;

[0029] Combined with Figure 1 and Figure 3 As shown, when the sulfur-containing gypsum processing waste liquid enters the processing box body 1 filled with liquid at a fixed time through the inlet pipe 21, the internal circulation pump 14 is operated to make the processing liquid enter from the conical cover 19 and flow back to the processing box body 1 through the mutual conduits, achieving the effect of internal circulation flow. At the same time, by arranging the vortex formation guide plate 1901 on the inner wall of the conical cover 19, the liquid entering the conical cover 19 is in a swirling shape, and the swirling centrifugal force can be used to accelerate the sinking speed of particulate matter. The sedimentation bucket 16 is provided to hold the sinking particulate impurities, reducing the flow of particulate impurities to precipitate into the processing box body 1.

[0030] A rubber sheet 10 is installed in the annular hole of the annular plate 9.

The transmission pipe 22 is internally communicated with the adapter pipe 3 through a through hole 2201, and the adapter pipe 3 is communicated with the corresponding part of the outflow conduit 6 through a short pipe 26;

[0035] Referring to Figure 2 As shown in the figure, when the liquid processed by the tubular filter element 2 enters the inside of the transmission pipe 22, under the action of the pressing and infiltration force, the processed liquid enters the outflow conduit 6 through the suction pipe 24, the through hole 2201, the adapter pipe 3, and the short pipe 26 until it is discharged, playing a role of filtering and guiding the discharge.

The top closed end of the transmission pipe 22 is connected to the shaft end of the waterproof motor 8. By operating the waterproof motor 8, the tubular filter element 2 connected through the transmission pipe 22 is driven to rotate at a high speed. Combined with the ultrasonic generator 4 located on one side of the tubular filter element 2, the adhesion of impurities on the surface of the filtering structure is greatly reduced, the cleaning cycle of the filtering structure is prolonged, and the desulfurization filtering efficiency is improved.

[0039] Further, both ends of the transfer pipe 3 are rotationally connected to the corresponding parts of the transmission pipe 22 through sealed bearings.

[0040] Further, a plug cover 25 is installed at the port at the bottom end of the transmission pipe 22, and liquid seepage holes are distributed on the surface of the part of the transmission pipe 22 located inside the tubular filter element 2.

[0043] When the present invention is in use, as shown in combination with Figure 1 and Figure 3 When the sulfur-containing gypsum processing waste liquid enters the treatment box body 1 filled with liquid at a fixed time through the introduction pipe 21, the internal circulation pump 14 is operated to make the treatment liquid enter from the conical cover 19 and flow back to the treatment box body 1 again through the mutual conduit, achieving the effect of internal circulation flow. At the same time, by arranging eddy current forming guide plates 1901 on the inner wall of the conical cover 19, the liquid entering the conical cover 19 is in a vortex shape, and the vortex centrifugal force can be used to accelerate the sinking speed of particulate matter, and the sedimentation bucket 16 is combined to hold the sinking particulate impurities, reducing the flow of particulate impurities to precipitate into the treatment box body 1;

[0044] With reference to Figure 1 and Figure 4 As shown, for the specific implementation operation of the telescopic agitation structure: under the action of the air pump 11, the pneumatic controller 12 and the air change electric control valve 13, the sealed space below the ring plate 9 can be inflated and expanded and replaced with air for resetting. By using the inflation and expansion, the rubber sheet 10 bulges outward, and the liquid filled above is pushed, and in combination with the fact that the introduction pipe 21 is in a closed and unblocked state at this time, the waste liquid pressure is infiltrated into the tubular filter element 2, and each time the pressure infiltration filtration is completed, the introduction pipe 21 is opened to inhale the waste liquid again;

[0045] Combined with Figure 3 As shown, the booster water pump conveys the neutralizing liquid through the pipe body and sprays it out from the liquid spraying pipe 28, which can be fully mixed with the waste liquid flowing through the third conduit 18, achieving the effect of neutralizing sulfur-containing substances;

[0046] With reference to Figure 2As shown, when the liquid processed by the tubular filter element 2 enters the interior of the transmission pipe 22, under the pressure osmosis force, the processed liquid enters the outflow conduit 6 through the suction pipe 24, the circulation holes 2201, the adapter pipe 3, and the short pipe 26 until it is discharged, playing the role of filtering and guiding the discharge. By operating the waterproof motor 8, the tubular filter element 2 connected through the transmission pipe 22 is driven to rotate at a high speed, and in combination with the ultrasonic generator 4 located on one side of the tubular filter element 2, the adhesion of impurities on the surface of the filtering structure is greatly reduced, the cleaning cycle of the filtering structure is extended, and the desulfurization filtering efficiency is improved.
