Description

Technical Field

[0001] The present invention relates to the technical field of tungsten ore processing equipment, and in particular to a tungsten ore raw material roasting flue gas spraying wastewater treatment system. Background Art

[0002] High-purity tungsten ore generally requires no pretreatment before entering the pure tungsten compound production process. However, with the increasing scarcity of tungsten ore resources, ores with complex compositions are becoming increasingly common. Therefore, pretreatment of the tungsten ore before decomposition is beneficial for subsequent production. Currently, roasting is a common pretreatment method. This involves burning off chemicals left over from gravity separation and flotation, volatilizing arsenic and sulfur-containing minerals, improving the decomposition rate, and, more importantly, reducing tin leaching. The roasting process generates a large amount of flue gas, which contains toxic gases such as SO₂ and As₂O₃. These gases need to be sprayed with clean water to absorb them and prevent atmospheric pollution. The resulting spray wastewater also requires a series of sedimentation treatments before discharge. However, traditional wastewater treatment systems are bulky, require multiple sedimentation tanks, and require significant time for the suspension to settle. This results in low wastewater treatment efficiency and is unsuitable for treating small volumes of flue gas and wastewater. A new treatment equipment is needed to address these issues.

[0023] In this embodiment, the bottoms of the two side chambers separated by the folding seat 6 during movement are connected by a three-way mechanism. The three-way mechanism includes a three-way cylinder 17. The three-way cylinder 17 is installed on the back of the sedimentation box 1. The upper and lower connecting ports 1701 of the three-way cylinder 17 are respectively connected to the bottom plate of the folding seat 6 and the bottom surface of the sedimentation box 1. When the bottom plate is completely retracted into the equipment room 101, the vertical plate of the folding seat 6 closes the upper connecting port 1701. The three-way cylinder 17 slides vertically in the cylinder body to connect the valve block 18. The valve block 18 is threadedly connected to the output shaft of the control motor 19. The control motor 19 is installed on the top of the three-way cylinder 17. A drain port 1702 is provided on one side of the lower connecting port 1701. The drain port 1702 is connected to the input end of the emptying pump 20 with a control valve, and the output end of the emptying pump 20 is connected to the adsorption filter cartridge 21.

[0024] The working principle of the present invention is as follows: In the treatment process of tungsten ore roasting flue gas spray wastewater, it is necessary to first add CaO to adjust the pH value to 7-9 to produce CaSO4·2H2O precipitation; then add H2O2 to remove AS in the wastewater. 3+ Restore to AS 5+ Then, FeCl₃ is added to form FeASO₄ and Fe(OH)₃ flocs, followed by Na₂S to form As₂S₃ and PbS precipitates. PAM is then added to completely settle the flocs, and finally, CaCl₂ is added to form CaF₂ precipitates. All of these settling agents are placed in the single chamber of reagent tank 36 for later use.

[0025] When spray wastewater needs to be treated, open the feed pipe 34 to inject the wastewater into the mixing box 33, and inject the sedimentation agent into the box from the reagent tank 36. Start the mixing motor 35 to mix the two, and then send the generated suspension, sediment, etc. to the gate valve 37 and discharge them into the sedimentation box 1. At this time, the bottom plate of the folding seat 6 is completely retracted into the equipment room 101, and the vertical plate of the folding seat 6 is in contact with the side wall of the sedimentation box 1. After waiting for a period of time, part of the sediment settles to the bottom of the box, and the liquid pushing motor 16 is started to drive the folding seat 6 to move slowly to the opposite side, and the two sides of the vertical plate gradually separate the two chambers. Under the push of the vertical plate, Figure 1 The wastewater in the middle left chamber is squeezed into the filter cartridge 7, and the clear liquid after the suspended particles are filtered out by the filter sleeve 703 falls into the right chamber from the drainage hole 704. When the vertical plate contacts the opposite side of the box wall, the gate 22 is opened, the bottom cleaning cylinder 2 is started to push the sludge settled at the bottom of the box into the feed hopper 2401, the spinning motor 25 is started to drive the pressing drum 3 to rotate, the spiral blade 301 continuously presses the sludge into the mud collecting cover 26, the mud pushing cylinder 28 is started to push the mud pushing plate 29 for auxiliary compaction, and the filtrate squeezed out of the sludge enters the inner cavity of the pressing drum 3 from the leak cap 302, and is then pumped into the mixing box 33 by the circulation pump 5 through the rotary joint 4 for standby use. During the filtration process, the electric heating wire 27 can be started to heat the sludge to help the residual water in the sludge evaporate and drain.

[0026] When the sludge at the bottom of the tank is completely cleared, the bottom cleaning cylinder 2 is reset, the gate plate 22 is closed, and the control motor 19 is started to move the valve block 18 from the top dead center to the bottom dead center, connecting the upper and lower sides of the bottom plate of the folding seat 6. The folding seat 6 is then moved in the opposite direction to reset the liquid in the right chamber to the left chamber through the connection port 1701. The same type of sedimentation agent is injected into the mixing box 33 again to mix with the filtrate, and then the gate valve 37 is opened to put the mixed liquid into the sedimentation tank 1 to start the next round of sedimentation. After repeating several times to ensure that all the sediment of this type has settled and the filtration is completed, the mud cover motor 32 is started to open the mud collecting cover 26, and the mud pusher 29 is used to push all the filter residue into the corresponding partition of the material tray 38. Then the mud collecting cover 26 is reset and the turntable motor 39 is started to rotate the next partition to the bottom of the mud discharge assembly. At the same time, the folding seat 6 is located at the far right, and the filter cartridge 7 passes through the loading hole 103. The translation motor 9 is started to move the base column 10, so that the filter cartridge motor 14 is connected to the filter cartridge 7. The electromagnet 15 is started to attract the metal plate 701, and the filter cartridge motor 14 is started to screw and release the filter cartridge 7. The base column 10 moves back and takes out the filter cartridge 7. The rotary table motor 11 is started to drive the cross joint 13 to rotate, so that the next filter cartridge 7 is aligned with the loading hole 103. Then the operation is reversed to install a new filter cartridge 7 on the folding seat 6 and start the next sediment. When all the sediment is settled, the emptying pump 20 is turned on, and the treated wastewater is adsorbed by the adsorption filter cartridge 21 and then discharged.

[0027] The system does not require multiple sedimentation tanks for sedimentation, occupies a small area, has a compact structure and high integration, can effectively separate a variety of precipitates, uses active filtration to adsorb particles in the suspension, improves processing efficiency, greatly reduces sedimentation time, and is integrated, efficient, and fully automatic.
