Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to gasification wastewater treatment equipment. Background Art

[0002] In the industrial production process, coal gasification technology is an important process for converting coal into combustible gas. Although this process can effectively improve energy efficiency, it also produces a large amount of wastewater. These wastewaters contain a variety of harmful substances, such as phenols, ammonia nitrogen, heavy metals, etc. If they are directly discharged without treatment, they will cause serious pollution to the environment. Therefore, it is particularly important to effectively treat and recycle coal gasification wastewater.

[0003] Traditional flocculation sedimentation equipment has certain limitations in treatment efficiency and separation effect; for example, insufficient mixing of wastewater and flocculant results in poor flocculation effect. The usual optimization method is to stir the water body, but generally the entire water body is stirred, which causes the stirred water body to be in a rotating state, which can easily cause the sediment at the bottom of the treatment equipment to be lifted up, affecting the accumulation of sediment. In addition, when the existing equipment discharges sediment, it is usually necessary to stop the wastewater treatment process, discharge the sewage from the entire equipment, and then separate the solids, and then continue to introduce sewage for sedimentation, so that the sedimentation stirring and sediment separation processes cannot be carried out at the same time, resulting in low efficiency. For this reason, a gasification wastewater treatment equipment is needed to solve the existing deficiencies. Summary of the invention

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention sets a stirring assembly. Since the stirring rods are longitudinally distributed at different heights of the treatment barrel, the rotation of the stirring rods can control the local flow of wastewater outside the stirring rods to avoid the flow of the entire water body in the treatment barrel. The local water flow can accelerate the reaction of wastewater and flocculant, and can also reduce the water flow at the top of the slow flow assembly, thereby facilitating the generation of sediment.

Since the connecting ring is rotatably connected to the support column, the sealing block and the guide column are driven to move downward synchronously. However, since the guide column is movably connected to the inside of the guide groove, and the guide groove is in a broken line shape, the sealing block is rotated downward to the top of the through groove and continues to move. The sealing block is stuck in the inside of the through groove, so that the sediment on the top of the sealing disk cannot continue to flow through the through groove to the separation layer. This is conducive to achieving the simultaneous stirring of the wastewater in the upper part of the treatment cylinder and the separation of the sediment in the lower part.

[0028] 4. The present invention provides a diversion assembly. When the liquid in the sediment is discharged, the support column is controlled to move upward until the sealing platform is completely inserted into the bottom opening of the guide plate. At this time, the sealing needle is reinserted into the drainage hole to avoid the drainage hole being blocked by solid matter and at the same time restore the surface of the diversion plate to a smooth state, which is conducive to the sliding of the remaining solid matter.

[0029] 5. The present invention controls the lifting and lowering of the sealing platform through the switching component set up by the support column. When the support column controls the sealing platform to move downward along the bottom opening of the guide plate, under the action of the connecting frame, the sealing plates are driven to respectively snap into the openings of the solid pipes to seal the solid pipes. Therefore, only at this time can the sediment flow along the opening of the guide plate to the inside of the treatment layer, avoiding the sediment from being directly discharged from the opening of the solid pipe.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and 10 As shown, the present invention provides a technical solution: a gasification wastewater treatment device, comprising a treatment barrel 1, the top of which is provided with a guide pipe for introducing wastewater and a feeding pipe for feeding flocculants; a support column 2 movably penetrates the treatment barrel 1; a lifting component 3 is located at the top of the treatment barrel 1, and is used to control the lifting of the support column 2; a stirring component 4 is connected to the inside of the treatment barrel 1, and is used to accelerate the reaction of the flocculant and the wastewater; a slow flow component 5 is located directly below the stirring component 4, and is used to reduce the disturbance of the water flow at its bottom; a sealing disk 6 is connected to the inside of the treatment barrel 1, and the sealing disk 6 is penetrated by a plurality of through grooves 11 for the sediment to pass through; a sealing component 7 is located directly below the slow flow component 5 Below and directly above the sealing plate 6, it is used to prevent the sediment from passing through the inside of the through groove 11; the guide plate 8 is connected to the inside of the treatment tube 1 and is located directly below the sealing plate 6, and is used to gather the sediment. The space between the guide plate 8 and the sealing plate 6 is a partition layer; the diverter component 9 is located at the bottom of the treatment tube 1, and is used to separate the wastewater and solids in the sediment. The space between the diverter component 9 and the guide plate 8 is the treatment layer; and the switching component 10 is located between the guide plate 8 and the diverter component 9, and is used to control the sediment to enter the treatment layer. The support column 2 passes through the sealing plate 6, and the support column 2 is movably connected to the sealing plate 6, and the bottom end of the support column 2 is connected to the top end of the switching component 10.

[0045] The wastewater generated by coal gasification is introduced into the interior of the treatment tube 1 through the guide pipe at the top of the treatment tube 1, and the flocculant is fed into the interior of the treatment tube 1 through the feeding pipe. The wastewater reacts with the flocculant to cause some substances in the wastewater to flocculate together, thereby generating a precipitate inside the treatment tube 1, and the precipitate flows to the diversion layer through the groove 11. The sealing disk 6 is sealed by the switching component 10, so that the precipitate enters the treatment layer from the diversion layer, and the liquid and solid in the precipitate are separated and discharged through the diversion component 9 and the switching component 10.

[0046] like Figure 1 and Figure 3As shown, the lifting assembly 3 includes a collar 301, a connecting rod 302, a slider 303 and a hydraulic rod 304. The connecting rod 302, the slider 303 and the hydraulic rod 304 are all distributed in a circular array. The top of the connecting rod 302 is movably connected to the outside of the collar 301 through a rotating shaft, and the bottom end of the connecting rod 302 is movably connected to the top of the slider 303 through a rotating shaft. The hydraulic rod 304 is connected to the top of the processing tube 1, and the telescopic end of the hydraulic rod 304 is respectively connected to one side of the slider 303. The top of the support column 2 passes through the collar 301, and the support column 2 is connected to the collar 301. A plurality of slide grooves 12 are opened at the top of the processing tube 1, and the bottom end of the slider 303 is slidably connected to the inside of the slide groove 12.

[0047] The hydraulic rod 304 is started to control the sliders 303 to move away from each other along the slide groove 12, driving the connecting rod 302 to rotate. Since the collar 301 is connected to the support column 2, the support column 2 is driven to move downward, and vice versa, the support column 2 can be controlled to move upward.

[0048] like Figure 1 , Figure 4 and Fig. 9 As shown, the stirring assembly 4 includes a control rod 401, a main cone wheel 402, a secondary cone wheel 403 and a stirring rod 404. The main cone wheel 402 is arranged linearly in the longitudinal direction, the control rod 401 penetrates the main cone wheel 402, and the control rod 401 is connected to the main cone wheel 402. Several secondary cone wheels 403 and stirring rods 404 are arranged on the outside of each main cone wheel 402. The secondary cone wheels 403 are meshed with the main cone wheel 402. The stirring rods 404 penetrate the secondary cone wheels 403 respectively, and the stirring rods 404 are connected to the secondary cone wheels 403. The stirring assembly 4 also includes a servo motor 405. The main cone wheel 402 is movably connected to the inside of the support column 2 through a rotating rod, the servo motor 405 is connected to the inside of the support column 2, and the servo motor 405 is connected to the top of the support column 2. The secondary cone wheels 403 are movably connected to the inside of the support column 2 through one end of the stirring rod 404, and the stirring blades of the stirring rod 404 are located inside the processing cylinder 1.

[0049] Start the servo motor 405 to drive the control rod 401 to rotate, thereby driving the main cone wheel 402 to synchronously rotate the rod. Since the secondary cone wheel 403 is meshed with the main cone wheel 402, the secondary cone wheel 403 is controlled to drive the stirring rod 404 to rotate, and the stirring blades outside the stirring rod 404 are used to stir the wastewater. Since the stirring rod 404 is longitudinally distributed at different heights of the treatment tube 1, and the rotation of the stirring rod 404 can control the local wastewater flow outside the stirring rod 404, avoiding the flow of the entire water body of the treatment tube 1. The local water flow can accelerate the reaction of the wastewater and the flocculant, and can also reduce the water flow at the top of the slow flow component 5, thereby facilitating the generation of sediment.

[0050] like Figure 1 and Figure 5As shown, the slow flow assembly 5 includes a bracket 501 and a slow flow sheet 502. The bracket 501 is connected to the inside of the treatment tube 1. The slow flow sheet 502 is arranged in a circular shape, and the bottom end of the slow flow sheet 502 is connected to the top end of the bracket 501. The slow flow sheets 502 are all wavy in shape. The support column 2 passes through the center of the bracket 501, and the support column 2 is movably connected to the bracket 501.

[0051] The slow-flow sheet 502 is wavy in shape and is arranged in a staggered manner as shown in the figure, further reducing the flow of water below the stirring component 4, thereby further ensuring the generation of sediment. At the same time, the sediment passes through the bracket 501 and flows to the surface of the sealing disk 6.

[0052] like Figure 1 and Figure 6 As shown, the sealing assembly 7 includes a connecting ring 701, a sealing block 702 and a guide column 703. The sealing blocks 702 and the guide columns 703 are distributed in a circular array. The sealing blocks 702 are trapezoidal and connected to the outside of the connecting ring 701. The guide columns 703 are respectively connected to the outside of the sealing blocks 702. The support columns 2 pass through the connecting ring 701, and the support columns 2 are rotatably connected to the connecting ring 701. The sealing blocks 702 are respectively matched with the through grooves 11. The inner wall of the processing cylinder 1 is provided with a plurality of guide grooves 13. The guide grooves 13 are all in a broken line shape. The guide columns 703 are respectively movably connected to the guide grooves 13.

[0053] Since the connecting ring 701 is rotatably connected to the support column 2, the sealing block 702 and the guide column 703 are driven to move downward synchronously. However, since the guide column 703 is movably connected to the inside of the guide groove 13, and the guide groove 13 is in a broken line shape, the sealing block 702 rotates downward to the top of the through groove 11 and continues to move. The sealing block 702 is stuck in the inside of the through groove 11, so that the sediment on the top of the sealing disk 6 cannot continue to flow through the through groove 11 to the separation layer.

[0054] like Figure 1 and Figure 7As shown, the flow dividing assembly 9 includes a solid pipe 901, a liquid pipe 902 and a flow dividing plate 903. The solid pipe 901 is connected to the bottom end of the treatment tube 1, the liquid pipe 902 is connected to the inner side of the solid pipe 901, and the flow dividing plate 903 is connected to the inner side of the liquid pipe 902. The flow dividing plate 903 is located directly below the guide plate 8. The sealing plate 6, the flow dividing plate 903 and the guide plate 8 are all conical. The tip of the sealing plate 6 and the tip of the flow dividing plate 903 are both facing upward, and the tip of the guide plate 8 is facing downward. The flow dividing assembly 9 also includes a mounting frame 904, a sealing needle 905, a reset spring 906 and a connecting rod 907. The connecting rod 9 07 is connected to the top center of the mounting bracket 904, the top of the connecting rod 907 passes through the top of the diverter disk 903, and the connecting rod 907 is movably connected to the diverter disk 903, the reset spring 906 is sleeved on the outside of the connecting rod 907, the bottom end of the reset spring 906 is connected to the top of the mounting bracket 904, and the bottom end of the reset spring 906 is connected to the bottom end of the diverter disk 903, the sealing needles 905 are distributed in a circular array, the bottom ends of the sealing needles 905 are all connected to the top of the mounting bracket 904, and a plurality of drainage holes 14 are provided at the bottom end of the diverter disk 903, and the sealing needles 905 are respectively adapted to the drainage holes 14.

[0055] 903, and finally flows out from the bottom end of the liquid pipe 902. After the liquid in the sediment is discharged, the support column 2 is controlled to move upward until the sealing platform 1001 is completely stuck in the bottom opening of the guide plate 8. At this time, the sealing needle 905 is reinserted into the interior of the drainage hole 14 to prevent the drainage hole 14 from clogging the solid matter and at the same time restore the surface of the diverter plate 903 to a smooth state, which is conducive to the sliding of the remaining solid matter. At this time, the sealing plate 1003 is separated from the top opening of the solid pipe 901. Since the outer side surface of the diverter plate 903 is set as a slope, the solid slides to the opening of the solid pipe 901 under the action of its own gravity and is discharged through the bottom opening of the solid pipe 901, thereby completing the separation of the liquid and solid in the sediment.

[0056] like Figure 1 and Figure 8As shown, the switching assembly 10 includes a sealing platform 1001, a connecting frame 1002 and a sealing plate 1003. The sealing platform 1001 is connected to the center of the connecting frame 1002. The sealing platform 1001 is in a truncated cone shape, and the sealing platform 1001 is adapted to the bottom opening of the guide plate 8. The top end of the sealing platform 1001 is connected to the bottom end of the support column 2, and the bottom end of the sealing platform 1001 is connected to the top end of the connecting rod 907. The sealing plates 1003 are distributed in a circular array, and the top ends of the sealing plates 1003 are all connected to the bottom end of the connecting frame 1002. The sealing plates 1003 are adapted to several inlet ends of the solid pipe fitting 901 respectively.

[0057] The sealing platform 1001 is controlled to rise and fall by the support column 2. When the sealing platform 1001 is controlled by the support column 2 to move downward along the bottom opening of the guide plate 8, the sealing plate 1003 is driven to respectively snap into the opening of the solid pipe 901 under the action of the connecting frame 1002 to seal the solid pipe 901. Therefore, only at this time can the sediment flow along the opening of the guide plate 8 to the inside of the treatment layer, thereby preventing the sediment from being directly discharged from the opening of the solid pipe 901. In addition, the downward movement of the round table simultaneously causes the connecting rod 907 to move downward, driving the mounting frame 904 to move downward, causing the reset spring 906 to stretch and lengthen, controlling the sealing needle 905 to respectively engage with the discharge port 906. The liquid holes 14 are separated, and then the liquid in the sediment entering the treatment layer also flows to the bottom of the diverter plate 903 through the drainage holes 14, and flows down from the inner side of the mounting frame 904. At this time, the sealing needle 905 is reinserted into the drainage hole 14 to prevent the drainage hole 14 from clogging the solid matter and at the same time restore the surface of the diverter plate 903 to a smooth state, which is conducive to the sliding of the remaining solid matter. At this time, the sealing plate 1003 is separated from the top opening of the solid pipe 901. Since the outer side surface of the diverter plate 903 is set as a slope, the solid slides to the opening of the solid pipe 901 under the action of its own gravity and is discharged through the bottom opening of the solid pipe 901.

[0058] Working principle: when in use, first, the wastewater generated by coal gasification is introduced into the interior of the treatment tube 1 through the guide pipe at the top of the treatment tube 1, and the flocculant is fed into the interior of the treatment tube 1 through the feeding pipe. The wastewater reacts with the flocculant, so that some substances in the wastewater are flocculated together, thereby generating sediment inside the treatment tube 1, and the sediment flows to the diversion layer through the groove 11. At the same time, the servo motor 405 is started to drive the control rod 401 to rotate, thereby driving the main cone wheel 402 to rotate synchronously. Since the secondary cone wheel 403 is meshed with the main cone wheel 402, the secondary cone wheel 403 is controlled to drive the stirring rod 404 to rotate, and the stirring blades outside the stirring rod 404 are used to stir the wastewater. Since the stirring rod 404 is longitudinally distributed at different heights of the treatment tube 1, and the rotation of the stirring rod 404 can control the local wastewater flow outside the stirring rod 404, avoiding the flow of the entire water body of the treatment tube 1. The local water flow can accelerate the reaction of the wastewater and the flocculant, and can also reduce the water flow at the top of the slow flow component 5. The production of sediment is convenient; in addition, the slow flow sheet 502 is wavy, and the slow flow sheet 502 is arranged in a high and low staggered manner as shown in the figure, which further reduces the flow of water under the stirring component 4, thereby further ensuring the generation of sediment, and the sediment passes through the bracket 501 and flows to the surface of the sealing disk 6; when the sediment on the surface of the sealing disk 6 reaches the level that needs to be discharged, the hydraulic rod 304 is started to control the slider 303 to move away from each other along the slide groove 12, driving the connecting rod 302 to rotate, and since the collar 301 is connected to the support column 2, the support column 2 is driven to move downward; since the connecting ring 701 is rotatably connected to the support column 2, the sealing block 702 and the guide column 703 are driven to move downward synchronously, but since the guide column 703 is movably connected to the inside of the guide groove 13, and the guide groove 13 is in a broken line shape, the sealing block 702 rotates downward to the top of the through groove 11, and continues to move, and the sealing block 702 is stuck in the inside of the through groove 11, so that the sediment on the top of the sealing disk 6 cannot continue to flow to the separation layer through the through groove 11;The sediment in the separation layer gathers toward the bottom center of the guide plate 8 under the action of the guide plate 8. Since the sealing platform 1001 is in the shape of a truncated cone, that is, the sealing platform 1001 is composed of a cone part and a cylindrical part, and the cylindrical part of the sealing platform 1001 is connected to the connecting frame 1002, when the support column 2 controls the sealing platform 1001 to move downward along the bottom opening of the guide plate 8, the connecting frame 1002 drives the sealing plate 1003 to be respectively inserted into the opening of the solid pipe 901 to seal the solid pipe 901. Therefore, only when the sediment is The sediment can flow along the opening of the guide plate 8 to the inside of the treatment layer, avoiding the sediment from being discharged directly from the opening of the solid pipe 901. In addition, the downward movement of the truncated table also causes the connecting rod 907 to move downward, driving the mounting frame 904 to move downward, so that the reset spring 906 stretches and lengthens, and controls the sealing needle 905 to separate from the drainage hole 14 respectively. Subsequently, the liquid in the sediment entering the treatment layer also flows to the bottom end of the diverter plate 903 through the drainage hole 14, and flows down from the inner side of the mounting frame 904, and finally flows out from the bottom end of the liquid pipe 902. After the liquid in the solid is discharged, the support column 2 is controlled to move upward until the sealing platform 1001 is completely stuck in the bottom opening of the guide plate 8. At this time, the sealing needle 905 is reinserted into the drainage hole 14 to prevent the drainage hole 14 from being blocked by solid matter and at the same time restore the surface of the diverter plate 903 to a smooth state, which is conducive to the sliding of the remaining solid. At this time, the sealing plate 1003 is separated from the top opening of the solid pipe 901. Since the outer side of the diverter plate 903 is set as a slope, the solid slides to the opening of the solid pipe 901 under the action of its own gravity, and The solid waste is discharged through the bottom opening of the solid pipe 901, thereby completing the separation of the liquid and solid in the sediment. During the longitudinal movement of the support column 2, the stirring rod 404 can be controlled to rotate or stop. If the stirring rod 404 rotates, the sealing disk 6 is in a closed state, and the upper part of the treatment tube 1 can continue to precipitate the wastewater, while the lower part of the treatment tube 1 is used to separate and discharge the sediment. The two do not affect each other, and there is no need to wait until the wastewater is discharged before discharging the solid matter in the sediment, thereby effectively improving the wastewater treatment efficiency. ;
