Description

Technical Field

[0001] This invention relates to the field of municipal solid waste incineration slag wastewater technology, specifically to a waste incineration slag water circulation and graded sedimentation treatment device and its control method. Background Technology

[0002] However, as people's material living standards continue to improve, the above-mentioned solutions will adopt high-temperature incineration to treat household waste. However, after high-temperature incineration, a certain amount of incineration slag will remain. This incineration slag contains materials such as stones, metal particles, and slag ash. Stones and other larger materials can be separated by workers or screening mechanisms, but metal particles are usually separated by water washing.

[0003] Patent publication number CN112299596A discloses a wastewater recycling and grading sedimentation treatment device for municipal solid waste incineration slag. The device includes a primary sedimentation tank connected to a secondary sedimentation tank on one side, a secondary sedimentation tank connected to a tertiary sedimentation tank on the side of the secondary sedimentation tank furthest from the primary sedimentation tank, and a clear water tank connected to the side of the tertiary sedimentation tank furthest from the secondary sedimentation tank. An inlet pipe runs through the top of the primary sedimentation tank on the side furthest from the secondary sedimentation tank, and an outlet pipe runs through the top of the clear water tank. The bottoms of the primary, secondary, and tertiary sedimentation tanks are all connected to slag boxes, and the back bottoms of the primary, secondary, and tertiary sedimentation tanks are all connected to conveyor boxes containing auger conveying mechanisms. The invention also discloses a control method for the wastewater recycling and grading sedimentation treatment device for municipal solid waste incineration slag. By using multiple filters, this invention allows for multiple purifications of the wastewater from slag cleaning, converting it into a recyclable cleaning liquid without requiring prolonged sedimentation and improving wastewater recycling efficiency.

[0004] However, since incinerator slag has a certain temperature, the slag water produced by washing the incinerator slag will carry a certain amount of heat when discharged. In the process of treating the slag water, the heat in the slag water is not recovered and utilized. Based on this, a waste incinerator slag water circulation graded sedimentation treatment device and its control method are proposed. Summary of the Invention

[0016] A control method for a waste incinerator slag water circulation and staged sedimentation treatment device includes the following steps:

[0017] S: The slag water enters the first sedimentation tank through the inlet bend. The slag water passes through the first sedimentation tank, the second sedimentation tank, the third sedimentation tank and the fourth sedimentation tank in sequence, so that the mud or particulate matter of different particle sizes in the slag water is filtered by the filter screen and falls to the bottom of the corresponding sedimentation tank.

[0018] S: Start the exhaust fan to draw the air out of the mounting housing into the fixed frame.

[0020] S: Start the rotating motor to drive the first pulley to rotate, and at the same time drive the second pulley to rotate through the second transmission belt. While the second pulley is rotating, it drives the first transmission belt to rotate through the third pulley. While the first transmission belt is rotating, it drives the fourth pulley to rotate. The rotation of the first pulley, second pulley, third pulley and third pulley drives the first spiral blade, second spiral blade and third spiral blade to rotate at the same time, and transports the mud or particles in the shell to the first sedimentation tank through the slag conveying pipe.

[0021] S: Start the first rotary motor to drive the first gear to rotate repeatedly in both directions. While the first gear is rotating, it drives the second gear to rotate. While the second gear is rotating, it drives the lead screw to rotate, which in turn drives the horizontal plate to move up and down repeatedly. At the same time, the horizontal plate drives the crushing block to move up and down repeatedly, thus crushing the clumps of mud or particles.

[0022] S: Start the second rotary motor to drive the fourth spiral blade to rotate inside the vertical shell. The rotation of the fourth spiral blade transports the mud or particles in the first sedimentation tank to the slag outlet, so that the mud or particles are discharged through the slag outlet to the slag discharge slide for export.

[0023] The beneficial effects of this invention are:

[0024] This invention achieves graded sedimentation treatment of slag water by filtering out mud or particulate matter of different particle sizes in the slag water through a first sedimentation tank, a second sedimentation tank, a third sedimentation tank, and a fourth sedimentation tank, and allowing the sediment to fall to the bottom of the corresponding sedimentation tank.

[0025] This invention recovers heat from slag slurry through a heat recovery mechanism, and draws the heated air into a fixed frame using an exhaust fan. The air is further heated by the cooperation of a rotating fan, a battery, and a heating wire. The heated air dries the mud or particles located on the slag discharge chute, which is beneficial for the recovery and utilization of heat from the slag slurry. The drying of mud or particles is achieved through heat recovery.

[0026] The present invention improves the sedimentation effect of slag water by using a conveying mechanism to transport the mud or particles contained in the outer shell to the first sedimentation tank for re-sedimentation treatment.

[0027] This invention uses a crushing mechanism to break up clumps of mud or particles, which is beneficial for the sedimentation treatment of slag water.

[0028] This invention uses a slag discharge mechanism to transport mud or particles to the slag discharge port, allowing the mud or particles to be discharged through the slag discharge port onto the slag discharge chute for export, which is beneficial for the subsequent collection and use of mud or particles.

A slag discharge slide 10 is fixedly installed on one side of the first sedimentation tank 1, the second sedimentation tank 2, the third sedimentation tank 3 and the fourth sedimentation tank 4. The slag discharge slide 10 is located below the slag outlet 96.

[0054] A control method for a waste incinerator slag water circulation and staged sedimentation treatment device includes the following steps:

[0055] S1: The slag water enters the first sedimentation tank 1 through the inlet bend 5. The slag water passes through the first sedimentation tank 1, the second sedimentation tank 2, the third sedimentation tank 3 and the fourth sedimentation tank 4 in sequence, so that the mud or particulate matter of different particle sizes in the slag water is filtered by the filter screen and falls to the bottom of the corresponding sedimentation tank.

[0056] S2: Start the exhaust fan 62 to draw the air out of the mounting housing 61 into the fixed frame 63. When the air is drawn out into the fixed frame 63, it applies a force to the rotating fan 65, causing the rotating fan 65 to rotate. While the rotating fan 65 is rotating, the generator 64 converts the kinetic energy into electrical energy and stores it in the battery 67. The battery 67 supplies power to the heating wire 68 to heat it. The heating wire 68 further heats the air passing through it. The heated air is delivered to the air supply housing 610 through the air supply pipe 69 and then discharged through the air outlet 611.

[0057] S3: After the slag water is filtered by the second guide plate 14, the mud or particles that do not meet the requirements are collected in the container shell 71 through the second guide plate 14 and the transmission pipe 11.

[0058] S4: Start the rotating motor 72 to drive the first pulley 78 to rotate, and at the same time drive the second pulley 79 to rotate through the second transmission belt 713. While the second pulley 79 is rotating, it drives the first transmission belt 712 to rotate through the third pulley 710. While the first transmission belt 712 is rotating, it drives the fourth pulley 711 to rotate at the same time. The rotation of the first pulley 78, the second pulley 79, the third pulley 710 and the third pulley 710 drive the first spiral blade 74, the second spiral blade 75 and the third spiral blade 76 to rotate at the same time, and transport the mud or particles in the shell 71 to the first sedimentation tank 1 through the slag conveying pipe 12.

[0059] S5: Start the first rotary motor 82 to drive the first gear 84 to rotate repeatedly in both directions. While the first gear 84 is rotating, it drives the second gear 85 to rotate. While the second gear 85 is rotating, it drives the lead screw 88 to rotate, which in turn drives the horizontal plate 89 to move up and down repeatedly. At the same time, the horizontal plate 89 drives the crushing block 810 to move up and down repeatedly, and the crushing block 810 crushes the clumps of mud or particles.

[0060] S6: Start the second rotary motor 92 to drive the fourth spiral blade 94 to rotate inside the vertical shell 91. The rotation of the fourth spiral blade 94 transports the mud or particles in the first sedimentation tank 1 to the slag outlet 96, so that the mud or particles are discharged through the slag outlet 96 to the slag discharge slide 10 for export.

[0061] To ensure the smooth implementation of this solution, it is also necessary to understand that all electrical components mentioned in this document are installed in unused locations within this device and are electrically connected to an external main controller and 220V AC mains power. Furthermore, the main controller can be a conventional, known device such as a computer for control.

[0062] The working principle of this invention is as follows: When the wastewater generated from cleaning incinerator slag is discharged, the slag water carrying a certain amount of heat enters the first sedimentation tank 1 through the inlet bend 5. This allows the mud and sand particles in the slag water to undergo preliminary gravity sedimentation in the first sedimentation tank and fall to the bottom of the first sedimentation tank. The slag water then passes through the first sedimentation tank 1, the second sedimentation tank 2, the third sedimentation tank 3, and the fourth sedimentation tank 4 in sequence. This allows mud or particulate matter of different particle sizes in the slag water to be filtered by the filter screen and fall to the bottom of the corresponding sedimentation tank, thus realizing the circulating and graded sedimentation treatment of waste incinerator slag water.

[0063] When the slag water passes through the mounting shell 61, it exchanges heat with the air inside the mounting shell 61 to a certain extent through the water inlet bend 5, thus heating the air inside the mounting shell 61 to a certain extent. The exhaust fan 62 is started to draw the heated air from the mounting shell 61 into the fixed frame 63. When the air is drawn into the fixed frame 63, it applies a force to the rotating fan 65, causing the rotating fan 65 to rotate. While the rotating fan 65 is rotating, the kinetic energy is converted into electrical energy by the generator 64 and stored in the battery 67. The battery 67 supplies power to the heating wire 68 for heating. The heating wire 68 further heats the air passing through it. The heated air is transported to the air conveying shell 610 through the air supply pipe 69 and then discharged through the air outlet 611 to dry the mud or particles located on the slag discharge slide 10.

[0064] After being filtered by the second guide plate 14, the slag water that does not meet the requirements is filtered through the second guide plate 14 and the transmission pipe 11 and enters the holding shell 71. The first pulley 78 is rotated by the rotating motor 72, and the second pulley 79 is rotated by the second transmission belt 713. The rotation of the second pulley 79 drives the first transmission belt 712 to rotate through the third pulley 710. The rotation of the first transmission belt 712 drives the fourth pulley 711 to rotate at the same time. The rotation of the first pulley 78, the second pulley 79, the third pulley 710 and the third pulley 710 drives the first spiral blade 74, the second spiral blade 75 and the third spiral blade 76 to rotate at the same time. The slag water or particles in the holding shell 71 are transported to the first sedimentation tank 1 through the slag conveying pipe 12 for re-sedimentation treatment, which further improves the sedimentation treatment effect of the slag water.

[0065] The first rotary motor 82 drives the first gear 84 to rotate repeatedly in both directions. While the first gear 84 is rotating, it drives the second gear 85 to rotate. While the second gear 85 is rotating, it drives the lead screw 88 to rotate, which in turn drives the horizontal plate 89 to move up and down repeatedly. At the same time, the horizontal plate 89 drives the crushing block 810 to move up and down repeatedly. The crushing block 810 crushes the clumps of mud or particles, which is beneficial for the sedimentation treatment of slag water.

[0066] The second rotary motor 92 is started to drive the fourth spiral blade 94 to rotate inside the vertical shell 91. The rotation of the fourth spiral blade 94 transports the mud or particles in the first sedimentation tank 1 to the slag outlet 96, so that the mud or particles are discharged through the slag outlet 96 to the slag discharge slide 10 for export, which is beneficial for the later use of the mud or particles.

[0067] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

While the second pulley (79) rotates, it drives the first transmission belt (712) to rotate through the third pulley (710). While the first transmission belt (712) rotates, it drives the fourth pulley (711) to rotate. The rotation of the first pulley (78), the second pulley (79), the third pulley (710) and the third pulley (710) drives the first spiral blade (74), the second spiral blade (75) and the third spiral blade (76) to rotate at the same time, and transport the mud or particles in the shell (71) to the first sedimentation tank (1) through the slag conveying pipe (12). S5: Start the first rotary motor (82) to drive the first gear (84) to rotate repeatedly in both directions. While the first gear (84) is rotating, it drives the second gear (85) to rotate. While the second gear (85) is rotating, it drives the lead screw (88) to rotate, which in turn drives the horizontal plate (89) to move up and down repeatedly. At the same time, the horizontal plate (89) drives the crushing block (810) to move up and down repeatedly, and the crushing block (810) crushes the clumps of mud or particles. S6: Start the second rotary motor (92) to drive the fourth spiral blade (94) to rotate inside the vertical shell (91). The rotation of the fourth spiral blade (94) transports the mud or particles in the first sedimentation tank (1) to the slag outlet (96), so that the mud or particles are discharged through the slag outlet (96) to the slag discharge slide (10) for export.
