Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and specifically relates to a desulfurized wastewater sludge treatment system. Background Art

[0002] Desulfurization generally refers to the process of removing sulfur from fuel before combustion and desulfurizing flue gas before emission. After desulfurization, residues such as sludge and wastewater will be formed. The main components of desulfurized sludge include ash, gypsum, chloride ions, heavy metals, etc.; These substances will act together to block the channels of free water between crystals among gypsum crystals, and then distort the gypsum lattice, generating more crystal nuclei, resulting in the characteristics of high moisture content, high viscosity, and large volume of desulfurized sludge. Existing sludge dewatering machines only circulate once inside the clarification tank and sludge dewatering devices such as spiral press and belt filter press, and only separate the water content of the sludge, without further filtering and distinguishing the impurities in the sewage, resulting in poor treatment effects. Moreover, the sludge will agglomerate after dewatering. During the feeding and transportation process, when irregularly shaped solid blocks are transported on the conveyor belt, their center of gravity is unstable, and the sludge may fall off the conveyor belt.

The telescopic end of the first hydraulic rod is fixedly connected to a push plate. A water pump is fixedly installed on the right side of the housing. A first connecting pipe is fixedly connected to the front side of the water pump, and a water suction pipe is fixedly connected to the top of the water pump.

[0006] Preferably, the push plate is movably installed in the housing at an inclined angle, and the first connecting pipe is fixedly connected to the side surface of the circular housing.

[0007] Preferably, the isolation component includes a frame fixedly installed inside the housing. A plurality of rotating plates are movably hinged inside the frame. The right rotating shafts of the plurality of rotating plates are all movably hinged to connecting bars. The bottoms of the plurality of connecting bars are movably hinged to a track, and the right end of the track is fixedly connected to a second hydraulic rod.

[0008] Preferably, the pyrolysis component includes a first motor fixedly installed on the right side of the housing. The output shaft of the first motor is connected to a screw rod. The screw rod penetrates and is installed inside the housing. A heating shell is sleeved on the outer edge of the middle part of the screw rod on the right side. Three collecting pipes are fixedly connected to the top of the heating shell. The tops of the three collecting pipes are connected to a second connecting pipe, and the second connecting pipe is fixedly connected to the side surface of the circular housing.

[0009] Preferably, the crushing component includes multiple support rods fixedly installed on both sides of the crawler. A hopper is fixedly installed on the tops of the multiple support rods. Two knife rollers are rotatably installed inside the hopper. First gears are fixedly connected to the left sides of the two knife rollers. A second gear meshes with the middle positions of the two first gears, and a second motor is fixedly connected to the left side of the second gear.

[0010] Preferably, the storage component includes an oil storage tank fixedly installed on the top of the tabletop. A third connecting pipe is fixedly connected to the top of the oil storage tank. The third connecting pipe is fixedly connected to the top of the circular housing. A water storage tank is fixedly installed on the front side of the oil storage tank. A square pipe is fixedly connected to the back of the water storage tank, and the square pipe is fixedly connected to the front side of the collecting dish.

[0011] The beneficial effects of the present invention are as follows: 1. In the present invention, by installing a newly designed filtering component, the oil-water mixture will accumulate from bottom to top within the circular shell. Water will gradually move towards the bottom layer of the liquid, while oil will move downwards. The oil and water will continuously pass through the coarse filter element and the fine filter element in the lower layer for two-stage filtration. Eventually, the entire liquid surface will achieve a state where oil is on top and water is at the bottom. The barrier net at the top is longitudinally stacked by multiple corrugated metal plates, forming multiple corrugated bending channels. Water will encounter an upward resistance here, and due to the smooth metal plates, it is difficult for water droplets to adhere, preventing the situation where water is accidentally discharged when the liquid surface rises rapidly and water is squeezed here. This solves the problem of the existing sludge dewatering machine that only operates in a single cycle, only separates the water from the sludge, and cannot further filter and distinguish the impurities in the sewage.

[0012] 2. In the present invention, by installing a separating component, the connecting bar increases its stroke, thereby pushing the track to move towards the left, and enabling the connecting bar hinged within the track to rotate by a certain angle, driving multiple rotating plates to rotate clockwise and close within the frame. The sludge and heavier substances are separated in the lower layer formed by the isolation component and the housing, while the wastewater is isolated in the upper layer of the isolation component, thus realizing a separated clarifying tank. When extracting the wastewater in the upper layer, due to the fluidity of water, impurities will not be re-absorbed.

[0013] 3. In the present invention, by installing a crushing device, starting the second motor drives the second gear to rotate, and then the first gears on both sides rotate in opposite directions, driving the two knife rollers in the hopper to rotate symmetrically, crushing and loosening the solidified sludge. The crushed soil falls onto the track and is transported by the track, solving the problem that the sludge will form lumps after dewatering. During the feeding and transportation process, when the irregularly shaped solid blocks are transported on the track, their center of gravity is unstable, which may cause them to fall off.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figures 1 to 10 shown, the embodiment of the present invention provides a desulfurized wastewater sludge treatment system, including a base 1. The base 1 includes a tabletop 11. A crawler 12 is fixedly installed on the left side of the tabletop 11. A clarification component 2 is fixedly installed on the upper right side of the tabletop 11. It further includes a linkage wastewater sludge treatment mechanism, which includes an isolation component 3. The isolation component 3 is fixedly installed inside the clarification component 2. A pyrolysis component 4 is fixedly installed on the left side of the clarification component 2. A crushing component 5 is fixedly installed on the left side of the pyrolysis component 4. A storage component 7 is fixedly installed on the front side of the pyrolysis component 4; A filtration component 6, the filtration component 6 includes a round shell 61. The bottom of the round shell 61 is fixedly connected to a collection dish 62. The collection dish 62 is fixedly installed on the top of the tabletop 11. A support 63 is fixedly installed on the top of the collection dish 62. A plurality of coarse filter elements 64 are fixedly installed on the top of the support 63. The tops of the plurality of coarse filter elements 64 are fixedly connected to fine filter elements 65. A barrier net 66 is fixedly installed at the bottom of the plurality of fine filter elements 65. The barrier net 66 is formed by longitudinally stacking a plurality of corrugated metal plates; Oil and water will accumulate from bottom to top in the cavity formed by the round shell 61 and the collection dish 62 due to gravity. Since water has a greater specific heat capacity than oil, it will gradually move to the bottom of the liquid, while oil has a smaller specific heat capacity, so the oil on the top will also move upward. Oil and water will continuously pass through the coarse filter element 64 and the fine filter element 65 at the lower layer for double filtration, and finally the entire liquid surface is achieved with oil on top and water on the bottom. The oil enters the water storage tank 73 through the third connecting pipe 72 at the top of the collection dish 62, while the water enters the water storage tank 73 through the square pipe 74. The work process ends here. The barrier net 66 on the top is composed of multiple corrugated metal plates stacked longitudinally to form multiple corrugated curved channels. Water will encounter rising resistance here, and the smooth metal plates make it difficult for water droplets to adhere to, preventing the liquid surface from rising rapidly and being squeezed here and accidentally discharged. This solves the problem that the existing sludge dewatering machine only uses a clarification tank and desludging devices such as spiral stacking and belt dewatering machines, and only cycles once, only analyzing the water in the sludge, but cannot further filter and distinguish the impurities in the sewage.

[0018] The clarification component 2 includes a shell 21, which is fixedly mounted on the top of the table 11. A first hydraulic rod 22 is fixedly connected to the right side of the inside of the shell 21, and a push plate 23 is fixedly connected to the telescopic end of the first hydraulic rod 22. A water pump 24 is fixedly mounted on the right side of the shell 21, and a first connecting pipe 25 is fixedly connected to the front side of the water pump 24. A water suction pipe 26 is fixedly connected to the top of the water pump 24. The push plate 23 is movably mounted in the shell 21 at an inclined angle, and the first connecting pipe 25 is fixedly connected to the side of the round shell 61. The mixture of wastewater and sludge is poured into the clarification component 2. The heavier debris in the sludge and sewage can gradually sink to the bottom of the shell 21 due to gravity. The stroke of the first hydraulic rod 22 is increased, which can drive the push plate 23 to push in the shell 21 toward the pyrolysis component 4. At this time, the sludge can contact the spiral rod 42. The isolation assembly 3 includes a frame 31, which is fixedly installed inside the housing 21. A plurality of rotating plates 32 are movably hinged on the inner side of the frame 31. The right rotation axes of the plurality of rotating plates 32 are all movably hinged with connecting bars 33. The bottoms of the plurality of connecting bars 33 are movably hinged with tracks 34. The right end of the track 34 is fixedly connected with a second hydraulic rod 35. The connecting strip 33 increases the stroke, thereby pushing the track 34 to move to the left, and enables the connecting strip 33 hinged in the track 34 to rotate a certain angle, thereby driving the multiple rotating plates 32 to rotate clockwise and close in the frame 31, separating the sludge and heavier substances in the lower layer formed by the isolation component 3 and the shell 21, while the wastewater is isolated in the upper layer of the isolation component 3, thereby realizing a separated clarification tank. When the wastewater in the upper layer is extracted, the impurities will not be reabsorbed due to the fluidity of the water; Among them, the pyrolysis component 4 includes a first motor 41, the first motor 41 is fixedly installed on the right side of the housing 21, the output shaft of the first motor 41 is connected to a screw rod 42, the screw rod 42 penetrates and installs inside the housing 21, and a heating shell 43 is sleeved on the outer edge of the middle part of the screw rod 42 on the right side. Three collecting pipes 44 are fixedly connected to the top of the heating shell 43, and the tops of the three collecting pipes 44 are connected to a second connecting pipe 45, and the second connecting pipe 45 is fixedly connected to the side surface of the circular shell 61; By starting the first motor 41, the screw rod 42 is driven to rotate clockwise, and all the sludge in the lower layer of the housing 21 is transported into the heating shell 43. At this time, the heating shell 43 is heated, and the water and the oily substance containing heavy metals in the sludge are evaporated upward together. After being collected by the three collecting pipes 44, they enter the filtering component 6 through the second connecting pipe 45, while the solidified sludge is continuously transported by the screw rod 42 into the crushing component 5; Among them, the crushing component 5 includes multiple support rods 51, the multiple support rods 51 are fixedly installed on both sides of the crawler 12, a hopper 52 is fixedly installed on the top of the multiple support rods 51, and two cutter rollers 53 are rotatably installed inside the hopper 52. A first gear 54 is fixedly connected to the left side of the two cutter rollers 53, and a second gear 55 is engaged at the middle position of the two first gears 54, and a second motor 56 is fixedly connected to the left side of the second gear 55; By starting the second motor 56 to drive the second gear 55 to rotate, the first gears 54 on both sides can rotate in opposite directions, driving the two cutter rollers 53 in the hopper 52 to rotate symmetrically, crushing and loosening the solidified sludge. The crushed soil falls onto the crawler 12 and is transported by the crawler 12, solving the problem that the sludge will agglomerate after dehydration. During the feeding and transportation process, when the irregularly shaped solid is transported on the crawler, its center of gravity is unstable and may cause it to fall off; Among them, the storage component 7 includes an oil storage tank 71, the oil storage tank 71 is fixedly installed on the top of the table 11, a third connecting pipe 72 is fixedly connected to the top of the oil storage tank 71, the third connecting pipe 72 is fixedly connected to the top of the circular shell 61, a water storage tank 73 is fixedly installed on the front side of the oil storage tank 71, and a square pipe 74 is fixedly connected to the back of the water storage tank 73, and the square pipe 74 is fixedly connected to the front side of the collecting dish 62; The oil enters the water storage tank 73 through the third connecting pipe 72 at the top of the collecting dish 62 for storage, and the water enters the water storage tank 73 through the square pipe 74 for storage.

[0019] Working principle: When using the present invention to dehydrate wastewater sludge, first, the mixture of wastewater and sludge is poured into the clarification component 2. Heavier impurities in the sludge and sewage gradually sink to the bottom inside the housing 21 due to gravity. At this time, the isolation component 3 is started, the connecting bar 33 increases its stroke, thereby pushing the track 34 to move to the left, and enabling the connecting bar 33 hinged inside the track 34 to rotate by a certain angle, thus driving a plurality of rotating vanes 32 to rotate clockwise and close inside the frame 31, separating the sludge and heavier substances in the lower layer formed by the isolation component 3 and the housing 21, while the wastewater is isolated in the upper layer of the isolation component 3. At this time, through the water suction pipe 26, it is pumped by the water pump 24 and enters the filtration component 6 through the first connecting pipe 25. When extracting the upper-layer wastewater in the separated sedimentation tank, impurities will not be sucked again due to the fluidity of water; At this time, the first hydraulic rod 22 increases its stroke, driving the push plate 23 to push towards the pyrolysis component 4 inside the housing 21. At this time, all the sludge comes into contact with the screw rod 42. The first motor 41 is started to drive the screw rod 42 to rotate clockwise, transporting all the sludge in the lower layer of the housing 21 into the heating shell 43. At this time, the heating shell 43 is heated, and the water and the oil containing heavy metals in the sludge are evaporated upward together. After being collected by the three collecting pipes 44, they enter the filtration component 6 through the second connecting pipe 45, while the solidified sludge is continuously transported by the screw rod 42 into the crushing component 5; When the solidified sludge enters the hopper 52, the second motor 56 is started to drive the second gear 55 to rotate, and then the two first gears 54 on both sides rotate in the reverse direction, driving the two cutter rollers 53 in the hopper 52 to rotate symmetrically, crushing and loosening the solidified sludge. The crushed soil falls onto the crawler 12 and is transported by the crawler 12; The wastewater pumped by the water pump 24 and the water and the oil containing heavy metals collected by the pyrolysis component 4 are all transported into the filtration component 6. These oil and water will accumulate from bottom to top in the cavity formed by the circular shell 61 and the collecting dish 62. Since the specific heat capacity of water is greater than that of oil, water will gradually move to the bottom layer of the liquid, while the specific heat capacity of oil is small, and the oil on the top layer will also move upward. The oil and water will continuously pass through the two-layer filtration between the coarse filter element 64 and the fine filter element 65 at the lower layer, finally achieving the state where oil is on the top and water is on the bottom on the entire liquid surface. The oil enters the water storage tank 73 through the third connecting pipe 72 at the top of the collecting dish 62, and the water enters the water storage tank 73 through the square pipe 74. Thus, the working process ends. The barrier net 66 at the top is longitudinally stacked by multiple corrugated metal plates, forming multiple corrugated bending channels, which can prevent the unexpected situation where the water level rises rapidly, the water is squeezed here, and then discharged into the oil storage tank 71. Thus, the working process ends.
