Description

Technical Field

[0001] The utility model belongs to the technical field of acid regeneration, and in particular relates to a novel oxide processing system with a dust removal function. Background Art

[0002] The iron oxide balls produced by the acid regeneration reactor pass through a screw conveyor, bucket elevator, and crusher and enter the silo. In the original oxide processing system, the broken iron oxide balls cause unorganized emissions. Not all oxides can be stored in the silo. Long-term accumulation will cause oxide waste, increase the loss of the unit's by-product Fe2O3, reduce the oxide reserves in the silo, and affect the workshop environment, requiring regular cleaning.

[0003] Upon investigation, the disclosure (announcement) number: CN207237627U discloses a device for recovering fine iron oxide powder from a waste pickling acid regeneration system. This technology discloses "a high-efficiency gas-solid separation filter for being arranged between a roasting reactor and a pre-concentrator in the waste pickling acid regeneration system; the filter's to-be-filtered gas input end is used to connect to the furnace gas output end of the roasting reactor, and the filtered gas output end is used to connect to the high-temperature gas input end of the pre-concentrator; the filter's filtering component uses a filter membrane and other technical solutions, and has the function of recovering suspended iron oxide powder with a particle size of less than 1 micron through the filter. These fine iron oxide powders contain a large amount of submicron or even nanometer-sized iron oxide powder and have a high market value. In addition, by recovering the fine iron oxide powder in advance, the amount of iron oxide powder entering the pre-concentrator is greatly reduced, and the reverse reaction of the iron oxide powder with hydrogen chloride to form ferrous chloride and ferric chloride, which then returns to the roasting reactor to participate in the pyrolysis reaction again, is effectively avoided, and other technical effects are achieved."

[0004] The above design can avoid the reverse reaction between iron oxide powder and hydrogen chloride to generate ferrous chloride and ferric chloride, which are then returned to the roasting reactor to participate in the pyrolysis reaction again. However, when the oxides and other impurities in the exhaust gas of the dust collector are filtered, the impurities will adhere to the surface of the filter screen in the dust collector. After long-term use, these impurities will easily clog the mesh of the filter screen, thereby affecting the filtering effect of the filter screen and making it inconvenient to use.

[0005] In order to solve the above problems, this application proposes a new type of oxide processing system with dust removal function. Utility Model Content

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown:

[0028] A novel oxide processing system with dust removal function includes a reactor 1, a screw conveyor 8 fixedly connected to the discharge port of the reactor 1, and a material hoist 5 connected to the side of the screw conveyor 8 away from the reactor 1. The top of the material hoist 5 is connected to a crusher 7 through a connecting pipe. A dust removal box 2 is provided on one side of the crusher 7, and the input end of the dust removal box 2 is respectively connected to the crusher 7 and the material hoist 5 through a smoke outlet pipe 6.

[0029] In this embodiment: the existing disclosure (announcement) number: CN207237627U discloses a device for recovering fine iron oxide powder from a pickling waste acid regeneration system; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although it can avoid the reverse reaction of iron oxide powder with hydrogen chloride to generate ferrous chloride and ferric chloride and return to the roasting reactor 1 to participate in the pyrolysis reaction again, but when filtering impurities such as oxides in the exhaust gas from the dust collector, the impurities will adhere to the surface of the filter screen in the dust collector. After long-term use, these impurities will easily clog the mesh on the surface of the filter screen, thereby affecting the filtering effect of the filter screen and making it inconvenient to use." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a filter component 3 and a spray component 4 are added to this application document.

[0030] It should be noted that the iron oxide balls at the bottom of the reactor 1 enter the screw conveyor 8 through the discharge port at the lower part of the fluidized bed acid regeneration reactor 1, the screw conveyor 8 is connected to the material hoist 5, the material hoist 5 is connected to the crusher 7, and a portion of the iron oxide balls is sent to the crusher 7 through the screw conveyor 8 and the material hoist 5, and the crusher 7 is connected to the dust removal box 2 and the crusher 7 through the smoke outlet pipe 6.

[0031] It should be noted that: when the output of iron oxide balls is normal: if the output value is within the specified range, monitor the start-up time of the crusher 7 and start the dust collector; when the output of iron oxide balls is abnormal: if the output value is lower than or exceeds the specified range, adjust the start-up time of the dust collector based on the monitoring of the operating frequency of the screw conveyor 8 and the material hoist 5, and the start-up time of the crusher 7; when the output of iron oxide balls returns to normal: monitor the operating frequency of the screw conveyor 8 and the material hoist 5, and the start-up time of the crusher 7, determine that the data is normal, and the operating frequency of the dust collector returns to the normal specified frequency, and starts following the start-up of the crusher 7.

[0032] like Figure 1-Figure 4 As shown:

[0033] More specifically:

[0034] In combination with the above content, the filter assembly 3 includes a filter plate 311 fixedly connected to the inside of the dust removal box 2, a cleaning plate 39 symmetrically arranged on the surface of the filter plate 311, and a slider 310 fixedly connected between the two groups of cleaning plates 39.

[0035] In this embodiment: when the device is in use, the filter plate 311 can filter the oxide impurities in the exhaust gas passing through the dust removal box 2. When used for a long time, the filtered impurities will accumulate on the surface of the filter plate 311. When it is necessary to clean the impurities on the surface of the filter plate 311, the cleaning plate 39 is driven to move back and forth on the surface of the filter plate 311, so that the slider 310 slides inside the slide groove 312 to clean the impurities on the surface of the filter plate 311 to prevent them from clogging the filter plate 311 and affecting the filtering effect of the device.

[0036] It should be noted that the slider 310 slides inside the slide groove 312, which can increase the stability of the movement of the two sets of cleaning plates 39. A brush is provided on the side of the cleaning plate 39 close to the filter plate 311, so that the cleaning plate 39 can move to clean impurities on the surface of the filter plate 311.

[0037] Going further:

[0038] In combination with the above content, a slide groove 312 is provided on the side of the dust collection box 2 near the slider 310, and the slider 310 and the dust collection box 2 are slidably connected through the slide groove 312. The top of the dust collection box 2 is fixedly connected to the side of the filter plate 311, and the output end of the motor 31 is fixedly connected to the cam 35. The surface of the cam 35 is fixedly connected to the runner 37. The surface of the cleaning plate 39 is fixedly connected to the connecting rod 38. The end of the connecting rod 38 away from the cleaning plate 39 passes through the interior of the dust collection box 2 and is fixedly connected to the frame plate 36 provided on the upper side of the dust collection box 2, and the runner 37 is located inside the frame plate 36. The bottom end of the dust collection box 2 is fixedly connected to the side of the filter plate 311. The surface of the collecting box 32 is hinged with a cleaning door through a hinge. The exhaust port of the dust collection box 2 is fixedly connected to the exhaust pipe 33. Activated carbon adsorption plates 34 are symmetrically installed on one side of the dust collection box 2 near the exhaust pipe 33.

[0039] In this embodiment, when the device is in use, the filter plate 311 can filter the oxide impurities in the exhaust gas passing through the dust removal box 2. When used for a long time, the filtered impurities will accumulate on the surface of the filter plate 311. When it is necessary to clean the impurities on the surface of the filter plate 311, first start the motor 31 to drive the cam 35 to rotate. The rotation of the cam 35 will drive the wheel 37 to slide inside the frame plate 36. As the wheel 37 makes a circular motion, it will drive the frame plate 36 to move back and forth vertically, and then drive the two sets of cleaning plates 39 on the surface of the filter plate 311 through the connecting rod 38. The surface moves back and forth, causing the slider 310 to slide inside the slide groove 312, cleaning the impurities on the surface of the filter plate 311, and then the impurities will fall into the collection box 32 and be collected, so that the impurities on the surface of the filter plate 311 can be automatically cleaned to avoid clogging the filter plate 311 and affecting the filtering effect of the device. At the same time, the oxides are collected by the collection box 32 to improve the utilization rate of the oxides. Subsequently, the activated carbon adsorption plate 34 further adsorbs the harmful substances in the exhaust gas, and the fully purified exhaust gas is discharged through the exhaust pipe 33.

[0040] It should be noted that the cleaning door on the collection box 32 facilitates the removal of oxides inside the collection box 32, thereby reducing the loss of oxides.

[0041] It should be noted that the activated carbon adsorption plate 34 can be detachably installed inside the dust removal box 2, so that the activated carbon adsorption plate 34 can be easily cleaned or replaced.

[0042] It should be noted that a filter is provided inside the exhaust pipe 33 to prevent external dust and impurities from entering the dust removal box 2 through the exhaust pipe 33 .

[0043] Going further:

[0044] In combination with the above content, a spray assembly 4 is provided inside the dust removal box 2, and the spray assembly 4 includes several groups of atomizing nozzles 44 installed inside the dust removal box 2, and a treatment liquid storage box 42 fixedly connected to the top of the dust removal box 2 and a water pump 43 fixedly connected to the top of the dust removal box 2 close to the side of the treatment liquid storage box 42, and the output end and input end of the water pump 43 are respectively connected to the atomizing nozzle 44 and the treatment liquid storage box 42 through connecting pipes, and the bottom end of the dust removal box 2 is fixedly connected to a waste liquid collection box 41, and the inside of the dust removal box 2 is fixedly connected to a water baffle 45 close to the side of the atomizing nozzle 44.

[0045] In this embodiment: after the filter plate 311 filters the exhaust gas, the water pump 43 is started, and the treatment liquid inside the treatment liquid storage box 42 is pumped out by the water pump 43, and then sprayed out through the atomizing nozzle 44 to form water mist, which reacts with the harmful substances in the exhaust gas. Then the waste liquid collection box 41 collects the waste liquid after the reaction, thereby reducing the air pollution caused by the exhaust gas emission.

[0046] It should be noted that the motor 31 and the water pump 43 are both electrically connected to an external power source via wires.

[0047] It should be noted that the water blocking plate 45 can block the water mist sprayed by the atomizing nozzle 44 .

[0048] Working principle: When the device is in use, the filter plate 311 can filter the oxide impurities in the exhaust gas passing through the dust removal box 2. When used for a long time, the filtered impurities will accumulate on the surface of the filter plate 311. When the impurities on the surface of the filter plate 311 need to be cleaned, the motor 31 is first started to drive the cam 35 to rotate. The rotation of the cam 35 will drive the wheel 37 to slide inside the frame plate 36. As the wheel 37 makes a circular motion, it will drive the frame plate 36 to move back and forth vertically, and then drive the two sets of cleaning plates 39 to move back and forth on the surface of the filter plate 311 through the connecting rod 38, so that the slider 310 slides inside the slide groove 312 to clean the impurities on the surface of the filter plate 311, and then the impurities will fall into the collection box 32. Impurities are collected, so that the impurities on the surface of the filter plate 311 can be automatically cleaned to avoid clogging the filter plate 311 and affecting the filtering effect of the device. At the same time, the oxides are collected through the collection box 32 to improve the utilization rate of the oxides. After the filter plate 311 filters the exhaust gas, the water pump 43 is started, and the treatment liquid inside the treatment liquid storage box 42 is extracted through the water pump 43, and then sprayed out through the atomizing nozzle 44 to form water mist, which reacts with the harmful substances in the exhaust gas. Then the waste liquid collection box 41 collects the waste liquid after the reaction, and then the activated carbon adsorption plate 34 further adsorbs the harmful substances in the exhaust gas. The fully purified exhaust gas is discharged through the exhaust pipe 33, thereby reducing the air pollution caused by exhaust gas emissions.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
