Description

Technical Field

[0001] The utility model relates to the technical field of wet coke quenching, in particular to a dust collector for a coke quenching tower. Background Art

[0002] In order to reduce pollution emissions, a coke quenching tower is usually set up to treat the coke quenching tail gas. In the wet coke quenching process of the coke quenching tower, cooling water is sprayed onto the high-temperature red coke, and a large amount of steam will be generated instantly. A large amount of waste materials (dust and chemical harmful substances) are carried in the steam and enter the atmosphere in the form of waste gas, thus causing environmental pollution.

[0003] The existing dust removal devices for coke quenching towers can remove dust from the above-mentioned waste gas, but the dust removal effect is poor; and after long-term use, the dust removal devices will be attached with waste materials by themselves, but it is very difficult to disassemble them for cleaning, which further affects their dust removal effect. Therefore, there is an urgent need for a dust collector for a coke quenching tower to solve the above problems. Summary of the Utility Model

[0004] In order to solve the technical problems of poor dust removal effect of the existing dust removal device for a coke quenching tower and difficulty in disassembling and cleaning itself, the utility model provides a dust collector for a coke quenching tower. Multiple high-pressure nozzles are used to remove dust from the waste gas, and the dust removal efficiency is higher; after the high-pressure nozzles are used for a certain period of time, they can be disassembled for cleaning to avoid waste materials attaching to the high-pressure nozzles and affecting their dust removal effect.

[0005] The utility model provides a dust collector for a coke quenching tower, which comprises a dust removal box arranged above the coke quenching tower and communicated with the inside of the coke quenching tower. An exhaust port is arranged on the dust removal box. The dust collector for the coke quenching tower further comprises a dust removal component, which comprises an annular support frame and multiple high-pressure nozzles. The annular support frame is movably arranged in the dust removal box and located below the exhaust port. Multiple connecting plates are evenly and detachably arranged on the annular support frame. Multiple high-pressure nozzles are respectively arranged on the multiple connecting plates. A protective cover is arranged in the dust removal box. The annular support frame and the multiple connecting plates are both located inside the protective cover. An operation port and an opening are sequentially arranged on the protective cover. The operation port is located at the top of the protective cover, and the opening is located at the side of the protective cover. One ends of the multiple high-pressure nozzles are located inside the protective cover, and the other ends pass through the opening to the outside of the protective cover. Multiple high-pressure nozzles operate to perform dust removal spraying on the waste gas, and then the gas after dust removal finally discharges from the exhaust port. People can manually operate at the operation port to separate the connecting plates from the annular support frame, so that the connecting plates and the high-pressure nozzles can be taken out of the protective cover at the opening, thereby realizing the disassembly of the high-pressure nozzles. Finally, the high-pressure nozzles are taken out from the exhaust port, and people can clean the high-pressure nozzles.

[0006] Further, a plurality of clamping plates are evenly arranged on the annular support frame and are located below the operation port. Each clamping plate includes a first fixed plate and a second fixed plate rotatably arranged on the annular support frame. The first fixed plate and the second fixed plate face each other and are inclined. One end of the first fixed plate and the second fixed plate is connected by a spring, and the other ends are in contact. One end of the connecting plate is clamped between the first fixed plate and the second fixed plate away from the spring, and the other end of the connecting plate is fixedly connected to the high-pressure nozzle. When a person squeezes and approaches one end of the first fixed plate and the second fixed plate connected with the spring, the connecting plate can be taken out from between the first fixed plate and the second fixed plate away from the spring. When the person releases one end of the first fixed plate and the second fixed plate connected with the spring, at this time, under the action of the spring, the other ends of the first fixed plate and the second fixed plate fix the connecting plate.

[0007] Further, each clamping plate further includes a base arranged on the annular support frame. The first fixed plate and the second fixed plate are rotatably arranged on the base and are inclined. Two bearing seats are arranged on the base. Shaft rods are arranged on the sides of the first fixed plate and the second fixed plate. Each shaft rod is rotatably connected to the bearing seat. The shaft rod rotates in the bearing seat, and finally the first fixed plate and the second fixed plate rotate on the base.

[0008] Further, the dust removal assembly further includes a filter plate. The filter plate includes a frame body and a filter screen. The frame body is arranged in the dust removal box and is located below the plurality of high-pressure nozzles. The filter screen is fixedly connected to the frame body. The waste gas generated by the operation of the coke quenching tower dust collector is discharged only after being dust-removed by the dust removal box. First, the waste gas drifts upward to the filter screen, and the filter screen preliminarily filters the waste gas. Then, the plurality of high-pressure nozzles operate to perform dust-removing spraying on the waste gas.

[0009] Further, a cylinder and a slide rail located below the exhaust port are arranged in the dust removal box. A slider is slidably arranged on the slide rail. The telescopic rod of the cylinder is fixedly connected to the slider and can drive the slider to slide on the slide rail. The slider is fixedly connected to the annular support frame. When the cylinder is started, it drives the slider to slide on the slide rail, and further drives the annular support frame fixedly connected to the slider to move up or down.

[0010] Further, a concentration detector is arranged on the dust removal box, and the concentration detector is located at the exhaust port. The gas after dust removal finally discharges from the exhaust port, and the concentration detector can detect the content of dust or / and chemical harmful substances carried by the gas.

[0011] Compared with the prior art, the utility model has the following technical effects:

[0012] Multiple high-pressure nozzles operate to perform dust removal spraying on the waste gas, and then the gas after dust removal finally discharges from the exhaust port; multiple high-pressure nozzles distributed in a ring perform dust removal on the waste gas, with higher dust removal efficiency. People can manually operate at the operation port to separate the connecting plate and the annular support frame, so that the connecting plate and the high-pressure nozzles can be taken out from the protective cover at the opening, thus realizing the disassembly of the high-pressure nozzles. Finally, the high-pressure nozzles are taken out from the exhaust port, and people can clean the high-pressure nozzles. After the high-pressure nozzles are used for a certain period of time, they can be disassembled for cleaning to prevent waste from adhering to the high-pressure nozzles and affecting their dust removal effect.

[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] As Figures 1 to 4As shown in the figure, a coke quenching tower dust collector includes a dust removal box 2 disposed above the coke quenching tower 1 and communicating with the inside of the coke quenching tower 1. An exhaust port is provided on the dust removal box 2. The coke quenching tower dust collector further includes a dust removal assembly. The dust removal assembly includes an annular support frame 21 and a plurality of high-pressure nozzles 22. The annular support frame 21 is movably disposed in the dust removal box 2 and located below the exhaust port. A plurality of connecting plates 23 are detachably disposed on the annular support frame 21 at equal intervals. The plurality of high-pressure nozzles 22 are respectively disposed on the plurality of connecting plates 23, and the plurality of high-pressure nozzles 22 are annularly distributed. A protective cover 3 is disposed in the dust removal box 2, and the annular support frame 21 and the plurality of connecting plates 23 are both located inside the protective cover 3. The protective cover 3 includes a cylinder disposed in the dust removal box 2 and a top plate and a bottom plate respectively disposed outside the top and bottom of the cylinder. The top plate and the bottom plate are fixedly connected in the dust removal box 2. An operation port 31 is provided on the top plate, and an opening 32 is provided on the cylinder. One end of each of the plurality of high-pressure nozzles 22 is located inside the protective cover 3, and the other end passes through the opening 32 to the outside of the protective cover 3. Usually, one end of the high-pressure nozzle 22 is externally connected to a water-cooled hose, and the water-cooled hose is also located inside the protective cover 3 and is supported by the protective cover 3. Among them, the annular support frame 21 and the plurality of connecting plates 23 are both located inside the cylinder, and one end of each of the plurality of high-pressure nozzles 22 is located inside the cylinder, and the other end passes through the opening 32 to the outside of the cylinder.

[0024] The waste gas generated during the operation of the coke quenching tower dust collector is discharged from the exhaust port only after being dust-removed by the dust removal box 2. First, when the waste gas drifts upward through the spaces between the plurality of high-pressure nozzles 22 (i.e., outside the protective cover 3), the plurality of high-pressure nozzles 22 operate to perform dust-removing spraying on the waste gas. Then, the dust-removed gas finally discharges from the exhaust port. The operation mode of the plurality of high-pressure nozzles 22 has a wider treatment range for the waste gas, higher dust-removing efficiency, and better dust-removing effect.

[0025] The protective cover 3 protects the annular support frame 21 and the plurality of connecting plates 23 from waste materials adhering to them. After long-term use, it is inevitable that waste materials will adhere to the other end of the high-pressure nozzle 22 located outside the protective cover 3, which is likely to cause the spray orifice of the high-pressure nozzle 22 to become smaller. At this time, the annular support frame 21 slides upward to a position close to the exhaust port, and a person can manually operate at the operation port 31 to separate the connecting plate 23 from the annular support frame 21, so that the connecting plate 23 and the high-pressure nozzle 22 can be taken out of the protective cover 3 at the opening 32, thereby realizing the disassembly of the high-pressure nozzle 22. Finally, the high-pressure nozzle 22 is taken out from the exhaust port, and a person can clean the high-pressure nozzle 22. Similarly, when one end of the connecting plate 23 and the high-pressure nozzle 22 is fixed back inside the protective cover 3, a person can manually operate at the operation port 31 to reinstall the connecting plate 23 on the annular support frame 21 again, thereby realizing the installation of the high-pressure nozzle 22 on the annular support frame 21. The annular support frame 21 then slides downward to a position away from the exhaust port, and the high-pressure nozzle 22 waits here for dust-removing spraying.

[0026] For the coke quenching tower dust collector of this embodiment, multiple high-pressure nozzles 22 distributed in a ring shape are used to dust the waste gas, and the dust removal efficiency is higher. Moreover, after the high-pressure nozzles 22 are used for a certain period of time, they can be disassembled and cleaned to prevent waste materials from adhering to the high-pressure nozzles 22 and affecting their dust removal effect.

[0027] As an implementable manner, a plurality of clamping plates are evenly arranged on the annular support frame 21 and located below the operation port 31. Each clamping plate includes a first fixed plate 211 and a second fixed plate 214 rotatably arranged on the annular support frame 21. The first fixed plate 211 and the second fixed plate 214 face each other and are in an inclined state. One end of the first fixed plate 211 and the second fixed plate 214 is connected by a spring 213, and the other ends are in contact. One end of the connecting plate 23 is clamped between the first fixed plate 211 and the second fixed plate 214 away from the spring 213, and the other end of the connecting plate 23 is fixedly connected to the high-pressure nozzle 22. When a person squeezes one end of the first fixed plate 211 and the second fixed plate 214 connected with the spring 213 and makes the two approach each other, at this time, the connecting plate 23 can move out from one end of the first fixed plate 211 and the second fixed plate 214 away from the spring 213. On the contrary, when the person releases one end of the first fixed plate 211 and the second fixed plate 214 connected with the spring 213, at this time, under the action of the spring 213, the other ends of the first fixed plate 211 and the second fixed plate 214 clamp and fix the connecting plate 23 by relying on the spring 213.

[0028] As an implementable manner, each clamping plate further includes a base 212 arranged on the annular support frame 21. The first fixed plate 211 and the second fixed plate 214 are rotatably arranged on the base 212 and are in an inclined state. Two bearing seats are arranged on the base 212. Shaft rods are arranged on the sides of the first fixed plate 211 and the second fixed plate 214, and each shaft rod is rotatably connected to the bearing seat. The rotational connection mode of the shaft rod and the bearing seat is a prior art and will not be elaborated here. The shaft rod rotates in the bearing seat, and finally, the first fixed plate 211 and the second fixed plate 214 rotate on the base 212.

[0029] As an implementable mode, the dust removal assembly further includes a filter plate 24, which includes a frame body and a filter screen. The frame body is arranged in the dust removal box 2 and below a plurality of high-pressure nozzles 22, and the filter screen is fixedly connected to the frame body. The waste gas generated during the operation of the coke quenching tower dust collector is discharged only after being dust-removed through the dust removal box 2. First, the waste gas drifts upward to the filter screen, and the filter screen preliminarily filters the waste gas. Then, a plurality of high-pressure nozzles 22 operate to perform dust-removing spraying on the waste gas. After long-term use, the filter screen will absorb a lot of waste materials, and the filtering performance of the filter screen may deteriorate. The water after the waste gas is dust-removed by the operation of a plurality of high-pressure nozzles 22 will pass through the filter screen to the bottom of the coke quenching tower 1, and this water will play a role in cleaning the filter screen so that the filter screen can be used for a long time.

[0030] As an implementable mode, a cylinder 4 and a slide rail 5 located below the exhaust port are arranged in the dust removal box 2. A slider 51 is slidably arranged on the slide rail 5. The telescopic rod of the cylinder 4 is fixedly connected to the slider 51 and can drive it to slide on the slide rail 5. The slider 51 is fixedly connected to the annular support frame 21. When the cylinder 4 is started, it drives the slider 51 to slide on the slide rail 5, and then drives the annular support frame 21 fixedly connected to the slider 51 to move upward or downward. In this embodiment, there are two slide rails 5. The two sliders 51 are fixedly connected to the telescopic rod of the cylinder 4 through a synchronous plate, and the ends of the two sliders 51 are both fixedly connected to the annular support frame 21, making the annular support frame 21 move more stably.

[0031] As an implementable mode, a concentration detector is arranged on the dust removal box 2, and the concentration detector is located at the exhaust port. The gas after dust removal finally discharges from the exhaust port, and the concentration detector can detect the content of dust or / and chemical harmful substances carried by the gas.

[0032] The above-described embodiments are only the preferred embodiments of the present invention, which are only used to explain the present invention and do not limit the scope of implementation of the present invention. For those skilled in the art of this technology, of course, other implementation modes can be easily made according to the technical content disclosed in this specification by means of replacement or change. Therefore, all changes and improvements made in the principles and process conditions of the present invention should be included within the scope of the patent application of the present invention.
