Description

Technical Field

[0001] The utility model belongs to the technical field of dry coke quenching waste heat power generation, and in particular relates to a connecting pipeline for dry coke quenching waste heat power generation. Background Art

[0002] In the process of CDQ waste heat power generation, red coke directly exchanges heat with inert gas, resulting in heat transfer. The temperature of red coke is relatively high, usually above 1000°C, and inert gas (such as nitrogen) is used to absorb this heat. In the process of heat transfer, the temperature of the inert gas will rise, thereby generating heat, which is then recycled and reused, for example, converted into steam through waste heat boilers for power generation or other industrial purposes. In this process, a large number of pipelines are needed to transport these high-temperature gases.

[0003] In the existing technology, some high-temperature gases contain a large amount of waste slag. Before being transported to the waste slag treatment agency, they are transported for a long time. The coke ash will adhere to the pipeline wall and gradually accumulate and harden to form slag scale. Especially for pipelines transported from top to bottom, slag scale is more likely to accumulate at the bends that are impacted, which not only affects the subsequent gas transmission, but also makes the pipeline unusable.

[0009] In the above technical solution, further, a C-shaped plate is inserted and slidably connected inside the No. 1 dust accumulation plate, two dust baffles are fixedly connected to the outer wall of the C-shaped plate, and the dust baffles are inserted and slidably connected inside the No. 1 dust accumulation plate, an adapter block is fixedly connected to the bottom of the C-shaped plate, and the adapter block is adapted to the movable rod, two guide rods are fixedly connected to the top of the inner side surface of the C-shaped plate, and the guide rods correspond to the positions of the sockets, and a reset spring is provided on the outer sleeve of the guide rods.

[0011] In the above technical solution, further, the outer wall of the second dust accumulation plate is fixedly connected with evenly distributed dust blocking blocks.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting up a pressure reducing pipeline and constructing another channel, when the gas being transmitted passes through the pressure reducing pipeline, the pressure at the turning part is naturally reduced, so that the impact degree of the turning part is reduced, and the adhesion of coke ash is naturally reduced, thus extending the service life of the turning part;

[0014] The No. 1 ash accumulation plate is an elastic structure. The angle of the No. 1 ash accumulation plate can be freely adjusted inside the connection box through the setting of the rotating shaft. The No. 1 ash accumulation plate is adjusted to be inclined toward the inside of the turning part, which naturally forms a part of the obstruction, so that the transmission channel of the turning part becomes narrow, and correspondingly more gas is transmitted to the inside of the lower pipeline through the pressure reducing pipeline. When the gas passes through, it first impacts the plate surface of the No. 1 ash accumulation plate, so that part of the gas enters the inside of the No. 1 ash accumulation plate and fills the inside of the connection box, and then is discharged from the lower rotating gap of the No. 1 ash accumulation plate to the inside of the turning part, and continues to enter the inside of the lower pipeline. In the long run, the surface of the No. 1 ash accumulation plate and the No. 2 ash accumulation plate will be adhered with coke ash, thereby reducing the adhesion of coke ash on the outer wall of the turning part. Through this design, the accumulation of coke ash inside the turning part is reduced;

[0015] By setting the second elastic member and the first elastic member, the second dust accumulation plate itself can vibrate. After being used for a certain period of time, the user opens the cover and uses a hook or other tool to hook the movable rod downward to drive the first dust accumulation plate to rotate as a whole to a state of tilting toward the inside of the connection box. At this time, the movable rod continues to be pulled down so that the movable rod continues to rotate around the rotation axis, one end of which contacts the adapter block and continuously pushes the C-shaped plate upward inside the first dust accumulation plate. At the same time, the guide rod is inserted into the inside of the socket to compress the reset spring. When the guide rod After contacting the No. 2 ash accumulation plate, a force will be applied to the No. 2 ash accumulation plate, causing the No. 2 ash accumulation plate to vibrate. Due to the connection of the connecting column, the top surface of the No. 1 ash accumulation plate will also vibrate synchronously. Through this design, the movable rod can be continuously pulled to continuously vibrate the No. 2 ash accumulation plate and the No. 1 ash accumulation plate synchronously, artificially causing the coke ash attached to the No. 2 ash accumulation plate and the No. 1 ash accumulation plate to fall off and fall out of the connecting box through the closed mouth, thereby keeping the top surfaces of the No. 1 ash accumulation plate and the No. 2 ash accumulation plate clean and continuously and efficiently adsorbing the coke ash.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 6 A connecting pipeline for dry quenching waste heat power generation is shown, comprising an upper pipeline 1 and a lower pipeline 2, a turning portion 3 is fixedly connected between the upper pipeline 1 and the lower pipeline 2, a pressure reducing pipeline 4 is fixedly connected between the upper pipeline 1 and the lower pipeline 2, a connecting box 5 is fixedly connected to one side of the turning portion 3, a closing port 6 is provided at the bottom of the connecting box 5, and a sealing cover is screwed to the outer wall of the closing port 6.

[0025] In the above arrangement, by setting up a pressure reducing pipe 4, another channel is constructed. When the gas being transmitted passes through the pressure reducing pipe 4, the pressure at the turning part 3 is naturally reduced, so that the impact degree of the turning part 3 is reduced, which naturally reduces the adhesion of coke ash and extends the service life of the turning part 3.

[0026] An ash accumulation component is provided inside the connection box 5, and the ash accumulation component is used to collect coke ash. The ash accumulation component includes a No. 1 ash accumulation plate 7 arranged inside the connection box 5. The outer wall of the No. 1 ash accumulation plate 7 is provided with two movable holes 9. The outer wall of the No. 1 ash accumulation plate 7 is fixedly connected with a rotating shaft 10 on both sides, and the rotating shaft 10 is inserted and rotatably connected to the inner wall of the connection box 5. The outer wall of the No. 1 ash accumulation plate 7 is provided with an inner cavity 11. The outer wall of the No. 1 ash accumulation plate 7 is provided with evenly distributed ash holes 8, and the ash holes 8 are connected to the inner cavity 11. A No. 2 ash accumulation plate 15 is provided inside the inner cavity 11. Evenly distributed connecting columns 19 are fixedly connected between the No. 2 ash accumulation plate 15 and the No. 1 ash accumulation plate 7. Two sockets 23 are fixedly connected to the bottom of one side of the No. 1 ash accumulation plate 7.

[0027] In the above arrangement, the No. 1 ash accumulation plate 7 is an elastic structure, and the angle of the No. 1 ash accumulation plate 7 can be freely adjusted inside the connecting box 5 through the arranged rotating shaft 10. The No. 1 ash accumulation plate 7 is adjusted to be inclined toward the inside of the turning part 3, and a part of the obstruction is naturally formed, so that the transmission channel of the turning part 3 becomes narrow, and accordingly more gas is transmitted to the inside of the lower pipe 2 through the pressure reducing pipe 4. When the gas passes through, it preferentially impacts the plate surface of the No. 1 ash accumulation plate 7, so that a part of the gas enters the inside of the No. 1 ash accumulation plate 7 and fills the inside of the connecting box 5, and is discharged from the lower rotating gap of the No. 1 ash accumulation plate 7 to the inside of the turning part 3, and continues to enter the inside of the lower pipe 2. In the long run, the surfaces of the No. 1 ash accumulation plate 7 and the No. 2 ash accumulation plate 15 will be adhered with coke ash, thereby reducing the adhesion of coke ash on the outer wall of the turning part 3. Through this design, the accumulation of coke ash inside the turning part 3 is reduced.

[0028] A uniformly distributed No. 1 elastic member 16 is fixedly connected between the No. 2 dust accumulation plate 15 and the inner wall of the inner cavity 11, and the shape of the No. 1 elastic member 16 is arc-shaped. Two fixed plates 14 are fixedly connected to the interior of the inner cavity 11. A movable rod 12 is connected between the two fixed plates 14 through a rotating shaft, and the movable rod 12 is inserted and slidably connected to the outer side of the No. 1 dust accumulation plate 7. A C-shaped plate 13 is inserted and slidably connected to the interior of the No. 1 dust accumulation plate 7. The outer wall of the C-shaped plate 13 is fixedly connected to two dust baffles. 24, and the dust baffle 24 is inserted and slidably connected to the inside of the No. 1 dust accumulation plate 7, the bottom of the C-shaped plate 13 is fixedly connected with an adapter block 20, and the adapter block 20 is adapted to the movable rod 12, and the top of the inner side of the C-shaped plate 13 is fixedly connected with two guide rods 21, and the positions of the guide rods 21 and the sockets 23 correspond, and the outer sleeve of the guide rods 21 is provided with a reset spring 22, and a uniformly distributed No. 2 elastic member 17 is fixedly connected between one side of the No. 2 dust accumulation plate 15 and the fixed plate 14.

[0029] In the above arrangement, by arranging the second elastic member 17 and the first elastic member 16, the second dust accumulation plate 15 itself can vibrate. After being used for a certain period of time, the user opens the cover and uses a hook or other tool to hook the movable rod 12 and press down to drive the first dust accumulation plate 7 to rotate as a whole to a state tilted toward the inside of the connection box 5. At this time, the movable rod 12 continues to rotate around the rotating shaft 10, one end of which contacts the adapter block 20 and continuously pushes the C-shaped plate 13 upward inside the first dust accumulation plate 7. At the same time, the guide rod 21 is inserted into the inside of the socket 23, causing the reset spring 22 to compress. When the guide rod 21 contacts the second ash accumulation plate 15, a force will be applied to the second ash accumulation plate 15, causing the second ash accumulation plate 15 to vibrate. Due to the connection of the connecting column 19, the top surface of the first ash accumulation plate 7 will also vibrate synchronously. Through this design, the movable rod 12 can be continuously pulled to continuously vibrate the second ash accumulation plate 15 and the first ash accumulation plate 7 synchronously, artificially causing the coke ash attached to the second ash accumulation plate 15 and the first ash accumulation plate 7 to fall off and fall out of the connecting box 5 through the closed port 6, thereby keeping the top surfaces of the first ash accumulation plate 7 and the second ash accumulation plate 15 clean and continuously and efficiently adsorbing the coke ash.

[0030] The outer wall of the second dust accumulation plate 15 is fixedly connected with evenly distributed dust blocking blocks 18 .

[0031] This design can effectively prevent the coke ash from being blown.

[0032] Working principle:

[0033] By setting up the pressure reducing pipeline 4 and constructing another channel, when the gas being transmitted passes through the pressure reducing pipeline 4, the pressure at the turning part 3 is naturally reduced, so that the impact degree of the turning part 3 is reduced, and the adhesion of the coke ash is naturally reduced, and the service life of the turning part 3 is extended;

[0034] The first dust accumulation plate 7 is an elastic structure. The angle of the first dust accumulation plate 7 can be freely adjusted inside the connection box 5 by means of the rotating shaft 10. The first dust accumulation plate 7 is adjusted to be inclined toward the inside of the turning part 3, and a part of the obstruction is naturally formed, so that the transmission channel of the turning part 3 becomes narrow, and correspondingly more gas is transmitted to the inside of the lower pipe 2 through the pressure reducing pipe 4. When the gas passes through, it first impacts the plate surface of the first dust accumulation plate 7, so that a part of the gas enters the inside of the first dust accumulation plate 7 and fills the inside of the connection box 5, and then is discharged from the lower rotating gap of the first dust accumulation plate 7 to the inside of the turning part 3, and continues to enter the inside of the lower pipe 2. In the long run, the outer surfaces of the first dust accumulation plate 7 and the second dust accumulation plate 15 will be adhered with coke, thereby reducing the adhesion of coke to the outer wall of the turning part 3. Through this design, the accumulation of coke inside the turning part 3 is reduced.

[0035] By setting the second elastic member 17 and the first elastic member 16, the second dust accumulation plate 15 itself can vibrate. After being used for a certain period of time, the user opens the cover and uses a hook or other tool to hook the movable rod 12 to press down and drive the first dust accumulation plate 7 to rotate as a whole to a state tilted toward the inside of the connection box 5. At this time, the movable rod 12 continues to rotate around the rotating shaft 10, one end of which abuts against the adapter block 20 and continuously pushes the C-shaped plate 13 to move upward inside the first dust accumulation plate 7. At the same time, the guide rod 21 is inserted into the inside of the socket 23, so that the reset spring 22 is compressed. When the guide rod 21 is inserted into the inside of the socket 23, the reset spring 22 is compressed. After contacting the second ash accumulation plate 15, 21 will give a force to the second ash accumulation plate 15, causing the second ash accumulation plate 15 to vibrate. Due to the connection of the connecting column 19, the top surface of the first ash accumulation plate 7 is also vibrated synchronously. Through this design, the second ash accumulation plate 15 and the first ash accumulation plate 7 can be continuously vibrated synchronously by continuously pulling the movable rod 12, artificially causing the coke ash attached to the second ash accumulation plate 15 and the first ash accumulation plate 7 to fall off and fall out of the interior of the connecting box 5 through the closed port 6, thereby keeping the top surfaces of the first ash accumulation plate 7 and the second ash accumulation plate 15 clean and continuously and efficiently adsorbing the coke ash.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
