Description

Technical Field

[0001] The invention discloses a stable coke quenching station, and relates to the technical field of coke quenching equipment, in particular to a coke quenching station with stable wet coke quenching. Background Art

[0002] There are two main types of coke quenching methods in the coking industry: dry quenching and wet quenching. Among them, wet quenching usually adopts the top high-pressure water quenching process, and the ordinary quenching car equipped is a special quenching vehicle that uses normal temperature water for quenching. It runs on the quenching car track on the coke side of the coke oven, towed and operated by an electric locomotive, and is used to transport the red coke pushed out of the carbonization chamber, transport it to the quenching tower for wet quenching, and unload the quenched coke onto the coke drying platform. Usually in one working cycle, the quenching car has to withstand high-temperature baking and rapid water cooling, and work three shifts a day without stopping, which is a heavy task. Among coke oven equipment, the wet quenching car has the shortest service life, especially some coking plants use phenol-containing wastewater to quench coke, which corrodes the wet quenching car more seriously. The quenching car is corroded after about a year of use. In addition, this quenching process has many disadvantages, such as the quenching time is too long, the moisture content of the finished coke is too high, the red coke in the thick coke pile cannot be quenched completely, the residual red coke damages the coke drying platform and coke conveyor belt, and wastes water resources. In addition, the most commonly used dry quenching also has the disadvantages of large investment, long construction period, huge energy consumption of elevators during operation, high nitrogen production cost, and dust is difficult to collect when red coke is loaded.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of stable coke quenching station to overcome the problems existing in the prior art. Summary of the invention

[0004] According to the above-mentioned prior art, the wet coke quenching has long quenching time, high water content of finished products, and the coke is not thoroughly quenched, which causes damage to the coke drying platform and conveyor belt, wastes water, and the service life of the coke quenching vehicle; the dry coke quenching has large investment, long construction period, high energy consumption, and dust is not easy to collect. A stable coke quenching station is provided. The present invention mainly uses a dust collecting hood and a splash-proof coke plug plate to create a fully enclosed coke quenching environment, providing the necessary conditions for dust removal and whitening, and exhaust gas emission that meets the standards, thereby improving the service life of the coke quenching equipment, shortening the coke quenching time, ensuring that the hot coke is quenched once, reducing the water content of the finished coke, and making the coke particles uniform in size.

[0005] The technical means adopted by the present invention are as follows:

[0006] A stable coke quenching station comprises: a coke quenching station body, a trough lifting mechanism, a dust removal system, a coke splash-proof plug plate, a dust collecting hood, a coke quenching trough, a coke quenching pool, a secondary coke pushing machine and a tertiary coke moving machine;

[0007] Furthermore, a coke quenching tank is provided below the coke quenching station body;

[0008] Furthermore, a quenching pool is provided at the lower part of the quenching tank;

[0009] Further, the front side of the coke quenching tank is hinged to the foundation;

[0010] Furthermore, a trough lifting mechanism is installed on the top of the quenching station body, and its chain is hinged to the rear side of the quenching trough;

[0011] Furthermore, a water system is provided on the top of the dust collecting hood and in the quenching tank, for quenching the coke quenching tank by combining top spraying and bottom water gushing;

[0012] Furthermore, a dust collecting hood is arranged inside the coke quenching station body at the upper part of the coke quenching tank, and is connected to the dust removal system outside the coke quenching station body through a flue gas duct;

[0013] Furthermore, the coke pushing driving mechanism of the secondary coke pushing machine is arranged on the foundation outside one end of the coke quenching tank, and the coke pushing rod thereof can be horizontally extended and retracted, penetrates the coke quenching tower, enters and exits the coke quenching station from one end, and reaches the upper part of the coke quenching tank;

[0014] Furthermore, the three-time coke moving machine is arranged on the foundation outside the rear side of the coke quenching tank, and its coke supporting plate can be horizontally extended and retracted, enter and exit the coke quenching station body, and reach the upper part of the coke quenching tank;

[0015] Furthermore, anti-coke splash plates are arranged above both ends of the quenching groove, the fixed parts of which are fixed to the two ends of the quenching station body, and the movable parts can be raised and lowered in an inclined state to reach above both ends of the quenching groove, so as to close the secondary coke pushing gap of the dust collecting hood, provide conditions for collecting dust and smoke, and prevent red coke from splashing during the quenching process.

[0016] Furthermore, the trough lifting mechanism includes: two drive shafts, a trough lifting motor, a double-output shaft reducer, two anchor chain wheels, two anchor chains, a pull plate and a counterweight;

[0017] Furthermore, the slot lifting motor is fixedly installed on the upper part of the quenching station body as a power source, and is connected to the two drive shafts through a double-output shaft reducer, and the axis lines of the two drive shafts coincide;

[0018] Furthermore, a chain wheel is fixed to each end of the two drive shafts;

[0019] Furthermore, two anchor chain wheels are installed at both ends of the upper part of the quenching station body through sprocket seats; the chain petals of the two anchor chain wheels are installed at exactly the same angle and keep rotating synchronously;

[0020] Furthermore, two anchor chains are respectively mounted on two anchor chain wheels, one end of which is equipped with a counterweight and the other end is hinged to the coke quenching tank through a pull plate;

[0021] Furthermore, the two anchor chains are synchronously retracted and released, forcing the rear ends of the coke quenching tank to rise and fall synchronously. Under the gravity of the counterweight, the anchor chains are always kept taut, and the tension generated by the counterweight can reduce the output torque and power of the power source to a certain extent, thereby achieving the purpose of energy saving.

[0022] Furthermore, the anti-splashing plug plate comprises: two sets of annular plug plate chains, a movable plug plate, a plug plate driving mechanism and a plug plate fixing bracket;

[0023] Furthermore, the plug plate fixing bracket is fixed at both ends of the quenching station body;

[0024] Further, the plugboard driving mechanism is mounted on the movable plugboard and mounted on the plugboard fixing bracket;

[0025] Furthermore, a certain point on the ring of the two sets of ring-shaped plate chains is bolted to the movable plate;

[0026] Furthermore, the plugboard driving mechanism drives the two sets of plugboard chains to perform synchronous cyclic motion, forcing the lower edge of the movable plugboard in an inclined state to maintain a horizontal state and rise and fall.

[0027] Furthermore, when it is necessary to connect coke, the movable plug plate is in a retracted state, and the gap formed on its lower edge can allow the coke pushing rod head of the secondary coke pushing machine to pass through. When it is necessary to quench coke, the lower edge of the movable plug plate contacts the coke quenching groove, thereby achieving the purpose of sealing the dust collecting hood, facilitating the collection of smoke generated during coke quenching, and preventing coke from splashing out of the coke quenching groove.

[0028] Further, the quenching pool includes: an inner pool and an outer pool;

[0029] Furthermore, the inner pool is located at the bottom of the coke quenching tank; it needs to be in contact with and sealed at the bottom of the coke quenching tank, and is used for water injection at the bottom of the coke pile. Since the volume of the inner pool is small, it is easy to achieve the effect of a large amount of water quickly pouring into the red coke;

[0030] Furthermore, the outer tank is arranged outside the inner tank, and is used to collect the quenching water leaked and gathered from the quenching tank and the dust collecting hood.

[0031] Further, the secondary coke pushing machine comprises: a coke pushing driving mechanism and a coke pushing rod;

[0032] Furthermore, the coke pushing driving mechanism is fixed on the foundation outside one end of the coke quenching station body, driving the coke pushing rod to extend and retract horizontally, penetrate the coke quenching tower, enter and exit the coke quenching station body, and reach above the coke quenching tank;

[0033] Furthermore, when quenching or lifting the coke trough is required, the coke supporting plate (8-2) and the thrust plate (8-1) are in a retracted state to avoid interference with the coke splash-proof inserting plate (4) or the coke quenching trough (6) in motion.

[0034] Furthermore, the three-time focus shifting machine comprises: two sets of thrust plates, a focus supporting plate, two sets of annular focus shifting chains, and a focus shifting driving mechanism;

[0035] Furthermore, the focus shifting driving mechanism is fixedly mounted on the foundation outside the rear side of the quenching station body, and synchronously drives the two sets of focus shifting chains;

[0036] Furthermore, a certain point on the ring of the two sets of annular focus shifting chains is bolted to the focus supporting plate. When the two sets of focus shifting chains move synchronously, the surface of the focus supporting plate is forced to remain horizontal and extend and retract, enter and exit the coke quenching station, and reach the upper part of the coke quenching tank.

[0037] Furthermore, two sets of thrust plates are located above the coke supporting plate, perpendicular to the secondary coke pushing direction and the tertiary coke moving direction respectively, and the extension and folding actions are realized through the respective thrust plate folding mechanisms. The thrust plates need to be extended in the coke receiving condition to limit the position where the cake-shaped coke stops on the coke supporting plate, so as to ensure that the coke falls to a reasonable position in the coke quenching tank; the thrust plates need to be folded back in the coke quenching condition, the tank lifting condition and the coke unloading condition to avoid the interference between the thrust plates and the coke splashing plug plate when the coke splashing plug plate is lowered, and the interference between the thrust plates and the coke quenching tank when the coke quenching tank is lifted.

[0038] Furthermore, the thrust plate folding mechanism comprises a folding oil cylinder and a folding rod. One end of the folding rod is hinged on the foundation, and the other end is hinged to the thrust plate; one end of the folding oil cylinder is hinged on the foundation, and the other end is hinged to the folding rod.

[0039] Furthermore, when a secondary coke pushing operation is required, the coke supporting plate and the thrust plate are in an extended state to ensure that the coke is pushed to the top of the center of the coke quenching tank;

[0040] Furthermore, when three focus shifting operations are required, the focus supporting plate is gradually pulled back from the fully extended state, and the coke is blocked by the thrust plate in the extended state, and slides out of the focus supporting plate and falls into the coke quenching groove.

[0041] Furthermore, a large number of small holes for water injection are provided at the bottom of the quenching tank and the corresponding area of ​​the inner pool to ensure that the water injection flow rate can be met when quenching is required, while ensuring that the coke will not pass through the water injection holes into the quenching pool.

[0042] Furthermore, the bottom of the coke quenching trough can be lower than the coke quenching track on which the coke quenching car travels. By adopting a trough lifting mechanism to drive the coke quenching trough to produce a flipping and coke unloading method with a larger stroke, while ensuring that the falling height during three coke shifts is sufficient to break the coke cake, the slopes of the coke drying platforms corresponding to the coke quenching trough and the coke quenching car can be made coplanar, thereby allowing them to share the same set of coke conveyor belts.

[0043] The working process of the stable quenching station of the present invention is as follows:

[0044] The hot coke cake pushed out from the coke oven is transported to the coke quenching tower by the coke quenching car, and then pushed to the coke support plate of the tertiary coke moving machine located above the coke quenching tank by the secondary coke pusher. The coke support plate is pulled outward, and the coke cake is blocked by the thrust plate and falls into the coke quenching tank. After the gap is sealed with the splash-proof coke plug plate, water is poured into the coke quenching pool, and the bottom of the coke pile is quickly submerged to a certain thickness, and the top water system sprays water at the same time. The hot coke meets water all around to form steam, which is quickly extinguished in the sealed coke quenching tank. The generated flue gas is collected by the dust hood and discharged into the atmosphere after being purified by the dust removal system.

[0045] Coke quenching process: push coke once → transfer to the quenching station → dust removal system runs at high speed → push coke twice → move coke three times and drop it into the quenching tank → anti-splashing plug plate descends → dust removal system runs at high speed → water gushes from the bottom and water sprays from the top to quench coke → after quenching, dust removal system runs at high speed → anti-splashing plug plate rises → lift tank to unload coke → dust removal system runs at low speed → empty tank resets.

[0046] Compared with the prior art, the present invention has the following advantages:

[0047] 1. The stable coke quenching station provided by the present invention mainly uses water gushing from the bottom and water spraying from the top as a supplement. By flushing the bottom and top of the hot coke pile in all directions, the coke is split in the sealed cavity and then rolled around by water and steam, which can effectively shorten the quenching time, improve the one-time quenching success rate of the whole coke tank, eliminate red coke residue, and improve the quality of finished coke.

[0048] 2. The stable coke quenching station provided by the present invention has a process of falling and breaking during the transportation of coke cakes, so the finished coke particles are uniform in size;

[0049] 3. The stable coke quenching station provided by the present invention has good water sealing effect of the coke quenching tank, small demand for quenching water, and the coke quenching pool is divided into an inner pool and an outer pool. The inner pool needs to be sealed and is used for bottom water injection. Its volume is small, saving water resources;

[0050] 4. The stable coke quenching station provided by the present invention has a coke splash-proof plug plate that closes each gap of the dust collecting cover to form a fully enclosed space, providing conditions for collecting dust and smoke generated by coke quenching. It can also avoid the phenomenon of coke splashing and waste and damage to the main load-bearing parts;

[0051] 5. In the stable coke quenching station provided by the present invention, only the pull plate and the anchor chain in the trough lifting mechanism are exposed to the coke quenching operation area, and the station has strong corrosion resistance and high temperature resistance. This method effectively avoids the damage of the common wet coke quenching vehicles, the red coke and the quenching water to the traveling mechanism, the door opening mechanism and other relatively precise components, and adopts the method of implementing the red coke transfer and the coke quenching operation step by step, thereby improving the service life of the wet coke quenching equipment;

[0052] 6. The stable coke quenching station provided by the present invention does not use a stainless steel coke bucket structure, nor does it use a complex water system of a stable coke quenching vehicle, which reduces equipment failure points and greatly saves the owner's equipment cost and operating cost;

[0053] 7. The stable coke quenching station provided by the present invention can be used as a backup for the conventional coke quenching tower and the coke quenching station, thereby improving production efficiency and reducing the risk of shutdown due to equipment failure;

[0054] 8. The stable coke quenching station provided by the present invention has a coke quenching vehicle that can quench coke independently or cooperate with the coke quenching station to serve as a red coke transport vehicle. Its coke box can move horizontally along the secondary coke pushing direction and can be tilted as a whole toward the coke drying platform corresponding to the coke quenching tower to unload coke;

[0055] 9. The stable coke quenching station provided by the present invention has a simple structure, a low failure rate and is durable.

[0056] In summary, the technical solution of the present invention solves the problems in the prior art such as long quenching time of wet coke quenching, high moisture content of finished products, damage to the drying platform and conveyor belt caused by poor quenching, waste of water, and short service life of the quenching vehicle; and large investment, long construction period, high energy consumption, and difficulty in collecting dust in dry coke quenching.

[0072] When the coke quenching station is used for quenching, the conventional wet quenching car 12 acts as a red coke transfer car, which is used to receive the hot coke 9 pushed out from the coke oven and transferred to the coke quenching tower 13. The coke 9 is transported by the secondary coke pusher 11 and the tertiary coke transfer machine 8. The coke 9 falls and breaks into pieces and enters the coke quenching tank 6 located below the coke quenching station body 1. The gaps of the dust collecting cover 5 are closed by the anti-splash coke plug plate 4, and the dust removal system 3 runs at high speed. The water system 10 is started, and the quenching water quickly enters the quenching tank filled with hot coke 9 from the bottom. The coke trough 6 contacts and submerges the red-hot coke 9 at a certain depth, and water is sprayed on the top at the same time. The red-hot coke is rapidly vaporized in contact with water all around, generating a large amount of water vapor.

When it is necessary to connect coke, the movable plug board 4-2 is in a retracted state, and the gap formed on its lower edge can be used for the coke pushing rod head of the secondary coke pushing machine 11 to pass through. When it is necessary to quench coke, the lower edge of the movable plug board 4-2 contacts the coke quenching groove 6, so as to achieve the purpose of sealing the dust collecting cover 5, facilitate the collection of smoke generated during coke quenching, and prevent coke from splashing out of the coke quenching groove.

[0075] The quenching pool 7 includes: an inner pool 7-1 and an outer pool 7-2; the inner pool 7-1 is located at the bottom of the quenching tank 6; it needs to be in contact with and sealed with the bottom of the quenching tank 6, and is used for injecting water into the bottom of the coke pile. Since the volume of the inner pool is small, it is easy to achieve the effect of a large amount of water quickly pouring into the red coke; the outer pool 7-2 is arranged outside the inner pool 7-1; it is used to collect quenching water leaked and gathered from the quenching tank 6 and the dust collecting hood 5.

[0078] When three focus shifting operations are required, the focus supporting plate 8-2 is gradually pulled back from the fully extended state, and the coke 9 is blocked by the thrust plate 8-1 in the extended state, and slides out of the focus supporting plate 8-2 and falls into the coke quenching groove 6;

[0079] When it is necessary to quench the coke or lift the coke quenching groove, the coke supporting plate 8-2 and the thrust plate 8-1 are in a retracted state to avoid interference with the coke splash-proof inserting plate 4 or the coke quenching groove 6 in motion.

[0080] A large number of small holes for water injection are arranged at the bottom of the quenching tank 6 and the corresponding area of ​​the inner pool 7-1 to ensure that the water injection flow rate can be met when quenching is required, and at the same time ensure that coke will not pass through the water injection holes into the quenching pool.

[0081] The bottom of the quenching trough 6 can be lower than the quenching track on which the quenching car 12 travels. By adopting the trough lifting mechanism 2 to drive the quenching trough 6 to produce a flipping and unloading method with a larger stroke, on the premise of ensuring that the falling height during three coke shifts is sufficient to break the cake-shaped coke 9, the slopes of the coke drying platforms 14 corresponding to the quenching trough 6 and the quenching car 12 can be made coplanar, thereby allowing them to share the same set of coke conveyor belts.
