Description

Technical Field

[0001] This invention relates to the field of coke preparation technology, specifically to a water-saving and emission-reducing coke quenching process and method using spray water replenishment. Background Technology

[0002] In the coke production industry, coke is produced by heating and dry distilling it in an industrial furnace. After being discharged from the coke furnace, the coke remains at a high temperature and continues to react with air, maintaining its combustion and red-hot state. This not only complicates subsequent system processing but also increases the combustion loss of the coke. Traditional processes involve soaking the red-hot coke discharged from the coke furnace in water or spraying it with a large amount of quenching water to quickly extinguish the coke.

[0003] Red-hot coke has a temperature of approximately 600–1200℃ and contains a large amount of sensible heat. When quenching water comes into direct contact with the coke, it produces a violent vaporization phenomenon, carrying away the heat from the coke. The quenching steam and the water isolate the coke from the air, blocking the exothermic combustion reaction and achieving the purpose of rapidly quenching the coke.

[0004] Traditional wet quenching processes have several problems. Red-hot coke contains a large amount of sensible heat, requiring half the mass of quenching water to be converted into quenching steam for rapid coke quenching. After conversion, the quenching water expands more than 1000 times in volume, and contains coke particles and dust blown up during the vaporization of the quenching water. Currently, there is no economical, efficient, and simple device to handle or reuse this intermittent, short-term, large-scale release of quenching steam mixed with a large amount of dust. Conventional devices typically use simple methods to reduce dust in the flue gas before venting it.

[0005] With increasing environmental awareness and industry requirements, reducing the consumption of water resources in traditional wet quenching processes and reducing the emissions of flue gas and dust from traditional wet quenching systems have become critical technological shortcomings that need to be addressed in the wet quenching process of the coke preparation industry. Although dry quenching processes and equipment can greatly improve the recovery and utilization of sensible heat from coke and reduce environmental emission pressure, their high construction and operating costs, minimum scale requirements, and strict and complex operation cannot meet the needs of enterprises at all levels in the industry. Summary of the Invention

[0006] The purpose of this invention is to provide a water-saving and emission-reducing coke quenching process and method that uses spray water replenishment. Compared with the traditional wet coke quenching process, this new coke quenching process and method recovers some of the water vapor and dust in the coke quenching operation by spraying coke quenching steam with coke quenching replenishment water, thereby achieving water-saving and emission-reducing effects.

A sleeve extends through the housing and the high-lift quenching tower. The horizontal tube and the inner wall of the sleeve are fixed to each other by a sealed bearing, providing conditions for the rotation of the horizontal tube. The horizontal tubes are connected by a transmission mechanism. A forward and reverse drive mechanism is used to provide rotational power to the horizontal tube.

[0009] Preferably, the forward and reverse drive mechanism includes a power unit, a first transmission rod, a second transmission rod, and a third transmission rod. The first, second, and third transmission rods are all rotatably connected to the inner wall of the housing.

A second gear and a second half gear are respectively bolted to the surface of the second transmission rod. A third gear and a fourth gear are bolted to the surface of the third transmission rod. A fourth gear that meshes with the third gear is bolted to the surface of the horizontal tube. The first gear meshes with the second gear, and the first half gear and the second half gear alternately mesh with the fourth gear. The power unit is used to drive the first transmission rod to rotate.

[0010] Preferably, the first gear has the same size as the second gear, and the radius of the third gear is smaller than that of the fifth gear.

[0011] Preferably, both the first and second half gears are designed as half-circles, and the tooth distribution is symmetrical.

[0012] Preferably, the high-lift quenching tower is further provided with a support frame inside, and the other end of the horizontal tube is rotatably connected to the support frame.

[0013] Preferably, the quenching system further includes: The flue gas outlet pipe is connected to the interior of the high-lift quenching tower. A flue gas treatment device, which is connected to the flue gas outlet pipe; The coke quenching water supply pipe extends into the interior of the coke quenching water supply pipe; The condensate return pipe is connected to the bottom of the coke quenching water supply pipe, and the other end is connected to the circulating water pool. An exhaust fan, the inlet of which is connected to the top of the flue gas treatment device; The flue gas return pipeline is connected to the outlet end of the induced draft fan, and the other end is connected to the high-lift quenching tower.

[0014] Preferably, the power unit is an electric motor or a hydrodynamic component.

[0015] Preferably, the hydrodynamic element consists of a housing, an impeller, a long rod, and a connecting pipe. There are two sets of connecting pipes, which are respectively connected to both sides of the housing to connect the housing to the connecting pipeline. The impeller is rotatably connected to the inside of the housing and fixed to the long rod. The other end of the long rod is fixed to the first transmission rod.

[0016] A water-saving and emission-reducing coke quenching method using spray water replenishment includes the following steps: Step S1: The circulating water pump pumps the water in the circulating water tank to the buffer water tank, which is at a high position, and the container carrying the red coke enters the high-lift coke quenching tower. Step S2: The quenching water is sent to the high-lift quenching tower through the connecting pipe, where it comes into contact with the coke to exchange heat and form quenching steam, which quenches the coke. Step S3: The water replenishment mechanism inside the quenching tower is sprayed into the quenching tower through the nozzles.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

The water is added to the coke quenching system in the form of atomized spray to spray and reduce dust, cool and condense the coke quenching flue gas. The dust particles and condensate in the flue gas are carried back to the sedimentation system together. This can significantly reduce water consumption due to water vapor emission and significantly reduce dust in the emitted flue gas. It is also applicable to the process of cooling industrial materials by directly contacting water for heat exchange and using the principle of water evaporation heat absorption. It has the effect of recovering evaporated water vapor and reducing the dust content in the steam.

[0018] 2. The present invention, through the setting of the spraying mechanism inside the quenching tower, uses the power unit in the forward and reverse drive mechanism to drive the first transmission rod to rotate, and with the cooperation of the second transmission rod and the third transmission rod, etc., to drive the horizontal pipe to alternately rotate forward and reverse inside the quenching tower, so that the nozzle swings back and forth, expands the spraying range, and forms a more uniform water curtain.

[0019] 3. This invention uses a water-driven impeller and long rod to drive the first transmission rod to rotate by designing the power unit. No additional power is required. During the water delivery process, the nozzle can swing, which slightly reduces the energy consumption of the device. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9 As shown, a water-saving and emission-reducing coke quenching process using spray water replenishment employs the following coke quenching system as the equipment used in the process. The coke quenching system includes a carrying container 1, a high-lift coke quenching tower 2, a circulating water tank 3, a circulating water pump 4, a buffer water tank 5, and a spraying mechanism 7 inside the coke quenching tower. The carrying container 1 is used to hold coke. The high-lift coke quenching tower 2 is the core of the process. The circulating water tank 3 and the high-lift coke quenching tower 2 are interconnected by pipelines to recover water vapor and condense it into droplets. The circulating water pump 4 is used to transport water inside the circulating water tank 3. The buffer water tank 5 is interconnected with the circulating water pump 4 by pipelines. The buffer water tank 5 is also connected to a connecting pipe 6 that connects to the carrying container 1. The spraying mechanism 7 inside the coke quenching tower is used to replenish water to the carrying container 1.

[0024] Furthermore, the spraying mechanism 7 inside the quenching tower includes horizontal pipes 710, nozzles 720, a housing 740, connecting pipes 750, a sleeve 760, and a forward / reverse drive mechanism 770. Several horizontal pipes 710 are arranged above the supporting container 1. Several nozzles 720 are interconnected with the horizontal pipes 710 and are equidistantly arranged. The housing 740 is located outside the high-lift quenching tower 2. The connecting pipes 750 are composed of multiple pipe sections and are close to the horizontal pipes 710. The end connection is provided with a pipe rotation connector 780, which connects itself to the horizontal pipe 710 without obstructing the rotation of the horizontal pipe 710. The sleeve 760 penetrates the shell 740 and the high-lift quenching tower 2. The inner walls of the horizontal pipe 710 and the sleeve 760 are fixed to each other by a sealed bearing, providing conditions for the rotation of the horizontal pipe 710. The horizontal pipes 710 are connected by a transmission. The forward and reverse drive mechanism 770 is used to provide rotational power to the horizontal pipe 710. The connecting pipe 750 is connected to an external water supply device.

[0025] The forward and reverse drive mechanism 770 includes a power unit 771, a first transmission rod 772, a second transmission rod 773, and a third transmission rod 774. The first transmission rod 772, second transmission rod 773, and third transmission rod 774 are all rotatably connected to the inner wall of the housing 740. A first gear 775 and a first half gear 776 are respectively bolted to the surface of the first transmission rod 772. A second gear 777 and a second half gear 778 are respectively bolted to the surface of the second transmission rod 773. A third gear 779 and a fourth gear 7710 are bolted to the surface of the third transmission rod 774. A fourth gear 7710, meshing with the third gear 779, is bolted to the surface of the horizontal tube 710. The first gear 775 and the third half gear 776... Two gears 777 mesh with each other, and the first half gear 776 and the second half gear 778 alternately mesh with the fourth gear 7710. The power unit 771 is used to drive the first transmission rod 772 to rotate. The size of the first gear 775 is the same as that of the second gear 777. The radius of the third gear 779 is smaller than that of the fifth gear 7711. In fact, the rotational speed of the first transmission rod 772 is the same as that of the second transmission rod 773. The first half gear 776 and the second half gear 778 are both half-circle designs, and the tooth distribution is symmetrical. The high-lift quenching tower 2 is also equipped with a support 730, and the other end of the horizontal tube 710 is rotatably connected to the support 730 to increase the rotational stability of the horizontal tube 710.

[0026] The power unit 771 is an electric motor or a hydrodynamic component.

[0027] During water replenishment, water enters the horizontal pipe 710 through the connecting pipe 750 and the pipe rotating connector 780, and is sprayed onto the coke by the nozzle 720. The motor is turned on to drive the first transmission rod 772 to rotate, and through the first gear 775 and the second gear 777, it drives the second transmission rod 773 to rotate. The rotation speed is the same, but the rotation direction is opposite. The first half gear 776 and the second half gear 778 take turns meshing with the fourth gear 7710, which in turn drives the third long rod 771c to alternately rotate forward and reverse, thereby driving the horizontal pipe 710 to alternately rotate forward and reverse, causing the nozzle 720 to oscillate, and making the water replenishment more even.

[0028] When the power unit 771 is a hydrodynamic element, the hydrodynamic element consists of a housing 771a, an impeller 771b, a long rod 771c, and a connecting pipe 771d. There are two sets of connecting pipes 771d, which are respectively connected to both sides of the housing 771a, connecting the housing 771a to the connecting pipe 750. The impeller 771b is rotatably connected to the inside of the housing 771a and fixed to the long rod 771c. The other end of the long rod 771c is fixed to the first transmission rod 772. When water passes through the connecting pipe 750, some water enters the inside of the housing 771a through the connecting pipe 771d to drive the impeller 771b and the long rod 771c to rotate, thereby driving the first long rod 771c to rotate. The power is provided by water supply, eliminating the need for a power source.

[0029] Example 1: The coke quenching system employs a water-saving and emission-reducing quenching process using a high-lift quenching tower 2 for water replenishment. Multiple horizontal pipes 710 are arranged inside the quenching tower, and multiple nozzles 720 are installed. A circulating water pump 4 pumps water from the circulating water tank to a buffer water tank 5, which is positioned at a high level. A carrying container 1 carries red-hot coke into the high-lift quenching tower 2. Quenching water is delivered to the high-lift quenching tower 2 through a connecting pipe 6, where it contacts the coke for heat exchange, forming quenching steam that quenches the coke. A spraying mechanism 7 inside the quenching tower replenishes water by spraying it through nozzles 720. The nozzles 720 oscillate back and forth, spraying evenly to form an atomized water curtain, which directly contacts the quenching steam for heat exchange. The water vapor condenses into droplets, which, along with dust in the flue gas, settle to the bottom of the high-lift quenching tower 2 and flow with the quenching water and replenishing spray water to the circulating water tank 3.

[0030] Example 2: The quenching system also includes a flue gas outlet pipe 8, a flue gas treatment device 9, a quenching water supply pipe 10, a condensate return pipe 11, an induced draft fan 12, and a flue gas return pipe 13. The flue gas outlet pipe 8 is interconnected with the interior of the high-lift quenching tower 2. The flue gas treatment device 9 is interconnected with the flue gas outlet pipe 8. The quenching water supply pipe 10 extends into the interior of the quenching water supply pipe 10. The condensate return pipe 11 is interconnected with the bottom of the quenching water supply pipe 10, and its other end is interconnected with the circulating water pool 3. The inlet end of the induced draft fan 12 is connected to the top of the flue gas treatment device 9. The components are interconnected. The flue gas return pipe 13 is connected to the outlet end of the induced draft fan 12, and the other end is connected to the high-lift quenching tower 2. The external spray water replenishment and water-saving and emission-reducing wet quenching process of the quenching tower is suitable for the technical transformation and upgrading of the existing wet quenching system. According to the existing quenching system plan, the equipment and devices are reused to the greatest extent. The quenching tower is modified to add a flue gas outlet pipe 8 and set an induced draft fan 12 to draw the quenching flue gas to the flue gas treatment device 9. The replenishment water of the quenching system is supplied to the flue gas treatment device 9 to complete the replenishment of the water source consumed by the quenching system. The quenching water is collected at the bottom of the flue gas treatment system and sent to the quenching circulating water system through pipelines. When the quenching water is added to the flue gas treatment device 9, it is sprayed to create a water curtain or water mist environment in the pipeline and device of the flue gas treatment device 9, so that the quenching water and the quenching flue gas can come into full contact. After the quenching flue gas comes into contact with the sprayed water curtain or water mist, it exchanges heat and cools down. After condensation, it forms droplets, which are collected at the bottom of the flue gas treatment device 9 along with the sprayed water and enter the circulating water pool 3.

[0031] Dust particles in the quenching flue gas are adsorbed and adhered to by the water curtain formed by the spraying of quenching water, the spray or steam condensation to form water mist, and they are collected at the bottom of the flue gas system along with the sprayed water and enter the quenching water circulation system. When the quenching water is added to the flue gas treatment device 9, it will generate a part of the spraying suction force to assist the flue gas to run to the subsequent system. The flue gas treatment device 9 adopts a cyclone device with spraying function. Through spraying washing, condensation and sedimentation, it simultaneously completes the condensation of quenching steam and the collection of particulate dust. Then, by using gravity and the centrifugal effect of the cyclone device, the condensed water and dust are separated from the bottom of the device.

[0032] The flue gas treated by the flue gas treatment device 9 is drawn out from the top of the device by the induced draft fan 12, sent back to the upper part of the quenching tower through the flue gas return pipeline 13, and discharged from the original venting channel of the quenching tower.

[0033] After being treated by the quenching flue gas treatment system, both the total amount of flue gas and the dust concentration in the flue gas are significantly reduced, resulting in significant water conservation and emission reduction effects.

[0034] The quenching steam is drawn from the quenching tower, treated to save water and reduce emissions, and then sent back to the quenching tower for venting. Compared with the old scheme, the entire technical upgrade process does not add any new organized or unorganized emission points.

[0035] The technical upgrade project for the coke quenching system, which adopts a water-saving and emission-reducing coke quenching process using external full-spray water replenishment, requires the following modifications to the existing coke quenching system: 1. Add a partition device or partition structure inside the quenching tower cavity. When the partition device is open, the functional structure of the quenching tower remains unchanged; when the quenching partition device is closed, the quenching flue gas can be directly discharged. The quenching tower space is divided into two cavities, the lower part is the quenching space, and the upper part is connected to the top discharge port of the quenching tower.

[0036] 2. Flue gas return pipes 13 are installed before and after the quenching tower isolation equipment for the export of quenching flue gas and the return channel of treated flue gas.

[0037] 3. A wet cyclone condenser is installed outside the quenching tower as a flue gas treatment device 9; 4. A flue gas induced draft fan is installed after the flue gas treatment device 9 to provide power for the extraction of quenching flue gas and the emission of treated flue gas.

[0038] The circulating water pump 4 pumps the water in the circulating water tank 3 to the high-level buffer water tank 5. The carrying container 1 carries the red coke into the quenching tower. The quenching water is sent to the quenching tower through the quenching pipe, where it contacts the coke for heat exchange and quenches the coke. The quenching flue gas accumulates at the bottom of the quenching tower and is drawn out by the flue gas outlet pipe 8 and sent to the flue gas treatment device 9, which is the wet cyclone condenser. The quenching makeup water is sprayed in the flue gas outlet pipe 8 and the flue gas treatment device 9 to form an atomized water curtain, which directly contacts the quenching steam for heat exchange. The water vapor condenses into droplets, and the condensate droplets adhere to the coke powder. Under the action of the cyclone condenser, they settle down to the bottom of the quenching tower along with the sprayed water curtain and flow to the circulating water tank 3. The remaining flue gas after treatment is returned to the quenching tower by the exhaust fan 12 and sent to the top of the quenching tower, where it is released from the quenching tower outlet.
