Description

Technical Field

[0001] The present invention relates to the technical field of coking, and in particular to a method for discharging tail coke, and more specifically, a method for extinguishing and collecting tail coke of a top-charging coke oven. Background Art

[0002] When discharging coke from a top-charging coke oven (such as a commonly used 6m top-charging coke oven), equipment such as a coke guide car and a coke quenching trolley are required. For a long time, during production, the coke guide car uses a scraper conveyor mechanism to extinguish and convey the tail coke at the furnace head and tail (which can be simply referred to as tail coke). Since the tail coke at the furnace head and tail is in direct contact with the scraper conveyor mechanism, it is extremely easy to cause jamming of the conveying chain of the scraper conveyor, and frequently faults such as chain breakage occur. The frequent faults of the scraper conveyor force the coke guide car to stop running, and the cleaning work of the tail coke at the furnace head and tail cannot be carried out normally, resulting in long-term accumulation of red coke, and then making the on-vehicle equipment easily burned out, posing a risk to the normal coke discharging of the coke guide car. Therefore, how to avoid the abnormal progress of the cleaning work caused by the failure of the coke guide car is a problem that needs to be solved. Summary of the Invention

[0003] The embodiment of the present invention provides a method for extinguishing and collecting tail coke of a top-charging coke oven, so as to avoid the failure of the coke guide car caused by the direct contact between the scraper conveyor mechanism and the tail coke, thereby ensuring the normal progress of the cleaning work of the tail coke.

[0004] To achieve the above object, the embodiment of the present invention provides a method for extinguishing and collecting tail coke of a top-charging coke oven, including: moving the coke guide car to a predetermined position on the coke oven side, and moving the coke quenching trolley to a predetermined position on the coke oven side; when the tail coke is output from the coke oven, receiving the tail coke through an inclined tail coke chute arranged on the coke guide car, so that the tail coke falls into the top end of the tail coke chute; supplying water to the top end of the tail coke chute through a high-pressure water pump, so that the tail coke is cooled and extinguished, and the tail coke slides down to a coke-water separation hopper arranged on the coke quenching trolley under the action of hydraulic scouring; separating the tail coke from the water through the coke-water separation hopper.

[0005] Further, supplying water to the top end of the tail coke chute through a high-pressure water pump specifically includes: supplying water to the high-pressure water pump by using an upper water tank arranged on the coke guide car.

[0006] Further, the method for extinguishing and collecting tail coke of a top-charging coke oven further includes: transferring the separated water to a water collection tank arranged on the coke quenching trolley.

[0007] Further, the method for extinguishing and collecting tail coke of a top-charging coke oven further includes: purifying the water through the water collection tank to obtain purified water.

[0008] Furthermore, the method for quenching and collecting tail coke of a top-loaded coke oven also includes: connecting the fixed end of a return water hose to an upper water tank; when a return water operation is required, lowering the free end of the return water hose and connecting it to a return water pump provided on the quenching trolley, and then transporting purified water back to the upper water tank through the return water pump; when a return water operation is not required, disconnecting the free end of the return water hose from the return water pump, and lifting the free end of the return water hose to a level above the top of the quenching trolley.

[0009] Furthermore, the method for extinguishing and collecting tail coke of a top-loading coke oven also includes: lifting or lowering the free end of the return water hose by means of a hose lifting device on the coke intercepting vehicle.

[0010] Furthermore, the method for quenching and collecting tail coke of a top-loading coke oven also includes: achieving connection between the free end of the return water pipe and the return water pump by means of a snap-fit joint.

[0011] Furthermore, water is purified by a water collecting tank, specifically including: dividing the water collecting tank by vertically arranged partitions to form a front chamber for sedimentation and stillness, and a rear chamber for containing purified water; when the liquid level in the front chamber is higher than the top of the partition, the water above the top of the partition overflows to the rear chamber, thereby obtaining purified water in the rear chamber.

[0012] Furthermore, the method for quenching and collecting tail coke of a top-loading coke oven also includes: laying a chute cover on the tail coke chute.

[0013] Furthermore, the method for quenching and collecting tail coke of a top-loading coke oven also includes: connecting a plurality of water collecting tanks respectively arranged on a plurality of quenching trolleys in parallel through a parallel interface arranged on the water collecting tanks.

[0014] The above technical solution has the following beneficial effects:

[0015] In this technical solution, the scraper mechanism of the prior art is no longer used. Instead, after the tail coke is introduced into the tail coke chute, the tail coke in the tail coke chute is flushed with high-pressure water, so that the tail coke can be quickly extinguished and smoothly transported to the coke-water separation bucket provided on the quenching trolley, thereby avoiding the jamming and disconnection of the conveying chain caused by the direct contact between the scraper mechanism and the tail coke in the prior art, ensuring that the coke intercepting car can be used normally, thereby ensuring the normal operation of production and improving the tail coke processing capacity.

[0016] In addition, this technical solution also has the following characteristics:

[0017] 1) The chute cover conveying method can reduce the exposure of workers to the harsh environment of coking, reduce the contact time of workers with dust and smoke, and effectively improve the safety and occupational health of employees.

[0018] 2) By setting up the chute cover plate, the high-temperature water vapor generated inside the tail coke chute due to the cooling of the high-temperature red coke when it encounters water can be sealed inside the tail coke chute, thereby isolating the escape of water vapor and reducing the phenomenon of excessive water loss.

[0019] 3) The furnace head tail coke collected by the coke-water separation hopper can be intermittently transferred to the coke cooling platform, avoiding the environmental protection problems caused by the easy smoking during the process of putting wet coke into the coke pot with red coke in the prior art.

[0020] 4) In the prior art, it is necessary to frequently clean the tail coke belt and replace the belt, etc., which greatly increases the workload of the post; after adopting this technical solution, there is no need to set up components such as belts, so the workload of cleaning and maintaining the belt is reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, an embodiment of the present invention provides a method for extinguishing and collecting tail coke of a top-charging coke oven, comprising:

[0029] S101, moving the coke intercepting car to a predetermined position on the coke oven side, and moving the coke quenching trolley to a predetermined position on the coke oven side;

[0030] S102, when the tail coke is output from the tail coke outlet of the coke oven, the tail coke is received by the inclined tail coke chute provided on the coke intercepting vehicle, so that the tail coke falls into the top of the tail coke chute;

[0031] S103, delivering water to the top of the tail coke chute through a high-pressure water pump, so that the tail coke is cooled and quenched, and the tail coke is made to slide from top to bottom into a coke-water separation bucket provided on the coke quenching trolley under the action of hydraulic flushing;

[0032] S104, separating the tail coke from water by means of a screen provided in the coke-water separation bucket.

[0033] In order to solve the aforementioned problems, in this application, the scraper mechanism of the prior art is no longer used to quench and deliver coke. Instead, the tail coke is received by the tail coke chute on the coke intercepting car, and then the tail coke in the tail coke chute is transferred to the coke-water separation bucket below under the action of hydraulic flushing. In this process, the red coke is extinguished and finally collected in the coke-water separation bucket. In order to adapt to the actual environment of the 6m top-loading coke oven, before work, the device to be used in this method is first designed in a split type, that is, some components are arranged on the coke intercepting car running along the top track (upper water tank, high-pressure water pump, and tail coke chute, etc.), and the other components are arranged on the coke quenching trolley running along the ground track (coke-water separation bucket, etc.). The tail coke chute can be designed as an inclined trough structure with open ends. A feed port is arranged on the top of the coke-water separation bucket for receiving the tail coke sliding down the tail coke chute (the diameter of the feed port is larger than the diameter of the bottom end of the tail coke chute). As a preferred embodiment, the tail coke chute is made of a square trough with rounded corners and back-welded, and is made of stainless steel.

[0034] During operation, after the coke guide car and the quenching car are in place (at this time, the quenching car should move to the lower side of the coke guide car, and the coke-water separation hopper should be located directly below the output end of the tail coke chute), the coke discharged from the tail coke outlet of the coke oven falls into the tail coke chute. At the same time, the high-pressure water pump sprays water into the tail coke chute. Through the scouring action of the water, the coke moves downward into the coke-water separation hopper. During the transportation process, the incandescent coke is quenched by the water, so the coke quenching and collection operations are very convenient. After entering the coke-water separation hopper, since a sieve is provided in the coke-water separation hopper and the aperture of the sieve is smaller than the size of the coke to be collected, the quenched coke and water are separated. When the coke in the coke-water separation hopper is full, it can be transferred to the supporting coke drying platform area.

[0035] Further, in step S103, the upper water tank provided on the coke guide car is used to supply water to the high-pressure water pump, that is, the water outlet of the upper water tank is connected to the water inlet of the high-pressure water pump, and the volume of the upper water tank should be determined according to the actual usage requirements.

[0036] Further, the method for quenching and collecting the tail coke of the top-charging coke oven further includes: after separating the tail coke and water through the coke-water separation hopper, the tail coke is left in the coke-water separation hopper, and the separated water is transferred to the collection tank (also provided on the quenching car) through the connecting pipeline to achieve water collection and avoid waste.

[0037] Further, the water separated from the coke-water separation hopper still contains impurities (mainly coke powder). For this reason, the method for quenching and collecting the tail coke of the top-charging coke oven further includes: purifying the water through the collection tank to obtain purified water. The specific purification form can be: a vertical partition is provided in the collection tank (the height of the partition should be limited, and its top does not touch the inner top of the collection tank), and the collection tank is partitioned to form a front chamber for coke powder precipitation and static settlement and a rear chamber for accommodating purified water; when the liquid level in the front chamber is higher than the top of the partition, the water at the top layer higher than the top of the partition overflows into the rear chamber, so that all the purified water enters the rear chamber. In subsequent operations, the purified water can be taken from the rear chamber; a sewage outlet can be provided at the bottom of the front chamber to regularly discharge the sediment.

[0038] Furthermore, the method for extinguishing and collecting tail coke of the top-loading coke oven further includes: returning water from the collecting water tank to the upper water tank in an intermittent manner to achieve the recycling of water and reduce the dependence of the upper water tank on external water supply. However, due to the relative positional relationship between the coke guide car and the coke quenching trolley during the working process not being fixed (after the coke-water separation hopper of the coke quenching trolley accumulates and stores up, the tail coke needs to be transferred to the coke cooling table area supporting the coke oven), a fixed pipeline cannot be used to connect the water return pump and the upper water tank. Therefore, in this application, a detachable pipeline is used to connect the two to avoid affecting the passage of the coke quenching trolley. Only when water return is required, the detachable pipeline is connected. In this technical solution, preferably, a water return hose for water return operation is provided. The two ends of the water return hose are respectively a water return hose fixed end and a water return hose free end. The water return hose fixed end is connected to the upper water tank. At the same time, a water return pump communicating with the rear chamber of the collecting water tank is provided on the coke quenching trolley. When water return operation is required, the water return hose free end is lowered and connected to the water return pump provided on the coke quenching trolley. Then, the stop valve at the outlet end of the water return pump is opened and the water return pump is started to convey the purified water back to the upper water tank; when water return operation is not required, the water return hose free end is disconnected from the water return pump, and the height of the water return hose free end is raised so that it is higher than the top end of the coke quenching trolley.

[0039] In addition, a filter can be provided at the water outlet of the collecting water tank so that the collecting water tank is connected to the water inlet of the water return pump through the filter. In this way, further filtration can be achieved. For example, by using a finer filter screen, the smooth water return can be further ensured and blockage can be avoided.

[0040] Furthermore, the method for extinguishing and collecting tail coke of the top-loading coke oven further includes: connecting the free end of the water return pipe and the water return pump through a clamping joint to achieve quick installation and disassembly operations between the two. The clamping joint (commonly known as a quick coupling or quick-release joint) can adopt existing technical products. It consists of two mutually matching parts. One part is connected to the free end of the water return hose, and the other part is connected to the water outlet pipeline of the water return pump. When the two parts are butted, a closed-loop water path can be formed for water return operation; when the two parts are loosened, the separation of the water return pump and the water return hose is achieved, and then the free end of the water return hose can be lifted.

[0041] Furthermore, for the convenience of operation, a hose lifting device (such as a small winch) for lifting the water return hose can be provided on the coke guide car. When water return is required, the height of the free end of the water return hose (the end connected with the clamping joint) is lifted through the hose lifting device. After the water return is completed, the connection between the water return hose and the water return pump is disconnected, and the water return hose is lifted to avoid affecting the passage of the coke quenching trolley.

[0042] Further, the method for extinguishing and collecting tail coke of the top-loading coke oven further includes: laying a chute cover plate on the tail coke chute. Through the sealing effect of the chute cover plate, the high-temperature water vapor generated by the cooling of the high-temperature red coke when encountering water in the tail coke chute can be sealed in the chute, thereby isolating the escape of water vapor and reducing the excessive loss of moisture.

[0043] Further, since the volume of the water collection tank on a single coke quenching trolley is limited, while the water demand of the upper water tank is relatively large (in a specific embodiment, the volume of a single water collection tank is about 2.5 m 3 , and the volume of the upper water tank is 8 m 3 ), therefore, in order to better improve the water collection capacity and meet the requirements of the upper water tank with as few water return times as possible, parallel connection interfaces can be reserved on the water collection tank, and then connected to the parallel connection interfaces through hoses, so as to connect the multiple water collection tanks of two coke quenching trolleys in parallel, thereby increasing the effective volume. When returning water subsequently, the water in all the water collection tanks connected in parallel can be pumped synchronously. For example, if only the water collection tank of a single coke quenching trolley is used for water storage, water needs to be returned immediately after it is full, otherwise there will be no more space for storage; while when the water collection tanks of two coke quenching trolleys store water simultaneously, the time required to fill up is doubled, and correspondingly, the interval of the water return operation can be extended, thereby reducing the working intensity.

[0044] At the same time, a liquid level display and high and low liquid level alarm devices are installed in the upper water tank, and the alarm signals are transmitted back to the control system for real-time monitoring (the low liquid level is about 2 m 3 , and the high liquid level is about 7 m 3 ), so as to avoid water shortage or overflow in the upper water tank due to excessive water volume.

[0045] In addition, in order to enable the tail coke chute to better receive the tail coke output from the tail coke outlet of the coke oven, a receiving hopper can be set on the coke guide car, and the receiving hopper is connected to the top end (or the starting end) of the tail coke chute. The diameter of the receiving hopper is larger than the width of the tail coke chute, which can better receive the tail coke and avoid spillage. During operation, the tail coke first falls into the receiving hopper and then enters the tail coke chute and moves downward. The preferred shape of the receiving hopper is a funnel-shaped structure with a rectangular top opening, and the bottom of the funnel structure is connected to the top end of the tail coke chute.

[0046] The following details the technical solution of the present application with a specific embodiment:

[0047] The structure of this specific embodiment is as Figure 2 、 Figure 3 、 Figure 4As shown, it includes a high-pressure water power device (high-pressure water pump 1) installed on the coke intercepting car 100, a tail coke chute 2, a return hose 6, a hose lifting device, and a coke-water separation bucket 3, a water collecting tank 4, a return pump 5, etc. installed on the coke quenching trolley 200. When the tail coke at the furnace head falls into the tail coke chute 2, it is cooled and quenched by the high-pressure water delivered by the high-pressure water pump 1, and is transported to the coke-water separation bucket 3 through the feed port 11 by the power provided by the high-pressure water, and the coke and water are separated in the coke-water separation bucket 3. After the coke is accumulated and stored in the coke-water separation bucket 3, it is transferred to the coke drying platform area of the coke oven. The water separated by the coke-water separation bucket 3 enters the water collecting tank 4, and after being left to stand and separate the coke powder, it can be transported back to the high-pressure water pump 1 through the return hose 6 by the return pump 5 for recycling.

[0048] By utilizing the elevation difference between the coke intercepting car 100 and the coke quenching trolley 200, a coke-water separation bucket 3 is installed on the coke quenching trolley 200 to collect coke and water, and a screen filtering device is designed in the coke-water separation bucket 3 to realize the functions of storing coke in the coke-water separation bucket and allowing water to flow into the water collecting tank 4 by gravity, thereby achieving the goal of separating coke from water.

[0049] A partition is designed in the water collecting box 4 to divide the water collecting box into a front chamber and a rear chamber. After the water is collected in the front chamber, it has a standing time to allow the coke powder to settle at the bottom of the front chamber, and the water flows into the rear chamber to achieve the purpose of separating the coke powder from the water.

[0050] The coke-water separation bucket 3 and the water collecting tank 4 are designed with storage function to realize the intermittent recovery function of coke and water, which is matched with the coke production of the 6m top-loading coke oven and solves the problem of continuous recovery affecting the operation time of the coke oven.

[0051] A hose lifting device is provided on the coke intercepting vehicle 100. When the water in the water collecting tank 4 is recovered, the return hose 6 is lowered, and the clamping joint 7 at the free end of the return hose 6 is connected to the outlet of the return pump 5, thereby forming a loop for the return operation; and when the coke oven is in normal production, the free end of the return hose 6 is lifted by the hose lifting device to eliminate the problem of the fixed return soft pipe obstructing the passage of the coke quenching trolley. After actual measurement, after the clamping joint 7 (quick joint) is provided, the quick connection or quick removal between the return hose 6 and the return pump 5 can be completed within 10 seconds, which takes much less time than ordinary clamp connection or threaded connection, greatly improving work efficiency.

[0052] The coke guide car 100 includes a frame and a traveling mechanism of the coke guide car that can run along the coke guide track. The frame is connected to the traveling mechanism of the coke guide car; the charging hopper, the upper water tank, the high-pressure water pump 1, and the tail coke chute 2 are all fixedly connected to the frame. The frame is the main structure of the coke guide car, which is welded by high-strength steel and is used to support and install other components. It needs to have sufficient strength and stiffness to withstand various loads during operation. The traveling mechanism of the coke guide car generally consists of a motor, a reducer, wheels, etc., which drives the coke guide car 100 to walk smoothly on the coke guide track to achieve accurate alignment. At the same time, a furnace door opening and closing device (driven by a hydraulic system or an electric push rod, etc., including components such as door hooks and opening and closing mechanisms) for opening and closing the coke oven door, a dust collection device (including a dust collection hood, a pipeline, a valve, and a dust suction device), etc. are also provided on the coke guide car 100, and a corresponding hydraulic system and an electrical control system are provided (to control various actions of the coke guide car 100, including the start, stop, and speed regulation of the motor, as well as the valve opening and closing of the hydraulic system, usually controlled by a PLC).

[0053] The coke quenching trolley 200 includes a vehicle body and a traveling mechanism of the coke quenching trolley that can run along the coke quenching track. The vehicle body is connected to the traveling mechanism of the coke quenching trolley; the water collection tank 4 and the return water pump 5 are both fixedly connected to the vehicle body. The vehicle body is the load-bearing part of the coke quenching trolley 200, which is welded by steel plates; the traveling mechanism of the coke quenching trolley is similar to that of the coke guide car, consisting of a motor, a reducer, wheels, etc., enabling the coke quenching trolley 200 to run accurately on the track and cooperate with the coke guide car 100 and the coke oven; a frame connection device is also provided between the vehicle body and the traveling mechanism of the coke quenching trolley to ensure reliable connection and force transmission between the two, while allowing a certain degree of relative movement to adapt to the unevenness of the track and the change of the running attitude of the vehicle; the coke quenching trolley 200 is also provided with a braking device, including components such as a brake and a brake wheel, which is used to accurately stop when the coke quenching trolley 200 runs to a designated position and to quickly brake in case of an emergency to ensure the safety of equipment and personnel; in addition, the coke quenching trolley 200 is also provided with a corresponding electrical control system to control the traveling, braking, etc. actions of the coke quenching trolley 200.

[0054] It should be noted that the high-pressure water pump 1 can be integrally designed with the upper water tank 9, so Figure 2 、 Figure 4 no separate indication of the high-pressure water pump 1 is made anymore; similarly, the return water pump 5 can also be integrally designed with the water collection tank 4, so Figure 2 、 Figure 4 no separate indication of the return water pump 5 is made anymore.
