Description

Technical Field

[0001] This utility model belongs to the technical field of rinsing devices, specifically an automatic rinsing device for a needle-shaped coke cutter water tank. Background Technology

[0002] Traditional needle coke delayed coking units often suffer from coke powder accumulation in the coke cutting water tank due to the production process. The tank cannot be flushed in time, which has a great impact on safe production. It is easy to cause blockage of the reversing valve on the conveying pipe leading to the next process during coke cutting, resulting in frequent start-stop of the high-pressure water pump, which seriously increases the problem of power consumption, and it is also easy to cause process accidents. Traditional tank cleaning is done manually, which takes a long time and requires a lot of manpower, resulting in high actual costs. Therefore, there is an urgent need to design an automatic flushing device for needle-shaped coke cutting tanks to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic rinsing device for needle coke cutting water tanks, which solves the problem that the needle coke delayed coking device mentioned above will cause the reversing valve on the conveying pipe of the next process to be blocked due to the accumulation of coke powder during the coke cutting process. At the same time, the blockage will also cause the high-pressure water pump to start and stop frequently, which will seriously increase the power consumption and may also cause process accidents. Traditional manual tank cleaning is time-consuming and has high labor costs.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic rinsing device for a needle-shaped coke cutting water tank, including a water collection tank, a coke cutting water tank, and a rinsing assembly. The water collection tank is provided with a clean water receiving chamber and a wastewater receiving chamber. The upper part of the coke cutting water tank is connected to the clean water receiving chamber through a circulation pipe, and both sides of the bottom of the tank are connected to the wastewater receiving chamber through drain pipes. The flushing assembly includes two sets of spray coil assemblies, several flushing pipes, and a first conveying pipe. The two sets of spray coil assemblies are staggered vertically along the inner circumference of the coke-cutting water tank, and each set of spray coil assemblies includes several spray coils, each of which is equipped with several nozzles. Several flushing pipes are respectively installed on the outer wall of the coke cutting water tank, and the inner ends of the flushing pipes are respectively connected to the corresponding spray coils. The outer ends are connected to several liquid inlet pipes, and the liquid inlet pipes are connected to the circulation pipes through pipes. One end of the first conveying pipe is connected to the coke removal system, and the other end is connected to the middle of the liquid inlet pipes through two parallel pipes.

[0005] Furthermore, the number of the plurality of injection coils is three, and the three injection coils are respectively staggered vertically along the inner circumference of the left or right half of the coke-cutting water tank.

[0006] Furthermore, a second conveying pipe is connected to the bottom of the coke-cutting water tank, the second conveying pipe is connected to the first conveying pipe, and a water pump is installed on the second conveying pipe.

[0007] Furthermore, each of the aforementioned injection coils is arc-shaped.

[0008] Furthermore, a flushing valve is provided on the liquid inlet pipe.

[0009] Furthermore, a circulation pump is installed on the circulation pipeline.

[0010] Furthermore, the sewage pipe is equipped with a sewage valve and a visual observation valve at intervals.

[0011] The beneficial effects of this utility model are as follows: The automatic flushing device for the coking water tank of this utility model can introduce water from both sides of the coking water tank through the circulation pipe and the liquid inlet pipe, and remove the coking powder accumulated on the tank wall by layered flushing. In addition, the clean water receiving chamber circulates water into the coking water tank through the circulation pipe to flush the residue at the bottom of the coking water tank. Finally, the cleaned coking powder is transported to the sewage receiving chamber through the sewage discharge pipe. This prevents the risk of blockage of the reversing valve on the conveying pipe leading to the next process during coking, reduces the number of times the high-pressure water pump is frequently started and stopped, effectively reduces the power consumption of the needle coke delayed coking device, and solves the problem of increased cost caused by the time-consuming and labor-intensive manual tank cleaning. It also solves the problem that the existing flushing mechanism cannot completely remove the accumulated coking powder in the coking water tank. The arrangement of each spray coil group is achieved by staggering the two spray coil groups along the inner circumference of the left and right halves of the coke-cutting water tank, respectively, and by using an arc design, so as to perform form-based cleaning on the opposite inner circumference, thereby improving the rinsing cleanliness rate. The arc shape of the spray coils allows the liquid sprayed from a group of three spray coils to form a fan-shaped flushing surface, automatically flushing the coke cutting water tank, greatly improving the flushing effect and reducing the workload of personnel. The installation of drain valves and visual observation valves on the drain pipes allows for observation of the conditions inside the drain pipes, preventing scale buildup and improving the operational stability of the needle coke delayed coking unit.

Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] In one specific embodiment of this utility model, such as Figure 1-2 As shown, an automatic flushing device for a needle coke cutting water tank is disclosed, including a water collection tank 1, a cutting water tank 2, and a flushing assembly 3. The water collection tank 1 is provided with a clean water receiving chamber 11 and a wastewater receiving chamber 12. The upper part of the cutting water tank 2 is connected to the clean water receiving chamber 11 through a circulation pipe 4, and both sides of the bottom are connected to the wastewater receiving chamber 12 through drain pipes 5. A circulation pump 9 is provided on the circulation pipe 4, and a drain valve 10 and a visual observation valve 13 are provided at intervals on the drain pipe 5. The drain valve 10 is a solenoid valve. The setting of the drain valve 10 and the visual observation valve 13 on the drain pipe 5 allows the condition inside the drain pipe 5 to be observed through the visual observation valve 13, so as to avoid the problem of scale accumulation in the drain pipe 5 and improve the stability of the needle coke delayed coking unit operation.

[0016] The rinsing assembly 3 includes two sets of spray coil assemblies 31, several rinsing pipes 32, and a first conveying pipe 33. The two sets of spray coil assemblies 31 are staggered vertically along the inner circumference of the coke cutting water tank 2, and each set of spray coil assemblies 31 includes several spray coils 311, and each spray coil 311 is equipped with several nozzles 3111. Several flushing pipes 32 are respectively installed on the outer wall of the coke cutting water tank 2, and the inner ends of the several flushing pipes 32 are all corresponding to the corresponding spray coils 311. The outer ends are connected to several liquid inlet pipes 34. The several liquid inlet pipes 34 are all connected to the circulation pipe 4 through pipes. A flushing valve 8 is provided on the liquid inlet pipe 34. The flushing valve 8 is a solenoid valve.

[0017] The aforementioned automatic flushing device for the coke cutting water tank can remove the accumulated coke powder on the tank wall by using a layered flushing method after water is introduced from both sides. In addition, the clean water receiving chamber 11 circulates water into the coke cutting water tank 2 through the circulation pipe 4 to flush away the residue at the bottom of the coke cutting water tank 2. Finally, the cleaned coke powder is transported to the sewage receiving chamber 12 through the sewage discharge pipe 5. This prevents the risk of blockage of the reversing valve on the conveying pipe leading to the next process during coke cutting, reduces the number of times the high-pressure water pump is frequently started and stopped, effectively reduces the power consumption of the needle coke delayed coking unit, and solves the problem of increased costs caused by the time-consuming and labor-intensive manual tank cleaning. It also solves the problem that the existing flushing mechanism cannot completely remove the accumulated coke powder in the coke cutting water tank 2.

[0018] One end of the first conveying pipe 33 is connected to the decoking system 36, and the other end is connected to the middle of several liquid inlet pipes 34 through two parallel pipes.

[0019] The number of spray coils 311 is three. The three spray coils 311 are staggered vertically along the inner circumference of the left or right half of the coke cutting water tank 2. Each spray coil 311 is arc-shaped. The arc shape of the spray coils 311 allows the liquid sprayed by the three spray coils 31 to form a fan-shaped flushing surface, which automatically flushes the coke cutting water tank 2, greatly improving the flushing effect and reducing the workload of personnel.

[0020] The arrangement of each set of spray coils 31 is achieved by staggering the two sets of spray coils 31 along the left and right halves of the inner circumference of the coke-cutting water tank 2, respectively, and by using an arc design, so as to perform form-based cleaning on the opposite inner circumference, thereby improving the rinsing cleanliness rate.

[0021] The bottom of the coke cutting water tank 2 is connected to a second conveying pipe 6, which is connected to the first conveying pipe 33. A water pump 7 is installed on the second conveying pipe 6.

[0022] The working process of this utility model: Coking is an intermittent operation. After coking is completed, the coking water tank 2 and the coking removal system 36 need to be rinsed. Each rinsing time is six hours. The circulation pump 9 on the circulation pipe 4 is turned on, and a portion of the clean water in the clean water receiving chamber 11 of the water collection tank 1 is pumped into the pipe connected to the circulation pipe 4. Then, the rinsing valve 8 on each liquid inlet pipe 34 is opened. The rinsing valve 8 is a solenoid valve. The control unit controls the opening of the rinsing valve 8, the valve on the first conveying pipe 33, and the valve on the second conveying pipe 6 near the coking removal system 36. Clean water is transported from the pipes to several liquid inlet pipes 34 and from several liquid inlet pipes 34. Water is delivered to the corresponding flushing pipe 32. Each flushing pipe 32 delivers water to the corresponding spray coil 311. Water is sprayed from the nozzles 3111 on the spray coil 311, which are staggered on the left and right sides of the coke cutting water tank 2, onto the opposite peripheral walls. The sprayed water flows out in a fan shape to remove the coke powder accumulated on the opposite peripheral walls. The condition inside the drain pipe 5 can be observed at any time through the observation valve 13. When there is a lot of dirt, the drain valve 10 is opened by the control unit, and the sewage is discharged into the sewage receiving chamber 12 through the drain pipe 5 to complete the cleaning of the inner wall of the coke cutting water tank 2. Meanwhile, the water in several liquid inlet pipes 34 is transported through the first conveying pipe 33 and then through the second conveying pipe 6 to the coking removal system 36 to clean the coking removal system 36. The other part is pumped into the coke cutting water tank 2 through the circulation pipe 4, and water can be circulated into the coke cutting water tank 2 to remove the coke powder accumulated at the bottom of the coke cutting water tank 2. The condition of the sewage pipe 5 can be observed at any time through the visual pipe observation valve 13. When there is a lot of dirt, the sewage valve 10 is opened by the control unit, and the sewage is discharged into the sewage receiving chamber 12 through the sewage pipe 5 to complete the cleaning of the bottom of the coke cutting water tank 2. When coke cutting is required, the coke cutting time is usually 12 hours. Open the two valves on the second conveying pipe 6, and the water in the coke cutting water tank 2 will be transported to the coke removal system 36 for water supply through the water pump 7 on the bottom of the second conveying pipe 6.
