Description

TECHNICAL FIELD

[0001] The utility model relates to the industrial dust removal equipment technical field, specifically, relate to a kind of for the high-efficiency dust suppression system of mobile coke drop car. BACKGROUND

[0002] In the coking process, each link of coke production can produce a large amount of dust, especially during the operation of the coke drop car (i.e., the equipment used to unload coke from the coke oven); the movement of the coke drop car and the unloading process of the coke can generate a large amount of particulate matter, which not only pollutes the environment, but also can harm the health of production personnel. In order to effectively control dust pollution, coking plants usually take a series of dust suppression measures; however, traditional dust suppression methods often have some defects, resulting in unsatisfactory dust control effect.

[0003] It is a common production process for coking enterprises to use a mobile material dropping trolley in the coke shed for material dropping operation. This process is usually accompanied by significant dust emissions, mainly due to the high drop between the material dropping port and the ground (usually more than 10 meters), as well as the low moisture content of the coke itself. Due to these factors, a large amount of dust is generated during the material dropping process, which spreads and diffuses with the airflow, seriously affecting the ambient air quality and not meeting the increasingly stringent environmental policy requirements.

[0004] In actual operation, the mobile material dropping trolley moves back and forth along the preset track, stops at a certain unloading port when it travels, and performs material dropping work. Since the dust generation point changes constantly with the movement of the trolley, the generated dust is not fixed at a certain position, but switches between multiple unloading ports. This makes traditional environmental protection treatment facilities, such as bag-type dust collectors, face certain limitations. Bag-type dust collectors are usually suitable for dust collection devices with fixed dust generation points, but if an independent dust collection hood is designed at each unloading port, it will not only significantly increase the construction cost of the equipment, but also affect the normal production due to limited space and installation complexity, and even may lead to a decrease in production efficiency. Therefore, how to effectively control dust in such a mobile working scenario has become an environmental protection problem that many coking enterprises need to solve urgently.

[0005] Specifically, most existing dust suppression systems of enterprises mainly use water spraying, gas atomization, etc. to reduce the dust generated during coke operation; although these methods can reduce dust diffusion to some extent, due to the limitations of water spraying amount, spraying angle, etc., they often cannot completely cover the working area of the coke drop car, or the effect is poor in strong wind and other harsh environments. In addition, traditional dust suppression equipment usually requires high energy consumption and a large amount of water resources, especially in coking production, and there are certain challenges in controlling secondary pollution to the environment.

[0006] At present, with the increasingly stringent environmental regulations and the increasing requirements of enterprises on production efficiency and safety, the existing dust suppression technology cannot meet the needs of the industry. Therefore, how to design a mobile coking car dust suppression system with high dust suppression effect, low energy consumption, strong adaptability and easy maintenance has become a technical problem to be solved in the coking industry. Such a system not only can effectively reduce dust pollution, protect the environment, but also can ensure the safety of the production process, improve the health level of the working environment, and reduce the operating cost.

[0050] Embodiment 1

[0051] As shown in Figs. 1-6 The present embodiment discloses an efficient dust suppression system for moving coke drop cars, which comprises a coke drop car 1, a guide rail 2, a double-fluid dry fog device 3, a water storage tank 4 and a gas source 5. The coke drop car 1 is arranged on the guide rail 2 and can move along the length direction of the guide rail 2. A drop area for the coke drop car 1 is also arranged at intervals below the guide rail 2. The drop area is provided with the double-fluid dry fog device 3. The double-fluid dry fog device 3 is communicated with the water storage tank 4 and the gas source 5 through pipelines.

[0052] The drop area of the guide rail 2 is also provided with a sensing device. The connection positions of the water storage tank 4 and the gas source 5 with the pipelines are provided with control switches 6. The sensing device is electrically connected with the control switches 6 for the water storage tank 4 and the gas source 5.

[0053] In operation, the water storage tank 4 and the gas source 5 are started first. Then, it is checked whether the pressure of the booster pump 7 and the gas storage tank 10 is within the normal range. Subsequently, the control switches 6 are turned on. The water filter 8 and the dry fog host 9 start to operate, ensuring that the fluid in the water pipe and the gas pipe is smooth.

[0054] Then make the coke car 1 along the guide rail 2 moves, in every 1 meter interval around the unloading site on the guide rail 2 is arranged 1 double fluid universal joint assembly, a total of 8 unloading sites 8 subarea, each area is installed with travel switch, when the coke car 1 enters this area touches travel switch combination material flow sensor signal, open the double fluid universal joint assembly of this area, carry out spray dust suppression, the trolley leaves this area, will close this area dust suppression;Can be through the inductive signal control car hopper 101 stay in the guide rail 2 unloading area, slide cover opening leak hole, make the coke coal in the car hopper 101 drop;

[0055] When the coke coal in the coke car 1 is unloaded, the inductive device sends a signal to the control switch 6, and the double fluid dry fog device 3 is started. Water and gas are respectively introduced into the liquid channel 301 and the gas channel 302 of the double fluid dry fog device 3 through the pipeline, and high-efficiency mixing is carried out in the mixing channel 303 to form dry fog. The adjusting ring 304 controls the flow of the mixing channel 303 according to the demand, and adjusts the atomization degree of the dry fog to cover the unloading area.

[0056] The system monitors the fluid pressure and gas flow in the pipeline in real time through the gas measuring device 11 and the pressure gauge, to ensure the stability of the spray effect. The double fluid dry fog device 3 controls the opening and closing of the check valve 12 through the bypass port, to prevent the backflow of liquid or gas in the pipeline and ensure the safety of operation.

[0057] When the coke car 1 unloads, the coke car 1 leaves the unloading area, the inductive device stops sending signals, the slide cover closes the leak hole, the double fluid dry fog device 3 stops running, the booster pump 7 and the gas storage tank 10 enter standby state, the double fluid dry fog device 3 closes the check valve 12 through the bypass port, and the system enters standby mode until the next cycle of unloading.

[0058] As a specific embodiment, the double fluid dry fog device 3 is composed of a plurality of double fluid nozzles, and each double fluid nozzle includes a liquid channel 301, a gas channel 302, a mixing channel 303 and an adjusting ring 304. The liquid channel 301 and the gas channel 302 are arranged inside the double fluid nozzle. One end of the mixing channel 303 is in communication with the liquid channel 301 and the gas channel 302, and is used for mixing the gas and the liquid to form a mixed fluid. The adjusting ring 304 is arranged in the mixing channel 303, and is used for adjusting the flow of the mixed fluid in the mixing channel 303.

[0059] The liquid channel 301 is connected to the water storage tank 4 through a water pipe, and the gas channel 302 is connected to the gas source 5 through a gas pipe.

[0060] A one-way valve is arranged at the connection between the liquid channel 301 and the mixing channel 303, and a one-way valve is also arranged at the connection between the gas channel 302 and the mixing channel 303.

[0061] In specific work, the booster pump 7 of the water storage tank 4 is started to ensure that the pressure and water quality of the water flow meet the requirements. At the same time, the gas source 5 is started to ensure that the gas flow and pressure reach the working standard; then the control switch 6 is started, the valve of the water pipe and the gas pipe to the double-fluid dry fog device 3 is opened to provide liquid and gas for the spray head;

[0062] At this time, the moving drop car 1 moves along the guide rail 2, the sliding cover plate at the bottom of the car hopper 101 is electrically connected with the sensing device, ensuring that the movement trajectory of the drop car 1 is monitored in real time, and when the drop car 1 reaches the specified drop area, the sensing device sends a signal to the control system to activate the double-fluid dry fog device 3 and start the spraying function.

[0063] Specifically, when the liquid and gas enter the double-fluid spray head, they flow into the mixing channel 303 of the spray head through the liquid channel 301 and the gas channel 302 respectively; in the mixing channel 303, the gas and the liquid are fully mixed to form an atomized fluid; by rotating the adjusting ring 304, the flow of the fluid in the mixing channel 303 can be adjusted, and thus the atomization effect and density of the spray can be adjusted; one-way valves are arranged at the connection between the liquid channel 301 and the gas channel 302 and the mixing channel 303 respectively to prevent backflow of the liquid and the gas, ensuring stable operation of the system; the whole system is automatically controlled through intelligent modules such as sensing devices, control switches and valves, and the whole process from the drop car reaching the specified position to the spraying stopping does not require manual intervention, improving the work efficiency and reducing the operation complexity.

[0064] Specifically, the spray head of the double-fluid dry fog device adopts a liquid and gas mixed spraying technology, which can produce extremely fine water mist particles. These tiny water droplets can quickly absorb and condense dust particles in the air, thereby capturing the dust generated in the drop area, inhibiting the spread of dust, and rapidly reducing the dust concentration, thereby effectively improving the working environment and protecting the health of workers. When the drop car 1 leaves the drop area, the sensing device detects that the car hopper 101 has left, and the system automatically turns off the spraying function of the double-fluid dry fog device 3 to stop resource consumption.

[0065] Specifically, the pressure gauge and the gas measuring device 11 are used to monitor the flow and pressure of the gas and liquid in the system in real time, ensuring that the system operates in the best state; the system uses one-way valves and check valves 12 to prevent backflow of the fluid, maintaining one-way flow of the gas and liquid inside the system, thereby effectively avoiding damage to the equipment caused by reverse pressure of the liquid or gas, and improving the safety and stability of the system.

[0066] As a specific embodiment, the drop car 1 includes a car hopper 101 and a control car head 102; the control car head 102 is connected with the car hopper 101 and is used to control the movement speed; a leakage hole is arranged at the bottom of the car hopper 101, and a sliding cover plate is arranged on the leakage hole and is electrically connected with the sensing device;

[0067] The control head 102 is provided with an induction block 103, which is electrically connected when close to the induction device of the guide rail 2.

[0068] When the system is initialized, the electric control system of the control head 102 and the car 101 is started, ensuring that the car is stably connected with the control head 102, the circuit is unobstructed, and the induction device and the sliding cover plate are normally working; the induction device is self-checked at the start, ensuring that the induction block 103 is normally connected with the induction device on the guide rail 2, and the electric control system of the sliding cover plate is normally working.

[0069] Specifically, the control head 102 controls the movement speed of the coking car through the connection with the car 101. According to the operation requirements, the control head 102 adjusts the speed to drive the car 101 to move along the guide rail 2. The system adjusts the movement speed according to the actual working condition to adapt to different working condition requirements.

[0070] The leakage hole at the bottom of the car 101 is controlled by the sliding cover plate, which is electrically connected with the induction device. When the induction device sends a signal, the sliding cover plate automatically opens or closes to control the opening of the leakage hole, realizing accurate material dropping control.

[0071] Specifically, when the induction block 103 is close to the induction device of the guide rail 2, an electric signal is transmitted to the control system, which identifies the current position and automatically adjusts.

[0072] When the induction block 103 is close to the induction device on the guide rail 2, a signal is transmitted to the system to automatically adjust the movement of the car 101 or start other additional devices (such as a dry fog device); at the same time, the sliding cover plate adjusts the opening and closing state of the leakage hole according to the system control signal.

[0073] When the car 101 moves to the preset material dropping area, the sliding cover plate automatically opens to allow the coking coal to drop through the leakage hole to the ground; at this time, the induction device controls the double-fluid dry fog device 3 or other dust suppression devices to start to suppress dust.

[0074] When the coking car completes the material dropping task, the car 101 leaves the material dropping area, and the electrical connection of the induction block 103 with the induction device on the guide rail 2 is stopped; the system automatically closes the sliding cover plate and stops the auxiliary operation such as water mist spraying.

[0075] Example 2

[0076] As Figs. 1-6As shown, the embodiment discloses a high-efficiency dust suppression system for moving coke drop car, which comprises a coke drop car 1, a guide rail 2, a double-fluid dry fog device 3, a water storage tank 4 and a gas source 5; the coke drop car 1 is arranged on the guide rail 2 and can move along the length direction of the guide rail 2, and a drop area for the coke drop car 1 is also arranged below the guide rail 2 at intervals, and the drop area is provided with the double-fluid dry fog device 3, and the double-fluid dry fog device 3 is communicated with the water storage tank 4 and the gas source 5 through pipelines respectively.

[0077] The drop area of the guide rail 2 is also provided with an induction device, and the connection positions of the water storage tank 4 and the gas source 5 with the pipelines are provided with control switches 6, and the induction device is electrically connected with the control switches 6 for the water storage tank 4 and the gas source 5.

[0078] As a specific embodiment, the water pipeline of the double-fluid dry fog device 3 is provided with a booster pump 7, a water filter 8 and a dry fog host 9, and the gas pipeline of the double-fluid dry fog device 3 is provided with a gas storage tank 10 and a gas measuring device 11.

[0079] The water pipeline and the gas pipeline between the control switch 6 and the double-fluid dry fog device 3 are both provided with check valves 12.

[0080] Before the system is started, the booster pump 7 in the water storage tank 4 is started first to ensure that the pressure of the water flow reaches the working requirement. At the same time, the water filter 8 is started to filter the impurities in the water source and ensure that the water quality entering the double-fluid dry fog device 3 is clean; the dry fog host 9 is connected with the water pipeline to wait for receiving the water flow and processing to generate dry fog.

[0081] Specifically, the gas source 5 is started and the gas pressure of the gas storage tank 10 is checked to ensure that the gas source 5 can stably supply gas; the gas measuring device 11 monitors the pressure and flow of the gas source 5 in real time to ensure that the gas supply meets the working requirement, and the pressure monitoring function of the booster pump 7 and the gas measuring device 11 ensures that the system works in the best state, the operator can understand the system state in real time, and timely adjusts the working parameters to ensure the effect and efficiency of each spraying operation.

[0082] Specifically, the booster pump 7 provides high-pressure water flow to the dual-fluid dry fog device 3 through the water pipe, the water filter 8 filters the water source in real time to prevent impurities from entering the system and ensure the stability of the water flow and the dry fog effect. The water flow reaches the liquid channel 301 of the dual-fluid nozzle through the pipeline, and then the water and the gas enter the mixing channel 303 through the liquid channel 301 and the gas channel 302 respectively. In the mixing channel 303, the water and the gas are efficiently mixed to form atomized fluid, which is sprayed through the nozzle. The booster pump 7 and the gas storage tank 10 in the system work together to ensure that water and gas can be quickly provided during peak demand, avoiding energy waste. Through real-time airflow and water flow monitoring and control, the system can adjust the water and gas supply according to actual demand, achieving optimal use of resources. Due to the small size of dry fog particles, they can effectively adsorb and wrap dust particles in the air. Through collision, coagulation and gravity settling, dust particles are agglomerated and enlarged, eventually falling to the ground or collecting device, thereby achieving efficient dust suppression.

[0083] Specifically, check valves 12 are provided at the connection between the water pipe and the gas pipe to ensure that the water flow and the gas flow can only flow in one direction, preventing backflow and avoiding water or gas source 5 from flowing back to the water storage tank 4 or gas source 5, thereby improving the safety and stability of the system.

[0084] As a specific embodiment, the induction block 103 is electrically connected when it is close to the induction device of the guide rail 2, thereby controlling the drop hole of the car hopper 101 to stay in the drop area of the guide rail 2, and controlling the coking coal in the car hopper 101 to drop while the double-fluid dry fog device 3 is turned on for dry fog dust suppression.

[0085] Specifically, when the car hopper 101 passes through the guide rail 2, the induction block 103 is close to the induction device of the guide rail 2, which will trigger an electrical signal in real time. After the induction device identifies the position of the car hopper, it immediately transmits the signal to the control system to start the drop hole control and spraying system of the car hopper 101. According to the signal of the induction device, the sliding cover plate at the bottom of the car hopper 101 is automatically opened to allow the coking coal in the car hopper 101 to drop through the drop hole. The coking coal in the car hopper 101 drops through the drop hole, and the time and amount of dropping are accurately controlled to avoid unnecessary waste. When the coking coal drops to the ground, the induction device triggers the control system to start the dual-fluid dry fog device 3. The atomized water and gas are mixed and then sprayed through the spraying equipment to timely suppress the dust generated by the dropping coking coal. The system adopts modular design and is easy to operate, and the induction block 103 and the spraying equipment are easy to check and maintain. At the same time, the automation function of the system reduces the need for manual intervention, making the daily operation and maintenance of the equipment more convenient.

[0086] Example 3

[0087] As Figs. 1-6As shown, the embodiment discloses a high-efficiency dust suppression system for a mobile coke drop car, which comprises a coke drop car 1, a guide rail 2, a double-fluid dry fog device 3, a water storage tank 4 and a gas source 5; the coke drop car 1 is arranged on the guide rail 2 and can move along the length direction of the guide rail 2, and a drop area for the coke drop car 1 is further arranged at intervals below the guide rail 2, and the drop area is provided with the double-fluid dry fog device 3; the double-fluid dry fog device 3 is communicated with the water storage tank 4 and the gas source 5 through pipelines respectively.

[0088] The drop area of the guide rail 2 is further provided with a sensing device, and the water storage tank 4 and the gas source 5 are electrically connected with the control switch 6 at the connection position of the pipelines.

[0089] As a specific embodiment, the dry fog host 9 is further connected with the bypass port of the check valve 12 through a pipeline, for controlling the opening and closing of the check valve 12.

[0090] A pressure gauge is arranged on the pipeline of the booster pump 7 and the water filter 8.

[0091] When the system is initialized, the booster pump 7 is started to ensure that the pressure of the water flow reaches the working requirement; at the same time, the water filter 8 is started to ensure that the water source is clean and avoid impurities entering the system; the dry fog host 9 is connected with the booster pump 7, the check valve 12 and the bypass port thereof through a pipeline, for preparing to receive the water source and the gas source 5.

[0092] Specifically, the check valve 12 is arranged at the connection position of the water pipeline and the gas pipeline, to ensure that the liquid and the gas can only flow in one direction and prevent backflow, and the bypass port of the dry fog host 9 is connected with the pipeline, to control the opening and closing of the check valve 12 through the pipeline.

[0093] In the normal working state, the check valve 12 allows the liquid and the gas to flow in one direction; when the system appears abnormal or pipeline maintenance is needed, the bypass port of the dry fog host 9 controls the closing of the check valve 12, to prevent the liquid and the gas from backflowing to other parts of the system.

[0094] After the task is completed, the control switch 6 stops the supply of the water source and the gas source 5, and the operation of the booster pump 7, the water filter 8 and the dry fog host 9; the dry fog host 9 controls the check valve 12 to close through the bypass port, to ensure that the liquid and the gas in the system do not backflow, thereby effectively preventing the backflow of the liquid and the gas, ensuring the stability and safety of the water source and the gas source 5 system, and controlling the opening and closing of the check valve 12 through the bypass port, to ensure that the fluid does not backflow when abnormality or shutdown occurs, preventing equipment damage.

[0095] As a specific embodiment, the adjusting ring 304 is synchronously connected with the shell ring of the double-fluid nozzle, the opening degree of the adjusting ring 304 can be controlled by rotating the shell of the double-fluid nozzle, thereby controlling the flow of the mixed fluid in the adjusting and mixing channel 303, and thereby adjusting the atomization degree of the double-fluid nozzle.

[0096] Specifically, the operator can accurately control the flow of mixed fluid by rotating the shell, thereby adjusting the degree of atomization; the fineness and intensity of the spray can be flexibly adjusted according to different working requirements.

[0097] In different working environments, different intensities of atomization effect may be required, for example, a large amount of spray may be required for large-scale spraying, and smaller atomized particles may be required for fine operation; the spray effect can be adjusted according to actual requirements through the rotation adjustment ring 304, so that the system can maintain high efficiency in various working conditions.
