Description

Technical Field

[0001] The present application relates to the technical field of raw coal storage equipment, and in particular to a raw coal bunker with a compartment structure. Background Art

[0002] The raw coal bunker is an important facility in power engineering for storing raw coal, coal slime and other granular materials in thermal power plants. During the operation of thermal power generating units, the coal stored in the raw coal bunker is transported to the coal mill through the coal feeder, and the coal mill turns the coal into coal powder for use in the generating units.

[0003] In order to reduce production costs, the coal used by generator sets has gradually changed, with high-calorific coal and economic coal used alternately. During the operation of existing generator sets, when changing the type of coal, the original coal in the raw coal bunker is usually emptied, and the newly replaced coal is injected before supplying coal to the coal feeder. During this process, the coal supply is interrupted and the generator set is in a shutdown state. After the coal is replaced and restarted, it is difficult to meet the needs of the generator set to quickly connect to the load. Summary of the invention

[0004] In order to meet the need for rapid load connection of a generator set, the present application provides a raw coal bunker with a sub-bin structure.

[0005] The present application provides a raw coal bunker with a compartment structure that adopts the following technical solution:

[0006] A raw coal bunker with a divided bunker structure, comprising: a coal feeding bunker, a coal storage bunker and two sets of detection devices; the coal feeding bunker and the coal storage bunker are integrally arranged coaxially, the coal feeding bunker is connected with the coal storage bunker, and the coal feeding bunker is located on the top of the coal storage bunker;

[0007] The coal inlet bunker is configured as a conical hollow structure, and the diameter of the coal inlet bunker gradually increases from one end close to the coal storage bunker to one end far away from the coal storage bunker; the coal storage bunker is configured as a conical hyperbolic structure, and the diameter of the coal storage bunker gradually decreases from one end close to the coal inlet bunker to one end far away from the coal inlet bunker;

[0008] The detection device is fixedly arranged in the coal storage bin, and the detection device is used to detect the state parameters of the coal in the coal storage bin;

[0009] A partition is vertically arranged in the coal storage bin, and two side edges of the partition are fixedly connected to the inner wall of the coal storage bin;

[0010] The partition separates the coal storage bin into a first coal storage section and a second coal storage section, and the first coal storage section and the second coal storage section are symmetrically arranged with respect to the partition; high-calorific coal is arranged in the first coal storage section, and economic coal is arranged in the second coal storage section;

[0011] A coal feeding port is provided below the coal storage bin, and a coal feeder is connected to the coal feeding port.

[0012] By adopting the above technical scheme, a partition is arranged in the coal storage bin, and the partition divides the coal storage bin into a first coal storage section and a second coal storage section, so that high-calorific coal and economic coal enter the coal storage bin through the coal inlet bin and are stored in the first coal storage section and the second coal storage section respectively. When the generator set is running, according to the different combustion needs of the boiler, the economic coal or high-calorific coal flows to the coal feeder through the coal feeding port, and the coal feeder transports the corresponding economic coal or high-calorific coal to the pulverizer, so as to quickly replace the type of coal required by the generator set, so that the unit can quickly take on the load and improve the power generation efficiency of the unit; at the same time, the coal storage bin is set to a conical hyperbolic structure. As the coal flows from the top of the coal storage bin to the bottom of the coal storage bin, the inclination angle of the bin wall gradually increases, which makes the gravity component of the coal along the bin wall gradually increase, while the extrusion component of the gravity on the bin wall gradually decreases, so as to avoid the coal from adhering to the inner wall of the coal storage bin, thereby improving the smoothness of the flow of coal in the coal storage bin.

[0013] In a specific embodiment, the top height of the partition is lower than the bottom height of the coal storage bin, and the bottom height of the partition is higher than the bottom height of the coal storage bin;

[0014] The thickness of the partition gradually decreases from one end close to the coal inlet bin to one end far away from the coal inlet bin.

[0015] By adopting the above technical solution, the thickness of the partition gradually decreases from one end close to the coal inlet bin to the end far from the coal inlet bin, which is convenient for improving the fluidity of the coal in the first coal storage section and the second coal storage section, and further convenient for avoiding the accumulation of coal in the first coal storage section and the second coal storage section and causing blockage.

[0016] In a specific possible implementation scheme, it also includes a first sealing plate and a second sealing plate, wherein the first sealing plate is fixedly arranged above the first coal storage part, and the first sealing plate is arranged in a semi-conical shape, one end of the first sealing plate is fixedly connected to the inner wall of one end of the first coal storage part close to the coal inlet bin, and the other end is fixedly connected to the top of the partition; a first feed port is provided on the first sealing plate, and high-heat coal enters the first coal storage part through the first feed port; a first flap door is fixedly arranged on the first sealing plate, and the first flap door is used to realize the opening and closing of the first feed port;

[0017] The second sealing plate is fixedly arranged above the second coal storage section, and the second sealing plate is arranged in a semi-conical shape, one end of the second sealing plate is fixedly connected to the inner wall of one end of the second coal storage section close to the coal feeding bin, and the other end is fixedly connected to the top of the partition; the second sealing plate and the first sealing plate are symmetrically arranged about the partition; a second feed port is opened on the second sealing plate, and economic coal enters the second coal storage section through the second feed port; a second flap door is fixedly arranged on the second sealing plate, and the second flap door is used to realize the opening and closing of the second feed port.

[0018] By adopting the above technical solution, when adding high-heat coal to the first coal storage section, the first flap door is opened, and the high-heat coal slides down along the inclined first sealing plate and enters the first coal storage section through the first feeding port. The arranged first sealing plate separates the coal feeding bin from the first coal storage section and provides an installation basis for the first flap door, so as to facilitate the coal injection operation to the first coal storage section. At the same time, when adding economic coal, the first flap door is closed and the first coal storage section is blocked to prevent the economic coal from entering the first coal storage section, resulting in the mixing of coal materials in the first coal storage section, which affects the coal injection operation to the first coal storage section. The combustion efficiency is affected; when economic coal is added to the second coal storage section, the second flap door is opened, and the economic coal slides down along the inclined second sealing plate and enters the second coal storage section through the second feeding port. The arranged second sealing plate separates the coal feeding bin from the second coal storage section and provides an installation basis for the second flap door at the same time, so as to facilitate the coal injection operation into the second coal storage section; at the same time, when high-heat coal is added, the second flap door is closed and the second coal storage section is blocked to prevent high-heat coal from entering the second coal storage section, which would cause the coal materials in the second coal storage section to be mixed and generate energy waste.

[0019] In a specific possible implementation scheme, it also includes a first bottom plate and a second bottom plate, wherein the first bottom plate is horizontally arranged in the inner cavity of the first coal storage part near the bottom end, and the first bottom plate is fixedly connected to the inner wall of the first coal storage part at one end, and fixedly connected to the bottom of the partition at the other end;

[0020] The second bottom plate is horizontally arranged in the inner cavity of the second coal storage section near one end of the bottom, and one end of the second bottom plate is fixedly connected to the inner wall of the second coal storage section, and the other end is fixedly connected to the bottom of the partition.

[0021] By adopting the above technical solution, the first bottom plate is set to separate the first coal storage section from the coal feeding port, and the second bottom plate is set to separate the second coal storage section from the coal feeding port, which facilitates coal storage in the first coal storage section and the second coal storage section to avoid coal leakage.

[0022] In a specific implementation scheme, the first bottom plate and the second bottom plate are both provided with a gate valve, the gate valve passes through the side wall of the first coal storage part or the second coal storage part, and the end of the gate valve is fixedly connected to the partition; the gate valve is used to achieve communication between the first coal storage part and the coal feeding port and communication between the second coal storage part and the coal feeding port;

[0025] By adopting the above technical scheme, the two gate valves respectively block the first bottom plate and the second bottom plate. When it is necessary to burn high-temperature coal, the gate valve under the first coal storage section is opened, and the gate valve under the second coal storage section is closed. The high-temperature coal falls from the bottom of the first coal storage section and flows to the coal feeder through the coal feeding port. The coal feeder transports the high-temperature coal to the coal mill for processing; the two gate valves are set up to facilitate opening the corresponding gate valve according to different coal demand, and quickly change the coal type, so that the unit can quickly connect the load and improve the power generation efficiency of the unit; when it is necessary to open the gate valve, force is applied to the runner to rotate the runner, and the runner drives the screw rod to rotate, and the screw rod moves along the axis direction of the nut. While moving, the screw rod drives the gate plate to slide in the frame, so that the first coal storage section or the second coal storage section is connected with the coal feeding port, which is convenient for transferring coal from the coal feeding port to the coal feeder, and convenient for quickly loading coal.

[0026] In a specific implementation scheme, the detection device includes a temperature sensor, a humidity sensor and two guided wave radar level meters; the two guided wave radar level meters are respectively fixedly arranged in the first coal storage section and the second coal storage section;

According to different coal demand requirements, multiple partitions 21 can be set in the coal storage bin 2, and the number of sealing plates, bottom plates, and corresponding flap doors and gate valves 29 can be increased in turn to facilitate separate storage of various types of coal.

[0057] The implementation principle of the raw coal bunker with a compartment structure of the present application is as follows: high-temperature coal and economic coal enter the coal storage bunker 2 through the coal inlet bunker 1, and are stored in the first coal storage section 22 and the second coal storage section 23 respectively. When high-temperature coal is added, the first flap door 2511 is opened and the second flap door 2611 is closed to prevent the high-temperature coal from entering the second coal storage section 23; when economic coal is added, the first flap door 2511 is closed and the second flap door 2611 is opened to prevent the economic coal from entering the first coal storage section 22; two gate valves 29 respectively block the bottom ends of the first coal storage section 22 and the second coal storage section 23. When high-temperature coal needs to be burned, the gate valve 29 under the first coal storage section 22 is opened, and the gate valve 29 under the second coal storage section 23 is closed, and the high-temperature coal falls from the bottom of the first coal storage section 22 and flows to the coal feeder through the coal feeding port 24. The coal feeder feeds the high-temperature coal Transport to the coal mill for processing; when it is necessary to burn economic coal, the gate valve 29 under the second coal storage section 23 is opened, and the gate valve 29 under the first coal storage section 22 is closed, and the economic coal falls from the bottom of the second coal storage section 23 and flows to the coal feeder through the coal feeding port 24, and the coal feeder transports the economic coal to the coal mill for processing; when adjusting the opening of the gate valve 29, first apply force to the runner 295 to rotate the runner 295, and the runner 295 drives the screw rod 293 to rotate, and the screw rod 293 moves along the axial direction of the nut 294.

[0058] When the video monitoring system 5 observes that the first coal storage section 22 or the second coal storage section 23 is blocked, the air cannon 4 can be started, and the air cannon 4 can vibrate the side wall of the coal storage bin 2, so that the coal is vibrated and falls in time to avoid adhering to the inner wall. At the same time, the temperature sensor 31 monitors the temperature of the coal in the first coal storage section 22 and the second coal storage section 23 in real time. When the temperature of the coal is too high, the first coal storage section 22 and the second coal storage section 23 can be cooled to avoid the spontaneous combustion caused by the high temperature of the coal; the humidity sensor 32 monitors the humidity of the coal in the first coal storage section 22 and the second coal storage section 23 in real time.
