Description

Technical Field

[0001] The present application relates to the technical field of thermal power generation, and in particular to an ash dust-proof emission structure for a thermal power plant. Background Art

[0002] my country currently has a large number of thermal power plants and cogeneration plants equipped with slag removal systems for their boilers. Currently, the slag is typically discharged, cooled, and then temporarily stored in a slag bin before being loaded onto trucks for transportation and comprehensive utilization. When slag is discharged from existing slag bins, the slag, flowing down from a high position, generates a large amount of induced airflow in the open space, causing ash dust to overflow and create severe dust in the workspace. This necessitates the installation of dust control equipment to prevent dust. Existing dust control systems often use dustproof cloth to cover the discharge.

[0003] Chinese utility model patent: CN217946997U, publication (announcement) date: 2022.12.02, discloses a dust-proof emission structure for ash from a thermal power plant, including a dump truck and a bulk loader, and also includes a tarpaulin, the tarpaulin covering the top of the dump truck's bucket, and the tarpaulin can be detachably installed around the top of the dump truck's bucket; a mounting hole is provided in the middle of the tarpaulin, and the bulk head of the bulk loader is fixedly sleeved in the mounting hole; its advantage is that relatively clean and controllable civilized production is achieved during the entire loading and unloading process, ensuring the cleanliness and hygiene of the working space and factory area.

[0004] Although the above-mentioned ash dust-proof discharge structure of the thermal power plant forms a relatively sealed space through the tarpaulin and the truck bed, which solves the serious dust problem in the working space caused by the open loading and unloading of ash from the existing slag storage when it is discharged and transported out, it is not effective in preventing the ash from dusting during the operation of the thermal power plant, and the dust problem still exists. Summary of the Invention

[0005] In response to the above problems, the present application provides an ash dust prevention and emission structure for thermal power plants, which improves the dust prevention effect through continuous water supply from the water tank and the sealing design of the atomizing nozzle; it also slows down the falling speed of the ash through buffer soft bags and speed reducers, thereby reducing dust.

[0006] To achieve the purpose of this application, this application provides the following technical solutions:

[0007] An ash dust-proof discharge structure for a thermal power plant comprises: a slag discharge box, a water tank fixedly mounted on the top of the slag discharge box, a water inlet fixedly mounted on one side of the top of the water tank, and a connecting valve fixedly mounted on the other side of the top;

[0008] A water pump is fixedly installed on the left side of the water tank;

[0009] Three water outlet blocks are fixedly installed on the three sides of the water tank, a micro pump is fixedly installed on one side of the water outlet block, and an atomizing nozzle is fixedly installed on the bottom of the micro pump;

[0010] A sealing cover is movably connected to the top of the water inlet, a vent pipe is fixedly installed inside the sealing cover, a support rod is fixedly installed on the top of the vent pipe, a spring is fixedly installed on the bottom of the support rod, a sealing plate is fixedly installed on the bottom of the spring, and four side panels are fixedly installed on the top of the sealing plate.

[0011] In a possible implementation, a slag discharge funnel is fixedly installed at the bottom of the slag discharge box, and a slag discharge port is fixedly installed at the bottom of the slag discharge funnel.

[0012] In a possible implementation, a support groove is fixedly installed at the middle outer ring of the slag outlet, and a slag discharge pipe is fixedly connected to one side of the slag discharge box.

[0013] In a possible implementation, one side of the slag discharge pipe is fixedly connected to a slag discharge device.

[0014] In a possible implementation, the bottom of the support groove is movably connected to a connecting groove, four connecting bolts are movably connected around the bottom of the connecting groove, and four screw holes are provided at the bottom of the support groove to accommodate the four connecting bolts.

[0015] In a possible implementation, a soft buffer bag is fixedly mounted on the bottom of the connecting groove, and a connecting pipe is fixedly mounted on the bottom of the soft buffer bag.

[0016] In a possible implementation, a speed reducer is fixedly installed inside the connecting pipe, and a discharge funnel is fixedly installed at the bottom of the connecting pipe.

[0017] In a possible implementation, the cushioning soft bag is made of a flexible and stretchable silicone material.

[0018] In a possible implementation, the support rod is arranged in a cross shape.

[0019] In a possible implementation, the atomizing nozzle is sealed on a side close to the water tank.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The ash dust-proof discharge structure for thermal power plants can be connected to an external water pipe through a connecting valve to continuously supply water to the water tank. Through the operation of the micro pump, the water inside the water tank can be pumped into the water outlet block and then sent to the atomizing nozzle for spraying. The nozzle of the atomizing nozzle close to the side of the water tank is sealed to prevent the water sprayed by the atomizing nozzle from accumulating on one side of the water tank. When the micro pump is running, negative pressure is generated inside the water tank, driving the spring to expand and contract, thereby driving the sealing plate to move downward, allowing outside air to enter from the gap on one side of the side plate, thereby improving the practicality and dust-proof effect of the ash dust-proof discharge structure for thermal power plants.

[0022] 2. The ash dust-proof emission structure for thermal power plants can connect the connecting groove and the supporting groove through four connecting bolts around the bottom of the connecting groove. The buffer soft bag can slow down the falling speed of the ash. The speed reduction plate inside the connecting pipe can guide the falling material to both sides, thereby slowing down the falling speed. The ash can be guided and discharged through the discharge funnel, thereby improving the dust-proof effect of the ash dust-proof emission structure for thermal power plants and avoiding the problem of large-scale dust caused by excessively fast falling speed.

[0035] Specifically, the ash can be sent into the slag box 1 through the slag discharge pipe 14 , the slag can be discharged through the slag discharge funnel 11 , and the ash can be sent into the buffer soft bag 22 through the slag discharge port 12 .

[0036] In one possible embodiment, the bottom of the support groove 13 is movably connected to the connecting groove 2, and four connecting bolts 21 are movably connected around the bottom of the connecting groove 2. The bottom of the support groove 13 is provided with four screw holes for the four connecting bolts 21.

[0037] A buffer bag 22 is fixedly installed at the bottom of the connecting groove 2, and a connecting pipe 23 is fixedly installed at the bottom of the buffer bag 22;

[0038] A deceleration plate 24 is fixedly installed inside the connecting pipe 23, and a discharge funnel 25 is fixedly installed at the bottom;

[0039] Specifically, the connecting groove 2 and the supporting groove 13 can be connected by connecting bolts 21 and screw holes, the ash can be buffered by the buffer bag 22, the ash can be decelerated by the deceleration plate 24 inside the connecting pipe 23, and the ash can be discharged through the discharge funnel 25;

[0040] Specifically, the cushioning soft bag 22 is made of flexible and stretchable silicone material.

[0041] In a possible embodiment, a water tank 3 is fixedly installed on the top of the slag box 1, a water inlet 31 is fixedly installed on one side of the top of the water tank 3, and a connecting valve 32 is fixedly installed on the other side of the top;

[0042] A water pump 36 is fixedly installed on the left side of the water tank 3;

[0043] Three water outlet blocks 33 are fixedly installed on the three sides of the water tank 3, a micro pump 34 is fixedly installed on one side of the water outlet block 33, and an atomizing nozzle 35 is fixedly installed on the bottom of the micro pump 34;

[0044] Specifically, the micro pump 34 can be used to pump water from the water tank 3 through the water outlet block 33 and then spray it out from the atomizing nozzle 35.

[0045] Specifically, the connecting valve 32 can pump water from the water tank 3 through the water pump 36 .

[0046] In a possible implementation, the atomizing nozzle 35 is sealed on one side close to the water tank 3 , thereby preventing the atomized water from being sprayed onto one side of the water tank 3 .

[0047] In a possible implementation, the water pump 36 is externally connected to a pipeline, which can be connected to an industrial water source to replenish the water tank 3 .

[0048] In a possible embodiment, a sealing cover 4 is movably connected to the top of the water inlet 31;

[0049] A vent pipe 41 is fixedly installed inside the sealing cover 4, and a support rod 42 is fixedly installed on the top of the vent pipe 41. The support rod 42 is arranged in a "cross" shape;

[0050] A spring 43 is fixedly mounted on the bottom of the support rod 42, a sealing plate 44 is fixedly mounted on the bottom of the spring 43, and four side plates 45 are fixedly mounted on the top of the sealing plate 44;

[0051] Specifically, when the micro pump 34 is running, negative pressure is generated in the water tank 3, driving the spring 43 to expand and contract, thereby driving the sealing plate 44 to move up and down, allowing outside air to enter from the gap on one side of the side plate 45 to achieve the purpose of balancing the pressure.

[0052] The working principle of this utility model is as follows:

[0053] First, the ash is sent from the inside of the slag discharge pipe 14 into the inside of the slag discharge box 1 through the operation of the slag discharge device 15, and finally sent to the slag discharge port 12 from the slag discharge funnel 11 at the bottom of the slag discharge box 1. The ash flows along the slag discharge port 12 into the inside of the buffer bag 22. The buffer bag 22 is made of a flexible and elastic silicone material. When the ash falls, the buffer bag 22 can slow down the falling speed of the ash. The speed reducer 24 inside the connecting pipe 23 can guide the falling ash to move to both sides, so that it can be guided and discharged through the discharge funnel 25. This improves the practicality of the ash dust prevention and emission structure used in thermal power plants and avoids the problem of large-scale dust caused by the ash falling too fast.

[0054] When the cushioning bag 22 needs to be cleaned or replaced, the connecting groove 2 can be separated from the supporting groove 13 by rotating the four connecting bolts 21, so that the cushioning bag 22 can be removed for cleaning or replacement, further improving the practicality of the structure.

[0055] Furthermore, the sealing cover 4 can be opened by rotating it, allowing water to be added to the water tank 3, and then closed again. Three micropumps 34 operate to pump water from the water tank 3 through the outlet block 33 and into the atomizing nozzle 35. The atomizing nozzle 35 atomizes the water and sprays it out, thereby shielding dust and enhancing the dust-proofing effectiveness of the ash dust discharge structure. The nozzle of the atomizing nozzle 35, located near one side of the water tank 3, is sealed, preventing water from spraying onto that side, further enhancing its practicality.

[0056] When micropump 34 operates, negative pressure is generated inside water tank 3, causing spring 43 at the bottom of support rod 42 to expand and contract, causing sealing plate 44 to move downward. External air enters water tank 3 through the gap in side panel 45. Water can be drawn into water tank 3 through connecting valve 32 by pumping pump 36, thereby continuously supplying water to water tank 3.

[0057] The above embodiments are intended only to illustrate the technical solutions of the present application and are not intended to limit them. The present application is not limited to the precise structures described above and illustrated in the accompanying drawings, and it cannot be assumed that the specific implementation of the present application is limited to these descriptions. For those skilled in the art of the present application, any changes and modifications made without departing from the concept of the present application should be deemed to fall within the scope of protection of the present application.
