DETAILED DESCRIPTION

[0014] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0015] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should be the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0016] A thermal power plant is abbreviated as a thermal power plant. It is a factory that uses combustibles (such as coal) as fuel to produce electricity. Its basic production process is: when the fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. Most thermal power plants use coal to burn to generate heat, and coal will produce a lot of smoke during transportation and combustion, causing air pollution and endangering the health of workers. Therefore, dust suppression devices are generally installed in thermal power plants.

[0017] The existing dust reduction device converts water into spray and sprinkles it from the roof, which absorbs the dust in the air and drops it to the ground. However, when not in use, the sprayer is exposed to the air for a long time, and some dust in the air will be absorbed by the sprayer, which can easily cause the sprayer to be blocked, affecting the effect of the dust reduction device and reducing the service life of the sprayer.

[0018] The related technology discloses a dust reduction device inside a thermal power plant, comprising two mutually symmetrical mounting plates fixedly connected to the roof inside the thermal power plant, a bearing shell being mounted on the mounting plate, a mounting shell being fixedly arranged between the two bearing shells, the mounting shell being semicircular and a connecting plate being fixedly arranged at one end of the mounting shell. When in use, the driving device is started to drive the arc baffle to rotate with the center of the pipe as the axis, the arc baffle is rotated to between the pipe and the mounting shell, the faucet is turned on to transport water into the pipe through the water inlet pipe, and then the water is atomized and sprayed out through the spray nozzle. After use, the arc baffle is driven to rotate again to block the spray nozzle, so that the spray nozzle will not be exposed to the air for a long time when not in use and cause blockage, thereby ensuring the dust reduction effect of the device and extending the service life of the device.

[0019] However, after the dust removal, the dust removal device of the related art needs to use an additional power mechanism to drive the protection device to protect the sprinkler head, which increases the use and manufacturing costs. In addition, when the protection device switches to the state of protecting the sprinkler head, the speed is slow, which affects the protection effect.

[0020] Based on the above-mentioned related technology, the dust removal device needs to use an additional power mechanism to drive the protection device to protect the sprinkler head after dust removal, which increases the use and manufacturing costs, and the protection device has a slow speed when switching to the state of protecting the sprinkler head. The present invention proposes a dust removal device for an internal power plant.

[0021] The internal dust removal device of a power plant provided by the present invention uses a piston structure and a sliding plate. When water enters the dust removal device, the piston pushes the sliding plate so that the opening of the sliding plate is aligned with the shower head, so that the shower head can spray water to remove dust; the cylinder body is quickly depressurized by the pressure relief pipe and the electromagnetic pressure relief valve, and the spring is reset so that the piston drives the sliding plate, so that the shower head and the opening of the sliding plate are staggered, thereby protecting the shower head. No additional power mechanism is used in the whole process, reducing the use and manufacturing costs. In addition, when the protection device switches to the state of protecting the shower head, the speed is fast, which improves the protection effect.

[0022] Figure 1 The structure of the dust removal device according to the embodiment of the present invention is shown. Figure 2 A partial enlarged structure of a dust removal device according to an embodiment of the present invention is shown.

[0023] like Figure 1and Figure 2 As shown, an embodiment of the present invention provides a dust removal device, comprising:

[0024] Sprinkler head 1, spray water pipe 2, sliding plate 3, piston 4, cylinder body 5, spring 6, water inlet pipe 7, pressure relief pipe, electromagnetic pressure relief valve 11 and water supply pipe 8;

[0025] The sprinkler head 1 is connected to the sprinkler water pipe 2; the piston 4 is embedded in the cylinder body 5; one end of the sliding plate 3 is located in the cylinder body 5 and connected to the piston 4; the spring 6 is sleeved on the periphery of the sliding plate 3, and the two ends abut against the cylinder body 5 and the piston 4 respectively; the water inlet pipe 7 is connected to the cylinder body 5; the pressure relief pipe is connected to the water inlet pipe; the electromagnetic pressure relief valve 11 is connected to the pressure relief pipe; the water supply pipe 8 is connected to the cylinder body 5 and the sprinkler water pipe 2;

[0026] The sliding plate 3 is provided with an opening 9 adapted to the sprinkler head 1; when the water pressure in the cylinder body 5 is greater than the pressure applied by the spring 6 on the piston 4, the piston 4 is pushed close to the spring 6 and drives the sliding plate 3 to move so that the opening 9 corresponds to the position of the sprinkler head 1; when the pressure is relieved through the pressure relief pipe and the electromagnetic pressure relief valve 11, the water pressure in the cylinder body 5 is less than the pressure applied by the spring 6 on the piston 4, the piston 4 is pushed away from the spring 6, and drives the sliding plate 3 to move so that the opening 9 does not correspond to the position of the sprinkler head 1.

[0027] In this embodiment, one end of the water inlet pipe 7 away from the cylinder body 5 is connected to the high-pressure water circuit.

[0028] In this way, after the water inlet pipe 7 is opened to let in water, water enters the cylinder body 5, and the water pressure at the right end of the cylinder body 5 in the figure gradually exceeds the elastic force of the spring 6, causing the spring 6 to be compressed, and the piston 4 to move and drive the sliding plate 3. When the pressure at both ends of the piston 4 is balanced, the opening 9 of the sliding plate 3 is aligned with the sprinkler head 1, so that water can pass through the water supply pipe 8 and the sprinkler water pipe 2 in turn, and spray from the sprinkler head 1 into the air; when the pressure is relieved through the pressure relief pipe and the electromagnetic pressure relief valve 11, the spring 6 is quickly reset, pushing the piston 4 and driving the sliding plate 3, so that the opening 9 of the sliding plate 3 is staggered with the sprinkler head 1, thereby protecting the sprinkler head 1.

[0029] Considering that when only the sliding plate 3 is used for blocking, dust will still float into the area where the shower head 1 is located from the opening 9 and block the shower head 1 .

[0030] Figure 3 A partial enlarged structure of a dust removal device according to an embodiment of the present invention is shown.

[0031] refer to Figure 3 As an optional embodiment, the dust removal device also includes a protective tube 12.

[0032] The protection tube 12 is sleeved on the periphery of the shower head 1 .

[0033] In this embodiment, when the opening 9 of the sliding plate 3 is offset from the shower head 1 , the sliding plate 3 and the protection tube 12 enclose a closed area.

[0034] In this way, the protection of the shower head 1 is enhanced through the combination of the sliding plate 3 and the shower head 1 .

[0035] It is considered that a guide assembly is needed to guide the sliding plate 3 to prevent the sliding plate 3 from being misaligned during the sliding process.

[0036] As an optional embodiment, the dust removal device further includes a guide block 13 .

[0037] The guide block 13 is provided with a guide groove, which is matched with the sliding plate 3. The sliding plate 3 is connected with the guide groove in a matching manner.

[0038] In this way, the sliding plate 3 is guided by the guide block 13 to prevent the sliding plate 3 from being misaligned during the sliding process.

[0039] Considering that during the resetting process of the piston 4, if the piston 4 moves too long, the spring 6 will be located in the water inlet range of the water inlet pipe 7, causing water to enter the part of the cylinder body 5 where the spring 6 is located, affecting the normal use of the device.

[0040] As an optional embodiment, the dust removal device also includes a limiting ring 14.

[0041] The limiting ring 14 is fixed in the cylinder body 5 .

[0042] In this embodiment, the limiting ring 14 is located between the piston 4 and the water inlet pipe 7 .

[0043] In this way, by setting the limiting ring 14 to limit the stroke of the piston 4, the moving distance of the piston 4 will not be too long, thereby preventing the part of the cylinder body 5 where the spring 6 is located from entering water.

[0044] Considering that a switch assembly is needed to open and close the water inlet of the water inlet pipe 7.

[0045] As an optional embodiment, the dust removal device further includes a locking valve 15 .

[0046] The locking valve 15 is sleeved on the periphery of the water inlet pipe 7 .

[0047] In this way, the water inlet pipe 7 can be loosened or clamped by the locking valve 15, so that the water inlet pipe 7 can be opened and closed for water inlet.

[0048] Considering that a sensor component is needed to monitor the dust concentration in the air in real time, the dust removal device is turned on when the dust concentration in the air exceeds a preset threshold.

[0049] As an optional embodiment, the dust removal device also includes a dust sensor 16 .

[0050] The vertical position of the dust sensor 16 is lower than the vertical position of the shower head 1 .

[0051] In this embodiment, the dust sensor 16 is lower than the shower head 1, and can sense the change of dust concentration before and after the shower head 1 sprays. When the dust sensor 16 senses that the dust concentration exceeds a preset threshold, the locking valve 15 opens, water passes through the water inlet pipe 7, and the shower head 1 sprays water to remove dust; when the dust sensor 16 senses that the dust concentration reaches a preset dust removal target, the locking valve 15 closes, the electromagnetic pressure relief valve 11 opens, and the sliding plate 3 moves to protect the shower head 1.

[0052] In this way, the dust concentration in the air is monitored in real time by the dust sensor 16, and the dust removal is turned on when the dust concentration exceeds a preset threshold, and the dust removal is turned off when the dust concentration reaches a preset dust removal target.

[0053] It is considered necessary to prevent water from splashing onto the dust sensor 16 to avoid affecting the normal operation of the dust sensor 16 .

[0054] As an optional embodiment, the dust removal device further includes a water cover 17 .

[0055] The water cover 17 is provided between the slide plate 3 and the dust sensor 16 .

[0056] In this way, the water cover 17 prevents water from splashing onto the dust sensor 16 , thereby preventing the water from affecting the normal operation of the dust sensor 16 .

[0057] Considering that when the piston 4 moves, the gas volume on the spring 6 side in the cylinder 5 will change, the changed gas volume will affect the total pressure on the spring 6 side.

[0058] As an optional embodiment, the dust removal device further includes an air permeable tube 18 .

[0059] The air-permeable pipe 18 is fixed to the side of the cylinder body 5 close to the sliding plate 3 , and communicates the inside and outside of the cylinder body 5 .

[0060] In this way, the air pressure on one side of the spring 6 in the cylinder body 5 is communicated with the outside through the air vent, so as to prevent the air pressure from affecting the normal working of the piston 4.

[0061] As an optional embodiment, the dust removal device further includes a mounting frame 19 .

[0062] The spray water pipe 2 and the cylinder body 5 are both fixed to the mounting frame 19 .

[0063] In this embodiment, the mounting frame 19 serves as a support of the dust removal device, and the guide block 13 , the dust sensor 16 and the water cover 17 may also be fixed to the mounting frame 19 .
