Description

Technical Field

[0001] The invention belongs to the technical field of carbon emission metering equipment, in particular to a carbon emission metering equipment for a thermal power plant. Background Art

[0002] The carbon emission metering equipment of thermal power plants is a device used to accurately measure the amount of greenhouse gases such as carbon dioxide emitted into the atmosphere during the production process of thermal power plants. In practical applications, in order to ensure the accuracy of measurement and the normal operation of the equipment, the gas usually needs to be pre-treated, which includes filtering and other steps. The filtering is to prevent impurities such as dust and particulate matter carried in the gas from entering the metering equipment, which may be deposited on the sensor surface, block the gas channel or affect the optical path of the optical element, thereby reducing the measurement accuracy of the equipment or even damaging the equipment.

[0003] A Chinese patent with announcement number CN117959843B discloses a carbon emission metering device for a chemical park, including a filter housing, an outer surface of the filter housing is fixedly connected to a cover plate, an outer surface of the cover plate is fixedly connected to an air intake pipe, a first sealing door is provided on both sides of the filter housing below the cover plate, an outer surface of the filter housing away from the cover plate is fixedly connected to a first connecting pipe, one end of the first connecting pipe is fixedly connected to a metering module, a surface of the metering module away from the first connecting pipe is fixedly connected to a second connecting pipe, and one end of the second connecting pipe is fixedly connected to a purification housing.

[0004] The prior art has the following problems: first, the structural design is not reasonable enough. The filter is driven by gas to rotate, and its rotation speed is affected by the amount of gas and is not controlled manually. The filter rotates too slowly or too quickly, which respectively leads to untimely scraping of impurities and difficult scraping of sticky impurities; incomplete scraping, and impurities in some areas are not scraped off; and when impurities accumulate on the fan blades or shafts, the rotation of the filter is blocked, affecting its impurity cleaning effect;

[0005] The second is that after the scraper finishes scraping off the impurities on the surface of the filter, the scraped impurities are not removed in time, which results in that when the scraper scrapes off the impurities on the filter again, due to the sticky impurities' ability to carry away, some of the sticky impurities on the scraper edge that have been scraped off are entrained and contact the filter again, resulting in poor scraping effect of the impurities on the filter; for this reason, the present invention provides a carbon emission metering device for a thermal power plant.

[0006] In order to make up for the shortcomings of the prior art and solve the problem of unreasonable structural design, the filter is driven to rotate by gas, and its rotation speed is affected by the amount of gas and is not manually controlled.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figures 1 to 9As shown, a carbon emission metering device for a thermal power plant described in an embodiment of the present invention comprises an air intake pipe 1; a meter 11 is provided on the air intake pipe 1; a steam device 12 and a pressure pump 13 are provided at the proximal end of the air intake pipe 1, and the steam in the steam device 12 is pressurized by the pressure pump 13; a fixing ring 14 is fixedly connected to the outer circular wall of the air intake pipe 1; a rotating shaft 15 is rotatably connected in the fixing ring 14, and the top end of the rotating shaft 15 passes through the air intake pipe 1, and the rotating shaft 15 is driven to rotate by the steam device 12; a protective shell 16 is fixedly connected to the inner wall of the air intake pipe 1 through a fixing rod, and the rotating shaft 15 passes through the protective shell 16; the air intake pipe 1 A filter plate 17 is rotatably connected inside, and a rotating rod 18 is fixed at the center of the filter plate 17. A bevel gear 19 is fixed to the rotating rod 18 and the rotating shaft 15, and a pair of bevel gears 19 are meshed with each other, and the pair of bevel gears 19 are both located in the protective shell 16; a scraper block 191 is provided on the side wall of the filter plate 17, and the scraper block 191 is vertically arranged and corresponds to the position of the rotating rod 18; the contact angle between the scraper block 191 and the filter plate 17 is an acute angle; a fixed shell 192 is fixed to the outer circular wall of the intake pipe 1; a partition 193 is fixed between the inner walls of the fixed shell 192, and a push rod 194 is slidably connected to the top of the partition 193 through a square groove. The scraper block 191 is pushed close to the filter plate 17 and contacts the filter plate 17 through the push rod 194; the fixed shell 192 is provided with a scraper assembly, and the impurities on the filter plate 17 are cleaned by the scraper assembly; when working, the steam device 12 (the hydrogen element in the fuel will combine with oxygen to generate water vapor during the combustion process. At the same time, in some flue gas treatment processes, such as wet desulfurization process, the water vapor content in the flue gas will also increase. The above water vapor is injected into the steam engine and reused. It can be used as a power source without affecting the recovery and reuse of water vapor. This is a prior art and will not be described in detail here) drives the rotating shaft 15 to rotate, so that the filter plate The rotation speed of 17 is relatively linear, so that the efficiency of scraping impurities on the surface of the filter plate 17 by the scraper 191 is high, and it is avoided that due to unreasonable structural design, the fan blades are driven by gas to rotate, and dust particles are attached to the fan blades, increasing the weight and surface roughness of the fan blades, thereby affecting the rotation of the filter plate 17, and sticky substances may directly stick to the rotation connection points of the fan blades, thereby affecting the rotation of the fan blades, and further affecting the removal of impurities on the filter plate 17, and because the acidic gas contained in the gas reacts with the fan blades, affecting their rotation (by adjusting the speed of the steam-driven rotating shaft 15, it is avoided that impurities on some filter plates 17 are not scraped off by the scraper 191).

[0037] The scraping assembly includes a fixed block 2, a power unit and a collecting unit; the top of the partition 193 is fixedly connected to the fixed block 2, and the side wall of the fixed block 2 is slidably connected to a sliding column 21 through a circular groove, the end of the sliding column 21 is fixedly connected to the side wall of the scraping block 191, and the end of the sliding column 21 is fixedly connected to an arc-shaped rubber block 22, and the arc-shaped rubber block 22 and the push rod 194 are in corresponding positions, and the arc-shaped rubber block 22 and the fixed block 2 are fixedly connected through a spring; the top of the partition 193 is provided with a square The partition plate 193 is provided with a T block 25 which is slidably connected to the partition plate 193 through a T slot 24. The side wall of the T block 25 is fixedly connected to the side wall of the T slot 24 through a spring. The side wall of the T block 25 is slidably connected to an L block 26 through a through slot, and the L block 26 is fixedly connected to the side wall of the T block 25. A cleaning block 27 is fixedly connected to the top of the L block 26. The cross-sections of the cleaning block 27 and the scraping block 191 are both triangular, and the positions of the scraping block 191 and the cleaning block 27 correspond to each other. The intake pipe 1 is fixedly connected to a V through a fixed slot. The guide rod 34 and the scraper block 191 are both located in the V-shaped guide plate 28; when working, the power unit drives the push rod 194 to continuously approach, touch and move away from the sliding column 21, and this method is repeated, so that the scraper block 191 continuously approaches, touches and moves away from the filter plate 17. When the scraper block 191 contacts the filter plate 17, the scraper block 191 scrapes off the impurities on the surface of the filter plate 17 to avoid the accumulation of sticky impurities on the surface of the filter plate 17 and affect its filtering effect; at this time, the scraped impurities Impurities accumulate on one side of the scraper block 191. When the scraper block 191 is away from the filter plate 17, the scraper block 191 contacts the cleaning block 27. The cleaning block 27 scrapes off the impurities accumulated on the surface of the scraper block 191 again, causing the impurities to fall into the square groove 23. This prevents the scraper block 191 from scraping off the impurities on the filter plate 17 next time. The surface of the scraper block 191 is not cleaned in time due to the accumulation of impurities last time, so that when it contacts the filter plate 17 again, the last impurities will adhere to the filter plate 17 again, resulting in a poor effect of scraping off impurities.

[0038] The power unit includes a pulley 3; a first shaft is rotatably connected to the bottom of the fixed shell 192, and the first shaft and the rotating shaft 15 are both fixedly connected with pulleys 3, and a pair of the pulleys 3 are driven by a synchronous belt 31, and the synchronous belt 31 runs through the fixed shell 192; a rotating column 32 is rotatably connected to the top of the pulley 3 on the first shaft, and a sliding cover 33 is sleeved on the top of the rotating column 32, and the rotating column 32 is slidably connected in the sliding cover 33, and the side walls at both ends of the sliding cover 33 are slidably connected to guide rods 34 through round grooves, and both ends of the guide rods 34 are aligned with the inner wall of the fixed shell 192. The top of the sliding cover 33 and the bottom of the push rod 194 are fixedly connected; when working, the pulley 3 is driven to rotate by the rotating shaft 15 and the synchronous belt 31, and the steam equipment 12 is used as a power linkage to fully reuse the water vapor generated in the production process of the thermal power plant, thereby avoiding the waste of energy. The pulley 3 on the first axis rotates, because the sliding cover 33 is limited in direction by the guide rod 34, the rotating column 32 continuously drives the sliding cover 33 to move, thereby driving the push rod 194 to continuously approach, contact and move away from the scraper block 191, which is a reciprocating cycle, so that the effect of scraping impurities is better.

[0039] The collecting unit includes a collecting box 4; the scraping block 191 and the cleaning block 27 are both located directly above the square groove 23; the side wall of the fixed shell 192 is slidably connected to the collecting box 4 through the collecting groove, and the position of the collecting box 4 corresponds to the position of the square groove 23; the side wall of the collecting box 4 is fixedly connected to the inner wall of the fixed shell 192 through a spring; the side wall of the collecting box 4 is fixedly connected to a connecting rod 41, and the connecting rod 41 passes through the fixed shell 192; when working, the sticky impurities accumulated on one side of the scraping block 191 are scraped off by the cleaning block 27 to prevent the impurities from being in contact with the scraping block 191 and the filter plate 17 in the next cycle. Part of the impurities are carried into the space between the scraping block 191 and the filter plate 17 due to the contact between the scraping block 191 and the filter plate 17, thereby affecting the impurity scraping effect.

[0040] Embodiment 2

[0041] like Figures 3 to 9As shown, on the basis of the first embodiment, springs of the block 5 and its side walls are added, so that the contact time between the scraper block 191 and the filter plate 17 is increased, and the efficiency of scraping impurities is further increased; a pair of blocks 5 are fixedly connected to the push rod 194, and a pair of the side walls of the block 5 are fixedly connected with springs, and the positions of the springs and the arc rubber block 22 correspond to each other; when working, the springs on the side walls of the block 5 can be set up, so that when the push rod 194 pushes the sliding column 21 to drive the scraper block 191 to scrape impurities on the surface of the filter plate 17, the springs on the side walls of the block 5 pre-extrude the sliding column 21, so that the scraper block 191 first contacts the scraper block 191, thereby increasing the contact and scraping time between the scraper block 191 and the filter plate 17, and because of the elastic contact, the scraper block 191 and the surface of the filter plate 17 are more tightly contacted, and the simple parts have obvious significance, low cost and stable operation.

[0042] A group of arc blocks 6 are fixedly connected to the side wall of the cleaning block 27, and the arc blocks 6 and the side positions of the scraper block 191 correspond to each other; the side wall of the cleaning block 27 is provided with an inclined groove 61, and the cross-section of the inclined groove 61 from the top to the bottom of the cleaning block 27 gradually increases; during operation, through the establishment of the arc blocks 6, the scraper block 191 can continuously squeeze the arc blocks 6 on the side wall of the cleaning block 27 in the process of approaching and contacting the filter plate 17, so that the cleaning block 27 drives the T block 25 to vibrate continuously through the L block 26, thereby causing the removed impurities remaining on the surface of the cleaning block 27 to fall off and avoid their accumulation on the cleaning block 27. The establishment of the inclined groove 61 can prevent the impurities on the top of the cleaning block 27 from falling off, and can prevent the impurities on the top of the cleaning block 27 from falling down and falling on the impurities at the lower end of the cleaning block 27, and the impurities at the lower end just do not fall here, so that the impurities at the upper end accumulate and adhere to the impurities at the lower end, thereby forming stubborn impurities that are difficult to remove.

[0043] Embodiment 3

[0044] like Figures 4 to 9 As shown, a pair of heating wires are provided on the inner wall of the collecting box 4, and the internal groove of the collecting box 4 is inclined toward the collecting groove; the side walls of the scraper block 191 and the cleaning block 27 are fixed with heating wires through the placement grooves; when working, the accumulation of impurities can be avoided by setting up the heating wires, and the appropriate temperature can prevent sticky impurities from adhering and being difficult to remove.

[0045] The scraper block 191, V-shaped guide plate 28 and cleaning block 27 are made of polytetrafluoroethylene. When working, polytetrafluoroethylene material not only has low viscosity but also has good chemical stability, which is suitable for use in this environment, avoiding impurities adhering to the surface of the V-shaped guide plate 28 and the scraper block 191, making them difficult to remove.

[0046] Working principle: The steam device 12 (the hydrogen element in the fuel will combine with oxygen to generate water vapor during the combustion process. At the same time, in some flue gas treatment processes, such as the wet desulfurization process, the water vapor content in the flue gas will also increase. The above water vapor is injected into the steam engine and reused. It can be used as a power source without affecting the recovery and reuse of water vapor. This is a prior art and will not be described in detail here) drives the rotating shaft 15 to rotate, so that the rotation speed of the filter plate 17 can be more linear, so that the efficiency of scraping impurities on the surface of the filter plate 17 by the scraper block 191 is higher, and it is avoided that the fan blades are driven by gas to rotate due to unreasonable structural design, and dust particles are attached to the fan blades, which increases the weight and surface roughness of the fan blades, thereby affecting the filter plate 1 7, and the sticky substance may directly stick to the rotation connection point of the fan blade, thereby affecting the rotation of the fan blade, and further affecting the removal of impurities on the filter plate 17, and because the acid gas contained in the gas reacts with the fan blade, affecting its rotation (by adjusting the speed of the steam-driven rotating shaft 15, it is prevented that some impurities on the filter plate 17 are not scraped off by the scraper block 191), and the power unit drives the push rod 194 to continuously approach, touch and move away from the sliding column 21. This method is cyclically carried out, so that the scraper block 191 continuously approaches, touches and moves away from the filter plate 17. When the scraper block 191 contacts the filter plate 17, the impurities on the surface of the filter plate 17 are scraped off by the scraper block 191, avoiding the accumulation of sticky impurities on the surface of the filter plate 17 and affecting its filtering effect;At this time, the scraped impurities are accumulated on one side of the scraper block 191. When the scraper block 191 is away from the filter plate 17, the scraper block 191 contacts the cleaning block 27, and the cleaning block 27 scrapes the impurities accumulated on the surface of the scraper block 191 again, so that the impurities fall into the square groove 23, so as to avoid that the scraper block 191 surface is not cleaned in time due to the accumulation of impurities last time when the scraper block 191 scrapes the impurities from the filter plate 17 next time, so that when it contacts the filter plate 17 again, the impurities from last time are adhered to the filter plate 17 again, so that the effect of scraping impurities is poor, and the pulley 3 is driven to rotate by the rotating shaft 15 and the synchronous belt 31, which is the steam equipment 12 as a power linkage, which fully recycles the water vapor generated in the production process of the thermal power plant The use of the pulley 3 on the first axis avoids the waste of energy. Because the sliding cover 33 is limited in direction by the guide rod 34, the rotating column 32 continuously drives the sliding cover 33 to move, thereby driving the pushing rod 194 to continuously approach, contact and move away from the scraper block 191. This is a reciprocating cycle, which makes the effect of scraping impurities better. The sticky impurities accumulated on one side of the scraper block 191 are scraped off by the cleaning block 27 to avoid the impurities from being carried into the space between the scraper block 191 and the filter plate 17 in the next cycle due to the contact between the scraper block 191 and the filter plate 17, thereby affecting the impurity scraping effect. The side wall spring of the block 5 is set up to make the pushing rod 194 continuously approach, contact and move away from the scraper block 191. When the rod 194 pushes the sliding column 21 to drive the scraper block 191 to scrape the impurities on the surface of the filter plate 17, the spring on the side wall of the block 5 pre-compresses the sliding column 21, so that the scraper block 191 first contacts the scraper block 191, thereby increasing the contact and scraping time between the scraper block 191 and the filter plate 17, and because of the elastic contact, the scraper block 191 and the surface of the filter plate 17 are more tightly contacted. Through the establishment of the arc block 6, the scraper block 191 can continuously squeeze the arc block 6 on the side wall of the cleaning block 27 in the process of approaching and contacting the filter plate 17, so that the cleaning block 27 drives the T block 25 to vibrate continuously through the L block 26, thereby causing the cleaned impurities remaining on the surface of the cleaning block 27 to fall off and avoid their accumulation. On the cleaning block 27, the establishment of the inclined groove 61 can prevent the impurities on the top of the cleaning block 27 from falling without being blocked, and can prevent the impurities on the top of the cleaning block 27 from falling down and falling on the impurities at the lower end of the cleaning block 27, and the impurities at the lower end just do not fall here, so that the impurities at the upper end accumulate and adhere to the impurities at the lower end, thereby forming stubborn impurities that are difficult to remove. The establishment of the heating wire can prevent the accumulation of impurities, and the appropriate temperature can prevent the adhesion of sticky impurities and make them difficult to remove. The polytetrafluoroethylene material not only has low viscosity, but also has good chemical stability, which is suitable for use in this environment, and prevents the impurities from adhering to the surface of the V-shaped guide plate 28 and the scraper 191, making them difficult to remove. ;
