Description

Technical Field

[0001] The invention relates to the technical field of boiler equipment production and research and development, and in particular to a boiler with a flue gas treatment function. Background Art

[0002] In today's society, with the acceleration of industrialization and the increasing awareness of environmental protection, energy conservation, emission reduction and green production have become the core of sustainable development of enterprises. In this context, boilers with flue gas treatment functions, as outstanding representatives of environmental protection technology, are gradually becoming indispensable key equipment in the industrial field.

[0003] In the process of energy conversion, traditional boilers are often accompanied by the emission of a large amount of flue gas. These flue gases contain not only incompletely burned fuel particles, but also harmful substances such as sulfur dioxide, nitrogen oxides, particulate matter and carbon dioxide, which cause serious pollution to the atmospheric environment and threaten human health and ecological balance. Therefore, the development and application of boilers with efficient flue gas treatment functions has become an urgent need to solve this problem. Boilers with flue gas treatment functions integrate advanced flue gas purification systems on the basis of retaining the efficient heat energy conversion capabilities of traditional boilers. The system deeply treats the flue gas discharged by the boiler through a series of physical, chemical and biological processes. First, efficient dust removal devices such as bag filters or electrostatic precipitators are used to effectively capture and remove large particles of dust in the flue gas, significantly reducing the content of suspended matter in the air. Subsequently, through desulfurization and denitrification technologies such as wet desulfurization and selective catalytic reduction (SCR) denitrification, sulfur dioxide and nitrogen oxides in the flue gas are converted into harmless or low-toxic substances, greatly reducing the source of environmental problems such as acid rain and photochemical smog.

[0004] In addition, some advanced boilers are equipped with carbon dioxide capture and storage (CCS) technology, which aims to explore and practice new ways to reduce carbon emissions. These technologies separate and compress carbon dioxide from flue gas through specific chemical absorption or physical adsorption processes, and eventually store it underground or use it as a resource, contributing to addressing global climate change; There are still the following defects in specific use: 1. The waste of chemicals means that more chemicals need to be purchased to replenish them, which directly increases the cost of raw materials. At the same time, the treatment of discharged waste chemicals also requires additional equipment and operating costs, such as wastewater treatment, waste residue disposal, etc. Waste and discharge may also lead to other indirect costs, such as increased equipment maintenance costs (due to corrosion or blockage of equipment by chemicals), increased cleanup costs (handling leaks or overflows) and possible fines (due to violations of environmental regulations); discharged waste chemicals may enter water bodies, causing damage to aquatic ecosystems, affecting water quality safety, and even threatening human drinking water sources.

[0005] 2. In addition, vortex and backflow phenomena will cause uneven flue gas flow velocity, with the velocity in some areas being too high and the velocity in some areas being too low or even countercurrent. This uneven flow state will increase the turbulence intensity of the flue gas, thereby increasing energy loss; vortex and backflow phenomena will cause uneven flue gas flow velocity, with the velocity in some areas being too high and the velocity in some areas being too low or even countercurrent. This uneven flow state will increase the turbulence intensity of the flue gas, thereby increasing energy loss; the high-speed airflow in the vortex may cause erosion and wear on the flue wall or the surface of the heat exchange equipment, shortening the service life of the equipment.

[0026] The complete working principle and steps of the above embodiment are as follows: Initial qualification: Figure 1 to Figure 2 As shown, the operation of the boiler body 1 first starts from the combustion chamber 14. The combustion chamber 14 is the core part of the boiler and is responsible for the combustion of the fuel. Here, the fuel such as coal, natural gas or heavy oil is mixed with air and starts to burn after being ignited. In order to ensure the full combustion of the fuel, the air intake pipe 13 introduces external air into the combustion chamber 14, and the air and fuel are mixed in a certain proportion.

[0027] During the combustion process, the carbon, hydrogen and other components in the fuel react with oxygen to release a large amount of heat energy. At this time, the temperature in the combustion chamber 14 rises sharply, and the high-temperature gas produced by the combustion can usually reach 800°C to 1200°C. The key to this stage is to ensure the full combustion of the fuel, which directly affects the thermal efficiency of the boiler and the pollutants emitted; The high temperature gas generated by the combustion flows through the exhaust pipe 11 to the heat exchange tube 12. In the heat exchange tube 12, water or other working fluid flows on the other side of the boiler. The design of the heat exchange tube 12 is very important, and their material, thickness and shape will affect the efficiency of heat transfer.

[0028] The principle of heat exchange is that heat is transferred from the high temperature gas to the flowing water through the wall of the heat exchange tube 12. After absorbing the heat, the water temperature rises, and part of the water may be converted into steam. In modern boilers, the heat exchange tube 12 is usually made of a material with high thermal conductivity to improve the heat exchange efficiency and reduce heat loss; The intake pipe 13 is responsible for introducing fresh air into the combustion chamber 14. In order to achieve efficient combustion, the design of the intake pipe 13 is also important. The intake air volume needs to match the fuel supply volume to maintain the best combustion ratio; The exhaust gas generated in the combustion chamber 14 is discharged outside the boiler through the exhaust pipe 11. The exhaust pipe 11 not only needs to withstand high temperatures, but also needs to effectively discharge harmful gases; In summary, the working process of the boiler body 1 can be summarized into the following steps: 1. Fuel supply: solid, liquid or gaseous fuel is fed into the combustion chamber 14.

[0029] 2. Air introduction: Fresh air is introduced through the intake pipe 13 and mixed with the fuel.

[0030] 3. Combustion process: The fuel reacts with the air in the combustion chamber 14 to generate high-temperature combustion gases.

[0031] 4. Heat exchange: The high-temperature gas passes through the heat exchange tube 12, transferring heat to the flowing water or working fluid, and the water is heated or even converted into steam.

[0032] 5. Waste gas emission: The waste gas generated after combustion is discharged outside the boiler body 1 through the exhaust pipe 11.

[0033] When using: The reagent circulation mechanism 2 steps to make the chemical agent fully contact and react with the harmful substances in the flue gas: like Figure 3 to Figure 4 As shown, when the flue gas generated by burning raw materials in the combustion chamber 14 enters the interior of the reaction chamber 22, since the flue gas contains sulfur dioxide SO2, it needs to be removed by a desulfurization device such as wet desulfurization or dry desulfurization. Therefore, the operator can pour the limestone slurry used for wet desulfurization into the interior of the reaction chamber 22 through the feed port 25 connected to the surface of the cover plate 21, and then react with the flue gas to generate gypsum to achieve the desulfurization effect. In addition, the reduction motor connected to one end of the drive shaft 23 is started to drive the drive shaft 23 to rotate, so that the windmill 24 fixedly connected to the output end of one end of the drive shaft 23 will rotate with the drive shaft 23, so that the limestone slurry flowing in through the feed port 25 will be pushed into the upper surface of the inclined plate 26 by the rotation of the windmill 24, and the inclined plate 26 is inclined, so that the limestone slurry falling on the surface of the inclined plate 26 will flow into the interior of the liquid storage tank 27 through the inclined chute opened inside the inclined plate 26 for storage, thereby realizing the recycling of chemical agents and energy saving and emission reduction; A 3-step flow hub that distributes fumes and chemicals more evenly to the treatment area: like Figures 5 and 6As shown, when the windmill 24 rotates, the rotating shaft 31 fixedly connected at the axis center of the outer wall of one side of the windmill 24 will rotate synchronously, and then the upper rotating ring 32 fixedly connected to one end of the rotating shaft 31 near the windmill 24 will also rotate, so that the lower rotating ring 33 connected to one end of the upper rotating ring 32 will rotate together with the rotation of the upper rotating ring 32, so the rotation of the lower rotating ring 33 will drive the intermittent gear 34 fixedly connected to one side of the outer wall to rotate, so that the ring gear 35 meshing therewith will also rotate, and then the chuck 36 fixedly connected to the outer wall of one side of the ring gear 35 will rotate together with the rotation of the ring gear 35, so that the clamping block 37 clamped on the outer wall of the chuck 36 will rotate with the rotation of the chuck 36, and then the clamping block 37 The rotation will pull the rod connecting block 38 rotatably connected to the outer wall of one side of the clamping block 37 to slide on the inner wall of the U-shaped block 39, so that the movement of the rod connecting block 38 will pull the connecting shaft 310 of a section of the outer wall of the rod connecting block 38 to move, so that the crank 311 rotatably connected to one end of the connecting shaft 310 will be deflected, and then the deflection of the crank 311 will drive the short rod 312 rotatably connected to the crank 311 to be deflected, so that the deflection of the short rod 312 will pull the fixed shaft 313 fixedly connected to one end of the short rod 312 to move horizontally, so that the horizontal movement of the fixed shaft 313 will pull the fixed shaft 313 to swing in the vertical direction, and the reciprocating vertical swing of the wedge plate 314 will guide the flue gas to better contact with the chemical agent; The four steps of the gas collection cage mechanism to effectively control gas flow and improve the overall distribution of gas flow: like Figures 7 and 8 As shown, when the rotating shaft 31 rotates, the sleeve shaft 41 fixedly connected to the outer wall of the rotating shaft 31 will rotate together, and then the connecting ball shaft 46 penetrating and fixedly connected to the outer wall of the sleeve shaft 41 will also rotate, so that the cam 42 rotatably connected to the outer wall of the connecting ball shaft 46 will also rotate, and then the circumscribed shaft 43 eccentrically fixedly connected to the outer wall of one side of the cam 42 will also rotate, so that the long rod 44 rotatably connected to the outer walls of both sides of the circumscribed shaft 43 will also deflect, and then the cage 45 fixedly connected to the outer wall of one end of the long rod 44 will also deflect with the deflection of the long rod 44, thereby driving the deflection of the long rod 44 and the cage 45 through the rotation and deflection of the cam 42 to effectively capture and guide the smoke, ensuring that the smoke can be quickly collected after it is generated; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
