Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue gas treatment equipment, in particular to an internal circulation magnetic field dry adsorption tower. BACKGROUND

[0002] The flue gas emission problem of coal-fired industry and hazardous waste disposal industry is increasingly prominent, and air pollution control has become the focus and difficulty in the field of environmental protection.

[0003] The current desulfurization and denitrification catalytic split-flow neutralization method adopts a wet process, which requires separate treatment of harmful gases containing sulfides, nitrates, nitrogen oxides, etc. This process is complex, involving multiple stages of catalytic reaction, powder spraying neutralization, water circulation cooling, etc. The equipment system is large, and the pipeline connection is complicated. In actual operation, the coordinated control between each subsystem is difficult, the technical requirements for operators are high, and the daily maintenance workload is huge. In particular, the catalyst bed is prone to blockage, and the spraying system is prone to scaling, which leads to frequent equipment failures, long maintenance cycles, and seriously affects the continuity of production.

[0004] The more prominent problem is that the operating cost of this process is high. This technology requires continuous addition of catalysts, calcium oxide powder, and ammonia water and other chemicals. The consumption of these consumables increases sharply with the increase in the amount of flue gas to be treated. Taking a 75-ton-per-hour industrial boiler as an example, the total cost of catalysts, chemical reagent procurement, and circulating water system operation is about 5 million yuan per year, and this cost will further increase as environmental protection standards improve. This high operating cost has placed a heavy economic burden on enterprises, especially small and medium-sized enterprises.

[0005] In addition, the wet desulfurization and denitrification process also has the problem of secondary pollution. The waste water produced by the circulating water system contains high concentrations of sulfates, nitrates and other pollutants, and improper treatment can cause water pollution. The regular replacement of catalysts also generates a large amount of hazardous waste, increasing the difficulty and cost of solid waste disposal. At the same time, this process uses a segmented treatment method for desulfurization and denitrification, which not only prolongs the flue gas treatment process and increases the equipment footprint, but also makes it difficult to achieve simultaneous and efficient removal of multiple pollutants, limiting the overall treatment efficiency.

[0006] There are a large number of coal-related industries and hazardous waste disposal industries, if all use the current high-cost treatment process, it will cause incalculable losses to the national economy. According to incomplete statistics, only according to the number of 75 tons per hour level boiler, the annual economic burden of the whole country in the aspect of flue gas treatment reaches hundreds of millions of yuan. This situation not only increases the burden of enterprises, but also is not conducive to the popularization and application of environmental protection technology and the realization of pollutant emission reduction target. Therefore, it is urgent to develop a new type of flue gas purification technology with simple process, low operating cost and good treatment effect, to solve the many problems existing in the existing technology and promote the progress of air pollution control technology in China. SUMMARY

[0009] Further, the magnetic alloy steel structure is composed of an alloy material composed of at least two elements of iron, aluminum, chromium, zinc and nickel.

[0010] Further, the alloy spectrum energy net is composed of an alloy material composed of iron, aluminum, chromium, zinc and nickel elements; according to the types of waste gas in the flue gas to be treated, the alloy element ratio of the alloy spectrum energy net is set, and the alloy element ratio of different layers of the alloy spectrum energy net can also be set.

[0011] Further, the two alloy spectral regions are a first alloy spectral region and a second alloy spectral region, the first alloy spectral region and the second alloy spectral region are diagonally distributed, and the two flue gas passage regions are diagonally distributed.

[0012] Further, the spectral energy molecular sieve is made of glass fiber material.

[0013] Further, the hollow thermal insulation layer is filled with perlite thermal insulation material.

[0014] Further, the tower body bottom outer side is provided with an ion furnace structure, the ion furnace structure comprises: an ion furnace shell; an ion furnace refractory insulation layer arranged in the ion furnace shell; an oxygen-free light source origin arranged in the ion furnace refractory insulation layer; an ion furnace mounting base, and the ion furnace shell is fixed on the ion furnace mounting base.

[0015] Further, a heat transfer structure is further included, the heat transfer structure connects the ion furnace structure and the tower body interior, and the heat transfer structure comprises: an alloy ion net; a Tr passage; an alloy ion rod arranged in the Tr passage.

[0016] Further, the shell steel structure is divided into multiple sections along the tower body height direction, adjacent sections are connected through outer cylinder flanges, and the outer cylinder flanges are arranged on the outer side of the shell steel structure.

[0017] Further, the alloy spectral energy net is arranged in 3-45 layers along the tower body height direction.

[0018] Advantages of the present application: 1. The present application adopts a dry adsorption process, which fundamentally simplifies the traditional flue gas purification process. The traditional desulfurization and denitrification catalytic split-flow neutralization method needs to be configured with a powder spraying structure, a water circulation system, a catalyst spraying system, an ammonia water spraying system, a dehydration device and a large number of auxiliary facilities, and the process is complicated. Without these complicated facilities, the present application can realize flue gas purification through the magnetic alloy steel structure and the alloy spectral energy net in the squirrel cage type tower core structure, significantly reducing the basic investment in equipment. At the same time, the present application does not need to use catalysts, CaO powder, ammonia water and other chemical reagents, avoiding the continuous chemical purchasing cost, and can save a lot of operation cost, having significant economic benefits.

[0019] 2. This invention utilizes a multi-layered magnetic alloy steel structure with varying proportions and an alloy spectral energy grid. By leveraging the spectral energy and strong magnetic field generated at high temperatures by multi-element alloys such as iron, aluminum, chromium, zinc, and nickel, it can simultaneously target SO2, SO3, H2S, and NO. x This system treats various harmful gases, including CO, through cracking and adsorption, achieving comprehensive one-time treatment. Unlike traditional processes, it eliminates the need for separate desulfurization and denitrification steps, significantly improving treatment efficiency. The squirrel-cage tower core structure is divided into four equal parts circumferentially, including two diagonally distributed alloy spectral regions and two diagonally distributed flue gas channel regions. Flue gas undergoes multi-layer circulation within the tower, ensuring full contact with the alloy surface, resulting in high treatment efficiency. The structure is compact and requires minimal floor space. Different alloy ratios can be optimized according to the characteristics of the target pollutants, making it highly adaptable and suitable for various coal-related emission industries, such as coal-fired power plants and hazardous waste disposal.

[0020] 3. This invention offers both a simple process and extremely convenient management and maintenance. The entire adsorption tower has no moving parts, eliminating the need for frequent catalyst replacements, minimizing maintenance workload, and saving on labor costs and downtime. The spectroscopic molecular sieve is made of glass fiber, which is characterized by high temperature resistance and good chemical stability. After heating stops, the magnetic field disappears, and the adsorbate automatically falls to the storage tank at the bottom of the tower. No replacement of the adsorption material is required, allowing for long-term reuse and further reducing operating and maintenance costs.

[0021] 4. This invention employs a dry process, eliminating the use of water as a medium and avoiding wastewater discharge problems. It also eliminates the generation of solid waste such as desulfurization gypsum. The mass of the detached adsorbate is extremely small, only one ten-millionth of the original mass, making it easy to collect and process in a storage facility, effectively preventing secondary pollution. This invention utilizes the heat from the flue gas itself and the auxiliary heat energy provided by the ion furnace to achieve molecular pyrolysis under high-temperature conditions. The heat released during the combustion of hydrogen and oxygen during pyrolysis can compensate for some of the energy loss, resulting in high energy utilization efficiency. Through this highly efficient dry adsorption process, with no chemical reaction byproducts and no additional energy consumption, it effectively achieves the environmental goal of reducing carbon emissions.

Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0025] Example 1: As Figures 1 to 3 As shown, this embodiment provides an internal circulation magnetic field dry adsorption tower, including a tower body, an outer steel structure 1, an air-insulated layer 2, a cage-type tower core structure, a magnetic alloy steel structure 3, an alloy spectral energy mesh 4, a spectral energy molecular sieve 5, a central channel 6, a storage tank 7, and an ion furnace structure.

[0026] like Figure 1 As shown, the tower body is a cylindrical vertical structure, with the outer steel structure 1 forming the outer wall of the tower body and providing structural support for the entire adsorption tower. An insulating layer 2, filled with perlite insulation material, is installed inside the outer steel structure 1 to reduce heat loss and maintain the operating temperature inside the tower. The outer steel structure 1 is divided into multiple sections along the height of the tower body, with adjacent sections connected by outer cylinder flanges 8. The outer cylinder flanges 8 are located on the outside of the outer steel structure 1, facilitating the segmented manufacturing, transportation, and on-site assembly of the adsorption tower.

[0027] like Figure 3 As shown, the cage-like tower core structure is located inside the insulating layer 2. The cage-like tower core structure is divided into four equal parts along its circumference, including two opposing alloy spectral regions and two opposing flue gas channel regions. The two alloy spectral regions are the first alloy spectral region and the second alloy spectral region, which are diagonally distributed. The two flue gas channel regions are also diagonally distributed, and the alloy spectral regions and flue gas channel regions are arranged alternately, forming a structure resembling a hamster cage.

[0028] In the alloy spectrum region, there is a magnetic alloy steel structure 3 and an alloy spectrum energy net 4. The magnetic alloy steel structure 3 is composed of an alloy material composed of at least two elements of iron, aluminum, chromium, zinc, and nickel, serving as the main skeleton support structure. The alloy spectrum energy net 4 is also composed of an alloy material composed of iron, aluminum, chromium, zinc, and nickel elements, in a net structure, arranged on the magnetic alloy steel structure 3. According to the types of waste gas in the flue gas to be treated, the alloy element ratio of the alloy spectrum energy net 4 is set, and different alloy element ratios can be set for different layers of the alloy spectrum energy net 4. The spectrum energy molecular sieve 5 is arranged on the alloy spectrum energy net 4, which is made of glass fiber material, has the characteristics of high temperature resistance, good chemical stability, and porous structure, and provides a large number of adsorption sites for single atom substances.

[0029] The central channel 6 is arranged at the center axis position of the tower body, penetrating the tower body up and down, to provide a channel for flue gas flow and heat transfer. The storage library 7 is arranged in the inner cavity of the tower body at the bottom, for collecting the adsorbed substances falling off. The flue gas inlet is arranged at the bottom of the tower body, and the flue gas outlet is arranged at the top of the tower body, forming a flue gas flow path from bottom to top.

[0030] As shown in Figure 2 The ion furnace structure is provided outside the bottom of the tower body, including an ion furnace shell 9, an ion furnace refractory insulation layer 10, an oxygen-free light source origin 11, and an ion furnace mounting base 12. The ion furnace shell 9 provides external protection for the ion furnace, and the ion furnace refractory insulation layer 10 is arranged inside the ion furnace shell 9, having good heat preservation performance. The oxygen-free light source origin 11 is arranged inside the ion furnace refractory insulation layer 10, serving as the actual heat source to provide the necessary heat energy for the entire adsorption tower, maintaining the working temperature in the tower within the range of 300-800℃. The ion furnace shell 9 is fixed on the ion furnace mounting base 12, which serves as the foundation support of the entire adsorption tower.

[0031] The ion furnace structure is connected with the tower body inside through a heat transfer structure. The heat transfer structure includes an alloy ion net 13, a Tr channel 14, and an alloy ion rod 15. The alloy ion net 13 is arranged below the storage library 7, the Tr channel 14 connects the storage library 7 and the ion furnace, and the alloy ion rod 15 is arranged in the Tr channel 14. Heat is generated from the oxygen-free light source origin 11, and is transferred to the inside of the tower body through the ion furnace refractory insulation layer 10, the Tr channel 14, the alloy ion rod 15, and the alloy ion net 13, ensuring that the temperature and pressure in the tower meet the working requirements.

[0032] The working principle of the present application is based on the basic theory of quantum mechanics and quantum chemistry. The magnetic alloy steel structure 3 and the alloy spectrum energy network 4 are composed of multi-element alloy materials such as iron, aluminum, chromium, zinc, nickel, etc. These alloy materials can generate strong magnetic fields and specific wavelength spectrum energy under the high temperature conditions provided by the ion furnace. These different wavelength ultraviolet short color spectrum has a bond breaking effect on various compounds in the flue gas. When the flue gas containing SO2, SO3, H2S, CO, NO x After the flue gas containing harmful substances such as SO2, SO3, H2S, CO, NO

[0033] The design of the squirrel cage tower core structure makes the flue gas form an internal circulation flow in the tower. The flue gas rises through the two diagonally distributed flue gas passage areas, and continuously contacts the first alloy spectrum area and the second alloy spectrum area during the rising process, realizing multiple cycle treatment. The alloy ratio of the first alloy spectrum area and the second alloy spectrum area can be designed to be different, so as to produce targeted treatment effect on different types of pollutants. This four-equal-part structure design not only ensures the smoothness of the flue gas flow, but also maximizes the gas-solid contact area and contact time, and improves the treatment efficiency.

[0034] Example 2: Bond breaking treatment of water molecules.

[0035] The water content in harmful flue gas is large, that is, the water component is dominant. The H2O molecule cracking process is as follows: ; wherein when the hydrogen atom is cracked into two electrons at high temperature, the hydrogen atom reversely reacts into a hydrogen atom group to form a hydrogen molecule H2. At this time, the problem is that H2 and O2 will spontaneously ignite when they meet. When the hydrogen atom is excessive, the pressure reaches a certain value, which will produce a terrible phenomenon, that is, hydrogen atom explosion. But there is no need to worry about this, as long as the external heat supply flue gas supply temperature and the internal hydrogen and oxygen spontaneous ignition supply temperature are balanced during design. At the same time, the flow of the client's treatment flue gas and the water content of the flue gas are controlled. The size of these data is used to determine the total amount of memory of the "RXG" internal circulation flue gas comprehensive adsorption tower, so as to ensure the safety factor of the patented product.

[0036] The approximate composition of the primary harmful irritating gas is mainly gas. Among them, there are small molecular inorganic substances such as SO2, SO3, H2S, CO, CO2, hydrochloric acid, NH3, XCO2, XNO3, etc., high molecular compounds such as CH4 waste methane, butadiene, benzene compounds, and biological putrid macromolecular chain compounds, etc. These "shadowless" substances, whether they are shadowless or shadowless, gradually lose their energy during the high-temperature cracking process in the tower, leaving only single-element atomic crystal substances in the tower, which become the residual substances of the homogeneous particle system.

[0037] H2O from entering the RXG tower at the first layer: ; upper layer: .

[0038] At this moment, a large amount of hydrogen gas and oxygen gas are generated in the tower, and hydrogen gas produces a self-ignition phenomenon under the assistance of oxygen (note that at this time the hydrogen and oxygen combustion is not normal combustion but a heat release reaction under high temperature and high pressure to lose energy). It just fills the energy loss at the bottom of the tower due to the cracking of the substance valence bond. The reaction of the cracked and burned substance element atomic single crystal is continuous and continuous. In the RXG tower, no matter what the structure of the substance molecule is, it is like being destroyed.

[0039] Example 3: Adsorption of sulfur dioxide and other waste gas.

[0040] For sulfur dioxide, ; in the case of the outer electron shell n+1: ; in the case of the outer electron shell n+2: ; At this time, oxygen and single crystal part ways, O2 participates in hydrogen combustion, and single crystal sulfur: , single crystal substance is precipitated outside, and the weight of the tower is one ten-thousandth of the original compound.

[0041] For methane, (Note: 4H -e is in the special case of quantum theory); For hydrogen sulfide, ; in the higher layer of the electron buffer zone ; or ( ), at this time the thermal motion in the RXG tower is the explosion of hydrogen and oxygen, and the element atomic crystal reaction of the substances in the tower is continuous. Even macromolecular biological compounds, such as carbohydrates, also disappear in this reaction process, leaving only one ten-thousandth of the "Rydberg" law.

[0042] Example 4: Post-processing.

[0043] When heat exchange between the inside and outside of the tower ceases, the strong magnetism on the alloy spectral energy grid 4 immediately disappears. At this time, the single-atom substances adsorbed on the magnetic alloy steel structure 3 automatically detach from the structure and settle into the storage tank 7 at the bottom of the tower. The mass of these adsorbed substances has been greatly reduced. According to the neutrino mass theory, the mass of a single-atom substance is only one ten-millionth of the original molecular mass of the compound. Therefore, the amount of substance collected in the storage tank 7 is very small, making it easy to clean regularly and preventing secondary pollution.

[0044] The clean flue gas, after undergoing multiple treatment processes, is discharged from the flue gas outlet at the top of the tower. Because the harmful substances in the flue gas have been broken down and adsorbed, the discharged flue gas mainly consists of harmless gases such as nitrogen and oxygen, all of which meet ultra-low emission standards.

[0045] The ion furnace structure continuously provides heat energy to the tower through the heat transfer structure, ensuring that the temperature inside the tower is maintained within the working range of 300-800℃, thus guaranteeing that the magnetic alloy steel structure 3 and the alloy spectral energy grid 4 can continuously generate spectral energy and magnetic field.

[0046] The dry process employed in this invention completely eliminates the use of water and any chemical reagents, avoiding the consumption of catalysts, ammonia, CaO powder, etc., as well as the generation of wastewater and solid waste, which are common in traditional processes. The entire treatment process relies on physical principles (high temperature, spectral energy, magnetic field) to achieve molecular cleavage and adsorption. The process is simple, has low operating costs, and offers significant environmental benefits.

[0047] Example 5: A building materials company in Inner Mongolia applied the RXG internal circulation magnetic field dry adsorption tower of the present invention for flue gas treatment.

[0048] The company's flue gas volume is equivalent to the boiler fuel gas volume of 50t / h, which is 50,000m³. 3 The RXG internal circulation magnetic field dry adsorption tower used for flue gas treatment is Φ1.8×12m. The alloy energy dispersive spectroscopy (EDS) grid for treating the flue gas is arranged in 18 layers along the height of the tower. The EDS grid is composed of five elements: iron, aluminum, chromium, zinc, and nickel. The iron content is 83.53%, aluminum 1.42%, chromium 1.42%, zinc 2.42%, and nickel 2.42%, with the remainder being carbon, sulfur, manganese, copper, etc. The main components of the flue gas are sulfur, nitrogen oxides, and odorous gases. Experimental tests were conducted, and the results are as follows: The chemical composition of the company's coal is shown in Table 1.

[0049] Table 1 Chemical composition of coal The bituminous coal of the company is mainly low metamorphic bituminous coal with low sulfur, low ash and high volatile matter, which needs to be adapted through clean technology to balance energy benefit and environmental protection demand. The RXG internal circulation magnetic field dry adsorption tower of the application is installed, at about 10 o'clock on May 20, 2025, the equipment is debugged, and the RXG internal circulation magnetic field dry adsorption tower waste gas exhaust port is sampled and detected, and the detection results are shown in table 2 and table 3.

[0050] Table 2: flue gas parameters of RXG internal circulation magnetic field dry adsorption tower Table 3: detection results of RXG internal circulation magnetic field dry adsorption tower waste gas exhaust port Note: "L" means that the detection result is lower than the detection limit.

[0051] From the results of table 2 and table 3, it can be seen that the application has a significant purification effect on harmful gases. The detection data of sulfur dioxide and nitrogen oxides are at a low level, which proves that the alloy spectrum energy net can effectively crack the chemical bonds of SO2, NO x and other harmful molecules under the action of high temperature spectrum energy and strong magnetic field, so that they are decomposed into monatomic substances and adsorbed by spectrum energy molecular sieve. The detection results of odor concentration show that various compounds in the primary harmful pungent gas, including sulfides, nitrogen oxides and other organic compounds, are effectively removed after being treated by multiple layers of circulation in the tower. The detection data at two different time points remain stable, which shows that the application has good running stability and repeatability of treatment effect.

[0052] Without using any catalyst, ammonia water, CaO powder and other chemical reagents, the application can realize the synergistic and efficient treatment of various harmful gases only by relying on physical principles (high temperature, spectrum energy and magnetic field), which verifies the feasibility and effectiveness of the dry adsorption process of the application, and has the significant advantages of simple process, low operating cost and no secondary pollution compared with the traditional wet process.

[0053] Finally, it should be pointed out that the above-mentioned examples only express several embodiments of the application, and are not used to limit the application. Any modification, equivalent replacement, improvement, etc. made by those skilled in the art without departing from the concept of the application should be included in the protection scope of the application. Therefore, the protection scope of the application patent should be subject to the appended claims.
