Description

Technical Field

[0001] This invention relates to the field of industrial gas energy saving and combustion activation technology, specifically to a method and device for deep activation and energy saving of natural gas using multi-element catalytic composite magnetization. Background Technology

[0002] Natural gas, as a core clean energy source for industry, has a stable molecular structure of its main component, methane (CH4). The CH chemical bonds are highly energized and strongly bonded, making it difficult for methane molecules to be fully decomposed during conventional combustion. This results in prominent problems such as incomplete combustion, low thermal efficiency, significant energy waste, severe carbon buildup, and excessive CO / nitrogen oxide emissions in the exhaust gas.

[0003] Existing natural gas energy-saving technologies have significant technical shortcomings:

[0004] Limitations of single magnetization technology: It relies solely on the physical polarization of molecules by magnetic fields, which can only break up molecular clusters and cannot weaken CH chemical bonds. The activation depth is insufficient, the energy saving is only 5%–10%, and the effect is unstable.

[0005] The drawbacks of single catalytic technology are: the lack of a pre-magnetic field to disperse the catalyst, severe aggregation of methane molecules, small catalytic contact area, uneven reaction, low catalytic efficiency, and easy poisoning, shedding, and short lifespan of the catalyst.

[0006] Gas-free flow stabilization design: Turbulent gas flow and severe short circuits result in short residence time of activated molecules, easy re-agglomeration, and a significant reduction in activation effect.

[0007] Poor device adaptability: The structure is fixed and cannot be adapted to combustion equipment with different pipe diameters, flow rates, and tonnages, resulting in weak versatility;

[0008] The catalyst loading process is crude: direct coating or simple adhesion makes it easy to fall off when washed by high-temperature gas, resulting in poor long-term stability and high maintenance costs.

[0009] Disadvantages of active design: Some devices require external power supply and mechanical drive, which increases energy consumption, has a high failure rate, and is complex to maintain. To address this, a multi-element catalytic composite magnetization deep activation energy-saving method and dedicated device for natural gas is proposed. Summary of the Invention

[0010] In view of this, the present invention provides a method and device for deep activation and energy saving of natural gas by multi-element catalytic composite magnetization, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0011] The technical solution of the present invention is implemented as follows: a multi-element catalytic composite magnetization natural gas deep activation energy-saving device, including a catalytic reaction chamber, wherein the outer wall of the catalytic reaction chamber is connected to an air inlet connector;

[0012] The air intake connector is equipped with multiple sets of annular magnets, which are stacked with the same pole along the airflow axis. The bottom of the air intake connector is connected to a shower head.

[0013] The catalytic reaction chamber is filled with a catalytic carrier, and the porous ceramic material is loaded with multi-element catalytic materials on its surface. The porous ceramic material can be in various shapes such as spherical or ring-shaped.

[0014] More preferably, one end of the air inlet connector is equipped with a first flange, the bottom of the catalytic reaction chamber is connected to an air outlet connector, and the bottom of the air outlet connector is connected to a second flange.

[0016] More preferably, the catalyst support is a porous ceramic cone, a porous ceramic cone column, or a cone-shaped component with grooves on its surface.

[0017] A method for deep activation and energy saving of natural gas using multi-element catalytic composite magnetization includes the following steps:

[0018] S1: Magnetic field pretreatment: Natural gas is introduced into the magnetization cavity and penetrated bidirectionally by the annular magnetic field, breaking up methane molecule clusters and weakening CH chemical bonds; the annular magnetic field is formed by multiple sets of annular magnets arranged axially with the same poles.

[0019] S2: Gas Dispersion and Guidance: The pre-treated natural gas is tangentially introduced into the gas dispersion and guidance cavity, and the gas is dispersed along the conical inner core to prolong the gas residence time;

[0020] S3: Deep catalysis: The diverted natural gas is introduced into the catalytic reaction chamber and fully contacts the porous ceramic material loaded with multi-element catalytic materials to further activate methane molecules;

[0021] S4: Combustion Application: The activated natural gas is delivered to the combustion equipment for complete combustion.

[0022] More preferably, the annular magnet is a neodymium magnet with a magnetic field strength of not less than 3000 gauss; natural gas flows bidirectionally from both the inner hole of the annular magnet and the annular gap between the annular magnet and the inner wall of the pipeline.

[0023] More preferably, the multi-element catalytic material is fixed to the surface of the porous ceramic material through the following loading process:

[0024] ①Preparation of suspension: Disperse the multi-element catalytic powder in pure water, add silica sol as a binder, and stir evenly to form a suspension;

[0025] ② Carrier pretreatment: Clean and dry the porous ceramic material;

[0027] ④ Drying and sintering: The impregnated porous ceramic material is dried and sintered at high temperature to firmly load the multi-element catalytic material onto the surface.

[0028] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0029] I. This invention combines magnetic field dispersion, gas dispersion and stabilization, and multi-element catalysis, achieving energy savings of 8%~15%, far exceeding single technologies. The ≥3000 Gauss neodymium magnet provides bidirectional and uniform penetration, effectively weakening CH chemical bonds and resulting in high activation efficiency. Dispersing the gas extends the residence time, preventing activated molecule agglomeration and ensuring complete catalytic reaction. The catalyst is firmly loaded, resistant to high temperatures and erosion, with a lifespan of ≥2 years and low maintenance costs.

It is suitable for temperatures ranging from -20℃ to 120℃, has a low failure rate, uses flange connections, and is compatible with boilers / kilns of different pipe diameters, flow rates, and tonnages. It is easy to install, and complete combustion reduces CO and nitrogen oxide emissions, resulting in significant environmental benefits. It can be directly connected to pipelines without requiring equipment modifications, and only periodic cleaning of the catalyst is needed in the later stages.
