Description

[Technical Field]

[0001] This invention relates to the field of diesel fuel filtration technology, and in particular to a honeycomb core enriched with ion molecular sieves and its manufacturing method. [Background Technology]

[0002] Diesel fuel quality and combustion efficiency significantly impact engine performance and emissions during use. Traditional diesel filtration methods primarily focus on removing impurities and moisture. For example, patent application CN201120453950.1 discloses a diesel filter comprising a housing with an inlet on one side. The inlet is connected to a filter chamber within the housing via an inlet pipe. The filter chamber contains a sealed filter element, which includes a filter screen and a filter element cavity. The filter element cavity is connected to an outlet via an oil storage chamber, and a magnet is installed within the filter chamber. Such filters remove dust, impurities, and gum from the diesel fuel, refining it, but their effect on improving the catalytic activity of the diesel is limited. While some related technologies on the market attempt to improve diesel performance, they suffer from high costs, unstable filtration effects, and short service life. Therefore, developing a highly efficient, stable, and cost-effective ion molecular sieve diesel filter is of significant practical importance. [Summary of the Invention]

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a nutrient-enriched molecular sieve honeycomb core and its manufacturing method.

[0004] A nutrient-enriched molecular sieve honeycomb core comprises the following components by mass: 30 parts tourmaline powder, 40 parts low-silicon ZSM-5 molecular sieve, 15 parts 13X, 10 parts cerium oxide, and 5 parts high-silicon.

[0005] Preferably, the particle size of the various raw materials is as follows: tourmaline powder 800 mesh, low-silicon ZSM-5 molecular sieve 800 mesh, 13X900 mesh, cerium oxide 800 mesh, and high-silicon 900 mesh.

[0006] A method for manufacturing a honeycomb core of ion-enriched molecular sieves includes the following steps:

[0007] Step 1: Mix 30 parts tourmaline powder, 40 parts low-silica ZSM-5 molecular sieve, 15 parts 13X, 10 parts cerium oxide, and 5 parts high-silica powder thoroughly. Then add 45 parts alkaline silica sol for a second mixing of powder and liquid materials until a paste-like material is formed.

[0008] Step 2: The clay-like material is pressed into shape using a special honeycomb structure mold, demolded, and air-dried for 12 hours, then sintered at high temperature for 24 hours, and then air-dried for another 12 hours to form a honeycomb core board.

[0009] Step 3: Mix 40 parts tourmaline powder, 50 parts low-silicon ZSM-5, and 10 parts cerium oxide according to weight to make a metal mesh material for spraying.

[0010] Step 4: Mix the metal mesh material powder and plastic powder at a mass ratio of 25:75 to form oxygen-rich ion molecular sieve plastic powder;

[0011] Step 5: Weave the 0.3 mm diameter iron wire into a 1 mm x 1 mm mesh, and then make this mesh into a circular mesh with a diameter of 98 mm and a height of 210 mm.

[0012] Step Six: Place the formed circular mesh on the electrostatic spraying line, and spray the oxygen-rich ion molecular sieve powder onto the surface of the metal mesh using electrostatic spraying. After spraying, it is cured at high temperature for forty minutes to form the outer skeleton of the oxygen-rich ion molecular sieve metal mesh honeycomb core.

[0013] Step 7: Take ten honeycomb core panels, fix a layer of blue water-absorbing composite fiber felt between two adjacent honeycomb core panels, and fix a layer of blue water-absorbing composite fiber felt at both ends of the honeycomb core panels to make a honeycomb core.

[0014] Step 8: The outer skeleton of the oxygen-enriched molecular sieve honeycomb core is fitted onto the honeycomb core body and glued to the inside of the upper and lower end caps with AB glue to make an oxygen-enriched molecular sieve honeycomb core.

[0015] Preferably, the high-temperature sintering temperature in step three is 600 degrees Celsius.

[0016] Preferably, the special honeycomb structure mold in step two has a diameter of 95 mm, a thickness of 15 mm, and a fineness of 100 mesh.

[0017] Compared with existing technologies, the present invention has the following advantages:

[0018] 1. Multi-layer filtration structure: The filter adopts a multi-layer filtration structure combining honeycomb core panels and composite fiber filter felt. The porous material of the honeycomb core panels can adsorb harmful substances such as large molecular impurities, colloids, and asphalt in diesel fuel, while the composite fiber filter felt can effectively intercept fine particulate impurities such as dust and iron filings, achieving all-round filtration of various impurities in diesel fuel. The high filtration accuracy can significantly improve the cleanliness of diesel fuel, reduce the wear and clogging of precision components such as engine injectors and plungers caused by impurities, and extend engine life.

[0019] 2. Targeted adsorption: The low-silicon ZSM-5 molecular sieve and 13X molecular sieve materials in the oxygen-rich ion molecular sieve honeycomb core have good adsorption performance for harmful substances such as sulfides and nitrogen oxides in diesel fuel. They can effectively reduce the sulfur and nitrogen content in diesel fuel, reduce the generation of harmful gases during combustion, reduce exhaust emissions pollution, and make the engine more compliant with environmental protection requirements.

[0020] 3. Water-absorbing fiber filter felt: Multiple blue water-absorbing composite fiber filter felts can efficiently absorb moisture in diesel fuel during the filtration process. Their excellent water absorption performance can reduce the moisture content in diesel fuel to an extremely low level, preventing moisture from entering the engine combustion chamber and avoiding problems such as engine knocking, power reduction, and difficulty starting caused by moisture. At the same time, it reduces the corrosion of internal engine parts by moisture, ensuring the normal operation of the engine.

[0021] 4. Synergistic water removal effect: While adsorbing impurities, the oxygen-rich ion molecular sieve honeycomb core also adsorbs some of the water dissolved in diesel fuel. In combination with the water-absorbing fiber filter felt, it further enhances the water removal effect of the filter, ensures the dryness of diesel fuel, and improves the combustion efficiency and power performance of the engine.

[0022] 5. Oxygen-rich ion release: Under specific conditions, materials such as tourmaline powder can release oxygen-rich ions. These ions, once introduced into diesel fuel, can improve its oxidative stability and promote complete combustion. Completely combusted diesel fuel releases more energy, thereby increasing engine power output while reducing carbon deposits and harmful gas emissions from incomplete combustion. This results in smoother, more efficient engine operation, lower fuel consumption, and reduced maintenance costs.

[0023] 6. Improve diesel quality: Through multiple functions such as adsorbing impurities, removing moisture, and releasing oxygen-rich ions, the filter can effectively improve the overall quality of diesel, making the diesel closer to the physicochemical properties required for ideal combustion, providing the engine with better fuel, and improving engine performance and economy.

[0024] 7. High-temperature sintered material: The honeycomb core is sintered at 600 degrees Celsius, giving it high mechanical strength and chemical stability. It can withstand the pressure and impact generated during diesel filtration, and is not easily deformed or damaged, ensuring the stability and reliability of the filter during long-term use.

[0025] 8. Catalytic Stabilizing Materials: The addition of catalytic stabilizing materials such as cerium oxide not only helps in the adsorption and decomposition of impurities, but also improves the anti-aging properties of materials such as molecular sieves, extending their service life. This means that the filter does not need to be replaced frequently under normal operating conditions, reducing the user's operating costs and maintenance workload.

[0026] 9. Honeycomb structure design: The honeycomb structure of the honeycomb core has good permeability, which can ensure the smooth flow of diesel fuel during the filtration process, reduce flow resistance, and avoid problems such as insufficient fuel supply to the engine or abnormal increase in fuel system pressure due to excessive pressure drop, thus ensuring normal fuel supply to the engine and stable operation of the fuel system.

[0027] 10. Reasonable pore size and material matching: The pore size of the honeycomb core is carefully designed to match the viscosity and flowability of diesel fuel. Combined with the appropriate porosity of the composite fiber filter felt, it not only ensures the filtration effect but also effectively controls the pressure drop, achieving a good balance between filtration performance and permeability, so that the filter can maintain good working condition under different operating conditions.
