Description

Environmental protection and emission reduction fuel manufacturing method

The present invention relates to an environmentally friendly fuel manufacturing method, in particular to a method that combines various mechanical methods to refine water and fuel and then allows the fuel to completely coat and mix the water into an environmentally friendly emission-reducing fuel. It is also possible to mix emission-reducing agents into the water first. The fuel is refined and blended together to produce environmentally friendly and emission-reducing fuels.

Due to the increasing severity of global warming, many countries have set targets and related supporting measures to reduce the emission of various air pollutants. my country has not stayed aside. The Environmental Protection Agency recently set a boiler air pollutant emission standard, requiring private industrial boilers to reduce the emissions of particulate pollutants by 70%, reduce the emissions of sulfur oxides by 83%, and reduce the emissions of nitrogen oxides by 60% by 2020. The emission of natural gas has made it difficult for manufacturers who cannot switch to using natural gas as fuel to scream and cannot meet the government’s predetermined emission reduction targets as scheduled. In addition, my country’s natural gas needs to be imported by large ships from abroad. If a typhoon or other force majeure causes ships to be unable to call at the port, there is a risk of interruption of fuel sources; large-scale high-pressure containers are required to store natural gas for centralized storage, which also increases public safety risks. From the perspective of decentralization of energy reserves, it is also a fuel with disadvantages. Due to the higher ignition point of heavy oil fuel, it is safer in transportation and storage than natural gas, liquefied petroleum gas, gasoline and diesel. It is not prone to accidents such as a large fire caused by a tank truck accident. The cost of heavy oil fuel is also higher than that of natural gas, liquefied petroleum gas and Gasoline and diesel are much cheaper, so if we can economically reduce the emissions of heavy oil fuels, it can be a big help for my country, which is mainly small and medium-sized enterprises, to reduce pollution emissions.

Generally, the way for boilers to reduce nitrogen oxide emissions is shown in Figure 3. Injecting a chemical agent B1, such as an aqueous solution of urea or ammonia, as a reducing agent above the flame of boiler B to react with nitrogen oxides and neutralize the smoke. Nitrogen oxides in the gas are reduced to harmless N ₂ and H ₂ O; however, this method has a high cost and is difficult for ordinary small and medium-sized enterprises to load. Ammonia is also toxic and corrosive, and it is more dangerous to store and use. Need to find another cheaper way to reduce nitrogen oxide emissions. The sulfur oxide is processed by another desulfurization equipment.

In addition to switching to natural gas as fuel, there is also a method of reducing emissions by adding water to fuel. Water added fuel refers to a mixture of water in fuel oil, which can greatly reduce the amount of fuel used and reduce CO ₂ ( Carbon dioxide) is a fuel that is beneficial to the environment. Since complete combustion can be expected, the amount of air used for combustion can also be reduced to a considerable extent. Along with this, the generation of nitrogen oxides or particulate matter (PM) can also be suppressed, which has the effect of environmental protection and emission reduction. The Republic of China Patent Certificate No. I621705 discloses a method and device for producing water-filled fuels, which can produce water-filled fuels that can be stored stably. However, complicated equipment and methods are still required, and the water source needs to be processed into soft water first, which increases costs.

In view of this, the inventors devote themselves to research and design, and hope to provide a method that can easily produce environmentally friendly and emission-reducing fuels, which is the motive of the invention.

The main purpose of the present invention is to provide a method for economically manufacturing environment-friendly and emission-reducing fuel.

Therefore, the environmental protection and emission reduction fuel manufacturing method of the present invention includes sequential processing of water and fuel separately. The sequential processing includes ore activation, high-pressure impact, shear effect, high-speed injection, and ultrasonic processing; and the sequential processing is performed. The water is mixed with fuel for integrated mechanical treatment to allow the fuel to completely coat the water to obtain environmentally friendly and emission-reducing fuel. The integrated mechanical treatment includes high-speed shearing, high-speed injection, high-pressure homogenization, vortex mixing and ultrasonic treatment. Water can come from various water sources such as tap water, groundwater or organic wastewater. The fuel can be heavy oil, kerosene, diesel and other oil products. The volume percentage of water in environmentally friendly emission reduction fuels is 5-45%, and the average particle size of water is 2~8um, can make the fuel and water not separate. The water can be mixed with the medicament before the sequencing treatment. The medicament can contain alcohols, enzymes, urea and other agents that help reduce nitrogen oxides to enhance the effect of reducing nitrogen oxide emissions. The boiler does not need to use equipment for spraying chemical reduction agents, it also reduces the burden on the back-end filtering equipment, and greatly reduces the cost of emission reduction equipment.

Urea is a non-toxic and harmless chemical with no possibility of explosion and no danger at all. Therefore, it is very suitable as a reducing agent for reducing nitrogen oxides. When liquid ammonia or ammonia water is used, it will increase the risk of industrial safety.

Generally, boilers are equipped with an atomizing oil gun to atomize the fuel once, and when the environmentally friendly emission reduction fuel is burned, the vaporization point of water (100℃) is lower than that of ordinary fuels. The order of water molecules contained inside is The fuel is fully gasified and burst, and the fuel is atomized twice into nano-level fine particles to make the combustion more complete. The boiler is not easy to accumulate carbon, which can save fuel by more than 10%, and the chemicals contained in the water, such as urea, can also be sufficient It completes the reaction with the nitrogen oxides in the exhaust gas to reduce the emission of nitrogen oxides.

In order to further understand the features, characteristics and technical content of the present invention, please refer to the following detailed description of the present invention.

Please refer to the first and second figures. The above-mentioned figures illustrate the environmentally friendly and emission-reducing fuel manufacturing method of the present invention, which includes the sequential processing of water and fuel S1, S1A, wherein the sequential processing S1, S1A includes ore activation, High-pressure impact, shearing effect, high-speed injection, and ultrasonic treatment; and the integrated mechanical treatment S2 is performed by mixing the water and fuel in the sequenced section, and then the water is completely covered by the fuel to obtain environmentally friendly and emission-reducing fuel. Mechanical treatment S2 includes high-speed shearing, high-speed jetting, high-pressure homogenization, vortex mixing and ultrasonic treatment.

The source of water can be various water sources such as tap water, groundwater or organic wastewater, and the water can be subjected to a chemical mixing step S1B before sequential treatment. The medicament can include alcohols, enzymes and urea. The medicament can be strengthened after being dissolved in water. The effect of removing nitrogen oxides in combustion exhaust gas.

In Figure 4, when the present invention is used in boiler B, it directly replaces fuel input without using additional spraying equipment, which can greatly reduce the cost of building emission reduction equipment. Moreover, after using the environmentally friendly and emission-reducing fuel of the present invention, the burden of the filter screen for filtering particulate pollutants at the back end can also be reduced, further reducing the maintenance cost of the filter device.

In the fifth figure, a general boiler is equipped with an atomizing oil gun to atomize fuel C once. The environmentally friendly emission reduction fuel C1 produced by the present invention is atomized into the combustion chamber by a nozzle once and then starts to heat up. The internal moisture C2 exceeds 100 After ℃, it will start to vaporize and expand, and when the water vapor pressure is higher than the surface tension of the C1 droplets, the C1 droplets will explode and split into several particles, that is, secondary atomization occurs and the water contained inside Molecular sequencing produces full gasification and explosion, and the fuel is atomized into nano-level fine particles, which makes the diameter of C1 droplets of the environmentally friendly emission reduction fuel smaller, increases the surface area that can be reacted, promotes more complete combustion, and improves the fuel. The combustion degree and efficiency of the boiler are not easy to accumulate carbon, and the emission of carbon particles is reduced. If the environmentally friendly emission reduction fuel C1 with mixed chemical C3 is used, the chemical C3 is also dispersed in the entire combustion chamber during the secondary atomization stage, which can fully react with nitrogen oxides and greatly reduce nitrogen oxide emissions to use urea Take the medicine C3 as an example. The reaction at this time is as follows: (NH ₂ )CO → 2NH ₂ + CO NH ₂ + NO → N ₂ + H ₂ O CO + NO → N ₂ + CO _{2 The} reaction takes place at approximately 900~1100℃, which is more efficient than spraying chemical agent B1 in the third picture. Under oxygen-deficient conditions, the carbon particles produced by high-temperature cracking in the fuel can react with water vapor generated by the vaporization of water C2, which can also increase combustion efficiency, reduce incomplete combustion particles, and reduce particles in exhaust smoke. Like pollutants, the water gas reaction is shown below. C+ H ₂ O → CO + H ₂ C + H ₂ O → CO ₂ + H ₂ CO + H ₂ O → CO ₂ + H ₂ 2H ₂ + O ₂ → 2H ₂ O On the other hand, due to the evaporation of water C2 , Balance the temperature field during combustion, thereby inhibiting the formation of nitrogen oxides. Through the above-mentioned secondary atomization and water gas reaction, the environmentally friendly emission reduction fuel C1 can achieve the dual effects of reducing air pollution and saving energy. If organic wastewater is used as the water source, the organic substances contained in the organic wastewater can be burned together when the environmentally friendly emission reduction fuel C1 is burned. Not only can the organic wastewater that need to be treated with extra money be recycled and converted into fuel, but also the environmentally friendly emission reduction fuel C1 can be added. The calorific value produced during combustion.

In the sixth figure, you can see the water particle size distribution diagram of the environmentally friendly emission reduction fuel made by the present invention after 3 months of storage. The water source is tap water and no chemicals are added. It can be seen that the average particle size is about 2um~5um. The overall size distribution is approximately between 2um and 8um; it means that the environmentally friendly and emission-reducing fuel has no oil-water separation after 3 months of storage, and the water particle size is still quite small.

The seventh figure is a comparison table between the environmental protection and emission reduction fuel made by the present invention and general heavy oil. The water source used in the environmental protection emission reduction fuel in this comparison table is tap water and no chemicals are added; it can be seen in Table (a) The water content of the environmentally friendly emission reduction fuel sent for testing is 18.5% by volume, and the tested net calorific value is only about 3% less than that of the heavy fuel oil. This means that the environmentally friendly emission reduction fuel requires the same amount of heat generation. The actual fuel quantity is about 84% of general heavy oil ((9771/9440)*(1-0.185)=0.84), which can reduce fuel consumption by 16%. It can be seen that environmentally friendly and emission-reducing fuel can increase combustion efficiency and greatly reduce combustion in exhaust gas. Incomplete carbon particles.

The table (b) in the seventh figure is a comparison table of the emissions of the environmentally friendly emission reduction fuel of the present invention and traditional heavy oil. The environmentally friendly emission reduction fuel in the table is the same as that of Table (a). It can be found that the environmental protection emission reduction fuel produced after combustion Nitrogen oxides are reduced by about 22%. If the aforementioned agents such as alcohols, enzymes and urea are mixed into environmentally friendly emission reduction fuels, the production of nitrogen oxides NO _X can be further reduced.

The present invention can adjust the water content to achieve the highest combustion efficiency according to the different temperature boilers used in various industries. As shown in Figure 8, industries that require high-temperature boilers such as glass fiber manufacturing, glass industry, ceramics industry, cement industry, etc. Metallurgy, mining asphalt plants and power plants can use environmentally friendly fuels with a moisture content of about 15%; the pharmaceutical industry, petrochemical industry, dyeing and finishing industry, printing and dyeing industry, textile industry, dairy industry, chemical industry and The dye industry can use environmentally friendly fuels with a moisture content of about 25%; lower temperature boilers such as food industry, hospitals, hotels, swimming pools, public buildings and general industries can use environmentally friendly fuels with a moisture content of about 35%.
