Description

Method and equipment for enhancing combustion efficiency

The invention relates to a method for enhancing combustion efficiency and a device applying the method, in particular to a method capable of enhancing the combustion efficiency of an existing combustion device, such as a boiler, an engine, and the like, and a device applying the method.

Combustion releases energy. Mankind gains power by learning to control combustion. It has continuously improved the standard of living since the Industrial Revolution. However, with the rise of benefits, the disadvantages also follow. In the living environment, as large as a coal-fired generator and as small as an engine of a steam locomotive, while providing convenient electricity or power, it also increases waste heat and exhaust emissions. Ideally, the only waste gas to burn is water vapor and carbon dioxide, so that it will have the least damage to the environment and human health. However, due to machine aging, fuel composition, combustion environment and other factors, the exhaust gas generated by the aforementioned equipment often contains some incomplete combustion materials, such as hydrocarbons (HC) and carbon monoxide (CO), and toxic exhaust gases, such as nitrogen oxides (NOx) With sulfur oxides (SOx). In particular, these emissions will also entrain some heavy metals or combine with airborne dust to form fine suspended particles that are harmful to the human trachea and lungs (PM2.5 often heard). If these devices burn more efficiently, fewer substances will be produced due to the complete combustion of these substances that harm the human body and the environment.

In addition to environment and health, the burning efficiency of equipment is also related to cost. For example, the heavy oil required for one production line of a rolling mill is estimated to be more than 180 million. If you can This part reduces the cost by 8% to 20%. Calculated in one year, it will save the company from 14.4 million to 36 million. In the era of low profits, this has more than doubled the growth of corporate revenue. Therefore, how to strengthen combustion efficiency has been the focus of research in related industries.

FIG. 1 is a flowchart of a method for enhancing combustion efficiency according to an embodiment of the present invention; FIG. 2 is a schematic diagram of a device for enhancing combustion efficiency according to another embodiment of the present invention; and FIG. 3 is another implementation according to the present invention A schematic diagram of an example of a device for enhancing combustion efficiency.

The present invention will be described more specifically by referring to the following embodiments.

Please refer to FIG. 1, which is a flowchart of a method for enhancing combustion efficiency according to an embodiment of the present invention. Here, the enhanced combustion efficiency is to allow the fuel to burn more completely without compromising the supply of combustion air (such as air compression to increase the oxygen content per unit volume), closer to the purpose of the elements being water and carbon dioxide after combustion. The method first provides a catalytic combustion accelerator (S01). The catalytic combustion accelerator is the core element of this method, and its components and uses are described below.

In general, after countless tests and modification of the ratio, the components of the catalytic combustion accelerator may include: 0.9 to 1.1 parts by weight of titanium dioxide (TiO2); 68 to 72 parts by weight of ethylene glycol; and Water 21 To 25 parts by weight; surfactant to 1.8 to 2.2 parts by weight; and Zeolite 3.6 to 4.4 parts by weight. A better embodiment is 1 part by weight of titanium dioxide, 70 parts by weight of ethylene glycol, 23 parts by weight of water, 2 parts by weight of a surfactant, and 4 parts by weight of zeolite powder. Formulas of other proportions, as long as they fall within the aforementioned range, can achieve the purpose of enhancing combustion efficiency and are claimed by the present invention. In practice, the surfactant can be sodium dodecyl sulfate (Sodium Dodecyl Sulfate).

Because the catalytic combustion accelerator has the above-mentioned components, it can increase the oxygen content when assisting the combustion of fuels (which can be solid, such as coal, liquid, such as heavy oil or gasoline, or even gaseous, such as natural gas) to enhance combustion. effectiveness. Catalytic combustion accelerators increase the oxygen content to enhance combustion efficiency mainly through the following effects.

種光觸媒原子，在燃燒室內經380nm可見光照射後(一般燃燒都會產生380nm的可見光)，電子電洞對(原子)中的電子(帶負電)吸收能量而穿越3.2eV之能隙至導電帶，因電子的光還原(Photo Reduction)作用，使氧變成帶負電之活潑性很高的氧，即活性氧(Activated Oxygen)，留在原地(價電帶)之電洞(帶正電)，因為電洞的光氧化(Photo Oxidation)作用(汽態)，電洞會和二氧化鈦表面上的OH反應(氧化)，生成氧化性很高的OH^-自由基。活潑的OH^-自由基和帶負電之活潑性很高的氧，會把有機物(碳氫化合物)分解，重新降解成為二氧化碳和水。 First, negative oxygen effect. Titanium dioxide is

This kind of photocatalyst atom, after being irradiated with visible light at 380nm in the combustion chamber (commonly, visible light at 380nm is generated), the electron hole (electron) in the (atom) absorbs energy and crosses the energy gap of 3.2eV to the conductive band. The photo-reduction effect of the electrons makes the oxygen become highly reactive oxygen with negative charge, that is, Activated Oxygen, which stays in the hole (positive charge) in the place (valence band) because the electricity Photo Oxidation (Vapor state) of holes, holes will react (oxidize) with OH on the surface of titanium dioxide to generate highly oxidizing OH ^- radicals. Active OH ^- radicals and negatively charged, highly reactive oxygen will decompose organic matter (hydrocarbons) and degrade into carbon dioxide and water again.

Second, oxygen enrichment. The composition of air is mainly a mixture of 78% nitrogen, 21% oxygen, and 1% rare gases and impurities. Under normal natural combustion conditions, the oxygen concentration is 21%. If air with higher oxygen content than the natural state is used as combustion air, it will be oxygen-enriched combustion. It is known from the negative oxygen effect that the highly charged and highly reactive oxygen will be completely combusted with hydrocarbons to degrade into carbon dioxide and water. In addition, the electrode plate effect (the electrolysis potential of water is 1.23V) reduces water (vapor state) to H ⁺ and OH ^- cycle again and again. According to the experiments, it can increase the oxygen content of 2% to 5%, which is the so-called oxygen-rich effect. In addition, with the enrichment of oxygen, the theoretical air requirement is reduced and the flame temperature during combustion can be increased. This is also a factor for enhancing combustion efficiency.

層有2個電子、第二層有5個電子)。但以第二層的軌域數來看，應該要達到8個電子才會穩定，但卻少掉3個電子(即所稱的空軌域)。本發明可 利用所產生的電子，將原先空軌域進行填補，使氮達到穩定的狀態，而不與氧氣結合，進而減少NOx產生的機率。但因本發明尚有富氧的效果，因此除了空軌域的機制之外，在氧氣足夠的前提之下，還可降低進風量，減少過多的氮氣，以增進燃燒效率。 Third, the role of atomic orbital filling. The electronic order of nitrogen is 7, which is explained from a scientific point of view. 1S2S2P should have 4 orbitals and 8 electrons in the second layer, and nitrogen contains 7 electrons (also

Layer has 2 electrons and the second layer has 5 electrons). However, in terms of the number of orbital domains in the second layer, 8 electrons should be stable before 3 electrons are missing (the so-called empty orbital domain). The invention can use the generated electrons to fill the original empty orbital region to make nitrogen reach a stable state without combining with oxygen, thereby reducing the probability of NOx generation. However, because the present invention still has an oxygen-enriched effect, in addition to the mechanism of the empty orbit area, under the premise of sufficient oxygen, the amount of air intake can be reduced and excessive nitrogen can be reduced to improve combustion efficiency.

Fourth, far infrared decomposition. The catalytic combustion accelerator of the present invention also generates far-infrared rays while electrolyzing oxygen, and uses friction characteristics of different expansion coefficients of carbon molecules to generate friction, thereby further coking and slagging in the combustion chamber to gently decompose and participate in combustion, so that Improve combustion efficiency.

From the above description, the function of the catalytic accelerant can be clearly understood. Therefore, in order to optimize the use of the catalytic accelerant, the second step of the method for enhancing combustion efficiency proposed by the present invention is to atomize the catalytic accelerant (S02). There are many ways to atomize, such as oscillating the liquid level of the catalytic accelerant with a high frequency to produce an atomizing effect, atomizing with a conventional atomizing nozzle, or atomizing by heating, which are all feasible methods. The important point is to enable the catalytic combustion promoter to be effectively dispersed in the air after being atomized. Next, the atomized catalytic combustion accelerator is mixed with air to form a mixed mist (S03). Finally, the mixed mist is guided into a combustion chamber for combustion with a fuel, and the combustion temperature of the combustion chamber is not lower than 300 degrees Celsius, and the purpose of maintaining the combustion temperature is not lower than 300 degrees Celsius is to make titanium dioxide in the nanometer Under the structure, the photocatalytic reaction can be performed smoothly.

In addition, the ratio between the dosage of the catalytic accelerant and the amount of the fuel falls within a specific ratio interval, that is, the dosage of the catalytic accelerant used is limited, and too much or too little will not enhance combustion efficiency. From the results of the experiment, it can be known that the specific ratio interval varies depending on the fuel. For example, if the fuel is heavy oil, the specific ratio range is one liter of catalytic combustion aid for 5,040 liters to 6,560 liters of heavy oil; when the fuel is natural gas, the specific ratio range is one liter of catalytic combustion aid for 5,040 degrees to 6,560. Natural gas; if the fuel is coal, the specific ratio range is one liter of catalytic combustion aid for 11.9 to 13.1 metric tons of coal.

The atomizing module 20 is indirectly connected to the catalytic accelerant tank 10 via a catalytic accelerant communication pipe 12. In practice, the two can also be directly connected. The atomizing module 20 can be used to atomize the catalytic combustion accelerator 100 in the catalytic combustion tank 10 and mix with the air to form a mixed mist. The atomizing module 20 may further include two components: a feed control motor 22 and an atomizer 24. The feed amount control motor 22 can control the amount of the catalytic accelerant 100 that is atomized per unit time, that is, to maintain the ratio between the dosage of the catalytic accelerant 100 and the amount of fuel in the previous embodiment falling within a specific ratio interval Inside. The atomizer 24 performs atomization, and moves the atomized catalytic combustion aid 100 to an opening 32a of the transmission gas pipe 32 under the negative pressure in the transmission gas pipe 32 so as to communicate with the air (fine hollow from the transmission gas pipe 32) (Arrow) is mixed to form a mixed mist (cloudy mist shape near the opening 32a).

In this example, the fuel 500 is received by the fuel communication pipe 52, and the flow of the fuel 500 is not limited by gravity or pressure. The combustion space 46 (shown by the dotted frame) is the place where the combustion occurs, and the fuel 500 and the mixed mist 140 are burned here after being initially mixed. when Of course, the so-called burning here may be more explosive in the form of an explosion. The exhaust hole 48 can discharge the exhaust gas 160 after combustion to the combustion chamber 40. In practice, the form of the combustion chamber 40 may be a device such as a boiler, an engine, etc. that needs to operate by burning fuel.

As described in the previous embodiment, the combustion chamber 40 can maintain the combustion temperature not lower than 300 degrees Celsius. The ratio between the amount of the catalytic combustion aid 100 and the amount of the fuel 500 also falls within the specific ratio range described above. The catalytic combustion accelerator 100 includes: 0.9 to 1.1 parts by weight of titanium dioxide; 68 to 72 parts by weight of ethylene glycol; 21 to 25 parts by weight of water; 1.8 to 2.2 parts by weight of a surfactant; and 3.6 to 4.4 parts by weight of a zeolite powder.
