Description

Technical Field

[0001] The present invention relates to the technical field of raw coal liquefaction secondary clean energy and energy-saving and emission-reduction clean thermal combustion, and in particular to a raw coal alcohol liquefaction and clean thermal combustion equipment and method based on RSG engineering technology effects. Background Art

[0002] China is rich in coal, poor in oil, and short of natural gas. Its coal reserves rank second in the world, its total consumption accounts for 50%, and its energy consumption structure accounts for 62%. As of 2012, my country's external dependence on oil reached 70% and natural gas reached 45%. The lack of clean energy has become a hidden danger to my country's energy security. Problems with the use of "coal liquefaction fuel" as a secondary energy source in the thermal combustion of small and medium-sized industrial boilers and kilns in my country's water-coal slurry projects: ① Physical methods have not solved the problem of "sulfur and silicate" fuel pollution in coal slurry; ② Traditional combustion technology refers only to thermal combustion and still requires a large flue gas treatment system to compensate for the technical defects of water-coal slurry components; ③ The operation of dedicated combustion and heating devices is environmentally friendly and cannot meet the basic requirements of flue gas emission indicators in my country's key pollution control areas: "dust 10mmg / Nm3, SO2 20mmg / Nm3, NOX 50mmg / Nm3".

[0003] GB16663-1996 "Alcohol-based liquid fuel" is designed to blend industrial methanol materials into secondary clean energy. The pilot results in thermal industrial boilers and kilns and civilian catering stoves have made positive contributions to my country's replacement of diesel and gasoline and elimination of raw coal, water-coal slurry, and biomass high-pollution fuels, and have reached the level of engineering application technology; however, if traditional alternative engineering applications are still adopted, the common problems of low thermal energy efficiency and high system operating costs will continue, and the carbon steel series metals of the heating device will be corroded, causing safety hazards to the pressure equipment. The production cost of pure industrial-grade methanol chemical materials is high, and the price is affected by the chemical market. The price fluctuation is large, so there are still great limitations in the application of thermal combustion. Although my country currently has many methods of adding a variety of heat enhancers to solve the problem of low calorific value of alcohol-based fuels: adding waste gas, diesel, coal, engine oil, tar, tire oil, kitchen waste oil, etc. to alcohol-based fuels to increase calorific value, and adding nitric acid, ferrocene, potassium permanganate, etc. to alcohol-based fuels to increase chemical reaction speed in order to solve the problem of corrosiveness of flue gas condensate, it will inevitably lead to excessive emissions of SO2, NOX, and dust or lose the economy of clean fuels. Therefore, they are unable to undertake the heavy task of industrializing clean thermal combustion of secondary clean energy from raw coal liquefaction in the industrial field.

[0004] To this end, it is very necessary to develop a secondary clean energy source from coal that is suitable for my country's national conditions, has abundant local resources, is inexpensive and of good quality, and to timely develop advanced clean combustion process technologies for safe, energy-saving, efficient and environmentally friendly systems. "RSG Engineering" is the abbreviation of "years of practice precipitation technology" for the application technology of "alcohol fuel" clean thermal combustion system for coal liquefaction in my country. Its ideal goal is to develop "standard clean fuels, special combustion equipment, and enhanced combustion processes" for the clean treatment of ordinary raw coal, and to achieve "safe, environmentally friendly, efficient, and economical" load-added reduction of thermal combustion pollution from coal resources through the benign superposition of multidisciplinary technologies; its technical purpose is to make up for part of the clean energy needed for the rapid development of my country's national economy and to accelerate the scientificization of systematic engineering technology for ecological environmental restoration; RSG engineering technology has been widely practiced and applied in thermal combustion fields such as small and medium-sized industrial boilers and kilns, mining area heating, etc. in my country, aiming to create a scientific and advanced system engineering technology system for the clean application of my country's coal resources.

[0044] The operation process of the above-mentioned raw coal alcohol liquefaction process and thermal clean combustion method based on the RSG engineering technology effect is as follows.

[0045] Standard alcohol fuel R unit (1) operates on solid organic matter liquefied alcohol liquid fuel.

[0046] See Figure 1As shown, the preferred channels for head-end resources should be open-pit coal mines, raw coal from pit-mouth mining areas, and organic matter from agricultural reclamation areas, which are classified and input into the organic resource library (4), and are measured and transported by the solid material conveying mechanism into the material preparation device (6) for routine preparation; the materials that meet the process requirements are then input into the material gasification device (7) by the solid material conveying mechanism for pyrolysis and gasification; CO2 + H2O carbon dioxide and water vapor from the heat recovery device (9), low-temperature methanol washing system (11), methanol synthesis gas sulfur recovery device (12), and exhaust gas combustion device (16) are fed into the material gasification device (7) as part of the gasifying agent to undergo pyrolysis and gasification reaction with the hot materials to produce a crude mixed gas.

[0047] The O2 oxygen produced by the air separation unit (5) is introduced into the material gasification unit (7) by the gas material conveying mechanism, and is used as a part of the gasifying agent to carry out a pyrolysis and gasification reaction with the hot material fed into the material gasification unit (7). The silicate mixed solid material remaining after the pyrolysis is conveyed into the slag disposal system (10) by the solid material conveying mechanism to produce light building material products for sale in the social market, thereby achieving the goal of eliminating the secondary pollution of the slag in the production process and the comprehensive utilization of waste; the first goal of this chemical reaction section is to remove silicate substances so that the flue gas dust emission indicators of the downstream clean fuel products in the thermal combustion meet the environmental protection requirements.

[0048] The crude mixed gas from the material gasification device (7) is subjected to a CO+H2O ⇋CO2+H2 process conversion by the crude synthesis gas CO conversion device (8) to achieve a balance of process parameters of the crude synthesis gas; the crude synthesis gas is passed through a heat recovery device (9) to replace part of the heat energy, and the heat work is used to generate electricity and provide the heat energy required for material preparation, and part of the water vapor is used as the main gasification agent for CO2+H2O+C pyrolysis reforming; the crude synthesis gas is then removed by a low-temperature methanol washing system (11) to remove CO2, H2S and organic sulfur impurities in the conversion gas, and at the same time remove the saturated water brought into the conversion gas. The low-temperature methanol washing system (11) is provided with a set of one-way output pipes connected to the methanol synthesis gas sulfur recovery device (12), and the H2S gas is transported to recover sulfur by burning the H2S gas by a diversion method, and the qualified primary synthesis gas is input into the compressed synthesis gas buffer device (13); when the heat recovery device (9), the low-temperature methanol washing system (11), and the methanol synthesis gas sulfur recovery device (12) are in operation, the excess CO2 and H2O gases are sent to the material preparation device (6), and the material gasification device performs CO2+H2O+C thermal decomposition and reforming treatment; the first goal of the chemical reaction section is to remove S organic sulfur substances, so that the SO2 emission index of the flue gas of the thermal combustion of the downstream clean fuel product meets the environmental protection requirements, thereby reducing the raw material cost in the production process link and improving the cleanliness of the fuel production link.

[0049] See Figure 1 、 Figure 2As shown, the primary synthesis gas from the compressed synthesis gas buffer device (13) is introduced into the alcohol fuel synthesis device (14) through the primary synthesis gas inlet (29) to react with the "temperature-resistant alcohol family" catalyst loaded in the primary synthesis gas catalytic chamber (30), and the synthesized alcohol family compounds are collected in the mixed alcohol stabilization chamber (31). The synthesis gas that escapes after the primary catalysis is forced to circulate by the synthesis gas circulation device (15) by connecting the circulating synthesis gas outlet (35) of the alcohol fuel synthesis device (14) and the circulating synthesis gas inlet (33). The circulating synthesis gas reacts with the "sulfur-resistant alcohol family" catalyst loaded in the circulating synthesis gas catalytic chamber (34), and the synthesized alcohol family compounds are collected in the mixed alcohol stabilization chamber (31) to increase the synthesis rate. The first goal of this chemical reaction section is to increase the synthesis rate of alcohol family materials, increase production capacity, and reduce production costs. The above-mentioned routine route of liquefying solid organic matter into alcohol family liquid fuel is one of the process technology routes with a typical clean thermal combustion RSG engineering technology that can achieve a benign superposition effect.

[0050] The alcohol materials in the mixed alcohol stabilization bin (31) are transported from the alcohol fuel outlet (32) through a pipeline to the buffer storage tank in the production area or the alcohol fuel storage depot (17) of the dedicated combustion equipment S unit (2); those transported over long distances are then transported by pipeline and tank train or tank truck and connected to the fuel inlet of the alcohol fuel storage depot (17) of the dedicated combustion equipment S unit (2), completing the transportation of the alcohol fuel from the production area to the use area.

[0051] Special combustion equipment S unit (2) Special alcohol liquid fuel combustion equipment operation.

[0052] See Figure 1 、 Figure 3 As shown, the alcohol fuel storage depot (17), the alcohol fuel distribution depot (18) and the alcohol fuel user reserve depot (19) are connected by tank trucks and transported to the terminal user's reserve depot. The alcohol fuel is stored in the alcohol fuel user reserve depot (19) for standby use in accordance with relevant requirements; the alcohol fuel is transported to the furnace by a dedicated transport mechanism and connected to the alcohol fuel dedicated combustion device (20) to ensure the supply of alcohol fuel in front of the furnace.

[0053] According to the type of the heating device (25) and the requirements of the combustion process technical parameters, the operating procedures and related parameters of the alcohol fuel special program controller (21) are set to ensure the stability of the operation of the special equipment.

[0054] According to the type of the heating device (25) and the combustion process, specific parameters of the flame safety inspection of the alcohol fuel dedicated combustion device (20) during operation are set, such as setting the flame root safety extension distance Xmm and the flame intensity quantum beam safety self-locking value X beam of the alcohol fuel dedicated monitoring instrument (22) to ensure the safety of the dedicated equipment operation.

[0055] According to the type of the heating device (25) and the output required by the load of the alcohol fuel dedicated combustion device (20), the specific parameters of the alcohol fuel dedicated combustion device (20) in terms of fuel atomization are set, such as the output pressure value kgf / cm2 and the output flow value L / h of the alcohol fuel dedicated fuel pump (23), to ensure the uniformity and stability of the atomization of the dedicated equipment during operation.

[0056] According to the type of the heating device (25) and the requirements of the load output and flame shape of the alcohol fuel dedicated combustion device (20), the specific parameters of the alcohol fuel dedicated combustion device (20) in terms of combustion-supporting air distribution are set, such as the wind speed m / s and the total mixed flow rate Nm3 / h of the alcohol fuel dedicated air distributor (24), to ensure that the premixed fuel flow is coupled with the heating device to produce the set enhanced combustion. The routine setting of the above-mentioned dedicated alcohol liquid fuel combustion equipment is a typical combustion method that can achieve a benign superposition effect of clean thermal combustion RSG engineering technology.

[0057] The alcohol fuel-specific combustion device (20) is allowed to start, and the alcohol fuel-specific fuel pump (23) loads potential energy for the alcohol fuel medium and sprays it out from the atomizer, and pre-mixes it with the mixed combustion agent added by the alcohol fuel-specific air distributor (24) to form a fuel flow. The fuel flow is ignited by the ignition, and under the connection between the output end of the alcohol fuel-specific air distributor (24) and the heat inlet of the alcohol fuel-specific heating device (25), a flame shape is formed according to the set parameter values, and it burns safely, stably and continuously, generating a chemical energy heat source for the end user.

[0058] Enhanced combustion process G unit (3) Alcohol liquid fuel enhanced combustion operation.

[0059] See Figure 1 、 Figure 3 The enhanced combustion process G unit (3) includes support for various enhanced combustion parameters of the alcohol fuel-specific combustion device (20) and is connected to various inputs of the alcohol fuel-specific heating device (25), forming an enhanced combustion process structure with a benign superposition effect of clean thermal combustion RSG engineering technology; one end of the heating device combustion chamber (36) of the alcohol fuel-specific heating device (25) is connected to the alcohol fuel-specific air distributor (24) of the alcohol fuel-specific combustion device (20), and receives the alcohol fuel-specific air distributor (24) from the dedicated combustion equipment S unit (2) to support the combustion flame into the enhanced combustion chamber (37) for safe, stable and continuous heat release.

[0060] In terms of the enhanced combustion process of the alcohol fuel-specific heating device (25), the infrared radiation armor (38) provided in the body constitutes an enhanced combustion chamber (37) to form a fuel heat-gathering combustion space. The combustion flame enters the enhanced combustion chamber (37) and releases heat stably and continuously. When the heat storage energy level of the armor body reaches a transition, it will generate infrared radiation to transfer heat energy to the heating device combustion chamber (36), thereby releasing heat to the heating device and forming enhanced combustion of the premixed fuel, forming a typical RSG high-temperature oxygen-poor excitation oxygen-rich gain effect enhanced combustion structure, releasing heat energy to the water medium in the heating device, and the water vapor generated by the water medium is used for downstream production.

[0061] The flue gas that has undergone primary enhanced combustion in the enhanced combustion chamber (37) all enters the combustion chamber (36) of the heating device for flue gas convection heat exchange, and a portion of the flue gas re-enters the reforming channel (39) for secondary enhanced combustion and convection heat release to the alcohol fuel-specific heating device (25) before serving as the external re-entry flue gas medium.

[0062] Part of the flue gas from the flue gas re-entry reforming channel (39) is transported to the alcohol fuel dedicated combustion device (20) through the reforming flue gas delivery pipe (41), and the pre-mixed fuel flow is coupled to promote the radiation of thermal energy in the infrared band, stimulate the thermal ionization of the fuel particles in the oxygen-rich secondary enhanced combustion, and achieve high-speed combustion in the plasma state to form an ion sheath, thereby creating high-temperature physical conditions for flue gas reforming.

[0063] Part of the flue gas from the flue gas re-entry reforming channel (39) enters the enhanced combustion chamber (37) through the internal re-entry reforming channel (40) provided on the peripheral wall of the front end of the infrared radiation armor (38) to mix with the ion sheath to achieve internal re-entry reforming. The flue gas is introduced into the free state by the high-temperature sheath to sub-disintegrate the NOX molecules and perform N cycles of enhanced combustion, so that some of the oxygen molecules therein participate in the combustion of C, CO, and H2 in a free state with higher activity. When the oxygen covalent bond of N2O3 is sub-broken, it is sub-bound by other molecules or atoms and competitively reacts to become new substances. For example, C atoms are re-combined to become CO2 and N2O, thereby achieving the suppression of NOX and partial reforming.

[0064] Part of the flue gas from the flue gas re-entering reforming channel (39) is transported by the reforming flue gas delivery pipe (41) to the alcohol fuel dedicated combustion device (20), and the premixed fuel flow is coordinated to promote high-temperature excitation of oxygen-poor free oxygen-rich enhanced combustion. The recycled flue gas participates in the premixing of the fuel flow, and when the low α value of 1.01 is reached in the enhanced combustion chamber (37), oxygen-poor and efficient enhanced combustion can still be achieved, thereby achieving the goal of maximizing the reduction of combustion aid consumption, reducing flue gas emissions and suppressing NOX synthesis.

[0065] All the flue gases from the combustion chamber (36) of the heating device are supported by the honeycomb air condensation bundle tubes provided in the special flue gas condensation device (28) for heat exchange between the flue gas and the air, so as to realize the centralized discharge of the flue gas condensate, thereby achieving the purpose of reducing white smoke plume, preventing equipment corrosion and further improving the energy efficiency of the system. The tail end of the special flue gas condensation device (28) is connected to the chimney of the alcohol fuel special heating device (25) or is directly emptied. The initial concentration of the discharged flue gas can reach the ultra-low emission indicators of dust ≤10mg / Nm3, SO2 ≤20mg / Nm3, and NOX ≤30mg, which is completely superior to the core requirements of extreme protection of thermal flame combustion around the world.

[0066] It should be understood that the implementation of the embodiment is merely an exemplary implementation adopted to illustrate the process equipment structure and the principle of enhanced combustion technology of the present invention, and therefore the present invention is not limited thereto.

[0067] For example, a standard alcohol fuel R unit (1) is a solid organic matter liquefied alcohol liquid fuel, and the raw materials for gasification can also be biomass including agricultural and forestry organic waste, urban life organic waste, petroleum coke powder, coal gangue, oil shale, etc.

[0068] Alcohol fuel products can also be used to synthesize high-carbon alcohol fuel products; they can also be blended into clean fuels for volumetric pulse power combustion; they can also be directly used in industries such as stoves in folk catering.

[0069] Therefore, we should understand that for ordinary technicians in this field, various modifications and improvements can be made without departing from the spirit and essential principles of the present invention. However, these modifications and improvements should be regarded as within the scope of protection of the present invention.
