Description

Technical Field

[0001] The invention relates to the technical field of emergency substitute fuel blending equipment, and in particular to a skid-mounted emergency substitute fuel online pipeline blending device and method. Background Art

[0002] Gasoline and diesel, as two common liquid fuels, are widely used in the power units of cars, motorcycles, small agricultural machinery, trucks, tanks and ships, and play an important role in all walks of life. Emergency alternative fuel refers to a technology that makes full use of local fuel varieties or nearby local resources to provide emergency support for equipment oil by using alternative fuels or blended fuels when the fuel cannot meet the fuel variety and quality grade required by the equipment in natural disasters such as earthquakes, typhoons, rainstorms, lightning, hail or emergency situations such as war. Emergency alternative fuel refers to an emergency practice of mixing one or more other fuels with designated oil to increase the designated oil reserves when there is a shortage of designated oil reserves in war or remote areas.

[0003] For example, in war or remote areas, the designated oil for a certain type of vehicle is a certain type of diesel, but the fuel reserves only contain a certain amount of gasoline, diesel and kerosene. The diesel reserves alone cannot support the vehicle's maneuvering to the expected refueling station. Therefore, a certain proportion of gasoline and kerosene can be added to diesel. After mixing, the amount of diesel reserves that can be adapted to the vehicle can be greatly increased. Although the mixed alternative fuel will experience varying degrees of performance degradation such as reduced output power when used, it can enable the vehicle to safely drive to the refueling station in an emergency state without causing irreversible damage to important components such as the vehicle's engine.

[0004] Static mixer is a kind of high-efficiency mixing equipment without moving parts. Through the internal parts of the mixing unit fixed in the tube, two or more streams of fluid are cut, sheared, rotated and remixed to achieve the purpose of good dispersion and full mixing between the fluids. Compared with traditional mixing equipment, static mixer has the advantages of simple process, compact structure, low energy consumption, low investment, high operational flexibility, no maintenance, and good mixing performance. Static mixer can replace traditional related equipment in any process involving liquid-liquid, liquid-gas, liquid-solid, gas-gas mixing, emulsification, neutralization, absorption, extraction, reaction and enhanced heat transfer.

[0005] The problem with existing static mixers is that the mixing efficiency is low when mixing in an emergency, which makes it difficult for the mixed substitute fuel to meet the uniformity standard. When vehicles use this emergency substitute oil with poor mixing uniformity, the oil quality will not meet the emergency substitute oil standard for a short period of time, causing irreversible damage to the engine or even causing it to break down. Summary of the invention

[0019] Optionally, the fixed end of the deceleration plate is located lower than the other end.

[0020] Through the above technical solution, the fixed end of the slow flow plate is located lower than the other end, so that when the mixed fuel passes through the fuel downward channel and falls onto the slow flow plate, it can flow out slowly due to the accumulation effect, which can increase the uniformity of fuel mixing.

[0026] Through the above technical solution, the arc-shaped injection surface can make the fuel sprayed from the corresponding upper nozzle and lower nozzle contact more evenly, reduce scattering to the outside, and cause uneven mixing of a small amount of fuel.

[0076] Example 1: Online pipeline blending of automotive gasoline and automotive diesel as emergency alternative fuel

[0077] 1. Emergency alternative plan for blending gasoline with diesel

[0078] Emergency alternative solution for blending automotive diesel into automotive gasoline:

[0079] Scheme 1: 80% No. 89 gasoline (VIA) (GB17930-2016) + 20% No. 0 diesel (VI) (GB19147-2016)

[0080] Scheme 2: 70% No. 89 gasoline (VIA) (GB17930-2016) + 30% No. 0 diesel (VI) (GB19147-2016)

[0081] 2. Online pipeline blending operation process of automotive gasoline mixed with automotive diesel emergency alternative fuel

[0082] A certain amount of No. 89 gasoline pipeline is connected to the main fuel feed pipe 31, and a certain proportion of No. 0 diesel is connected to the auxiliary fuel feed pipe 32. No. 89 gasoline enters from the main fuel feed pipe 31, passes through the main fuel buffer tank 211, and flows into the main fuel pressure pump 213. The main fuel pressure pump 213 pressurizes the main fuel to 0.2Mpa;

[0083] No. 0 diesel fuel enters from the auxiliary material feed pipe 32, passes through the auxiliary material buffer tank 212 and flows into the auxiliary material pressure pump 214, and the auxiliary material pressure pump 214 pressurizes the auxiliary material to 0.1 MPa;

[0084] The number of the lower nozzles 44 and the upper nozzles 43 is three, and the lower nozzles 44 and the upper nozzles 43 are numbered from one side of the main fuel inlet pipe channel to the other side. The lower nozzles 44 are numbered B1, B2, B3, and the upper nozzles 43 are numbered U1, U2, U3;

[0085] The output pressure of the main fuel booster pump 213 is 0.2 MPa, and the output pressure of the auxiliary fuel booster pump 214 is 0.1 MPa. The mixing controller 22 controls the pressure in the main fuel distribution pipe 46 connected to the Nth lower nozzle 44 to PP by controlling the hydraulic solenoid valve 47. N , The pressure in the main fuel distribution pipe 46 connected to the Nth upper nozzle 43 is controlled to PUP N , The main fuel sprayed from the lower nozzle 44 and the auxiliary material sprayed from the upper nozzle 43 are mixed in a high-pressure spray counter-attack manner, and the mixed fuel is transported downward through the mixed oil downward channel; the mixed fuel falls on the side of the fixed end of the slow flow plate 217, and after forming an accumulation, it slowly falls through the fuel downward channel to the bottom of the mixer shell 215, and can be released from the oil outlet device 10.

[0086] The whole mixing process was completed in 9 minutes and 30 seconds. After testing, the mixing degree of the emergency substitute oil was 1.1%. The blended samples were recorded as: Sample 1 or Sample 2.

[0087] 3. Analysis and testing of key performance indicators of emergency substitute fuels for automotive gasoline mixed with automotive diesel

[0088] The distillation range, freezing point, colloid, saturated vapor pressure, calorific value and octane number in the product specification of automotive gasoline (VIA) (GB17930-2016) were used as key performance indicators for analysis and testing. The results are shown in Table 1.

[0089] Table 1 Key physical and chemical properties test data of emergency substitute fuel blended with diesel for motor vehicle gasoline

[0090]

[0091]

[0092] As shown in Table 1, compared with No. 89 gasoline, the physical and chemical properties of the two samples have changed significantly:

[0093] (1) The distillation range has been improved to varying degrees and has exceeded the technical requirements for gasoline used in my country. Test data show that the initial distillation point and 10% evaporation point temperatures have not changed much and are both close to the standards; the 50% and 90% evaporation point temperatures and the final distillation point are far from the standards.

[0094] (2) The calorific value increases with the increase of the blending ratio, because the blended raw materials contain more heavy components than the basic fuel. Under the premise of complete combustion, a higher calorific value is beneficial to improving the engine power performance.

[0095] (3) Saturated vapor pressure is a test item that characterizes the vaporization ability of fuel. Too high a value is likely to cause vapor blockage, while too low a value is not conducive to the evaporation of fuel and thus affects the combustion efficiency. From the test data, it can be seen that the saturated vapor pressure test data of the two samples both showed a downward trend.

[0096] (4) As the proportion of automotive diesel in automotive gasoline increases, its octane number tends to gradually decrease, which is lower than the required value (≥89) in the automotive gasoline product specification (GB17930-2016).

[0097] 4. Practical application test of emergency substitute fuel of blending automotive gasoline with automotive diesel

[0098] In order to evaluate the comprehensive performance of emergency substitute fuel for automotive gasoline under actual conditions, sample 2 (70% No. 89 automotive gasoline + 30% No. 0 automotive diesel) was selected to carry out driving test on a Santana car (engine: 4-cylinder electronic injection; compression ratio: 9.5; odometer reading: 180,000 kilometers; vehicle condition: good).

[0099] (1) Vehicle cold start

[0100] At temperatures between 10℃ and 18℃, the cold start can be successfully completed within 2-3 times. The throttle needs to be stepped on at the beginning of the start, and normal idling can be achieved after about 1-2 minutes.

[0101] (2) Mountain road climbing test

[0102] The test section is the G319 Shapingba section in Chongqing, from the Banana Garden Bus Station to the Baiguoshu Bus Station. The entire journey is about 14 kilometers and the driving time is about 40 minutes. During the test, except for a slight reduction in vehicle power, there were no other obvious abnormalities.

[0103] (3) Pavement test

[0107] Emergency alternative solution for blending automotive diesel with automotive gasoline:

[0108] Scheme 1: 80% No. 0 diesel (VI) (GB19147-2016) + 20% No. 89 gasoline (VIA) (GB17930-2016)

[0109] Scheme 2: 60% No. 0 diesel (VI) (GB19147-2016) + 40% No. 89 gasoline (VIA) (GB17930-2016)

[0110] 2. Operation process of online pipeline blending of automotive diesel and automotive gasoline as emergency substitute fuel

[0111] A certain proportion of No. 0 diesel fuel is connected to the main fuel feed pipe 31, and a certain proportion of No. 89 gasoline fuel is connected to the auxiliary fuel feed pipe 32. No. 0 diesel fuel enters the main fuel feed pipe 31, passes through the main fuel buffer tank 211, and flows into the main fuel booster pump 213. The main fuel booster pump 213 boosts the main fuel to 0.2Mpa.

[0112] No. 89 gasoline enters from the auxiliary material feed pipe 32, passes through the auxiliary material buffer tank 212 and flows into the auxiliary material pressure pump 214, and the auxiliary material pressure pump 214 pressurizes the auxiliary material to 0.1 MPa;

[0113] The number of the lower nozzles 44 and the upper nozzles 43 is three, and the lower nozzles 44 and the upper nozzles 43 are numbered from one side of the main fuel inlet pipe channel to the other side. The lower nozzles 44 are numbered B1, B2, B3, and the upper nozzles 43 are numbered U1, U2, U3;

[0114] The output pressure of the main fuel booster pump 213 is 0.2 MPa, and the output pressure of the auxiliary fuel booster pump 214 is 0.1 MPa. The mixing controller 22 controls the pressure in the main fuel distribution pipe 46 connected to the Nth lower nozzle 44 to PP by controlling the hydraulic solenoid valve 47. N , The pressure in the main fuel distribution pipe 46 connected to the Nth upper nozzle 43 is controlled to PUP N , The main fuel sprayed from the lower nozzle 44 and the auxiliary material sprayed from the upper nozzle 43 are mixed in a high-pressure spray counter-attack manner, and the mixed fuel is transported downward through the mixed oil downward channel; the mixed fuel falls on the side of the fixed end of the slow flow plate 217, and after forming an accumulation, it slowly falls through the fuel downward channel to the bottom of the mixer shell 215, and can be released from the oil outlet device 10.

[0115] The entire mixing process was completed in 9 minutes and 30 seconds. After testing, the mixing degree of the emergency substitute oil was 1.1%. The blended samples were recorded as: Sample 1 or Sample 2.

[0116] 3. Analysis and testing of key performance indicators of emergency substitute fuels for automotive diesel mixed with automotive gasoline

[0117] The distillation range, 40°C kinematic viscosity, pour point, cetane number and HFRR wear spot diameter in the automotive diesel (VI) product specification (GB19147-2016) were used as key performance indicators for analysis and testing. The results are shown in Table 2.

[0118] Table 2 Key physical and chemical properties test data of emergency substitute fuel of diesel blended with gasoline

[0119]

[0120] As shown in Table 2, after No. 0 diesel is blended with No. 89 gasoline, the evaporation point temperature of the oil sample decreases with the increase of the blending ratio of gasoline, the initial distillation point is close to gasoline, and the final distillation point is close to diesel; the 40℃ kinematic viscosity of the oil sample decreases with the increase of the blending ratio, which may cause wear and leakage of the high-pressure oil pump and reduce the atomization effect; compared with No. 0 diesel, the condensation point of the oil sample is significantly reduced, which is beneficial to improve the low-temperature flow performance of the fuel. After blending gasoline in diesel, its cetane number decreases to varying degrees. After blending 20% ​​of gasoline, the cetane number of the oil sample decreases by 10.4 units, and after blending 40% of gasoline, the cetane number of the oil sample decreases by 17.3 units, both of which are less than the product specification requirement of No. 0 diesel ≮51. After No. 0 diesel is blended with No. 89 gasoline, the HFRR wear spot diameter increases with the increase of the blending ratio, reducing the lubrication performance of the oil sample.

[0121] 4. Practical application test of emergency substitute fuel of diesel blended with gasoline

[0122] In order to evaluate the comprehensive performance of diesel-blended gasoline emergency substitute fuel under actual conditions, sample 2 (60% No. 0 diesel + 40% No. 89 gasoline) was selected to carry out driving test on a Dongfeng truck (odometer reading: 150,000 kilometers; vehicle condition: general).

The main fuel pressure pump 213 pressurizes the main fuel to 0.2Mpa.

[0137] Soybean oil (commercially available) enters from the auxiliary material feed pipe 32, passes through the auxiliary material buffer tank 212, and flows into the auxiliary material pressure pump 214, and the auxiliary material pressure pump 214 pressurizes the auxiliary material to 0.1Mpa;

[0138] The number of the lower nozzles 44 and the upper nozzles 43 is three, and the lower nozzles 44 and the upper nozzles 43 are numbered from one side of the main fuel inlet pipe channel to the other side. The lower nozzles 44 are numbered B1, B2, B3, and the upper nozzles 43 are numbered U1, U2, U3;

[0139] The output pressure of the main fuel booster pump 213 is 0.2 MPa, and the output pressure of the auxiliary fuel booster pump 214 is 0.1 MPa. The mixing controller 22 controls the pressure in the main fuel distribution pipe 46 connected to the Nth lower nozzle 44 to PP by controlling the hydraulic solenoid valve 47. N , The pressure in the main fuel distribution pipe 46 connected to the Nth upper nozzle 43 is controlled to PUP N , The main fuel sprayed from the lower nozzle 44 and the auxiliary material sprayed from the upper nozzle 43 are mixed in a high-pressure spray counter-attack manner, and the mixed fuel is transported downward through the mixed oil downward channel; the mixed fuel falls on the side of the fixed end of the slow flow plate 217, and after forming an accumulation, it slowly falls through the fuel downward channel to the bottom of the mixer shell 215, and can be released from the oil outlet device 10.

[0140] The entire mixing process was completed in 9 minutes and 30 seconds. After testing, the mixing degree of the emergency substitute oil was 1.1%. The blended samples were recorded as: Sample 1, Sample 2 or Sample 3.

[0141] 3. Analysis and testing of key performance indicators of emergency alternative fuels blended with soybean oil for automobile diesel

[0142] The distillation range, 40°C kinematic viscosity, pour point, flash point, cetane number and HFRR wear spot diameter in the automotive diesel product specification (GB19147-2016) were used as key performance indicators for analysis and testing. The results are shown in Table 3.

[0143] Table 3 Key physical and chemical properties test data of emergency substitute fuel blended with soybean oil for automobile diesel

[0144]

[0145]

[0146] As shown in Table 3, the greater the proportion of soybean oil blended with No. 0 diesel, the higher the evaporation point temperature of the oil sample. When the blending ratio is 30%, 50%, and 80%, the distillation range index of the oil sample far exceeds that of No. 0 diesel, which may lead to increased carbon deposits in the engine combustion chamber. The kinematic viscosity of the oil sample increases with the increase of the soybean oil blending ratio. The kinematic viscosity of pure soybean oil is 31.22 mm 2 / s, far exceeding the index of No. 0 diesel. After blending with soybean oil, the pour point of the oil sample increases, which is not conducive to low-temperature pumping of the oil sample. After blending different proportions of soybean oil into No. 0 diesel, the cetane number of the oil sample is significantly improved. After blending soybean oil into No. 0 diesel, the HFRR wear spot diameter decreases with the increase of the blending ratio, improving the lubrication performance of the oil sample.
