Description

Technical Field

[0001] This invention belongs to the field of mixed air gas production technology, and in particular relates to a gas production device that uses aluminum-plastic oil to produce mixed air gas. Background Technology

[0002] As early as the 1990s, technicians discovered that C5 oil, a byproduct of oil refineries, had a low density (0.62-0.68 g / m³), a low flash point (28°C), and a high calorific value (10560 kcal). Due to the limitations of technology at the time, C5 oil had no practical use, and many refineries and chemical plants could only burn and discharge it using flares. Technicians took advantage of these characteristics to heat up the C5 oil to vaporize it and add a certain amount of air to output it to gas-using equipment. However, because the temperature could not be adjusted after vaporization, its application range was limited. In addition, many enterprises at the time were still using coal as a raw material, which prevented the development of mixed air technology. In 2018, GB / T13611-2018 included mixed air in the category of urban gas, defining it as the fourth generation of urban gas. Mixed air gas then began to develop. In the early years, public awareness of mixed air gas was insufficient, and the price of C5 fuel oil was rising. Furthermore, the purchase of C5 fuel oil was restricted to units with hazardous chemical operation licenses, greatly limiting the user base. In recent years, the government's vigorous crackdown on environmental emissions has led to fewer and fewer companies using coal. When people began to pay attention to mixed air gas, they discovered that the price of C5 fuel oil had approached that of refined oil, significantly reducing the commercial value of mixed air gas using C5 fuel oil as a raw material. After continuous exploration and experimentation, the aluminum-plastic oil gas production project was successfully developed. Aluminum-plastic oil has a high calorific value (10540 kcal) and high density (0.82-0.85 g / cm³). The advantage of high density is its safety, as it is not easily ignited by open flame, and its price is low.

[0003] However, the atomization of aluminum-plastic oil is relatively troublesome. There are currently no examples of using aluminum-plastic oil to prepare mixed air-fuel gas, and it is even more difficult to precisely control the atomization speed and atomization effect. Summary of the Invention

[0004] The purpose of this invention is to provide a gas generating device that uses aluminum-plastic oil to produce mixed air-fuel gas. It draws oil droplets into the tube and onto the ultrasonic atomizer through the Venturi tube principle. The atomization effect is improved by adjusting the oil suction speed by adjusting the airflow. This invention solves the problems of limited existing aluminum-plastic oil atomization cases and uncertain controllability of atomization accuracy.

[0007] The present invention is further configured such that the front end of the oil dripping head is provided with a conical dripping head, and the rear side wall of the oil dripping head is provided with uniform oil seepage holes. The filter holes on the first cylindrical filter cover and the second cylindrical filter cover are respectively the first filter hole and the second filter hole. The diameter of the first filter hole is larger than the diameter of the second filter hole, and the diameter of the second filter hole is larger than the diameter of the oil seepage hole.

[0008] The invention is further configured such that the outer wall of the thin tube section on the venturi tube is provided with external threads, the thin tube section spirally extends from the top of the mounting base plate to the bottom and is fixed at the bottom of the thin tube section with a tightening nut, and four mounting holes are evenly distributed on the side wall of the thin tube section near the top position, the oil dripping head sealing plug is in the mounting hole and the conical dripping head is inserted into the inside of the thin tube section.

[0009] The present invention is further configured such that the ultrasonic atomizer unit includes a plug rod, a mounting support rod, a dripping disc, and ultrasonic atomizers. A high-pressure air inlet is provided in the middle of the plug rod, and four mounting support rods are provided around the top of the plug rod along the high-pressure air inlet. The dripping disc is fixed on the top of the four mounting support rods. Four ultrasonic atomizers are evenly embedded in the annular groove on the upper surface of the dripping disc, and the conical drip tip is located directly above the annular groove.

[0010] The present invention is further configured such that both the atomizing oil outlet pipe and the atomizing oil inlet pipe are fitted with heat-insulating heating sleeves on their outer walls.

[0015] The present invention has the following beneficial effects: 1. This invention uses ultrasonic atomization to atomize aluminum-plastic oil. The oil is drawn into a venturi tube by the pressure difference and dripped onto the vibrating plate of the ultrasonic atomizer, thus atomizing the aluminum-plastic oil. The atomized aluminum-plastic oil rises with the airflow in the venturi tube. Due to the high air pressure in the atomizing tank, the airflow is discharged from the atomizing oil outlet pipe into the atomizing oil inlet pipe and enters the oil storage tank, where it condenses into liquid. However, when the airflow rises in the aluminum-plastic oil, it carries vaporized aluminum-plastic oil, forming a mixed air-fuel mixture of aluminum-plastic oil and gas, effectively achieving the purpose of atomizing aluminum-plastic oil to prepare a mixed air-fuel mixture.

[0016] 2. The amount of airflow introduced into the Venturi tube in this invention determines the pressure difference inside the Venturi tube. The faster the oil droplets are adsorbed by negative pressure, the faster the atomization speed of the atomized oil is controlled by automatically controlling the atomization effect of the ultrasonic atomizer to match the oil droplet speed, thereby achieving the purpose of precisely controlling the atomization of aluminum-plastic oil.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 The present invention is a gas generating device for producing mixed air gas using aluminum-plastic oil, comprising an atomizing canister 1, an atomizing component and an oil storage tank 6; The atomizing can 1 is provided with a detachable can bottom 2 and a first can cover 11. The detachable can bottom 2 is an inverted conical truncated cone shape. The first can cover 11 is provided with an oil inlet pipe 111, an atomizing oil outlet pipe 4 and a booster pipe 112. The oil inlet pipe 111 and the booster pipe 112 are located near the two sides of the first can cover 11. The oil inlet pipe 111 passes through the first can cover 11 and is inserted into the lower half of the atomizing can 1. The atomizing oil outlet pipe 4 is installed in the middle of the first can cover 11 and communicates with the inside of the atomizing can 1. The detachable can bottom 2 is installed at the bottom of the atomizing can 1. The atomizing assembly includes a venturi tube 9, drip heads 90, an ultrasonic atomizer unit, and a mounting plate 8. The mounting plate 8 is spirally mounted on the bottom of the removable canister bottom 2. The venturi tube 9 passes through the mounting plate 8 to the bottom. The upper half of the venturi tube 9 is a thick tube section 92, and the lower half is a thin tube section 91. The ultrasonic atomizer unit is installed inside the thin tube section 91. Four drip heads 90 are embedded in the side wall of the thin tube section 91 near the thick tube section 92. High-pressure gas is filled into the venturi tube 9 from the bottom of the thin tube section 91. The top of the thick tube section 92 is located near the top of the atomizing canister 1. The lower half of the outer wall of the oil storage tank 6 is provided with a heat insulation structure. The bottom of the oil storage tank 6 is provided with an oil drain pipe 62 (for external collection or timely discharge of settled oil). The top of the oil storage tank 6 is equipped with a second tank cover 61. The second tank cover 61 is provided with an atomizing oil inlet pipe 5, an air inlet pipe 611 and a mixed gas mixing pipe. The atomizing oil outlet pipe 4 is connected to the atomizing oil inlet pipe 5. The atomizing oil inlet pipe 5 is provided with a detachable insertion pipe 51 at the bottom of the second tank cover 61. The insertion pipe 51 extends into the oil storage tank 6 near the bottom. The upper half of the oil storage tank 6 is provided with an isolation plate 63 (the isolation plate has evenly distributed air holes, which facilitates the dispersion and flow of gas on the isolation plate, making the carrying of aluminum-plastic oil more efficient).

[0030] Aluminum-plastic composite fuel oil is produced through an aluminum-plastic pyrolysis process, and its main component is a mixture of hydrocarbons resulting from the cracking of plastics. Currently, aluminum-plastic composite fuel oil is primarily used as fuel oil in cement plants, glass factories, ceramic factories, power plants, steel mills, and boiler plants. Alternatively, after decolorization, desulfurization, and cutting treatment, it can be added to ship engines as a power oil.

[0031] However, aluminum-plastic oil cannot be used directly as a fuel mixture for air combustion because its oil particles are uneven. This can easily lead to incomplete combustion or even an explosion. It needs to be atomized and then condensed into new oil. Gas is then blown onto the atomized and condensed oil, causing it to be carried away by the gas and evaporate, thus forming a fuel mixture of aluminum-plastic oil and air.

[0032] When the initial aluminum-plastic oil is added to the atomizing can 1, it submerges the venturi tube 9. As high-pressure gas is blown into the venturi tube 9, the gas pressure increases after entering the coarse tube section 92 from the thin tube section 91. The air pressure inside the atomizing can 1 is not much different from that in the coarse tube section 92, but the air pressure inside the thin tube section 91 is low. Since the thin tube section 91 is located in the lower half of the oil (near the bottom of the can), the oil itself also has oil pressure, which causes the aluminum-plastic oil to be forced into the drip head 90. From the drip head 90, it drips into the thin tube section 91 and onto the vibrating plate in the ultrasonic atomizer unit, thus achieving oil droplet atomization. The atomized oil is blown upwards in the venturi tube 9 with the airflow, and the atomized oil outlet pipe 4 is the air outlet pipe, which carries the atomized oil to the oil storage tank 6 for storage. When atomization is not required, the gas can be blown from the atomizing oil inlet pipe 5 into the oil storage tank 6 by pressurizing the atomizing can 1 (pressurizing pipe 112 pressurizes the atomizing can 1 through a pressurizing pump) to achieve oil evaporation or carry-over. If the air mixing ratio needs to be adjusted, air can be introduced through the air inlet pipe 611 to adjust the air mixing ratio.

[0033] The mounting base plate 8 is provided with a first annular slot 810 and a second annular slot 820 concentrically arranged. A first cylindrical filter cover 81 and a second cylindrical filter cover 82 are respectively inserted into the first annular slot 810 and the second annular slot 82. Filter holes are evenly distributed on the side walls of the first cylindrical filter cover 81 and the second cylindrical filter cover 82. The coarse tube section 92 penetrates the top wall of the first cylindrical filter cover 81 and the second cylindrical filter cover 82.

[0034] The first cylindrical filter hood 81 and the second cylindrical filter hood 82 can filter agglomerated oil, preventing agglomerated oil from clogging the drip head 90 and preventing the drip head 90 from failing to drip oil. The Venturi tube screw connection hole 83 is used to screw on the thin tube section 91 on the Venturi tube 9.

[0035] The oil dripping head 90 has a tapered dripping head 902 at its front end, and uniform oil seepage holes 901 are provided on the rear side wall of the oil dripping head 90. The filter holes on the first cylindrical filter cover 81 and the second cylindrical filter cover 82 are the first filter hole and the second filter hole, respectively. The diameter of the first filter hole is larger than the diameter of the second filter hole, and the diameter of the second filter hole is larger than the diameter of the oil seepage hole 901.

[0036] The aluminum-plastic oil is filtered in stages, which makes oil filtration more convenient. When the oil reaches the inside of the second cylindrical filter cover 82, it is already quite fine. After entering through the oil seepage hole 901, it can drip from the oil drip head 90. The dripping oil particles will be smaller, which is more conducive to atomization.

[0037] The thin tube section 91 on the Venturi tube 9 has external threads on its outer wall. The thin tube section 91 spirals from the top of the mounting base plate 8 to the bottom and is fixed at the bottom of the thin tube section 91 with a tightening nut 912. The thin tube section 91 has four mounting holes 911 evenly distributed on its side wall near the top. The drip head 90 is sealed in the mounting holes 911 and the conical drip head 902 is inserted into the thin tube section 91.

[0038] The thin tube section 91 on the venturi tube 9 is screwed onto the mounting base plate 8 and can be removed for easy maintenance. The removable tank bottom 2 can also be removed for cleaning of the atomizing position. The four drip heads 90 inside the four mounting holes 911 can evenly introduce oil from all four sides, resulting in better oil intake and facilitating the control of oil intake speed through air pressure difference.

[0039] The ultrasonic atomizer unit includes a plug rod 3, mounting support rods 32, a dripping disc 31, and ultrasonic atomizers 311. The plug rod 3 has a high-pressure air inlet 30 in the middle. Four mounting support rods 32 are arranged around the top of the plug rod 3 along the high-pressure air inlet 30. The dripping disc 31 is fixed on the top of the four mounting support rods 32. Four ultrasonic atomizers 311 are evenly embedded in the annular groove on the upper surface of the dripping disc 31. The conical drip tip 902 is located directly above the annular groove.

[0040] The stopper rod 3 can be inserted into the bottom of the thin section 91 of the venturi tube 9 so that the oil dripping disc 31 is pushed onto the oil dripping head 90 so that the oil dripping head 90 is just above the oil dripping disc 31. The oil is drawn in and drips into the annular groove, where it flows onto the ultrasonic atomizer 311 and comes into contact with the vibrating plate, causing ultrasonic vibration atomization.

[0041] The oil-drip disc 31 can also block the airflow from directly blowing the dripping droplets, and the high-pressure airflow has little impact on the droplet's position.

[0042] Both the atomizing oil outlet pipe 4 and the atomizing oil inlet pipe 5 are fitted with heat-insulating and heating jackets on their outer walls.

[0043] To prevent the atomized oil from condensing or sticking to the walls of the atomized oil outlet pipe 4 and the atomized oil inlet pipe 5, the pipes are heated to reduce the amount of oil sticking to the walls.

[0044] The insertion tube 51 is equipped with a one-way valve, which opens downwards.

[0045] When the connection between the connector 51 and the oil storage tank 6 stops, the internal air pressure of the oil storage tank 6 will not drop instantly, which may cause backflow of air pressure. The oil will flow upward along the connector 51. A one-way valve can prevent backflow. Alternatively, unstable air pressure during air blowing can also cause oil backflow. A one-way valve can prevent oil backflow in these cases.

[0046] The insulation structure includes a metal sleeve 60, which has an annular water cavity inside. The top and bottom of the metal sleeve 60 are respectively provided with a water outlet pipe and a water inlet pipe, and the water temperature in the annular water cavity is 35-40℃.

[0047] The annular water cavity of the metal sleeve 60 is filled with water. Hot water is added from the inlet pipe and cold water is discharged from the outlet pipe, so that the metal sleeve 60 maintains a constant temperature and the temperature inside the oil storage tank 6 remains constant.

[0048] The gas-mixing pipeline includes a gas-mixing outlet pipe, a mixing chamber 7, a gas-mixing pipe 72, and an MPG supply pipe 71. The gas-mixing outlet pipe is inserted through the second tank cover 61. The bottom end of the mixing chamber 7 is connected to the top end of the gas-mixing outlet pipe. The top end of the mixing chamber 7 is connected to an L-shaped MPG supply pipe 71. The gas-mixing pipe 72 is connected to the middle position of the mixing chamber 7.

[0049] A certain amount of more combustible gas (such as natural gas, propane, etc.) is discharged from the mixing pipe 72 into the mixing chamber 7 to mix with the aluminum-plastic oil, which facilitates combustion. The mixed fuel gas is collected from the MPG supply pipe 71.

[0050] Both the first tank cover 11 and the second tank cover 61 are equipped with ultrasonic level gauges on their lower surfaces.

[0051] The ultrasonic level gauge measures the liquid level in the first tank cover 11 and the second tank cover 61 in real time. When the oil level in the atomizing tank 1 is low, the initial aluminum-plastic oil is replenished in time. When the amount of aluminum-plastic oil in the oil storage tank is low, it is replenished in time through atomization.
