Description

Device suitable for microwave separation oil rock
Technical Field
The invention provides a device suitable for microwave oil-rock separation, which creates a safe and effective microwave treatment environment and avoids the conditions of microwave ignition and thermal runaway.
Background
The global oil shale resource is very rich, and the amount of the resources stored in the oil shale is about 10 trillion tons according to incomplete statistics and is 40 percent more than that of coal resources. The oil shale is distributed intensively and has great potential and favorable conditions as a succeed energy source. The united states is the world with the most abundant resources of oil shale worldwide, and the reserves of 4100 million tons account for about 70% or more of the worldwide reserves. According to the resource quantity, 476 hundred million tons in China are only second to the United states and are located in the second world, and 400 hundred million tons in Russia are located in the third world. Although oil shale resources are abundant, only north america worldwide has achieved large-scale commercial development of oil shale, and China is still in the early development stage of oil shale.
The method for extracting shale oil from oil shale widely used in China is a smoothing furnace which is started to be used in the second war period and a rotary kiln. The smoothie furnace is used for heating the oil shale to 500 ℃ by utilizing high-temperature air to obtain oil in the oil shale. The smooth furnace has two defects, namely, a small oil shale blocks an oil-gas channel of the smooth furnace, and oil in the small oil shale cannot be extracted; and the low oil gas recovery rate causes high oil refining cost and large equipment maintenance cost. Due to the brittleness of the oil shale, the oil shale is very easy to break into small blocks during the mining process. These small pieces of oil shale cannot be refined, wasting a lot of resources. The rotary kiln is a new device introduced from abroad, and can rotate to drive the oil shale in the kiln to turn over so as to timely recover oil gas into a pipeline without being blocked by small oil shale. However, after actual use, the rotary kiln is found to be incapable of claiming 90% of oil recovery rate, but about 65% of oil recovery rate, and one rotary kiln has two billion purchase, maintenance and maintenance costs, so that the rotary kiln cannot be popularized and used at all.

EXAMPLE five
The discharging machine is a temperature-reducing oxygen-isolating discharging machine 18. The solid residue remained in the cracking kettle 4 is discharged to a movable ash residue box 19 through a temperature-reducing oxygen-isolating discharging machine 18 and is transported away. The temperature-reducing and oxygen-isolating discharging machine 18 comprises a screw conveyer 18.4, an oxygen-isolating discharging motor 18.7 and a nitrogen inlet 18.1, wherein a rotating shaft of the screw conveyer 18.4 is connected with the oxygen-isolating discharging motor 18.7; the nitrogen inlet 18.1 is connected with a nitrogen supply device; the screw conveyer 18.4 is provided with a solid residue inlet 18.2, a solid residue outlet 18.6, a water inlet 18.3 and a water outlet 18.5.

EXAMPLE six
To improve power capacity, circular waveguide transmission is used. Circular waveguides have a greater power capability than rectangular waveguides. Rectangular waveguide output by the microwave generating device is converted into circular waveguide by a rectangular-circular transition 16 waveguide to be injected into the cracking kettle 4.

EXAMPLE seven
The two feed waveguides N1, N2 may back up each other, and when one feed waveguide fails, the other feed waveguide may be activated without affecting the operation. As shown in fig. 1 and 2, two feeding waveguides N1 and N2 are respectively connected to two microwave generators (including a microwave generator and a power supply). The first microwave generator 10 is connected to an angled waveguide, which is connected to a circulator 12, the circulator 12 is connected to a coupler 14, the coupler 14 is connected to a rectangular waveguide, which is connected to a circular waveguide via a rectangular-circular transition 16 waveguide, which extends into a feed waveguide N1. The second microwave generator 20 is connected to an elbow waveguide, which is connected to the circulator 12, the circulator 12 is connected to the coupler 14, the coupler 14 is connected to a rectangular waveguide (the straight waveguide 11 shown in fig. 1), which is connected to a circular waveguide by a rectangular-circular transition 16 waveguide, which extends into the feed waveguide N2. Three screw adapters 15 are provided on the rectangular waveguide.
Further, the circulator 12 is also connected to a water load 13, and the water load 13 can absorb the reflected power from the cracking kettle and play a role in protecting the microwave source (microwave generator).
The circulator 12 is a one-way device for microwave transmission, and when used together with the water load 13, the reflected power generated in the cracking kettle 4 can be transmitted to the water load 13, the water load 13 converts the reflected power into heat after absorption and dissipates the heat, and the reflected power is prevented from being transmitted to a microwave source (microwave generator) to influence the stable use of the microwave source.
The coupler 14 can couple out small power below 100mw in a high-power microwave environment for detecting the magnitude of microwave power and whether power transmission is normal. The coupler 14 is connected to a power meter 29 through a cable 28 (coaxial cable), and the power meter 29 is used for displaying specific power values.
The straight waveguide 11 and the bent waveguide are devices for conducting microwave power, which is conducted from a microwave source to the cracker 4 and fed.
The reflected power generated in the cracker kettle 4 will reduce the efficiency of the cracker kettle 4, and at the same time, the reflected microwave power will interfere with the stable operation and service life of the microwave source, and the three-pin coordinator 15 can adjust the reflected power within a certain range to keep the reflected power at the lowest possible level.
The waveguide pressure window 17 is a sealed device made of microwave-transparent material, which can isolate the air flow and does not affect the microwave power passing.
The transition waveguide (rectangular-circular transition 16) converts a rectangular waveguide into a circular waveguide, allowing more uniform microwave power feed to the cracker 4.
Example eight
In order to prevent the microwave leakage from causing electromagnetic radiation damage to the environment, electromagnetic shielding is needed to the cracking kettle 4, and the invention adopts a labyrinth choke 21 to shield the microwave leakage. As shown in fig. 1, at the cracking kettle 4b (i.e. the intersection connection part of the lid of the cracking kettle 4, the stirring shaft and the labyrinth choke), which is a weak link of the whole cracking kettle 4, the microwave will converge at the b position when reflected in the cracking kettle 4, and the high-intensity microwave will break down the b position, so that a microwave dynamic sealing device, i.e. the labyrinth choke 21, is required at the b position to protect the weak link.
The labyrinth choke 21 is constructed as shown in fig. 8, and the labyrinth gap corresponds to a radiation resistance. External electromagnetic field with close frequency can excite current in the choke through the radiation resistor; so that the input impedance of the outer layer (see fig. 8) is connected in series to a point near λ/4 of the inner layer; but Z isinAbout 0, so that the current flows through this Z on the slotin(ZinInput impedance) becomes smaller order of magnitude, greatly suppresses leakage power, realizes the effect of choking, and thenThereby realizing electromagnetic sealing. The weak link b can be protected by adopting the design, and microwave ignition is avoided.
Example nine
