[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including a..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements; for example, xx phase is not a fixed word, but a state of matter, such as the liquid phase of a metal, which is the molten state of the metal, and does not specifically refer to a fixed object. For example, the "slag phase" in this application refers to the residue after the target fuel is filtered out after the straw powder and catalyst are treated with heat transfer oil, or a mixture of the residue and heat transfer oil. If the two liquid phases are mixed but not miscible, they are separated into oil phase and water phase by density stratification. The water phase is not water in the sense of a noun, but a pictographic expression made to distinguish the liquid after extraction. It may also be alcohol or vinegar, the purpose of which is to distinguish the two liquid mixtures in terms of expression. Figure 1As shown, a supporting separation reactor for producing straw oil based on pulse cracking includes: a feed inlet (A), a leaking bin (B), a pulser (C), a liquid receiver (D), a liquid level indicator (F), an evaporator (G), a heater (H), a cooling tower (L), a liquid storage bin (M), and a reactor body (T); a valve 1 (A2) is provided between the feed inlet (A) and the leaking bin (B), an air extraction interface (A1) is provided on the upper side of the leaking bin (B), the bottom of the leaking bin (B) is a mesh structure, and a liquid receiver (D) is provided at the lower end, and a magnetron (C1) is provided inside the pulser (C). The pulser (C) is arranged on the side of the reactor body (T) and directly opposite the leakage chamber (B); the liquid receiver (D) is connected to the evaporation tank (G) pipeline and is provided with a valve 2 (E); the evaporation tank (G) is provided with a liquid level indicator (F) on the side and a heater (H) at the lower end; the evaporation tank (G) is connected to a cooling tower (L) through a delivery pipe (L1); the cooling tower (L) is provided with a water inlet (L2) and a water outlet (L3) for condensation cooling, and the lower end is connected to a liquid storage tank (M); the upper end of the liquid storage tank (M) is provided with a liquid intake port (P) and the lower end is provided with a liquid discharge port (N).

[0015] Furthermore, the mesh structure provided at the bottom of the leak bin (B) has a mesh size of 20 to 50.

[0016] Furthermore, the reactor body (T) is a detachable device.

[0017] Furthermore, the power of the pulser (C) is above 1000W.

[0018] Working process and principle of this utility model:

[0019] After opening valve 1 (A2), the straw powder is poured into the feed port (A), and then the straw powder enters the leak bin (B). Due to the mesh structure at the bottom of the leak bin (B), the straw powder cannot enter the liquid receiver (D). At this time, the vacuum pump (A1) connected to the vacuum interface is turned on to put the reactor body (T) in an oxygen-free environment. At the same time, the pulser (C) is turned on, and the magnetron (C1) emits a high-temperature electromagnetic pulse in the direction of the leak bin (B). The straw powder is gradually carbonized after the cracking reaction under the oxygen-free high-temperature pulse, and bio-oil is precipitated at the same time. The bio-oil drips into the liquid receiver (D), and the valve 2 (E) is opened, and the oil flows into the evaporation tank (G). When When the liquid level in the evaporator (G) reaches the position of the liquid level indicator (F), valve 2 (E) is closed and the heater (H) is started at the same time. After the oil is subjected to high temperature, steam is generated and enters the cooling tower (L) along the delivery pipe (L1). Since the water inlet (L2) and the water outlet (L3) are cooled by circulating water, the oil vapor is condensed and cooled, and the liquid phase oil flows into the liquid storage tank (M). The liquid phase oil is taken out from the liquid extraction port (P) for testing. If it meets the liquid phase oil quality of internal combustion engine fuel, the drain port (N) is opened for collection and storage. Since the reactor body (T) is a detachable device, the carbonized straw powder can be taken out and reinstalled, and the above operation is repeated after adding straw powder.

The appended claims are intended to claim the broadest possible scope that can be imagined, and the embodiments presented herein are only descriptions of selected implementations based on the combination of all possible embodiments. Therefore, the applicant's intention is that the appended claims are not limited by the selection of examples that illustrate the features of the present invention. Moreover, advances in science and technology will form possible equivalents or sub-alternatives that are not currently considered due to inaccuracies in language expression, and these changes should also be interpreted as being covered by the appended claims where possible.
