Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil-gas mixing equipment, in particular to a catalytic cracking reaction device for oil-gas mixing. Background Art
[0002] Catalytic cracking is one of the petroleum refining processes. It is a process in which heavy oil undergoes cracking reactions under the action of heat and a catalyst, transforming into cracked gas, gasoline, diesel, etc. Recently, some heavy oil catalytic cracking reactions have adopted the regenerant cooling technology. After applying this technology, the catalyst circulation rate increases, improving the catalyst-oil ratio, which is beneficial to enhancing the catalyst activity during the catalytic cracking reaction process. However, when the outlet temperature of the riser reactor remains unchanged, the bottom mixing temperature further decreases, resulting in a further increase in unvaporized oil and an increase in the coke formation rate.
[0003] For example, the publication number CN201320408596.X discloses "A Heavy Oil Catalytic Cracking Reactor". By strengthening the mixing of catalyst and oil-gas and enhancing heat transfer, heat is taken from the middle of the riser to effectively control the outlet temperature of the riser; the catalyst-oil ratio is increased, the catalyst activity during the catalytic cracking reaction process is improved, while the feed mixing temperature of the riser reactor is increased, the vaporization rate of heavy oil is increased, the unvaporized oil is reduced, the coking problems of the riser reactor and the settler are solved, and the coke formation rate of the device is reduced, the product yield is increased, and the product quality is improved (the olefin content and sulfur content in gasoline are reduced).
[0004] However, when the catalytic cracking reaction device for oil-gas mixing conducts catalytic cracking reactions, it is necessary to separate the liquid water in natural gas through a wire mesh demister. The existing wire mesh demisters are generally integrally arranged, so it is inconvenient to disassemble and repair the wire mesh demister. Moreover, when the water-natural gas mixture is blocked by the baffle, the water-natural gas mixture has a certain impact. After multiple impacts, the baffle will be damaged by the impact, which is not conducive to the catalytic cracking reaction process of oil-gas mixing. Summary of the Utility Model

[0027] Please refer to Figure 5 , the present utility model provides a technical solution for a catalytic cracking reaction device for oil-gas mixing: A catalytic cracking reaction device for oil-gas mixing, the blocking mechanism 10 includes a baffle 101, a second fixing plate 102, a movable rod 103, a second spring 104 and a rubber plug 105. The left end of the inner side of the baffle 101 is fixed with the second fixing plate 102. The right outer side of the movable rod 103 is sleeved with the second spring 104. The left end of the movable rod 103 is fixed to the right end of the rubber plug 105. The baffle 101 is fixed to the right side inside the separator housing 1. The rubber plug 105 is connected to the right end of the feed inlet 5. The inner cross-section of the baffle 101 is L-shaped. The second fixing plates 102 are vertically oppositely arranged on the upper and lower sides inside the baffle 101, so as to achieve the effect of assisting the translational guidance of the movable rod 103. The notches in the middle of the two baffles 101 are the same width as the movable rod 103, and the movable rod 103 is elastically matched with the lower left side of the second fixing plate 102 through the second spring 104, so as to achieve the effect of elastic reset of the rubber plug 105.
[0028] When in use, firstly, the fixed block 92 at the bottom of the wire mesh demister 91 is aligned and embedded with the connection between the left movable plate 93 and the right movable plate 94 on the inner side of the upper end of the support block 98, so that the left movable plate 93 and the right movable plate 94 can elastically reset the springs 97 on both sides through the fixed plates 96 on the left and right sides, thereby completing the quick installation effect of the wire mesh demister 91;
[0029] Then, the water-containing natural gas mixture entering from the feed port 5 impacts the rubber plug 105, so that the rubber plug 105 and the movable rod 103 are translated and adjusted along the connection between the two sets of fixed plates 102, and the spring 104 is elastically squeezed to achieve a buffering effect, thereby achieving an anti-impact blocking effect, and the elastic effect of the spring 104 is used to elastically reset the rubber plug 105 to the inside of the feed port 5 to achieve a blocking effect;
[0030] Then, the water-containing natural gas mixture is forced to flow downward under the obstruction of the rubber plug 105. Most of the liquid water remains at the bottom due to gravity, and the gas moves upward.

[0031] Similarly, the multi-channel parachute separator 8 is also for this purpose, and the wire mesh demister 91 on the top can condense smaller water droplets or water vapor to form larger water droplets, thereby achieving the separation of liquid water in the natural gas. The finished gas is transported to the pipeline network from the exhaust port 3, and the descending liquid is broken up and dispersed when it passes through the multi-channel parachute separator 8. In this way, the natural gas dissolved in the water can overflow, and the liquid gathered at the bottom is discharged under the control of the liquid level meter 6, thereby completing the effect of removing water from the natural gas.
[0032] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
[0033] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
