Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of petrochemical processing, in particular to an asphalt hydrogenation reactor. Background Technique
[0002] Needle coke is a carbon material for producing large-size ultra-high power graphite electrodes and lithium battery anodes. It is divided into oil-based needle coke and coal-based needle coke according to different raw materials. The one produced from coal tar pitch or coal tar components is coal-based needle coke, and the one produced from petroleum heavy oil or petroleum asphalt as raw materials is oil-based needle coke. The production of both types of needle coke requires pretreatment of raw materials to remove impurities such as sulfur and nitrogen that affect the quality of needle coke. The hydrogenation method is one of the methods for pretreating needle coke raw materials. The hydrogenation method has attracted people's attention because it can effectively remove sulfur and nitrogen in raw materials while increasing the H / C ratio of raw materials. Hydrogenation can effectively reduce the sulfur and nitrogen content in raw materials, increase the H / C ratio and naphthene content of raw materials, and improve the rheological properties of raw materials. Compared with the corresponding aromatic hydrocarbons with the same number of rings, naphthenes have lower melting points. During the coking process, due to the presence of naphthene condensed polycyclic aromatic hydrocarbons, the liquid phase retention time is prolonged, the system viscosity is reduced, and the active free radicals are hydrogenated and stabilized due to the hydrogen transfer on the naphthene, restricting the excessive polymerization of raw materials and creating good conditions for producing high-quality needle coke;
[0003] The current hydrogenation process is that hydrogen and the material to be hydrogenated undergo a catalytic hydrogenation reaction in the presence of a hydrogenation catalyst. This hydrogenation method is to hydrogenate the raw material in the presence of a catalyst, and usually the reaction is carried out through a hydrogenation reactor;
[0004] However, the existing hydrogenation reactor cannot control the liquid level of the discharged material. If there is too much, it will overflow, and if it is too small, it will affect the use. Content of the Utility Model
[0005] The purpose of the utility model is to provide an asphalt hydrogenation reactor, which has the characteristics of realizing continuous quantitative discharging, simple equipment structure, high automation degree, adjustable discharging amount according to needs, convenient adjustment and flexible use.
[0006] To achieve the above purpose, the utility model provides the following technical solution: an asphalt hydrogenation reactor, including a hydrogenation reactor main body, a discharging box is arranged on one side of the hydrogenation reactor main body, two vertically arranged limiting rods are fixedly connected inside the discharging box, a floating plate is arranged inside the discharging box, two limiting holes are penetrated and opened on the upper end surface of the floating plate, the two limiting rods respectively pass through the two limiting holes, a screw rod is penetrated and threadedly connected to the top of the discharging box, an installation plate is fixedly connected to the bottom end of the screw rod, an infrared emitter is arranged on the lower end surface of the installation plate, and an infrared receiver is arranged at the center of the upper end surface of the floating plate.
[0007] For the convenience of exhausting gas and discharging liquid, as an optimization of the asphalt hydrogenation reactor of the present utility model, an exhaust port is fixedly connected to the top end of the discharge box, a liquid discharge port is fixedly connected to the bottom end of the side wall of the discharge box, and a solenoid valve is arranged on the outer wall of the liquid discharge port.
[0008] For introducing liquid and gas into the discharge box, as an optimization of the asphalt hydrogenation reactor of the present utility model, an overflow pipe is communicated between the hydrogenation reactor main body and the discharge box.
[0009] For the convenience of air intake and feed, as an optimization of the asphalt hydrogenation reactor of the present utility model, an air intake port is fixedly connected to the bottom of the hydrogenation reactor main body, and a feed port is fixedly connected to the lower part of the side wall of the hydrogenation reactor main body.
[0010] For supporting and fixing the discharge box, as an optimization of the asphalt hydrogenation reactor of the present utility model, a support plate is fixedly connected to the right side wall of the hydrogenation reactor main body, and the discharge box is fixedly connected to the upper end of the support plate.
[0011] For observing and adjusting the height of the infrared emitter, as an optimization of the asphalt hydrogenation reactor of the present utility model, an observation window is arranged on the outer wall of the discharge box, and scale lines are arranged on the outer wall of the observation window.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] The liquid material rises to the overflow pipe and then overflows from the overflow pipe into the interior of the discharge box. As the liquid level in the discharge box rises, it drives the floating plate to move upward continuously. The floating plate is limited by two limit rods to ensure stable lifting and lowering. The infrared emitter emits infrared signals, and the infrared receiver receives the signals for distance measurement. The distance threshold is set in advance through an external control system. When the floating plate rises and drives the infrared receiver to rise, and the actual distance is less than the set value, at this time, there is a certain amount of raw material in the discharge box. The control system receives the signal and controls the opening of the solenoid valve, so as to discharge a certain amount of raw material through the liquid discharge port. During the discharging process, the liquid level gradually drops, the floating plate moves downward, and when the distance is greater than the set value, the solenoid valve is controlled to close again to stop discharging. In this way, continuous quantitative discharging can be realized. The equipment has a simple structure, high automation degree. The mounting plate is installed at the bottom end of the screw. When the screw is rotated, the infrared emitter can be driven to move downward, thereby adjusting the height of the infrared emitter, so as to achieve the purpose of adjusting the discharging amount according to needs. The adjustment is convenient and the use is flexible. Description of the Drawings
