Description

Technical Field

[0001] This utility model belongs to the technical field of lubricating oil additive production equipment, specifically a reaction device for producing lubricating oil additives. Background Technology

[0002] T321 isobutylene sulfide is an important extreme pressure anti-wear additive, widely used in gear oils, hydraulic oils, and other lubricants. Its production process typically involves a sulfidation reaction, where isobutylene reacts with sulfur or hydrogen sulfide under a catalyst to produce sulfide olefins. With increasing environmental protection requirements and higher production quality standards, uniform reaction and the treatment of harmful gases are crucial in the production of chemicals. However, existing lubricant additives such as T321 isobutylene sulfide (sulfide olefin) production processes suffer from uneven reaction and the generation of harmful gases. Existing production equipment cannot effectively ensure a more uniform reaction, and direct emission of untreated exhaust gases causes significant pollution. Therefore, a device is needed to design that can achieve a more uniform reaction through stirring and effectively treat harmful gases. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that can make the reaction more uniform through stirring and effectively treat harmful gases, thereby solving the problems that existing devices cannot make the reaction more uniform and the treatment effect of harmful gases is not good.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a reaction device for producing lubricating oil additives, comprising a reaction tank and a condenser. The reaction tank has a discharge port at the bottom and a feed port at the top. The reaction tank and the condenser are connected by an exhaust pipe. A stirring shaft is installed inside the reaction tank. The stirring shaft is sequentially connected from top to bottom to a paddle stirring blade, a double-helix stirring blade, and a turbine stirring blade. The stirring shaft is driven by a motor. A processing box is fixedly connected to the top of the condenser and has a condenser pipe installed inside. The processing box is divided into a chamber by a vertically installed baffle in the middle. The two chambers are equipped with a strip-shaped hole at the bottom of the baffle. A water pipe is sleeved on the outside of the straight section of the condenser tube, and a spiral guide plate is installed on the inside of the straight section. One end of the condenser tube passes through the side wall of the condenser box and is connected to one end of the exhaust pipe. The other end passes through the top wall of the condenser box and extends to one side of the two chambers. A vertically arranged reaction layer is fixedly connected in the two chambers. Several horizontally arranged activated carbon layers are fixedly connected in the first chamber. An air outlet is opened at the top of the first chamber. A liquid outlet pipe is fixedly connected to the bend at the lower end of the condenser tube. The lower end of the liquid outlet pipe passes through the bottom wall of the condenser box and extends outward.

[0005] Furthermore, an electric heating layer is provided on the outside of the reaction vessel.

[0006] Furthermore, rake teeth are fixedly connected to the sidewall of the turbine stirring blade.

[0007] Furthermore, the other end of the exhaust pipe is connected to the top of the reaction vessel.

[0008] Furthermore, the water pipes are connected by connecting pipes, and a slide valve is installed on both the liquid outlet pipe and the discharge port.

[0009] This utility model has the following advantages compared with the prior art:

[0010] 1. This utility model, by setting three different stirring blades, can fully agitate the raw materials in the reaction tank to react evenly, thereby improving product quality. By setting folded condenser tubes and sleeved with water pipes on the straight sections of the condenser tubes, harmful gases can be condensed into liquids for collection. By setting a treatment box on the condenser, multiple purification of harmful gases can be carried out, improving treatment efficiency and avoiding exhaust gas pollution of the air. By setting a reaction layer and immersing it in an alkaline solution, some sulfide gases can be dissolved, improving purification efficiency. By setting an activated carbon layer, residual harmful gases can be adsorbed, effectively improving the treatment efficiency of harmful gases and removing 99% of harmful gases.

[0011] 2. By setting a spiral guide plate, this utility model can slow down the time it takes for gas to pass through the condenser tube, thereby improving the condensation effect. At the same time, it can guide the condensed and liquefied liquid to the bend at the bottom of the condenser tube. By setting rake teeth on the turbine stirring blades, it can improve the efficiency of stirring at the bottom of the reaction tank, crush the raw materials at the bottom, and improve product quality.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 4 The apparatus shown is a reaction vessel for producing lubricating oil additives, comprising a reaction tank 1 and a condenser 2. The reaction tank 1 has a discharge port 19 at the bottom and a feed port 13 at the top. To ensure the sealing of the reaction tank, a sealing cap is provided on the feed port 13. To facilitate the handling of harmful gases generated, the reaction tank 1 and the condenser 2 are connected by an exhaust pipe 7. To agitate the reactants, a stirring shaft 21 is installed inside the reaction tank 1. The stirring shaft 21 is vertically positioned, with its upper end fixedly connected to the output end of a motor 12. To ensure thorough agitation, paddle-type stirring blades 15 and double-helix stirring blades 1 are sequentially fixedly connected to the stirring shaft 21 from top to bottom. 6. The turbine agitator 17 and the paddle agitator 15 are set at an inclination angle of 60 degrees, tilting downwards to push the material downwards. The double helix agitator 16 pushes the material in the middle up and down, while the turbine agitator 17 at the lower end lifts the material at the bottom, stirring the material at the bottom to prevent sedimentation. The agitator shaft 21 is driven by the motor 12, which is fixedly connected to the top of the reaction tank 1. The output end passes through the top wall of the reaction tank 1 and is fixedly connected to the upper end of the agitator shaft 21. For condensation treatment, some gas and water vapor are liquefied and collected together. A processing box 3 is fixedly connected to the top of the condensation box 2, and a condenser tube 8 is installed inside. The condenser tube 8 is vertically folded and spiraled to... To perform multiple treatments, the treatment chamber 3 is divided into a first chamber and a second chamber by a vertically installed baffle 4. To allow the gas to enter the first chamber after being treated in the second chamber, a slotted hole 22 is provided at the bottom of the baffle 4. To cool the gas entering the condenser tube 8, a water pipe 10 is fitted outside the straight section of the condenser tube 8, and a spiral guide plate 9 is installed inside the straight section. To ensure condensation efficiency, water at a temperature below 10 degrees Celsius is circulated through the water pipe 10. The spiral guide plate 9 allows the gas to remain in the condenser tube 8 for a longer time, increasing the condensation effect, and directs the liquefied liquid along the condenser guide plate 9 to the bend at the lower end of the condenser tube 8. One end of the condenser tube 8 penetrates the side of the condenser chamber 2. One end of the wall is connected to the exhaust pipe 7, and the other end extends through the top wall of the condenser 2 to the right side of the second chamber. A vertically arranged reaction layer 5 is fixedly connected in the second chamber. In order to react the sulfidation gas, an alkaline solution is impregnated on the reaction layer 5. In order to ensure the gas flow path, the reaction layer 5 is set on the left side of the output end of the condenser pipe 8. Several horizontally arranged activated carbon layers 6 are fixedly connected in the first chamber. The activated carbon layers 6 are all set above the strip hole 22. An outlet 20 is opened at the top of the first chamber. In order to facilitate the collection of condensed liquid, a liquid outlet pipe 11 is fixedly connected at the bend of the lower end of the condenser pipe 8. The lower end of the liquid outlet pipe 11 extends outward through the bottom wall of the condenser 2.

[0019] To improve reaction efficiency and increase product quality, an electric heating layer 14 is installed on the outside of the reaction vessel 1.

[0020] In order to crush the material at the bottom, rake teeth 18 are fixedly connected to the side wall of the turbine mixing blade 17.

[0021] To ensure that the gas generated in the reaction tank 1 is sent into the condenser 2, the other end of the exhaust pipe 7 is connected to the top of the reaction tank 1, and a small-power induced draft fan is installed on the exhaust pipe 7 to ensure that the gas is slowly sent into the condenser 8.

[0022] To ensure the water pipes 10 are connected, the water pipes 10 are connected by connecting pipes. The connecting pipes are U-shaped and connect the tops of the water pipes 10. To facilitate the control of liquid and material discharge, slide valves are installed on the liquid discharge pipe 11 and the material discharge port 19.

[0023] The specific working process of this utility model is as follows:

[0024] When producing lubricating oil additives, the raw materials are first placed into the inlet 13, and then the sealing cap on the inlet 13 is closed. At this time, the motor 12 is turned on, causing the motor 12 to drive the stirring shaft 21 to rotate. The stirring shaft 21 drives the paddle stirring blade 15, the double spiral stirring blade 16, and the turbine stirring blade 17 to rotate together, so that the raw materials in the reaction tank 1 can be uniformly mixed and reacted. The materials that settle at the bottom and the clumps are crushed by the turbine stirring blade 17 and pushed upward. At the same time, the electric heating layer 14 is turned on to make the reaction tank 1 uniformly heated. The harmful gases produced by the reaction are sent to the cooling system through the exhaust pipe 7 at the top of the reaction tank 1. Inside the condenser tube 8, the gas flow speed is slowed down by the spiral guide plate 9. At this time, water below 10 degrees Celsius is introduced into the water pipe 10 for condensation. The condensed liquid flows to the bend at the lower end of the condenser tube 8 for collection. The remaining gas enters the right side of the second chamber of the treatment box 3 and reacts with the alkaline solution through the reaction layer 5 to remove some harmful gases. The remaining small amount of gas enters the first chamber through the strip hole 22, and after being adsorbed by two layers of activated carbon 6, it is discharged from the gas outlet 20. Producing lubricating oil additives in the above manner can make the reaction more uniform, improve product quality, and improve the efficiency of tail gas treatment.
