Description

Technical Field

[0001] This utility model relates to the field of sulfonated acid slag recycling technology, specifically a mixing reaction vessel for sulfonated acid slag recycling. Background Technology

[0002] Sulfonated acid slag recovery refers to the process of treating viscous hazardous waste, mainly composed of waste sulfuric acid and organic impurities, generated during the sulfonation production process, through a series of physical and chemical treatments to achieve resource utilization and harmless treatment. The sulfonated acid slag recycling mixing reactor is a key pretreatment device on the sulfonated acid slag resource recovery production line. It is a specialized reaction vessel that uses mechanical stirring, heating, and temperature control to homogenize, adjust the concentration, and reduce the viscosity of the raw sulfonated acid slag, which has complex composition and high viscosity, to prepare a stable, homogeneous mixture that meets the feed requirements of subsequent core processes.

[0003] During the use of the reactor, the waste heat of the discharged material is usually not recovered, which means that the heat energy contained in the material after the reaction is directly wasted. In addition, the heat loss of the reactor is large, and the heating process of the next batch of material needs to start from room temperature. The consumption of steam or electricity will increase sharply, resulting in high production costs. Utility Model Content

[0004] The purpose of this invention is to provide a blending reaction vessel for recovering sulfonated acid residue, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blending reactor for recovering sulfonated acid residue, comprising a reactor body, a reactor cover, and a feed pipe. The reactor cover is connected to the top of the outer wall of the reactor body, and a feed pipe is embedded in the outer side of the top of the reactor cover. A servo motor is connected to the middle of the top of the reactor cover via a bracket, and a rotating column is fixedly connected to the bottom output end of the servo motor. A stirring rod is sleeved and fixed to the outer wall of the rotating column. A discharge pipe is connected to the middle of the bottom of the reactor body, and a heating chamber is opened inside the discharge pipe. An air inlet pipe is connected to one side of the top of the heating chamber, and an air outlet pipe is connected to the other side of the top of the heating chamber. The air inlet pipe introduces high-temperature steam into the heating chamber for heating the reaction vessel; The outer wall of the reactor body is fitted with a heat insulation sleeve in the middle, and a liquid storage chamber is opened inside the heat insulation sleeve. The bottom output end of the discharge pipe is fixedly connected to a filter tank, and the bottom output end of the filter tank is connected to a liquid outlet pipe. A water collection tank is connected to one side of the outer wall of the liquid outlet pipe, and a heat exchange box is installed inside the water collection tank. The insulation jacket is used to keep the reactor warm, the filter tank is used to separate the solid and liquid materials discharged from the discharge pipe, and the water collection tank, in conjunction with the heat exchange box, is used to recover the heat of the liquid materials.

[0006] The reactor is insulated by recovering the heat from the discharged materials.

[0007] Preferably, the stirring rods are evenly spaced, the heat exchange box has an "O" shaped structure, and a support foot is fixedly connected to the bottom of the heat exchange box, the bottom of the support foot being connected to the bottom of the inner wall of the water collection tank.

[0008] A servo motor drives a rotating column to rotate, which in turn drives a stirring rod to rotate, thereby stirring the materials inside the reactor.

[0009] Preferably, a conveying pipe is installed on one side of the bottom of the water collection tank, and a No. 1 pipe is connected to the bottom output end of the heat exchange tank. The No. 1 pipe has a "C" shaped structure, and a high-pressure water pump is connected to one side of the top of the No. 1 pipe. The bottom end of the high-pressure water pump is fixedly connected to the top of the water collection tank.

[0010] The liquid material that has completed heat exchange is discharged from the water collection tank through the conveying pipeline; the high-pressure water pump is started so that the high-temperature water in the heat exchange tank is discharged through the No. 1 pipeline.

[0011] Preferably, a second pipe is installed on one side of the outer wall of the high-pressure water pump, and an inlet water pump is connected to the top of the second pipe. The outer wall of the inlet water pump is fixedly connected to the insulation sleeve, and the output end of the inlet water pump extends into the liquid storage chamber.

[0012] Water is sent to the inlet pump through pipe number two. The inlet pump is then started to send the high-temperature water to the liquid storage chamber inside the insulation jacket. Since the inner wall of the insulation jacket wraps around the main body of the reactor, the high-temperature water entering the insulation jacket will cause its temperature to rise, and then the insulation jacket will be used to keep the reactor warm.

[0013] Preferably, the top input end of the heat exchange box is connected to a No. 3 pipe, and the top end of the No. 3 pipe is connected to a drain water pump. One side of the outer wall of the drain water pump is fixedly connected to the insulation sleeve, and the input end of the inlet water pump extends into the liquid storage chamber.

[0014] When the temperature of the water in the storage chamber decreases, the drain pump is started to return the water in the storage chamber to the heat exchange box through pipe No. 3.

[0015] As can be seen from the above, the sulfonated acid residue recycling blending reactor provided by this utility model has the following beneficial effects.

[0016] 1. By recovering heat energy through waste heat from materials, heating medium, and reactor insulation, the originally wasteful low-grade heat energy is converted into useful insulation heat energy. This closed-loop circulation system significantly reduces the reactor's dependence on external steam during initial heating and temperature maintenance, directly reducing energy consumption and operating costs in the production process.

[0017] 2. The rotating column drives the stirring rod to rotate, which makes the material evenly mixed and avoids violent local reactions; and the filter tank separates the solid waste residue, which is convenient for classification and disposal or further resource utilization, reducing the pressure of final solid waste disposal.

An air inlet pipe 9 is connected to one side of the top of the heating chamber 8, and an air outlet pipe 10 is connected to the other side of the top of the heating chamber 8. Inlet pipe 9 introduces high-temperature steam into heating chamber 8 for heating the reaction vessel; A heat insulation sleeve 11 is fitted around the middle of the outer wall of the reactor body 1, and a liquid storage chamber 12 is opened inside the heat insulation sleeve 11. A filter tank 13 is fixedly connected to the bottom output end of the discharge pipe 7, and a liquid outlet pipe 14 is connected to the bottom output end of the filter tank 13. A water collection tank 15 is connected to one side of the outer wall of the liquid outlet pipe 14, and a heat exchange box 17 is installed inside the water collection tank 15. The insulation jacket 11 is used to keep the reactor warm, the filter tank 13 is used to separate the solid and liquid materials discharged from the discharge pipe 7, and the water collection tank 15, together with the heat exchange box 17, is used to recover the heat of the liquid materials. The stirring rods 6 are evenly spaced, the heat exchange box 17 has an "O" shaped structure, and the bottom of the heat exchange box 17 is fixedly connected to the support foot 18, the bottom of the support foot 18 is connected to the bottom of the inner wall of the water collection tank 15; a conveying pipe 16 is installed on one side of the bottom of the water collection tank 15, and the bottom output end of the heat exchange box 17 is connected to a first pipe 19, which has a "C" shaped structure. A high-pressure water pump 20 is connected to one side of the top of the first pipe 19, and the bottom of the high-pressure water pump 20 is fixedly connected to the top of the water collection tank 15. Connect; a second pipe 21 is installed on one side of the outer wall of the high-pressure water pump 20, and an inlet water pump 22 is connected to the top of the second pipe 21. The outer wall of the inlet water pump 22 is fixedly connected to the insulation sleeve 11, and the output end of the inlet water pump 22 extends into the liquid storage chamber 12; the top input end of the heat exchange box 17 is connected to a third pipe 24, and the top of the third pipe 24 is connected to a drain water pump 23. The outer wall of the drain water pump 23 is fixedly connected to the insulation sleeve 11, and the input end of the inlet water pump 22 extends into the liquid storage chamber 12.

[0022] In practice, the sulfonated acid slag is removed by a vibrating screen to remove large solid impurities, preventing blockage of the reactor inlet and agitator. The pretreated acid slag is temporarily stored in a corrosion-resistant storage tank to prevent the viscosity from increasing due to low temperature, which would affect the flowability of the feed. The acid slag, diluent, and catalyst are sequentially injected into the reactor body 1 through the metering feed pipe 3. The servo motor 4 on the reactor cover 2 is started, which drives the rotating column 5 and the connected stirring rod 6 to rotate, forcibly stirring the materials in a 30-minute cycle. This process aims to precisely adjust the sulfuric acid concentration of the mixture to 30%~50% and form a uniform viscous mixture, thereby preventing side reactions caused by excessively high local concentrations. After mixing, high-temperature steam is introduced into the heating chamber 8 surrounding the reactor through the air inlet pipe 9, gradually raising the temperature of the material inside the reactor to 100-120℃ according to process requirements. Volatile waste gases generated during the reaction are collected through the waste gas outlet at the top of the reactor and discharged to the alkali absorption tower for harmless treatment, ensuring that the tail gas meets emission standards before being released. After the reaction is completed, stirring is stopped and the heating system is shut off sequentially, and finally the reacted material is discharged through the discharge pipe 7 at the bottom.

[0023] See Figure 2 and Figure 3 The material discharged from the discharge pipe 7 enters the filter tank 13 for solid-liquid separation. Solid residue is retained in the filter tank 13, while the liquid material enters the water collection tank 15 through the liquid outlet pipe 14. See Figure 5 , Figure 6 and Figure 7 The liquid material then contacts the inner wall of the heat exchange box 17 via the support feet 18. As the liquid material is continuously introduced into the water collection tank 15, its liquid level rises until it submerges the heat exchange box 17. During this process, the liquid material indirectly exchanges heat with the heat-absorbing medium circulating inside the heat exchange box 17 through the wall, thereby transferring its own waste heat to the medium and raising its temperature. After the heat exchange is completed, the cooled liquid material is discharged from the system through the conveying pipe 16. The high-pressure water pump 20 is started, and the heated medium in the heat exchange box 17 is discharged through the first pipeline 19 and transported to the liquid inlet pump 22 through the second pipeline 21. The liquid inlet pump 22 pumps the high-temperature medium into the liquid storage chamber 12 inside the insulation jacket 11 that surrounds the reactor body 1. The high-temperature medium circulates in the liquid storage chamber 12, using its heat energy to continuously keep the reactor body 1 warm, effectively reducing heat loss from the reactor body; When the temperature of the medium in the storage chamber 12 drops to the set lower limit, the drain pump 23 is started to return the cooled medium to the heat exchange box 17 through the No. 3 pipe 24 for reheating. This closed-loop circulation system can continuously recover the waste heat of the discharged material for use in the reactor insulation, which significantly reduces the heating energy consumption of the system in subsequent batches of reaction. Furthermore, the heat exchange box 17 can be replenished with water through the water inlet pipe connected to it.

[0024] By recovering heat from waste material, heating medium, and reactor insulation, the originally wasteful low-grade heat energy is converted into useful insulation heat energy. This closed-loop circulation system significantly reduces the reactor's dependence on external steam during initial heating and temperature maintenance, directly reducing energy consumption and operating costs in the production process. The rotating column 5 drives the stirring rod 6 to rotate, so that the material is evenly mixed and avoids violent local reactions; and the filter tank 13 separates the solid waste residue, which is convenient for classification and disposal or further resource utilization, reducing the pressure of final solid waste disposal.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
