Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a chemical product concentration reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors need to be used in conjunction with cooling devices. Reactors are also used in pesticide production, such as the concentration reaction vessel (authorized announcement number "CN212942902U"). Its structure includes a base supporting a reaction vessel body, which is ellipsoidal and jacketed. A stirring shaft is installed along the axis of the reaction vessel body. The upper and lower ends of the stirring shaft pass through the reaction vessel body via bearing seals. Spiral stirring blades are installed on the stirring shaft, with the radius of the blades gradually decreasing from the center to both ends. This invention is reasonably designed, achieving rapid and uniform mixing of reactants through the special design of the reaction vessel body shape. Furthermore, the spiral cooling coils laid within the jacket of the vessel body achieve cooling, making it highly valuable for practical applications.

[0003] Traditional concentration reactors are used to concentrate pesticides. During the pesticide concentration process, steam and harmful gases are inevitably generated. Because these reactors are not equipped with corresponding treatment devices such as condensation recovery and adsorption purification, the steam and harmful gases generated during operation cannot be effectively collected and purified. The steam and harmful gases are directly discharged into the surrounding air, and over time, they cause serious pollution to the surrounding ecological environment. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Traditional concentration reactors concentrate pesticides during use. Inevitably, steam and harmful gases are generated during the pesticide concentration process. Because these reactors are not equipped with corresponding treatment devices such as condensation recovery and adsorption purification, the steam and harmful gases generated during operation cannot be effectively collected and purified. The steam and harmful gases are directly discharged into the surrounding air, which, over time, causes serious pollution to the surrounding ecological environment.

[0021] In view of this, the present invention provides a chemical product concentration reactor. When the heater is working, the pesticide inside the top and bottom shells of the reactor is concentrated. The servo motor drives the stirring rod to rotate, so that the pesticide is heated more evenly. The heat in the exhaust gas is recovered through the exhaust gas treatment mechanism to reduce energy waste. The exhaust gas is sprayed out from the nozzle through the coil, so that the exhaust gas comes into contact with water to generate ammonium chloride, thus completing the treatment of the exhaust gas and not causing pollution to the environment.

[0022] Example 1: By Figure 1 , 2 As can be seen from points 3 and 4, a chemical product concentration reactor includes a processing tank 1. A water inlet pipe 3 is connected to the front of the processing tank 1. A reactor bottom shell 4 is fixedly connected to the outer wall of the processing tank 1. A reactor top shell 5 is fixedly connected to the top of the reactor bottom shell 4. An exhaust gas treatment mechanism 2 is provided inside the processing tank 1. The exhaust gas treatment mechanism 2 includes: a first water inlet pipe 21, which is connected to the top of the processing tank 1; and a coil 22, which is fixedly connected to the inner wall of the processing tank 1 and extends to the outside of the processing tank 1. The outer wall of the coil 22 is fixedly connected to the inner wall of the reactor top shell 5 and extends into the interior of the reactor top shell 5. The first drain pipe 23 is connected to the inner wall of the treatment tank 1 on the side away from the bottom shell 4 of the reactor; the nozzle 24 is connected to the bottom of the coil 22 and is fixedly connected to the lower inner wall of the treatment tank 1; the second drain pipe 25 is connected to the lower inner side of the treatment tank 1 away from the bottom shell 4 of the reactor; wherein, the waste gas enters the interior of the coil 22, and water is added to the top of the treatment tank 1 through the first water inlet pipe 21. The waste gas inside the coil 22 transfers heat to the water above the treatment tank 1 to achieve heat recovery. The waste gas is sprayed out from the nozzle 24 through the coil 22. The waste gas reacts with the water to treat the harmful substances.

[0023] In the specific implementation process, it is worth noting that the water inlet pipe 3 can add water to the bottom of the treatment tank 1. A sealing gasket is set between the bottom shell 4 and the top shell 5 of the reaction vessel. Valves are fixedly connected to the outer walls of the first drain pipe 23 and the second drain pipe 25. The valves control whether the first drain pipe 23 and the second drain pipe 25 drain water outward. Water is added to the top of the treatment tank 1 from the first inlet pipe 21. The exhaust gas inside the coil 22 transfers heat to the water above the treatment tank 1 to achieve heat recovery. The exhaust gas is sprayed outward from the nozzle 24 through the coil 22. The ammonia and hydrogen chloride in the exhaust gas react with the water inside the treatment tank 1 to treat harmful substances. Ammonia is an alkaline gas and hydrogen chloride is an acidic gas. The two will undergo a neutralization reaction in the water to generate ammonium chloride. This reaction will promote the dissolution of ammonia and hydrogen chloride in the water, so that they can be absorbed and treated by the water more effectively.

[0024] Furthermore, a servo motor 7 is fixedly connected to the top of the reactor top shell 5, and a stirring rod 9 is fixedly connected to the output end of the servo motor 7. The outer wall of the stirring rod 9 is rotatably connected to the inner wall of the reactor top shell 5 through a bearing.

[0025] In the specific implementation process, it is worth noting that the model of the servo motor 7 is not limited, as long as it meets the usage requirements. The servo motor 7 provides power to the stirring rod 9. When the stirring rod 9 rotates, it stirs the pesticide inside the bottom shell 4 and the top shell 5 of the reactor.

[0026] Furthermore, a feed pipe 8 is fixedly connected to the inner wall of the reactor top shell 5, and one end of the feed pipe 8 extends into the interior of the reactor top shell 5.

[0027] In the specific implementation process, it is worth noting that the pesticide enters the top shell 5 and bottom shell 4 of the reactor from the feed pipe 8;

[0028] Furthermore, a discharge pipe 10 is fixedly connected to the inner wall of the reactor bottom shell 4, two heaters 11 are fixedly connected to the lower part of the inner wall of the reactor bottom shell 4, and a support frame 12 is fixedly connected to the bottom of the reactor bottom shell 4.

[0029] In the specific implementation process, it is worth noting that a valve is fixedly connected to the outer wall of the discharge pipe 10. The valve controls whether the concentrated pesticide is discharged from the discharge pipe 10. The concentrated pesticide in the bottom shell 4 of the reactor is discharged outward from the discharge pipe 10. The model of the heater 11 is not limited, as long as it meets the usage requirements. The support frame 12 makes the bottom shell 4 of the reactor more stable in use.

[0030] Specifically, when using this chemical product concentration reactor, the pesticide to be concentrated is added into the reactor bottom shell 4 and reactor top shell 5 through the feed pipe 8. The operator controls the heater 11 via an external control panel. The heater 11 concentrates the pesticide. When the servo motor 7 is working, it stirs the pesticide through the stirring rod 9, ensuring uniform heating. The concentrated pesticide is discharged out through the discharge pipe 10. Water is added to the bottom of the treatment tank 1 through the water inlet pipe 3, and water is added to the top of the treatment tank 1 through the first water inlet pipe 21. The exhaust gas generated during operation enters the interior of coil 22. The exhaust gas transfers heat to the water above the treatment tank 1 through coil 22. The heated water is discharged from the first drain pipe 23. The exhaust gas enters the interior of nozzle 24 from the bottom of coil 22 and is discharged from nozzle 24. The exhaust gas contains ammonia and hydrogen chloride, which will undergo a neutralization reaction in the water to produce ammonium chloride. This reaction will promote the dissolution of ammonia and hydrogen chloride in the water, so that they can be absorbed and treated more effectively by the water. The treated water is discharged from the second drain pipe 25.

[0031] Example 2: From Figure 1 , 2 As shown in section 4, a cleaning mechanism 6 is provided inside the reactor top shell 5. The cleaning mechanism 6 includes: two connecting rods 61, both fixedly connected to the inner wall of the reactor top shell 5; a water storage ring 62, fixedly connected to the bottom of the two connecting rods 61; multiple nozzles 63, all connected to the inside of the water storage ring 62; and a second water inlet pipe 64, connected to the inside of the water storage ring 62 and fixedly connected to the side of the inner wall of the reactor top shell 5 away from the treatment tank 1. One end of the second water inlet pipe 64 extends to the outside of the reactor top shell 5. Water inside the second water inlet pipe 64 enters the water storage ring 62 and is sprayed outward from the multiple nozzles 63 to clean the inner walls of the reactor top shell 5 and the reactor bottom shell 4.

[0032] In the specific implementation process, it is worth noting that the nozzles 63 are radially connected to the inside of the water storage ring 62. Clean water enters the inside of the water storage ring 62 from the second water inlet pipe 64, and the water inside the water storage ring 62 is sprayed outward from multiple nozzles 63.

[0033] Specifically, based on the above embodiment one, the second water inlet pipe 64 is connected to an external water pipe, and the cleaning water enters the interior of the water storage ring 62 from the second water inlet pipe 64. The water storage ring 62 sprays water outward from multiple nozzles 63, and the cleaning water cleans the inner walls of the reactor top shell 5 and the reactor bottom shell 4.
