Description

Technical Field

[0001] This utility model relates to the field of synthesis tower technology, specifically a synthesis tower with a heat exchange structure. Background Technology

[0002] In the field of chemical production, synthesis towers are key pieces of equipment, undertaking the task of synthesizing various substances. During the operation of synthesis towers, a large amount of heat is generated. If heat exchange and cooling are not carried out in a timely manner, it will not only affect the efficiency of the synthesis reaction and the quality of the products, but may also cause safety accidents due to high temperatures. At the same time, the gases or liquids generated by the synthesis reaction often contain impurities, and direct discharge will cause serious environmental pollution.

[0003] Traditional synthesis towers have many shortcomings in their heat exchange and filtration systems. Some synthesis towers have simple heat exchange structures and low heat exchange efficiency, which cannot quickly and effectively remove the heat generated by the reaction, making it difficult to control the temperature inside the tower. In terms of filtration, some synthesis towers lack a complete filtration mechanism, making it difficult to filter the reaction products comprehensively and efficiently, resulting in excessive impurities in the emitted gases or liquids, which does not meet environmental protection requirements.

[0004] Publication number: CN202700483U. The urea synthesis tower of this utility model is conducive to energy transfer, reduces the temperature difference between the lower and upper parts of the synthesis tower, and makes the carbon dioxide conversion rate tend to be balanced; it can change the flow curve of the material in the synthesis tower, eliminate the retention of material on the tower wall, prevent material back mixing caused by density difference and turbulence, maintain the concentration gradient of urea in the tower, and improve the carbon dioxide conversion rate.

[0005] To address the aforementioned issues, traditional synthesis towers suffer from inadequate filtration systems, resulting in limited heat exchange efficiency and emissions that fail to meet standards. Therefore, we propose a synthesis tower with a heat exchange structure. Utility Model Content

The top of the water tank 17 is fixedly connected to the main flow pipe 4, and the bottom of the main flow pipe 4 is fixedly installed outside the water pump 16.

[0031] Structural Description: Exhaust Pipe 1: The interior is hollow. Its main function is to discharge the gas generated in the reaction inside the synthesis tower 2. One end of the exhaust pipe 1 is fixedly connected to the synthesis tower 2. It is the channel for the gas inside the synthesis tower to be discharged, and the treated gas is transported to the subsequent treatment equipment or discharged into the atmosphere.

[0032] Synthesis Tower 2: The core part of the entire equipment. It is cylindrical in shape and is the place where the synthesis reaction takes place. The internal reaction will generate heat and produce various gaseous and liquid products. Other components are set on its top, currently labeled 3, which is not specified. They may be some control devices or interfaces. Holes are opened on one side of the exterior for connecting other components to realize the various functions of the synthesis tower.

[0033] Mainstream pipe 4: Mainstream pipe 4 is connected to the top of synthesis tower 2. It is the main channel for liquid transmission. On the one hand, mainstream pipe 4 provides liquid to the first spray ring 5, so that the nozzle 6 at the bottom of the first spray ring 5 can spray the liquid evenly into the synthesis tower 2. On the other hand, the bottom of mainstream pipe 4 is connected to water pump 16 in water tank 17 to realize the circulation supply of liquid.

[0034] First spray ring 5 and nozzle 6: The first spray ring 5 is annular cylindrical in shape and is fixedly connected to one end of the outside of the synthesis tower 2. Multiple nozzles 6 are fixedly connected to its bottom. The liquid delivered by the main pipe 4 is evenly sprayed into the synthesis tower 2 by the nozzles 6, which plays a role in cooling, assisting in filtration and adsorption of the gas or liquid in the tower.

[0035] Filter layer 7: Fixedly connected inside the synthesis tower 2, filter layer 7 is equipped with a filter element. When the gas or liquid in the synthesis tower 2 passes through the filter layer 7, the filter element can intercept and filter the solid impurities in it, perform preliminary purification of the gas or liquid, and reduce the processing burden of the subsequent adsorption layer 10.

[0036] Second spray ring 8 and nozzle 2 9: The outer part of the second spray ring 8 is also set as an annular cylinder, which is fixedly connected to the main flow pipe 4. Multiple nozzles 2 9 are also fixedly connected to its bottom, which cooperate with the first spray ring 5 and nozzle 1 6 to further spray the gas or liquid in the synthesis tower 2 evenly, so that the cooling, filtration and adsorption processes are more complete.

[0037] Adsorption layer 10: Fixedly connected inside the synthesis tower 2, with activated carbon particles of different sizes on the top. After the gas or liquid is initially filtered by the filter layer 7, it reaches the adsorption layer 10. The activated carbon particles use their porous structure and adsorption properties to adsorb harmful components, odors and other substances in the gas or liquid, achieving deep purification. A hole is opened on the outer side of the adsorption layer 10, and a funnel 13 is fixedly connected to the bottom of the hole to guide the liquid to flow downward.

[0038] Connecting pipe 11 and heat exchange coil 12: A connecting pipe 11 is fixedly connected to the bottom of the adsorption layer 10, and a heat exchange coil 12 is fixedly connected to the bottom of the connecting pipe 11. The heat exchange coil 12 is plate-shaped on the outside, which increases the contact area with the substance in the tower and improves the heat exchange efficiency. The liquid flowing down from the adsorption layer 10 enters the heat exchange coil 12 through the connecting pipe 11 and absorbs the heat generated by the reaction in the tower in the heat exchange coil 12 to achieve heat exchange.

[0039] Funnel 13 and inlet 14: Funnel 13 is fixedly connected to the bottom of the hole on the outside of the adsorption layer 10 to guide the liquid to flow smoothly into the heat exchange coil 12 below. The top of the inlet 14 is fixedly connected to the bottom of the funnel 13 so that the liquid can flow from the funnel 13 into the heat exchange coil 12, and after heat exchange in the heat exchange coil 12, it flows back to the water tank 17 through the outlet 15.

[0040] Liquid outlet 15, water pump 16 and water tank 17: The outside of liquid outlet 15 penetrates the inside of synthesis tower 2 and is connected to heat exchange coil 12. It is used to draw out the liquid after heat exchange through heat exchange coil 12 from synthesis tower 2. Water tank 17 is fixedly connected to the outside of synthesis tower 2 and water pump 16 is fixedly connected inside. One end of water pump 16 is fixedly connected to liquid outlet 15 and the other end is connected to main flow pipe 4. Water pump 16 draws out the liquid in water tank 17 and delivers it to heat exchange coil 12 through liquid outlet 15 to complete the recycling of liquid. At the same time, it provides liquid to main flow pipe 4 to realize the functions of spraying and heat exchange.

[0041] Instructions for use

[0042] Water pump 16 in water tank 17 draws water from outlet 15, which then enters the heat exchange coil 12 inside synthesis tower 2. The water flows through the heat exchange coil 12, absorbing the heat generated by the reaction inside synthesis tower 2, and then flows back to water tank 17 through inlet 14, completing one cycle. This cycle repeats continuously, cooling synthesis tower 2 and maintaining a stable temperature inside the tower. The gas or liquid inside synthesis tower 2 first passes through filter layer 7, where the filter element initially intercepts and filters solid impurities. The gas or liquid that has passed through this initial filtration continues to flow downwards to adsorption layer 10. The activated carbon particles at the top of the 10 column utilize their porous structure and adsorption properties to adsorb harmful components and odors in the gas or liquid, further purifying the gas or liquid. The main flow pipe 4 at the top of the synthesis tower 2 provides liquid to the first spray ring 5 and the second spray ring 8. The nozzles 6 and 9 at the bottom of the first spray ring 5 and the second spray ring 8 spray the liquid evenly into the synthesis tower 2. The sprayed liquid can reduce the temperature of the gas or liquid in the tower and assist in heat exchange. On the other hand, the sprayed liquid comes into full contact with the gas or liquid during its fall, making the filtration and adsorption process more thorough and improving the purification effect.
