Description

Technical Field

[0001] This application relates to the field of waste gas treatment equipment technology, and in particular to a tail gas condenser. Background Technology

[0002] Currently, the production and processing of API raw materials and chemical industries (including fine chemical industry) generate mixed industrial exhaust gases containing VOCs. If these VOC industrial exhaust gases are directly emitted, they will pollute the atmosphere and damage the ecological environment.

[0003] When treating these VOCs industrial exhaust gases, the condensation recovery method is usually adopted. This method involves heat exchange and condensation of the VOCs industrial exhaust gases through a condenser, causing the condensable organic waste gases contained in these VOCs industrial exhaust gases to condense into organic liquids. This not only removes the organic waste gases from the VOCs industrial exhaust gases, but also allows for the collection and recovery of the condensed organic liquids, which has good economic and environmental value.

[0004] When treating the aforementioned VOCs industrial exhaust gas, because the VOCs industrial exhaust gas contains small solid particles such as dust, it is easy to adhere to the heat exchange tubes. As heat exchange proceeds, the accumulation reaches a certain level, which will affect the heat exchange efficiency of the heat exchange tubes, thereby reducing the treatment efficiency of VOCs industrial exhaust gas. Summary of the Invention

[0005] To address the aforementioned problems, this application provides an exhaust gas condenser.

[0006] This application provides a tail gas condenser, comprising a heat exchange cylinder, a first partition, a second partition, and a heat exchange tube; the first partition and the second partition are both fixedly disposed inside the heat exchange cylinder, dividing the interior of the heat exchange cylinder into a first cavity, a second cavity, and a third cavity; an adsorption mechanism is disposed inside the first cavity; an inlet pipe and an outlet pipe are connected to the heat exchange cylinder, the inlet pipe being connected to the first cavity and the outlet pipe being connected to the third cavity; a first through hole is formed on the first partition, with both ends of the first through hole connected to the first cavity and the second cavity respectively; a second through hole is formed on the second partition, with both ends of the second through hole connected to the second cavity and the third cavity respectively; the heat exchange tube is located inside the second cavity, and both ends are fixedly connected to the first partition and the second partition respectively; an inlet pipe and an outlet pipe are disposed on the heat exchange cylinder, both of which are connected to the heat exchange tube.

[0007] By adopting the above technical solutions, the exhaust gas condenser can achieve efficient heat exchange and waste gas treatment. Specifically, the multi-chamber structure within the heat exchange cylinder, combined with the design of the heat exchange tubes, effectively extends the flow path of the exhaust gas within the equipment, increasing the contact time between the exhaust gas and the cooling medium, thereby significantly improving condensation efficiency. Simultaneously, the adsorption mechanism within the first chamber can pre-treat particulate matter and harmful components in the exhaust gas, further enhancing the exhaust gas purification effect and providing a cleaner gas environment for the subsequent condensation process. Furthermore, the rational layout design of the inlet and outlet pipes helps to form a stable airflow direction, reducing eddies and pressure loss, and ensuring the operational stability and energy efficiency of the entire system.

[0008] Preferably, the adsorption mechanism includes two sets of air guide components, which are disposed on the inner wall of the heat exchange cylinder. A filter component is disposed between the two sets of air guide components, which is also disposed on the inner wall of the heat exchange cylinder. A spray component is disposed above the filter component, which is disposed between the two sets of air guide components and on the inner wall of the heat exchange cylinder. A cleaning component is connected to the spray component for cleaning the filter component.

[0009] By adopting the above technical solutions, the air guiding component can effectively guide the exhaust gas flow, making the exhaust gas distribution more uniform within the first chamber, thereby improving the contact efficiency between the exhaust gas and the adsorption mechanism. The filter component can intercept and filter particulate matter in the exhaust gas, further enhancing the exhaust gas purification effect. The spray component, by spraying liquid, can not only capture tiny particles in the exhaust gas but also reduce the exhaust gas temperature, providing favorable conditions for the subsequent condensation process. The cleaning component regularly removes deposits from the filter component, ensuring its continuous and efficient operation and extending the equipment's service life.

[0010] Preferably, the air guide assembly includes an air guide frame disposed on the inner wall of the heat exchange cylinder, an air guide ring disposed on the air guide frame, a plurality of outer air guide blades disposed on the side of the air guide ring facing the inner wall of the heat exchange cylinder, and a plurality of inner air guide blades disposed on the side of the air guide ring away from the inner wall of the heat exchange cylinder.

[0011] By adopting the above technical solution, the air guide assembly can effectively guide the flow direction of the exhaust gas within the heat exchange cylinder. Specifically, the air guide ring on the air guide frame, in conjunction with the outer and inner air guide blades, creates a spiral airflow within the first chamber, thereby improving the contact efficiency between the exhaust gas and the adsorption mechanism and enhancing the adsorption effect. Simultaneously, the design of the inner air guide blades helps the exhaust gas enter the second chamber more evenly, providing a good flow field distribution for the subsequent heat exchange process.

[0012] Preferably, the filtration assembly includes a first filter plate and a second filter plate disposed on the inner wall of the heat exchange cylinder, and a filtration chamber is formed between the first filter plate and the second filter plate.

[0013] By adopting the above technical solution, the exhaust gas condenser is equipped with a filter assembly consisting of a first filter plate and a second filter plate in the first chamber. The filter chamber formed between the two plates can effectively intercept and filter impurity particles in the exhaust gas, improving the cleanliness of the exhaust gas treatment. This structure is simple and reliable, providing a purer gas environment for the subsequent condensation process, thereby improving the overall condensation efficiency and equipment lifespan.

[0014] Preferably, a material exchange port is provided on the side wall of the filter chamber, and a material exchange door is provided at the opening of the material exchange port. One end of the material exchange door is hinged to the heat exchange cylinder. A first magnetic strip is provided on the material exchange door, and a second magnetic strip is provided on the heat exchange cylinder. The first magnetic strip and the second magnetic strip can attract each other.

[0015] Preferably, the spray assembly is disposed inside the heat exchange cylinder. The spray assembly includes an expansion chamber disposed outside the heat exchange cylinder, a rotating motor disposed inside the expansion chamber, a rotating shaft coaxially connected to the transmission end of the rotating motor, the rotating shaft being vertically disposed, a drive gear coaxially disposed on the rotating shaft, the drive gear meshing with a rotating gear ring, the rotating gear ring being disposed inside the heat exchange cylinder, a rotating groove being disposed on the bottom surface of the rotating gear ring, a spray pipe being disposed on the rotating gear ring, a plurality of spray nozzles being disposed on the spray pipe, a plurality of liquid inlets being disposed above the spray pipe, an adsorbent tube being connected to the liquid inlet, the adsorbent tube extending to the outside of the heat exchange cylinder, and a connecting rod disposed on the inner wall of the heat exchange cylinder, a contour block being disposed on the connecting rod, the contour block being slidably connected in the rotating groove.

[0016] By adopting the above technical solution, the spray assembly can achieve uniform spraying of the filter assembly, effectively improving the settling efficiency of particulate matter in the exhaust gas. A rotating motor drives the rotating shaft and drive gear to rotate, causing the rotating gear ring to rotate within the heat exchange cylinder, thus ensuring that the spray nozzles on the spray pipe fully cover the filter chamber area. Simultaneously, the adsorbent tube continuously supplies liquid to the spray pipe, ensuring the stability and continuity of the spraying process. This design enhances the exhaust gas purification effect. Preferably, the cleaning assembly includes at least two connecting pipes disposed on the spray pipe, the connecting pipes being connected to a cleaning pipe, the cleaning pipe passing through the filter assembly, the cleaning pipe being provided with a cleaning valve, the cleaning pipe being connected to two sets of cleaning chambers, the cleaning chambers being provided with a plurality of cleaning bristles on the side facing the filter assembly, and the cleaning chambers being provided with a plurality of cleaning holes on the side facing the filter assembly.

[0017] By adopting the above technical solution, the cleaning bristles on the cleaning tube can physically clean the filter components, effectively removing impurities adhering to their surface; the cleaning holes can spray cleaning fluid to further dissolve and flush the dirt on the filter components, ensuring the stability of the filtration effect. The design of the connecting tube and the cleaning tube makes the cleaning process more comprehensive, and the setting of the cleaning valve makes it easy to control the flow rate of the cleaning fluid, improving cleaning efficiency.

[0018] Preferably, a condensation chamber is formed inside the side wall of the heat exchange cylinder, and both the liquid inlet pipe and the liquid outlet pipe are connected to the condensation chamber; a first connecting chamber is formed inside the first partition plate; a first connecting pipe is provided on the first partition plate, and the two ends of the first connecting pipe are respectively connected to the first connecting chamber and the condensation chamber; a second connecting chamber is formed inside the second partition plate; a second connecting pipe is provided on the second partition plate, and the two ends of the second connecting pipe are respectively connected to the second connecting chamber and the condensation chamber; a plurality of heat exchange tubes are provided, and the two ends of each heat exchange tube are respectively connected to the first connecting chamber and the second connecting chamber.

[0019] By adopting the above technical solution, the connection between the condensation chamber and the inlet and outlet pipes enables the circulation of coolant, effectively improving heat exchange efficiency. The first and second connecting cavities inside the first and second partitions, along with the first and second connecting pipes connected at both ends to the corresponding connecting cavities and the condensation chamber respectively, ensure uniform distribution of coolant within the heat exchange tubes, further enhancing the heat exchange effect. The design of several heat exchange tubes connected at both ends to the first and second connecting cavities increases the heat exchange area, significantly enhancing the overall heat exchange performance of the exhaust gas condenser.

[0020] Preferably, the heat exchange cylinder is vertically arranged; the connection between the liquid inlet pipe and the condensation chamber is located at the bottom of the heat exchange cylinder; and the connection between the liquid outlet pipe and the condensation chamber is located at the top of the heat exchange cylinder.

[0021] By adopting the above technical solution, the vertical arrangement of the heat exchange cylinder allows the condensate to flow from bottom to top. Combined with the design that the inlet pipe and the condensation chamber are connected at the bottom of the heat exchange cylinder and the outlet pipe and the condensation chamber are connected at the top, the flow of condensate can be effectively promoted by gravity, thereby improving condensation efficiency and reducing power consumption.

[0022] Preferably, the connection between the air inlet pipe and the first cavity is located at the top of the heat exchange cylinder; the connection between the exhaust pipe and the third cavity is located at the bottom of the heat exchange cylinder; the exhaust pipe is disposed at the bottom of the heat exchange cylinder, the exhaust pipe has an L-shaped structure, and an air pump is installed on the exhaust pipe; a recovery pipe is vertically disposed at the bottom of the exhaust pipe, and the top of the recovery pipe is connected to the exhaust pipe.

[0023] By adopting the above technical solution, the connection between the exhaust gas condenser's inlet pipe and the first chamber is located at the top of the heat exchange cylinder, allowing the exhaust gas to flow from top to bottom. This helps to prolong the residence time of the exhaust gas in the condenser and improve the condensation effect. The connection between the exhaust pipe and the third chamber is located at the bottom of the heat exchange cylinder, facilitating the collection and discharge of the condensed liquid. The exhaust pipe adopts an L-shaped structure and is equipped with an air pump, which can effectively control the exhaust gas emission speed and direction, ensuring that the exhaust gas is fully condensed. In addition, a vertically installed recovery pipe at the bottom of the exhaust pipe is connected to the exhaust pipe, which can further collect the condensed liquid, avoid secondary pollution, and improve the environmental performance of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a first and second baffle plate inside the heat exchange cylinder, the cylinder is cleverly divided into three independent chambers. Combined with the synergistic effect of the heat exchange tubes and the condensation chamber, multi-stage cooling and efficient heat exchange of the gas are achieved. This design not only significantly improves condensation efficiency but also effectively solves the problem of poor condensation performance caused by a single heat exchange structure in traditional condensers. Furthermore, by optimizing the flow path of the condensate, which sequentially passes through the condensation chamber, the first connecting chamber, and the second connecting chamber, the uniformity of heat exchange is further improved, ensuring the complete condensation of pollutants in the exhaust gas. 2. An adsorption mechanism is introduced into the first chamber, guiding the airflow direction through the air guide assembly, and utilizing the filter assembly to efficiently intercept and adsorb particulate matter and other impurities in the exhaust gas, thereby preventing impurity deposition from interfering with the condensation process. Simultaneously, the addition of a spray assembly further captures fine particulate matter by spraying liquid, enhancing the purification effect. Furthermore, the design of the cleaning assembly allows for regular removal of deposits from the filter assembly surface, extending its service life and reducing equipment maintenance frequency and costs. 3. The gas flow path is meticulously designed. The rational layout of the first and second through holes ensures that the gas flows along a predetermined trajectory within the heat exchange cylinder, preventing short-circuiting. Simultaneously, the orderly transition of gas between multiple chambers extends its residence time. Combined with the efficient heat exchange function of the condenser chamber and heat exchange tubes, harmful substances in the exhaust gas can be fully condensed into liquid, significantly improving the overall performance and reliability of the condenser.

A recovery pipe 4 is vertically positioned at the bottom of the exhaust pipe 108, and the top of the recovery pipe 4 is connected to the exhaust pipe 108.

[0038] The implementation principle of a tail gas condenser in this application embodiment is as follows: When treating VOCs industrial exhaust gas, the operator connects the inlet pipe 111 and the outlet pipe 112 to the chiller. The chiller is started, and coolant is delivered into the condensing chamber 305 through the inlet pipe 111. The coolant entering the condensing chamber 305 will enter the second connecting chamber 303 through the second connecting pipe 304 under its own gravity. Then, it will gradually fill the second connecting chamber 303, and then fill the heat exchange tube 103 and the condensing chamber 305. Then, it will flow into the first connecting chamber 301 through the first connecting pipe 302, filling the first connecting chamber 301. Finally, it will flow back to the chiller through the outlet pipe 112, forming a cycle. During the process of filling the heat exchange tube 103 and the condensing chamber 305, the liquid level in the heat exchange tube 103 and the liquid level in the condensing chamber 305 are at the same height.

[0039] After the coolant fills the condensing chamber 305, the first connecting chamber 301, the second connecting chamber 303, and the heat exchange tube 103, the operator delivers the VOCs industrial exhaust gas into the first chamber 104 through the inlet pipe 107. As the VOCs industrial exhaust gas flows within the first chamber 104, the small solid particles it carries are adsorbed and removed by the activated carbon within the first chamber 104. The remaining VOCs industrial exhaust gas then enters the second chamber 105 through the first through hole 109. Under the action of the guide plate, the VOCs industrial exhaust gas flows along an S-shaped airflow channel within the second chamber 105. During this flow, it exchanges heat with the coolant in the heat exchange tube 103, the first connecting chamber 301, the second connecting chamber 303, and the condensing chamber 305. The condensable organic waste gas contained in the VOCs industrial exhaust gas releases heat and condenses to form an organic liquid, which flows into the third chamber 106 through the second through hole 110 and is finally discharged through the exhaust pipe 108 and the recovery pipe 4 for collection and recovery by the operator. The remaining VOCs industrial exhaust gas flows into the third chamber 106 through the second through hole 110, and is finally discharged through the exhaust pipe 108 under the action of the air pump. The operator collects the remaining VOCs industrial exhaust gas for subsequent treatment.

[0040] After a certain period of use, the operator first stops inputting VOCs industrial exhaust gas, then opens the material replacement door 2025 by the handle, and then replaces the activated carbon packing in the filter chamber 2023 through the material replacement port 2024. After replacement, the material replacement door 2025 is closed. Under the magnetic force of the first magnetic strip 2026 and the second magnetic strip 2027, the material replacement door 2025 is fixed to the heat exchange cylinder 1. After the packing is replaced, VOCs industrial exhaust gas can be treated again.
