[0002] A solvent recovery condenser is a device used for solvent recovery. Its working principle is to cool and condense the waste gas containing solvent in the condenser, changing the solvent from a gaseous state to a liquid state and collecting and recovering it.

The tower body is provided with a steam inlet, a gas outlet and a recovery liquid outlet, and the tower body is divided into multiple refrigeration zones by a partition. Each of the multiple refrigeration zones is provided with a copper inner sleeve. The advantages of this utility model are: based on the property that organic solvents have different saturated vapor pressures at different temperatures, by cooling or pressurizing, the partial pressure of the organic components in the waste gas is made equal to the saturated vapor pressure at that temperature, so that the organic components are condensed into liquid and separated from the gas phase. Different recovery temperatures are designed and selected for different gases, so as to maximize the solution of waste gas emissions and the recovery of valuable solvents, thereby achieving the purpose of saving costs and meeting environmental protection standards.
[0004] In existing technologies, it is inconvenient to repeatedly circulate the cooling medium during the use of condensing towers, which indirectly increases the operating cost of condensing towers. Furthermore, the odor in the exhaust gas during the exhaust process of condensing towers can easily pollute the external environment. Therefore, improvements are needed. Utility Model Content

A filter plate is slidably fitted inside the water tank. A pull rod is fixedly connected to the top of the filter plate, and a support block contacts the bottom of the filter plate. The support block is fixedly connected to the water tank. By designing this circulation mechanism, the cooling water can be circulated.
[0008] Preferably, the return pipe is fixedly connected to the tower body and the water tank. By designing the return pipe, cooling water can be returned to the inside of the water tank.
[0009] Preferably, a positioning block is slidably fitted inside the support block, and the positioning block is fixedly connected to the filter plate. The positioning block allows for the support and positioning of the filter plate.
[0010] Preferably, the purification mechanism includes a baffle, which is slidably fitted inside the exhaust port. A handle is fixedly connected to the right end of the baffle, and a connecting rod is fixedly connected to the left end of the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model utilizes the design of a condenser tube. Cooling water flows inside the condenser tube, and gas containing solvent vapor enters from the inlet pipe and comes into contact with the condenser tube. Since the temperature of the cooling water is lower than the dew point temperature of the solvent vapor, the solvent vapor transfers heat to the circulating water, lowers its own temperature, and gradually condenses into a liquid. The solvent can then be recovered through a storage tank. The condensation process relies on circulating cooling water, which greatly reduces water consumption and energy costs compared to disposable cooling media. Furthermore, the cooling water can be cooled by refrigeration plates to improve the condensation effect. The removable filter plate can filter and purify the cooling water, preventing impurities from entering the pipeline and causing blockages due to inconvenient cleaning.
[0015] 2. This utility model, through the design of the exhaust port, can be used to discharge gas inside the tower. During the gas discharge process, the gas can be filtered and purified by the filter element to prevent odor from polluting the external environment after the gas is discharged. At the same time, the filter element can be easily pulled out from inside the exhaust port for easy replacement. Attached Figure Description

The water pump 81 has an inlet 82 at its left end and a drain pipe 83 at its right end. The drain pipe 83 is fixedly connected to both the water tank 1 and the tower body 3, and is also fixedly connected to a condenser pipe 7. A return pipe 84 is fixedly connected to the left end of the condenser pipe 7, and is fixedly connected to both the tower body 3 and the water tank 1. By designing the return pipe 84, cooling water can be returned to the water tank 1. Inside, multiple cooling plates 85 are fixedly installed on the bottom of the inner wall of the water tank 1. A filter plate 86 is slidably sleeved inside the water tank 1. A pull rod 87 is fixedly connected to the top of the filter plate 86. A support block 88 is in contact with the bottom of the filter plate 86. The support block 88 is fixedly connected to the water tank 1. A positioning block 89 is slidably sleeved inside the support block 88. The positioning block 89 is fixedly connected to the filter plate 86. The positioning block 89 can support and position the filter plate 86. The circulation mechanism 8 can be designed to realize the circulation of cooling water.
[0024] Please see Figure 1 , Figure 2 , Figure 4The purification mechanism 9 includes a baffle 91. The baffle 91 is slidably fitted inside the exhaust port 10. A handle 92 is fixedly connected to the right end of the baffle 91, and a connecting rod 93 is fixedly connected to the left end of the baffle 91. A connecting plate 94 is fixedly connected to the left end of the connecting rod 93. The connecting plate 94 is slidably connected to the exhaust port 10. Multiple through holes 95 are evenly distributed inside the connecting plate 94, allowing gas to flow through them. The right end of the connecting plate 94 is connected to... The filter element 96 is slidably connected to the exhaust port 10, and is in contact with the baffle 91 and the connecting rod 93. The left end of the connecting plate 94 is fixedly connected to the connecting rod 97, which is slidably connected to the exhaust port 10.

By designing the spring 98, the force of the spring 98 can be applied to the connecting rod 97. By designing the purification mechanism 9, the exhaust gas can be filtered and purified.
[0025] The specific implementation process of this utility model is as follows: During use, the water pump 81 operates, drawing water from the inside of the water tank 1 through the inlet 82, thus inputting cooling water into the drain pipe 83. The cooling water flows inside the condenser pipe 7. Simultaneously, gas containing solvent vapor enters from the inlet pipe 5, and then is transported to the outside through the guide shroud 6. The gas comes into contact with the condenser pipe 7. Since the temperature of the cooling water is lower than the dew point temperature of the solvent vapor, the solvent vapor transfers heat to the circulating water, lowers its own temperature, and gradually condenses into liquid. The solvent can then be recovered through the storage tank 4. The water inside the condenser pipe 7 flows back to the water tank through the return pipe 84. The internal input allows for the recycling of cooling water, significantly reducing water consumption and energy costs compared to disposable cooling media. Combined with the cooling plate 85, it can cool the cooling water to improve condensation. When the cooling water flows back into the water tank 1, the filter plate 86 filters and removes impurities, leaving them on the surface of the filter plate 86 while the water flows through it. This prevents impurities from entering the pipes and causing blockages. The filter plate 86 can be easily removed from the water tank 1 by pulling the lever 87 upwards, facilitating cleaning and maintenance and preventing blockages that could affect water flow.
[0026] The exhaust port 10 can be used to discharge the gas inside the tower body 3. During the gas discharge process, the filter element 96 can filter and purify the gas to prevent odor from polluting the external environment after the gas is discharged. When the handle 92 is pulled outward, the handle 92 can drive the baffle 91 to move. The baffle 91 drives the connecting plate 94 to move. The connecting plate 94 will drive the connecting rod 97 to move. The connecting rod 97 will slide along the exhaust port 10 and squeeze the spring 98, which can bring the filter element 96 out from the inside of the exhaust port 10. Then the filter element 96 can be taken out for easy replacement.
