[0039] The present invention provides the following embodiments.

[0040] Example 1

[0041] This invention provides a surround-type capillary condenser device, as shown in Figures 1 and 2, comprising: a gas inlet tank 1, which is a vertical cylindrical structure and is stably supported by a support frame 7; a liquid inlet pipe 2 is provided at the top of the gas inlet tank 1 for introducing condenser, and an air inlet pipe 3 is provided on the upper side of the gas inlet tank 1 for introducing sample gas (such as hot gas to be condensed); an air outlet pipe 4 and a condensate pipe 6 are provided on the lower side of the gas inlet tank 1, and a liquid outlet pipe 5 and a support frame 7 are provided at the bottom of the gas inlet tank 1; a partition plate 11 is horizontally fixed inside the gas inlet tank 1, dividing the interior of the gas inlet tank 1 into an upper stirring chamber 12 and a lower condensation chamber 13 by the horizontally welded partition plate 11; a stirring assembly is provided in the stirring chamber 12, and a condensation assembly is provided in the condensation chamber 13.

[0042] The tank is divided into a stirring chamber 12 and a condensation chamber 13 by the isolation plate 11, realizing two stages: pre-cooling of the refrigerant and deep condensation of the gas. The refrigerant is stirred in the stirring chamber, and the temperature is uniform, which prepares for subsequent condensation.

[0043] The working principle and beneficial effects of the above technical solution are as follows: the support frame 7 provides stable support for the gas tank 1, the inner wall of the gas tank 1 is fixedly connected to the isolation plate 11, the isolation plate 11 isolates and seals the stirring chamber 12 and the condensing chamber 13, the sample gas is added into the condensing chamber 13 in the gas tank 1 through the inlet pipe 3, and various condensing agents are added into the stirring chamber 12 in the gas tank 1 through the liquid inlet pipe 2 for stirring evenly. The evenly stirred condensing agent enters the condensing chamber 13 to condense and cool the sample gas added at the same time, thereby facilitating the subsequent analysis of the sample gas. The condensed and heated condensing agent is discharged from the liquid outlet pipe 5 for the next step of processing, and the cooled sample gas is discharged from the gas outlet pipe 4 for the next step of processing. The liquid droplets condensed by the sample gas in the condensing chamber 13 due to cooling are collected and discharged from the condensate pipe 6 for the next step of processing. This condensation device has a simple structure, high condensation efficiency, high space utilization, and low maintenance cost.

[0044] Example 2

[0045] Based on Embodiment 1, as shown in Figures 1-2, the stirring assembly includes a motor 141, which is fixedly mounted on the top of the gas tank 1. The drive end of the motor 141 is connected to a drive shaft 142 via a coupling. The drive shaft 142 extends into the stirring chamber 12, and a spiral blade 143 is fixedly mounted on the drive shaft 142.

[0046] The working principle and beneficial effects of the above technical solution are as follows: the gas tank 1 supports and fixes the motor 141, the motor 141 drives the drive shaft 142 to rotate through the coupling, the drive shaft 142 drives the spiral blade 143 to rotate in the stirring chamber 12, and mixes the various condensers added to the stirring chamber 12 evenly, thereby improving the condensation efficiency of the condenser.

[0047] Multiple evenly spaced spiral blades 143 are fixedly welded to the drive shaft 142. When the motor 141 starts, it drives the spiral blades 143 to rotate. On the one hand, it strongly stirs the condensate entering from the liquid inlet pipe 2, making its temperature quickly and evenly. On the other hand, the rotation of the spiral blades 143 will generate a downward pumping effect, pushing the condensate to the isolation plate 11.

[0048] Example 3

[0049] Based on Embodiment 2, as shown in Figures 1-2, the condensation assembly includes multiple liquid passage pipes 151, and the isolation plate 11 is provided with multiple (e.g., 4) liquid outlets 152. The multiple vertical liquid passage pipes 151 are connected one-to-one with the multiple liquid outlets 152 on the isolation plate 11. Each liquid outlet 152 is equipped with an automatic liquid outlet valve 153 (e.g., a solenoid valve). When the liquid level in the stirring chamber 12 reaches a certain height, the automatic liquid outlet valve 153 opens, and the refrigerant flows into the condenser. Condensation chamber 13; the number of liquid passage pipes 151 and liquid outlets 152 are the same, the top of the liquid passage pipes 151 is connected to the bottom of the liquid outlets 152, and the bottom of the liquid passage pipes 151 is provided with a spiral condenser tube 154 coiled in a spiral shape. Multiple spiral condenser tubes 154 are of the same height and arranged in a ring. In this embodiment, there are 4 spiral condenser tubes 154, which are arranged in a centrally symmetrical ring on the same horizontal plane, thereby forming a central channel for gas to rise in the middle of the gas tank 1. A fixing sleeve 155 is provided on the outer ring of each spiral condenser tube 154. The fixing sleeve 155 is welded to the inner wall of the gas tank 1 by fixing post 156. The fixing sleeve 155 has a semi-circular structure, and its inner wall is embedded with an elastic gasket made of high temperature resistant rubber, thereby tightening and fixing the spiral condenser tube 154, which not only ensures the firmness of the fixation, but also avoids damage to the tube wall. A connecting seat with an internal thread is welded to the outside of the fixing sleeve 155. One end of the fixing post 156 is machined with an external thread and screwed into the connecting seat. The connection with the fixing sleeve 155 is achieved by locking the nut to prevent loosening. The other end of the fixing post 156 is fixed to the inner wall of the gas tank 1 by welding, thereby providing stable support for the entire condensation assembly.

[0050] The condensing chamber 13 uses multiple spiral condensing tubes 154 arranged in a ring as condensing units, which greatly increases the contact area and contact time between the refrigerant and the rising hot gas sample, thereby significantly improving the condensing efficiency.

[0051] Each spiral condenser tube 154 has a liquid-passing pipe 157 at its bottom outlet. Multiple liquid-passing pipes 157 are fixedly inserted into a guide plate 158. One end of the guide plate 158 is fixedly mounted (by welding or a bolt and nut assembly) on the inner wall of the gas tank 1, and the other end of the guide plate 158 is connected to the liquid outlet pipe 5. The guide plate 158 is inclined at a certain angle (e.g., 45°-60°) to allow the refrigerant to be discharged through the liquid outlet pipe 5, enabling it to be recycled and reused.

[0052] While stirring, the spiral blades 143 in the stirring chamber exert a downward thrust on the condensate, working in conjunction with the automatic liquid outlet valve 153 of the liquid outlet 152 to effectively prevent the liquid outlet from being blocked by impurities. At the same time, the gas passage (condensing chamber) and the liquid passage (inside the spiral condenser tube) are completely isolated, fundamentally avoiding the problem of condensate blocking the gas passage.

[0053] The working principle and beneficial effects of the above technical solution are as follows: the liquid outlet 152 fixes and limits the automatic liquid outlet valve 153. When the condensate is stirred in the stirring chamber 12 for a set time, the automatic liquid outlet valve 153 opens, and the stirred condensate is transported from the stirring chamber 12 through multiple liquid outlets 152 along the liquid passage pipe one 151, the spiral condenser pipe 154, and the liquid passage pipe two 157. The design combination of multiple spiral condenser pipes 154 in a ring shape makes the sample gas cooling time longer and accelerates the cooling speed of the sample gas. The fixed sleeve 15 5. The spiral condenser tube 154 is fixed, and the fixing column 156 fixes the fixing sleeve 155, so that the spiral condenser tube 154 is stably fixed on the inner wall of the gas tank 1, preventing the spiral condenser tube 154 from falling and being damaged under gravity for a long time. During the transmission process, the refrigerant absorbs heat and cools the sample gas in the condensation chamber 13. When the sample gas temperature decreases, the water vapor in it condenses into water droplets and falls onto the guide plate 158 below. Under the action of gravity, it flows along the guide plate 158 into the liquid outlet pipe 5 and is discharged and collected for treatment.

[0054] Example 4

[0055] Based on Embodiment 1, as shown in Figures 1-2, a fan 41 is fixedly installed inside the air outlet pipe 4 by a fixing plate (using a bolt and nut assembly fixing method), and a molecular sieve plate 42 is inserted into the air outlet pipe 4.

[0056] The fan 41 accelerates gas flow, promotes gas contact with the condenser tube, and improves condensation efficiency. The molecular sieve plate 42 filters impurities in the gas, ensuring the purity of the discharged gas. The condensed liquid droplets fall directly to the bottom of the tank and are discharged through the liquid outlet pipe 5; while the uncondensed waste gas is drawn out through the side outlet pipe 4 by the fan 41 and dried and purified through the molecular sieve plate 42, achieving fine separation and purification of gas and liquid.

[0057] The working principle and beneficial effects of the above technical solution are as follows: the exhaust pipe 4 fixes the fan 41, and the molecular sieve plate 42 is inserted into the exhaust pipe 4, which facilitates the replacement of the molecular sieve plate 42 after a period of use. The fan 41 generates suction to draw out the sample gas that has been condensed in the condensation chamber 13. When the sample gas passes through the molecular sieve plate 42, the molecular sieve plate 42 adsorbs the residual water vapor in the sample gas, thus removing the moisture in the sample gas more thoroughly.

[0058] Example 5

[0059] Based on Example 3, as shown in Figures 1-2, the spiral condenser tube 154 is made of high-temperature resistant plastic, and the fixing sleeve 155 and the fixing column 156 are both made of aluminum alloy.

[0060] The working principle and beneficial effects of the above technical solution are as follows: The spiral condenser made of high-temperature resistant plastic material has good impact resistance and is not easy to break or damage. Even if it is accidentally dropped or collided, it can maintain good integrity. The high-temperature resistant plastic condenser tube can maintain stable performance at high temperatures and is not easy to deform or melt. It is suitable for condensation operations in high-temperature environments. Although glass condenser tubes can also withstand certain high temperatures, they may break or explode under extreme high temperatures. The fixing sleeve 155 and fixing post 156 made of aluminum alloy material will form a dense aluminum oxide film on its surface when aluminum reacts with oxygen. This film is very hard and corrosion resistant and can effectively prevent further oxidation of aluminum, thus playing a role in rust prevention while fixing the spiral condenser tube 154.
