Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas condensation devices, specifically a gas condensation device for oil chromatography analysis. Background Technology
[0002] In oil chromatography, gas condensation devices are mainly used to cool and collect the gas flowing out of the chromatographic column for subsequent analysis or detection. Gas condensation devices are crucial in oil chromatography, improving the accuracy and sensitivity of the analysis by cooling and collecting the gas. When using them, attention should be paid to the selection of cooling medium, temperature control, and system sealing.
[0003] The existing gas condensation device for oil chromatography has poor sealing at the connection with the gas pipeline, lacking a reliable gas sealing mechanism. This makes it easy for gas entering the gas condensation device to leak through the pipeline connection. Furthermore, the existing gas condensation device for oil chromatography uses a long pipeline with good thermal conductivity to liquefy the gas and collect it on the inner wall of the pipeline during cooling. However, this cooling method is easily affected by the ambient temperature and the cooling effect is not good. Therefore, a new technical solution needs to be designed to solve this problem.

Detailed Implementation
[0021] 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.
[0022] Example 1: Please refer to again Figure 1-5 This utility model provides a gas condensation device for oil chromatography analysis, including a cooling chamber 100. A spiral pipe 110 is fixedly connected between the left and right side walls of the inner cavity of the cooling chamber 100. Both ends of the spiral pipe 110 penetrate the cooling chamber 100 and extend to the left and right side walls of the cooling chamber 100. A sealing mechanism is provided on the left side of the spiral pipe 110. The sealing mechanism includes a sealing tube 120. A sealing groove 121 is opened at the left end of the sealing tube 120. A sealing ring 122 is fixedly connected to the right side wall of the inner cavity of the sealing groove 121. A connecting pipe is inserted into the left end of the sealing tube 120. 130. A sealing ring 131 is fixedly connected to the right end of the connecting pipe 130. The sealing ring 131 is inserted into the sealing ring 122. An extension protrusion ring 140 is integrally formed on the inner side wall of the sealing pipe 120. A sealing ring 150 is fixedly connected to the inner side wall of the connecting pipe 130. The right side wall of the sealing ring 150 extends into the interior of the extension protrusion ring 140. Limiting posts 151 are fixedly connected around the right side wall of the sealing ring 150, and the limiting posts 151 are evenly distributed. The right end of the limiting post 151 passes through the extension protrusion ring 140 and extends to the right side of the extension protrusion ring 140.
[0023] Specifically, by inserting the connecting pipe 130 into the sealing groove 121 of the sealing pipe 120, the sealing retainer 131 on the connecting pipe 130 is tightly connected to the sealing insert ring 122 in the sealing groove 121. The sealing retainer 131 cooperates with the sealing insert ring 122 to form a multi-layer sealing barrier at the connection between the connecting pipe 130 and the sealing pipe 120. At the same time, after the connecting pipe 130 and the sealing pipe 120 are connected in place, the sealing ring 150 installed on the inner side of the connecting pipe 130 is inserted into the inner wall of the extension protrusion ring 140 located on the inner side of the sealing pipe 120. The sealing ring 150 cooperates with the extension protrusion ring 140 to seal the gap at the inner connection between the connecting pipe 130 and the sealing pipe 120. Then, the connecting pipe 130 and the sealing pipe 120 can be connected and fixed by using fixing bolts.
[0024] Example 2: Please refer to again Figure 1-5 A liquid storage tank 200 is fixedly connected to the top of the cooling tank 100. A cooler 210 is fixedly connected to the right side wall of the liquid storage tank 200. A cooling mechanism is provided inside the liquid storage tank 200. The cooling mechanism includes a cooling pipe 220. The cooling pipe 220 is fixedly connected to the left side wall of the cooler 210. The left end of the cooling pipe 220 passes through the liquid storage tank 200 and extends into the inner cavity of the liquid storage tank 200. A return pump 230 is fixedly connected to the left side wall of the liquid storage tank 200. Return pipes 231 are fixedly connected to the front and rear sides of the right side wall of the return pump 230. The right end of the return pipe 231 passes through the liquid storage tank 200 and extends into the inner cavity of the liquid storage tank 200. Liquid delivery pipes 240 are fixedly connected to the front and rear sides of the left side wall of the return pump 230. The ends of the two liquid delivery pipes 240 pass through the cooling tank 100 and extend into the inner cavity of the cooling tank 100.
[0025] Specifically, by starting the refrigerator 210, the cooling pipe 220 is activated, which cools the coolant in the storage tank 200. Then, by starting the return pump 230, the coolant in the storage tank 200 is transported through a return pipe 231 to a delivery pipe 240, and then into the cooling chamber 100. This allows the low-temperature coolant to mix with the room-temperature coolant in the cooling chamber 100, cooling the spiral pipe 110. At the same time, the return pump 230 transports the coolant in the cooling chamber 100 back to the storage tank 200 through the other delivery pipe 241. After being cooled again by the cooling pipe 220, the coolant is transported back to the cooling chamber 100. This cycle continues, keeping the spiral pipe 110 in the low-temperature coolant, thus improving the gas cooling and liquefaction efficiency.
[0026] Working principle: By inserting the connecting pipe 130 into the sealing groove 121 of the sealing pipe 120, the sealing ring 131 on the connecting pipe 130 is tightly connected with the sealing insert ring 122 in the sealing groove 121. The sealing ring 131 cooperates with the sealing insert ring 122 to form a multi-layer sealing barrier at the connection between the connecting pipe 130 and the sealing pipe 120. At the same time, after the connecting pipe 130 and the sealing pipe 120 are connected in place, the sealing ring 150 installed on the inner side of the connecting pipe 130 is inserted into the inner wall of the extension protrusion ring 140 located on the inner side of the sealing pipe 120. The sealing ring 150 cooperates with the extension protrusion ring 140 to seal the gap at the connection between the inner side of the connecting pipe 130 and the sealing pipe 120. Then, the connecting pipe 130 and the sealing pipe 120 can be connected and fixed by using fixing bolts.
[0027] By starting the refrigerator 210, the cooling pipe 220 is activated, which cools the coolant in the storage tank 200. Then, by starting the return pump 230, the coolant in the storage tank 200 is transported through a return pipe 231 to a delivery pipe 240, and then sent into the cooling chamber 100 through the delivery pipe 240. This allows the low-temperature coolant to mix with the room-temperature coolant in the cooling chamber 100, cooling the spiral pipe 110. At the same time, the return pump 230 transports the coolant in the cooling chamber 100 back to the storage tank 200 through the other delivery pipe 241. After being cooled again by the cooling pipe 220, the coolant is transported back to the cooling chamber 100. This cycle is repeated, keeping the spiral pipe 110 in the low-temperature coolant, thus improving the gas cooling and liquefaction efficiency.
