Description

Technical Field

[0001] This utility model relates to the field of gas detection, and in particular to a condensation and separation device for gas detection. Background Technology

[0002] Gas detection is an important technical means with an irreplaceable role in many fields. Its core purpose is to ensure safety, maintain health, promote production optimization, and protect the ecological environment by analyzing the composition, concentration, and characteristics of gases. It is an indispensable technical link in modern society.

[0003] The working principle of condensation separation is based on the phase change characteristics of substances. That is, by lowering the gas temperature or increasing the gas pressure, the component with a higher boiling point reaches a saturated state, changing from a gaseous state to a liquid (or solid) state, thereby separating it from the gaseous component with a lower boiling point. Its core is to utilize the difference in the correlation between the saturated vapor pressure and temperature of different substances to achieve selective phase change separation.

[0004] In gas detection, condensation separation is a key pretreatment technology. Its core function is to reduce the temperature of the gas, causing specific components (especially easily condensable volatile organic compounds, moisture or other high-boiling-point components) to change from a gaseous state to a liquid state and be separated, thereby improving the accuracy, stability and sensitivity of the detection.

[0005] Existing gas detection condensation separation devices mostly inject mixed gas into a cooling device, and condensation is achieved by setting the temperature inside the cooling device. However, since the flow direction of the gas in the condenser remains unchanged, the condensation effect is poor, and when the separated gas is discharged, there is a possibility that the condensed liquid may be sprayed out along with it.

[0006] To this end, we propose a device that can improve the condensation and separation effect of mixed gases and reduce the possibility of condensed liquid being ejected. Utility Model Content

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1, referring to Figures 1 to 5 This embodiment provides a condensation separation device for gas detection, which facilitates improved condensation separation efficiency and reduces the possibility of condensate being carried out.

[0029] Specifically, the gas collection mechanism 1 includes an air inlet 11, which includes an air inlet cylinder 111 and an air inlet pipe 112 fixedly disposed on the side wall of the air inlet cylinder 111 and communicating with its interior. The longitudinal section of the air inlet pipe 112 is an inverted "L" shape. It should be noted that the air inlet cylinder 111 is used to inject the mixed gas to be separated.

[0030] An air outlet 12 is provided on the air inlet 11. The air outlet 12 includes an air outlet 122 which is fixedly disposed on the side wall of the air inlet 111 and communicates with its interior, and an air pump 121 disposed on the air outlet 122. It should be noted that the air outlet 122 is used to discharge gas.

[0031] A condenser cylinder 13 is installed inside the air intake section 11. The condenser cylinder 13 is fixedly installed on the inner side wall of the air intake cylinder 111. The condenser cylinder 13 is connected to the external refrigerant. The lower end of the air intake pipe 112 is located above the condenser cylinder 13. It should be noted that the condenser cylinder 13 is equipped with a temperature control system to regulate the temperature inside the condenser cylinder 13, so as to facilitate temperature regulation for condensation and separation.

[0032] A condensing mechanism 2 is provided inside the air intake cylinder 111. The condensing mechanism 2 includes a guide section 21 provided inside the air intake section 11. The guide section 21 includes a guide plate 211 fixedly provided inside the air intake cylinder 111 and a guide hole 212 provided through the middle of the guide plate 211. The guide plate 211 is funnel-shaped and is located below the condensing cylinder 13. It should be noted that the funnel shape of the guide plate 211 facilitates the downward flow of the condensed liquid.

[0033] An air intake section 11 is provided with a flow guide section 22, which includes a flow guide cavity 221 disposed inside the air intake cylinder 111 and a flow guide pipe 222 disposed inside the flow guide cavity 221. The flow guide cavity 221 is located below the guide plate 211, and the upper end of the flow guide pipe 222 communicates with the interior of the condenser cylinder 13 through a flow guide hole 212. It should be noted that the flow guide pipe 222 is designed to be curved to reduce the possibility of condensed liquid being carried out.

[0034] An exhaust section 23 is provided inside the air intake section 11. The exhaust section 23 includes an exhaust cavity 231 disposed inside the air intake cylinder 111, an exhaust pipe 233 fixedly disposed on the side wall of the exhaust cavity 231 and communicating with its interior, a control pump 232 fixedly disposed on the exhaust pipe 233, and a guide pipe 222 whose lower end passes through the exhaust cavity 231 and communicates with its interior.

[0035] The air intake cylinder 111 is provided with a turbulence mechanism 3. The turbulence mechanism 3 includes a drive unit 31 provided in the air intake section 11. The drive unit 31 includes two fixed plates 311 fixedly provided in the air intake pipe 112 and a fan 312 rotatably provided between the two fixed plates 311.

[0036] It should be noted that the air intake 11 is provided with a turbulence section 32, which includes a rotating rod 321 that passes through and is rotatably mounted on the fixed plate 311, and several turbulence plates 322 that are fixedly mounted on the outer wall of the rotating rod 321. The rotating shaft of the fan 312 is coaxially and fixedly connected to the rotating rod 321.

[0037] In actual use, the control pump 232 is first turned off, and the gas in the air inlet cylinder 111 is evacuated by the air pump 121. Then, the mixed gas is injected into the air inlet pipe 112. The continuous injection of airflow in the air inlet pipe 112 drives the fan 312 to rotate, thereby rotating the rotating rod 321 and the turbulence plate 322. This makes the air temperature distribution in the condenser cylinder 13 more uniform and improves the efficiency of condensation and separation of the mixed gas. Due to the funnel-shaped setting of the guide plate 211 and the curved setting of the guide pipe 222, the condensed liquid enters the exhaust chamber 231 and is discharged through the guide plate 211 and the guide pipe 222, reducing the possibility of condensate being carried out during exhaust.
