[0039] Example 2

[0040] On the basis of Example 1, Figure 1-Figure 2 As shown, the stirring assembly 14 includes a motor 141, which is fixedly arranged on the top of the gas tank 1. The driving end of the motor 141 is connected to a driving shaft 142 through a coupling. The driving shaft 142 extends into the stirring chamber 12, and a spiral blade 143 is fixedly arranged on the driving shaft 142.

[0041] 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 driving shaft 142 to rotate through the coupling, and the driving shaft 142 drives the spiral blade 143 to rotate in the stirring chamber 12, so that the various condensing agents added to the stirring chamber 12 are evenly mixed, thereby improving the condensation efficiency of the condensing agent.

[0042] Example 3

[0043] On the basis of Example 2, Figure 1-Figure 2As shown, the condensation assembly 15 includes a plurality of liquid passage pipes 151, a plurality of liquid outlets 152 are provided on the isolation plate 11, an automatic liquid outlet valve 153 is provided in the liquid outlet 152, the number of the liquid passage pipes 151 is the same as the number of the liquid outlets 152, the top of the liquid passage pipe 151 is connected to the bottom of the liquid outlet 152, a spiral condenser pipe 154 is provided at the bottom of the liquid passage pipe 151, and the plurality of spiral condenser pipes 154 have the same height and are arranged around A fixing sleeve 155 is clamped on the spiral condenser 154, and the other end of the fixing sleeve 155 is fixedly connected to a fixing column 156, and the other end of the fixing column 156 is fixedly connected to the inner wall of the gas tank 1. A second liquid passing pipe 157 is provided at the bottom of the spiral condenser 154, and a plurality of the second liquid passing pipes 157 are fixed on a guide plate 158.

When the condensing agent is stirred in the stirring chamber 12 for a set time, the automatic liquid outlet valve 153 is opened, and the stirred condensing agent is transmitted from the stirring chamber 12 through multiple liquid outlets 152 along the liquid pipe 151, the spiral condensing pipe 154, and the liquid pipe 2. The surrounding design combination of multiple spiral condensing pipes 154 prolongs the cooling time of the sample gas and accelerates the cooling speed of the sample gas. The fixed sleeve 155 The spiral condenser 154 is fixed, and the fixing column 156 fixes the fixing sleeve 155, so that the spiral condenser 154 is stably fixed on the inner wall of the gas tank 1 to prevent the spiral condenser 154 from falling and being damaged under the action of gravity for a long time. The condensing agent absorbs heat and cools the sample gas in the condensation chamber 13 during the transmission process. When the temperature of the sample gas is reduced, the water vapor in the sample gas 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 to be discharged, collected and processed.

[0045] Example 4

[0047] The working principle and beneficial effects of the above technical solution are as follows: the air outlet pipe 4 fixes the fan 41, and the molecular sieve plate 42 is inserted in the air outlet pipe 4, which is convenient for replacing the molecular sieve plate 42 after being used for a period of time. The fan 41 generates suction to suck out the condensed sample gas in the condensation chamber 13. When the sucked out sample gas passes through the molecular sieve plate 42, the molecular sieve plate 42 adsorbs the residual water vapor in the sample gas, thereby more thoroughly removing the moisture in the sample gas.

[0049] On the basis of Example 4, Figure 1-Figure 2 As shown, the spiral condenser 154 is made of high temperature resistant plastic material, and the fixing sleeve 155 and the fixing column 156 are both made of aluminum alloy material.

[0050] 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 anti-fall performance, is not easy to break or damage, and can maintain good integrity even when accidentally dropped or collided. The high-temperature resistant plastic condenser tube can maintain stable performance at higher temperatures, is not easy to deform or melt, and is suitable for condensation operations under high temperature environments. Although the glass condenser tube can also withstand a certain high temperature, it may break or explode under extremely high temperatures. The fixing sleeve 155 and the fixing column 156 are made of aluminum alloy. The reaction of aluminum and oxygen will form a dense aluminum oxide film on its surface. This film is very hard and corrosion-resistant, and can effectively prevent further oxidation of aluminum, thereby playing a rust-proof role while fixing the spiral condenser tube 154.
