At present, gas concentration detection methods are various, wherein a non-dispersive infrared (NDIR) technology is widely applied to the fields of air quality monitoring, agricultural production, disaster forecast, mine exploration, medical treatment and health care and the like due to good selectivity, high sensitivity, wide detection range and strong anti-interference capability. However, the non-dispersive infrared analysis technique is easily affected by the humidity of the gas, which causes the light intensity signal of the infrared light received by the optical filter of the detection channel to change, thereby affecting the gas concentration measurement result.
Traditional methods for dehumidifying and drying gas mostly adopt adsorbents such as silica gel, anhydrous calcium chloride, molecular sieves and the like, but the adsorption depth of the adsorbents is limited, the dehumidification standard cannot be met, frequent replacement of the adsorbents is troublesome, and more seriously, some adsorbents can adsorb some components in a sample. The condenser drying method is a classic drying technique in the field, and utilizes a refrigeration assembly to cool gas in a gas-liquid separation device, when moist gas is cooled to a dew point, water vapor is condensed from the gas to the inner surface of the gas-liquid separation device, and finally liquid is formed for discharge, so that the water vapor content in air flow is reduced.
As shown in fig. 1, which is a schematic diagram of a conventional gas-liquid separation device, a liquid discharge port is directly connected to the external environment, and a lot of gas escapes from the liquid discharge port while discharging liquid, so that a gas sample to be detected is reduced, the gas circuit gas tightness cannot be guaranteed, and if the gas to be detected is toxic, the gas to be detected can pollute the air of the external environment; on the other hand, the gas to be cooled and the temperature inside the single-leaning device are cooled to the dew point, so that the water vapor in the gas cannot be completely condensed to liquid, and the dryness of the discharged gas cannot be guaranteed.

Example 1
As shown in fig. 3, the utility model provides a high-efficiency gas-liquid separation device for condenser, including gas-liquid separation chamber 3, vertically be provided with in the gas-liquid separation chamber 3 and be used for dividing the gas-liquid separation chamber 3 into air chamber I9 and air chamber II10 division board 4, division board 4 with the upper portion sealing connection of gas-liquid separation chamber 3, the lower part leaves the interval; the top of the air chamber I9 and the top of the air chamber II10 are respectively provided with an air inlet 1 and an air outlet 2, the bottom of the air chamber II10 is provided with a liquid discharge channel 6, the bottom of the liquid discharge channel 6 is connected with a funnel-type liquid discharge port 7, and a floating ball 8 which can float on the liquid level and has a diameter larger than that of the funnel-type liquid discharge port 7 is arranged between the liquid discharge channel 6 and the funnel-type liquid discharge port 7.
In specific implementation, the floating ball 8 can be spherical or ellipsoidal; the floating ball 8 can be made of plastic, foam, wood and the like; the interior of the floating ball 8 can be hollow or solid.
Further, the gas-liquid separation chamber 3 and the partition plate 4 may be made of a stainless steel material, or may be made of another metal material (copper, aluminum, or the like).
In specific implementation, the gas enters the gas chamber I from the gas inlet 1, moves downwards, enters the gas chamber II through the separation between the separation plate 4 and the bottom of the gas-liquid separation chamber after reaching the bottom of the gas chamber I, moves upwards, and finally flows out from the gas outlet 2. In the process, when the water vapor in the gas contacts the inner wall of the low-temperature gas-liquid separation chamber 3 and the partition plate 4 is cooled to the dew point, condensate is formed and flows to the liquid discharge channel 6 along the flow guide plate 5.
As shown in fig. 4, when no condensate is collected in the funnel-type drain port 7, the gas flow rate is small because the pipe diameter sectional area above the floating ball 8 is large; the pipe diameter sectional area below the floating ball is small, so that the gas flow velocity is large.
As can be seen from the bernoulli principle,
;
where p is the pressure at a point in the fluid, v is the flow velocity at the point, ρ is the fluid density, g is the gravitational acceleration, h is the height at the point, and C is a constant.
That is, kinetic energy + gravitational potential energy + pressure potential energy = constant, which can be deduced as follows: when the flow is equal in height, the flow rate is high, and the pressure is low.
Therefore, when no condensate flows to the floating ball, the gas pressure on the upper part of the floating ball 8 is higher than the gas pressure on the bottom part because the gas flow speed on the upper part of the floating ball 8 is lower than that on the bottom part of the floating ball 8, and the gas is prevented from flowing out of the funnel-type liquid outlet 7 because the gas pressure on the upper part of the floating ball is higher than the gas pressure on the bottom part.
However, as the temperature decreases during the transport from the gas inlet 1 to the gas outlet 2, the water vapor in the gas cools to the dew point due to cooling, and condensate is formed. As shown in fig. 5, when the condensate is collected above the floating ball 8, the floating ball 8 is simultaneously influenced by the upward buoyancy, the downward gravity and the pressure difference Δ P between the inside and the outside of the air chamber;
wherein the buoyancy is
Gravity based on>
Based on the pressure difference>
Rho is the density of the liquid, g is the acceleration of gravity, V Row board The volume of the liquid is discharged by the floating ball, m is the weight of the floating ball, n is the molecular weight density of the gas, k is the boltzmann constant, T Inner part 、T Outer cover Respectively, the indoor and outdoor temperatures of the gas-liquid separation chamber.
Because of T Inner part ＜T Outer cover Δ P < 0, so that the external pressure is greater than the pressure in the gas chamber; the increase in height causes the V to be submerged gradually as the condensate gradually floods the float 8 Row board Increasing the buoyancy to which it is subjected. When the floating ball 8 bears upward buoyancy F Floating body And when the pressure is higher than G plus delta P, the floating ball 8 floats upwards and leaves the inner wall of the funnel, so that the condensate can smoothly flow out of the funnel-type liquid outlet 7.
Example 2
This example differs from example 1 in that: as shown in fig. 6, a plurality of layers of flow deflectors I and a plurality of layers of flow deflectors II are respectively disposed in the air chamber I9 and the air chamber II10, positions of each layer of flow deflector 5 of the plurality of layers of flow deflectors I and each layer of flow deflector 5 of the plurality of layers of flow deflectors II are sequentially staggered up and down, and projections of each layer of flow deflector 5 of the plurality of layers of flow deflectors I and each layer of flow deflector 5 of the plurality of layers of flow deflectors II on a plane perpendicular to an air outlet direction have mutually overlapping portions.
It can be understood that the arrangement of the multilayer guide plate I and the multilayer guide plate II is beneficial to increasing the cooling contact area of the water vapor, increasing the retention time of the gas in the gas-liquid separation chamber 3, fully cooling the water vapor in the gas to the dew point, and ensuring that the dehydration rate of the discharged gas reaches more than 95%.
It will be appreciated that the baffle 5 is arranged in an inclined downward direction in order to facilitate the drainage of condensate from the funnel-type drain 7. Specifically, one end of each guide plate 5 of the multilayer guide plate I is fixedly arranged on the inner side wall of the air chamber I9 or on the left side of the partition plate 4, and the other end of each guide plate 5 of the multilayer guide plate I is arranged in a downward inclined manner;
one end of each layer of the guide plate 5 of the multilayer guide plate II is fixedly arranged on the inner side wall of the air chamber II10 or on the right side of the isolation plate 4, and the other end of each layer of the guide plate 5 of the multilayer guide plate II is downwards inclined.
Further, each layer of the guide plate 5 of the multilayer guide plate I is arranged in parallel, and each layer of the guide plate 5 of the multilayer guide plate II is arranged in parallel. In specific implementation, the downward inclination angles of each layer of guide plate of the multilayer guide plate I and each layer of guide plate of the multilayer guide plate II are both 10-60 degrees.
Furthermore, the deflector 5 may be made of stainless steel or other metal (copper, aluminum, etc.).
