Description

Technical Field

[0001] This invention relates to the field of flue gas sampling and dehydration technology, and in particular to a gas-water separator. Background Technology

[0002] When environmental monitoring departments use flue gas samplers to sample flue gas, the flue gas must be dehydrated and dried before entering the detection instrument to ensure measurement accuracy and avoid damaging the main unit.

[0003] The current method for dehydrating and drying flue gas is to add a gas-water separator at the gas inlet. The gas-water separator is generally made of rigid plastic and is generally divided into a condensation chamber and a drying chamber. The flue gas first passes through the condensation chamber to condense water vapor, and then enters the drying chamber, where the color-changing silica gel in the drying chamber dries the flue gas. Modern condensation chambers typically have an impact pipe. The flue gas enters through the inlet of the impact pipe, and the outlet faces the inner wall of the condensation chamber. The high-temperature, high-pressure flue gas condenses due to the temperature difference between itself and the inner wall. However, since the impact pipe usually has only one outlet, the flue gas ejected from this single outlet condenses upon impact with the inner wall. Furthermore, because the condensation chamber wall is made of plastic, the temperature difference between the flue gas and the inner wall is not significant, resulting in poor condensation. The condensed flue gas has high humidity, and its drying efficiency in the drying chamber is not high, leading to incomplete drying. This incomplete drying makes the instrument susceptible to corrosion from water vapor, thus shortening the lifespan of the flue gas testing instrument. Summary of the Invention

[0004] The purpose of this invention is to provide a gas-liquid separator with high drying efficiency.

[0005] To achieve the above objectives, this invention discloses a gas-liquid separator, comprising a housing, a gas-diverting pipe and a gas outlet pipe connected to the housing, a condensation chamber and a drying chamber inside the housing, the gas-diverting pipe being connected to the condensation chamber, and the upper part of the gas-diverting pipe being an inlet section. The lower part of the flow-impact duct is connected to multiple exhaust pipes. A conical diverter is installed inside the flow-impact duct to divert the flue gas entering from the intake section into each exhaust pipe. All exhaust pipes open towards the side wall of the condensation chamber. A metal plate is installed between the exhaust pipe and the side wall of the condensation chamber, and the metal plate has multiple small holes. A filter screen is installed on the upper wall of the condensation chamber, and the filter screen leads to the drying chamber. A desiccant is installed in the drying chamber, and the exhaust pipe leads to the drying chamber.

[0006] Preferably, the bottom of the condensation chamber is provided with a drain port, and a plug can be detachably installed on the drain port.

[0007] Preferably, the drying chamber is provided with a vertical partition plate, which divides the drying chamber into a first chamber and a second chamber. A communication port is provided between the first chamber and the second chamber. The condensation chamber is connected to the first chamber through a filter screen. The air outlet pipe is located at the top of the second chamber.

[0008] Preferably, the upper part of the partition plate is connected to the top of the inner wall of the housing, and the lower part of the partition plate is left with a gap to the bottom of the inner wall of the housing to form a communication opening.

[0009] Preferably, the bottom of the inner wall of the housing is provided with a material outlet, the material outlet is located below the partition plate, the material outlet is located below the communication port, and an end cap can be detachably installed on the material outlet.

[0010] Preferably, the upper part of the housing is provided with a handle.

[0011] Preferably, all exhaust pipes are arranged in a ring along the axis of the split-flow impingement pipe.

[0012] Preferably, there are four exhaust pipes and four metal plates. The four exhaust pipes open toward the front wall, rear wall, left wall and right wall of the condensation chamber, respectively, and the metal plates are arranged in a one-to-one correspondence with the exhaust pipes.

[0013] The beneficial effects of this invention are as follows: The gas-liquid separator of this invention includes a housing, which contains a condensation chamber and a drying chamber. After the flue gas enters the diversion and impact pipe, it impacts the conical diverter inside the diversion and impact pipe. The conical diverter divides the flue gas into each exhaust pipe. The flue gas ejected from the exhaust pipe first impacts a metal plate, and part of the flue gas liquefies upon cooling. Part of the flue gas passes through small holes in the metal plate and impacts the inner wall of the condensation chamber, liquefying a second time upon cooling. Then, part of the flue gas impacting the inner wall of the condensation chamber bounces back to the other side of the metal plate, liquefying a third time upon cooling. The flue gas entering through the inlet port undergoes multiple cooling and liquefaction processes, achieving efficient condensation and liquefaction of the flue gas. The drying chamber contains a desiccant, which is connected to the drying chamber through a filter screen at the upper end of the condensation chamber, so that the condensed flue gas is dried by the desiccant and flows out through the outlet port, resulting in high drying efficiency.

[0020] refer to Figure 1 and Figure 2 A gas-liquid separator includes a housing 100, on which a diversion gas-impact pipe 400 and a gas outlet pipe 150 are connected. The housing 100 contains a condensation chamber 110 and a drying chamber 120. The diversion gas-impact pipe 400 is connected to the condensation chamber 110. The upper part is the air intake section. Multiple exhaust pipes 420 are connected to the lower part of the diverting and impacting air pipe 400. A conical diverter 410 is installed inside the diverting and impacting air pipe 400. The conical diverter 410 is used to divert the flue gas entering from the air intake section into each exhaust pipe 420. All exhaust pipes 420 open towards the side wall of the condensing chamber 110. A metal plate 200 is provided between the exhaust pipe 420 and the side wall of the condensing chamber 110. The metal plate 200 has multiple small holes 210. A filter screen 140 is provided on the upper wall of the condensing chamber 110, and the filter screen 140 leads to the drying chamber 120. A desiccant is provided inside the drying chamber 120, and the exhaust pipe 150 leads to the drying chamber 120. Figure 1 The arrows indicate the flow path of the flue gas inside the gas-liquid separator. The gas-liquid separator in this design includes a housing 100, which contains a condensation chamber 110 and a drying chamber 120. The flue gas enters the diversion and impact pipe 400. Then, it impacts the conical distributor 410 inside the diverter pipe 400. The top of the conical distributor 410 extends into the intake section. The exhaust pipes 420 are distributed near the bottom of the conical distributor 410. The conical distributor 410 diverts the smoke and dust gas into each exhaust pipe 420. The smoke and dust gas ejected from the exhaust pipes 420 first impacts the front of the metal plate 200, and some of the smoke and dust gas liquefies upon cooling. Some of the smoke and dust gas passes through the small holes 210 on the metal plate 200 and impacts the inner wall of the condensation chamber 110, liquefying a second time upon cooling. Then, some of the smoke and dust gas impacting the inner wall of the condensation chamber 110 bounces back to the other side of the metal plate 200, liquefying a third time upon cooling. Moreover, the length of the metal plate can... The flue gas, designed to extend near the bottom of the condensing chamber, bounces off the opposite side of the metal plate 200 and then bounces again onto the inner wall of the condensing chamber 110, where it liquefies upon cooling. This process repeats multiple times between the opposite side of the metal plate 200 and the inner wall of the condensing chamber 110, resulting in highly efficient condensation and liquefaction of the flue gas. The water droplets formed by the liquefied flue gas settle and collect in the condensing chamber 110 under gravity. Because the metal plate extends near the bottom of the condensing chamber, the lower part of the metal plate is gradually submerged by condensate, which cools the metal plate, allowing subsequent flue gas to liquefy more quickly upon impact. A desiccant is provided in the drying chamber 120 and is connected to the filter 140 at the upper end of the condensing chamber 110. This allows the condensed flue gas to be dried by the desiccant and then flow out through the outlet pipe 150, resulting in high drying efficiency. The desiccant can be color-changing silica gel, and the shell 100 can be made of rigid plastic and transparent to facilitate observation of the color change of the internal silica gel.

[0021] In one embodiment, to facilitate the timely discharge of condensate, a drain port is provided at the bottom of the condensation chamber 110, and a plug 170 is detachably installed on the drain port.

[0022] In one embodiment, a vertical partition plate 160 is provided inside the drying chamber 120, dividing the drying chamber 120 into a first chamber and a second chamber. A communication port is provided between the first chamber and the second chamber. The condensation chamber 110 is connected to the first chamber through a filter screen 140. The exhaust pipe 150 is located at the top of the second chamber. The partition plate 160 divides the drying chamber 120 into the first chamber and the second chamber. The condensed flue gas enters the first chamber through the filter screen 140, then enters the second chamber through the communication port. After being dried by the desiccant in the first and second chambers, it is discharged from the exhaust pipe 150.

[0023] In one embodiment, the upper part of the partition plate 160 is connected to the top of the inner wall of the housing 100, and the lower part of the partition plate 160 has a gap with the bottom of the inner wall of the housing 100 to form a communication opening. Because the lower part of the partition plate 160 has a gap with the bottom of the inner wall of the housing 100 to form a communication opening, a U-shaped air passage is formed inside the drying chamber 120, increasing the path of the flue gas within the drying chamber 120 and improving the drying effect.

[0024] In one embodiment, a material inlet is provided at the bottom of the inner wall of the housing 100, located below the partition plate 160 and below the connecting port. An end cap 180 is detachably installed on the material inlet. To facilitate desiccant replacement, a material inlet is provided at the bottom of the inner wall of the housing 100. The location of the material inlet below the connecting port allows for the simultaneous discharge or injection of desiccant from the first and second chambers.

[0025] In one embodiment, a handle 190 is provided on the upper part of the housing 100 to facilitate lifting the gas-water separator.

[0026] In one embodiment, all exhaust pipes 420 are arranged in a ring along the axis of the diversion and impact pipe 400. The smoke and gas ejected from the exhaust pipes 420 first pass through the small holes 210 on the metal plate 200 and then impact the inner wall of the condensation chamber 110. The ring arrangement of all exhaust pipes 420 along the axis of the diversion and impact pipe 400 effectively utilizes the temperature difference between each side wall of the condensation chamber 110 and the smoke and gas, further improving the liquefaction efficiency.

[0027] In one embodiment, there are four exhaust pipes 420 and four metal plates 200. The four exhaust pipes 420 open towards the front, rear, left, and right side walls of the condensing chamber 110, respectively. The metal plates 200 are arranged in a one-to-one correspondence with the exhaust pipes 420. The smoke and gas ejected from the exhaust pipes 420 first pass through the small holes 210 on the metal plates 200 and then impact the inner wall of the condensing chamber 110. The temperature difference between the four side walls of the condensing chamber 110 and the smoke and gas is relatively large. The fact that the four exhaust pipes 420 are respectively oriented towards the four side walls of the condensing chamber 110 helps to improve liquefaction efficiency.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
