[0024] like Figure 1 As shown, the cyclone dehydrator includes a shell 1, which is cylindrical. An air outlet 9 is arranged at the top of the shell 1. A funnel-shaped water storage bin 10 is arranged at the bottom of the shell 1, and a drain port 11 is arranged at the bottom of the water storage bin 10; between the drain port 11 and the air outlet 9, a multiple-speed demister 6, a liquid baffle plate 5, a separator 4, a water collecting funnel 3 and a wire mesh demister 2 are arranged in sequence from bottom to top. A through hole 14 is arranged in the middle of the liquid baffle plate 5 for gas to pass through. A small hole is arranged in the middle of the liquid baffle plate 5, the separator 4 and the water collecting funnel 3 for the pipe 12 to pass through. A pipe 12 is arranged at the bottom end of the water collecting funnel 3, and the pipe 12 passes through the small hole of the separator 4, the through hole 14 of the liquid baffle plate 5 and the small hole of the multiple-speed demister 6 in sequence. An air inlet pipe 7 is arranged on the shell 1 at the multiple-speed demister 6. The air inlet pipe 7 is arranged tangentially relative to the shell 1. The air inlet pipe 7 is aligned with the disconnection of the concentric arc baffle 15 of the multiple-speed demister 6. This application adopts pure physical separation technology, which can effectively separate liquid and gas, remove the mist entrained in the gas, improve the drying effect of the output gas, improve the gas dehydration effect, thereby improving the gas combustion efficiency and the service life of gas equipment. The material of the water storage bin 10 is a carbon steel lined stainless steel composite plate, which is both economical and durable, avoids liquid corrosion of stainless steel, and improves the service life of the dehydrator.
[0025] like Figure 2 As shown, the separator 4 is installed on the inner wall of the housing 1 through the bracket 13. The separator 4 has a small upper part and a large lower part, and a ventilation gap is left between the separator 4 and the housing 1. The gas filled in the separator 4 contacts the separator 4, and the separator 4 condenses the residual water droplets in the gas, further improving the gas-liquid separation effect.
[0026] like Figure 3 As shown, the liquid baffle plate 5 is welded and fixed to the inner wall of the shell 1 on all sides, and the cross section of the liquid baffle plate 5 is trapezoidal. The liquid droplets gathered in the cylinder at the upper part of the equipment are settled to the water storage bin 10. A water collecting pipe 8 is arranged on one side of the liquid baffle plate 5, and the water collecting pipe 8 extends along the inner wall of the shell 1 to the water storage bin 10. The liquid baffle plate 5 collects the liquid droplets, and the liquid droplets pass through the water collecting pipe 8 to the lower drain port 11 to prevent the separated liquid from penetrating into the incoming gas. The water collecting pipe 8 is close to the inner wall of the shell 1 to save space.
[0027] like Figure 4As shown, when working, the gas and water mixed medium enters the multiple-speed demister 6 tangentially from the air inlet pipe 7, and the airflow is divided into several strands by the concentric arc baffle 15, which rotate axially in one direction respectively. The water droplets and dust particles produce a large centrifugal acceleration and collide with the wall plate to lose kinetic energy and flow down along the wall plate to initially separate the gas and water. The initially separated water flows into the lower water storage bin 10. The gas after the initial separation flows upward and enters the upper baffle area to flow in a curve. The gas passes through the middle through hole of the liquid baffle plate 5 and hits the separator 4 and the water collecting funnel 3. Under the action of impact force and gravity, the water droplets and dust lose kinetic energy after hitting the baffle components. Under the action of adhesion, a water film is formed and accumulated into large water droplets and flows down to the lower water storage bin 10. The airflow continues to rise and passes through the wire mesh demister 2 to further separate the gas and water and remove the mist. The wire mesh demister 2 can not only filter out the larger liquid foam suspended in the airflow, but also filter out the tiny mist to ensure the mass transfer efficiency. A part of the water droplets condensed on the wire mesh demister 2 drips from the water collecting funnel 3 along the pipe 12 to the water storage bin 10, and the other part drips along the inner wall of the shell 1 to the liquid baffle 5 through the water collecting pipe 8 to the water storage bin 10, and then passes through the drain outlet 11.
