Efficient droplet separation device

Abstract

The invention aims at providing an efficient droplet separation device which can solve the technical problem that droplet in a gas phase and a liquid phase are difficult to separate. The device comprises an impact section, an expansion section and a separation section. Gas inlet pipes are symmetrically arranged on the two sides of the impact section, and a lower seal head is arranged at the lowerend of the impact section. The expansion section is communicated with the upper end of the impact section, and the diameter of the expansion section is larger than that of the impact section. The separation section is communicated with the upper end of the expansion section, an annular liquid collecting groove is formed in the inner circular wall of the separation section, a liquid discharging pipe communicated with the annular liquid collecting groove is arranged on the outer wall of the separation section, at least one layer of swirl plate is arranged in the separation section, the swirl plate is located above the annular liquid collecting groove, and an upper seal head with a gas outlet pipe is arranged at the upper end of the separation section.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation, and directly relates to a small droplet high-efficiency separation device. Background technique [0002] Gas-liquid two-phase separation technology is widely used in engineering practice, and the efficiency of gas-liquid two-phase separation directly affects the purity of the product or the effect of subsequent processing. For example, the ammonia separation in the synthetic ammonia production process is to condense the NH3 synthesized by N and H through the ammonia cooler, and then separate the liquid ammonia from the circulating gas through the ammonia separator. The cyclone separator currently used can only separate the liquid ammonia above 10 μm. Smaller droplets are difficult to separate, especially the separation efficiency of 2-3μm droplets is almost zero. These unseparated droplets enter the synthesis system repeatedly with the circulating gas, which not only reduces the pro...

Problems solved by technology

For example, the ammonia separation in the synthetic ammonia production process is to condense the NH3 synthesized by N and H through the ammonia cooler, and then separate the liquid ammonia from the circulating gas through the ammonia separator. The cyclone separator currently used can only separate the liquid ammonia above 10 μm. Smaller droplets are difficult to separate, especially the separation efficiency of 2-3μm droplets is almost zero. These unseparated droplets enter the synthesis system repeatedly with the circulating gas, which not only reduces the production of liquid ammonia, but also The power consumption of the cycle machine is increased, and more importantly, the synthesis of ammonia is affected. It is necessary to study a gas-liquid two-phase separation device that can achieve efficient separation of small droplets.
