[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0018] As shown in the drawings, Figure 1 The embodiments of the present application disclose a vertical separation device of a steam injection boiler, which comprises a tank 1, a first separation device 2, a second separation device 3, a first mist eliminator 4 and a second mist eliminator 5. The tank 1 has a steam outlet 11 at the top, a drain 12 at the bottom and a steam inlet 13 at the side. The first separation device 2, the second separation device 3, the first mist eliminator 4 and the second mist eliminator 5 are installed in the tank 1 from bottom to top in sequence, and the first separation device 2 is located above the steam inlet 13. In this embodiment, the first separation device 2 is a cyclone separation device, the second separation device 3 is a wave plate steam-water separator, the first mist eliminator 4 is a wave plate mist eliminator, and the second mist eliminator 5 is a porous partition plate. The present application can improve the separation effect, improve the steam superheat degree and dryness through multiple separation and multiple demisting.
[0019] In order to further optimize the technical solutions of the present application, the first separation device 2, the second separation device 3, the first mist eliminator 4 and the second mist eliminator 5 are all annular, so as to form a space through which a high-pressure water gun passes, facilitating subsequent cleaning.
[0020] In order to further optimize the technical scheme of the utility model, the inner wall of the tank body 1 is finely ground to have a roughness of 0.4-0.8, so as to reduce the scale adhesion and reduce the risk of blockage.
[0021] The working principle of the utility model is as follows:
[0022] After the steam enters the tank body 1 from the steam inlet 13, it first enters the cyclone separation device, the gas and the liquid flow together in rotation, the steam direction is controlled, the first gas-liquid separation is realized by using the centrifugal force, then the gas reaches the wave-shaped plate steam-water separator for secondary steam-water separation (the wave-shaped plate steam-water separator realizes steam-water separation by the action of the micro vortex and the centrifugal force: when the steam-water mixture enters the wave-shaped plate steam-water separator from the liquid inlet, the micro vortex motion occurs in the gap of the wave-shaped plate, the centrifugal force generated by the motion can separate the gas and the steam-water, in the gap of the wave-shaped plate, the bubbles will gather to form larger bubbles under the action of the centrifugal force, and the water drops will be compressed to smaller water drops by the centrifugal force, and then gradually deposit on the wave-shaped plate and be discharged from the drain outlet 12), next, the steam hits the wave-shaped plate demister, the mist drops gather to form a water flow, and fall from the drain outlet 12 due to the action of gravity; finally, the steam reaches the perforated partition plate for once again gas-liquid separation (when the fluid or gas passes through the holes of the perforated partition plate, due to the size and shape limitation of the holes, part of the substances will be blocked on the perforated partition plate, and another part will continue to flow through the holes, the substances blocked on the perforated partition plate will gradually accumulate to form a substance layer on the perforated partition plate, and the substances passing through the holes will continue to flow, and with the passage of time, the substance layer will gradually thicken, thereby realizing the separation of the substances), and finally the steam is output from the steam outlet 11, and the liquid is discharged from the drain outlet 12 to enter the subsequent mixing process.
