Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, in the centrifugal gas-liquid separator for desulfurization of blast furnace gas in the present embodiment, the centrifugal gas-liquid separator is fixed in the middle section inside the desulfurization tower, and separates gas from liquid in the desulfurization tower. The centrifugal gas-liquid separator comprises a wind breaking shaft 1, wherein a plurality of separation blades 2 are circumferentially arranged on the wind breaking shaft 1, and the separation blades 2 are uniformly arranged at intervals. The inner edge 2.1 of the separating blade 2 is fixedly connected with the surface of the wind breaking shaft 1, and the inlets of the separating blade 2 are respectively arranged in tangency with the flow direction of the coal gas. The windward side 2.3 of the separation blade 2 is respectively provided with a plurality of arc-shaped liquid guide pieces 2.4. The outer sides of the separation blades 2 are surrounded by check rings 3, and the outer edges of the separation blades 2 are fixedly connected with the inner walls of the check rings 3 respectively. The upper surface of the retainer ring 3 is annularly provided with a water collecting tank 3.1, the bottom of the water collecting tank 3.1 is provided with a plurality of drain holes, the drain holes are respectively connected with the drain pipe 4, and the number of the drain holes is determined according to the engineering water displacement. The coal gas in the desulfurizing tower flows in through the inlet of the separating blade 2, the liquid film on the surface of the separating blade 2 is automatically guided into the water collecting tank 3.1 through the liquid guiding piece 2.4 due to the inertia effect, and then flows into the drain pipe 4 through the drain hole and is discharged. The retaining ring 3 can prevent the water flow in the water collecting tank 3.1 from flowing to the inner wall of the desulfurizing tower, and ensures that the water is not secondarily mixed with the coal gas in the tower.
The bottom of the wind breaking shaft 1 is of a conical structure, so that the resistance of the bottom of the wind breaking shaft 1 to coal gas is reduced. The bottom end surface of the wind breaking shaft 1 is provided with a plurality of obliquely arranged separation grooves 1.1, and the number of the separation grooves 1.1 is matched with the amount of coal gas; and the included angle alpha between the separation groove 1.1 and the central line of the wind breaking shaft 2 is 30-45 degrees, and the separation groove on the surface of the wind breaking shaft 1 is utilized to separate liquid drops in advance, so that the gas-liquid separation effect is further improved.
Above-mentioned drain spare 2.4 is for leading liquid lug or leading liquid recess, not only can increase 2 surface areas of separation blade and roughness, makes the air current more disorderly, and gas-liquid separation is more thorough, plays the water conservancy diversion effect to the liquid film moreover, increases the centrifugal force of horizontal direction when the liquid film flows. When the liquid film leaves the separation blade, the liquid film can smoothly enter the water collection tank without external force.
This application can carry out abundant gas-liquid separation to the coal gas after the desulfurization, has improved gas-liquid separation's effect, and the retaining ring has prevented that the rivers in the water catch bowl from flowing into the desulfurizing tower inner wall, has guaranteed that moisture does not mix with the coal gas secondary in the tower.
