The utility model is characterized in that the stream-turn float valve comprises a valve cylinder; an air-stream orifice communicated with an air-stream cavity of the valve cylinder is formed on the valve cylinder; an air-stream guiding plate inclining toward the inner side of the air-stream orifice is arranged on the valve cylinder; the upper end of the valve cylinder is fixedly connected with a valve plate; a valve hole is formed on the valve plate; a valve bonnet is fixedly connected with the valve plate; horizontal side openings are formed on the valve bonnet; the air-stream cavity of the valve cylinder is communicated with the horizontal side openings of the valve bonnet through the valve hole formed on the valve plate; the air-stream orifice of the valve cylinder is divided into three air-stream orifices distributed at the angle of 120 degrees in the circumferential direction of the valve cylinder; three horizontal side openings are formed uniformly on the peripheral wall of the valve bonnet; and the diameter of the valve plate is 1.4 to 1.8 times of that of the valve cylinder. Compared with a normal float valve, the stream-turn float valve of the utility model enables the gas and the liquid phases of the separated materials to be fully in contact with each other, improves the tower plate efficiency by 10 to 15 percent and the production capacity by 15 to 20 percent, and has the advantages of good effect of gas-liquid mass and heat transfer, high plate efficiency, and simple structure.
Description
Technical field
The utility model relates to chemical separating tower parts, is a kind of turn of tidal stream float valve of chemical separation processes such as the drying that is used for material, purification, purification, rectifying.
Background technology
At present, the employed common float valve of chemical separating tower, can satisfy the needs of general chemical separation process, but exist fully heat and mass of gas-liquid phase, plate efficiency is low, production capacity or product quality also are restricted etc. not enough relatively, therefore in actual production in order to reach the separation index, number of actual plates is far away more than theoretical cam curve.Increasing of the number of plates not only increased equipment investment, and increased tower height, increased the energy consumption of chemical separation process.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the shortcoming of prior art, provide a kind of and can make the more abundant contact mutually of separated material gas-liquid, the abundant mutually heat and mass of gas-liquid, plate efficiency height, turn of tidal stream float valve simple in structure.
Solving the technical scheme that its technical problem adopts is: a kind of turn of tidal stream float valve, it is characterized in that, it comprises valve cylinder, be provided with the airflow orifice that is communicated with the air flow chamber of valve cylinder on valve cylinder, the air-flow prerotation vane to the inboard inclination of airflow orifice is set on valve cylinder, the upper end and the valve block of valve cylinder are connected, on valve block, be provided with valve opening, be fixed with bonnet on valve block, the horizontal side mouth is set on bonnet, the air flow chamber of valve cylinder is communicated with the horizontal side mouth of bonnet by the valve opening of valve block.
The airflow orifice of described valve cylinder is 120 ° of uniform three airflow orifices at the circumferencial direction of valve cylinder.
The horizontal side mouth of described bonnet on the bonnet perisporium uniform three.
The diameter of described valve block is 1.4-1.8 a times of valve cylinder diameter.
Turn of tidal stream float valve of the present utility model, owing on the valve cylinder of turn of tidal stream float valve, be provided with the airflow orifice that is communicated with the valve cylinder air flow chamber, air-flow prerotation vane to the inboard inclination of airflow orifice is set on valve cylinder, gaseous substance enters air flow chamber from the valve cylinder bottom, the air-flow prerotation vane that tilts stop with water conservancy diversion under, tangential direction ejection from the valve cylinder airflow orifice along valve cylinder forms eddy flow, and the gaseous substance liquid phase substance abundant and on the column plate of eddy flow is contacted, and helps the heat and mass of gas-liquid phase material; Because the valve block diameter of turn of tidal stream float valve is 1.4-1.8 a times of valve cylinder diameter, the valve block diameter has prolonged gas-liquid phase flow of matter path greater than the valve cylinder diameter, has further increased the abundant contact effect of gas-liquid phase material again; Also be communicated with the horizontal side mouth of bonnet by the valve opening on the valve block owing to the valve cylinder air flow chamber, rising again behind the gaseous substance horizontal direction of the horizontal side mouth of bonnet ejection and the abundant heat and mass of liquid phase substance on the column plate, and the valve cylinder airflow orifice contacts back speed in the horizontal direction along the gaseous substance of the tangential direction of valve cylinder ejection and liquid phase substance on the column plate and descends liquid foam entrainment amount minimizing when rising again.Compare with existing common float valve, turn of tidal stream float valve of the present utility model, the full contact of gas-liquid two-phase material, heat and mass is effective, can improve plate efficiency 10-15%, improves production capacity 15-20%.
