Introduction to Gas-Liquid Two-Phase Flow Jet Reactor Technology

Thread Content

The gas-liquid two-phase flow jet reactor is a newly developed technology. This type of reactor utilizes the principle of the density difference between gas and liquid, achieving efficient chemical reactions within the central tube through high-speed injection of gas. Applicable to gas-liquid reaction types in chemical production. Functions of this technology: 1. It has a simple structure, allowing it to be widely applied in various industries within the chemical sector. It has broad application prospects in industries such as petrochemicals, pesticides, and water treatment in the future. II. It can effectively compensate for the shortcomings of bubble columns and tray columns. Sieve plates and bubble caps have their advantages in chemical reactions, but they also present issues such as easy clogging, short operation cycles, complex operation, and the difficulty of removing gases. The central tube of the hyperbola can effectively address the shortcomings of bubble trays and sieve plates. III. If the product of the gas-liquid reaction are crystalline particles, these particles have a significantly larger size compared to those produced using bubble trays or sieve plates, and they also exhibit better uniformity. IV. High reaction efficiency and complete reaction. Since the gas-liquid reaction takes place concentrated within the central tube and the gas velocity is high, molecular collisions are intense. This results in an extremely high efficiency for gas-liquid reactions. Advantages of this technology: 1. Simple structure, easy to maintain. Traditional bubble trays and sieve plates require dozens of layers. One layer of the central tube for the hyperbola is sufficient. The production capacity of the reaction can be increased exponentially by paralleling the central tubes. II. If the product is in the form of crystalline particles, it features large and uniform particles. The supersaturation of the central tube jet reaction is lower than that of conventional bubble columns and sieve plates. So the crystalline particles are good. III. The one-time cost of the tower is low. It is about 1/3 of the equipment manufacturing cost for traditional bubble columns and tray towers. IV. The tower diameter and height can be significantly reduced compared to traditional bubble columns and tray towers. For the same production capacity, the diameter of traditional towers is generally between 3 meters and 4 meters. The tower diameter of this technology can be as large as 3 meters, and as small as 1 meter. Same production capacity. The height of traditional towers is 30–40 meters (including the exhaust section), while the height of towers using this technology is 20 meters. (Volume including the exhaust section) V. It can significantly reduce the tower pressure. For every 10 meters the tower height is reduced, the tower pressure decreases by 0.1 MPa. By using this reactor, compared to traditional tower types such as sieve trays and bubble columns, the tower pressure can be significantly reduced.
