Description

Improved generation reation kettle oxygen distributor

Technical Field

The utility model relates to the technical field of chemical industry, specifically an improved generation reation kettle oxygen distributor.

Background

In the practice of chemical production, the application of the reaction kettle is extremely wide. Taking a phi 3800X 19000 pressure leaching kettle as an example, the reaction kettle is a horizontal five-compartment stirring device with one stirrer arranged in each compartment. The operating pressure is 1.4MPa, and the operating temperature is 190 ℃; the operation medium is nickel sulfate ore pulp and industrial pure oxygen; when the vehicle is started, the steam coil is required to be used for heating, and when the vehicle is stopped, the steam coil cools materials and then the materials are unloaded; the slurry is fed from the top of the first compartment and oxygen is fed from the bottom of each compartment; partition walls are arranged among the compartments, the liquid levels of the compartments are sequentially reduced from front to back by the top of each partition wall in an overflow mode, and the ore pulp after reaction is discharged from the upper part of the fifth compartment through an insertion pipe; the gas is discharged through a tail gas discharge pipe (arranged at the top of the fifth compartment). During operation, the medium in the equipment is three phases of gas, liquid and solid, the distance from the gas-liquid interface of the horizontal equipment to the inner wall of the top of the equipment is about 800mm, and the ore pulp mainly comprises 1-2 percent (mass percent) of dilute sulfuric acid and 10-12.5 percent (mass percent) of solid raw material particles. When the equipment works, solid raw material particles are uniformly suspended in liquid by stirring of the stirrer of each compartment, and oxygen is uniformly distributed in ore pulp, so that the contact area is enlarged as much as possible, and the gas-liquid-solid three-phase reaction is realized. The reaction ore pulp enters five compartments from front to back for reaction, the added oxygen is insoluble in dilute sulfuric acid liquid, and due to the action of the static pressure of an ore pulp liquid column, unreacted oxygen can overflow from the liquid surface and enter a gas phase space to separate from the reaction; meanwhile, the reaction is weak, the added oxygen (especially the flue gas entering each compartment) is generally excessive, and the gas phase space is communicated, so the utilization rate of the oxygen is not high, and the design of the pressure leaching kettle requires oxygen feeding. Because the ore pulp is raw material particles suspended in dilute sulfuric acid, the upward opening tubular oxygen feeding mode is not feasible. The design difficulties and the key points of the oxygen inlet distributor are anti-blocking, solid particle precipitation blocking prevention and uniform gas distribution.
