A device for quickly and uniformly adding diluent and inhibitor when stirring fails

Abstract

The invention discloses a device for quickly and uniformly adding diluent and inhibitor when stirring fails, which includes a reaction tank, a storage tank 1, a storage tank 2 and a storage tank 3, the inhibitor is placed in the storage tank 1, and the storage tank 2 is placed Diluent, cooling solvent is placed in the third storage tank, the first storage tank, the second storage tank and the reaction tank are connected through the main feeding pipeline, the middle section of the main feeding pipeline is provided with a feeding pump and an inlet valve, and the main feeding pipeline The tail section is located below the stirring paddle, and the tail section is in the shape of a coil, with several feeding holes distributed on the disk surface; the reaction tank and the storage tank three are connected by the main discharge pipe, and the front section of the main discharge pipe is set There is a safety valve, the middle section of the discharge main pipe is provided with an outlet valve, the tail section of the discharge main pipe is located on the top of the reaction tank, the tail section is coiled, and there are several discharge holes distributed on the disk surface. The device quickly stops runaway reactions by adding diluents and inhibitors to the reaction tank.

Description

technical field [0001] The invention relates to the technical field of active prevention and control measures for rapid and uniform addition of uncontrolled diluent and inhibitor under the condition of stirring failure, in particular to a device for quickly and uniformly adding uncontrolled diluent and inhibitor when stirring fails. Background technique [0002] Most production devices in the petrochemical field are equipped with stirring devices. During the production process of petrochemical devices, stirring mainly plays the role of dispersing materials, enhancing mass transfer and heat transfer. Stirring failure widely exists in the production process of the petrochemical industry. Once the stirring fails, it will cause local monomer overconcentration or local overheating in the reaction system, which will cause the reaction system to deviate from the normal reaction conditions. If no effective measures are taken , will lead to serious consequences. [0003] According t...

Problems solved by technology

However, at present, most production enterprises add diluents and inhibitors into the reaction system through the material pipeline on the top of the device reactor. Due to the failure of the stirring device, the diluents and inhibitors cannot be uniformly dispersed, especially some polymers with larger molecular weights. During the production process, the viscosity of the reaction system is relatively high, so diluents and inhibitors cannot be quickly and evenly dispersed into the reaction system, and it is difficult to prevent the reaction from getting out of control.
