Device for adding diluent and inhibitor rapidly and uniformly in case of stirring failure

Abstract

The invention discloses a device for adding diluent and inhibitor rapidly and uniformly in case of stirring failure. The device comprises a reaction tank, a first storage tank, a second storage tank and a third storage tank, the inhibitor is placed in the first storage tank, the diluent is placed in the second storage tank, cooling solvent is placed in the third storage tank, the first storage tank and the second storage tank are connected with the reaction tank through a main feed pipeline, a feed pump and an inlet valve are arranged on the middle segment of the main feed pipeline, the tail segment of the main feed pipeline is located below a stirring paddle, the tail segment is in a coil shape, and multiple feed holes are distributed in the coil surface; the reaction tank is connected with the third storage tank through a main discharging pipeline, a safety valve is arranged on the front segment of the main discharging pipeline, an outlet valve is arranged on the middle segment of the main discharging pipeline, the tail segment of the main discharging pipeline is located at the top of the reaction tank, the tail segment is in a coil shape, and multiple discharging holes are distributed in the coil surface. According to the device, by adding the diluent and the inhibitor into the reaction tanks, the occurrence of out-of-control reaction can be prevented rapidly.

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.
