One group of double-turbulence loop reactor

Abstract

The invention provides one group of double-turbulence loop reactor and relates to chemical equipment. The group of double-turbulence loop reactor comprises a fluid inlet, an axial flow circulating pump, a fluid outlet, elbows and loop reactor pipe sections with jackets, and is characterized in that a static mixing turbulent flow component is arranged in an inner pipe of each reactor pipe section; a turbulent flow component is arranged in the jacket of each loop reactor pipe section; the turbulent flow component in the pipe is a column-shaped, sheet-shaped, curved surface-shaped, strip-shaped and spiral static mixing component with a turbulent flow effect; the turbulent flow component in the jacket has a spiral sheet type, a turbulent flow column type and a combined type of the spiral sheet type and the turbulent flow column type; the pipe length of the pipe section is 6 m, the inner diameter of the inner pipe is 600 mm, and the spiral sheet in the jacket has the thickness of 10 mm and the screw pitch of 100 mm; the loop reactor pipe sections (5) with the jackets are connected through the elbows (4); and two loop reactor pipe sections belong to one group. The group of unit reactor has reasonably matched design parameters and best benefits, can be used singly or in a combined mode, and has higher operating elasticity compared with the existing loop reactor.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a unit group of double disturbance loop reactors. Background technique [0002] Loop reactors are suitable for slow reaction processes that require a long residence time, such as olefin polymerization. The reactor operates continuously, fresh reactants are continuously fed into the loop pipe of the reactor through the inlet to react while circulating, and the reactor outlet is continuously discharged. By changing the loop length, circulation ratio, and circulation flow rate to adapt to the residence time required by the chemical reaction, in its structural design, the loop length, circulation ratio are directly proportional to the residence time, and the circulation flow rate is inversely proportional to the residence time. When the circulation ratio tends to infinity, the corresponding ideal reactor model is a fully mixed tank. [0003] In order to fully mix the fluid in the existing loop...

Problems solved by technology

But when the diameter of the reactor is large, the simple jacket heat transfer is not ideal, and the thermal resistance measured by the jacket will become the bottleneck of convective heat transfer
