Anti-leakage reinforcing device for outer coil pipe of reaction kettle

Abstract

The invention discloses an anti-leakage reinforcing device for an outer coil pipe of a reaction kettle. A reaction kettle body is included. An outer coil pipe heating device is installed on the outer surface of the reaction kettle body, and the outer coil pipe heating device comprises an outer coil pipe body, an outer coil pipe inlet and an outer coil pipe outlet. The outer coil pipe main body is assembled from a plurality of pipelines by welding. Each pipeline sequentially comprises an outer layer, a reinforcing layer and an inner layer from outside to inside, and a plurality of flow limiting plates are mounted on the inner wall of the inner layer. A protective shell is mounted on the outer surface of the outer coil heating device and on the reaction kettle body; a cavity is formed in the protective shell; a plurality of groups of damping blocks are mounted on the two side walls of the cavity; and an elastic piece is fixed between the damping blocks in each group. Supporting legs are mounted at the bottom of the reaction kettle body. The anti-leakage reinforcing device is reasonable in structural design, and can enhance the overall strength of the outer coil pipe, enable the outer coil pipe to bear larger impact and guarantee that the outer coil pipe cannot leak.

Description

technical field [0001] The invention relates to the related technical field of anti-leakage strengthening of the outer coil of a reaction kettle, in particular to an anti-leakage strengthening device for the outer coil of a reaction kettle. Background technique [0002] For working conditions with low temperature requirements, according to the heat transfer form, it is generally divided into two types of reactors: coil type and jacket type. In recent years, the coil reactor has gradually become the mainstream. The coil is divided into an outer coil and an inner coil. The outer coil is mainly used for heating, and the inner coil is mainly used for cooling. [0003] The outer coil reactor is composed of a kettle body, a kettle cover, an outer coil jacket, an agitator, a transmission device, a shaft seal device, and a support. The outer coil reactor can withstand high pressure, which can reduce the plate thickness of the inner cylinder, and the inner cylinder is divided into s...

Problems solved by technology

However, the outer coil is under pressure for a long time, and the internal fluid expands with heat and contracts with cold, which has a huge impact on the longitudinal weld and is prone to leakage.
