Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of petroleum chemical industry, in particular, to a muffler connecting device and a muffler. BACKGROUND

[0002] The vent muffler used in the petroleum chemical plant is generally installed at the highest position of the plant or structure near the equipment to avoid the influence of medium noise and temperature hazards. In order to resist dynamic loads such as wind load and earthquake load and ensure its own stability, the muffler is usually fixedly installed, and the pipeline system connected therewith needs to use natural compensation or compensator compensation to realize the flexibility necessary for the pipeline system and ensure the safe operation of the pipeline system.

[0003] Generally, the vent pipeline is rigidly connected with the bottom inlet pipe of the muffler body. Since the vent pipeline will have a large temperature change during use, strong thermal expansion and contraction phenomenon will occur, and great thermal stress will be generated at the rigid connection part, which may even cause failure and damage of the pipeline system or equipment.

[0004] However, with the continuous development of large-scale petroleum chemical plants, the diameter of the vent pipeline is continuously increased, and the size and weight of the muffler are also greatly increased. It is very difficult for the muffler to be fixedly installed and for the pipeline system connected therewith to realize natural compensation and compensator compensation, which requires a large space to be realized and increases the material cost and construction difficulty.
