Damping Tank Core Definition & Functions

Core Definition & Functions

The damping tank is a key buffering and pressure-stabilizing component in the oil and gas delivery pipeline of the batch-type waste tire pyrolysis system, which is mostly connected in series between the steam drum and the condensation system. Its core function is to eliminate the violent fluctuations in the flow rate and pressure of oil and gas caused by the batch process (the batch-type changes from the peak gas production in the middle stage of pyrolysis to the low flow rate in the initial and final stages), stabilize the flow rate and pressure of oil and gas entering the condensation system, and prevent condenser material scouring, pipeline vibration or seal leakage caused by abrupt pressure rises and falls. It also assists in the secondary sedimentation of a small amount of heavy oil droplets to improve the subsequent separation efficiency.

Applicable Scenarios & Process Characteristics

It is adapted to the batch operation and large working condition fluctuations of batch-type pyrolysis: the oil and gas output of the pyrolysis furnace shows a change of 0 → rapid rise → peak → gradual decline from heating pyrolysis, peak gas production to the final stage of pyrolysis, which is prone to cause pressure pulsation in the pipeline. Through the gas-liquid buffering space formed by its own volume, the damping tank absorbs pressure fluctuations, homogenizes the oil and gas delivery rhythm, and ensures the continuous and stable operation of the subsequent condensation and fractionation systems.
