The Structure of The Damping tank

The damping tank is a vertical hollow pressure-bearing tank with an ultra-simplified internal structure, free of complex partitions or fillers. It features a hollow tank chamber as the core component, combined with three types of simple auxiliary structures configured on demand, and is designed to stabilize pressure, eliminate pulsation and achieve secondary heavy oil sedimentation. Its simplified structure is detailed as follows:

Core: Hollow vertical chamber

No internal partitions; the tank volume forms a buffer space to reduce the flow velocity of oil and gas, absorb pressure pulsation, and prevent coking in dead corners for easy cleaning.

Mandatory: Inlet baffle/diversion cylinder

Installed on the tank wall directly opposite the oil and gas inlet to prevent erosion of the tank wall by high-velocity airflow, guide the oil and gas to the middle and lower parts of the tank, extend the residence time and improve sedimentation efficiency.

Standard: Bottom oil-collecting conical base/diversion slope

The tank bottom is designed as a cone (60-90°) or a sloped surface to converge the settled heavy oil to the discharge port, avoiding accumulation and coking and ensuring smooth oil discharge.

Optional: Outlet mist baffle/baffle plate

Installed below the upper outlet of the tank, a single or double-layer horizontal plate that traps fine heavy oil mist droplets, only required for high-sulfur and high-heavy oil working conditions.

Supporting accessories: An oil discharge port is set at the tank bottom; a liquid level gauge interface is reserved at the middle and lower part of the side wall; a small hand hole is opened at the lower part for decoking and maintenance.

Design principles: No dead corners throughout, low airflow resistance and easy maintenance, adapted to the working conditions of pyrolysis oil and gas containing impurities and requiring regular decoking.
