Production of desulfurization tower pressure vessel

Production of desulfurization tower pressure vessel，The process equipment for cylindrical welding structures consists of a cylinder body, a head (or cap), and a support. It is a non-standard equipment designed and manufactured specifically for a certain production process requirement. A tower is an upright equipment used for distillation, purification, absorption, distillation and other chemical unit operations, widely used for mass and heat transfer between gas-liquid and liquid-liquid phases. According to the internal structure classification, towers can be divided into plate towers and packed towers. If the interior of a container only contains materials without undergoing chemical reactions or other physical or chemical processes, and there are no facilities or only simple auxiliary structures, it is also called a tank. Containers are classified into two types based on their type: vertical (with a vertical axis) and horizontal (with a horizontal axis). Most towers belong to pressure vessels.

There are a certain number of trays in the plate tower, and gas is transferred to the liquid layer on the trays in the form of bubbles or jets. There is a certain height of packing inside the packed tower, and the liquid flows down along the packing from top to bottom, while the gas contacts the liquid film in reverse flow from bottom to top for material transfer. Commonly used in distillation, water absorption, extraction and other operations.

Plate tower

According to the gas-liquid operation state, it can be divided into bubble tray, such as float valve tray, bubble cap tray, sieve tray, and jet tray, such as mesh and tongue shaped tray. It can also be divided into overflow tray (bubble cap, etc.) and flow-through tray (flow-through grating and flow-through sieve plate, etc.) based on the presence or absence of downcomers.

Chemical environmental protection washing towerIn the deviceA certain height of packing is installed, and the liquid flows down along the packing from top to bottom, while the gas contacts the liquid film in reverse flow from bottom to top for material transfer. Commonly used in distillation, water absorption, extraction and other operations. According to structural characteristics, it can be divided into random packing (step ring, flower wreath packing, multi-faceted hollow ball, saddle ring packing, ball ring and other granular packing) and regular packing (wire mesh corrugated packing and orifice plate corrugated plate packing), as well as tower internals packing support and pressure grid.

Lifting tower equipmentPrecautions：

Equipment lifting should take off and land smoothly without being impacted;

The installation should be stable and firm, and the tower body should be vertical. In windy areas, the tower body should be reinforced;

The pipeline connected to the equipment should avoid all its weight acting on the connecting pipe of the equipment, and the outlet pipe at the top of the tower should be fixed;

Suggest installing compensators for takeover and pipeline connections;

When driving, the absorption liquid water pump should be started first, the fan should be turned on, and it should run normally before entering the system;

During system operation, the flow rate of the water pump should be adjusted to prevent excessive or insufficient flow from affecting the effectiveness of use;

Pay attention to the water level at the bottom of the tower to prevent liquid from entering the air duct;

Prevent debris from entering the tower and blocking channels and pipelines;

If the medium has viscosity or sediment attached to the tower, causing a decrease in treatment effect, the flange can be disassembled to clean the blades.
