Knowledge of Installation and Maintenance of Waste Gas Treatment Tower
The exhaust gas treatment tower is a device that completes the absorption operation. It can be divided into three categories based on the shape of gas-liquid phase touch. The first type is plate tower, bubbling absorption tower, and mixing bubbling absorption tower where gas is dispersed in the liquid phase in the shape of bubbles; The second type is the ejector, Venturi tube and spray tower with liquid dispersed in the gas phase in the form of droplets; The third type is packed absorption towers and falling film absorption towers where the liquid moves in a film like manner and touches the gas phase. The activity method of gas-liquid two-phase flow inside the tower can be either counter flow or parallel flow. Generally, countercurrent operation is used, and the absorbent participates in top-down activity at the top of the tower, touching the gas moving from bottom to top. The liquid that absorbs the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.
In the era of increasingly developed industry, exhaust gas treatment towers play a crucial role. They can treat industrial exhaust gases and have a crucial effect on air purification. If there were no exhaust gas treatment towers, it's hard to imagine what a mess industry would become. So, how much do you know about the installation and maintenance of waste gas treatment towers?
Users carry out concrete foundation construction based on foundation data; The equipment should be installed on a concrete foundation that is more than 100mm above the ground; Supporting pipelines, valves, etc. should have independent support and cannot be fixed on tower equipment; During installation, attention should be paid to maintaining the equipment and avoiding damage to the body and exposed components. When connecting the tower flange with the external flange, the correct tightening method should be selected, and excessive force should not be applied to avoid cracking of the flange. Steel gaskets shall not be used for flange gaskets, and corrosion-resistant and oil resistant rubber gaskets can be used; After the equipment installation is completed, water is used for cyclic debugging, and it operates normally without any signs of running, emitting, dripping, leaking, or clogging.
In addition, to ensure the normal operation of the tower equipment, a dedicated person must be responsible for handling it. It is necessary to frequently check whether the fan and water pump are running normally, whether the spray pipe and air pipe are unobstructed, whether the liquid level in the storage tank is normal, whether the water replenishment float switch is normal, whether the gas-liquid concentration is within the regular range, etc. If problems are found, they should be dealt with in a timely manner.
Understanding the scientific installation and maintenance measures of waste gas treatment towers is beneficial without any harm, and can extend their lifespan and improve their functionality.
