Triethylamine tail gas purification tower A equipment A device

Triethylamine tail gas purification tower A equipment A deviceThe triethylamine tail gas purification system consists of a suction hood, a pressure equalization box, a sand and dust separator, a purification tower, and a pipeline system. The triethylamine tail gas purification tower works through a fan under the control of an electrical control system, with the purification tower being the main equipment of the system.
1. Triethylamine exhaust gas purification equipment - suction hood
The suction hood and pipeline are made of fiberglass, and the pipeline system can be fixed to the columns of the factory building. The entire pipeline includes plug-in valves and fixing devices, and requires good sealing;
2. Triethylamine exhaust gas purification device - pressure equalization box
The function of the pressure equalization box is to evenly distribute the exhaust gases from various dust sources collected by the vacuum hood in the pipeline system, forming a low-speed upward airflow that enters the sand dust separator and the triethylamine tail gas purification tower, effectively and fully neutralizing with the phosphoric acid liquid (mist).
3. Triethylamine tail gas purification tower sand dust separator
The function of the sand and dust separator is to filter the exhaust gas entering the fan, separate and remove sand particles and other foreign objects from the exhaust gas, prevent foreign objects from entering the triethylamine tail gas purification equipment, and improve the system treatment effect.
4. Triethylamine tail gas purification equipment - purification tower
The triethylamine tail gas purification device is the main equipment of the triethylamine waste gas treatment system. There are spray, dehydration and other devices inside the tower, and separate neutralization and acid storage tanks at the bottom of the tower. The external circulating water pump, acid pump, pH controller and liquid level gauge are integrated.
5. Triethylamine exhaust gas purification device - fan
The fan is the power equipment of the entire system. The fan casing is made of corrosion-resistant fiberglass, and the impeller is made of a composite structure of carbon steel and fiberglass. The suction port is equipped with a coarse filter and a good shock absorber to reduce operating noise.

Due to the alkaline nature of triethylamine waste gas,Triethylamine tail gas purification tower A equipment A deviceUsing phosphoric acid to undergo neutralization reaction to generate triethylamine phosphate, achieving purification effect. The chemical equation is: (CH3CH), N+H, P0 (CH, CH) N · HPO (triethylamine phosphate).
Due to the high solubility of triethylamine in water, after practice, a dilute phosphoric acid solution of 2% to 4% in a spray state was selected as the neutralizing absorption solution, resulting in good treatment effect.
