Application field and working principle of spray tower

Spray towers have a wide range of applications in the industrial field, the following are some common application areas:

Waste gas treatment: Spray towers are often used for industrial waste gas treatment. By contacting the waste gas with water, the harmful substances in the waste gas are removed by using the cooling and washing effects of the water. The spray tower can be used to treat harmful substances such as sulfur dioxide, nitrogen oxides, and particulate matter to achieve the purpose of purifying exhaust gas.

Wastewater treatment: Spray towers can also be used to treat industrial wastewater. By contacting the wastewater with water, the harmful substances in the wastewater are removed by using the cooling and washing effects of the water. Spray towers can be used to treat harmful substances such as heavy metals and organic matter to achieve the purpose of purifying wastewater.

Gas purification: The spray tower can also be used for gas purification. By contacting the gas with water, the harmful substances in the gas can be removed by using the cooling and washing effect of the water. The spray tower can be used to treat industrial waste gas, tail gas and other gases to achieve the purpose of purifying the gas.

Wastewater Concentration: The spray tower can also be used for wastewater concentration. By contacting the wastewater with water, using the cooling and washing effect of the water, the harmful substances in the wastewater are removed and concentrated to a higher concentration. The spray tower can be used to treat high-concentration wastewater and improve the efficiency of wastewater treatment.

Exhaust gas recovery: The spray tower can also be used for exhaust gas recovery. By contacting the exhaust gas with water, the useful substances in the exhaust gas can be recycled by using the cooling and washing effect of the water. The spray tower can be used to recover useful gases such as nitrogen and oxygen in the waste gas.

The working principle of the spray tower is to remove harmful substances in the exhaust gas by contacting the exhaust gas with water and using the cooling and washing effect of the water. Specifically, the working principle of the spray tower can be divided into the following steps:

When the exhaust gas enters the spray tower, the water will come into contact with harmful substances such as particulate matter, sulfur dioxide, and nitrogen oxides in the exhaust gas. These harmful substances will be absorbed and dissolved by dissolved substances in water (such as alkaline substances) to form a solution.

Under the action of cooling, the harmful substances in the exhaust gas will be gradually absorbed by the dissolved substances in the water and form a solution. The dissolved substances in these solutions react with harmful substances in the exhaust gas, dissolve them and remove them.

Scrubbing means that the dissolved substances in the water react with the harmful substances in the exhaust gas to dissolve and remove them. This process can be achieved through different chemical reactions, such as acid-base reaction, redox reaction, etc.

After washing, the exhaust gas is filtered, dust-removed, etc., and finally discharged into the atmosphere. This can effectively purify the exhaust gas and reduce the impact on the environment.

It should be noted that the application fields & working principle of spray towers may vary due to different waste gas treatment equipment and processes. In practical application, it is also necessary to select the appropriate spray tower equipment according to the exhaust gas composition and treatment requirements, and carry out reasonable operation and maintenance to ensure the effect of exhaust gas treatment.
