Description

TECHNICAL FIELD

[0002] Desulfurization refers to the removal of sulfur from fuel before combustion and the desulfurization process before flue gas emission, which is one of the important technical measures to prevent air pollution. Currently, there are three methods of desulfurization: before combustion, during combustion, and after combustion. With the development of industry and the improvement of people's living standards, the demand for energy is increasing, and SO2 in flue gas has become the main cause of air pollution. Reducing SO2 pollution has become a top priority in air environmental management. Atmospheric desulfurization equipment is a kind of auxiliary equipment that removes sulfur oxides from flue gas or industrial waste gas generated during the combustion of fossil fuels to control acid rain and sulfur dioxide pollution. It is widely used in the field of air purification.

When the heat exchange box needs to be checked and repaired, it needs to be completely disassembled, which is time-consuming and labor-intensive. In addition, the inner wall of the desulfurization chamber in the desulfurization tank will adhere to dirt after a long period of operation, which will affect the desulfurization effect. However, the application also has some defects, such as the heat exchange box and the sliding plate being connected and not having a limiting and fixing mechanism, which can cause the heat exchange box and the sliding plate to move during use. In addition, the application does not have a filtering mechanism for the liquid outlet, and the waste liquid after the gas desulfurization reaction contains chemical impurities, which can pollute the environment. Therefore, an atmospheric desulfurization device for environmental protection engineering is proposed to solve the above technical problems. UTILITY MODEL CONTENTS
