Description

TECHNICAL FIELD

[0001] The utility model relates to chemical industry waste gas treatment technical field especially relates to a chemical industry waste gas cleaning device. BACKGROUND

[0002] Chemical industry waste gas is the collective term of various harmful gases generated in the chemical production process. These waste gas components are complex and diverse, often containing volatile organic compounds (such as benzene, toluene, xylene, etc.), acid gases (such as hydrogen chloride, sulfur dioxide, etc.), alkaline gases (such as ammonia), and some toxic and harmful inorganic substances (such as hydrogen sulfide, nitrogen oxides, etc.). Chemical industry waste gas has strong irritability, corrosivity and toxicity, not only poses a serious threat to human health, such as causing respiratory diseases, nervous system damage and even cancer, but also causes great damage to the environment, such as causing acid rain, destroying the ozone layer, and exacerbating the greenhouse effect. Due to the diversity of chemical production processes, the emission and composition of chemical industry waste gas will vary due to differences in production processes, raw materials and reaction conditions. In the field of chemical production, the generation of waste gas is inevitable, and effective cleaning and treatment of these chemical industry waste gas is a key link to protect the environment and ensure personnel health.

[0003] The traditional chemical industry waste gas cleaning device gradually exposes some significant problems in practical application. In the aspect of stirring, the common one-way stirring method has the problem of uneven stirring. Due to the limitations of one-way stirring, the contact between waste gas and cleaning liquid is not sufficient, resulting in poor cleaning effect and inability to completely remove harmful substances in waste gas. The composition of chemical industry waste gas is usually complex, containing various organic compounds, acidic or alkaline substances, etc. Single direction stirring cannot cope with this complexity, so that some waste gas components cannot fully react with the cleaning liquid, thereby reducing the overall processing capacity of the cleaning device.

[0004] Therefore, we propose a chemical industry waste gas cleaning device. INVENTION CONTENTS
