Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, and more specifically, to a coke oven tail gas treatment mechanism. Background Art

[0002] The coke oven tail gas treatment mechanism is an environmental protection equipment specially used to treat the tail gas generated during the coking process. These tail gases contain a large amount of harmful substances, such as carbon monoxide, carbon dioxide, sulfide, nitrogen oxides and particulate matter, which cause serious pollution to the environment.

[0003] In the existing technology, firstly, the harmful gases and particulate matter in the exhaust gas of some devices may not be effectively removed, resulting in reduced purification efficiency. The coarse pollutants in the exhaust gas may damage the subsequent filter bags or other treatment components, shortening the service life of the equipment. Secondly, the filter bags in some devices may be deformed or damaged, thereby reducing the filtering effect. The filter bags may swing under the action of airflow, resulting in unstable exhaust gas treatment and affecting the overall treatment effect. Frequent filter bag replacement and maintenance will increase operating costs. Finally, some devices may shift or fall off under the action of airflow, affecting the normal operation of the entire treatment system. The unstable connection between the filter bag and the treatment tank may lead to reduced sealing and exhaust gas leakage, causing environmental pollution, which may make the filter bag installation difficult and increase installation time and labor intensity.
