[0002] With the progress of industrialization and urbanization, the corresponding sewage and sludge production also increases rapidly. The sludge produced by sewage treatment is rich in organic matter and contains a certain amount of heavy metals, pathogens and other harmful substances. The secondary pollution of sludge is serious. "Drying + incineration" is an ideal scheme for sludge treatment and disposal in China at present. A large amount of tail gas is generated during the deep dewatering and drying treatment of sludge in sewage treatment plants. Direct discharge of tail gas into the atmosphere will pollute the environment, which does not conform to the environmental protection theme of "green water and green mountains are golden mountains and silver mountains" advocated by China at present. Further treatment of tail gas is needed.

[0003] The dust-containing tail gas is sucked into the device by the suction fan. When the liquid is sprayed, the dust inside the tail gas is humidified and clumped.

[0004] The existing equipment has the problem that when it is used, the dust-containing tail gas may contain sticky dust. After spraying liquid for dust removal, the sticky dust and the liquid form a paste-like substance after mixing, which adheres to the nozzle outlet, causing the atomization effect to decrease, and even completely blocking, which needs to be cleaned constantly, affecting work efficiency. Therefore, we propose a new type sludge drying tail gas dust removal device. UTILITY MODEL CONTENTS
