Technical Field

[0002] By using specially designed solid waste sludge drying waste gas recovery equipment, we can not only significantly improve energy utilization efficiency and greatly reduce energy consumption, but also significantly reduce environmental pollution. This device effectively collects and treats the waste gas generated during the sludge drying process. This device purifies the harmful substances in the waste gas through the waste gas treatment system to ensure that the discharged waste gas meets environmental protection standards, effectively reducing pollution to the environment. In this way, the solid waste sludge drying process can not only be completed efficiently and economically, but also play a positive role in environmental protection and sustainable development. This green, environmentally friendly and sustainable development model is of great significance to promoting a virtuous cycle of environmental protection and economic and social development.

[0003] The existing solid waste sludge drying waste gas recovery device mainly focuses on the collection and treatment of waste gas, and can indeed effectively concentrate and manage the waste gas generated in the sludge drying process, thereby preventing the pollution caused by the direct discharge of these waste gases into the environment. However, although this device performs well in waste gas management, it has a significant problem: it is unable to effectively recover and reuse the heat contained in the waste gas. In the process of sludge drying, the waste gas usually contains a large amount of thermal energy, which will be directly discharged into the atmosphere in the form of waste heat, which not only causes energy waste, but more importantly, because this part of the heat energy is not reused, the overall energy utilization efficiency of the device is not high, which increases production costs. At the same time, it is also contrary to the current trend of pursuing green, environmental protection and sustainable development. Utility Model Content
