摘要：【中文】本发明提供了一种污泥处理系统及方法，涉及污泥处理技术领域，污泥处理系统包括焚烧炉、污泥干化装置和气体处理装置；污泥干化装置具有进料口，用于向污泥干化装置中输送湿污泥；焚烧炉的第一排气口与污泥干化装置连接，用于向污泥干化装置中输送烟气；污泥干化装置的出料口与焚烧炉连接，用于将干化后的污泥送入焚烧炉内焚烧；污泥干化装置的出风口与气体处理装置连接，气体处理装置的出口与所述焚烧炉连接。利用烟气的热量将湿污泥干化处理为干污泥，干污泥在焚烧炉焚烧处理，干化过程中产生的尾气经气体处理装置处理后作为二次风返回焚烧炉内焚烧，防止尾气中的有毒有害物质直接排入大气中污染环境，且尾气余热再利用，节约能源。 【EN】The invention provides a sludge treatment system and a method, which relate to the technical field of sludge treatment, wherein the sludge treatment system comprises an incinerator, a sludge drying device and a gas treatment device; the sludge drying device is provided with a feed port and is used for conveying wet sludge into the sludge drying device; a first exhaust port of the incinerator is connected with the sludge drying device and used for conveying flue gas into the sludge drying device; the discharge port of the sludge drying device is connected with the incinerator and is used for feeding dried sludge into the incinerator for incineration; the air outlet of the sludge drying device is connected with the gas treatment device, and the outlet of the gas treatment device is connected with the incinerator. The wet sludge is dried by utilizing the heat of the flue gas to be dry sludge, the dry sludge is incinerated in the incinerator, the tail gas generated in the drying process is treated by the gas treatment device and then returns to the incinerator as secondary air to be incinerated, the toxic and harmful substances in the tail gas are prevented from being directly discharged into the atmosphere to pollute the environment, and the waste heat of the tail gas is recycled, so that the energy is saved.
