The three kinds of process of sludge dryer refer to solar drying process, paddle heating drying process and high temperature wet oxidation process. The following Chengxiang technical personnel for you to briefly talk about the three kinds of sludge dryer process. 1. High-temperature wet oxidation process The so-called high-temperature wet oxidation process refers to the sludge and pure oxygen at the same time into the required temperature and pressure of the reaction vessel, pure oxygen in the high temperature, high pressure conditions, do not need to use the catalyst can be most of the organic matter oxidation, the remaining small portion of the sludge, can be dewatered through the mechanical way, drying, so as to achieve the purpose of drying, the process applies to the non-agricultural occasions, but can be used as a raw material for construction of secondary dryer. But it can be used as raw materials for construction for secondary utilization. 2. Paddle heating and drying process The so-called paddle heating and drying process refers to the use of heating and drying system to achieve the purpose of drying, this process in the structure of the main dryer, sludge feeder, auxiliary heat source, air supply system, heat recovery device, dust control, ash discharge, control system and other devices. 3. Solar drying process The so-called solar drying process refers to the use of solar energy will be dewatered sludge evaporation, through the evaporation can be obtained 60 ~ 80% of the dried sludge, at the same time, in the operation of the process, but also through the use of mixing wheels will be turned over the sludge flat on the floor, but also through the increase in the forced ventilation to improve the efficiency of evaporation. In general, this solar drying process has a simple process design, low investment and operating costs, and is more suitable for those users who have lower sludge production requirements and need long-term storage.
