沼氣生物脫硫裝置  化工廠脫硫設備工程原料預處理技術
Raw Material Pretreatment Technology for Desulfurization Equipment Engineering in Chemical Plant of Biogas Desulfurization Unit
根據不同的原料來源（秸稈、畜禽糞便和農業生產體系廢物），原料預處理技術可分為以下類型：
According to different sources of raw materials (straw, livestock manure and agricultural production system waste), raw material pretreatment technologies can be divided into the following types:
1.基于秸稈的原料預處理技術
1. Raw material pretreatment technology based on straw
以秸稈為主要原料的原料預處理技術主要包括物理方法（機械破碎、高溫熱解）、化學方法（酸預處理、堿預處理、臭氧處理）和物理和化學方法（物理和化學相結合）
The raw material pretreatment technology with straw as the main raw material mainly includes physical methods (mechanical crushing, high-temperature pyrolysis), chemical methods (acid pretreatment, alkali pretreatment, ozone treatment) and physical and chemical methods (physical and chemical combination)
2.基于畜禽糞便的原料預處理技術
2. Raw material pretreatment technology based on livestock manure
首先，糞便和其他廢物在均化槽中攪拌和均化。為了防止原料結塊和纖維物質對泵、閥門、外部設備、控制和其他下游設備造成問題，使用切碎機對原料進行均質
First, feces and other wastes are stirred and homogenized in the homogenizing tank. In order to prevent problems caused by raw material caking and fibrous substances to pumps, valves, external equipment, controls and other downstream equipment, shredders are used to homogenize raw materials

割斷。混合后的原料在混合罐中調整濃度和加熱溫度后，可以被送到發酵罐。
Cut. The mixed raw materials can be sent to the fermentation tank after the concentration and heating temperature are adjusted in the mixing tank.
3、基于農業生產體系廢棄物的原料預處理技術
3. Raw material pretreatment technology based on agricultural production system wastes
基于農業生產體系廢棄物的原料預處理技術是針對廚房和果蔬生物質廢棄物等生活垃圾的非均質、半流態特點，集除雜、破碎、均質、制漿為一體的一整套預處理技術。該技術可有效分離農業生產體系廢物和無機廢物，分離出的農業生產體系漿料可儲存在罐中，可通過厭氧發酵技術進一步處理,分類的無機物質，如塑料、廢紙和金屬，可以回收或送往垃圾填埋場。通過垃圾分類和無機物回收利用，改善材料的運輸和混合特性，確保處理系統持續穩定運行。結合農業生產體系物厭氧發酵生產沼氣等技術，廢物將“一個個分解"，充分體現低碳經濟和循環經濟發展模式下的理念創新。
Raw material pretreatment technology based on agricultural production system waste is a complete set of pretreatment technology integrating impurity removal, crushing, homogenization and pulping, aiming at the heterogeneous and semi fluid characteristics of domestic waste such as kitchen, fruit and vegetable biomass waste. This technology can effectively separate agricultural production system wastes and inorganic wastes. The separated agricultural production system slurry can be stored in tanks and further treated through anaerobic fermentation technology. Classified inorganic substances, such as plastics, waste paper and metals, can be recycled or sent to the landfill. Improve the transportation and mixing characteristics of materials through garbage classification and inorganic recycling to ensure the continuous and stable operation of the treatment system. In combination with technologies such as biogas production by anaerobic fermentation of agricultural production system, waste will be "decomposed one by one", fully reflecting the concept innovation under the development mode of low-carbon economy and circular economy.
