沼氣生物脫硫裝置  化工廠脫硫設(shè)備工程原料預(yù)處理技術(shù)
Raw Material Pretreatment Technology for Desulfurization Equipment Engineering in Chemical Plant of Biogas Desulfurization Unit
根據(jù)不同的原料來(lái)源（秸稈、畜禽糞便和農(nóng)業(yè)生產(chǎn)體系廢物），原料預(yù)處理技術(shù)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(yù)處理技術(shù)
1. Raw material pretreatment technology based on straw
以秸稈為主要原料的原料預(yù)處理技術(shù)主要包括物理方法（機(jī)械破碎、高溫?zé)峤猓?、化學(xué)方法（酸預(yù)處理、堿預(yù)處理、臭氧處理）和物理和化學(xué)方法（物理和化學(xué)相結(jié)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(yù)處理技術(shù)
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(jié)塊和纖維物質(zhì)對(duì)泵、閥門、外部設(shè)備、控制和其他下游設(shè)備造成問(wèn)題，使用切碎機(jī)對(duì)原料進(jìn)行均質(zhì)
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(diào)整濃度和加熱溫度后，可以被送到發(fā)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(nóng)業(yè)生產(chǎn)體系廢棄物的原料預(yù)處理技術(shù)
3. Raw material pretreatment technology based on agricultural production system wastes
基于農(nóng)業(yè)生產(chǎn)體系廢棄物的原料預(yù)處理技術(shù)是針對(duì)廚房和果蔬生物質(zhì)廢棄物等生活垃圾的非均質(zhì)、半流態(tài)特點(diǎn)，集除雜、破碎、均質(zhì)、制漿為一體的一整套預(yù)處理技術(shù)。該技術(shù)可有效分離農(nóng)業(yè)生產(chǎn)體系廢物和無(wú)機(jī)廢物，分離出的農(nóng)業(yè)生產(chǎn)體系漿料可儲(chǔ)存在罐中，可通過(guò)厭氧發(fā)酵技術(shù)進(jìn)一步處理,分類的無(wú)機(jī)物質(zhì)，如塑料、廢紙和金屬，可以回收或送往垃圾填埋場(chǎng)。通過(guò)垃圾分類和無(wú)機(jī)物回收利用，改善材料的運(yùn)輸和混合特性，確保處理系統(tǒng)持續(xù)穩(wěn)定運(yùn)行。結(jié)合農(nóng)業(yè)生產(chǎn)體系物厭氧發(fā)酵生產(chǎn)沼氣等技術(shù)，廢物將“一個(gè)個(gè)分解"，充分體現(xiàn)低碳經(jīng)濟(jì)和循環(huán)經(jīng)濟(jì)發(fā)展模式下的理念創(chuàng)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.
