    生物脫硫係統的運行及控製?

    一起來詳細了解下91无码麻豆视频設備係統中生物脫硫係統的運行及控製吧!

    Let's learn more about the operation and control of biological desulfurization system in biogas equipment system!
    1、91无码麻豆视频從噴淋反應器的下端進入,穿過填料層後從頂部離開,進入後續處理階段,在91无码麻豆视频管道上應設有流量計,以隨時監測管道內的91无码麻豆视频流量,此外,在沼管道上還應安裝有91无码麻豆视频成份分析儀,以定時監測91无码麻豆视频中脫硫後91无码麻豆视频內的硫化氫含量和甲烷含量。
    1. Biogas enters from the lower end of the spray reactor, leaves from the top after passing through the filler layer and enters the subsequent treatment stage. A flowmeter shall be set on the biogas pipeline to monitor the biogas flow in the pipeline at any time. In addition, a biogas composition analyzer shall be installed on the biogas pipeline to monitor the hydrogen sulfide content and methane content in the biogas after desulfurization.
    2、噴淋培養液從曝氣反應器泵出經換熱器後至噴淋反應塔上部進入,在實現噴淋循環的同時,通過換熱器使係統中培養液維持在一定的溫度環境下。
    2. The spray culture liquid is pumped out of the aeration reactor through the heat exchanger to the upper part of the spray reaction tower. While realizing the spray cycle, the culture liquid in the system is maintained at a certain temperature environment through the heat exchanger.
    3.在調試及運行的期間,先確定一個適合的溫度值。如果溫度下降,啟動換熱器熱水端的管道泵以升高溫度。當溫度升高到設定值時,停止管道泵。
    3. During commissioning and operation, determine a suitable temperature value first. If the temperature drops, start the pipeline pump at the hot water end of the heat exchanger to increase the temperature. When the temperature rises to the set value, stop the pipeline pump.
    4、風機采用了變頻控製,經過培養液曝氣反應器壁麵上安裝的ORP(氧化還原電位計)來測定培養液之中的含氧量,並經過變頻器調節控製風機的出風量,以使培養液之中的含氧量控製於適當的範圍。
    4. The fan adopts frequency conversion control. The oxygen content in the culture medium is measured by ORP (redox potentiometer) installed on the wall of the culture medium aeration reactor, and the air output of the fan is adjusted and controlled by the frequency converter to control the oxygen content in the culture medium within an appropriate range.
    5、在培養基曝氣反應器壁上設置取樣口,人工采集培養基的pH值,判斷培養基中是否需要堿,堿的用量大小。通常來說,當終端產物為元素硫時,不需在培養基中加入堿。當終端產品為稀硫酸時,需要在培養基中加入堿,以保持培養基的中性要求。
    5. A sampling port is set on the wall of the medium aeration reactor to manually collect the pH value of the medium to judge whether alkali is needed in the medium and the amount of alkali. Generally speaking, when the end product is elemental sulfur, it is not necessary to add alkali to the culture medium. When the end product is dilute sulfuric acid, alkali needs to be added to the culture medium to maintain the neutral requirements of the culture medium.
    6、理想的操作模式是每天更換一部分培養基。培養基的來源可通過沼液後的過濾和稀釋進行調節,調節方式須經試驗確定。由於沼液原料不同,置換量也需要現場試驗後確定,一般數據為每天更換數量的1/20至1/30。排出係統外的培養液需經過沉澱,以便在排出多餘的培養液同時,從係統中帶走可能存在的單質硫等固體物質。不同的91无码麻豆视频液可能不相同,使用何種營養液,具體要求和數量盡量是在調試時解決這個問題。
    6. The ideal mode of operation is to change part of the medium every day. The source of culture medium can be adjusted by filtration and dilution after biogas slurry, and the adjustment method must be determined by test. Due to different biogas slurry raw materials, the replacement amount also needs to be determined after field test. The general data is 1 / 20 to 1 / 30 of the replacement amount per day. The culture solution discharged from the system needs to be precipitated to take away the possible solid substances such as elemental sulfur from the system while discharging the excess culture solution. Different biogas liquid may be different. The specific requirements and quantity of nutrient liquid to be used shall be solved during commissioning.
