PPH吸收塔的措施步驟:
(1)依據(jù)規(guī)劃任務(wù)和工藝要求,確認(rèn)規(guī)劃方案;
(2)針對物系及分離要求,選擇適宜填料;
(3)確認(rèn)塔徑、填料層高度等工藝尺度(考慮噴淋密度);
(4)核算塔高、及填料層的壓降;
預(yù)防措施
(1)科學(xué)選材,在低溫下嚴(yán)格禁止選用非低溫用鋼,選擇高抗蝕的資料。
(2)改良結(jié)構(gòu)規(guī)劃,結(jié)構(gòu)的規(guī)劃過程中,盡量選用油滑過度以削減構(gòu)件的應(yīng)力會集;設(shè)備運(yùn)行過程中,應(yīng)盡或許地避免頻頻的交變載荷,避免超溫運(yùn)作及局部過熱,防止出現(xiàn)水停滯,經(jīng)過熱處理對殘余應(yīng)力有效消除。
(3)強(qiáng)化原料性能的定期檢驗(yàn),對金屬構(gòu)件或設(shè)備所處的環(huán)境的腐蝕劑濃度實(shí)行嚴(yán)格檢測,并降低環(huán)境介質(zhì)的有效溫度等。
(4)改善介質(zhì)環(huán)境,削減氧化陽離子,將恰當(dāng)元素增加至資猜中,提升資料的抗蝕能力,選用表面防護(hù)方法。
以上關(guān)于PPH吸收塔所作的介紹,希望可以幫到您。
PPH absorption tower steps:
(1) Confirm the planning scheme according to the planning task and process requirements;
(2) According to the requirements of the system and separation, choose the appropriate filler;
(3) confirm the size of the tower, the height of the packing layer and other technological scales (considering the spray density);
(4) check tower height and pressure drop of packing layer;
preventive measure
(1) Scientific material selection, strictly prohibit the selection of non-low-temperature steel at low temperature, choose high corrosion resistance data.
(2) To improve the structural planning, in the process of structural planning, try to choose excessive oil slip to reduce the stress aggregation of members; In the process of equipment operation, frequent alternating load, overtemperature operation and local overheating should be avoided as far as possible, and water stagnation should be prevented. After heat treatment, residual stress can be effectively eliminated.
(3) To strengthen the regular inspection of raw material properties, to metal components or equipment in the environment of the corrosive concentration of the implementation of strict detection, and reduce the effective temperature of the environment medium.
(4) Improve the medium environment, reduce the oxidation cation, increase the appropriate elements to the information guessing, improve the corrosion resistance of the data, choose the surface protection method.
The above introduction of PPH absorber, I hope to help you.
