隨著技術(shù)的進(jìn)步，現(xiàn)在不銹鋼反應(yīng)釜爆破的機(jī)率已經(jīng)大大減小了，但這不意味著分解爆破就不發(fā)生了，實(shí)際上如果生產(chǎn)中還是存在著嚴(yán)重不當(dāng)?shù)氖褂貌僮鬟€是會帶來分解爆破的危險(xiǎn)，比如催化劑用量過多或投料速度過快導(dǎo)致瞬間溫度上升速度太快等均會引起不銹鋼反應(yīng)釜分解爆破。因此，在不銹鋼反應(yīng)釜安全生產(chǎn)中，一定要嚴(yán)格遵守“不銹鋼反應(yīng)釜使用注意事項(xiàng)，本文將給大家介紹下不銹鋼反應(yīng)釜爆破的原因及一些使用的注意事項(xiàng)。
不銹鋼反應(yīng)釜爆破原因及處理辦法
1、反應(yīng)釜中帶入機(jī)械雜質(zhì)，產(chǎn)生局部摩擦發(fā)熱導(dǎo)致反應(yīng)釜分解爆破。
處理方法：注意檢修時(shí)不要掉入機(jī)械雜質(zhì)。
2、軸承組件磨損發(fā)熱，產(chǎn)生過熱后溫度升高導(dǎo)致反應(yīng)釜分解爆破。
處理方法：嚴(yán)格檢查備件質(zhì)量，提高檢修質(zhì)量。
3、攪拌器槳葉與釜壁摩擦產(chǎn)生局部過熱導(dǎo)致不銹鋼反應(yīng)釜分解爆破。
處理方法：提高檢修質(zhì)量和備件質(zhì)量。
4、催化劑系統(tǒng)儀表自控或催化劑泵操作失靈導(dǎo)致反應(yīng)釜分解爆破。
處理方法：檢修、調(diào)試儀表，達(dá)到準(zhǔn)確、靈敏。
5、催化劑用量過多或投料速度過快，瞬間溫度上升速度太快導(dǎo)致分解爆破。
處理方法：嚴(yán)格控制催化劑用量，加料應(yīng)均勻。
6、工藝系統(tǒng)內(nèi)氣體氧含量增高導(dǎo)致反應(yīng)釜分解爆破。通常應(yīng)不大于1ppm
處理方法：嚴(yán)格控制工藝系統(tǒng)中的含氧量。
不銹鋼反應(yīng)釜使用注意
（一）反應(yīng)釜開車前
1、檢查釜內(nèi)、攪拌器、轉(zhuǎn)動部分、附屬設(shè)備、指示儀表、安全閥、管路及閥門是否符合安全要求。
2、檢查水、電、氣是否符合安全要求。
（二）反應(yīng)釜開車中
1、加料前應(yīng)先開反應(yīng)釜的攪拌器，無雜音且正常時(shí)，將料加到反應(yīng)釜內(nèi)，加料數(shù)量不得很過工藝要求。
2、打開蒸氣閥前，先開回氣閥，后開進(jìn)氣閥。打開蒸氣閥應(yīng)緩慢，使之對夾套預(yù)熱，逐步升壓，夾套內(nèi)壓力不準(zhǔn)很過規(guī)定值。
3、蒸氣閥門和冷卻閥門不能同時(shí)啟動，蒸氣管路過氣時(shí)不準(zhǔn)錘擊和碰撞。
4、開冷卻水閥門時(shí)，先開回水閥，后開進(jìn)水閥。冷卻水壓力不得低于0．1兆帕，也不準(zhǔn)高于0．2兆帕。
5、水環(huán)式真空泵，要先開泵后給水，停泵時(shí)，先停泵后停水，并應(yīng)排除泵內(nèi)積水。
6、隨時(shí)檢查反應(yīng)釜運(yùn)轉(zhuǎn)情況，發(fā)現(xiàn)異常應(yīng)停車檢修。
7、清洗鈦環(huán)氧（搪瓷）反應(yīng)釜時(shí)，不準(zhǔn)用堿水刷反應(yīng)釜，注意不要損壞搪瓷。
（三）反應(yīng)釜停車后
1、停止攪拌，切斷電源，關(guān)閉各種閥門。
2、鏟鍋時(shí)必須切斷攪拌機(jī)電源，懸掛警示牌，并設(shè)人監(jiān)護(hù)。
3、反應(yīng)釜必須按壓力容器要求進(jìn)行定期技術(shù)檢驗(yàn)，檢驗(yàn)不合格，不得開車運(yùn)行。
but this does not mean that the decomposition of blasting is not changed, in fact if the production or the existence of serious improper use or be dangerous decomposition blasting, such as the excessive amount of catalyst or feeding speed causes the instantaneous temperature rises too fast, will cause the stainless steel reactor decomposition blast. Therefore, in the stainless steel reactor safety in production, must strictly abide by the "stainless steel reactor use pay attention to item, this article will introduce the reason of stainless steel reactor blasting and some matters needing attention for everyone. The reaction kettle blasting of
stainless steel and treatment methods Into the mechanical impurity
1, reaction kettle, local friction fever causes the reactor decomposition blast.
processing method: pay attention to maintenance do not fall into the mechanical impurities.
2, bearing assembly wear fever, elevated temperatures lead to overheating reactor decomposition blast.
processing methods: strictly check the parts quality, improve the quality of maintenance.
3, a blade and vessel wall friction to generate local overheating stainless steel reactor decomposition blast. The
approach: improve the quality of maintenance and spare parts quality.
4, catalyst system instrumentation or catalyst pump operation failure causes the reactor decomposition blast. The
approach: maintenance, debugging instrument, to achieve accurate, sensitive.
5, excessive amount of catalyst or the feeding speed is too fast, instantaneous temperature rise too fast cause decomposition of blasting.
processing methods: strictly control the amount of catalyst, the feeding should be uniform. Increased oxygen content
6, craft system lead to reactor decomposition blast. Usually should not be greater than 1ppm
processing method: strict control of the oxygen content in the process system.
stainless steel reactor using note
(a) reactor before driving
1, check the kettle, blender, rotating parts, ancillary equipment, instrumentation, safety valves, piping and valves whether to meet the safety requirements.
2, check the water, electricity, gas or meet safety requirements.
(two) stirrer reactor should first open reactor drive
1, feeding, no noise and normal, the material is added to the reaction kettle, feeding amount shall not exceed the process requirements.
2, open the steam valve, first open the valve, open the inlet valve. Open the steam valve to be slow, so that the jacket preheating, the boost phase, the inside of the jacket pressure must not exceed the specified value.
3, the steam valve and cooling valve cannot be active at the same time, steam pipeline gas no hammer and collision.
4, open cooling water valve, first open the return valve, open the water inlet valve. Cooling water pressure shall not be less than 0.1 MPa, no higher than 0.2 mpa.
5, the water ring vacuum pump, to open the pump water, when the pump stops, the first stop after pump water, and should be excluded in water pump.
6, always check the reactor operation, unusual should be stopped for maintenance.
7, cleaning titanium epoxy (enamel) reactor, do not use alkaline brush reactor, taking care not to damage the enamel.
(three)
1 reactor after parking, stop stirring, cut off the power supply, close the valve.
2, shovel pot must cut off the mixer power, suspension of warning signs, and guardianship.
3, the reactor must be regular inspection on pressure vessels, inspection is not qualified, shall not drive operation.
