隨著技術的進步，現(xiàn)在不銹鋼反應釜爆破的機率已經(jīng)大大減小了，但這不意味著分解爆破就不發(fā)生了，實際上如果生產(chǎn)中還是存在著嚴重不當?shù)氖褂貌僮鬟€是會帶來分解爆破的危險，比如催化劑用量過多或投料速度過快導致瞬間溫度上升速度太快等均會引起不銹鋼反應釜分解爆破。因此，在不銹鋼反應釜安全生產(chǎn)中，一定要嚴格遵守“不銹鋼反應釜使用注意事項，本文將給大家介紹下不銹鋼反應釜爆破的原因及一些使用的注意事項。

不銹鋼反應釜爆破原因及處理辦法

1、反應釜中帶入機械雜質，產(chǎn)生局部摩擦發(fā)熱導致反應釜分解爆破。

處理方法：注意檢修時不要掉入機械雜質。

2、軸承組件磨損發(fā)熱，產(chǎn)生過熱后溫度升高導致反應釜分解爆破。

處理方法：嚴格檢查備件質量，提高檢修質量。

3、攪拌器槳葉與釜壁摩擦產(chǎn)生局部過熱導致不銹鋼反應釜分解爆破。

處理方法：提高檢修質量和備件質量。

4、催化劑系統(tǒng)儀表自控或催化劑泵操作失靈導致反應釜分解爆破。

處理方法：檢修、調試儀表，達到準確、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致分解爆破。

處理方法：嚴格控制催化劑用量，加料應均勻。

6、工藝系統(tǒng)內氣體氧含量增高導致反應釜分解爆破。通常應不大于1ppm

處理方法：嚴格控制工藝系統(tǒng)中的含氧量。

不銹鋼反應釜使用注意

（一）反應釜開車前

1、檢查釜內、攪拌器、轉動部分、附屬設備、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）反應釜開車中

1、加料前應先開反應釜的攪拌器，無雜音且正常時，將料加到反應釜內，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，后開進氣閥。打開蒸氣閥應緩慢，使之對夾套預熱，逐步升壓，夾套內壓力不準很過規(guī)定值。

3、蒸氣閥門和冷卻閥門不能同時啟動，蒸氣管路過氣時不準錘擊和碰撞。

4、開冷卻水閥門時，先開回水閥，后開進水閥。冷卻水壓力不得低于0．1兆帕，也不準高于0．2兆帕。

5、水環(huán)式真空泵，要先開泵后給水，停泵時，先停泵后停水，并應排除泵內積水。

6、隨時檢查反應釜運轉情況，發(fā)現(xiàn)異常應停車檢修。

7、清洗鈦環(huán)氧（搪瓷）反應釜時，不準用堿水刷反應釜，注意不要損壞搪瓷。

（三）反應釜停車后

1、停止攪拌，切斷電源，關閉各種閥門。

2、鏟鍋時必須切斷攪拌機電源，懸掛警示牌，并設人監(jiān)護。

3、反應釜必須按壓力容器要求進行定期技術檢驗，檢驗不合格，不得開車運行。

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.
