不銹鋼反應釜內物料溫度檢測及控制方法

不銹(xiu)鋼(gang)反(fan)應(ying)釜的(de)工作原理就是兩(liang)種(zhong)或兩(liang)種(zhong)以上介質在一定(ding)的(de)溫度(du)下伴隨攪(jiao)拌(ban)進行某種(zhong)反(fan)應(ying),如(ru)不銹(xiu)鋼(gang)反(fan)應(ying)釜內部物(wu)料(liao)(liao)的(de)溫度(du)控制(zhi)不好,會大幅度(du)降低生產率甚至報廢整(zheng)個釜內物(wu)料(liao)(liao),那么如(ru)何檢測(ce)不銹(xiu)鋼(gang)反(fan)應(ying)釜內物(wu)料(liao)(liao)溫度(du)并且對其加以控制(zhi)呢?

檢測方法:可(ke)以(yi)用PT100溫度計(ji),用密封的不(bu)銹(xiu)鋼管子(zi)(zi)插(cha)入斧內,管子(zi)(zi)里加進去一些導熱油(you),把(ba)溫度計(ji)塞到(dao)導熱油(you)以(yi)下就可(ke)以(yi),不(bu)會有太大的誤差的。

溫度過高的控制

1、停(ting)止加熱:通過電(dian)器(qi)(qi)控(kong)制箱上的溫(wen)度顯示儀表及報(bao)警(jing)器(qi)(qi)可方便、快捷地(di)判斷出不銹鋼反應釜內部物料的溫(wen)度情況,當溫(wen)度過高時,電(dian)器(qi)(qi)控(kong)制器(qi)(qi)按設定的程序自動地(di)停(ting)止某組(zu)電(dian)加熱器(qi)(qi)的工作,將溫(wen)度保持在(zai)恒定的范圍內。

2、啟動釜(fu)內的(de)(de)冷(leng)(leng)卻(que)(que)盤管:釜(fu)內的(de)(de)冷(leng)(leng)卻(que)(que)盤管一般作為(wei)冷(leng)(leng)卻(que)(que)用(yong),如當(dang)檢測到不銹鋼反(fan)應釜(fu)內部(bu)(bu)物料的(de)(de)溫度(du)可能很高時(shi),及時(shi)啟用(yong)內部(bu)(bu)冷(leng)(leng)卻(que)(que)盤管,并(bing)加大冷(leng)(leng)卻(que)(que)水的(de)(de)流量,及時(shi)有效地降(jiang)低(di)不銹鋼反(fan)應釜(fu)內部(bu)(bu)物料的(de)(de)溫度(du)。

3、持續攪拌。

溫度過低時的控制

啟動剩(sheng)余(yu)加熱器(qi):通(tong)常情況下(xia),在不銹鋼反應(ying)的設計與制作(zuo)中(zhong)會(hui)(hui)為用(yong)戶考慮到,生(sheng)產過程(cheng)會(hui)(hui)更換(huan)不同(tong)(tong)的物料(liao),不同(tong)(tong)物料(liao)的理化(hua)特性(xing)不同(tong)(tong),加熱效(xiao)果也不同(tong)(tong),因(yin)此會(hui)(hui)相應(ying)適(shi)當(dang)增加加熱器(qi)的功率,根據不同(tong)(tong)的物料(liao)進行選擇,當(dang)溫度過度低時(shi),啟用(yong)剩(sheng)余(yu)加熱器(qi)便可。

The working principle of stainless steel reactor is two or more than two kinds of medium at a certain temperature with stirring for a reaction, such as stainless steel reactor internal material temperature control is not good, will greatly reduce the productivity and scrap materials the kettle, so how to detect the temperature of materials of stainless steel reactor and to control them.?

Test method: you can use the PT100 thermometer, stainless steel pipe sealing insert axe, the add in some oil, put the thermometer into the heat conduction oil below it, won't have too big error.

Control the temperature too high

1、Stop heating: according to the electrical control box on the temperature display instrument and alarm can be convenient, quick to judge the temperature stainless steel reactor internal material, when the temperature is too high, electric controller programmed automatically stop a group of electric heater, the temperature is maintained at a constant range.

2、Start the cooling coil in the cauldron: cooling coil reactor is generally used as cooling, such as when the stainless steel reactor internal temperature of the material may be high, to enable the internal cooling coil, and to increase the flow of cooling water, timely and effectively reduce the stainless steel reactor internal temperature of the material.

3、Continuous mixing

Control when the temperature is too low.

Start the remaining heater: under normal circumstances, in the design and manufacture of stainless steel reaction will be considered for the user to be replaced, the production process of different materials, different materials have different physical and chemical properties, the heating effect is different, so will be appropriate to increase the power of the heater, according to different material choice, when the temperature is too low when enabled, the remaining heater can.
