1、高純二氧化碳主要用于電子工業(yè),用于配制其它特種混臺氣,在聚乙烯聚合反應(yīng)中則用作調(diào)節(jié)劑。
2、固態(tài)二氧化碳廣泛用于冷藏百奶制品、肉類、冷凍食品和其它轉(zhuǎn)運中易的食品,在許多工業(yè)加工中作為冷凍劑。
3、氣態(tài)二氧化碳用于碳化軟度飲料、食品保存、化學(xué)和食品加工過程的惰性保護、焊接氣體、植物生長劑。
4、液體二氧化碳用作致冷劑,飛機、和電子部件的低溫試驗,提高油井采收率,問橡膠磨光以及控制化學(xué)反應(yīng),也可用作滅火劑。

液體的儲存 liquid storage
液體二氧化碳的儲存屬于帶壓(壓力不低于0.8Mpa)儲存。儲存期間除壓力表、液位計、安全閥應(yīng)投入使用外,其他閥門應(yīng)處于關(guān)閉狀態(tài)。當(dāng)儲罐壓力超過2.1Mpa時,開啟V7排氣閥降壓。但應(yīng)注意:內(nèi)罐的壓力不得降至低于0.8Mpa,否則將引起液體二氧化碳轉(zhuǎn)變?yōu)楦杀?br>Liquid carbon dioxide storage with pressure (pressure not less than 0.8Mpa) storage. During the storage, the pressure gauge,level gauge, safety valve should be put into use, the other valves should be closed. When the tank pressure exceeds 2.1Mpa, open the V7 exhaust valve buck. However, it should be noted that the pressure inside the tank must not drop below 0.8Mpa, otherwise liquid carbon dioxide will be converted to dry ice.

充液的操作 filling operation
【標(biāo)題】
充液分為充液和補充充液。
充液的操作如下:
Filling fluid is divided into the first filling and filling fluid.
The first filling operation is as follows:
2.1.1 儲罐吹除置換干凈達到要求后,將充液管線與儲罐的充液接頭連接,液位計組合閥處于平衡狀態(tài)準(zhǔn)備充液。
After the tank blows off to replace the cleanliness meets the requirements, the filling liquid line is connected with the liquid filling joint of the tank, and the liquid level gauge combination valve is in an equilibrium state to be filled.
2.1.2充入與液體二氧化碳純度相同的氣體,使罐內(nèi)壓力達到0.8 Mpa以上,方可進行充液。 filled with the same purity of liquid carbon dioxide gas, the tank pressure reached 0.8 Mpa above, before filling.
2.1.3 將充液管線接通槽車,先開啟V5殘液閥,排出管線內(nèi)的雜質(zhì)氣體后,再開啟V1進液閥和V7排氣閥,V8液位計組合閥處于全開狀態(tài),顯示液位計讀數(shù)進行充液。
The filling liquid line connected tanker, first open the V5 raffinate valve, exhaust gas impurities within the pipeline, and then open the V1 inlet valve and V7 exhaust valve, V8 level gauge combination valve is fully open state, Display level meter readings are filled.
2.1.4 在充液過程中,當(dāng)液位計指示液位接近標(biāo)定值時,可間斷開啟V4充滿指示閥,如有液體噴出,應(yīng)立即停止充液,關(guān)閉V4充滿指示閥。
During the filling process, when the liquid level gauge indicates the liquid level approaches the calibration value, the V4 may be intermittently opened to indicate the valve. If any liquid is ejected, liquid filling should be stopped immediately and the V4 valve should be closed.
2.1.5關(guān)閉V1進液閥和V7排氣閥,打開V5殘液閥,拆下充液管線,充液結(jié)束。
補充充液的操作與充液的操作方法相似,不同點是補充充液時一開始就可以大量充液。
Close the V1 inlet valve and the V7 exhaust valve, open the V5 residual valve, remove the filling line, and fill with liquid.
The procedure for replenishing the priming solution is the same as for the first priming procedure, except that the priming solution can be replenished extensively from the beginning.
