二氧化碳儲罐的長處
二氧化碳儲罐是儲存液態(tài)二氧化碳介質(zhì)的儲存壓力容器。
二氧化碳儲罐內(nèi)膽原料選用16MnDR,二氧化碳罐外膽原料為Q245R或者Q345R。
二氧化碳罐選用“組合、安全體系閥”運(yùn)用兩組安全閥一起作業(yè),在安全閥定時(shí)校驗(yàn)時(shí)可關(guān)閉一側(cè),另一側(cè)持續(xù)作業(yè),保證二氧化碳罐的安全運(yùn)轉(zhuǎn)。
二氧化碳罐選用熱態(tài)下的珠光砂為絕熱材料并抽真空,公司以共同的技術(shù)保證質(zhì)量,以達(dá)到絕熱作用。
二氧化碳罐具有運(yùn)用壽命長、構(gòu)造緊湊、占地面積少、集中控制、操作和維修便利等特色。
二氧化碳罐的規(guī)劃壓力為2.2MPa

液體的排放 liquid discharge
【產(chǎn)品詳情圖片】
2.4.1液體二氧化碳的正常排放是在儲罐增壓后,開啟V2排液閥,V3回氣閥,液體二氧化碳便流入汽化器汽化,供使用點(diǎn)使用。
The normal discharge of liquid carbon dioxide is after pressurization of the tank, open the V2 drain valve, V3 return valve, the liquid carbon dioxide will flow into the vaporizer vaporization for use point.
2.4.2為滿足排液過程的穩(wěn)定壓力,應(yīng)按“儲罐的增壓”操作方法進(jìn)行增壓。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".

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(jì)、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(shí),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.

儲罐的增壓 Tank pressurization
【產(chǎn)品詳情圖片】
當(dāng)儲罐向外供液又需要穩(wěn)定排液壓力時(shí),可利用汽化器(另外配備)進(jìn)行增壓。其操作過程如下:
The carburetor (available separately) can be used for boosting when the reservoir is supplied externally and requires stable discharge pressure. The operation is as follows:
2.3.1開啟V2排液閥,使液體二氧化碳汽化器汽化,開啟V3回氣閥(根據(jù)用戶回氣管路的設(shè)置,V3回氣閥可置于常開狀態(tài))從汽化器分流出來的氣體返回儲罐上部,使儲罐內(nèi)增壓。
Open the V2 drain valve to vaporize the liquid carbon dioxide vaporizer and open the V3 return valve (the V3 return valve can be normally open depending on the return air line of the user). The gas diverted from the vaporizer returns to the upper part of the tank , So that the pressure tank.
2.3.2當(dāng)儲罐內(nèi)壓力達(dá)到2.1Mpa時(shí),可暫時(shí)關(guān)閉V3回氣閥。
When the tank pressure reaches 2.1Mpa, the valve can be temporarily closed V3 return gas valve.
2.3.3排液過程中,可通過控制V3回氣閥的開度,使增壓能力維持在壓力穩(wěn)定的水平。
During drainage, the degree of pressurization can be maintained at a pressure-stable level by controlling the opening of the V3 return valve.
