儲油罐機(jī)械清洗技術(shù)是將被清洗儲罐底部具有流動性的油品移送至接收油罐，將清洗油供給罐中的油品經(jīng)加溫加壓后通過清洗機(jī)攪拌、溶解罐內(nèi)剩余凝固油，經(jīng)過濾器清除雜質(zhì)后移送至接收油罐，比較后用溫水對儲罐內(nèi)各部位進(jìn)行循環(huán)清洗，以達(dá)到罐內(nèi)動火條件。在清洗過程中持續(xù)注人惰性氣體至被清洗儲罐，從而使其內(nèi)部氧氣濃度始終保持在8VoL%以下，防止爆炸等危險的發(fā)生;配備氧氣及可燃?xì)怏w檢測裝置，時刻監(jiān)測被清洗儲罐內(nèi)的氧氣及可燃?xì)怏w濃度，確保機(jī)械清洗作業(yè)安全運行。
Mechanical cleaning technology of oil tank will be cleaning the bottom of the tank is transferred to the mobility of the oil receiving tank, cleaning oil supply tank in oil by heating and pressurizing by cleaning machine stirring and dissolving tank residual oil after solidification, filter to remove impurities after transferred to the receiving tank, at the end of each part of the storage tank for cleaning cycle with warm water, in order to achieve the conditions of hot pot. Continuous injection of inert gas to the tank to be cleaned in the cleaning process, so that the internal oxygen concentration remained below 8VoL%, to prevent the occurrence of explosion danger; equipped with oxygen and combustible gas detection device, time monitoring of cleaning oxygen and combustible gas in the tank concentration, to ensure safe operation of mechanical cleaning.
清洗流程1設(shè)備安裝
Cleaning process 1 equipment installation
采用輕型管線及閥門快速完成設(shè)備的安裝及管線的連接，并測試系統(tǒng)整體嚴(yán)密性;
Use light pipeline and valve to quickly complete the installation of the equipment and connection of the pipeline, and test the overall tightness of the system.
2油移送
2 oil transfer
通過移送模塊將被清洗油罐中具有流動性的油品移送至接收油罐;
The flow of oil in the oil tank is transferred to the receiving oil tank through the transfer module.
3同種油清洗
3 the same kind of oil cleaning
清洗模塊將清洗油供給罐中的油品經(jīng)加溫、加壓后，通過設(shè)置在被清洗儲罐單盤或罐側(cè)壁檢修孔上的清洗機(jī)對被清洗儲罐內(nèi)部凝固油進(jìn)行擊碎、溶解，使其具有較好的流動性，并通過移送模塊過濾后移送至接收油罐;
The cleaning module will clean the oil supply tank in oil by heating and pressurizing, the cleaning machine is arranged in the tank wall of the tank or a single disk access hole on the break, the tank cleaning oil solidification dissolved, which has good fluidity, and through the transfer of the filtered transferred to the receiving module oil tank;
4溫水清洗
4 warm water cleaning
由清洗模塊對預(yù)先加人到油水分離模塊中的清水進(jìn)行加溫、加壓后，通過清洗機(jī)清洗儲罐內(nèi)各部位，利用油水分離模塊分離溫水清洗循環(huán)過程中的油水混合物，分離出來的油品由回收泵移送至接收油罐，分離出來的清水繼續(xù)進(jìn)行溫水清洗循環(huán)作業(yè)。
To add to the advance of oil-water separation module in water for heating and pressurizing by cleaning module, through various parts of machine cleaning tank, the oil-water oil-water separation module separation warm water cleaning cycle in the mixture, the separated oil transferred from the pump to the receiving tank recovery, separated water to warm water cleaning cycle homework.
技術(shù)優(yōu)勢對比
Comparison of technical advantages
人工清洗儲油罐作業(yè)人員從罐側(cè)壁檢修孔進(jìn)人儲罐內(nèi)搭梯進(jìn)行人工擦洗，儲罐空間狹小，空氣不流通，可燃性氣體濃度高，易發(fā)生中毒和爆炸事故，施工作業(yè)環(huán)境惡劣，嚴(yán)重地?fù)p害作業(yè)人員的身心健康;另一方面，從罐內(nèi)清除的污油及人工擦洗產(chǎn)生的大量污水造成罐區(qū)和周邊地區(qū)環(huán)境的污染，同時較長的清洗周期(平均為二個月)降低了庫區(qū)的儲存調(diào)節(jié)能力，直接影響庫區(qū)的正常生產(chǎn)，大量廢棄的罐底油還造成資源浪費和環(huán)境污染。對比傳統(tǒng)的儲罐清洗方式，機(jī)械清洗技術(shù)實現(xiàn)了儲罐全過程密閉清洗，具有清洗時間短、健康、安全、罐底油回收率高、社會效益及經(jīng)濟(jì)效益顯著的特點。
The storage tank operating personnel manual cleaning from the tank wall cleaning ladder manhole Jinren tank, tank space, air circulation, combustible gas concentration is high, prone to poisoning and explosion accidents, the construction work environment is bad, serious harm to the health of workers; on the other hand, a large number of sewage removal from the tank of oil pollution caused by the environment and cleaning the tank and the surrounding area pollution, at the same time cleaning cycle (mean two months) reduced the reservoir storage adjustment ability, directly affect the normal production of the reservoir area, a large number of waste oil tank bottom also caused the waste of resources and environmental pollution. Compared with traditional tank cleaning methods, mechanical cleaning technology achieves closed storage tank cleaning process, which has the characteristics of short cleaning time, health, safety, high recovery rate of tank bottom oil, remarkable social and economic benefits.
