該設(shè)備可提供最高 10——3000Hz 的頻率,實現(xiàn)了輸出電壓、電流的連續(xù)可調(diào),以達到輸出功率連續(xù)可調(diào)的目 的,由于中頻電源渦流感應(yīng)加強,導致集膚效應(yīng)更強,漏磁減少,因此電加熱效果大大好于工頻電源,節(jié)能效果達到 20%以上,大大地降低了采油生產(chǎn)能源的消耗該裝置是將空心抽油桿內(nèi)穿過電纜并與抽油桿桿體形成回路,通以工頻交流電,利用內(nèi)集膚效應(yīng)原理在空心抽油桿壁上產(chǎn)生熱能,對油管內(nèi)原油進行全程加熱,提高油管內(nèi)原油溫度,降低原油粘度,改善其流動性,防止油管內(nèi)原油結(jié)蠟,從而有效地開采高凝、高粘、高含蠟原油。

當鋼管中穿過電纜形成回路并通過交流電流時,鋼管截面中電流主要集中在鋼管內(nèi)表面,此現(xiàn)象稱為內(nèi)集膚效應(yīng),而鋼管的外 表面幾乎沒有電流通過,空心桿外壁可視為絕緣體,這種現(xiàn)象不僅隨著頻率的增高而明顯加強,而且還隨著導體半徑、磁導率和電導率的增高而表現(xiàn)的更加顯著。電加熱抽油桿就是利用內(nèi)集膚效應(yīng)工作的,由于空心抽油桿的交流阻抗遠大于導線的電阻,空心抽油桿為主要發(fā)熱體。中頻加熱電源主電路為 AC-DC-AC 變頻結(jié)構(gòu),由整流電路、濾波、逆變電路和保護電路組成。其工作原理是將三相50Hz 工頻交流電經(jīng)過三相全控整流橋整流成電壓可調(diào)的脈動直流,再通過電容將脈動 的直流電濾波變成光滑平穩(wěn)的直流電送到單相逆變橋,最后通過逆變橋?qū)⒅绷麟娮兂蓡蜗囝l率可調(diào)的中頻交流電供給負載。采用中頻電壓作為 取樣信號,無中頻電流互感器,輸出部分和負載的 連接不需區(qū)分極性。
人機對話的顯示界面,可通過鍵盤的選擇顯示工作頻率及電流,輸出脈沖的占空比、電流變比等, 并可顯示故障狀態(tài)及原因,使顯示更直觀,更易于操作。
輸出電壓、電流連續(xù)可調(diào),可以使加熱系統(tǒng)處于最佳工作狀態(tài),能源利用 率高,節(jié)能效果明顯恒輸出電壓/恒輸出功率控制選擇功能。The pulverized coal in groups is sent to the mixer room through the belt conveyor. In order to protect the environment, the tar residue transported from the gas purification facilities needs to be distributed back to the fired coal. The function of the mixer is to fully mix the pulverized coal and the added tar residue, recycle the waste residue, make the particle size distribution of the fired coal more uniform, and improve the quality of coke.The mixer adopts double screw mixing device to fully mix the materials. There are two mixers in total, with a single production capacity of 600t/h, one for production and one for standby. The blended coal is sent to the top of the coal tower. The coal sample preparation room is an integral part of the laboratory of the whole plant, which is composed of sample crushing and division room, sample storage room, sample drying room, etc. Its task is to collect and prepare samples, determine the moisture and particle size composition of each single coal and mixed coal, shrink and crush the coal samples to less than 1.5mm and 0.2mm, send them to the Central Laboratory of the plant for colloidal layer determination and industrial analysis,
