Detailed Product Description
With the rapid development of oil refining industry by waste plastics, scrap rubber and waste engine oil, the fuel oil produced has been widely applied,and penetrated in all the fields of national economy and peoples daily lives. However, the rapid development and the increase of employees in the industry also enable the price of raw material to increase drastically. How to raise the added value of fuel oil on the basis of decreasing the cost of raw materialThe simplest method is to re-distill (or called rectify) the waste engine oil and raw oil extracted waste plastics and scrap rubber. The rectified oil is usually faint yellow or faint red liquid with main technical indexes reach the standards for 0# or -10# diesel, and may replace the 10# diesel in application. Its price is 1500Yuan/ton higher than that of raw oil. There are two options of the unit to regenerate the fuel oil: one is large petrochemical refining plant with investment more than 1 billion Yuan; the other is currently popular earth burner with investment between 50,000-100,000 Yuan. However, the earth burner has a bad performance in terms of operating efficiency, security and environmental protection. Thus, it is now an important subject to have less investment and overcome the weakness of an earth burner.
The traditional refinery equipment named earth burner in China now adopts horizontal fixed treater. The technological process is as below: first manually feed the waste engine oil and raw oil extracted from waste plastics and scrap rubber from the top of split treater, then seal up the feed inlet and heat up slowly the bottom of treater with coal of fuel; the volume of a split treater usually is 20 stere, plus15 tons of material, and usually the smelting completes in two weeks. After the smelting is over, stop for 12 hours to make the treater fully cool down, then open the dregs outlet at the bottom of treater to discharge dregs, feed material from the feed inlet of treater to continue another cycle of refining.
The three wastes treatment with domestic horizontal fixed treater fails to meet the requirements of environmental protection; and the quality of oil produced with air distillation method is poor, moreover, the output capacity is low.
By fostering the strengths and circumventing the weakness of large petrochemical refining plant and combining researches of other companies, Shangqiu Donghe has launched atmospheric and vacuum distillation unit with Donghe characteristics over years of scientific research based on Chinas practical conditions
