Waste oil regeneration system

Abstract

The invention relates to a regeneration system which can be used for treating waste oil into qualified absolute oil. The regeneration system comprises a reactor and a pressure filter, wherein a common inlet for a flocculating agent and waste oil, and an adsorbent powder feeding port are arranged at the upper end of the reactor; the regeneration system is further provided with a flocculating settling tank, a primary adsorption settling tank and a secondary adsorption settling tank, which are connected with the reactor; valves are respectively arranged in treatment pipelines; a mortar pump is arranged at the bottom of the reactor and can be used for pumping out substances in the reactor and respectively transporting the substances into the setting tanks through different treatment pipelines; a vacuum pump is arranged at the upper part of the reactor and can be used for transporting the substances in the upper parts of the settling tanks into the reactor through different treatment pipelines; the press filter is connected with the upper part of the secondary adsorption settling tank through an output pipeline; and a valve is arranged in the output pipeline. According to the waste oilregeneration system disclosed by the invention, the blockage of a pore of an adsorbent caused by flocculated sewage is mainly reduced and the adsorption effect is enhanced; and meanwhile, the blockage of a filter plate of the press filter caused by the flocculated sewage is also reduced.

Description

technical field [0001] The invention relates to the equipment field of waste oil regeneration technology for industrial oil, in particular to a regeneration system capable of processing waste oil into qualified clean oil. [0002] Background technique [0003] With the rapid development of the national economy, my country's machinery industry has also made great progress, leading to an increase in waste oil emissions. The SO2 and CO2 produced by incineration of waste oil as hazardous waste will pollute the environment, and the treatment of waste oil has become an urgent problem to be solved. Therefore, the State Environmental Protection Administration has listed waste oil as one of the three key points of the main control in the field of environmental protection in the 21st century. Engine oil is a high value-added product extracted from petroleum. With the shortage of oil resources, there are also problems in the supply and demand of engine oil. Waste engine oil regenerat...

Problems solved by technology

[0005] After searching, there are relatively advanced waste engine oil regeneration devices at present, such as the Chinese patent, published on October 31, 2008, with the announcement number CN201300008 "waste oil regeneration oil filter system" patent, which discloses a waste oil regeneration system. Oil regeneration system, which includes a reactor, a filter press, and a heat transfer oil heating circulation device, wherein the waste oil is coarsely filtered by the oil inlet control valve and then directly enters the reactor, and the flocculant and adsorbent are respectively added to the reactor. The waste oil is flocculated and adsorbed, but because the waste oil will form certain dirt after adding the flocculant, the flocculated dirt will quickly block and fill the pores of the adsorbent, thus affecting the adsorption effect; at the same time, due to the pressure The filter is connected to the oil outlet pipe at the bottom of the reactor, and the flocculated dirt will all accumulate on the filter plate of the filter press, and it is easy to cause blockage of the filter plate of the filter press. Therefore, the filter plate needs to be replaced frequently during use. It wastes time and increases trouble; in addition, in the above-mentioned technical scheme, the control of the amount of waste oil, flocculant and adsorbent does not adopt an automatic control feeding system, and the amount of feeding is mainly controlled by humans, and it cannot be done according to Precise filling according to the requirements of the formula; moreover, in the above technical scheme, since the vacuum separator is only installed after the press filter, the waste oil has not been vacuum dehydrated before the flocculation reaction and adsorption reaction, and the water has no effect on the flocculant, The flocculation and adsorption effect of the adsorbent has a great influence, so in the above technical scheme, the effect of treating waste oil with high water content is poor
