Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 Shown: the technical solution includes an oil filter funnel 1, a waste engine oil storage tank 2, two pipeline filters 3 and 4, two screw metering pumps 5 and 6, and attached flow, pressure, temperature instruments, etc., coal The slurry tank 7, the high-pressure coal slurry pump 8, and the gasifier 9 are all existing devices. Among them, the oil filter funnel 1 can be made by oneself, with a cover, and a first-level filter screen is arranged inside, and the filter screen specification is 40 mesh; the waste engine oil storage tank 2 is made of ordinary carbon steel, and the specification is Effective volume 6m 3 ;Pipeline filtration 3 and 4 use ordinary pipeline oil filters, also known as oil suction filters. The screw metering oil pump with low head and small flow rate can meet the process requirements, and it is ready for one ope...

Abstract

The invention discloses a device and use method for treating waste engine oil by using blending combustion through a coal gasification furnace. The device comprises an oil filtering funnel, wherein awaste engine oil storage tank is arranged right below the oil filtering funnel; two pipelines are connected with a liquid outlet of the waste engine oil storage tank in parallel; one pipeline is provided with a first filter and a first screw metering pump, and the other pipeline is provided with a second filter and a second screw metering pump; waste engine oil subjected to two-stage filtering isconnected to an inlet pipeline of a high-pressure coal slurry pump; and then the waste engine oil is conveyed into the gasification furnace through the high-pressure coal slurry pump. The collected waste engine oil is filtered through the oil filtering funnel, and then is added into the middle waste engine oil storage tank for storage; after being further filtered through the pipeline filters andmetered by the screw metering pumps, the waste engine oil is sent to the inlet pipeline of the high-pressure coal slurry pump in a small flow; and the waste engine oil is mixed with a large amount ofcoal slurry, and then is sent into the gasification furnace to be incinerated through the high-pressure coal slurry pump. The device and use method for treating the waste engine oil by using blendingcombustion through the coal gasification furnace has the characteristics of saving coal resources and turning waste into wealth.

Description

technical field [0001] The invention relates to the technical field of coal gasification furnaces, in particular to a device and method for co-firing waste engine oil with coal gasification furnaces. Background technique [0002] The so-called waste engine oil refers to the fact that the engine oil is mixed with other impurities during use, such as water, dust, other miscellaneous oils and metal powder produced by the wear and tear of machine parts, etc., causing the color to turn black and the viscosity to increase. Its main components are base oil, Additives, water, impurities, etc.; the second refers to the gradual deterioration of the oil, producing organic acids, colloids, and asphalt-like substances, and its main components become organic acids, colloids, and asphalt-like substances. Waste engine oil regeneration technology is relatively mature, and methods such as sedimentation, distillation, pickling, alkali washing, and filtration are often used to remove impurities...
