Problems solved by technology

But this technology still has some defects, because its thermal cracking temperature may be as high as 590 degrees, and the pressure of the heating tube will be as high as 172kPa, so the requirements for equipment are high, the safety of the processing system is low, the investment cost is large, and the operating cost is high

Embodiment Construction

[0043] figure 1 , figure 2 and image 3 Show a kind of embodiment of the recovery processing method of waste industrial oil of the present invention, its concrete flow process is:

[0044]Use the pump 2 to pump the fresh waste oil in the fresh waste oil storage tank 1 through the inlet pipe 11 into the heat exchanger 10 for the first heat exchange. In the heat exchanger 10, the fresh waste oil absorbs the waste oil from the heated waste oil The heat of the mixture (how to obtain it will be described later) is preheated, usually to 110°C-150°C, at this time, the extremely volatile components in the fresh waste oil, that is, the volatile components with a boiling point lower than this temperature, evaporate Becoming steam (accounting for about 0.5% of total gas weight) enters cooler 90 through pipeline 12, then enters cooler 100, and the cooling medium of cooler 90 and cooler 100 is water. After continuous cooling, the refined oil is obtained. After the first heat exchange,...

Abstract

The invention discloses a recycling method and device of waste industrial oil. The method comprises the following steps: fresh waste oil performs heat exchange with the heated waste oil mixture and the vapor of the volatile component in turn for temperature rising, wherein in the temperature rising process, the volatile component in the fresh waste oil is evaporated into vapor; after passing through a pressure balance adjustment device, the fresh waste oil performs thermal cracking reaction at 360-420 DEG C under atmospheric pressure, wherein in the reaction process, the vapor of the volatilecomponent is buffered firstly and performs heat exchange with the fresh waste oil secondly; the vapor of the volatile component performs stepped cooling to obtain finished oil products, the finished oil products are collected respectively; the residual non-volatile oil in the waste oil mixture is discharged; and the discharged waste gas in the cooling process is collected to provide heat for the cracking reaction. The device of the invention comprises a heat exchanger, a pressure balance assembly, a reaction furnace, a buffer, a cooler and a waste gas collection system. The method of the invention has low investment cost and operation cost and high safety factor.

Description

technical field [0001] The invention relates to a method for recovering and treating waste industrial oil and equipment for implementing the method. Background technique [0002] With the rapid growth of our country's economy and the improvement of people's lives, the amount of industrial oil and automobile oil has increased rapidly, and the amount of waste oil has also increased rapidly. These waste oils need to be processed and utilized by scientific and technological means. However, the treatment methods for these waste oils in the existing technology are still in a relatively backward state, and the speed and degree of technological development are far behind the actual needs, let alone the efficient recycling of resources to meet the development of low-carbon in my country The needs of economy and green economy. At present, the shortage of resources hinders the economic development of our country. Therefore, it has become an important topic to use the renewable value of...
