Embodiment 1

[0025] A microwave rapid processing method for petroleum sludge, comprising the following steps:

[0026] (1) Put the black and high-viscosity petroleum sludge into the pulverizer first, and crush the large petroleum sludge into materials with a diameter of 1cm, so that the materials can be heated more evenly;

[0027] (2) Transport the crushed material to the distributor on the microwave equipment for mechanical distribution, and spread the material evenly on the transmission belt of the microwave equipment. The thickness of the material is 1cm and the width is 85cm;

[0028] (3) Transfer the material after being distributed by the distributor to the microwave equipment cavity for continuous heating. The power density in the microwave cavity is 12KW / m 2 , the continuous heating time is 12 minutes, divided into three stages: the first stage microwave power is 3kw, the heating time is 5min, the temperature is 300℃~340℃; the second stage microwave power is 2kw, the drying time i...

Embodiment 2

[0031] A microwave rapid processing method for petroleum sludge, comprising the following steps:

Abstract

The invention discloses a rapid microwave treatment method of oil sludge. The method comprises the following steps that firstly, the oil sludge which is black and high in viscosity is put into a grinder to be smashed into small pieces of materials which are 1-2cm in size, then the smashed materials are transported to a material arrangement device on microwave equipment to carry out mechanical material arrangement, the materials are conveyed into a cavity of the microwave equipment, three-stage continuous heating is carried out, a gas washing device and a dedusting device are further provided in the heating process to recycle discharged gas, and after the three-stage heating is finished and the materials are cooled, treated oil sludge is obtained, wherein the obtained oil sludge is brick red in color and the weight loss rate is 58%-63%. Compared with traditional treatment methods, the method has the advantages that the time is short and 13-15 minutes are simply needed; the treatment temperature is relatively low, and waste gas can be treated clean at the temperature of 500 DEG C or below; microwave heating has a sterilization effect, and the treated oil sludge can not cause secondary pollution to environment; the operation is convenient, and continuous treatment can be carried out.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a high-efficiency and energy-saving microwave rapid processing method for petroleum sludge. Background technique [0002] Petroleum plays a pivotal role in modern industry and economic development. It is called "black gold" and "economic blood". It is widely used in transportation, petrochemical and other aspects. However, in the process of oil extraction, due to the influence of natural or human factors such as well washing, wellhead scattering, accident discharge, and oil tank cleaning, a large amount of crude oil leaks and mixes with gravel, sediment, weeds, etc., forming oily sludge. Among them, the sludge particles are unstable in nature, easy to cause air pollution and produce stench, which is a kind of extremely harmful solid waste, which has an impact on society and people's lives. [0003] The composition of petroleum sludge is complex, usual...
