Embodiment 1

[0027] Embodiment 1: as attached Figures 1 to 5As shown, the waste oil sludge harmless recycling device includes a waste oil dehydration sedimentation tank 1, a waste oil purification tank 2, a sewage purification treatment equipment 3 and a sludge treatment equipment 4, and a waste oil dehydration sedimentation tank 1 is provided with a sewage Sludge inlet, at the lower end of the sludge dehydration sedimentation tank 1, there are respectively a sludge oil outlet, a first dehydration outlet connected to the sewage inlet of the sewage purification treatment equipment 3 through pipelines, and a sludge inlet of the sludge treatment equipment 4 The first sludge outlet connected through the pipeline is respectively provided with a demulsifier dosing port, a flocculant dosing port, and a dirty oil inlet connected with the dirty oil outlet through a pipeline on the upper part of the dirty oil purification tank 2. The lower end of the purification tank 2 is provided with a purified ...

Embodiment 2

[0042] Embodiment 2: as attached figure 1 As shown, the using method of the sludge harmless recycling device described in embodiment 1 is carried out as follows: the oily sewage produced in the production process of the refinery 25 and the oil storage process of the oil storage tank area 26 and The waste oil derived from the oil field 24 is used as sludge; the first step is to send the sludge into the sludge dehydration sedimentation tank 1, and then add a mass percentage of 1.3% to 1.5% demulsifier solution, add 40 kg to 45 kg of demulsifier per ton of sludge, after the sludge is evenly mixed with the added demulsifier under the stirring of the fast mixer 5, the sludge is demulsified and separated for the first time, The stirring time is 1 hour to 2 hours. After the stirring is completed, the mixed dirty oil separated in the upper part of the sewage oil dehydration sedimentation tank 1 is transported to the sewage oil purification tank 2, and the demulsification separation in...

Embodiment 3

[0050] Example 3: As an optimization of Example 2, in the first step, the 1.3% to 1.5% demulsifier solution is formed by dissolving the demulsifier in desalted water.

Abstract

The invention relates to the technical field of sludge treatment and discloses a harmless oil sludge recycling device and a using method thereof. The harmless oil sludge recycling device comprises a sump oil dewatering and settling tank, a sump oil purification pool, sewage purification equipment and sludge treatment equipment. According to the harmless oil sludge recycling device and the using method thereof, disclosed by the invention, the dewatering effect and oil removing effect of the oil sludge can be improved, the purified water and purified oil can be obtained after oil sludge treatment, the purified water can serve as cooling water in oil refinery for reuse, and the purified oil is settled and dewatered to serve as a raw material of the production device for reuse. The harmless oil sludge recycling device and the using method thereof, disclosed by the invention, have the advantages that water and oil can be fully recycled, waste of resources is avoided, the sludge obtained by treating the oil sludge by using the harmless oil sludge recycling device disclosed by the invention is finally combusted, contaminants produced in the sludge combustion process are reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, and relates to a harmless recycling and reuse device for sludge and a method for using the sludge. Background technique [0002] With the development of oilfields, a large amount of waste oil is produced in the oilfield area, which contains a large amount of water, sediment and other impurities. At the same time, the production equipment (refining equipment, etc.) A certain amount of oily sewage, waste oil, and oily sludge is produced. If the oily sewage, waste oil, and oily sludge are discharged directly, it will cause serious pollution to the environment, which is not in line with the concept of coordinated development of the environment and economy. In order to recycle and reuse this part of oil resources and water resources in waste oil, oily sewage and oily sludge, the waste oil sludge (waste oil, oily sewage and oily sludge) is treated to recover oil resources and water resources ...
