Description
Technical Field
The utility model relates to an oil field hazardous waste handles technical field, concretely relates to fatlute pretreatment systems.
Background
Oil sludge produced in oil extraction and refining industry in China is millions of tons every year, and is rapidly increased every year, and oil-containing sludge is classified as H08 dangerous waste in national hazardous waste record (No. 39 of the 2016 environmental protection department), because the oil sludge contains various teratogenic and carcinogenic toxic substances, such as benzene series, phenol, anthrax, and anthracene. The reduction, harmless and resource treatment of the oily sludge is urgent, and in this respect, the domestic technical research is less, and the cases of the successful introduction of foreign technologies are less.
The oily sludge has various types and complex properties, and corresponding treatment technologies and equipment also show diversified trends. The main processes for treating oil sludge adopted in domestic oil fields at present are pyrolysis, incineration and hot washing for treating oil-containing sludge. Each mainstream process method for treating oil sludge relates to pretreatment of oil sludge. The existing pretreatment method mainly comprises the following steps: (1) hot water leaching and fluidizing in the tank. The disadvantages of this approach are: in the residual pool of large oil sludge, sundries and settled sand, the oil sludge needs to be transported outside for additional treatment, and in addition, the crude oil is not washed out thoroughly, so that the environment of a working place is dirty and messy. (2) The main reactor and the sand setting air flotation. Specifically, the impurities of the feeding slurry in the oil sludge tank are removed by using a grid, and then the feeding slurry enters a main reactor and a sand setting air flotation module, and oil and sludge are separated under the action of heating, stirring and chemical agents. The disadvantages of this approach are: for impurities which have larger volume or are easy to block a filtering system, such as large bricks, woven bags and the like, a manual method is adopted for screening and outward transportation treatment. Moreover, the treatment scale is smaller, and the environment of a working place is dirtier. (3) Mincing, grating and fluidizing pretreatment. Specifically, oily sludge is crushed by a reamer crushing system and sorted by a grid, impurities and large materials separated by the grid are washed by hot water and then are transported out for treatment, and screen underflow of the grid enters a sludge fluidization pretreatment device. The disadvantages of this approach are: the treatment scale is small, and the environment of a working place is poor.
