specific Embodiment approach 1

[0024] Specific implementation mode one: the compound fuel using oily sludge in this embodiment is made from oily sludge, auxiliary fuel, binder, curing agent and combustion improver, wherein the mass ratio of oily sludge to auxiliary fuel is (1~5 ): 1. The amount of binder or solidifying agent added is 0.5% to 3% of the mass of composite fuel using oily sludge, and the amount of combustion aid added is less than 1% of the mass of composite fuel using oily sludge; the application The calorific value of the composite fuel of oily sludge is 4000-5000kCal / kg;

[0025] The oily sludge is well site sludge, oil sludge in a joint station tank, drilling sludge or oily mud sand;

[0026] The auxiliary fuel is pulverized coal, weathered coal or coal gangue;

[0027] The binder is polyacrylamide;

[0028] The curing agent is calcium aluminate or sodium silicate;

[0029] The combustion aid is a coal combustion aid.

specific Embodiment approach 2

[0030] Embodiment 2: This embodiment differs from Embodiment 1 in that the mass ratio of the oily sludge to the auxiliary fuel is 1:1. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0031] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the mass ratio of the oily sludge to auxiliary fuel is 1.5. Others are the same as those in the first or second embodiment.

Abstract

The invention provides composite fuel using oil-containing sludge and a preparation method thereof, relates to composite fuel and a preparation method thereof and belongs to the field of composite fuel preparation. The composite fuel and the preparation method aim at solving the technical problem that existing oil-containing sludge contaminates the environment. The composite fuel using oil-containing sludge is prepared from the oil-containing sludge, auxiliary fuel, an adhesive, a curing agent and a combustion improver. The preparation method includes the steps that the oil-containing sludge, the auxiliary fuel, the adhesive, the curing agent and the combustion improver are mixed, stirred, dehydrated, smashed, set and dried, and the composite fuel is obtained. The composite fuel using the oil-containing sludge and the preparation method belong to resource utilization of the oil-containing sludge. The problem about use of the oil-containing sludge is solved. Meanwhile, the heat value in the oil-containing sludge is utilized, the aim that harmful components in the oil-containing sludge are harmless is achieved, waste is turned into wealth, and products with additional value are produced. Investment is little, the composite fuel takes effect quickly, cost performance of the product is high, operation is easy, and the composite fuel has large competition advantages.

Description

technical field [0001] The invention relates to a composite fuel and a preparation method thereof. Background technique [0002] Oilfield oily sludge refers to the mixture of mud, sand and water polluted by crude oil and other organic substances, which is produced in oilfield production activities and mainly comes from various links of crude oil gathering, transportation and processing. Among them, the particle size ≥ 74 μm is oil sand, and the particle size < 74 μm is oily sludge. Oily sludge sand and oily sludge are hazardous wastes listed in the National Catalog of Hazardous Wastes. The hydrocarbons contained in the oil mud sand produced in the process of oil production and storage and transportation in the oil field are harmful to the environment and need to be treated in a harmless manner. It is both a waste and a valuable secondary resource, and comprehensive utilization must be considered during treatment. At present, my country's energy production structure is s...
