Description

Technical Field

[0001] The utility model relates to the technical field of oilfield lubricant production equipment, and particularly relates to an oil-based lubricant production device based on the recovery of plant asphalt. Background Technique

[0002] In the field of oilfield drilling, lubricants are needed to ensure the stable and continuous progress of drilling work. The general method for the production and preparation of oil-based lubricants is to mix and heat multiple raw material solvents and then cool them. However, this method of producing lubricants has the problem of high cost due to the variety of raw materials. Data shows that plant asphalt is the waste residue in the process of vegetable oil processing, mainly burned as waste. Preliminary studies show that it contains about 10% sterols, 5% vitamin E and a large amount of higher fatty acids. Therefore, there is great beneficial space for its recycling and application in the preparation of oil-based lubricants. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic production equipment for the preparation of oil-based lubricants by recycling and utilizing plant asphalt in view of the deficiencies in the above background technique.

[0004] To achieve the above purpose, an oil-based lubricant production device based on the recovery of plant asphalt of the utility model adopts the following technical scheme:

[0005] An oil-based lubricant production device based on the recovery of plant asphalt includes a countercurrent reactor. The upper end of the countercurrent reactor is used for feeding crude plant asphalt, and the lower end is connected to a liquid-liquid separator. The upper end of the liquid-liquid separator is connected to a distillation column. The upper end of the distillation column is provided with an oleic acid outlet, and the lower end is connected to the liquid-liquid separator through a circulation pipe. The lower end of the liquid-liquid separator is connected to a reaction tank through a regeneration pump. The lower end of the reaction tank is connected to an asphalt oil pump. The asphalt oil pump is connected to a filter press, and the filter press is connected to a filtrate tank.

[0006] A further improvement of the oil-based lubricant production device based on the recovery of plant asphalt of the utility model is that the filtrate tank is connected to the reaction tank through a filtrate pump in a circulating manner.

[0007] A further improvement of the oil-based lubricant production device based on the recovery of plant asphalt of the utility model is that the reaction tank is connected to the countercurrent reactor through an absorption pump.

[0008] A further improvement of the oil-based lubricant production device based on the recovery of plant asphalt of the utility model is that the reaction tank is an acid and alkali resistant enamel steel structure reaction tank.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model integrates automatic feeding, production stirring, high-temperature reaction, discharging, and waste gas recovery of products, reduces the consumption of steel, reduces the labor load of on-site workers, and realizes automated operation.

[0011] 2. In the overall process of production and discharging of the product, the utility model reduces and avoids contact with the atmospheric environment. It can directly enter the production module unit from the raw material storage unit through an automated device, reducing the volatilization of chemically harmful gases into the atmosphere and polluting the environment.

[0012] 3. Most of the plant asphalt sold on the market is burned as waste, causing pollution to the atmospheric environment. After passing through this complete reaction system, a closed-loop production can be formed, and the plant asphalt can be refined to a higher requirement, realizing the effective utilization of waste. A special oil-based lubricant for situations such as sticking pressure during the drilling process is prepared, and by-product oleic acid is obtained, forming additional production increase benefits.

[0013] The fibrous impurities obtained after filtering by the filter press of the utility model can be used as a plugging material for drilling fluid after drying and losing water, realizing the full utilization of the crude plant asphalt and not generating additional waste.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Such as Figure 1As shown in the figure, an oil-based lubricant production device based on the recycling of plant asphalt includes an impact reactor 1. The upper end of the impact reactor is used for feeding the crude plant asphalt, and the lower end is connected to a liquid-liquid separator 2. The upper end of the liquid-liquid separator is connected to a distillation column 3. The upper end of the distillation column is provided with an oleic acid outlet, and the lower end is connected to the liquid-liquid separator through a circulation pipe. The lower end of the liquid-liquid separator is connected to a reaction tank 5 through a regeneration pump 4. The lower end of the reaction tank is connected to an asphalt oil pump 6. The asphalt oil pump is connected to a filter press 7, and the filter press is connected to a filtrate tank 8. The filtrate tank is connected to the reaction tank through a filtrate pump 9 in a cycle. The reaction tank is connected to the impact reactor through an absorption pump 10. Specifically, the reaction tank is an acid and alkali resistant enamel steel structure reaction tank.

[0018] The working principle of the present utility model is as follows: The crude plant asphalt flows through the impact separator. In the liquid-liquid separator, by changing the acid value, a small amount of vegetable oil and black plant wax paste are separated. In the distillation column, oleic acid by-products are separated through a high-temperature stripping process; the black plant wax paste separated by the liquid-liquid separator is pumped into the reaction tank through the regeneration pump, and reacts with maleic acid in the reaction tank to obtain acidified oil. Due to the high-temperature reaction at 200 °C in the reaction tank, the acidified oil easily forms hydrogen bonds with sulfur atoms in molybdenum disulfide through electrostatic charge interaction, adsorbs molybdenum disulfide, and obtains a black low-viscosity liquid oil mixture, which contains some fibrous impurities; after flowing through the filter press, the fibrous impurities are removed to obtain a relatively pure black low-viscosity liquid oil; after passing through the filtrate tank, high-purity black oil products are extracted and separated, which are the graft-modified oil-based lubricants for drilling fluids.
