The distilling apparatus comprises a distiller, a distillation separator and a measuring tank which are sequentially connected by pipelines; the vacuum system is a vacuum pump; and the nitrogen device comprises an air compressor and a nitrogen making machine which are sequentially connected by a pipeline. According to the utility model, by adding the nitrogen device, the distilling process is improved, byproducts are removed and materials in a system can be protected from being oxidized; and yield is further improved and product quality and the production environment are improved.
Description
Technical field
The utility model relates to a kind of dewatering unit, specifically refers to a kind of dewatering unit for the production of the lubricant product.
Background technology
The lubricant product uses unsaturated fatty acids and organic amine as main raw material(s), the normal by product that generates in reaction: water, water is easy to form emulsified water with the sufficient starting material of unreacted or work in-process, how the water in the cleaning reaction just becomes the successful key of reaction, because water will directly affect the quality of reaction efficiency and the finished product.
The simplest method is exactly according to reaction mass, system is directly distilled, but because product system is as main raw material(s) with unsaturated fatty acids and organic amine, temperature of reaction is very high, so the emulsified water that forms is very firm, be difficult to breakdown of emulsion distillation, it is in addition very high to distill required energy consumption, so be not suitable for adopting this method.
At present traditional method is arranged also: the xylene solvent method of carrying is removed by product.Its principle of work: dimethylbenzene is dropped in the reactor that has reacted to a certain degree, and material extremely seethes with excitement in the temperature reaction still, the water that generates in the reaction is constantly distilled by solvent take out of, collects and enters withdrawing can; Difference according to material proportion is separated distillment.Because dimethylbenzene proportion is lower than water, dimethylbenzene is on the upper strata, distillment in the withdrawing can is carried out settlement separate, remove the water of lower floor after, reclaim dimethylbenzene and again add the reactor internal recycle and use, until moisture is distilled totally.With the carrying out of reaction, temperature in the kettle will improve gradually, and will be not oxidized in order to protect product, and the color of product is unlikely to become more dark, and we will carry out vacuum in the still, and the boiling point that reduces system temperature by negative pressure carries out whole still-process.
Traditional method is in whole still-process, although can reduce the boiling point of system by negative pressure, can remove most by product (being mainly water), but the boiling point of the boiling point of solvent xylene and product is very approaching, the boiling point of slightly low product only, so be difficult to be completely removed, the part resistates is always arranged in product, cause having all the time in the product taste of solvent xylene; Owing to utilize the negative pressure of vacuum distillation, cause part dimethylbenzene to be entered atmosphere by volatilization in addition, directly contaminate environment.Well-known benzene class gang material belongs to carcinogens, and the concentration that allows in the air is very low, so Long Term Contact is to human body and environment and harmful.
The utility model content
The purpose of this utility model is to provide a kind of can effectively remove water byproduct, does not produce harmful material, can also improve the dewatering unit for the production of the lubricant product of production capacity.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of dewatering unit for the production of the lubricant product comprises the water distilling apparatus, vacuum system and the nitrogen device that are connected with reactor;
Described water distilling apparatus comprises successively distiller, fractionation by distillation device and the test tank that connects by pipeline, and the pipeline at the top of described distiller by placing described reactor is communicated with described reactor;
Described vacuum system is a vacuum pump, and is connected with the top of described reactor by pipeline;
Described nitrogen device comprises air compressor and the Nitrogen plant that connects by pipeline successively, and described Nitrogen plant is communicated with described reactor by the nitrogen tube that places reactor.
Further, be equipped with valve on the described pipeline.
Further, the pipeline that described vacuum pump is corresponding is provided with tensimeter.
The utility model can improve many deficiencies of solvent method effectively, we improve distillation process by adding the nitrogen device, remove by product, during actual production, in design temperature downhill reaction still, pass into nitrogen, remain certain nitrogen gas concn in the still, adopt the ladder-elevating temperature method, improve constantly the distillation temperature of system, nitrogen constantly will react the water that generates gradually by circulation to be taken away, and nitrogen can protect the material in the system not oxidized; When system temperature reaches the design temperature limit, close nitrogen, system is carried out last distillation dehydration by negative pressure of vacuum, until anhydrous go out till, the utility model improves distillation process by the adding of nitrogen device, and production capacity further improves, and quality product and production environment improve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Now by reference to the accompanying drawings, describe the utility model in detail.
With reference to accompanying drawing 1, a kind of dewatering unit for the production of the lubricant product comprises the nitrogen device 2, water distilling apparatus 3 and the vacuum system 4 that are connected with reactor 1;
Vacuum system 4 is a vacuum pump 41, and is connected by the top of pipeline with reactor 1; Correspondence is provided with tensimeter 42 on this pipeline;
The nitrogen that nitrogen device 2 produces constantly will react gradually the water that generates by circulation and take away; When system temperature reaches the design temperature limit, close nitrogen, the negative pressure that system is produced by vacuum system 4, and carry out last distillation dehydration in conjunction with water distilling apparatus 3, until anhydrous go out till.
In addition, be equipped with valve on every pipeline.
Above-described the utility model embodiment does not consist of the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
