Description
Technical field
The utility model relates to acyl chlorides technical fields, in particular to a kind of for producing the device of acyl chlorides.
Background technique
Acyl chlorides is a kind of carboxylic acid derivates, is a kind of important organic intermediate, is widely used in producing surfactant, make
The industries such as paper gluing agents, polymeric initiator.In traditional acyl chlorides production equipment, glassed steel reaction vessels, connecting tube are mostly used
Road generally uses stainless steel material or glass lined pipeline.Long-time service has the following problems:
1) for stainless steel material, due to there is acidic materials in acyl chlorides production, chloride ion can destroy metal oxide film protection
Layer forms spot corrosion or pitting corrosion, and perishable perforation, there are biggish security risks, need periodic inspection or replacement pipeline, increase
Production cost, while also influencing execute-in-place environment.
2) for enamel material, although corrosion-resistant, enamel material is in temperature change and under having Vibration Condition, very
It is easy burst porcelain, once burst porcelain, glassed steel reaction vessels and enamel pipeline can be by the acid material corrosion failures in acyl chlorides.Practice card
Bright, the equipment of enamel material service life in acyl chlorides production is short, easily leaks, there are very big security risks.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides one kind and is able to solve acyl chlorides production
In the process equipment and the problem of corrosive pipeline, reduce and leak, eliminate safe hidden trouble while guaranteeing that product quality is used to producing acyl
The device of chlorine.
To achieve the goals above, the device for producing acyl chlorides of the utility model has following constitute:
The device includes photochemical kettle and catches up with light kettle, and the photochemical kettle and catching up with is connected between light kettle by pipeline,
The pipeline, photochemical kettle and light kettle is caught up with to all have four fluorine structures of lining, four fluorine structure of lining successively includes being set to carbon steel
The stainless steel wire stratum reticulare of basal layer, the polytetrafluoroethylene ethylene layer for being set to the stainless steel wire stratum reticulare, in prefabricated reaction kettle
First pre- plant, welding wire, steel mesh heat F4 powder and carry out roller coating, make polytetrafluoroethylene (PTFE) and steel wire as reinforcing rib on mould inner wall
Net, which fuses into one, firmly to be adhered on the steel plate, then the treatment process such as heated.
The photochemical kettle and catch up with light kettle, can be used under conditions of positive/negative-pressure, high temperature, deep-etching, in 200 DEG C of temperature and
40 millipascal of vacuum does not play packet and does not inhale flat not dilatancy, reached the bodies such as steel fluorine hereinafter, shock heating quenching blocked operation." steel wire
Teflon lined " efficiently solves damage of two kinds of material expansion differences to lining, ensure that steel lining tetrafluoro equipment
Service life.
The photochemical kettle and light kettle is caught up with to be provided with stirring structure.
Using the utility model for producing the device of acyl chlorides, equipment and corrosive pipeline in acyl chlorides production process are solved
Problem reduces leakage, eliminates safe hidden trouble, while guaranteeing product quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the device for producing acyl chlorides of the utility model.
Appended drawing reference
1 photochemical kettle
2 catch up with light kettle
3 lining tetrafluoro pipelines
4 stirring structures
Specific embodiment
In order to more clearly describe the technology contents of the utility model, carry out combined with specific embodiments below into one
The description of step.
As shown in Figure 1, the device provided by the utility model for producing acyl chlorides includes photochemical kettle 1 and catches up with light kettle 2, it is described
Photochemical kettle 1 and catching up be connected between light kettle 2 by pipeline 3, the pipeline, photochemical kettle 1 and light kettle 2 is caught up with to all have lining tetrafluoro
Structure, four fluorine structure of lining successively include stainless steel wire stratum reticulare, polytetrafluoroethylene ethylene layer, wherein in four fluorine structure of lining
Stainless steel wire stratum reticulare adjacent to carbon steel substrates layer inner surface be arranged.
Lining tetrafluoro (F4) main component is polytetrafluoroethylene (PTFE), has the characteristics that antiacid alkali resistant, resists various organic solvents, almost
Insoluble in all solvents.Meanwhile the coefficient of friction for serving as a contrast F4 is extremely low, it can be to avoid the corrosion of equipment pipe, and can bear certain
Negative pressure.Therefore, in conjunction with the case where the process characteristic and temperature, pressure of acyl chlorides production, using molding lining F4 pipeline and " steel wire is poly-
Tetrafluoroethene lining " serves as a contrast tetrafluoro reactor.
In a kind of preferably embodiment, the photochemical kettle and light kettle is caught up with to be provided with stirring structure 4.
Using the utility model for producing the device of acyl chlorides, solve in acyl chlorides production process equipment and corrosive pipeline with
And product color the problem of deepening, strict control metal ion enter in acyl chlorides product, improve acyl chlorides product quality, reduce
Because of leakage of perforating caused by equipment corrosion, eliminate safe hidden trouble, it can economy and efficient delay apparatus service life and guarantor
Demonstrate,prove the stability of product.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still may be used
With the spirit and scope that various modification can be adapted and converts without departing from the utility model.Therefore, the description and the appended drawings should be considered
It is illustrative and be not restrictive.
