Abstract
The utility model discloses a reation kettle for producing phosphorus flame retardant, including reation kettle body and polytetrafluoroethylene pump, be equipped with reactant entry and the 2nd reactant entry on the reation kettle body lateral wall, reation kettle body bottom is equipped with the export of the 2nd reactant, the polytetrafluoroethylene pump passes through the 2nd reactant entry and the export mixes circulation pipeline of pipe connection reation kettle body, the first raw materials source of reactant entry intercommunication, wherein, a reactant of reation kettle body enters the mouth and/or the 2nd reactant enters the mouth to the multiunit, follows reation kettle evenly distributed on every side between each group. The utility model discloses a reation kettle can make raw materials intensive mixing and the contact of participating in the synthetic technology of phosphorus flame retardant, improves reaction efficiency, and it is extravagant to reduce reaction material.
Description
Technical field
The utility model relates to a kind of chemical reaction equipment, particularly relates to the reactor for the production of phosphorus flame retardant.
Background technology
Phosphorus flame retardant is one of the most frequently used fire retardant kind in the fields such as building, mining industry, because its good flame retardant effect, cheap price are subject to the extensive welcome in market.The production process of phosphorus flame retardant is mostly similar, for common bisphenol-A to diphenylphosphate (BDP), the technological process of production is: solid feed bisphenol-A and catalyst are sent in reactor through cast feeder, liquid POCl3 is by pump, pipeline, being transplanted in reactor through mass flowmenter metering, carrying out an esterification through fully dissolving.Then in reactor, add liquid phenol (nitrogen protection), make the material in reactor carry out secondary esterification, generate thick BDP product.The thick BDP product of gained, through repeatedly washing extraction, after carrying out separated recovery toluene, obtains end-product BDP after dehydration.The technological process of production of other phosphorus flame retardants is then substantially similar therewith.
In the production process of phosphorus flame retardant, because the material viscosity in reactor is comparatively large, material is difficult to carry out full and uniform reaction, and reaction not exclusively causes reaction controlling difficulty to increase and production cost improves.
Summary of the invention
For the deficiencies in the prior art, the utility model discloses a kind of reactor for the production of phosphorus flame retardant, adequately achieve the abundant mixing between the two kinds of liquid materials synthesizing phosphorus flame retardant, achieve the abundant reaction of the two, improve production efficiency.
Above-mentioned alleged raw material, depends on the particular type of produced phosphorus flame retardant.For bisphenol-A to diphenylphosphate (BDP), two kinds of liquid materials refer to the liquid phenol that esterification phosphorus trichloride used, secondary esterification are used respectively; Other phosphorus flame retardant by that analogy.
Specifically, the utility model is achieved by the following technical solution:
For the production of a reactor for phosphorus flame retardant, comprise reactor body and polytetrafluoroethylene (PTFE) pump, reactor body sidewall is provided with the first reaction raw materials entrance and the second reaction raw materials entrance, and reactor body bottom portion is provided with the second reaction raw materials outlet; Polytetrafluoroethylene (PTFE) pump forms circulation line by the second reaction raw materials entrance and exit of pipeline coupled reaction still body; First reaction raw materials entrance is communicated with the first raw material source; Wherein, the first reaction raw materials entrance and/or the second reaction raw materials entrance of reactor body are many groups, are uniformly distributed between each group around reactor.
Above-mentioned the first alleged raw material, the second raw material refer to two kinds of liquid materials involved in phosphorus flame retardant production process.Improved by said structure, enter reactor body at esterification reaction process Raw due to a point different mouth, achieve raw material abundant mixing spatially and uniform contact, reduce material viscosity, improve reaction efficiency.
In said structure, store a kind of liquid material in the first raw material source, another kind of liquid material joins in reactor, circulates under the effect of polytetrafluoroethylene (PTFE) pump.
In order to realize better contacting between raw material, each first reaction raw materials entrance and/or the second reaction raw materials entrance are equipped with multiple manhole osculum.Under this structure, raw material, with spraying head type ejection blending contact, achieves storeroom contact area and maximizes.
In order to improve the contact between material further, control grume, in reactor body, suspention has agitating device.
Accompanying drawing explanation
Fig. 1 is reactor structural representation of the present utility model.
Detailed description of the invention
In order to structure of the present utility model and working method are better described, as follows in conjunction with the accompanying drawings.Be only schematic shown in structure as described below and accompanying drawing, not draw in proportion, also do not limit the features such as its size, shape, material, specification.Those skilled in the art still belong to protection domain of the present utility model in the improvement understood and grasp the present utility model essence basis is carried out.
As shown in Figure 1, reactor of the present utility model, comprises reactor body 1, and the sidewall of reactor body is respectively equipped with many groups the first reaction raw materials entrance 5 and the second reaction raw materials entrance 3, and each group enters around opening's edge reactor to be uniformly distributed.
Wherein, the second reaction raw materials entrance 3 and the second reaction raw materials of reactor body bottom portion export 4 and form circulation line by pipeline coupled reaction still body under the drivings of polytetrafluoroethylene (PTFE) pump 2, drive the second reaction raw materials to circulate in whole course of reaction; First reaction raw materials entrance 5 is communicated with the first raw material source 6, in the driving downhill reaction still body of raw material source, add the first reaction raw materials.
Wherein, each first reaction raw materials entrance and the second reaction raw materials entrance form gondola water faucet shape head by multiple manhole osculum.
Wherein, in reactor body, suspention has rabbling mechanism 7, and the flabellum of this rabbling mechanism gos deep into reactor body bottom portion, is used for the first and second raw materials to be uniformly mixed, and fully contacts.
Wherein, above-mentioned the first alleged reaction raw materials and the second reaction raw materials refer to the liquid reaction raw material participating in generating phosphorus flame retardant, a kind of reaction raw materials is stored by the first raw material source and joins in reactor body, and another reaction raw materials adds from the upper opening of reactor body and recycles under the drive of pump.
