Abstract
The utility model discloses a circulatory production device for trichloro propyl phosphate (TCPP). The circulatory production device comprises a reaction kettle, a closing valve and a closed reaction space formed by the closing valve, wherein particularly, a backflow device is arranged outside the reaction space and comprises a transport pipe and a pump, and the transport pipe is connected with the bottom of the reaction kettle, and is communicated with the reaction space by penetrating through the closing valve. According to the circulatory production device for TCPP, the backflow device is arranged outside the reaction space, a reaction raw material in the reaction kettle can enter the backflow device for circular reaction, and the reaction speed is accelerated, so that the reaction period is shortened, and the productivity of producing TCPP is improved.
Description
Technical field
The utility model relates to the circulation production device for tricresyl phosphate chloropropyl ester (hereinafter to be referred as TCPP), relates in particular to, and is mainly used in to belong to technical field.
Background technology
Fire retardant has wide market outlook in the every field such as chemical building material, electronic apparatus, communications and transportation, space flight and aviation, household furniture, upholstery, clothing, food, lodging and transportion--basic necessities of life.Under the situation of seeking environmental protection, safe fire retardant, phosphorus flame retardant without halogenated flame retardant, has overcome the shortcoming of halogenated flame retardant as a kind of effectively, has caused people's common concern.Tricresyl phosphate chloropropyl ester (TCPP) production equipment all is single reactors in the prior art, and reaction raw materials is natural reaction in reactor, and speed of response is slower, has affected the output of TCPP, so that production capacity is lower.
Summary of the invention
The purpose of this utility model is to solve above-mentioned technical problem, proposes the circulation production device of TCPP.
The purpose of this utility model, to be achieved by the following technical programs: the circulation production device of TCPP, comprise reactor, closing valve and the closed reaction compartment that forms thereof, it is characterized in that: described reaction compartment is provided with reflux outward, described reflux comprises delivery tube and pump, condenser, described delivery tube ligation still bottom, and penetrates closing cap and be connected with reaction compartment.
The beneficial effects of the utility model are mainly reflected in: the circulation production device of using the utility model TCPP, reaction compartment is provided with reflux outward, reaction raw materials in the reactor can enter the reflux circulating reaction, accelerated speed of response, so that shorten reaction time, improved the production capacity of producing TCPP.
Description of drawings
Fig. 1 is the structural representation of the circulation production device of the utility model TCPP.
Embodiment
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
The utility model is when implementing, the preferred version that has comprises: as shown in Figure 1, the circulation production device of TCPP, comprise reactor 1, closing valve 2 and the closed reaction compartment 3 that forms thereof, especially, reaction compartment is provided with reflux 4 outward, and reflux comprises delivery tube 41 and pump 42, this delivery tube ligation still bottom, and penetrate closing cap and be connected with reaction compartment.In addition, described transfer lime is provided with condenser 5.
During implementation, raw material is exported along delivery tube by the effect of pump in the reactor, enter closing valve and be back to reactor so that raw material can be in reaction compartment and reflux continuous periodic cycle, obtained abundant reaction.Transfer lime is provided with condenser, and raw material can produce a large amount of heat energy when reaction, and when raw material process transfer lime, condenser can reduce the temperature of raw material, guarantees the interior safety temperature that keeps of circulation production device of TCPP.
Can find out by above-mentioned character express, after the circulation production device of the utility model TCPP drops into and implements, its beneficial effect is mainly reflected in: the circulation production device of using the utility model TCPP, reaction compartment is provided with reflux outward, reaction raw materials in the reactor can enter the reflux circulating reaction, accelerate speed of response, so that shorten reaction time, improved the production capacity of producing TCPP.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
