Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a tetrabromobisphenol A bromination reactor. Background Art

[0002] Tetrabromobisphenol A is a highly effective flame retardant, mainly used to improve the flame retardancy and self-extinguishing properties of materials. It can be used as a reactive flame retardant in epoxy resins and polyurethane resins to improve the flame retardancy of materials through chemical reactions. In addition, it can also be used as an additive flame retardant in polystyrene, SAN resin and ABS resin, etc., to provide a highly effective flame retardant effect.

[0003] During the bromination reaction of tetrabromobisphenol A, after the reaction liquid undergoes low-temperature bromination reaction, the reaction liquid needs to be heated to 70-80°C for enhanced bromination reaction. In order to heat the reaction liquid in the reactor, a heating pipe is installed on the outside of the reactor to directly heat the reaction liquid in the reactor to a specified temperature range. At the same time, in order to prevent the temperature loss of the heating pipe, an insulation layer is installed on the outside of the reactor. However, after the enhanced bromination reaction of the reaction liquid is completed, it is necessary to wait for the reaction liquid to cool to 10-30°C before vacuum filtration can be performed. However, since an insulation layer is installed on the outside of the reactor, it takes a long time for the reaction liquid in the reactor to cool naturally, which will seriously affect the bromination reaction rate of tetrabromobisphenol A.

[0032] Working principle: when the reaction liquid in the reactor body 1 needs to be heated, the personnel pours a certain amount of clean water into the outer jacket tank 5 through the water inlet pipe 8, and then controls the operation of the heating tube 6, so that the heating tube 6 heats the water in the outer jacket tank 5, which is beneficial to the water-insulated heating of the reactor body 1 and the uniform heating of the reaction liquid in the reactor body 1. When the reaction liquid in the reactor body 1 needs to be cooled, the personnel controls the solenoid valve 10 to open, so that the hot water in the outer jacket tank 5 is discharged through the drain pipe 9, and then introduces cold water into the outer jacket tank 5 through the water inlet pipe 8, and the cold water in the outer jacket tank 5 flows through the drain pipe 9. The cold water exchanges heat with the reactor body 1, which is beneficial to the rapid cooling of the reaction liquid in the auxiliary reactor body 1, thereby effectively improving the bromination reaction efficiency of tetrabromobisphenol A.

[0033] When the reactor body 1 is subjected to water insulation heating or cold water flows in the outer jacket tank 5, the motor 25 drives the annular plate 15 to rotate through the gear 26 and the gear ring 24. In the process of the mounting frame 16 rotating with the annular plate 15, the mounting frame 16 can drive the two first scraper strips 17 to respectively adhere to the outer wall of the reactor body 1 and the inner wall of the outer jacket tank 5 to rotate, and the mounting frame 16 can also resist the arc plate 20 during the rotation process, driving the arc plate 20 and the bent plate 19 to rotate synchronously, so that the second scraper strip 21 and the third scraper strip 22 respectively adhere to the bottom of the reactor body 1 and the outer jacket tank 5 to rotate, which can effectively prevent minerals such as calcium and magnesium in the water from crystallizing and depositing on the outer wall of the reactor body 1 and the inner wall of the outer jacket tank 5 to form scale, thereby preventing the scale from affecting the heat exchange efficiency of the reactor body 1.

[0034] When the reactor body 1 is heated in water insulation, tetrabromobisphenol A will generate steam during the bromination reaction. Harmful gases such as hydrogen bromide will be generated in the steam, so activated carbon is usually used to adsorb the harmful gases. In the process of heating the reaction liquid, the steam is discharged through the bent conduit 2, and the cold water in the cooling water tank 3 will exchange heat with the steam in the bent conduit 2, so that the moisture in the steam will condense when it is cold, and the condensed water droplets will flow into the guide box 27 through the bent conduit 2. The condensed steam will be filtered through the fiber filter plate 29, which can effectively remove the moisture in the gas, thereby effectively preventing the water molecules in the steam from inhibiting the adsorption capacity of the activated carbon.

[0035] When the annular plate 15 drives multiple driving blocks 34 to rotate, the driving block 34 will drive the bending push rod 35 to move upward through the arc edge. At the moment when the bending push rod 35 disengages from the driving block 34 through the vertical portion, the bending push rod 35 will move downward and reset under the drive of the compression force of the second spring 39. In this reciprocating manner, the bending push rod 35 can move back and forth up and down. During the reciprocating movement of the bending push rod 35 up and down, the hemispherical portion of the bending push rod 35 slides in contact with the connecting plate 32 through multiple baffles 33, and the drive of the compression force of the first spring 31 can cause the fiber filter plate 29 to vibrate continuously, which is beneficial to assisting the fiber filter plate 29 to shake off moisture and prevent water droplets from adhering to the outside of the fiber filter plate 29 and affecting the gas flow rate.
