Wherein preferred technical scheme is, described heater comprises the heating tube be fixed in described crystallization kettle and the fin be fixed on described heating tube.
Preferred technical scheme is that described fin is arcuation further, and described fin is fixed on described heating tube between two relatively in groups.
Preferred technical scheme also has, and described crystallization kettle is also provided with evacuation port and liquid level display.
Preferred technical scheme also has, and the bottom in described crystallization kettle is provided with sieve plate, and described discharge nozzle is arranged on the below of described sieve plate; Described heater is arranged on the top of described sieve plate.
Preferred technical scheme also has, and the bottom of described crystallization kettle is also provided with delivery line.
Advantage of the present utility model is with beneficial effect: described crystallisation phenol separation equipment is specially adapted to the process be separated the chloro-4-bromophenol of 2-, change the method that traditional rectifying is separated, the fusing point utilizing the chloro-4-bromophenol of 2-is 46 DEG C, the fusing point of impurity 43 DEG C, the fusing point of two kinds of materials is different, and replace rectifying column removing impurities with crystallization kettle, equipment is simple, energy consumption is low, easy to operate.
Heater layering in crystallization kettle in crystallisation phenol separation equipment is evenly arranged, when ensureing that heating melts to greatest extent, and the uniformity that material is heated; Fin is arcuation, can increase the heating surface (area) (HS of fin further, and fin is relative between two, is convenient to be fixed on heating tube in groups, evenly heats material; The temperature of material can be shown by temperature sensor and temperature indicator better, facilitate timely control heater being carried out to temperature.
The air in crystallization kettle can be got rid of when the material of crystallisation phenol separation equipment adds crystallization kettle by feed pipe, facilitate charging.The liquid level gauge be arranged on crystallization kettle more clearly shows the situation that material adds, and carries out the operation opened or closed of charging in time.
