Description
Technical Field
The utility model belongs to the technical field of the evaporation crystallization, concretely relates to install defoaming device in DTB crystallizer.
Background
DTB is an abbreviation for Draft Tube Baffle (crystalizer) and stands for Draft Tube and Baffle. The DTB crystallizer belongs to a typical crystal slurry internal circulation flash crystallizer, and because a guide shell is arranged in the crystallizer to form an internal circulation channel, the crystal slurry has good mixing conditions, good circulation can be realized in the crystallizer only by a very low pressure head, high rotation speed is maintained on each flow section, and the concentration of the crystal slurry can reach 30-40% (by weight). The method can quickly reduce the supersaturation degree of a boiling interface in evaporative crystallization, so that the supersaturation degree of the solution is in a lower level, and the method is particularly suitable for materials with a steeper solubility curve.
The defoaming device is a key component of the DTB crystallizer. The capacity of the DTB crystallizer is essentially dependent on the flash intensity. Improve the flash strength of DTB crystallizer, the gas velocity that can make the secondary steam becomes high, at this moment, can appear a large amount of foams in the secondary steam and smuggle secretly, if not handling, the secondary steam can take a large amount of materials to get into next device, can make the interior magma concentration of DTB crystallizer step-down on the contrary, and the crystallization capacity diminishes, and the crystallization time prolongs greatly to the productivity effect that makes the DTB crystallizer reduces.
Therefore, it is necessary to design a defoaming device which can effectively eliminate entrainment in the secondary steam and can be used for a long time.
Disclosure of Invention
The utility model provides an above-mentioned problem, a install defoaming device in the DTB crystallizer is provided, the utility model discloses simple structure can use for a long time, can eliminate the mist foam among the secondary steam well and smuggle secretly. The utility model discloses technical scheme as follows:
a defoaming device arranged in a DTB crystallizer comprises 12 swirl vanes, a guide cylinder and a liquid receiving plate; the inner edge of each cyclone blade is fixed on the cylinder body of the guide cylinder, the cyclone blades are uniformly distributed, the outer edge of each cyclone blade is fixed on the cylinder body of the DTB crystal, each cyclone blade is of a planar structure, the included angle between each cyclone blade and the horizontal plane is 15 degrees, each cyclone blade is of a smooth surface, and the bottom of the guide cylinder is fixedly connected with the liquid receiving plate; liquid outlet holes are distributed on the cylinder body of the guide cylinder, every three adjacent liquid outlet holes are distributed in a regular triangle, and the diameter of each liquid outlet hole is 3-8 mm; the center distance between every two adjacent liquid outlet holes is 20 mm.
On the basis of the technical scheme, the diameter of the guide shell is 400mm, and the height of the guide shell is 150 mm.
On the basis of the technical scheme, the diameter of the liquid outlet hole is 5 mm.
On the basis of the technical scheme, the liquid receiving plate is of a concave structure, and liquid can flow out of the liquid outlet hole conveniently due to the structure.
On the basis of the technical scheme, the inner edges of the rotational flow blades are fixed on the cylinder body of the guide cylinder through bolts, and the outer edges of the rotational flow blades are fixed on the cylinder body of the DTB crystal body through bolts. This structure can be dismantled when the whirl blade damages and change.
Compared with the prior art, the utility model has the following advantage:
through the foam eliminating device, the mist in the secondary steam forms liquid drops on the surfaces of the rotational flow blades; because the swirl vanes are smooth surfaces, the droplets fall back into the slurry due to gravity. The utility model discloses simple structure can use for a long time, can eliminate the foam among the secondary steam well and smuggle secretly.
