AI Technical Summary

Problems solved by technology

In this patented technology, the power for the float to slide up and down comes directly from the stirring device. When the stirring is strong, the liquid level fluctuates greatly, which is good for the float to slide up and down, but strong stirring is not good for the growth of crystals. When the stirring is slow, the liquid level fluctuates small and the float The sliding range is small, it is difficult to effectively slide the entire length of the outer wall of the cooling tube, and the cooling tube that is not scraped will be wrapped by crystals, which will affect the crystallization efficiency

Embodiment Construction

[0015] The present invention will be described in further detail below by way of implementation and accompanying drawings:

[0016] The new casing crystallizer includes a shell 1, a head 2, and a refrigerant tube bundle 3. The head 2 is located on the top of the shell 1 and is connected with the shell 1 to form an airtight container. The shape of the airtight container can be round or square. The refrigerant tube bundles 3 are uniformly arranged through the head 2 and extend to the container. bottom.

[0017] The refrigerant tube bundle includes a plurality of vertical sleeves 4 , a tube plate 5 , a tube cap 6 , a shift fork 7 , an annular scraper 8 , a long shaft 9 and a driving device 10 . A plurality of vertical bushings 4 are centered on the long axis 9 and evenly distributed around the periphery with the arm length of the shift fork 7 as the radius. The inner tube of each vertical bushing 4 is connected to the refrigerant inlet through one side of the cap 6 , the outer ...

Abstract

The invention discloses a sleeve type crystallizer. The sleeve type crystallizer comprises a shell (1), an end socket (2) and a refrigerant tube bundle (3), wherein the end socket (2) is connected with the top of the shell (1) and forms a sealed container (16) with the shell (1); a solution inlet (13) is arranged at the upper part of the shell (1); a solution outlet (14) is arranged at the lower part of the shell (1); the refrigerant tube bundle (3) is mounted inside the sealed container (16). With the adoption of the sleeve type crystallizer provided by the invention, the defect in the prior art that the crystallization efficiency is influenced since a cooling pipe is coated with a crystal can be overcome.

Description

technical field [0001] The invention relates to a crystallization device, in particular to a casing type crystallizer. Background technique [0002] Crystallization is one of the most basic chemical processes. The cooling saturated solution method is one of the commonly used crystallization methods, using the principle that the solubility of the solvent to the solute increases with the increase of the temperature, and decreases with the decrease of the temperature, and cools the hot saturated solution to make the solute in the solution Precipitation and separation from the solvent in the state of crystals. Crystallizers are widely used in petrochemical, chemical fertilizer, plastic, rubber, pharmaceutical industries, etc. in the process of cold crystallization. [0003] Patent No. ZL200520035202.6 "Hydrazine Hydrate Oxidation Liquid Concentrated Crystallization Kettle" discloses a crystallization device, including a kettle cover, a kettle body, a discharge valve installed ...
