Embodiment Construction

[0018] The present invention will be further described below using the accompanying drawings and examples.

[0019] refer to Figure 1-11 , The high-efficiency internal circulation evaporation separation tower of the present invention includes a cylinder body 6, and the cylinder body 6 is composed of an upper cylinder and a lower cylinder. The upper end of the cylinder body 6 is fixedly connected with the upper head 7 , and the lower end of the cylinder body 6 is fixedly connected with the separator 1 . There are at least three circulation heating blocks accumulatively installed in the barrel 6, which are respectively the accumulated circulation heating lower block 2, circulation heating middle block 3 and circulation heating upper block 4, and are placed between the cylinder body 6 and the head 7. There is a demister 5. The lower end of the separator 1 is respectively provided with a first temperature measuring port g1, a sampling port g2, and a concentrated material ...

Abstract

The invention discloses a high-efficiency internal circulation evaporation separation tower which is characterized in that the upper end of a barrel is fixedly connected with an upper seal head; the lower end of the barrel is fixedly connected with a separator; at least three circulation heating blocks are accumulatively arranged in the barrel; a demister is positioned between the barrel and the upper seal head; a first temperature measurement opening, a sampling opening and a concentrated material outlet are formed at the lower end of the separator; a vapor inlet is formed at the upper layer circulation heating block and in the barrel; a vapor outlet is formed at the bottom layer circulation heating block and in the barrel; a material inlet is formed at the upper end of the upper layer circulation heating block; a manhole, a first sight glass opening, and a second sight glass opening are formed in the barrel; a first liquidometer and a second liquidometer are arranged on the barrel; and a gas outlet, a second temperature measuring opening and a pressure measuring opening are formed at the upper end of the upper seal head. The separation tower has the advantages of compact and reasonable structure, low height, small floor area, high separation concentration efficiency and product purity, good quality, energy conservation and environment friendliness, simplicity in operation, use cost saving, safety in use and the like.

Description

technical field [0001] The invention relates to a concentration device for hydrochloric acid separation, magnesium fluorosilicate, hydrocyanic acid and other chemical raw materials, and is a high-efficiency internal circulation evaporation separation tower. It can concentrate and separate various salt media with high viscosity and easy crystallization. Background technique [0002] Existing evaporation and concentration devices generally need to include a first-effect evaporator, a second-effect evaporator, a three-effect evaporator and a dryer to evaporate, concentrate and dry materials step by step. The disadvantages of the device are small capacity and high energy consumption. , the cost is high, and the device occupies a large area, and a factory building of about 100 square meters needs to be built. The evaporation section of the three-effect evaporator is 4 meters high, which greatly occupies the space of the factory building, and the production efficiency is low. For...
