Energy-saving sodium chloride crystallization device with uniform heating function

Abstract

The invention relates to an energy-saving sodium chloride crystallization device with a uniform heating function. The device comprises a main body and two heating rods, the device further comprises astirring mechanism and an energy-saving mechanism, the energy-saving mechanism comprises a heat exchange box, two second heat exchange pipes, two first heat exchange pipes, two feeding pipes and two electric valves, and the stirring mechanism comprises a power cylinder, an exhaust pipe, a second bearing, a transmission shaft, a first gear, a second gear, a driving shaft, two first bearings and twocompression blocks. In the energy-saving sodium chloride crystallization device with the uniform heating function, waste heat of the crystallization device can be recycled through the energy-saving mechanism, so energy loss of the crystallization device is reduced, and the energy-saving performance of the crystallization device is improved; and raw materials in the main body can be stirred through the stirring mechanism, so the raw materials are heated uniformly, and the crystallization efficiency of the crystallization device is improved.

Description

technical field [0001] The invention relates to the field of chemical production equipment, in particular to energy-saving sodium chloride crystallization equipment with uniform heating. Background technique [0002] Crystallization equipment, also known as crystallizer, is the equipment used for crystallization operation. Generally, the saturated solution is cooled or evaporated to a certain degree of supersaturation to precipitate crystals. In the process of crystallization of sodium chloride, evaporation crystallization is mainly used. [0003] When the crystallization equipment of the prior art is in the crystallization of sodium chloride, if the solution is heated unevenly, it will cause the liquid to splash due to excessive local temperature, which reduces the safety of the crystallization equipment. Not only that, when sodium chloride is crystallized, The temperature of the generated steam is relatively high. If the steam is discharged directly, it will cause energy ...

[0003] When the crystallization equipment of the prior art is in the crystallization of sodium chloride, if the solution is heated unevenly, it will cause the liquid to splash due to excessive local temperature, which reduces the safety of the crystallization equipment. Not only that, when sodium chloride is crystallized, The temperature of the generated steam is high. If the steam is discharged directly, it will cause energy loss and reduce the energy-saving performance of the crystallization equipment.
