Device for producing magnesium chloride from brine

Abstract

The invention discloses a device for producing magnesium chloride from brine. The device comprises a brine tank, a concentrator and a granulation tower; an arranged preheating pool can be used for heating brine to complete preheating operation of the brine, and the preheating is carried out by adopting tail gas obtained after combustion, so that the utilization rate of energy is increased; a spiral tube is arranged at a steam outlet of a shell, so that the preheated brine can be subjected to heat preservation, and then concentration work of the brine can be well completed; a liquid inlet pipeand an air inlet pipe of a granulation tower are not at a same place, so that air in the air inlet pipe has sufficient wind power to enter the tower body, and then the granulation effect is good; andan arranged separation pipe communicates with the air inlet pipe, and then the air inlet pipe can generate certain suction force to the separation pipe when the air enters the granulation tower from the air inlet pipe, so that powder in a discharging pipe can be sucked into the air inlet pipe, and therefore, separation work can be completed without additionally arranging other devices. The overallstructure is simple, and production cost and use cost are reduced.

Description

technical field [0001] The invention relates to the technical field of equipment for producing magnesium chloride from brine, in particular to a device for producing magnesium chloride from brine. Background technique [0002] There are many useful substances in the brine, and in order to extract the useful substances in the brine, it is often necessary to concentrate the brine. At present, the existing concentration equipment cannot preheat the brine, so new preheating equipment needs to be added, which not only increases the investment cost, but also increases the cost of using the newly added preheating equipment, which is not conducive to the production needs of enterprises . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for producing magnesium chloride from brine, which can preheat brine, reasonably utilize energy, and reduce production costs of enterprises. [0004] In order to solve the above-...
