Description

Technical Field

[0001] The utility model relates to the technical field of brine separation, in particular to a high-concentration brine and low-cost brine separation device. Background Art

[0002] Methods for separating salt and water: Evaporation crystallization method: heat the salt water to evaporate the water, so that the salt crystallizes, and finally achieves the separation of salt water; distillation method: collect steam and condense it into water. The residue left after the salt water is dried is the salt; cooling crystallization method: first heat the solution, evaporate the solvent to form a saturated solution, then lower the solution temperature, the solubility of the salt will decrease, and the salt will precipitate as crystals. Most of the existing methods use evaporation crystallization;

[0003] For example, announcement number: CN218665476U, named "A salt water separation device", through the installation of stepped evaporation plates, when the salt water passes through the upper surface of the evaporation plate, when too much salt water is added inside the evaporation plate, it will flow to the side of the side plate and effectively flow to the upper surface of the next evaporation plate, effectively adding the same amount of salt water to the evaporation plates at each position, and solving the problem that the existing device uses a pump to quantitatively extract salt water and add it to the evaporation plate. Since the evaporation plate is placed vertically, less salt water is collected on the evaporation plates at the middle and bottom positions, further leading to reduced evaporation efficiency.

[0004] The above-mentioned existing brine separation device adopts a stepped flow method to improve the uniformity of the brine evaporation process. However, when the stepped structure flows from top to bottom, the brine will splash, causing partial brine loss and increasing cost losses. In addition, the use of a motor to drive the heating tube to rotate will increase the energy consumption of the equipment, causing the cost to further increase. Therefore, it does not meet the existing needs. We have proposed a high-concentration brine and low-cost brine separation device. Utility Model Content

In addition, the use of a motor to drive the heating tube to rotate will increase the energy consumption of the equipment, resulting in further cost increases.

[0015] 1. The utility model is provided with a brine separation table, a first evaporation plate, a second evaporation plate, a third evaporation plate, a fourth evaporation plate, a connecting channel, a spiral heating tube, and a strip heating tube. Compared with a stepped brine separation device, the evaporation plates of the brine separation device are all in the same horizontal plane. The material is fed at the first evaporation plate, and the liquid flows along the connecting channel to the second evaporation plate, the third evaporation plate and the fourth evaporation plate. The brine is evenly covered, and there is no splashing problem during the flow, thereby reducing cost losses. A spiral heating tube is used to heat and evaporate the brine in each evaporation plate. Since the heating tube is a spiral structure, its coverage area is uniform. Part of the brine located in the connecting channel is heated and evaporated by the strip heating tube. Compared with the method of driving the heating tube by a motor, the heating structure directly acts on the bottom of the plate body, does not require motor drive, and reduces costs.

Specifically, the placement plate is lifted upward to move the inner lifting frame outward from the outer frame. After moving to the required height, the insertion rod is inserted into the insertion hole to limit the inner lifting frame to the height. By adjusting the height of the placement plate, the distance between the upper brine separation table and the first evaporation plate can be shortened, so that the feed pipe is not prone to splashing when the material falls into the first evaporation plate.
