Problems solved by technology
[0004] Aiming at the deficiencies in the prior art, the present invention provides a device for crystallizing magnesium sulfate at low temperature in the desulfurization circulating liquid, which solves the problem that the circulating liquid in the desulfurization tower is used for cooling and crystallizing the magnesium sulfate solution because the temperature of the circulating liquid is not low enough. It will affect the effect of magnesium sulfate crystallization, so that the crystallization of magnesium sulfate solution is not sufficient. After the crystallization of magnesium sulfate is completed, it is inconvenient to collect the crystals of magnesium sulfate

The invention discloses equipment for crystallizing magnesium sulfate from desulfurization circulating liquid at a low temperature. The equipment comprises a desulfurizing tower and a crystallizing tower, wherein an accommodating cavity is formed between the desulfurizing tower and the crystallizing tower; a liquid inlet pipe is embedded into one side of the lower part of the desulfurizing tower,one end of the liquid inlet pipe is embedded into the lower surface of the accommodating cavity and is fixedly connected with a coiled pipe, one end of the coiled pipe is fixedly connected with a liquid outlet pipe, and one end of the liquid outlet pipe respectively penetrates through the upper surface of the interior of the accommodating cavity and one side surface of the upper part of the crystallizing tower. The invention relates to the technical field of magnesium sulfate crystallization. The invention discloses the equipment for crystallizing the magnesium sulfate from the desulfurizationcirculating liquid at the low temperature. An annular driven bevel gear is fixedly connected to the position, located on the periphery of the liquid outlet pipe, of the upper surface of a first circular cavity. When a magnesium sulfate solution is cooled and crystallized, a conveying pipe can stir the magnesium sulfate solution under the rotation of a motor, so that the circulating liquid in theconveying pipe stirs the magnesium sulfate solution, and the magnesium sulfate solution is cooled more sufficiently.
Description
technical field [0001] The invention relates to the technical field of magnesium sulfate crystallization, in particular to a device for low-temperature crystallization of magnesium sulfate from a desulfurization circulating liquid. Background technique [0002] Magnesium sulfate is a compound containing magnesium. Anhydrous magnesium sulfate is a commonly used chemical reagent and drying reagent. Magnesium sulfate can be used in tanning, explosives, papermaking, porcelain, fertilizer, and oral laxatives in medical treatment. Magnesium sulfate is used as a fertilizer in agriculture, because magnesium is one of the main components of chlorophyll, and it is usually used in potted plants or magnesium-deficient crops. Compared with other fertilizers, magnesium sulfate has the advantage of higher solubility. Magnesium sulfate is also It is used as a bath salt. When processing magnesium sulfate solution, the circulating liquid sprayed in the desulfurization tower is often used to m...
