A continuous high-efficiency industrial salt dissolving device and its operating method

Abstract

The invention discloses a continuous high-efficiency industrial salt dissolving device, which includes a salt silo and a mixing tank, the discharge port of the salt silo is connected to the mixing tank, and also includes a star-shaped feeder, a screw crusher, a salt water ratio regulating valve, and a salt slurry The pump, the first pipeline dissolver and the second pipeline dissolver, the discharge port of the salt silo is connected to the inlet of the screw crusher through the pipeline, and the pipeline between the salt silo and the screw crusher is equipped with a star feeder, the screw The outlet of the crusher is connected to the feed port of the mixing tank, and the feed port of the mixing tank is also connected to the water inlet pipe. pipeline dissolver, and a salt slurry pump is provided on the connecting pipeline between the mixing tank and the first pipeline dissolver, and the discharge pipe of the pipeline dissolver leads to the soda making workshop; the invention also discloses the operation method of the device; The invented product saves cost, reduces land occupation, continuously supplies brine, and the ratio of salt and water is coordinated, which is suitable for all large alkali plants.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to a dissolving device, in particular to a continuous high-efficiency industrial salt dissolving device and an operating method thereof. Background technique [0002] At present, alkali plants dissolve by adding a rough amount of salt into the tank for stirring. This method is acceptable for small alkali plants, but for large alkali plants, due to the huge amount of salt water used, it requires a large amount of preparation Large-scale salt-dissolving tanks or tanks not only occupy a lot of land and are expensive, but also salt impurities will accumulate at the bottom of the tank, causing salt scales to form in the tank, resulting in frequent cleaning of the salt-dissolving tank, affecting production and increasing labor for workers At the same time, the proportion of brine cannot be strictly controlled, which directly affects the output of alkali and product quality.

Problems solved by technology

[0002]Currently, alkali plants dissolve by adding a rough amount of salt into the tank for stirring. This method is acceptable for small alkali plants, but for large alkali plants As far as the factory is concerned, due to the huge amount of salt water used, it is necessary to prepare a large number of large-scale salt-dissolving tanks or tanks, which not only occupy a lot of land and are expensive, but also salt impurities will accumulate at the bottom of the tank, resulting in the formation of salt scale in the tank, resulting in The salt dissolving tank needs to be cleaned frequently, which affects production and increases the workload of workers; at the same time, the proportion of brine cannot be strictly controlled, which directly affects the output of alkali and product quality

[0003] Chinese patent CN2580302 discloses "Large Boiler Automatic Stirring Salt Dissolver". This patent provides a large boiler automatic stirring salt dissolving equipment. Although this equipment can achieve automatic stirring and rapid salt dissolution, the salt dissolution rate is still not up to 100%, and it takes a long time to dissolve salt, often a lot of water is wasted

[0004] Chinese patent CN101703899A discloses a "mixing dissolver". The mixing dissolver includes a mixing section, and the rear end of the mixing section is connected to the dissolving section. Good performance, simple operation, low pressure, easy maintenance, not easy to scar, etc.; however, this kind of mixing dissolver is limited in the amount of dissolution, and the amount of medium is large, and scarring will occur; and the proportion of the medium cannot be automatically adjusted, so it is not suitable for large quantities medium continuous dissolution
