Description

Solid alkali waste material dissolving device Technical Field The utility model relates to a solid alkali waste dissolving device, in particular to a structure of the solid alkali waste dissolving device. Background The chlor-alkali industry refers to the chemical industry of preparing solid alkali (sodium hydroxide), chlorine and hydrogen and a series of products derived from the solid alkali (sodium hydroxide), by using an electrolysis saturated sodium chloride solution, and the products are widely applied to the fields of chemical industry, light industry, textile industry, metallurgical industry, petrochemical industry and the like. The production process of the solid alkali comprises the steps of firstly heating 32% of liquid alkali in a falling film evaporator for evaporation, concentrating to 60% concentration, then adding the liquid alkali into the falling film evaporator, and indirectly heating alkali liquid by using high-temperature molten salt at 410-430 ℃ to gradually evaporate and reduce water to obtain a high-concentration sodium hydroxide solution. Then, adding the high-concentration sodium hydroxide solution into a nickel-containing cast iron pot, further evaporating and concentrating to obtain molten anhydrous sodium hydroxide, and finally directly adding the molten sodium hydroxide into a flaker or a granulating tower to prepare flaky or granular solid alkali. In production, because the feed inlet, the discharge outlet and the pipeline interface of the equipment are not tightly sealed, and the pipelines are corroded and damaged, some solid alkali waste materials which fall to the ground can be generated, and in addition, a part of solid alkali waste materials can be generated when the equipment is started and stopped and maintained. If the solid alkali waste is directly discharged, the solid alkali waste not only pollutes the environment, but also causes raw material waste and increases the enterprise cost.
