Description

Technical Field

[0001] The utility model relates to the technical field of alkali production, in particular to combined alkali production equipment. Background Art

[0002] Combined alkali production is a process of producing soda ash with sodium chloride, carbon dioxide, ammonia and water as raw materials, and producing ammonium chloride as a by-product. Soda ash is a basic chemical raw material with a large amount of use and an important position in the national economy. Ammonium chloride is mainly used as agricultural fertilizer, but its quality affects the development of the soda ash industry. The "combined alkali production process" is also known as the "Hou's alkali production process". The alkali production process uses salt, ammonia and carbon dioxide as raw materials, and utilizes the chemical reaction between these raw materials under certain conditions to produce soda ash. The most representative ones are the ammonia-soda process and the combined alkali production process. The ammonia-soda process, also known as the Solvay alkali production process, is named after the Belgian Solvay who successfully produced sodium carbonate in 1862 using salt, ammonia and carbon dioxide as raw materials.

[0003] A combined alkali production equipment disclosed in the Chinese utility model patent application disclosure CN202355948U is specifically a combined alkali calcining and dust removal device. It includes a calcining furnace, the outlet of the calcining furnace is equipped with a collective buried scraper, and the outlet of the collective buried scraper is equipped with a slope buried scraper. It is characterized in that: an induced draft duct is installed at the outlet of the collective buried scraper and the slope buried scraper, the outlet of the induced draft duct is connected to the inlet of the bag dust collector, the discharge port of the bag dust collector is equipped with a spiral stirring cage, the outlet of the spiral stirring cage is connected to the slope buried scraper through a pipeline, the upper part of the bag dust collector is equipped with an exhaust duct, the exhaust duct is connected to the exhaust fan, and the outlet of the exhaust fan is equipped with an emptying pipe. The utility model has a simple structure and is easy to use. It can prevent the combined alkali calcining device from carrying gas, reduce the flying of alkali dust, recover soda ash products, and reduce costs.

[0004] However, the device lacks the function of calcining and cooling alkali in a closed environment. When in use, it cannot be closed for calcining and cooling alkali, resulting in a large amount of material volatilization during the alkali production process, resulting in a waste of resources. Not only that, the device also lacks the function of observing the alkali calcination temperature. When in use, the staff cannot observe the temperature of the calcination process, resulting in the inability to control the temperature changes in time. Utility Model Content
