Figs. 1-2The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

The reaction vessel 100 has a hollow structure, and the interior of the hollow structure is filled with an insulation layer 200, which is filled with rock wool board. An air inlet pipe 300 is installed inside the reaction vessel 100, which is connected to the exhaust port of an ammonia storage tank. The main purpose of introducing ammonia into the reactor is to produce ammonia brine and to bring the ammonia brine to the concentration required for the carbonation process. This process is a step in the production of soda ash using the ammonia-soda process. Ammonia is introduced into saturated brine, causing it to absorb ammonia and undergo ammonification. The ammonification of ammonia is an absorption process, designed to purify impurities such as calcium and magnesium through ammonification, while simultaneously recovering ammonia from the mother liquor obtained by filtering sodium bicarbonate crystals, ammonia from the tail gas of the carbonation tower, and new replenishing ammonia. This process involves not only ammoniation of brine but also the decomposition of ammonia by microorganisms. Although it mainly takes place under airless conditions, ammoniation directly increases nitrogen nutrients in straw or soil, creating the necessary conditions for nitrification. Many types of microorganisms participate in ammoniation, primarily bacteria. Under suitable conditions, the number of ammonifying bacteria in the soil can reach 10⁵–10⁷ per gram of soil. The lower part of the air inlet pipe 300 is connected to a coil 400, and a support plate 500 is installed at the lower part of the coil 400. The support plate 500 is fixed to the inner wall of the bottom of the reaction tank 100.

A collector 800 is installed inside the reaction tank 100 and directly below the vacuum outlet 700, with an opening at the top. The bottomless conical structure, smaller than the lower opening, is welded inside the reaction vessel 100. This invention can achieve efficient and rapid vacuuming of the reaction vessel 100 through the heating mechanism 600 in conjunction with a vacuum pump. Furthermore, the collector 800 can quickly collect and discharge water vapor, oil vapor, and other high-boiling-point vapors, preventing them from remaining inside the reaction vessel 100.
