Example Embodiment

[0024] figure 1 This is a schematic diagram of the preparation device of an embodiment of the present invention. In the schematic diagram, there are 2 reaction chambers and 2 preheating chambers. Since the design and principle of the device with more reaction chambers and preheating chambers are similar, it is no longer in the present invention. List one by one. The preparation device includes: a fluidized bed reactor 10, a solid feeder 20, a gas-solid separator 30, a gas preheater 40, and multiple connecting pipes.

[0025] The fluidized bed reactor 10 includes four longitudinally arranged fluidization chambers and baffles 101, wherein the four fluidization chambers serve as two preheating chambers 11 and two reaction chambers 12, respectively, the preheating chamber 11 and the reaction chamber 12 are arranged alternately, and each adjacent preheating chamber 11 and the reaction chamber 12 are separated by a baffle 101.

[0026] The fluidized bed reactor 10 also includes a gas d...

Abstract

The invention discloses a preparing device and method for ammonia gas. The preparing device is used for preparing ammonia gas through a reaction of ammonium chloride and granular inorganic salt. The preparing device comprises a fluidized bed reactor, the fluidized bed reactor is provided with at least two fluidized chambers, one fluidized chamber is a preheating chamber which is used for heating the granular inorganic salt, another fluidized chamber is internally provided with at least one atomizing spray nozzle, and the granular inorganic salt forms a fluidized bed layer and is in contact with an aqueous ammonium chloride solution in the reaction chamber for a reaction to generate the ammonia gas; the granular inorganic salt can sequentially flow through multiple preheating chambers and reaction chambers under pushing of density difference of the granular bed layer, and the required conversion rate is finally reached. By means of the preparing device and method, a new idea for preparing the ammonia gas from ammonium chloride is put forward, the reaction step is simplified, and the reaction efficiency is improved.

Description

technical field [0001] The present application relates to the field of inorganic salt and soda ash chemical industry, in particular to a preparation device and method for ammonia gas. Background technique [0002] The soda ash industry produces a large amount of by-product ammonium chloride, which has become the bottleneck of the soda ash industry due to the restrictions on the application of fertilizers, and it is urgent to find a suitable utilization method. If ammonium chloride is decomposed into NH with higher economic value 3 and HCl, NH 3 It can be recycled in the soda ash industry, and HCl can also be used in many fields such as organic chlorination. Therefore, ammonium chloride is decomposed to produce NH 3 And HCl is a good way to solve the bottleneck problem of soda ash industry. [0003] Ammonium chloride can be decomposed into NH by heating 3 and HCl, but at the same time a large amount of ammonium chloride is sublimated, and the generated NH 3 It is difficu...
