Description

Technical Field

[0001] The utility model relates to the field of cyanogen chloride production, in particular to a high-yield nozzle reaction device. Background Art

[0002] Cyanogen chloride is produced by the sodium cyanide method, which is mainly synthesized by reacting sodium cyanide and chlorine. The specific production process is: first, add a suitable amount of water to a 30% sodium cyanide solution to form a sodium cyanide aqueous solution, and its mass fraction needs to be controlled at 15%. Then, the prepared 15% sodium cyanide aqueous solution is heated with liquid chlorine to convert it from liquid to pressurized gas. At the same time, sodium cyanide and chlorine are mixed in a certain proportion through a special nozzle and then fed into a cyanogen chloride reactor to react to generate cyanogen chloride monomer.

[0003] At present, after chlorine gas and sodium cyanide liquid enter the interior of the cyanogen chloride reactor through a nozzle, they instantly contact and react to generate cyanogen chloride gas and sodium chloride aqueous solution. The chlorine gas feed pipe is arranged at the top of the cyanogen chloride reactor, and the sodium cyanide liquid is placed on the side of the cyanogen chloride reactor. The chlorine gas and the sodium cyanide contact on the same plane, and the sodium cyanide collides with the chlorine gas in the opposite direction. The existing defect is that since the diameter of the sodium cyanide feed pipe is more than 10 mm, it is difficult for chlorine gas and sodium cyanide to completely contact and react, resulting in excessive sodium cyanide, which enters the wastewater, increasing the difficulty of wastewater treatment, and wasting economic costs.
