The invention relates to a hydrocyanic acid oxidation reactor and a tube plate cooling structure thereof. The tube plate cooling structure comprises an upper tube plate and further comprises a cooling structure body used for cooling the upper tube plate, the cooling structure body comprises an annular tube, and a water inlet tube used for conveying cooling liquid into the annular tube is arranged on the outer wall of the annular tube in a manner of being communicated with the annular tube; and the cooling structure further comprises a first cooling mechanism and a second cooling mechanism which are arranged on the annular tube, the first cooling mechanism is used for cooling the periphery of one face of the upper tube plate, and the second cooling mechanism is used for cooling the center position of one face of the upper tube plate. The tube plate cooling structure has the advantage of preventing the upper tube plate from being damaged due to too high steam temperature.
Description
technical field [0001] The application relates to the field of hydrocyanic acid reaction equipment, in particular to a hydrocyanic acid oxidation reactor and a tube sheet cooling structure thereof. Background technique [0002] Many chemical products synthesized from hydrocyanic acid are widely used in the fields of medicine, food, feed, electroplating, metallurgy, polymers, expenses and fine chemicals. Therefore, it is very important to study the synthesis method, extended processing and comprehensive utilization of hydrocyanic acid. Important; the existing industrial synthesis of prussic acid is mainly produced by Angle's method, and prussic acid reactor is the core device in the production process of prussic acid. [0003] Authorized announcement number is that the Chinese patent of CN212855693U discloses a kind of internal structure of hydrocyanic acid reactor device, comprises reactor housing, is respectively provided with upper tube plate and lower tube plate at the up...
