    The invention relates to the equipment of plants for the continuous production of hydrocyanic acid, in particular to a cooling head for a single or multi-chamber furnace for the continuous production of hydrocyanic acid.
    The purpose of the invention is to increase the efficiency of the production of hydrocyanic acid.
    FIG. 1 shows a cooling head, about 1; FIG. 2 is also a vertical section; in fig. 3 is a sectional view, in FIG. 4 - bottom head plate, cut; in fig. 5 - the same, top view; in fig. 6 shows the placement of pipes with a single burner; FIG. 7 - the same, with two burners.
    The cooling head comprises a housing 1, a bottom plate 2, a device 3 for receiving the target gas product. The head is placed above the furnace 4, in which reaction tubes 5 with a catalyst are placed, a hollow shpind 6 placed above the top plate 7 for sealing the suspended reaction tubes 5. The gland 8 is located at the mounting points of the tubes 5 and is provided with a gasket 9 housed in the shell 10. Inside the housing 1 there is a tubular element 11 fixed in the upper and lower plates, nozzles for inlet 12 and outlet 13 for the cooling medium and placed coaxially around each reaction tube of the casing 14. The tubes of the tubular element are sore, inyens with reactive t rubles through the gland 8.

    A series of experiments was carried out in a single-chamber furnace for the continuous production of hydrocyanic acid. By the interaction of ammonia and methane in a ratio of 1.05: 1 with a heating system equipped with 26-66 suspended reaction tubes. It is established that an increase in the number of reaction tubes in the known construction of the cooling head leads to a slight increase in productivity, but is associated with an increase in the consumption of heat energy and an increase in the process temperature above the allowable limit. The increase in the number of reaction tubes in the proposed design of the cooling tube can significantly reduce the consumption of heat energy and process temperature, increasing the efficiency of the production process. Claims of the invention A cooling head for a single or multi-chamber furnace for the continuous production of hydrocyanic acid, comprising a housing with a tubular element housed therein, fixed in the upper and lower plates and equipped with connections for inlet and outlet of the cooling medium, the tubes of which are connected to the reaction tubes in the bottom plate of the cooling head, characterized in that, in order to increase the efficiency of the process, it is equipped with tubular kozhzpsam, placed in the bottom plate of the cooling head The connection between the gland is coaxial around each packing to the height of its cylindrical part.
