DETAILED DESCRIPTION

[0022] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further explained below with the help of drawings and examples. It should be explained that the examples and features in the examples of the present application can be combined with each other without conflict.

[0023] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other ways not described herein, and the present application is not limited to the specific embodiments described below.

[0024] Embodiment one

[0025] As shown in Figures 1-5 The utility model provides a hydrogen bromic acid production condensing equipment, including condensing pipe 1, one end of condensing pipe 1 is provided with inlet pipe 2, the other end of condensing pipe 1 is provided with liquid discharge pipe 3, the bottom of inlet pipe 2 is connected with flange one 7, the bottom surface fixedly connected with chute cylinder two 13 of flange one 7, the bottom of flange one 7 is below and is provided with flange two 11, the top surface fixedly connected with chute cylinder one 12 of flange two 11, the inclined plane of chute cylinder one 12 and chute cylinder two 13 are mutually inlayed, and form the tapered inlaying of the shrinkage upwards, and the outer periphery of flange one 7 and flange two 11 is surrounded with tight pipe hoop 6, one end of tight pipe hoop 6 is fixedly connected with screw seat 17, the other end of tight pipe hoop 6 is provided with rounded rectangular groove 18, the inner side wall of screw seat 17 is threadedly connected with screw two 16, one end of screw two 16 penetrates rounded rectangular groove 18 and is fixed through the nut, and the inner periphery of tight pipe hoop 6 is sequentially provided with sealing ring one 14 and sealing ring two 15 from outside to inside.

[0026] Traditional in condensing device will two flanges directly butt joint up and down, and the sealing gasket is arranged between the two flanges, and the flange hole is directly arranged on the surface of the flange plate, and the sealing is fixed by the screw from the top and bottom,

[0027] The specific settings and effects of the embodiment will be described below. The technical solution changes the original flange plate into flange one 7 and flange two 11, and a pipe clamp 6 is additionally arranged between the flange one 7 and the flange two 11 for fixation. The pipe clamp 6 is arranged at the outer periphery of the flange one 7 and the flange two 11, so that the fastening position is transferred from the upper and lower adhered surfaces to the outer periphery. Since the sealing ring one 14 and the sealing ring two 15 are made of rubber material, they are easily corroded after being in contact with hydrobromic acid. After being transferred to the outer periphery, the probability of direct contact with hydrobromic acid is smaller, which greatly improves the service life and the sealing safety of the condensing equipment. Meanwhile, the flange one 7 is arranged below the chute cylinder two 13, and the flange two 11 is arranged above the chute cylinder one 12 which has a shape corresponding to the chute cylinder two 13. When the flange one 7 and the flange two 11 are connected, the gap formed by the chute cylinder one 12 and the chute cylinder two 13 is inclined upward and inward. After the hydrobromic acid is evaporated from the stirring equipment, the hydrobromic acid gas flow is formed from the lower to the upper of the gas inlet pipe 2. The embedding openings of the chute cylinder one 12 and the chute cylinder two 13 are upward, which is the same as the flowing direction of the gas flow. Therefore, the hydrobromic acid gas flow cannot spontaneously penetrate from the gap between the chute cylinder one 12 and the chute cylinder two 13. Meanwhile, according to Bernoulli's principle, the fluid formed at the joint of the flange one 7 and the flange two 11 will form negative pressure at the gap between the chute cylinder one 12 and the chute cylinder two 13, so that the air in the cavity between the pipe clamp 6 and the chute cylinder two 13 is sucked away, and the sealing ring two 15 is recessed inward. These negative pressures will further increase the adhesion of the sealing ring one 14 to the flange one 7 and the flange two 11, and further improve the sealing effect.
