Description

Technical Field

[0001] This utility model relates to the field of chemical equipment manufacturing, specifically to a condenser for a reactor internal to a synthetic ammonia tower. Background Technology

[0002] Ammonia synthesis towers are typical exothermic devices, such as those used in the Haber process for ammonia synthesis. To address the high-temperature gases generated during the reaction and achieve rapid cooling of the top of the inner cavity of the outer cylinder, a condensation gas system is installed. The condenser is part of this system and is typically located below the cover plate. Currently, the traditional condenser structure is a fixed connection, positioned above the first-stage heat exchanger. The problem is that when the first-stage heat exchanger expands due to heat, it undergoes axial displacement, causing its top to contact the condenser, resulting in structural deformation and damage. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a condenser for the reactor internals of a synthetic ammonia tower, which changes the fixed connection method to a movable connection, effectively solving the problem of top contact caused by the expansion displacement of the first-stage heat exchanger.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A condenser for the reactor internals of an ammonia synthesis tower includes a condensation box, a loose flange, and a movable mounting mechanism. The condensation box is located below a cover plate and is fitted around a central tube. One end of the condensation box is fixedly connected to an inlet bend connecting to a vertical pipe, and the other end is connected to the movable mounting mechanism. Circular holes are evenly distributed on the inner circumferential surface of the condensation box. Condensed gas passes through the vertical pipe and the condensation box, and overflows through the circular holes.

[0006] The vertical pipe is slidably connected to the cover plate via a loose flange, and the upper end of the loose flange is connected to the condenser inlet pipe.

[0007] The movable hanging mechanism includes a connecting plate and a hanging ear. The hanging ear is fixedly connected to the cover plate and has a vertical strip hole. The connecting plate is connected to a sliding pin, which is slidably connected to the strip hole.

[0008] Furthermore, the lug is provided with a vertical connecting groove, and symmetrical vertical strip holes are provided on both sides of the groove. The connecting plate is set vertically, with its lower end fixedly connected to the condenser box, and its upper end threadedly connected with a horizontal sliding pin. After the connecting plate is inserted into the connecting groove, the sliding pin passes through the two strip holes and the connecting plate. When the condenser box moves upward, the sliding pin moves upward, and the strip holes play a limiting role.

[0009] Furthermore, the cover plate is provided with a T-shaped slot, into which the lower end of the loose flange is inserted; furthermore, a vertical limiting guide rod is threaded into the slot, which can pass through the flange hole of the loose flange for guiding and limiting.

[0010] Furthermore, the upper end of the loose flange is fixedly connected to the condenser inlet pipe, and the upper end of the condenser inlet pipe is connected to a side inlet pipe, which is equipped with an expansion joint.

[0011] Furthermore, the condenser box has a circular or square ring shape when viewed from above.

[0012] Furthermore, an inclined surface is provided on the inner side of the lower end of the condenser box, and an annular support platform is provided on the upper end of the first-stage heat exchanger. The outer side of the annular support platform is provided with a slope with the same inclination as the inclined surface of the condenser box. This structural design makes the displacement of the first-stage heat exchanger more stable when it comes into contact with the condenser box.

[0013] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonably designed. When the condenser box is under pressure, it can be displaced upward by a certain distance through the loose flange and movable bracket mechanism, which effectively solves the problem of component deformation and damage caused by the top contact of the first-stage heat exchanger due to expansion displacement.
