[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figs. 1-3 This utility model provides a technical solution: a device for refining by-product hydrobromic acid and recovering organic raw materials from by-product hydrobromic acid, comprising a housing 1, a gas guide pipe 2 horizontally extending through the outer wall of the housing 1 near the top, and a first partition 3, a second partition 6, and a third partition 7 sequentially welded vertically to the inner wall of the housing 1. The first partition 3 can fix the gas guide pipe 2, and the housing 1 is divided into a cold air chamber 301, a cold water chamber 601, and a recovery chamber 701. The gas guide pipe 2 sequentially extends vertically through the first partition 3, the second partition 6, and the third partition 7. A cold air blower 13 is welded at the center of the top of the housing 1. The model of the air cooler 13 is CBE-23AF, and two air ducts 14 are connected to the side wall of the air cooler 13. The other end of the two air ducts 14 is connected to the air cooling chamber 301. A support plate 9 is welded horizontally at the bottom of the side wall of the housing 1. A support column 10 is welded vertically at the top of the support plate 9. A chilled water circulator 11 is welded to the top of the support column 10. The model of the chilled water circulator 11 is HSD-3W. Two chilled water pipes 12 are connected to the side of the chilled water circulator 11 near the housing 1. The end of the two chilled water pipes 12 away from the chilled water circulator 11 is connected to the chilled water chamber 601.

[0018] Furthermore, a circulation pipe 4 is connected to the bottom of the air guide pipe 2 outside the box 1. The circulation pipe 4 runs horizontally through the box 1, and one end of the circulation pipe 4 inside the box 1 is connected to the air guide pipe 2. An air pump 5 is installed inside the circulation pipe 4 outside the box 1. The air pump 5 can reintroduce the unliquefied organic raw materials into the air guide pipe 2 for multiple condensation treatments.

[0019] Furthermore, a base is welded to the bottom of the box 1 near the edge, and a recycling pipe 8 is vertically installed at the center of the bottom of the box 1. The recycling pipe 8 is used to recycle liquid organic raw materials.

[0020] Furthermore, a drain pipe 15 is connected horizontally on the side wall of the cold air chamber 301 above the chilled water circulator 11. When the cold air turns into liquid, it can be discharged in time through the drain pipe 15.

[0021] Furthermore, the portion of the air duct 2 located within the cold water chamber 601 has an S-shaped structure. The S-shaped air duct 2 can increase the contact area between the air duct 2 and the cold water, thereby improving the condensation effect.

[0022] Furthermore, the air pump 5, the chilled water circulator 11, and the air cooler 13 are all electrically connected to an external power source.

[0023] Working Principle: Gas containing organic raw materials, after initial condensation, enters the device. The air pump 5, chilled water circulator 11, and air cooler 13 within the device are all electrically connected to an external power source. When the power switch is turned on, the air cooler 13 continuously enters the chilled air chamber 301 through the air duct 14. The air cooler 13 (model CBE-23AF) creates a cold air circulation. The gas then enters the housing 1 through the air duct 2, undergoing initial condensation in the chilled air chamber 301. The chilled water circulator 11 continuously circulates the chilled water in the chilled water chamber 601. The cold water circulating machine 11, model HSD-3W, condenses the gas in the gas guide pipe 2 located in the cold water chamber 601 when the gas enters the gas guide pipe 2, turning the gas into a liquid. The liquid then flows into the recovery chamber 701. Gas that has not completely formed into a liquid will enter the circulation pipe 4 under the action of the air pump 5 and re-enter the gas guide pipe 2 for condensation. This process can turn organic raw materials into liquid and recycle them through the recovery pipe 8, effectively solving the problem of organic raw material recovery. At the same time, it can accelerate the speed of bromine addition and improve production efficiency.
