Description

Technical Field

[0001] The utility model belongs to the technical field of acetylene production, and particularly relates to a high-purity acetylene purification device. Background Art

[0002] Acetylene is the smallest in volume among alkyne compounds, commonly known as gaseous coal and calcium carbide gas. It is mainly used in the industrial field and is flammable. During the preparation of acetylene gas, gas impurities such as hydrogen sulfide, phosphine, and arsine will remain. Therefore, an acetylene purification device is needed to remove the impurity gases in the acetylene gas, thereby improving the purity of acetylene and the quality of acetylene production.

[0003] Existing high-purity acetylene purification devices usually use reaction towers to process acetylene gas. The acetylene gas sequentially passes through reaction towers filled with sodium hypochlorite solution and alkali solution, so that the impurity gases react with the aqueous solution to form solid particles, thereby achieving purification.

[0004] During the use of existing high-purity acetylene purification devices, the concentration of the solution in the reaction tower will decrease due to the reaction, which affects the reaction efficiency with the impurity gases and thus affects the quality of subsequent acetylene purification. Summary of the Utility Model

[0005] The utility model provides a high-purity acetylene purification device, aiming to solve the problem that during the use of existing high-purity acetylene purification devices, the concentration of the solution in the reaction tower will decrease due to the reaction, which affects the reaction efficiency with the impurity gases and thus affects the quality of subsequent acetylene purification.

[0021] Please refer to Figures 1-4, Embodiments provided by the present utility model: A high-purity acetylene purification device, comprising a mounting frame 1, a reaction tower assembly 2 and a storage assembly 3. The reaction tower assembly 2 includes two tower bodies 201 fixedly arranged at the bottom inside the mounting frame 1. At the top of each of the two tower bodies 201, an air outlet pipe 202 is inserted, used to discharge the purified acetylene gas inside the tower body 201. In the middle of the bottom of each of the two tower bodies 201, a liquid discharge pipe 204 is inserted, and valves are installed at the bottom ends of the liquid discharge pipes 204. Opening the valves can discharge the reaction solution inside the tower body 201. Four support legs 208 are fixedly arranged at the bottom ends of the tower bodies 201 respectively. The support legs 208 are all L-shaped, improving the stability of the support at the bottom end of the tower body 201. An air inlet pipe 203 is inserted into the side wall of each tower body 201, facilitating the entry of acetylene gas into the tower body 201 for purification reaction. The top end of the air outlet pipe 202 is inserted into a second pipe 6, and the other end of the second pipe 6 is inserted into the end of the air inlet pipe 203, realizing the connection of the two tower bodies 201, facilitating the further reaction and purification of acetylene gas. Finally, the purified gas is discharged from the air outlet pipe 202 at the end to complete collection. A communication pipe 205 is inserted into the side wall of the tower body 201, and the communication pipes 205 are all connected to the tower body 201 for pipe connection. The storage assembly 3 includes a box body 301 fixedly arranged at the top of the mounting frame 1. Solenoid valves 302 are installed on the side walls of the box body 301 respectively. A first notch 304 is opened inside the box body 301, and a second notch 305 is opened inside the box body 301 near the first notch 304. Sodium hypochlorite and alkaline solution are filled in the second notch 305 and the first notch 304 in sequence. The box body 301 is made of fiberglass, resistant to acid and alkali corrosion. The two solenoid valves 302 are sequentially connected to the first notch 304 and the second notch 305. The ends of the solenoid valves 302 are inserted into a first pipe 4 respectively, and the other ends of the first pipes 4 are sequentially inserted into the ends of the communication pipes 205, thus realizing the connection of the tower body 201 with the second notch 305 and the first notch 304. When the solution concentration inside the tower body 201 decreases and affects the purification efficiency, the operator first opens the liquid discharge pipe 204 to discharge part of the solution, and then starts the solenoid valve 302 to make the second notch 305 and the first notch 304 be connected to the tower body 201 in sequence, thereby realizing solution replenishment, so as to keep the solution concentration stable and improve the quality of acetylene purification.

[0022] Hoops 5 are fixedly arranged on the inner side walls of the mounting frame 1 close to the tower body 201. The hoops 5 are all circular rings sleeved on the outer surface of the tower body 201. The internal dimensions of the hoops 5 are all adapted to the external dimensions of the tower body 201, improving the stability of the installation of the tower body 201.

[0023] On the side walls of the two tower bodies 201 near the lower part of the connecting pipe 205, composite ion electrodes 207 are inserted. The composite ion electrodes 207 penetrate through the side walls of the tower bodies 201 and are inserted into the interiors of the tower bodies 201. The model of the composite ion electrodes 207 is MIK-PH-5011 for detecting the solution concentration. On the side walls of the two tower bodies 201 away from the air inlet pipe 203, liquid level gauges 206 are installed. The liquid level gauges 206 are all connected to the interiors of the tower bodies 201 to observe the height of the solution inside the tower bodies 201, facilitating the monitoring of the solution concentration inside the tower bodies 201, thereby improving the accuracy of solution addition.

[0024] At the top of the box body 301 near the notch one 304 and the notch two 305, ports 303 are opened. The ports 303 are sequentially connected to the notch one 304 and the notch two 305.

[0025] Working principle: When this high-purity acetylene purification device is in use, the operator first connects an external power supply. One end of the air inlet pipe 203 is connected to the output pipeline of the acetylene generator. The acetylene generator is a device for producing acetylene gas. The produced acetylene is first transported through the pipeline and the air inlet pipe 203 to the interior of the tower body 201, where it reacts with the sodium hypochlorite solution first, and then is transported from the air outlet pipe 202 and the pipeline two 6 to the interior of another tower body 201 to react with the alkali solution, thereby improving the purity of the acetylene gas. Opening the drain pipe 204 can discharge the waste solution inside the tower body 201. The purified acetylene gas is discharged from the air outlet pipe 202 at the end to complete the collection. When the solution concentration inside the tower body 201 decreases, the operator sequentially activates the solenoid valve 302 to connect the notch two 305 and the notch one 304 to the tower body 201 in sequence, thereby realizing solution replenishment, maintaining the solution concentration stable, and improving the quality of acetylene purification.

[0026] Secondly, by observing the liquid level gauge 206, the volume of the solution inside the tower body 201 can be accurately detected, and by observing the composite ion electrode 207, the concentration of the solution inside the tower body 201 can be detected, thereby facilitating the operator to accurately detect and control the solution concentration.
