Description

Technical Field

[0001] This utility model belongs to the technical field of mixed gas treatment equipment, specifically relating to an absorption and separation device for corrosive mixed gases. Background Technology

[0002] In industries such as chemical and metallurgy, mixed gases containing corrosive components such as hydrofluoric acid (HF) are often generated. These mixed gases not only pose a serious threat to the environment and human health, but also cause severe corrosion to production equipment, leading to equipment damage, shortened service life, and significantly increased maintenance costs.

[0003] Most existing corrosive gas absorption devices employ traditional absorption towers or packed tower structures, resulting in limited absorption efficiency. Due to the highly reactive chemical properties of corrosive gases such as hydrofluoric acid (HF) and their strong affinity for common adsorbents, traditional devices struggle to achieve efficient absorption within a short timeframe. This leads to some corrosive gases remaining unabsorbed and escaping into the environment, causing pollution and safety hazards. Furthermore, the operation of existing corrosive gas absorption and separation devices is complex, requiring professional monitoring and maintenance. For example, the loading, regeneration, and replacement of the adsorbent all necessitate shutdown operations, and improper operation can easily damage the equipment.

[0004] Therefore, developing a highly efficient, durable, and easy-to-operate corrosive gas mixture absorption and separation device is of significant practical importance, addressing the problems existing in current technologies. This device should effectively improve the absorption efficiency of corrosive gases, simplify the adsorbent regeneration process, enhance the corrosion resistance of the equipment, thereby extending its service life, reducing maintenance costs, and meeting the needs of industries such as chemical and metallurgical processes for treating corrosive gas mixtures.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0019] A specific embodiment of the absorption and separation device for corrosive mixed gases of this utility model includes, in this utility model, a gas storage bag 1, an atomizing vaporizer 5, a thermal desorption chamber 7, an absorption tank, and an intelligent dual-temperature regulator 10 connected in sequence. The input end of the atomizing vaporizer 5 is connected to the gas storage bag 1, and the output end of the atomizing vaporizer 5 is connected to the thermal desorption chamber 7. A jacket 8 is fixedly installed on the outside of the thermal desorption chamber 7 and connected to the intelligent dual-temperature regulator 10. The jacket 8 has a double-layer jacket structure, and the inside of the jacket 8 is filled with... The device contains an adsorbent and a hot / cold medium. An electronic thermometer 11 is connected to the outside of the thermal desorption and analysis chamber 7. An absorption tank is connected to the output end of the thermal desorption and analysis chamber 7. In this invention, the gas storage bag 1 is used to temporarily store the gas to be treated. The atomizer 5 atomizes the gas through a venturi tube and an ultrasonic atomizer in two stages to refine the liquid components in the gas to below 50 μm. The absorption tank is used to collect the gas and the desorbed gas. The atomizer 5, the thermal desorption and analysis chamber 7, the absorption tank, and the intelligent dual-temperature regulator 10 are placed at the same horizontal position.

[0020] In one embodiment of this application, preferably, the gas storage bag 1 is connected to the second connecting pipe of the atomizer 5 via a first connecting pipe 2 and a first valve 3. In this utility model, the first valve 3 is a one-way valve, and the first connecting pipe 2 is a fluororubber hose. Therefore, the gas storage bag 1 is connected to the polytetrafluoroethylene double-ferrule one-way valve via the fluororubber hose, and the gas is stably delivered to the atomizer 5 through the polytetrafluoroethylene double-ferrule one-way valve.

[0021] In one embodiment of this application, preferably, the atomizer 5 is connected to the thermal desorption chamber 7 via a third connecting pipe 6, one end of the jacket 8 is connected to the intelligent dual-temperature regulator 10 via a medium return pipe 9, the other end of the intelligent dual-temperature regulator 10 is connected to the jacket 8 via a medium inlet pipe 20, the thermal desorption chamber 7 is connected to the electronic thermometer 11 via a fourth connecting pipe 12, the absorption tank includes a first absorption tank 13 and a second absorption tank 19, the output end of the thermal desorption chamber 7 is connected to a three-way valve 16, the first absorption tank 13 is connected to one end of the three-way valve 16 via a fifth connecting pipe 14 and a second valve 15, and the second absorption tank 19 is connected to one end of the three-way valve 16 via a sixth connecting pipe 18 and a third valve 17. In this invention, the gas pipeline is made of 316L stainless steel; the medium pipeline is a steel wire mesh reinforced composite pipe, and the 316L stainless steel pipe is fixed on the tube bundle frame, which is placed on the ground. The gas flows into the thermal desorption chamber 7 from the bottom interface and flows out to the absorption tank from the top interface. After atomization pretreatment, the gas enters the double-jacketed thermal desorption chamber 7, where it is selectively adsorbed by a special adsorbent. The unadsorbed gas enters the absorption tank for deep treatment. The intelligent dual-temperature regulator 10 enables rapid regeneration of the adsorbent, and the desorbed gas is collected by another absorption tank, forming a closed-loop cycle.

[0022] In use, the absorption and separation device for corrosive mixed gases of this invention involves transporting the gas in the gas storage bag 1 to the atomizer 5 via a pipeline. The outlet of the atomizer 5 is connected to the interior 7 of the thermal desorption chamber. The gas, after being processed by the atomizer 5, enters the thermal desorption chamber 7 in a uniform atomized state, which facilitates sufficient contact between the gas and the adsorbent inside the chamber, improving absorption efficiency. The thermal desorption chamber 7 maintains a constant temperature through an intelligent dual-temperature regulator 10, ensuring the gas is under optimal temperature conditions during the desorption process. After entering the thermal desorption chamber 7, the gas is rapidly absorbed by the adsorbent. The heat generated during absorption is promptly carried away by the jacket attached to the thermal desorption chamber 7 and the medium within the jacket, maintaining a high absorption driving force and ensuring efficient absorption. The absorbed gas then enters an absorption tank via a pipeline for further processing. The absorption tank collects any incompletely absorbed gas, ensuring thorough gas treatment. When a desorption operation is required, the intelligent dual-temperature regulator 10 controls the temperature rise of the thermal desorption chamber 7 to quickly desorb the adsorbed gas. The purified gas after desorption enters another absorption tank through a pipeline for further processing, achieving gas separation and purification. The completely desorbed gas can be reused, improving the utilization rate of gas resources and also facilitating the efficient gas absorption and separation operations of the entire system.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
