Description

Technical Field

[0001] The utility model relates to the technical field of gas adsorption and purification, in particular to a sulfuryl fluoride gas adsorption and purification device. Background Technique

[0002] Sulfuryl fluoride is an inorganic compound, which is a colorless, odorless and toxic gas under normal temperature and pressure. It is mainly used as an insecticide. Due to its strong diffusion and penetration, broad-spectrum insecticidal effect, low dosage, low residue, fast insecticidal speed, short gas dispersion time, convenient use at low temperature, no effect on germination rate and low toxicity, etc., it is more and more widely used in the prevention and control of pests in warehouses, cargo ships, containers, buildings, reservoir dams, termites, overwintering pests in gardens and boring pests in live trees. However, as a colorless, odorless and toxic gas under normal temperature and pressure, after using sulfuryl fluoride for insect fumigation on some wood in a closed environment, a gas adsorption and purification device needs to be equipped to adsorb and purify sulfuryl fluoride gas to prevent the leakage of sulfuryl fluoride gas in the closed space from polluting the environment. Operators also need to wear a full set of gas-proof clothing to ensure the safety of operators.

[0003] However, most of the existing sulfuryl fluoride gas adsorption and purification devices adopt static alkali solution adsorption and purification. It is necessary to wait until the sulfuryl fluoride gas in the closed space is purified before opening and putting in the next batch of wood to be deinsectized. The adsorption efficiency is low, wasting working time. Moreover, as the sulfuryl fluoride gas adsorbed by the alkali solution in the existing gas adsorption and purification device gradually saturates, before replacing the new alkali solution, the purification efficiency of the current alkali solution decreases, which also affects the purification effect. In order to solve the deficiencies of the existing technology, we propose a sulfuryl fluoride gas adsorption and purification device. Content of the Utility Model

[0021] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1 - 3As shown in the figure, a sulfuryl fluoride gas adsorption and purification device includes a purification device main body 1. A sealing cover 2 is abutted against the top of the purification device main body 1. A liquid injection valve 21 is connected through the top of the sealing cover 2. When purifying the gas, the staff starts the air pump 5 to extract the sulfuryl fluoride gas in the enclosed space. The air pump 5 compresses and transports the extracted sulfuryl fluoride gas to the wheel-shaped pipe 7 through the first air pipe 6. The sulfuryl fluoride gas is compressed and filled into the wheel-shaped pipe 7. The sulfuryl fluoride gas is discharged into the alkali solution in the liquid storage bucket 8 through the air outlet holes opened on the wheel-shaped pipe 7. At the same time, the driving motor 3 is started to drive the stirring blade 4 to stir and mix the alkali solution and the sulfuryl fluoride gas in the liquid storage bucket 8. After the alkali solution and the sulfuryl fluoride gas in the liquid storage bucket 8 are mixed, part of the sulfuryl fluoride gas is quickly adsorbed, improving the adsorption efficiency, enabling the sulfuryl fluoride gas in the enclosed space to be cleared faster, saving the purification time, and improving the work efficiency.

[0023] As Figure 2 and Figure 4 shown in the figure, the second air pipes 9 can be detachably installed on both symmetric sides of the liquid storage bucket 8. One end of the second air pipe 9 movably penetrates through a first fixing plate 10. A plurality of branch pipes 11 are detachably installed at one end of the second air pipe 9 penetrating through the first fixing plate 10. One end of the branch pipe 11 is connected through a liquid storage tank 12. After the alkali solution in the liquid storage bucket 8 is used for a period of time, the alkali solution in the liquid storage bucket 8 gradually becomes saturated after absorbing the sulfuryl fluoride gas, and the adsorption efficiency decreases. At this time, the air pump 5 is closed to suspend the gas transportation. Then, the handle 16 is rotated to drive the valve rod 15 to open the connecting valve 14. The used alkali solution in the liquid storage bucket 8 enters the liquid storage tank 12 through the connecting valve 14. After the liquid storage tank 12 is filled with the alkali solution, the connecting valve 14 is closed. Then, the liquid injection valve 21 is opened to inject new alkali solution into the liquid storage bucket 8. Then, the air pump 5 is opened to continue transporting the sulfuryl fluoride gas. At this time, the newly injected alkali solution in the liquid storage bucket 8 quickly adsorbs the sulfuryl fluoride gas again, maintaining the original efficiency.

[0024] When the sulfuryl fluoride gas that has not been adsorbed in time fills the cavity formed between the surface of the lye in the liquid storage barrel 8 and the sealing cover 2, due to the sealing inside the liquid storage barrel 8, the sulfuryl fluoride gas continuously transported by the first gas pipeline 6 pressurizes the sulfuryl fluoride gas in the cavity. Thus, the sulfuryl fluoride gas in the cavity is transported through the second gas pipeline 9 to the branch pipe 11 and then to the gas distribution rod 13. Then, the gas distribution rod 13 discharges the transported sulfuryl fluoride gas into the lye in the liquid storage tank 12 through the gas distribution holes opened on the gas distribution rod 13. The lye in the liquid storage tank 12 is reused. Through the cooperation of the branch pipe 11 and the gas distribution rod 13, the transported sulfuryl fluoride gas is evenly dispersed in the lye in the liquid storage tank 12, increasing the contact area between the lye in the liquid storage tank 12 and the sulfuryl fluoride gas and improving the adsorption efficiency. After the overall use for a period of time, open the drain valve 20 to discharge the lye that has adsorbed sulfuryl fluoride gas, then close the drain valve 20 and open the connection valve 14 to send the lye that has been used for a period of time in the liquid storage barrel 8 back into the liquid storage tank 12. Open the liquid injection valve 21 to inject new lye into the liquid storage barrel 8, repeat the above operations, replace the lye in sequence, use the lye in sections, make the lye adsorption more saturated, reduce waste, continuously replace the lye in the liquid storage barrel 8 without reducing the purification effect, and maintain the adsorption efficiency.

[0025] Working principle

[0026] It should be noted that the present utility model is a sulfuryl fluoride gas adsorption and purification device. When in use, first open the liquid injection valve 21, and transport the lye into the liquid storage barrel 8 through the liquid injection valve 21 until the liquid storage barrel 8 is filled with nearly half of the lye. Then close the liquid injection valve 21. Next, start the air pump 5 to extract the sulfuryl fluoride gas in the enclosed space. The air pump 5 compresses and transports the extracted sulfuryl fluoride gas through the first gas pipeline 6 into the wheel-shaped pipe 7. The sulfuryl fluoride gas is compressed and filled into the wheel-shaped pipe 7, and the sulfuryl fluoride gas is discharged into the lye in the liquid storage barrel 8 through the air outlet holes opened on the wheel-shaped pipe 7. At the same time, start the drive motor 3. The output end of the drive motor 3 rotates to drive the stirring blade 4 to stir and mix the lye and the sulfuryl fluoride gas in the liquid storage barrel 8. After the lye and the sulfuryl fluoride gas in the liquid storage barrel 8 are mixed, part of the sulfuryl fluoride gas is quickly adsorbed, achieving the purpose of accelerating the adsorption efficiency.

[0027] After the lye in the liquid storage bucket 8 has been used for a period of time, turn off the air pump 5 to suspend the gas delivery. Then rotate the handle 16, and the handle 16 drives the valve rod 15 to open the connecting valve 14. The lye in the liquid storage bucket 8 enters the liquid storage tank 12 through the connecting valve 14. After the liquid storage tank 12 is filled with lye, rotate the handle 16 to drive the valve rod 15 to close the connecting valve 14. Then open the liquid injection valve 21 to inject new lye into the liquid storage bucket 8 until the liquid storage bucket 8 is filled with almost half of the lye. Then open the air pump 5 to continue delivering sulfuryl fluoride gas. When the sulfuryl fluoride gas that has not been adsorbed in time fills the cavity formed between the surface of the lye in the liquid storage bucket 8 and the sealing cover 2, due to the seal inside the liquid storage bucket 8, the sulfuryl fluoride gas continuously delivered by the first gas pipeline 6 pressurizes the sulfuryl fluoride gas in the cavity. Thus, the sulfuryl fluoride gas in the cavity is transported through the second gas pipeline 9 to the branch pipe 11, and then through the branch pipe 11 to the gas distribution rod 13. Then the gas distribution rod 13 discharges the transported sulfuryl fluoride gas into the lye in the liquid storage tank 12 through the gas distribution holes formed on the gas distribution rod 13. After the lye in the liquid storage tank 12 has been used for a period of time, open the drain valve 20 to discharge the lye that has adsorbed sulfuryl fluoride gas. Then close the drain valve 20 and open the connecting valve 14 to send the lye that has been used for a period of time in the liquid storage bucket 8 back into the liquid storage tank 12. Open the liquid injection valve 21 to inject new lye into the liquid storage bucket 8, and repeat the above operations to replace the lye in turn, so as to achieve the purpose of maintaining the purification effect.
