[0002] The production of yellow phosphorus generates a large amount of yellow phosphorus tail gas, which has a complex composition and contains various easily crystallizing substances. If this tail gas crystallizes during storage, it will not only occupy storage space and affect the normal operation of storage equipment, but may also damage the equipment, reduce its service life, and increase the company's production costs. Therefore, how to effectively prevent the crystallization of yellow phosphorus tail gas during storage has become a key problem that the yellow phosphorus industry urgently needs to solve.

[0003] Publication (Announcement) No.: CN219550245U discloses a dual-circulation yellow phosphorus flue gas storage tank, including a gas tank and a dust removal unit; a fan for conveying yellow phosphorus flue gas is also installed on the inner top of the tank; a detachable movable plate is installed on the front side of the tank, and multiple frames are installed on the rear side wall of the movable plate. Dust filters are installed in the openings of the frames, and a support plate is installed below the rear side wall of the movable plate. Filter elements are installed in the through holes on the top surface of the support plate. However, yellow phosphorus flue gas contains various easily crystallizing substances and various impurities. Although the structure and material of the filter element can intercept and filter impurities and can be brushed cleaned, with the increase of use time, the dust falling off the surface of the filter element is not easy to collect and treat, causing secondary pollution and inconvenience in use.

[0025] Dual-circulation anti-crystallization diversion type gas storage tank inner liner, such as... Figures 1-3As shown, the system includes a gas storage liner 10 for preventing crystallization of yellow phosphorus tail gas. A dust collector 20 is connected to the outside of the gas storage liner 10. A vacuum pump 30 is installed on the top of the dust collector 20. One side of the dust collector 20 is open, and a sealed door 40 is hinged to the edge of the opening. An internal circulation outlet pipe 13 and an internal circulation inlet pipe 14, connected to the dust collector 20, are installed on the outer wall of the gas storage liner 10. The vacuum pump 30 is connected to the internal circulation inlet pipe 14 via a connecting pipe 31. The outlet end of the vacuum pump 30 is inserted into the top of the gas storage liner 10, and an air disc 32 with several through holes at the bottom is installed at the outlet end of the vacuum pump 30. A primary filter box 22 and a secondary filter box 23 are installed inside the dust collector 20 from top to bottom. The gas storage liner 10 can store yellow phosphorus tail gas, and the external dust collector 20 can purify the gas. For dust removal, the air pump 30 installed on the top of the dust collector 20 can realize the circulation and delivery of gas. The air pump 30 is connected to the internal circulation air inlet pipe 14 through the connecting pipe 31, which can draw the gas into the gas storage liner 10. The air plate 32 with several through holes at the bottom installed at the outlet end can make the gas enter the gas storage liner 10 more evenly. The internal circulation air outlet pipe 13 and the internal circulation air inlet pipe 14 installed on the outer wall of the gas storage liner 10 and connected to the dust collector 20 form a gas circulation channel. The sealed cabinet door 40 with an opening on one side and the opening edge connected by a hinge facilitates the operation of the internal filtration device. The primary filter box 22 and the secondary filter box 23 set from top to bottom in the dust collector 20 can perform multi-stage filtration of the circulating gas, effectively preventing the crystallization of yellow phosphorus tail gas and ensuring the stable operation of the gas storage cabinet.

[0026] Furthermore, an external gas outlet pipe 11 is installed at the bottom of the outer wall of the gas storage liner 10, which can conveniently draw out the yellow phosphorus tail gas stored in the gas storage liner 10 for use. An external gas inlet pipe 12 is installed at the top of the outer wall of the gas storage liner 10, which facilitates the introduction of external yellow phosphorus tail gas into the gas storage liner 10 for storage, thereby realizing the gas inlet and outlet function.

[0027] Specifically, the inner wall of the dust collector is equipped with a limiting strip 21 for fixing the primary filter box 22 and the secondary filter box 23. The top edges of the primary filter box 22 and the secondary filter box 23 are equipped with sliding strips 24 that slide in cooperation with the limiting strip 21, so that the primary filter box 22 and the secondary filter box 23 can be easily installed and disassembled, and can be cleaned or replaced regularly to ensure the filtration effect.

[0028] The dust collector 20 has a sealing rubber magnetic strip 25 at the opening edge, and a magnetic ring 42 that is magnetically connected to the sealing rubber magnetic strip 25 is provided on the inner edge of the sealed cabinet door 40. This allows the sealed cabinet door 40 to be tightly closed with the dust collector 20, effectively preventing gas leakage and ensuring the sealing of the gas circulation and filtration process inside the dust collector 20.

[0029] In addition, a transparent window 41 is provided on the sealed cabinet door 40, which allows the operator to directly observe the usage of the primary filter box 22 and the secondary filter box 23 inside the dust collector 20 without opening the sealed cabinet door 40. Internal lighting tubes 26 are embedded on the inner walls on both sides of the dust collector 20 for easy observation and operation.

[0030] Working principle of the inner liner of this dual-circulation anti-crystallization flow-guiding gas storage tank:

[0031] First, the yellow phosphorus tail gas enters the gas storage liner 10 through the external air inlet pipe 12 for storage. When gas circulation and anti-crystallization treatment is required, the suction pump 30 at the top of the dust collector 20 is started. The suction pump 30 draws air from the internal circulation inlet pipe 14 through the connecting pipe 31, causing the gas in the gas storage liner 10 to enter the dust collector 20 through the internal circulation outlet pipe 13. Inside the dust collector 20, the gas first undergoes preliminary filtration through the primary filter box 22, and then further fine filtration through the secondary filter box 23. The filtered gas is then pumped to its outlet by the suction pump 30 and evenly discharged into the top of the gas storage liner 10 through several through holes in the bottom of the air plate 32, forming a gas circulation.

[0032] During use, the condition of the filter box inside the dust collector 20 can be observed through the transparent window 41 on the sealed cabinet door 40. If the internal lighting is insufficient, the internal lighting tubes 26 on both sides of the inner wall of the dust collector 20 can be turned on for auxiliary observation. When it is necessary to clean or replace the filter box, open the magnetically connected sealed cabinet door 40, and use the sliding cooperation between the slide bar 24 and the limit bar 21 to remove the primary filter box 22 and the secondary filter box 23. The stored gas can be led out for use through the external gas outlet pipe 11.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
