[0024] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0025] Example: Please refer to Figures 1 to 8 : This invention proposes a steam purification device for preparing phosphorous acid and its control system, comprising: a shell 1, an auxiliary part 3, a control part 4, and a heating part 5; Two support legs 101 are symmetrically welded to the bottom end face of the shell 1. Both support legs 101 are in contact with the ground. A container 2 is installed inside the shell 1. An installation plate 105 is welded to the right end face of the shell 1. The auxiliary part 3 consists of a box 301, a snap-fit ​​protrusion 302, a cooling pipe 303, a sponge block 304, a centrifugal fan 305, and an exhaust pipe 306. The box 301 is installed on the mounting plate 105 by bolts. The control unit 4 consists of a control box 401, a microprocessor 402 and a timer 403. The control box 401 is fixedly connected to the mounting plate 105. The heating part 5 consists of a rotating shaft 501, a mounting base 502, a nozzle 503, a first gear 504, a drive motor 505, a second gear 506, and an air inlet pipe 507. The rotating shaft 501 is rotatably connected to the housing 1.

[0026] The shell 1 has a placement seat 102 welded inside; the outer wall of the container 2 has an auxiliary seat 201 welded on it. The auxiliary seat 201 is engaged with the placement seat 102. At this time, the outer wall of the container 2 does not contact the inner wall of the shell 1. During use, this can prevent the heat of the container 2 from spreading to the shell 1, which could lead to burns to the staff who touch the shell 1.

[0027] The outer wall of the shell 1 is welded with a protective seat 103. The protective seat 103 is a ring structure. The protective seat 103 is a protective structure for the shell 1 and personnel. During use, it can prevent foreign objects from directly colliding with the shell 1 and can also prevent personnel from touching the shell 1.

[0028] A cover plate 104 is fastened to the top surface of the housing 1. The cover plate 104 has a stepped structure. The outer wall of the lower half of the cover plate 104 contacts the inner wall of the housing 1. During use, it can improve the sealing performance between the housing 1 and the cover plate 104, thereby reducing the probability of heat leakage from the housing 1.

[0029] Among them, the top of the holding bucket 2 is connected to the filling pipe 202, and the holding bucket 2 is also connected to the air guide pipe 203, which is connected to the box body 301. The housing 301 contains a linear array of refrigeration pipes 303, which are connected to the refrigeration equipment. At this time, the gas supplied from the gas duct 203 can be condensed.

[0030] Among them, the top surface of the mounting plate 105 has slots 106 arranged in a linear array; Two snap-fit ​​protrusions 302 are symmetrically welded to the bottom end face of the box body 301. Both snap-fit ​​protrusions 302 are snap-fitted to the slot 106, which can improve the fixing firmness of the box body 301 after installation.

[0031] The box 301 contains a sponge block 304, which is located below the refrigeration pipe 303. The sponge block 304 is connected to the gas guide pipe 203. The sponge block 304 is a structure that slows down the flow of gas discharged from the gas guide pipe 203. During use, the gas flow slows down after entering the sponge block 304, which improves the condensation effect of the gas.

[0032] The box 301 is equipped with a centrifugal fan 305 on the top, and an exhaust pipe 306 is connected to the centrifugal fan 305. The exhaust pipe 306 is connected to the second condensation structure. During use, the centrifugal fan 305 can extract the gas that has not been condensed, and then perform subsequent condensation.

[0033] The top surface of the rotating shaft 501 is equipped with a mounting base 502, and the top surface of the mounting base 502 is equipped with nozzles 503 in a linear array. The nozzles 503 are located below the holding tank 2. The rotating shaft 501 is a hollow structure and is connected to the mounting base 502 and the nozzles 503. An air inlet pipe 507 is rotatably connected to the rotating shaft 501. The air inlet pipe 507 is connected to the rotating shaft 501. During use, when the rotating shaft 501 rotates, the nozzle 503 can achieve uniform heating of the container 2.

[0034] The first gear 504 is mounted on the rotating shaft 501; A drive motor 505 is installed at the bottom of the housing 1. A second gear 506 is installed on the rotating shaft of the drive motor 505. The second gear 506 meshes with the first gear 504. During use, when the drive motor 505 rotates, it can drive the rotating shaft 501 and the nozzle 503 to rotate, so that the container 2 can be heated evenly.

[0035] The control box 401 contains a microprocessor 402 and a timer 403, which are electrically connected. The microprocessor 402 is electrically connected to the drive motor 505 and the centrifugal fan 305; The timing parameter in the timer 403 is 10 seconds. During use, every 10 seconds, the microprocessor 402 controls the drive motor 505 and the centrifugal fan 305 to rotate for 10 seconds. After rotating for 10 seconds, the drive motor 505 and the centrifugal fan 305 rest for 10 seconds, and then the cycle repeats.

[0036] The specific usage and function of this embodiment are as follows: In use, the additives for preparing phosphorous acid are first added into the container 2 through the filling pipe 202.

After rotating for 10 seconds, the drive motor 505 and the centrifugal fan 305 rest for 10 seconds, and then this process is repeated. After heating, the additives are vaporized, and the vaporized gas enters the box 301 through the gas guide pipe 203. At this time, because the top of the holding container 2 is connected to the filling pipe 202, and the holding container 2 is also connected to the gas guide pipe 203, the gas guide pipe 203 is connected to the box 301; the box 301 is equipped with refrigeration pipes 303 in a linear array, and the refrigeration pipes 303 are connected to the refrigeration equipment. At this time, the gas distributed from the gas guide pipe 203 can be condensed; and because the box 301 is attached with a sponge block 304, the sponge block 304 is located below the refrigeration pipe 303. At the designated position, the sponge block 304 is connected to the air guide pipe 203. The sponge block 304 serves as a flow-reducing structure for the gas discharged from the air guide pipe 203. During use, the gas flow slows down after entering the sponge block 304, thus improving the gas condensation effect. Furthermore, a centrifugal fan 305 is installed on the top of the box 301, and an exhaust pipe 306 is connected to the centrifugal fan 305. The exhaust pipe 306 is connected to the second condensation structure. During use, the centrifugal fan 305 can extract the uncondensed gas for subsequent condensation. During use, a placement seat 102 is welded inside the shell 1; an auxiliary seat 201 is welded to the outer wall of the container 2, and the auxiliary seat 201 engages with the placement seat 102. In this case, the outer wall of the container 2 does not contact the inner wall of the shell 1, preventing heat from the container 2 from dissipating to the shell 1 and causing burns to personnel. Furthermore, a protective seat 103 is welded to the outer wall of the shell 1. The protective seat 103 has a ring-shaped structure, serving as a protective structure for both the shell 1 and personnel. During use, it prevents foreign objects from directly impacting the shell 1 and also prevents personnel from touching it. The housing 1; and because a cover plate 104 is fastened to the top surface of the housing 1, the cover plate 104 has a stepped structure, and the outer wall of the lower half of the cover plate 104 contacts the inner wall of the housing 1, which can improve the sealing performance between the housing 1 and the cover plate 104 during use, thus reducing the probability of heat leakage from the housing 1; because the top surface of the mounting plate 105 has slots 106 in a linear array; and two snap-fit ​​protrusions 302 are symmetrically welded to the bottom surface of the box 301, and both snap-fit ​​protrusions 302 are snap-fitted to the slots 106, which can improve the fixing firmness of the box 301 after the box 301 is installed; During the heating process, a mounting base 502 is installed on the top surface of the rotating shaft 501, and nozzles 503 are installed in a linear array on the top surface of the mounting base 502. The nozzles 503 are located below the container 2. The rotating shaft 501 is a hollow structure and is connected to the mounting base 502 and the nozzles 503.
