DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] See attached Figure 1-4 The present embodiment discloses a factory toxic gas diffusion prevention emergency purification treatment device, comprising a fixed frame 1, a gas collecting hood 2, a treatment box 3, a gas storage bottle 4, a pump body and an electric three-way valve 5. The fixed frame 1 is arranged on a movable vehicle body 6, and is used to transport the emergency treatment device to the toxic gas leakage site. The gas collecting hood 2 is arranged at the front end of the fixed frame 1, the gas storage bottle 4 is arranged at the lower layer of the fixed frame 1, and the treatment box 3 is arranged at the upper layer of the fixed frame 1. One end of the pump body is connected with the gas collecting hood 2, and the other end of the pump body is connected with the gas storage bottle 4 and the treatment box 3 respectively through the electric three-way valve 5; the gas collecting hood 2 is used to collect toxic gases to prevent them from spreading. Generally, the toxic gases collected by the gas collecting hood are directly treated through the treatment box 3. When the toxic gases leak too fast, the electric three-way valve 5 cooperates with the pump body to store the toxic gases in the gas storage bottle 4 to further prevent them from spreading.

[0027] As key components of the present invention, a filter chamber 7, a photolysis chamber 8 and a disinfection chamber 9 are sequentially connected in the processing box 3. An air inlet pipe 10 is arranged on the filter chamber 7, and the air inlet pipe 10 is connected to the electric three-way valve 5. An exhaust pipe 11 is arranged at the tail end of the disinfection chamber 9.

[0028] Specifically, a sealing cover 12 is provided at the top of the filter chamber 7, and a sealing strip is provided on the inner side of the sealing cover 12 to achieve the sealing of the filter chamber 7. A filter column 13 and a dust collecting mechanism 15 are provided in the filter chamber 7, and the filter column 13 and the dust collecting mechanism 15 can be taken out by opening the sealing cover 12. More specifically, the filter column 13 is provided in the middle of the filter chamber 7, the interior of the filter column 13 is filled with activated carbon, the lower part of the filter column 13 is provided with a shaft shoulder 14, the bottom end of the filter column 13 is provided with an external thread, and the filter column 13 is threadedly connected with the filter chamber 7.

[0029] The dust collecting mechanism 15 is arranged around the filter column 13. Furthermore, the outer layer of the dust collecting mechanism 15 is in contact with the inner wall of the filter chamber 7. The inner layer of the dust collecting mechanism 15 is provided with a bracket 16, a folded filter cloth 17, an annular plate 18 and a bellows 19 from top to bottom. The bracket 16 is arranged at the top of the dust collecting mechanism 15. The bracket 16 is a hollow structure. When the bracket 16 is in contact with the sealing cover 12, the gas can enter the dust collecting mechanism 15 through the bracket 16. The top end of the folded filter cloth 17 is fixed on the bracket 16. The folds of the folded filter cloth 17 are stepped and have a certain anti-deformation ability. The folded filter cloth 17 is sealed and connected with the bellows 19 to form a sealed inner layer of the dust collecting mechanism 15. The annular plate 18 is arranged at the junction of the folded filter cloth 17 and the bellows 19. The annular plate 18 is slidably limited in the filter column 13 and is located below the shaft shoulder 14. Toxic gas enters from the hollow bracket 16 of the dust collecting mechanism 15. The filter cloth is folded in a stepped manner, which increases the surface area of ​​the inner filter layer and accelerates the circulation of toxic gas, so that the toxic gas can quickly enter the filter column 13 for primary adsorption and purification. Through the dust collecting mechanism 15, particulate impurities in the toxic gas can be filtered and collected to avoid clogging the filter column 13.

[0030] As a preferred embodiment of the present invention, a vibration mechanism is also provided at the bottom of the filter chamber 7, and the vibration mechanism is arranged inside the bellows 19. The vibration mechanism includes a spring 20, a drive motor 27 and an eccentric wheel 28. The spring 20 is slidably sleeved in the filter column 13, and the bottom end of the spring 20 abuts against the filter chamber 7, and the top end of the spring 20 abuts against the annular plate 18. The drive motor 27 and the eccentric wheel 28 are arranged beside the filter column 13, and the eccentric wheel 28 is arranged on the output shaft of the drive motor 27, and the eccentric wheel 28 abuts against the annular plate 18. Through the vibration mechanism, the folded filter cloth 17 can be driven to vibrate, and the dust at the folds of the filter cloth can be made to fall into the dust collecting mechanism without affecting the density, so as to avoid the accumulation of impurities at the filter cloth and affect the gas circulation.

[0031] The filter chamber 7 of the present invention adopts a split structural design, which not only ensures the filtration of toxic gases, but also can open the sealing cover 12 when not in use, and directly unscrew the filter column 13 to take it out. After the filter column 13 is taken out, the dust collection mechanism 15 can be taken out subsequently, which is convenient for cleaning the filter chamber 7 and avoids the direct accumulation of foreign particles in the filter chamber 7, which corrodes the filter chamber 7 and is difficult to clean.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that this embodiment further discloses the structures of the photolysis chamber 8 and the disinfection chamber 9 .

In this embodiment, the filter mechanism includes a frame 22 and a titanium dioxide ceramic filter screen 23, and the titanium dioxide ceramic filter screen 23 is arranged in the frame 22.

[0035] In this embodiment, the staggered titanium dioxide ceramic filter screens 23 form a flow channel for the gas to move forward in a curved manner, which not only extends the flow distance of the gas in the photolysis chamber 8, so that the gas can fully receive ultraviolet light for sterilization, but also can cooperate with the titanium dioxide ceramic filter screens 23 to perform photocatalysis under the irradiation of ultraviolet rays, decompose formaldehyde, TVOC, etc., effectively remove the odor in the toxic gas, and facilitate removal and cleaning.

[0036] As a preferred embodiment of the present invention, a circulation pipe 24, an atomizing nozzle 25 and a circulation pump body 26 are provided inside the disinfection chamber 9. The circulation pump body 26 is arranged at the bottom end of the disinfection chamber 9, and the atomizing nozzle 25 is arranged in the disinfection chamber 9. The circulation pipe 24 is arranged on the inner wall of the disinfection chamber 9 and is respectively connected with the circulation pump body 26 and the atomizing nozzle 25. After the disinfectant is sprayed by the atomizing nozzle, it can be fully mixed with the toxic gas to complete the final purification of the toxic gas, and the purified gas is discharged through the exhaust pipe 11.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
