Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 This embodiment of a protective mechanism for cleaning dust from a cloth bag includes a rectangular frame 1 and a nitrogen chamber 2 movably disposed on the inner wall of one side of the rectangular frame 1. A gas supply pipe is connected to the right side of the nitrogen chamber 2. A heat exchanger 5 is disposed on one side of the nitrogen chamber 2. One end of the gas supply pipe is connected to the heat exchanger 5. A connecting pipe is connected to the upper end of the heat exchanger 5. A steam heating box 4 is disposed above the heat exchanger 5. The steam heating box 4 is connected to one end of the connecting pipe. A connecting pipe 8 is connected to the right side of the heat exchanger 5. A one-way valve 7 is movably disposed around the connecting pipe 8. A condenser pipe 6 is connected to the lower end of the heat exchanger 5. A cyclone separator 9 is fixedly connected to one end of the connecting pipe 8 and is disposed inside the cyclone separator 9. A liquid storage tank 15 is movably disposed below the cyclone separator 9.

[0027] The methods of removing dust from the inner wall of the dust collector bag 20 by pulse vibration and mixing steam and nitrogen by the heat exchanger 5 are existing technologies, and therefore will not be described in detail in this embodiment.

[0028] Cyclone separator 9 is an MQF-100 cyclone-type steam-water separator. Nitrogen is supplied to heat exchanger 5 via nitrogen chamber 2, while steam heating box 4 supplies steam to heat exchanger 5. Heat exchanger 5 mixes the nitrogen and steam, converting the nitrogen into high-temperature nitrogen. A condenser tube 6 is connected to the lower end of heat exchanger 5, allowing water vapor in the high-temperature nitrogen to condense and flow out. The condensed high-temperature nitrogen then enters cyclone separator 9 via connecting pipe 8. The high-speed flowing high-temperature nitrogen rotates downwards around the inner wall of cyclone separator 9, separating the water vapor. The separated water vapor falls into storage tank 15, while the separated high-temperature nitrogen flows out of the cyclone separator. The air separator 9 moves upward from its bottom center. Due to the special structure of the cyclone separator 9, the high-temperature nitrogen moving downward will not affect the high-temperature nitrogen moving upward from the bottom of the cyclone separator 9. At this time, the separated high-temperature nitrogen will enter the interior of the outlet component through the connecting component. At the same time, the dust in the high-temperature nitrogen will fall into the collection device. The dust on the inner wall of the collection device can be removed by the pulse component to prevent the accumulated dust from damaging the collection device. The high-temperature nitrogen after dust removal is filtered by the filter component and finally discharged through the exhaust component. By continuously introducing high-temperature nitrogen into the outlet component, the acidic gas overflowing from the dust collection device can be prevented from corroding the outlet component and causing damage to it.

[0029] The inner side of the cyclone separator 9 is fixedly connected with a threaded strip, and the two sides of the liquid storage tank 15 are fixedly connected with connecting plates. The lower ends of the two connecting plates are fixedly connected to the inner wall of the lower end of the rectangular frame 1.

[0030] A connecting pipe 10 is connected to one side of the cyclone separator 9, and an outlet pipe 12 is fixedly connected to one side of the connecting pipe 10. The connecting pipe 10 is connected to the inside of the outlet pipe 12. An air bag 11 is installed through the upper end of the outlet pipe 12, and a pulse valve 21 is installed through the periphery of the air bag 11. The outlet pipe 12 and the pulse valve 21 are connected through each other.

[0031] By fixing threaded strips to the inner wall of the cyclone separator 9, water vapor in the high-temperature nitrogen gas introduced into the cyclone separator 9 can be separated. By fixing connecting plates to both ends of the liquid storage tank 15, the position of the liquid storage tank 15 can be fixed to prevent the liquid storage tank 15 from shaking and overflowing. By setting the cyclone separator 9 and the connecting pipe 2 10 to be connected, the high-temperature nitrogen gas separated by the cyclone separator 9 will enter the outlet pipe 12 through the connecting pipe 2 10, preventing the separated high-temperature nitrogen gas from coming into contact with air, which would cause water vapor to mix with the acidic gas overflowing from the collection device and damage the outlet pipe 12. By setting the outlet pipe 12, gas tank 11 and pulse valve 21 to be through-type, the pulse valve 21 can directly supply gas into the outlet pipe 12.

[0032] The end of the through-pipe 12 away from the pulse valve 21 is connected to a housing 13, and a dust removal mechanism is installed inside the housing 13;

[0033] The dust removal mechanism includes a filter bag 20 for storage and a blowpipe 16 for blowing.

[0034] Several blow pipes 16 are installed through the lower end of the outlet pipe 12, and several cloth bags 20 are fixedly connected to the periphery of the fixed plate 19. Both sides of the fixed plate 19 are fixedly connected to the inner wall of the shell 13.

[0035] An air outlet pipe 14 is movably provided on one side of the fixed plate 19, and a filter screen is provided inside the air outlet pipe 14. The air outlet pipe 14 and the housing 13 are connected through each other.

[0036] By setting a dust removal mechanism inside the housing 13, the dust on the inner wall of the filter bag 20 can be removed, preventing excessive dust accumulation on the inner wall of the filter bag 20 from causing damage. Several blowpipes 16 are installed through the lower end of the outlet pipe 12. When the pulse valve 21 supplies air to the outlet pipe 12, the air inside the outlet pipe 12 will blow air onto the filter bag 20 through the blowpipes 16, achieving the effect of dust removal on the inner wall of the filter bag 20. Fixing plates 19 are set around the filter bags 20 and fixed to the inner wall of the housing 13 on both sides, which can fix the position of the filter bags 20 and prevent the filter bags 20 from shaking when the blowpipes 16 blow air onto the filter bags 20, thus preventing inaccurate dust removal on the inner wall of the filter bag 20.

[0037] The working principle of the above embodiments is as follows:

[0038] During use, nitrogen and high-temperature steam are supplied to the heat exchanger 5. The heat exchanger 5 mixes the nitrogen and high-temperature steam, and the high-temperature nitrogen is then transported to the cyclone separator 9 through the connecting pipe 1 8. The cyclone separator 9 removes water vapor from the high-temperature nitrogen to prevent water vapor from combining with acidic gas overflowing from the filter bag 20 and damaging the outlet pipe 12. The high-temperature nitrogen after water vapor removal enters the outlet pipe 12 through the connecting pipe 2 10. Gas is blown into the outlet pipe 12 through the pulse valve 21, and the gas enters the filter bag 20 through the blowpipe 16 to remove dust remaining on the inner wall of the filter bag 20. The high-temperature nitrogen carries acidic gas into the outlet pipe 14, where the filter screen filters the high-temperature nitrogen before it is discharged to the outside through the outlet pipe 14.

[0039] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0040] Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.
