Description

Technical Field

[0001] The utility model belongs to the field of nitrogen generators, and in particular relates to an exhaust gas treatment component for a nitrogen generator. Background Art

[0002] A nitrogen generator is a device that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. According to different classification methods, namely cryogenic air separation, molecular sieve air separation and membrane air separation, the nitrogen generator is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. When using the nitrogen generator, a large amount of waste gas will be generated, so the nitrogen generator needs to be used in conjunction with a waste gas recovery device.

[0003] At the same time, most of the gas in the exhaust gas generated by the nitrogen generator during use is oxygen, and the conventional exhaust gas recovery device usually collects the exhaust gas directly when cleaning the exhaust gas, so that the recovery pipe inside the exhaust gas recovery device is easily blocked by the debris remaining in the exhaust gas. As a result, the exhaust gas recovery device needs to be frequently inspected and replaced with a filter during use, which increases the workload of the maintenance personnel. In view of this, the present utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a nitrogen generator exhaust treatment component, including a nitrogen generator body 1, a filter tank 3, a secondary treatment tank 6 and a collection tank 8, one side of the nitrogen generator body 1 is connected to the filter tank 3 through a first pipe 2, and one side of the filter tank 3 is connected to the interior of the chassis through a second pipe 4, the chassis is fixedly installed at the bottom of the secondary treatment tank 6, one side of the secondary treatment tank 6 is connected to the air inlet nozzle of the collection tank 8 through a third pipe 7, a first solenoid valve 9 is provided in the middle of the second pipe 4, the third pipe 7 and the fourth pipe, a second solenoid valve 10 and a gas concentration detector 11 are provided in the middle of the first pipe 2, and a control panel is provided at the front end of the nitrogen generator body 1;

[0025] Inside the filter tank 3, a plurality of U-shaped bars 13 for clamping the clamping plate 12 are equidistantly arranged. A让位槽for installing the filter screen 14 is opened in the middle of the clamping plate 12. The sizes of the filtering holes of the plurality of filter screens 14 gradually decrease from top to bottom. A dredging rod 15 adapted to the internal size of the filtering holes is provided below each filter screen 14. The lower end of the dredging rod 15 is fixed to the driving plate 16. The bottom of each driving plate 16 is fixed to the telescopic end of the electric push rod 17. The electric push rod 17 is fixed to the inner wall of the filter tank 3 through the installation pipe 18. A negative pressure hood 19 is provided at the rear side above each clamping plate 12. The negative pressure hood 19 is connected to the multi-way pipe 20 through a connecting pipe. A third solenoid valve 21 is provided in the middle of each connecting pipe. The bottom of the multi-way pipe 20 is connected to the first negative pressure feeding pump 22 through a main pipe penetrating the box body. The discharging end of the first negative pressure feeding pump 22 penetrates through the cover plate 25 of the dust collection box 24 through the feeding pipe 23 and is communicated with the inside of the dust removal cloth bag 26. The bag mouth of the dust removal cloth bag 26 is fixed to the pipe orifice of the feeding pipe 23 through a fixing hoop. Considering that most of the gas in the waste gas generated during the simultaneous use of the nitrogen generator is oxygen, and the usual waste gas recovery device usually directly collects the waste gas when cleaning the waste gas, the recovery pipe inside the waste gas recovery device is easily blocked by the residual debris in the waste gas on the filter screen 14. As a result, the waste gas recovery device needs to be frequently overhauled and the filter screen 14 needs to be replaced during use, increasing the workload of the maintenance personnel. The filter screen 14 of the present utility model for filtering the debris in the discharged gas will cooperate with the dredging pipe, the driving plate 16 and the electric push rod 17 to dredge the filtering holes blocking the filter screen 14, reducing the workload of the maintenance personnel and avoiding the need to frequently replace the filter screen 14 for cleaning. The telescopic end of the electric push rod 17 drives the driving plate 16 to顶升. At this time, the dredging rod 15 of the driving plate 16 pushes out the filtering hole, thereby pushing out the debris blocking the inside of the filtering hole. Then, the nitrogen generator body 1 will be stopped. Then, the debris above the filter screen 14 will be sucked into the inside of the dust removal cloth bag 26 by using the negative pressure hood 19.

[0026] Among them, the front corners of the dust collection box 24 are all rotatably connected with abutting blocks 27, and the abutting blocks 27 abut against the surface of the cover plate 25. An air outlet is penetrated through one side of the front end of the cover plate 25. By providing the abutting blocks 27, the cover plate 25 is fixed. When the cover plate 25 needs to be taken out, the cover plate 25 can be抽出after rotating the abutting blocks 27, and then the dust removal cloth bag 26 can be emptied and replaced.

[0027] Among them, a second negative pressure feeding pump 28 is provided inside the machine case. The second negative pressure feeding pump 28 is communicated with the inside of the secondary treatment tank 6 through a conduit. A liquid cavity for placing liquid is provided inside the secondary treatment tank 6. One side of the secondary treatment tank 6 is respectively communicated with a liquid replenishing valve 30 and a liquid discharging valve 5. By providing the secondary treatment tank 6, the gas filtered by the multi-layer filter screen 14 is further filtered. The extremely small particles will remain in the water, and the oxygen will enter the inside of the collection tank 8 through the pipeline.

[0028] Among them, a telescopic tube 29 is provided between the mounting tube 18 and the drive plate 16, and the telescopic tube 29 is sleeved on the outside of the telescopic end of the electric push rod 17. By setting the telescopic tube 29, the telescopic end of the electric push rod 17 is dust-proof, preventing particles in the gas from adhering to the telescopic end of the electric push rod 17 and affecting the service life of the electric push rod 17.

[0029] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention.
