Description

Technical Field

[0001] This invention relates to the field of gas generator set technology, and more particularly to a gas generator set with a purification component. Background Technology

[0002] Gas generator sets produce a large amount of exhaust gas during operation, containing nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter, and other harmful gases. Directly releasing this exhaust gas into the air would cause serious environmental pollution and may also adversely affect human health. Therefore, exhaust gas purification devices are needed. Currently, wet scrubbing technology is widely used. It primarily works by spraying a chemical solution to react with pollutants in the exhaust gas, thereby achieving denitrification, desulfurization, and dust removal. However, in actual operation, some of the purifying solution that participates in the reaction drips to the bottom of the purification equipment and is discharged from the system without fully participating in the reaction, resulting in waste of the solution. Summary of the Invention

[0006] A fitting housing is fixedly installed on the second liquid inlet pipe, and a third filter screen is fixedly installed inside the second liquid inlet pipe. The third filter screen is located on the side of the second filter screen away from the first filter screen. A first gap and a second gap are provided inside the fitting housing. The first gap is located between the first filter screen and the second filter screen, and the second gap is located between the second filter screen and the third filter screen.

[0026] The first filter screen 50 and the second filter screen 51 are respectively provided with a first removal device 100 and a second removal device 200 with the same structure; the first removal device 100 includes a limiting groove 60 provided on the first filter screen 50, a reciprocating limiting block 61 provided in the limiting groove 60, a square tube 62 fixedly provided on the limiting block 61, a reciprocating square rod 63 provided in the square tube 62, a first spring 64 fixedly provided between the square rod 63 and the square tube 62, a straight rod 65 fixedly provided on the inner wall of the second liquid inlet pipe 12, the straight rod 65 being fixedly connected to the square rod 63, and a second spring 66 fixedly provided between the limiting block 61 and the limiting groove 60;

[0027] A mating housing 310 is fixedly installed on the second liquid inlet pipe 12. A third filter screen 313 is fixedly installed inside the second liquid inlet pipe 12. The third filter screen 313 is located on the side of the second filter screen 51 away from the first filter screen 50.

The first gap 311 is located between the first filter screen 50 and the second filter screen 51, and the second gap 312 is located between the second filter screen 51 and the third filter screen 313.

[0028] The purification housing 2 is provided with a maintenance port 101 that communicates with the interior of the purification housing 2, and an electrically controlled sealing door 102 is provided on the maintenance port 101. The electrically controlled sealing door facilitates regular manual maintenance when equipment maintenance is required by opening the door.

[0029] The mating housing 310 is provided with a first cleaning port 400 that communicates with the first gap 311. A first sealing rubber plate 401 is provided inside the first cleaning port 400. A first pressure plate 402 is fixedly provided on the first sealing rubber plate 401. The first sealing rubber plate 401 is used to seal the first cleaning port 400.

[0030] The housing 310 is provided with a second cleaning port 403 connected by a second gap 312. A second sealing rubber plate 404 is provided inside the second cleaning port 403.

[0031] The first pressure plate 402 has first threaded holes on both sides, the second pressure plate 405 has second threaded holes on both sides, and the mating housing 310 has third threaded holes around its perimeter. The first and third threaded holes are fixedly connected by a first bolt 450 and a first nut 451, and the second and third threaded holes are fixedly connected by a second bolt 452 and a second nut. The first and second pressure plates, along with the bolt fixing mechanism, allow for easy opening of the first and second pressure plates when regular cleaning and maintenance are required, facilitating the unclogging and cleaning of the first and second filters. When the first and second filters are located in the first and second gaps respectively, the third filter can also be directly inserted into the second inlet pipe for unclogging and cleaning.

[0032] The limiting groove 60 is a trapezoidal groove, and the limiting block 61 is a trapezoidal block.

[0033] Working principle: When the exhaust gas generated by the gas generator set 1 enters the purification housing 2 through the exhaust pipe 3, the exhaust gas will first pass upward through the exhaust gas impurity filter screen 303, leaving solid particles in the exhaust gas on the filter holes at the lower end of the exhaust gas impurity filter screen 303. Then, other components in the exhaust gas will continue to move upward toward the exhaust pipe 4. At the same time, the first liquid pump 6 starts, and the liquid in the liquid tank 5 enters the spray head 8 through the first liquid pump 6 and the first liquid outlet pipe 7 and is then sprayed out to react with other harmful components in the exhaust gas in the purification housing 2, thereby achieving the effect of purifying the exhaust gas. At the same time, when the liquid is sprayed onto the exhaust gas impurity filter screen 303, it will also wash away the particles in the holes of the exhaust gas impurity filter screen 303, thus clearing the exhaust gas impurity filter screen 303.

[0034] By activating the second liquid pump 10, the liquid medicine spilled at the bottom of the purification housing 2 is collected into the liquid medicine tank 5 through the second inlet pipe 12, the second liquid pump 10, and the second outlet pipe 11, facilitating the continued use of the liquid medicine and avoiding waste. During the collection process, the liquid medicine is first filtered by a filter device. When the liquid medicine reaches the first filter screen 50, the first filter screen 50 filters out the particles in the liquid medicine, allowing the filtered liquid medicine to pass through. When the first filter screen 50 is blocked due to excessive particles remaining in the holes, the continued operation of the second liquid pump 10 will cause the first filter screen 50 to move towards the second filter screen 51 under negative pressure. The first filter screen 50 will move along the length of the square rod 63, carrying the square tube 62, overcoming the resistance of the first spring 64. When the first filter screen 50 moves to the lower side of the first gap 311, because the inner peripheral wall of the second inlet pipe 12 is no longer in contact with the outer peripheral wall of the first filter screen 50, it will be pushed upward by the reset action of the second spring 66. Entering the first gap 311, the second filter screen 51 is exposed. At this point, even after the first filter screen 50 is blocked, the liquid continues to filter particles through the second filter screen 51. The negative pressure of the second pump 10 disappears as particles are filtered through the second filter screen 51. When the second filter screen 51 becomes blocked again due to particle filtration, the negative pressure of the second pump 10 pulls the second filter screen 51 towards the third filter screen 313. When the second filter screen 51 reaches below the second gap 312, the second spring 66 pushes it upwards into the second gap 312, allowing the third filter screen 313 to continue filtering the liquid particles. This three-filter structure significantly extends the cleaning time compared to using only one filter screen in the pipeline, thus greatly extending the maintenance interval and improving equipment efficiency.

[0035] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the present invention. Furthermore, the present invention described herein may have other embodiments and can be implemented or carried out in various ways.
