Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a purification system for nitrogen making equipment and nitrogen making equipment. Background Art

[0002] Nitrogen oxides are one of the main causes of air pollution. By using nitrogen generators to produce high-purity nitrogen, the emission of nitrogen oxides in industrial processes can be reduced. Nitrogen generators can separate nitrogen from the atmosphere, thereby reducing the nitrogen oxides produced by the reaction of nitrogen with other elements. This is of great significance to improving air quality and other issues.

[0003] A nitrogen generator is a device that uses air as raw material and uses physical methods to separate oxygen and nitrogen to obtain nitrogen. According to different classification methods, it can be divided into cryogenic air separation, molecular sieve air separation and membrane air separation. The nitrogen generators used in industry can be divided into three types. At present, the most commonly used is the three-tower nitrogen generator. During the use of the nitrogen generator, the inhaled outside air is usually purified, so as to improve the purity of nitrogen production and reduce the impurity content.

[0004] Traditional purification methods mostly use filters or directly use large-scale purification equipment for purification. The former is too simple to purify only through filters, and the purification effect is still poor. The latter has a better purification effect, but the overall initial investment cost and later maintenance cost are high, it is difficult to popularize it, and the purification effect is not thorough enough.

[0005] To this end, relevant practitioners have designed a nitrogen generator purification device as shown in CN215901212U, which purifies the gas through the purification components in the filter box after spraying water to reduce dust, and cleans the filter screen in the purification component through a scraper at an appropriate time. However, it is difficult to see the condition of the purification components in the purification box from the outside of the purification box. When it comes to operators, they are prone to forget to clean the purification components or think that other operators have cleaned them and do not clean them for a long time, resulting in a weakened purification effect.

For those skilled in the art, the present invention can be fully understood without the description of these details.

[0027] Please also read Figure 1-Figure 4 , this embodiment provides a nitrogen making system of a nitrogen making device, including a fan 10, a dust reduction mechanism 20, an air guide pipe 30, and a purification mechanism 40; The dust reduction mechanism 20 includes a dust reduction box 1, a water spraying component 2, a receiving component 3 and a driving component 4; the fan 10 is arranged on the dust reduction box 1 and connected, that is, the fan 10 generates negative pressure to draw the gas to be purified into the dust reduction box 1; the water spraying component 2 is arranged in the dust reduction box 1, the receiving component 3 is arranged in the dust reduction box 1 in a manner that it can be raised and lowered, and the driving component 4 is arranged on the dust reduction box 1, and the receiving component 3 can descend and start the driving component 4 after receiving water; that is, the water sprayed by the water spraying component 2 will be received in the receiving component 3, and after receiving a certain amount, the weight of the water causes the receiving component 3 to descend and start the driving component 4, specifically, the receiving component 3 descends to rotate the driving component 4. Preferably, a bell-shaped water guide plate is provided in the dust reduction box 1.

[0028] The purification mechanism 40 includes a purification box 5, a purification component 6 and a cleaning component 7; the purification box 5 is connected to the dust reduction box 1 through the air duct 30. Specifically, the dust reduction box 1 is connected to the purification box 5 near the bottom through the air duct 30, and the gas moves upward from the bottom of the purification box 5 to achieve purification. The purification component 6 is arranged in the purification box 5. The purification component 6 includes a filter and other parts for purification, which can be selected according to the specific usage; specifically in this embodiment, the purification component 6 includes a filter, a photocatalytic plate and an ultraviolet lamp. The cleaning component 7 can be slidably penetrated in the purification box 5. The sliding of the cleaning component 7 can scrub the purification component 6, and the driving mechanism can drive the cleaning component 7 to move back and forth.

[0029] In the present application, the liquid sprayed by the water spraying part 2 is collected in the receiving part 3. After a period of time, the gravity generated by the liquid received in the receiving part 3 drives the receiving part 3 to descend, thereby causing the driving component 4 to work, and the driving component 4 drives the cleaning component 7 to reciprocate, thereby achieving the cleaning of the purification component 6. That is, the system shown in the present application will automatically trigger the cleaning of the purification component 6 after working for a certain period of time, thereby avoiding the problem of not cleaning the purification component 6 for a long time due to forgetfulness and other reasons.

[0031] That is, after the cleaning component 7 moves for a period of time, it drives the pusher 50 to gradually approach the lower connecting component 8 until it squeezes the lower connecting component 8, so that the lower connecting component 8 is extended and inserted into the receiving component 3, and the liquid in the receiving component 3 flows into the lower connecting component 8. The receiving component 3 is reset by its own elastic force and moves away from the driving component 4 without the gravity of the water, so that the driving component 4 stops working, that is, stops cleaning the purification component 6. As a result, the cleaning of the purification component 6 shown in the present system can stop spontaneously after a period of time, thereby avoiding the wear and tear that may be caused by long-term continuous cleaning. Specifically, the bottom of the receiving component 3 has an opening that can be opened and closed.

[0032] In other schemes, the receiving component 3 includes a receiving box 31, a telescopic rod 32, a support spring 33, a baffle 34 and an elastic rope 35; the support spring 33 is fixedly arranged in the dust reduction box 1 and connected to the receiving box 31, one end of the telescopic rod 32 is connected to the inner bottom surface of the dust reduction box 1, and the other end is connected to the receiving box 31; a water outlet is arranged on the inner bottom surface of the receiving box 31, and the baffle 34 is rotatably arranged in the receiving box 31 and can close the water outlet, and the baffle 34 is connected to the inner bottom surface of the receiving box 31 through an elastic rope 35. Specifically, the lifting direction of the receiving box 31 is controlled by the telescopic rod 32, and the lower connecting component 8 can be lifted to open the baffle 34 and communicate with the receiving box 31, so that water can flow into the lower connecting component 8. Preferably, the side of the lower connecting component 8 just matches the size of the water outlet.

[0033] In other schemes, the driving mechanism includes a motor 41 and a driving gear 42; the motor 41 is arranged in the dust reduction box 1, the driving gear 42 is coaxially fixed on the output shaft of the motor 41, and can drive the purification component 6 to slide back and forth, and the switch of the motor 41 is a touch switch 43 and is arranged in the dust reduction box 1. Specifically, the descent of the receiving box 31 squeezes the touch switch 43 of the motor 41, so that the motor 41 rotates, thereby driving the cleaning component 7 to slide.

[0034] In other schemes, the cleaning component 7 includes a driven shaft 71, a driven gear 72, a driving rod 73, a driven rod 74, a connecting rod 75 and a cleaning assembly 76; the driven shaft 71 is rotatably connected to the dust suppression box 1, the driven gear 72 is coaxially fixed on the driven shaft 71, and meshes with the driving gear 42; the driving rod 73 is fixed on the driven shaft 71, one end of the driven rod 74 is hinged to the driving stem, and the other end is hinged to the connecting rod 75, the connecting rod 75 is connected to the cleaning component 7, the cleaning component 7 can be slidably penetrated in the purification box 5, and the connecting assembly 9 is arranged on the connecting rod 75.

[0035] In other embodiments, the cleaning component 7 includes a cleaning rod 761 and a cleaning plate 762; the cleaning rod 761 is arranged on the connecting rod 75 and penetrates into the purification box 5, and the cleaning plate 762 is arranged on the cleaning rod 761 away from the end of the connecting rod 75. It should be understood that the cleaning rod can clean the purification component 6, such as the filter screen.

[0036] In other schemes, the lower connection assembly 8 includes a lower water tank 81, a sliding pipe 82, a cylinder 83 and a sliding connecting rod 84; the lower water tank 81 is arranged on the bottom surface of the dust reduction box 1, the sliding pipe 82 is slidably arranged in the lower water tank 81, and can be inserted into the receiving box 31; the cylinder 83 is arranged on the dust reduction box 1, and is connected to the sliding pipe 82 through the sliding connecting rod 84. Specifically, the pusher 50 can squeeze the switch of the cylinder 83, so that it drives the sliding pipe 82 to be inserted into the receiving box 31.

[0037] In other schemes, the pusher 50 is provided with a plurality of ratchets, and the connecting assembly 9 includes a driven plate 91, a driven coupling shaft 92, a pawl 93 and a torsion spring 94; the driven plate 91 is fixedly provided on the connecting rod 75, the driven coupling shaft 92 is provided on the driven plate 91, and the pawl 93 is rotatably provided on the driven coupling shaft 92 and connected to the driven plate 91 through the torsion spring 94. It should be understood that the pawl 93 can push the ratchets on the pusher 50, so that the pusher 50 slides toward the cylinder 83, and when sliding away from the cylinder 83, the pawl 93 rotates without driving the pusher 50 to slide, thereby, by controlling the length of the pusher 50 and the distance from the pusher 50 to the cylinder 83, the cleaning assembly 76 can start the cylinder 83 only after multiple reciprocating movements, so that a single cleaning is cleaner.

[0038] In other embodiments, the driving gear 42 is an incomplete gear. By setting it as an incomplete gear, the length of the pusher 50 and the stroke of each push can be calculated, so that when the pusher 50 squeezes the cylinder 83, the driving gear 42 and the driven gear 72 lose the meshing state, and the driven shaft 71 is kept stationary by its own friction force, thereby giving the pusher 50 and the cylinder 83 enough contact time to extend the sliding tube 82.

[0039] It should also be understood that a sealing gasket is provided between the cleaning connecting rod 761 and the purification box 5 .

[0040] A nitrogen making device, a nitrogen making system using any one of the above-mentioned nitrogen making devices, comprises a nitrogen making machine, and an air outlet of the nitrogen making machine is connected to the fan.
