Description

Technical Field

[0001] The present invention relates to the technical field of gas separation and purification, in particular to a gas separation and purification device. Background Art

[0002] Nitrogen produced by air compressors is widely used in industries such as electronics, food, chemicals, and healthcare. High-purity nitrogen is used in these industries for protective gases, inert atmospheres, and food preservation. Nitrogen can also be used as a refrigerant in refrigeration equipment. During the nitrogen production process, moist air is first fed into the compressor for compression. The compressed air enters a buffer tank to maintain stable supply pressure. The compressed air then passes through an air purification system, including a high-efficiency degreaser, a refrigerated dryer, and filters. These devices remove oil, moisture, and fine particles from the air, ensuring high-quality, oil-free air. The purified air then enters the PSA adsorption system, which includes process tanks, adsorption towers, pneumatic valves, and a PLC controller. The adsorption tower is filled with carbon molecular sieves. Using the principle of pressure swing adsorption, oxygen and nitrogen molecules have different adsorption rates, preferentially adsorbing oxygen while nitrogen is concentrated in the gas phase, forming the finished nitrogen.

[0003] At present, in the process of compressing air to produce nitrogen, bag dust removal equipment is mainly used to remove tiny particles in the air. Due to the long-term use of bag dust removal equipment, more dust will adhere to the surface of the bag, which will affect the air filtration effect and need to be cleaned by backflushing in time. In the existing technology, since a support frame is fixed inside the dust bag, it can support the dust bag when it comes into contact with the dust bag, thereby improving the gas circulation effect. However, when the support frame comes into contact with a part of the surface of the dust bag, a part of the area will be blocked, and the blocked area cannot filter the gas, thereby affecting the efficiency of air separation and purification.

It solves the problem mentioned in the above background technology that since a supporting skeleton is fixed inside the dust bag, it can support the dust bag when in contact with the dust bag, thereby improving the gas circulation effect, but when the supporting skeleton contacts a part of the surface of the dust bag, it will cause a part of the area to be blocked, and the blocked part of the area cannot filter the gas, thereby affecting the efficiency of air separation and purification.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this gas separation and purification device, the first air inlet provided on the separation box facilitates the delivery of compressed gas into the separation box, and the dust bag can be used to filter impurities in the gas, thereby improving the purity of the gas. The air outlet fixed on the upper ventilation seat facilitates the discharge of the purified gas. The second air inlet provided on one side of the lower ventilation seat can be used to connect with the pulse dust collector, so that the pulse airflow flows along the pipeline into the interior of the connection seat. The support frame is provided so that the rotating rod can drive the rotating frame to rotate, so that the skeleton on the rotating frame can rotate in the dust bag, and the contact position between the skeleton and the dust bag can be adjusted. The area blocked by the skeleton can be reused, which facilitates the flow of gas during filtration, thereby improving the gas filtration effect. When the pulse airflow flows into the connection seat, it can drive the baffle to rotate. When the baffle deflects, it interferes with the first interference bar fixed to one end of the rack, which facilitates the horizontal movement of the rack and automatically drives the ratchet gear to rotate in one direction. The rotating ratchet gear can achieve the purpose of driving the rotating rod, the rotating frame and the skeleton to rotate synchronously.

[0018] 2. In the gas separation and purification device, when the dust bag needs to be cleaned, the pulse dust collector continuously generates pulse airflow, and the inside of the dust bag is affected by the impact force, causing the impurities to be shaken off, thereby achieving the purpose of cleaning and dust removal of the dust bag. At the same time, the card seat fixed on the slider can be clamped on the dust bag, and the brush plate can be installed by rotating the rotating ring connected to the card seat. When the connecting plate is driven vertically by the electric push rod, the slider can be moved vertically on the vertical pole, and the card seat can move vertically up and down on the dust bag, so that the brush plate can clean the impurities on the dust bag, thereby improving the cleaning efficiency of the impurities. The flapping plates connected by rotation on both sides of the card seat can be deflected to achieve the purpose of cleaning the dust bag. The purpose of slapping is to accelerate the falling of impurities from the dust bag. The several triangular interference blocks fixed on the vertical pole can realize the purpose of intermittent and continuous interference between the several triangular interference blocks and the first interference rod when the slider moves vertically. Through the linkage of the second interference block, the first interference frame and the first interference block, the slapping plate can be automatically deflected to slap the dust bag. During the movement, the first interference frame can realize the purpose of interference with the second interference bar fixed on the first sliding bracket, prompting the first sliding bracket to drive the second rack to move horizontally, and the second rack can realize the purpose of driving the arc-shaped tooth block, the rotating ring and the brush plate to rotate synchronously, which can greatly improve the effect of the brush plate in removing impurities attached to the dust bag.

[0019] 3. The gas separation and purification device can achieve the purpose of elastic connection between the skeleton and the rotating frame through the cooperation of the slide groove, the slide rod, the fifth spring and the guide block. The purpose of interference with the skeleton can be achieved through the hollow conical block provided on the upper ventilation seat, so that the skeleton is fitted on the inner wall of the dust bag when the dust bag is working, thereby playing a supporting role. When the second interference rod elastically connected to the upper ventilation seat is released from interference with the slider, the interference block can be subjected to the action of elastic force to move horizontally on the second sliding bracket, so that the movement of the interference block is released from interference with the hollow conical block, so that the hollow conical block is automatically moved upward by the elastic force, thereby releasing the interference with the skeleton, and causing the skeleton to automatically move closer to the middle position of the rotating frame, so that the dust bag and the skeleton can be separated by a certain distance, thereby improving the effect of the flapping plate on the dust bag.

[0033] When purifying gas, refer to Figure 1 The compressed gas is delivered to the separation box 1 through the first air inlet 5 provided on the separation box 1. The impurities in the gas can be filtered through the dust bag 4, thereby leaving the impurities on the outer surface of the dust bag 4. The filtered gas flows into the upper vent seat 2 through the inside of the dust bag 4 and is then discharged from the air outlet 6.

One end of the resistance block 50 resists the hollow conical block 45, and the other end of the resistance block 50 resists the second resistance rod 47.

[0044] In order to further improve the beating effect of the beating plate 27, refer to Figure 2-Figure 6 When the slider 26 moves downward along the vertical rod 20, the second interference rod 47 and the slider 26 can be released from the interference.
