Description

Technical Field

[0001] This utility model relates to the field of oil extraction and nitrogen production technology, specifically to a vibration reduction and noise reduction device for a nitrogen generator. Background Technology

[0002] A nitrogen generator is a device that uses air as raw material and employs the pressure swing adsorption principle at room temperature to separate air and produce high-purity nitrogen. Nitrogen generators are needed in the oil extraction process because nitrogen gas needs to be injected around the wellbore for insulation when hot water or steam is injected during oil extraction.

[0003] Existing nitrogen generator adsorption towers are typically fixed directly to a support frame composed of I-beams at the bottom using bolts or welding. Since the maximum pressure during on-site construction and operation can reach 35 MPa, the release of high-pressure gas into the atmosphere during pressure testing before startup and venting before shutdown causes significant vibration in the nitrogen generator adsorption tower, generating considerable noise. As environmental requirements at oilfield sites become increasingly stringent, noise levels have become a crucial indicator of on-site environmental compliance. Furthermore, prolonged exposure to noise can damage the eardrums of construction workers, impacting their health. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping and noise reduction device for a nitrogen generator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping and noise reduction device for a nitrogen generator, comprising an I-beam base and a nitrogen generator adsorption tower fixedly installed on the I-beam base. The I-beam base is composed of multiple longitudinally and transversely distributed I-beams connected together. The I-beam portion connected to the nitrogen generator adsorption tower legs is supported by a counterweight vibration damping mechanism on one or both sides. The counterweight vibration damping mechanism includes a horizontally arranged scissor bracket. Supports are hinged at the two intersection points of the scissor bracket. Carbon steel vibration damping blocks are installed on the supports. The height of the carbon steel vibration damping blocks is less than the height of the steel channel of the I-beam. An adjusting screw for adjusting the distance between the two supports is also rotatably connected to the scissor bracket.

[0006] Optionally, a slide block is fixedly connected to the support, the slide block is distributed in a vertical direction, and a vertically distributed sliding groove is opened on the back of the carbon steel damping block, the carbon steel damping block is slidably connected to the slide block through the sliding groove.

[0007] Optionally, the carbon steel shock absorber block has a groove on its front side, and a rubber buffer pad is embedded in the groove.

[0008] Optionally, the groove depth of the carbon steel damping block is greater than the thickness of the slide block, and vertically distributed limiting back plates that can fasten to the back of the slide block are connected to both sides of the opening of the groove. The limiting back plates extend upward and are set higher than the slide block, and a limiting top plate that can fasten to the top of the slide block is connected to the top of the limiting back plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This invention features a counterweight damping mechanism on one or both sides of the I-beam section connected to the nitrogen generator adsorption tower support legs. The counterweight damping mechanism includes carbon steel damping blocks that are pressed and connected to the steel channel of the I-beam, thereby achieving the damping effect on the nitrogen generator adsorption tower. At the same time, the carbon steel damping blocks can also serve as counterweights to increase the weight of the I-beam base, improve the seismic resistance of the I-beam base, and achieve the noise reduction effect of the nitrogen generator.

[0015] 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.

[0016] Example: Please refer to Figure 1-3As shown, this utility model provides a vibration reduction and noise reduction device for a nitrogen generator, including an I-beam base 1 and a nitrogen generator adsorption tower 2 fixedly installed on the I-beam base 1. The I-beam base 1 is composed of multiple longitudinally and transversely distributed I-beams connected together. The I-beam section connected to the legs of the nitrogen generator adsorption tower 2 is supported by a counterweight vibration reduction mechanism 3 on one or both sides. The counterweight vibration reduction mechanism 3 includes a horizontally arranged scissor bracket 31. The two intersection points of the scissor bracket 31 are hinged to a support 33. A slide block 34 is fixedly connected to the support 33 by bolts. The slide block 34 is distributed in a vertical direction. The back of the carbon steel vibration damping block 35 is provided with a vertically distributed sliding groove 351. The carbon steel vibration damping block 35 is slidably connected to the slide block 34 through the sliding groove 351. The height of the carbon steel vibration damping block 35 is less than the height of the steel groove of the I-beam. An adjusting screw 32 for adjusting the distance between the two supports 33 is also rotatably connected to the scissor bracket 31.

[0017] In use, first adjust the adjusting screw 32 to shorten the distance between the two supports 33, so that the two carbon steel damping blocks 35 can be easily placed between the two parallel I-beams. Then adjust the adjusting screw 32 to increase the distance between the two supports 33, so that the two carbon steel damping blocks 35 are tightly pressed into the corresponding I-beam grooves. Therefore, when the nitrogen generator adsorption tower 2 vibrates during operation, its legs also vibrate. Since the I-beam part next to the legs is equipped with a counterweight damping mechanism 3, the vibration will be transmitted to the carbon steel damping blocks 35, which can reduce the vibration and corresponding noise of the nitrogen generator adsorption tower 2 during operation. At the same time, the carbon steel damping blocks 35 can also be used as counterweights to increase the weight of the I-beam base 1, improve the stability and shock resistance of the I-beam base 1, and achieve the noise reduction effect of the nitrogen generator. Since the I-beam base 1 is fixed to the ground, the steel channel is very close to the ground. If the scissor lift bracket 31 is very close to the ground, it is inconvenient to manually operate the adjusting screw 32. Since the carbon steel damping block 35 is slidably set on the slide block 34, the height of the scissor lift bracket 31 and the slide block 34 can be adjusted upwards when the height of the carbon steel damping block 35 is constant, so as to facilitate manual control of the adjusting screw 32.

[0018] Based on the above embodiment, the carbon steel damping block 35 has a groove on its front side, and a rubber buffer pad 36 is embedded in the groove. The rubber buffer pad 36 improves the stability of the block under pressure from the steel groove, and also absorbs shock. Furthermore, its contact with the steel groove is more secure, resulting in excellent shock absorption. In addition, the depth of the groove 351 of the carbon steel damping block 35 is greater than the thickness of the slide block 34. Vertically distributed limiting back plates 352, which can hold the back of the slide block 34, are connected to both sides of the opening of the groove 351. The limiting back plates 352 extend upwards and are positioned above the slide block 34. A limiting top plate 353, which can hold the top of the slide block 34, is connected to the top of the limiting back plate 352. By providing the limiting back plate 352 and the limiting top plate 353, the carbon steel damping block 35 can be effectively prevented from falling directly off the slide block 34, improving the ease of use of the device.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
