The sound-proof cabin of the natural gas compressor comprises a cabin body, a first air inlet silencer, a second air inlet silencer and an air exhaust silencer. The structure and operation of the aforementioned components will be described in detail below with reference to fig. 1 to 5.
As shown in fig. 1, fig. 1 is a schematic view of an isometric view of a soundproof compartment for a natural gas compressor, which includes a cabin body in the above description, and in particular, the first intake silencer 310, the second intake silencer 320, and the exhaust silencer 110 may be disposed in the cabin body. In an embodiment, the first intake silencer 310 and the second intake silencer 320 are disposed corresponding to the first intake vent and the second intake vent, respectively. That is, the first air inlet and the second air inlet are disposed on the cabin, and the first air inlet muffler 310 and the second air inlet muffler 320 are disposed at the outer sides of the first air inlet and the second air inlet, respectively, so that the air entering the cabin through the first air inlet and the second air inlet is muffled by the first air inlet muffler 310 and the second air inlet muffler 320, respectively. In addition, in the embodiment, the first air inlet and the second air inlet are both provided with an air guide wheel 350 in the cabin body, which is more beneficial to obtaining the air flow organization for improving the heat dissipation efficiency.
Similarly, the exhaust silencer 110 is disposed corresponding to the exhaust outlet, the exhaust outlet is opened in the cabin body, and the gas in the cabin body is silenced by the exhaust silencer 110 when being exhausted through the exhaust outlet. In an embodiment, the air outlet is arranged above the cabin. This is because, the compressor is arranged in the cabin body, the compressor can generate heat when in work, the air in the cabin body is heated by the compressor and then can show a rising trend, and the air outlet is arranged above the cabin body, which is beneficial to discharge hot air flow.
Further, the cabin is formed in a rectangular parallelepiped shape, and the air outlet is provided in the ceiling wall 100 of the cabin. Referring to fig. 1, in the example given in fig. 1, the exhaust outlet may be provided near the right-side broad side of the top wall 100. On this basis, the sides of the cabin comprise two first side walls 200 arranged opposite to each other and two second side walls 300 arranged opposite to each other. Wherein, the first intake silencer 310 and the second intake silencer 320 are disposed on a second sidewall 300.
On the basis of the above-described features, the nacelle body is further provided with a first air inlet tunnel 210, a second air inlet tunnel 330 and a third air inlet tunnel 340. As will be described in further detail below in conjunction with fig. 1-5.
Before describing the arrangement positions of the first air inlet 210, the second air inlet 330 and the third air inlet 340, the sizes of the three will be described first, and for convenience of description, the three will be referred to as air inlet structures hereinafter. In an embodiment, the areas of the first air inlet and the second air inlet may be the same, and the area of the air inlet hole structure is smaller than the area of either one of the first air inlet and the second air inlet. Therefore, the air inlet hole structure can improve the air flow organization of the air entering the cabin body from the first air inlet and the second air inlet by circulating small air flows with smaller air inlet area.
Further, the area of the air intake hole structure may be 40 to 80 square centimeters. Preferably, the air inlet duct structure may be formed as a rectangular section, for example a square section, the side length of which may be, for example, 7 cm or 8 cm, which is particularly convenient for processing, and as will be given in the following description, for example, the air inlet duct structure may be formed as a circular section. In the embodiment, the area of the air inlet hole structure plays a more critical role in improving the airflow organization, and if the area of the air inlet hole structure is smaller than 40 square centimeters, the flow of the airflow passing through the air inlet hole structure is likely to be smaller, and the airflow organization is difficult to effectively improve.
However, if the area of the air inlet tunnel structure is greater than 80 square centimeters, when a large flow of air enters the cabin body through the air inlet tunnel structure, the air flow of the air entering the cabin body through the two air inlets may be difficult to form an effective air flow structure, for example, the heat dissipation effect on the high-temperature part of the compressor is reduced; in addition, the larger wind inlet tunnel structure area also causes the excessive part of the sound insulation cabin which is not provided with sound insulation materials, and also causes the sound insulation effect of the sound insulation cabin to be reduced.
On this basis, the arrangement of the air intake hole structure will be further described below. In an embodiment, the first air inlet 210 is disposed in the first sidewall 200, and the first sidewall 200 is particularly shown in fig. 1. In an embodiment, the first wind inlet tunnel 210 may be provided with at least three, for example six. As shown in fig. 1, the six first air inlet holes 210 may be arranged in two rows, one above the other, on the first side wall 200.
With further reference to fig. 1, the upper and lower rows of first air inlet holes 210 may correspond to each other, that is, for example, in order from left to right, two first air inlet holes 210 in the same order in the upper and lower rows are vertically spaced apart from each other. Further, the distance between two adjacent first air inlet holes 210 in any row may account for 30% to 38%, for example 33% or 35%, of the horizontal dimension of the first side wall 200 (the length of the first side wall 200 in the present embodiment). As described above, the six first air intake holes 210 dispersed at a reasonable distance can sufficiently improve the airflow structure of the two air intake holes by using six small airflows, and the six first air intake holes 210 can be opened and closed according to actual conditions, which will be described below.
In an embodiment, the first wind inlet holes 210 are disadvantageously arranged too densely, for example, when the distance between two adjacent first wind inlet holes 210 in the same row occupies less than 30% of the length of the first side wall 200, the first wind inlet holes 210 belonging to the same row are arranged too densely. In this case, the three air flows entering the cabin through the three first air inlet tunnels 210 in the same row are relatively dense, which may cause a short circuit between the first air inlet tunnel 210 on the first side wall 200 close to the air outlet and the air outlet, which may cause that the first air inlet tunnel 210 ports are difficult to improve the heat dissipation effect of the soundproof cabin. However, the arrangement of the first wind inlet holes 210 is also disadvantageous in a sparse manner, for example, when the distance between two adjacent first wind inlet holes 210 in the same row occupies a length of the first side wall 200, in this case, three air flows entering the cabin through three first wind inlet holes 210 in the same row are sparse, and the effect of improving the air flow organization may be reduced.
Further, the distance in the vertical direction between the two first air inlet holes 210 corresponding to each other in the vertical direction accounts for 50% to 55%, for example 52%, of the height of the first side wall 200. Similarly, the aforementioned ratio also represents the density of the first intake tunnel 210. Within this ratio range, too, the "short-circuiting" of the gas flow is advantageously avoided and the effect of improving the gas flow pattern is achieved.
With further reference to fig. 1, the positions of the second air intake hole 330 and the third air intake hole 340 will be described in detail below. The second air inlet 330 is disposed on the second sidewall 300 where the two air inlets are located. Specifically, the second air inlet tunnel 330 may be disposed in two regions, namely, a region of the second side wall 300 located outside the first air inlet (i.e., outside the second side wall 300 in the length direction, the same applies below) and a region of the second side wall 300 located outside the second air inlet. By way of example, only the second air inlet opening 330 of the second side wall 300 in the region outside the second air inlet opening is shown in fig. 1. Similarly, the second air inlet 330 may also be provided with two rows, for example, the two rows each include two second air inlets 330. Here, the distance between two adjacent second air inlet holes 330 in the same row may be set according to the rule of the distance between two adjacent first air inlet holes 210 in the same row, and the distance between two second air inlet holes 330 corresponding to each other in the vertical direction may be set according to the rule of the distance between two first air inlet holes 210 corresponding to each other in the vertical direction, which is not described herein again.
As shown in fig. 1, the third air inlet 340 may be disposed between the first air inlet and the second air inlet, for example, two third air inlets 340 arranged along the vertical direction may be disposed, and the distance between the two third air inlets 340 may also be set according to the rule of the distance between the two first air inlets 210 corresponding to each other in the above vertical direction.
Therefore, no matter the first air inlet or the second air inlet, the two sides of the first air inlet or the second air inlet are respectively provided with the airflow entering the cabin body through the second air inlet tunnel 330 and the airflow entering the cabin body through the third air inlet tunnel 340, so that the airflow organization entering the cabin body through any one of the first air inlet and the second air inlet can be effectively improved, and the heat dissipation of the high-temperature position of the compressor is facilitated.
On the basis of the above-described features, the sound-proof cabin further includes a controller and a plurality of temperature sensors, wherein the controller is electrically connected to the first air inlet 210, the second air inlet 330 and the third air inlet 340, so as to control the opening and closing of the air inlets. It should be particularly noted that, for the six first air inlet holes 210, each air inlet hole may correspond to a temperature sensor disposed at a high-temperature position of the compressor, and the temperature sensors are configured to detect a temperature at the high-temperature position and feed a signal back to the controller. According to the temperature rise condition of the high-temperature position, the six first air inlet tunnels 210 are combined by the opening number and the opening sequence to form a corresponding improvement means of airflow organization, so that the heat dissipation effect is improved.
With particular reference to fig. 2 to 5, fig. 2 to 5 show different improvements in the flow pattern, wherein the first air inlet 210 is shown here in a circular manner, the hatched circle representing the unopened first air inlet 210. As an example, fig. 2 may be understood that the first and second upper rows and the second and third lower rows of the first air inlet 210 are sequentially turned on, and after the previous first air inlet 210 in the sequentially adjacent first air inlet 210 is turned on, the next first air inlet 210 may be turned on immediately or may be turned on at a predetermined time interval, which depends on the temperature of the high-temperature position corresponding to the next first air inlet 210.
Similarly, fig. 3 shows another air flow arrangement improvement means, and the first air inlet 210 at the lower row and the second air inlet at the upper row and the third air inlet at the upper row are opened in sequence. Fig. 4 shows still another air flow arrangement improvement means, and the first lower row and the first to third upper rows of the first air inlet holes 210 are opened in sequence. Fig. 5 shows still another air flow pattern improvement means, and the first to third lower rows and the third first upper row 210 are opened in this order.
Of course, the means for improving the airflow structure is not limited to the above examples, for example, the number of the openings of the first air inlet tunnel 210 may also be 2, 3, 5 and 6, and the above-listed examples are means for facilitating heat dissipation in actual production.
The sound-proof cabin of the natural gas compressor provided by the embodiment has the advantages that through the arrangement of the air inlet hole structure with the smaller area, the airflow organization is effectively improved, the heat dissipation efficiency is improved, and the energy consumption of the exhaust equipment is reduced.
The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all changes that can be made in the details of the description and drawings, or directly/indirectly implemented in other related technical fields, are intended to be embraced therein without departing from the spirit of the present application.
