Description

Technical Field

[0001] This utility model relates to the field of air compression technology, and in particular to an air intake filtration system for an air compressor. Background Technology

[0002] In steel mills and other chemical plants, both oxygen generation and compressed air systems require air compressors. The raw material for these compressors comes from the surrounding air. However, the air in steel mills often contains a large amount of dust and particulate matter. To provide clean air to the compressors, the incoming air must be filtered. However, because the air in steel mills often contains a large amount of dust and particulate matter, this also puts a heavy burden on the air filters, necessitating regular shutdowns for cleaning.

[0003] This invention aims to provide an air intake filtration system for air compressors, which seeks to reduce the burden on air filters, extend maintenance cycles, and reduce the number of shutdowns for cleaning. Utility Model Content

[0020] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0021] Figure 1 The diagram shown is a structural schematic of the air intake filtration system for an air compressor according to an embodiment of the present invention. Figure 2 As shown Figure 1 A schematic diagram of the inlet filtering module in the illustrated embodiment. Figure 3 As shown Figure 2 A schematic diagram of the filter wheel in the image.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides an air intake filtration system 100 for an air compressor, including: an air filter cartridge 5, which is used to filter the air intake of the air compressor. The air filter cartridge 5 is provided with an air intake pipe 1 and an air outlet pipe 2. The air intake pipe 1 is used to introduce air, and the air outlet pipe 2 leads to the air compressor; and an inlet filter module 7, which is located at the inlet of the air intake pipe 1. The inlet filter module 7 includes: a filter screen wheel 71, on the outer periphery of which a filter screen 711 is provided. The filter screen wheel 71 is in contact with the inlet end of the air intake pipe 1, and the filter screen wheel 71 can rotate under the drive of a power device (e.g., a motor).

[0023] Air filter cartridge 5 is the main air filtration mechanism. However, the air near steel plants often contains a large amount of dust or particulate matter. This dust or particulate matter can put a heavy burden on air filter cartridge 5, necessitating shutdown for cleaning. The cleaning method involves using backflushing gas. Therefore, air filter cartridge 5 is equipped with a backflushing gas inlet pipe 3 and a backflushing gas outlet pipe 4. During shutdown cleaning, backflushing gas is introduced to backflush and clean the air filter cartridge 5. During backflushing, the backflushing gas inlet pipe 3 and the backflushing gas outlet pipe 4 are open, while the intake pipe 1 and the exhaust pipe 2 are closed. Under normal use, the backflushing gas inlet pipe 3 and the backflushing gas outlet pipe 4 are closed, while the intake pipe 1 and the exhaust pipe 2 are open.

[0024] To reduce the burden on the air filter cartridge 5 and decrease the frequency of shutdowns for cleaning, a filter screen is typically installed at the inlet of the air intake duct 1 to intercept some dust and particulate matter, thus reducing the load on the air filter cartridge 5. However, due to the high content of dust and particulate matter in the air, the filter screen at the inlet also needs to be replaced after a period of time. Manual replacement involves working at height, which is dangerous and requires stopping the vehicle. Therefore, this embodiment includes a filter screen rotating wheel 71. Figure 2 and Figure 3 As shown, a filter screen 711 is provided on the outer periphery of the filter wheel 71. The filter wheel 71 is in contact with the inlet end of the air intake pipe 1, so that part of the filter screen performs the filtering function, intercepting some dust and particulate matter. After a period of time, when enough dust and particulate matter have accumulated and the filter screen needs to be replaced, simply rotate the filter wheel 71 to move the other part of the filter screen, which has not accumulated as much dust and particulate matter, to the inlet end for use. To facilitate the rotation of the filter wheel 71, a rotatable support roller 72 is provided on the inlet end of the air intake pipe 1, and the filter screen of the filter wheel 71 abuts against the support roller 72. When the filter wheel 71 rotates, the support roller 72 also rotates. When all the filter screens on the filter wheel 71 are used up, the filter wheel 71 can be replaced. Therefore, the filter wheel 71 effectively reduces the number of replacements and extends the maintenance cycle.

[0025] Furthermore, to ensure adequate filtration, a secondary filter 73 is installed in the intake pipe 1 along the intake direction. During normal use, since the filter wheel 71 provides the filtration function, the secondary filter 73 plays an auxiliary filtration role. When the filter wheel 71 is replaced, the secondary filter 73 can temporarily act as a primary filter. Therefore, the filter wheel 71 can be replaced without stopping the machine. Since the filter wheel 71 is primarily responsible for filtration, the replacement cycle of the secondary filter 73 can also be quite long. When the secondary filter 73 needs to be replaced, it is convenient to do so because it is located near the inlet.

[0026] Furthermore, such as Figure 4 As shown, to achieve automatic cleaning of the filter wheel 71, a water jet pipe 74 and a blowing device 75 are provided on the side of the filter wheel 71. When the replaced filter part, which has accumulated dust and particles, is rotated to the side, the water jet pipe 74 sprays water to clean and wash away the accumulated dust and particles on the filter, while the blowing device 75 sprays blowing air to blow away the moisture and particles carrying the dust. Since the filter at the inlet end is only replaced periodically, the filter wheel 71 also rotates periodically, and the water jet pipe 74 and the blowing device 75 are only turned on periodically, so they will not have a negative impact on the air intake pipe.

[0027] Furthermore, a cooler 6 is installed in the air outlet pipe 2. The cooler 6 is a heat exchanger, and circulating water is supplied to the cooler 6 to cool the flowing air. The circulating water can be installed separately or an existing circulating water system can be used, as steel plants generally have readily available circulating water. The air compressor requires energy to compress air, and the reduced volume of cooled air reduces the compressor's energy consumption. Moreover, the reduced air volume lowers its pressure, making it easier to draw air from the filter cartridge.

[0028] The air intake filtration system for air compressors provided by this utility model intercepts most of the dust and particulate matter by setting up a filter wheel and a secondary filter, reducing the burden on the air filter; the filter can be renewed by rotating the filter wheel, extending the maintenance cycle and reducing the number of shutdowns for cleaning.
