Description

Technical Field

[0001] The invention belongs to the technical field of blower air gallery, and in particular relates to a complete blower air gallery system. Background Art

[0002] Excessive dust content in the blower intake air will have adverse effects on the air pump blades, mainly including:

[0003] 1) Accelerated wear: A large amount of dust will intensify the friction and wear on the blade surface and shorten the service life of the blade.

[0004] 2) Reduced efficiency: Dust accumulation on the blade surface will change the aerodynamic characteristics of the blade and reduce the working efficiency of the air pump.

[0005] 3) Balance destruction: Uneven dust deposition on the blades may cause the rotor to lose balance and cause vibration.

[0006] 4) Corrosion: Certain dust components may be corrosive and accelerate the degradation of blade materials.

[0007] 5) Blockage of air duct: In severe cases, it may cause blockage of air duct and affect air circulation.

[0008] In order to solve the above problems, an air filter device needs to be installed to filter the air intake of the blower. At present, the blower air corridor design method and air filtration method have the following main problems:

[0009] 1) The wind pressure inside the air corridor is unstable, which can easily affect the operation of the blower.

[0010] 2) The air filtration method is simple and cannot guarantee long-term normal operation, resulting in a large amount of dust and other impurities inside the air corridor, which wears the blades.

[0011] When too much dust is attached to the air filter device of the air gallery of the blower, the filtering effect will be affected, and it is difficult to ensure the cleanliness of the air entering the blower. The prior art lacks special equipment for cleaning the air filter device of the air gallery of the blower.

[0012] In addition, the treatment of contaminated sludge generated by air filter cleaning is an important issue in the field of environmental protection. Untreated discharge will directly affect water bodies, soil and the surrounding ecological environment. Summary of the invention

DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0064] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0065] like Figure 1 and Figure 2 As shown, the complete blower air gallery system of this embodiment includes a gallery device 1, a cleaning device 2 and a sewage purification device 3.

[0066] like Figure 3 and Figure 4 As shown, the corridor device 1 includes an air corridor body 11, an air inlet is arranged at one end of the air corridor body 11, a plurality of blowers 12 are connected to the side of the air corridor body 11, a plurality of variable-angle guide blades 13 are installed in the air corridor body 11, and an air purification unit 14 and a variable-section unit 15 for shielding the air purification unit 14 are arranged at the air inlet of the air corridor body 11.

[0067] The present invention also includes a control system, the rotating shaft of the variable angle guide vane 13 is connected to an angle adjustment drive device, and the angle adjustment drive device is electrically connected to the control system. High-sensitivity pressure gauges and air particle detectors are evenly arranged in the air corridor body 11, and the high-sensitivity pressure gauges and air particle detectors are arranged at the top of the dust removal grille 16, and the high-sensitivity pressure gauges and air particle detectors are electrically connected to the control system.

[0068] The existing 12-room ventilation corridor of the blower often cannot meet the wind resistance requirements of air purification and multiple air compressors working at the same time. When multiple air compressors are running at the same time, the wind resistance of the ventilation corridor will increase significantly, affecting the efficiency and life of the air compressors. At the same time, traditional fixed air purification devices are difficult to maintain optimal performance under different working conditions.

[0069] The variable angle guide vane 13 of the present invention can dynamically adjust the angle. Each variable angle guide vane 13 can be adjusted within the range of 0° to 60°, and the response time is less than 2 seconds. The airflow direction and speed are adjusted in real time according to the current operating state of the blower 12 and the required airflow distribution, thereby optimizing the airflow distribution of the entire system. The variable angle guide vane 13 is made of carbon fiber composite material. The variable angle guide vane 13 can stabilize the wind pressure inside the air corridor body 11 and ensure the efficiency and life of the air compressor.

[0070] Working principle of variable angle guide blade 13: The control system receives the parameters of pressure and particle concentration from the air corridor body 11, analyzes the obvious negative pressure area at the air inlet of the blower 12 in the corridor, calculates the optimal angle configuration of variable angle guide blade 13 according to the inlet air volume, temperature, humidity, and wind resistance of the air purification device, and drives the motor to accurately adjust the angle of each variable angle guide blade 13 according to the calculation results. The change in the angle of the blade changes the direction and speed of the airflow, thereby optimizing the airflow distribution of the entire system. The whole process continues, and the system can quickly respond to any changes in the operating status of the air compressor.

[0071] The variable cross-section unit 15 is electrically connected to the control system. The variable cross-section unit 15 cooperates with the variable angle guide vane 13 to shield part of the air purification unit 14 when the air intake is small, and the specific shielding range is uniformly controlled according to the aforementioned control system.

[0072] The air inlet of the air corridor body 11 of the present invention is provided with an air purification unit 14 and a variable cross-section unit 15 for shielding the air purification unit 14. The variable cross-section unit 15 can be freely unfolded and cooperate with the variable angle guide blade 13. When the air intake is small, part of the air purification unit 14 is shielded to reduce pollution.

[0073] like Figure 5 As shown, a dust collecting grille 16 is installed at the bottom of the air corridor body 11, and a dust collecting screw 17 is installed in the dust collecting grille 16.

[0074] The dust collecting surface 173 uses electric electrostatic adsorption to enhance the adsorption capacity. The dust collecting surface 173 uses conductive or semi-conductive materials, such as metal grids, conductive polymers or carbon nanotube composites. An electrode grid is set on the dust collecting surface 173, equipped with a high-voltage DC power supply, usually between several thousand volts and tens of thousands of volts. A voltage regulating device is added to adjust the electrostatic field strength as needed. The power rod 171 rotates counterclockwise so that part of the desorbed dust is collected at the bottom. During the maintenance stage, the electric electrostatic adsorption device can be turned off, and the power rod 171 has a built-in heating device. When the heating device is turned on, the temperature rises to 80°C, so that the heated desorbed dust is collected at the bottom.

[0075] The air purification unit 14 is provided with a multi-stage filtering structure from coarse to fine. The air purification unit 14 is composed of smaller filter units, and a single filter unit has a diameter of 20 cm, which is convenient for later replacement and maintenance. The filter unit filter layer adopts gradient filtration: multi-stage filtration is set from coarse to fine, for example, a primary filter is used to remove large particles first, and then a medium filter (electrostatic precipitator: effectively removes tiny particles).

The power device 153 on the inner shielding plate 152 drives the power screw 154 to rotate, thereby driving the fixing nut 155 on the outer shielding plate 152 to move linearly, and the outer shielding plate 152 moves with the fixing nut 155 to adjust the shielding area of ​​the air purification unit 14, and the air intake in the air corridor body 11 is adjusted.

[0079] Specifically, there are four shielding plates 152, and the area of ​​each shielding plate 152 is one-fourth of the area of ​​the air inlet of the air corridor body 11. When the four shielding plates 152 are fully unfolded, the air purification unit 14 can be completely covered.
