Description

Technical Field

[0001] The invention belongs to the technical field of blower air corridors, and in particular relates to a blower room air corridor and an air purification device. 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. Summary of the invention

[0011] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide an air corridor and air purification device for a blower room, which greatly improves the working efficiency of the blower and increases the service life of the air filtration device by stabilizing the wind pressure and multi-stage filtration.

[0014] The variable angle guide vane of the present invention can dynamically adjust the angle, and each variable angle guide vane can be adjusted within the range of 0° to 60°, with a response time of less than 2 seconds. The airflow direction and speed are adjusted in real time according to the current blower operating state and the required airflow distribution, thereby optimizing the airflow distribution of the entire system. The variable angle guide vane can stabilize the wind pressure inside the air corridor body and ensure the efficiency and life of the air compressor.

[0015] The air inlet of the air corridor body of the present invention is provided with an air purification unit and a variable cross-section unit for shielding the air purification unit.

DETAILED DESCRIPTION

[0041] 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.

[0042] 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.

[0044] The present invention also includes a control system, the rotating shaft of the variable angle guide vane 3 is connected to an angle adjustment drive device, and the angle adjustment drive device is electrically connected to the control system.

[0045] The existing 2-room ventilation corridor of the blower is often difficult to 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 compressor. At the same time, traditional fixed air purification devices are difficult to maintain optimal performance under different working conditions.

[0046] The variable angle guide blade 3 of the present invention can dynamically adjust the angle, and each variable angle guide blade 3 can be adjusted within the range of 0° to 60°, with a response time of less than 2 seconds. The airflow direction and speed are adjusted in real time according to the current operating state of the blower 2 and the required airflow distribution, thereby optimizing the airflow distribution of the entire system. The variable angle guide blade 3 is made of carbon fiber composite material. The variable angle guide blade 3 can stabilize the wind pressure inside the air corridor body 1 and ensure the efficiency and life of the air compressor.

[0047] Working principle of variable angle guide blade 3: The control system receives the parameters of pressure and particle concentration from the air corridor body 1, analyzes the obvious negative pressure area at the air inlet of the blower 2 in the corridor, calculates the optimal angle configuration of variable angle guide blade 3 according to the inlet air volume, temperature, humidity, and air purification device wind resistance, and drives the motor to accurately adjust the angle of each variable angle guide blade 3 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.

[0048] The variable cross-section unit 5 is electrically connected to the control system. The variable cross-section unit 5 cooperates with the variable angle guide vane 3 to shield part of the air purification unit 4 when the air intake is small, and the specific shielding range is uniformly controlled according to the aforementioned control system.

[0052] The dust collecting surface 73 uses electrostatic adsorption to enhance adsorption capacity. The dust collecting surface 73 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 73, equipped with a high-voltage DC power supply, usually between several thousand volts and tens of thousands of volts. A voltage regulator is added to adjust the electrostatic field strength as needed.

[0053] The power rod 71 rotates counterclockwise to collect part of the desorbed dust at the bottom. During the maintenance phase, the electric electrostatic adsorption device can be turned off, and the power rod 71 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.

[0054] The air purification unit 4 is provided with a multi-stage filtering structure from coarse to fine. The air purification unit 4 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-efficiency filter (electrostatic precipitator: effectively removes tiny particles).

[0055] like Figure 4 As shown, the air inlet of the air corridor body 1 is provided with a slide rail 8, and the air purification unit 4 is arranged in the slide rail 8. The air purification unit 4 can be moved into the cleaning device through the slide rail 8 for cleaning.

[0057] The electric rotating device 51 can drive the entire variable cross-section unit 5 to tilt as a whole, thereby controlling the opening and closing of the variable cross-section unit 5. The power device 53 on the inner shielding plate 52 drives the power screw 54 to rotate, thereby driving the fixing nut 55 on the outer shielding plate 52 to move linearly, and the outer shielding plate 52 moves with the fixing nut 55 to adjust the shielding area of ​​the air purification unit 4, and the air intake in the air corridor body 1 is adjusted.
