The design of the air duct for industrial vacuum equipment includes the steps of calculating the vacuum equipment, calculating the length and size of the air duct, calculating the air volume, and selecting the fan:
1: The industrial vacuum equipment confirms the steps of calculating the wind speed in the air duct based on factors such as industrial dust and properties, dust concentration, particle size, and dust concentration. 值大 10 ％ -20 ％ 就可以了，一般带有粉尘的气体配用比较大的风速通过风管内。 With reference to the minimum wind speed of the air duct city, it is sufficient to be 10 % -20 % greater than the minimum wind speed value . Generally, the gas with dust is passed through the air duct with a relatively large wind speed.
2: When filtering toxic exhaust gas, the entire filtration system must be designed in the form of negative pressure. If the exhaust gas is corrosive, the material of the air duct must be anti-corrosive material.
3: To determine the wind speed in the air duct, it is necessary to determine the wind speed according to the nature of the gas in the air duct.
4: Determine the structure within the entire duct. The structure of the air duct must be determined according to the wind speed and the material of the air duct. If it is flammable or explosive dust gas, it is necessary to add a fireproof baffle to prevent accidental occurrence. 之间 。 When carbon steel is used to make the air duct, the thickness of the air duct is generally between 1MM-5MM .
吸尘设备 在计算风管的直管地方压力后。 5: The industrial vacuum equipment calculates the pressure of the straight pipe of the air pipe. After determining the route of the air duct, the pressure loss in the straight pipe area is calculated according to the wind speed, air volume, and the diameter and pressure of the air duct.
算 出弯头接管、支线的风量损失。 6: Calculate the air volume loss of the elbow takeover and branch line. Calculate the pressure loss of the elbow takeover and branch line branch pipe according to the pressure relation table of wind speed and speed per meter.
计算 出工业吸尘设备全部风管除尘系统的压力损失。 7: Calculate the pressure loss of all air duct dust removal systems of industrial vacuum equipment.
计算 除尘设备 风道内的流量来计算。 8: Calculate the flow in the air duct of the dust removal equipment .
9: Industrial vacuum cleaners have different situations in the calculation of gas flow, the standard use status and temperature of the equipment, and normal pressure.
