Bladeless flow-increasing environment-friendly fan

Abstract

The invention relates to the field of environment-friendly devices, in particular to a bladeless flow-increasing environment-friendly fan which comprises a mute pipeline with an air inlet, a booster fan and a fan main weldment. The fan total weldment comprises an outer cylinder and an inner cylinder sleeved with the outer cylinder, and the outer cylinder and the inner cylinder are welded to form a hollow part to form a closed circular ring used for storing wind energy; taper pipes are arranged at the two ends of the outer cylinder. A plurality of mixed flow nozzles are arranged on the outer edge of the inner cylinder and close to the output channel; an air outlet of the mixed flow nozzle is downwards inclined along the central axis of the inner barrel and forms a preset angle; a rear wing guide cylinder is arranged at one end, far away from the mixed flow nozzle, in the mixed flow nozzle; and one end of the mixed flow nozzle is communicated with the closed circular ring. The bladeless flow-increasing environment-friendly fan has the characteristics of low energy consumption and high flow speed, is applied to a waste gas treatment system of a factory, and can meet the waste gas transportation efficiency of the factory while reducing the operation number of high-power fans.

Description

technical field [0001] The invention relates to the field of environmental protection devices, in particular to a bladeless fan for increasing flow and environmental protection. Background technique [0002] At present, many high-power fans are used in the exhaust gas treatment system of the factory. Even if the exhaust gas is discharged intensively, the exhaust gas treatment effect is not good. The main reason is that the exhaust gas needs to be conducted from the air source to the roof for treatment and discharge, resulting in too long ventilation pipes, and the flow velocity in the pipes is affected by the length of the pipes, resulting in a certain degree of loss of wind energy; in order to make up for the above wind energy loss , the factory has no choice but to choose a high-power fan to meet the exhaust gas transportation in the pipeline. Therefore, the fan accounts for most of the energy consumption in the entire factory exhaust gas treatment system, which invisibly ...

[0002] At present, many high-power fans are used in the exhaust gas treatment system of the factory. Even if the exhaust gas is discharged intensively, the exhaust gas treatment effect is not good.

The main reason is that the exhaust gas needs to be conducted from the air source to the roof for treatment and discharge, resulting in too long ventilation pipes, and the flow velocity in the pipes is affected by the length of the pipes, resulting in a certain degree of loss of wind energy; in order to make up for the above wind energy loss , the factory has no choice but to choose a high-power fan to meet the exhaust gas transportation in the pipeline. Therefore, the fan accounts for most of the energy consumption in the entire factory exhaust gas treatment system, which invisibly increases the pressure on the factory's electricity cost, and not only affects The factory's revenue does not comply with the national energy conservation policy
