Abstract
A kind of energy saving air-suction cover in high-altitude it be made of exhaust pipe (1), impeller (2), blade (3), upper sealing plate (4), lower sealing plate (5), it generates the negative pressure value that negative pressure is multiple times than general chimney using upper air current, air-introduced machine can be greatly lowered uses the power save energy, chimney height can also be reduced and save material, import (1) is inserted into former chimney breast when old chimney is transformed.
Description
Technical field
The energy saving air-suction cover in high-altitude is to belong to Air Pollution prevention and control and field of energy-saving technology.
One, border technology is carried on the back
General the very high of exhaust chimney building is discharged fume by upper air current air-breathing, and the present invention adds an impeller to discharge fume in high-altitude
Cover can make to increase at more times than general smoke outlet negative pressure at smoke outlet by upper air current, smoke exhaust fan can be greatly lowered
Use power.
Two, structure, technological process and principle
1, structure
The energy saving air-suction cover in high-altitude it be by exhaust pipe (1), impeller (2), blade (3), upper sealing plate (4), lower sealing plate (5) group
At.
2, technological process
When the air-flow in any one direction of high-altitude blows to impeller, air-flow is made to be generated in pipe under the water conservancy diversion of blade (3)
High-speed eddy generates larger negative pressure under the influence of centrifugal force, and the gas of exhaust pipe is quickly sucked out.
3, air-suction
Air velocity is set as V in same high-altitude1, chimney top generates negative pressure under the action of air-flow, according to bernoulli
EquationDp is negative pressure value, and γ is that two proportions of gas are constant, V1For the gas velocity of chimney outlet
Degree, V0For ground gas velocity be 0, g be gravity degree of adding at this momentWhen adding impeller calotte as shown, at this moment
Negative relative difference at outer two isAt this moment V1It is the upper air current speed of front, V2Into the gas of inner tube
Flow velocity degree, since area is much smaller than outer inlet -duct area by formula Q=F in interior import2V2, Q is flow, two import Q it is equal soWork as F2V when reducing at double2It just increases exponentially, when area is reduced toShi Sudu V2=2V1At this moment negative relativeTo ground negative pressure valueWith
First formula compares explanation, when 2 times of exhaust outlet negative pressure values that cover outer diameter is internal diameter are without 4 times of calotte, when outer diameter is
At 3 times of internal diameter, total negative pressure value is the power of exhaust air-introduced machine can be greatly lowered in this way, from other one without 9 times of calotte
Angle is seen, the height of exhaust chimney can also be substantially reduced.
Four, it illustrates
Attached drawing is the energy saving air-suction cover schematic diagram in high-altitude, and 1 be in exhaust pipe figure, figure 2 be in impeller figure, figure 3 is blade in figure
Figure in figure 4 be in upper sealing plate figure, figure 5 is lower sealing plate figure.
Five, it is embodied
The energy saving air-suction cover in high-altitude is generally used for increasing the getter action of high-altitude chimney, the exhaust dust discharge in workshop, mine
Transformation does not have to exhaust fan, and air-suction cover is plugged on original chimney.
Claims (1)
1. a kind of energy saving air-suction cover in high-altitude it is characterized in that it be by exhaust pipe (1), impeller (2), blade (3), upper sealing plate (4),
Lower sealing plate (5) composition, when the air-flow in any one direction of high-altitude blows into impeller (2) one side under the water conservancy diversion of blade (3), gas
High-speed eddy is being generated into tube hub, is generating negative pressure under the influence of centrifugal force, the gas inspiration of inlet pipe is being discharged.
