Definitions
- the invention relates to a device for vacuuming gaseous, static, dynamic and mechanical fluid, in particular gas or fumes discharged from a chimney or any outlet with a substantially vertical axis.
- Vacuum cleaners are already known which are turrets composed of a hollow cap, a pipe which is integral with it and which is generally placed above the chimney, and means for extracting gaseous fluid.
- these extraction means consist of one or more blades rotating around the longitudinal axis of the turret, by means of a motor, in particular an electric motor.
- the means for extracting the gaseous fluid can be constituted by blades or a centrifugal turbine equipped for example with a two-speed motor, single-phase, etc.
- Such turrets have several disadvantages.
- the first drawback is that the hat has edges with a concavity directed downwards, or inclined downwards.
- Devices comprising a fan consisting of a first upper part formed by a conical internal surface and a rounded external surface and a second lower part formed by a conical internal surface and an external surface. rounded.
- the first and second parts make it possible to extract the gaseous fluid statically.
- a propeller actuated by a motor is placed in the lower part.
- This propeller is much larger in diameter than the diameter of the fluid supply duct to be extracted.
- this duct is cut at the lower part and the fluid to be extracted spreads inside the lower part, namely between the conical internal surface and the rounded external surface.
- this propeller rotates continuously.
- the start of the extracted gas is not constant because the wind which rushes into the device can vary in speed over time.
- an object of the invention is to provide a device aspirating gaseous fluids so that the flow rate of rejected fluids is adjusted to a desired value.
- a device for vacuuming exhaust gases or fumes, of axis XX comprising primary mechanical means of fluid extraction, static secondary means of fluid extraction and control and adjustment means making it possible to to make active or passive the primary means characterized by the fact that, in combination, in the first place the static secondary means of venturi types consist of a lower element and an upper element, superimposed, coaxial, rigidly fixed to each other , at a certain distance from each other by at least one spacer, the lower element comprising a lower bottom and a lower cap, each of them having a pseudo-frustoconical shape, the upper element comprising an upper bottom of frustoconical shape and an upper conical cap, the bottom and the cap of the lower element being traversed coaxially by a duct which is integral with them and which opens into the space included in be the two elements through a gaseous fluid outlet orifice; secondly, the primary mechanical means are constituted by a centrifugal turbine driven by a motor, placed between the elements, sucking the
- the device comprises in combination primary mechanical means for extracting gaseous fluid, static secondary means for extracting gaseous fluid, control means which make it possible to switch the mechanical means from the active state to the passive state and vice versa and adjustment means acting on the mechanical means to maintain the nominal flow rate of extracted gas flow at a minimum value.
- the primary mechanical means for extracting fluid consist of a centrifugal turbine driven by a motor.
- the static secondary means consist of a superimposed lower element and an upper element, coaxial, rigidly fixed to one another, at a certain distance from each other by at least one spacer, the lower element comprising a bottom bottom and a bottom cap, each of them having a pseudo-frustoconical shape, the upper element comprising a top bottom, and a top cap, each of them having a pseudo-frustoconical shape, the bottom and the cap of the lower element being traversed coaxially by a pipe which is integral with them, which opens into space. included between the two elements by an outlet for gaseous fluids.
- the primary mechanical means for extracting fluid are active as long as the flow rate of rejected fluid has not reached the desired minimum limit value and passive when the flow rate has reached this minimum value.
- the device according to the invention therefore makes it possible to save energy which is currently becoming increasingly rare and more expensive.
- devices of the Venturi type comprising a lower element and an upper element each consisting of a cap and a bottom, make it possible to further increase the flow rate of fluid extracted by mechanical means.
- the mechanical means are inactive, which saves money.
- the gaseous fluid suction device comprises in combination a pipe 1, a circular hollow lower element 2, with which it is made integral.
- the device according to the invention consists of primary mechanical means 17 for extracting fluid, static secondary means for extracting fluid constituted by a device of the venturi type comprising a lower element 2 and an upper element 3.
- the primary means 17 consist of a centrifugal turbine 18 shown only schematically, not in itself part of the invention, within the reach of ordinary skill in the art.
- the turbine 18 is powered by a motor 19, for example two-speed, single-phase or explosion-proof, etc.
- the lower element 2 consists of a lower bottom 6 and a lower cap 7, each of them having a pseudo-conical shape of axis XX rigidly fixed to one another according to two large common bases 8 of circular outline.
- the pipe 1 coaxially crosses the bottom bottom 6 and the bottom cap 7.
- the upper element 3 consists of an upper bottom 14 and an upper cap 15, each of them having a pseudo-conical shape. These two elements are associated with each other along their large circular contour base 16. More particularly, the lower bottom 6 and the lower cap 7 have the shape of a truncated cone. The diameter of the small base of these truncated cones is substantially equal to the diameter of the pipe 1. Furthermore, the upper bottom 14 also preferably has the shape of a truncated cone. The generatrices of the cones are inclined relative to a line perpendicular to the longitudinal axis XX of the device with an angle a of between 10 and 45 °, preferably 17 and 20 °.
- the diameter of the large common bases 8 and 16 is between 2 to 3.5 times the diameter of the pipe 1, preferably 2.5.
- the difference d between the lower cap 7 and the upper bottom 14 calculated in line with the projection of the generator of the pipe 1 is between 0.35 and 0.8 times the diameter of the pipe 1, for example 0, 5.
- the spacers are joined to each other by a mesh screen, not shown, forming a cylindrical belt of axis XX.
- the centrifugal turbine 18 sucks the gaseous fluids leaving the pipe 1 in a direction parallel to the longitudinal axis XX of the device, in the direction directed towards the inside of the device (arrow F1) and rejects the gases in a direction perpendicular to the axis XX, directed towards the outside of the device (arrow F2). Furthermore, the secondary extraction means constituted by the venturi 2, 3 reject the gases in the direction of the arrow F2.
- the control means 20 consist for example of a probe or a pressure switch. They are connected to the motor 19 to which they send pulses, in particular electrical.
- the control measuring device 20 When the wind has a sufficient force, the flow of fluid leaving the device reaches the minimum desired value, and if it exceeds it, the primary extraction means 17 are then passive. The motor 19 does not work, the control measuring device 20 then sending an electric control signal to this motor.
- venturi The advantages of applying the venturi to the mechanical means 17 can be summarized as a better yield obtained by an improvement in the penetration of gaseous fluids extracted into the atmosphere, with the assurance of always obtaining a determined nominal flow rate. Therefore, with an equal engine compared to known devices, corresponding higher flow rates are obtained.
