Definitions
- the invention relates to baffle assemblies and more particularly to such baffle assembly that employs a special airflow diversion panel or baffle to establish a negative pressure for fluid (e.g., water or gas) stream and establish water cyclones or flame cyclones to increase particulate removal capability wherein the baffle assembly is applicable to a washing tower that employs water or chemicals for washing or applicable to a burning tower.
- fluid e.g., water or gas
- baffles are used for controlling airflows. Fluid cyclones or flame cyclones are typically established by means of baffles. But a special fluid cyclone or flame cyclone has never been employed in a cyclone washing tower or a cyclone burning tower. There are a variety of traditional mechanisms used for dissolving gases. But most traditional Venturi washing mechanisms are small and primarily for household usage. The traditional washing devices not only have poor solubility but also get clogged easily. Traditional washing devices are not applicable for strong airflow environment.
- the conventional washing tower installed in a large factory utilizes a device which is adapted to sprinkle to dissolve gases and water.
- the size of the tower is required to be large. This is not desired.
- the same drawback occurs in burning tower applications. Thus, the need for improvement still exists.

Then the gas enters the tower 10 in accordance with the description described with respect to FIG. 28 to establish a single-side twin fluid cyclones within each of U-shaped baffles 22 with canted corners. With water spraying and sprinkling, a good cyclonic effect is established.
- the bottom of the washing tower has a water tank 13
- the washing tower 10 has a plurality of inverted U-shaped baffles 21 and a plurality of U-shaped baffles 22 with canted corners arranged horizontally in alternating fashion in opposing directions and offset with respect to each other and being disposed at about middle of the washing tower 10 (see FIGS. 2 and 3 ).

Since the side having an opening of each baffle is the external side of the baffle assembly facing the windward side, the cyclones established by the gas form a regular flow, and thus the opening of each baffle on the external side of the baffle assembly should be set on the wind extracting side to prevent the occurrence of turbulences.
- the baffles with their openings facing a wind extracting side are offset, embedded, opposite and coupled with each other to form a baffle assembly with their opening facing a windward side, and the linear acceleration is used to establish cyclones by the fluid current in the baffles with their openings facing the windward side.

If the burning-flame current is situated in the baffle assembly 22 , 29 , the cyclonic diversion structure comprised of a combination of baffles will conduct downward combustions, and its burning position is higher than the burning position of the cyclonic diversion structure.
- baffle 22 or the baffle 19 Due to the different burning positions, combustion and dissolution effects are produced by the fluid current turbulence and the air turbulence occurred at the diversion gap, and such diversion provides a burning effect to increase combustion efficiency.
- the internal side of the baffle 22 or the baffle 19 increases unsettled combustion. If the air for the combustion flows backward, the holdup time will increase.
- the gap situated in a plurality of baffles 22 or baffles 19 comprised of a plurality of water walls 24 (or water hollow wall panels 24 A) allows the flame to go through the gap in the baffle assembly 20 , and the gap can be used for enhancing the stability of discharging air and preventing clog from occurring.

- heat exchange is conducted at the water walls 24 (baffle space 27 ) to cool the discharged air passing through the tubes of the boiler.
- These tubes are radially connected to the top and bottom of each steam drum.
- the discharged gas will pass through an exhaust passage 12 and a chimney and leaves this unit.
- the blower 41 is forced to supply air to facilitate the airflow for the combustion and provide a static pressure to overcome the resistance caused by the exhausts of the boiler and pass the burning gas through the chimney to the outside.
- the number and the diameter of the tube of the water wall 24 as well as the shape, arrangement, separation and material of the baffles are selected according to the fluid flow and heat transfer of the industrial standard in order to achieve the required pressure drop of the water/steam and the required heat absorption from the chimney passage so as to minimize the amount of NOx produced during the burning process. This also applies to the baffles 43 , 44 , 45 , 46 , and thus these baffles will not be described herein.

- an angular of baffle change (of a corner rounding angle) greater than 90 degrees is made when the current flows through the baffle assemblies 20 so that the current establishes a plurality of double-side twin cyclones by the combustion. If the flame reaches the position of a baffle 22 or a baffle 19 , the turbulent flame is blocked to help the combustion of the burning gas so as to completely combust all hard-to-burn gas remained therein. This also applies to the baffles 43 , 44 , 45 , 46 , and thus these baffles will not be described herein.
- the diversion panel in the burning tower 9 serves as a diversion for the air and forces the gas to enter from the air inlet above through the baffle assembly 20 and perform a gas-fire melting at the baffle 21 ( 18 ) and the baffle 22 ( 19 ) so as to burn the liquid fuel or the solid fuel 26 in the primary combustion chamber 28 wherein the flame rises, and the wind blows in high speed downward to oppose each other and increase the holdup time.

Abstract
In one embodiment, a baffle assembly is mounted in a washing tower including an inlet, an outlet, a water pump, a blower, and a water tank and includes lower first baffles of U arranged horizontally or in cascade; and higher second baffles of U arranged horizontally or in cascade. The first and second baffles are further arranged in alternating fashion in opposing directions and the first baffles are offset with respect to the second baffles so that incoming water passes a gap between any two adjacent first baffles and leaves through a gap between any two adjacent second baffles by establishing twin cyclones inside space of the first and second baffles. The twin cyclones can increase holdup time of water in the tower and thus increase washing efficiency. The invention also applies to a burning tower by disposing baffle assemblies in at least of one layer fashion.

- 2. Description of Related Art
- In general, baffles are used for controlling airflows. Fluid cyclones or flame cyclones are typically established by means of baffles. But a special fluid cyclone or flame cyclone has never been employed in a cyclone washing tower or a cyclone burning tower. There are a variety of traditional mechanisms used for dissolving gases. But most traditional Venturi washing mechanisms are small and primarily for household usage. The traditional washing devices not only have poor solubility but also get clogged easily. Traditional washing devices are not applicable for strong airflow environment.
- In general, as shown in
FIG. 1 the conventional washing tower installed in a large factory utilizes a device which is adapted to sprinkle to dissolve gases and water. However, if airflow is strong the size of the tower is required to be large. This is not desired. The same drawback occurs in burning tower applications. Thus, the need for improvement still exists. - It is therefore one object of the invention to provide a baffle assembly mountable in a washing tower including an inlet, an outlet, water pumping means, blowing means, and a water tank, comprising a plurality of first baffles of U arranged horizontally; and a plurality of second baffles of U disposed higher than the first baffles and arranged horizontally, wherein the first and the second baffles are arranged in alternating fashion in opposing directions; the first baffles are offset with respect to the second baffles; incoming water is adapted to pass a first gap between any two adjacent first baffles and leave through a second gap between any two adjacent second baffles by establishing a plurality of cyclones in the first and the second baffles; a first length of the first gap is substantially equal to a second length of the second gap; a first distance between one side of the first baffle and one side of the second baffle is substantially equal to half of the first length; a second distance between the other side of the first baffle and the other side of the second baffle is substantially equal to half of the first length; a third distance between a bottom of the second baffle and a top end of the other side of the first baffle is smaller than a diameter of the cyclone but larger than a radius thereof; and a fourth distance between the bottom of the first baffle and a bottom end of one side of the second baffle is less than a diameter of the cyclone but greater than a radius thereof.
- It is another object of the invention to provide a baffle device having at least one assembly mountable in layer fashion in a burning tower including an inlet, an outlet, ignition means, and blowing means, each assembly comprising a plurality of first baffles of U arranged either horizontally or slantingly or in cascade; and a plurality of second baffles of U disposed higher than the first baffles and arranged either horizontally or slantingly or in cascade, wherein the first and the second baffles are arranged in alternating fashion in opposing directions; the first baffles are offset with respect to the second baffles; incoming air is adapted to pass a first gap between any two adjacent first baffles and leave through a second gap between any two adjacent second baffles by establishing a plurality of cyclones in the first and the second baffles; a first length of the first gap is substantially equal to a second length of the second gap; a first distance between one side of the first baffle and one side of the second baffle is substantially equal to half of the first length; a second distance between the other side of the first baffle and the other side of the second baffle is substantially equal to half of the first length; a third distance between a bottom of the second baffle and a top end of the other side of the first baffle is smaller than a diameter of the cyclone but larger than a radius thereof; and a fourth distance between the bottom of the first baffle and a bottom end of one side of the second baffle is less than a diameter of the cyclone but greater than a radius thereof.

According to the invention, the baffle shapes comprise, but not limited to, U-shaped baffles with canted corners, inverted U-shape, rising-arm-type U-shape, large-mouth-type U-shape, extending-arm-type U-shape, holding-arm-type U-shape, small-mouth-type U-shape, inverted-V-arm type U-shape, 7-type U-shape, and slanted 7-type U-shape.
- Referring to FIGS. 2 to 5, 10 and 13 together with FIGS. 6 to 9, 11, 12, 14, 15, 25, 26, 28, and 30, the invention is applied to a washing tower. A
baffle assembly 20 of the invention establishes fluid cyclones for washing. The washing tower can be a water washing tower, a chemical washing tower or a heat-resistant sealed washing tower. The sealedwashing tower 10 includes anair inlet 11 disposed on a first top of the tower, and anair outlet 12 disposed on a second top of the tower. Thewashing tower 10 includes abaffle assembly 20 having acontrol valve 30 and adiversion panel 14 in thetower 10 and at positions proximate to theair inlet 11 for adjusting the flow and establishing a linear acceleration for the gas entering thewashing tower 10 respectively. Then the gas enters thetower 10 in accordance with the description described with respect toFIG. 28 to establish a single-side twin fluid cyclones within each ofU-shaped baffles 22 with canted corners. With water spraying and sprinkling, a good cyclonic effect is established. Further, the bottom of the washing tower has awater tank 13, and thewashing tower 10 has a plurality of invertedU-shaped baffles 21 and a plurality ofU-shaped baffles 22 with canted corners arranged horizontally in alternating fashion in opposing directions and offset with respect to each other and being disposed at about middle of the washing tower 10 (seeFIGS. 2 and 3 ). The baffles are shaped differently. - Referring to FIGS. 6 to 9, 11, 12, 14 and 15, a
baffle assembly 20 are a plurality of inverted U-shaped baffles 22. Each angle of the invertedU-shaped baffle 22 is greater than 90 degrees. Thebaffle assembly 20 also can be formed as holding-two-arms type U-shaped baffles 19. Thebaffle assembly 20 is disposed transversely in the tower. When gas enters the baffles, inverted U-shaped baffles 21 facing wind extracting side to avoid interference of current.U-shaped baffles 22 with canted corners face a windward side. The baffles are arranged horizontally in alternating fashion in opposing directions and offset with respect to each other. Small-mouth typeU-shaped baffle 18 face a wind extracting side. Holding-two-arms type U-shaped baffles 19 face a windward side. The baffles are arranged horizontally in alternating fashion in opposing directions and offset with respect to each other. By configuring as above, the gas passes through inverted U-shaped baffles 22 or holding-two-arms type U-shaped baffles 19 to establish twin cyclones such that the gas or water washing process will be carried out and concentrated on the cyclonic section to guide the gas or water current so as to establish the twin cyclonic effect and improve the solubility. The polygonal baffles 21, 22, 18, 19 are installed corresponding to each other to form abaffle assembly 20 with a gap between thebaffle 21 and thebaffle 22 or a gap between thebaffle 22 and thebaffle 22, or a gap between thebaffle 18 and thebaffle 19, or a gap between onebaffle 19 and anadjacent baffle 19. The gap can be adjusted (will be described inFIG. 25 ) in accordance with the invention. Thebaffle assembly 20 is arranged transversely to form a filter layer. The external side of thebaffle assembly 20 are provided with a plurality of throttle baffles including anoblique baffle 15 and anangle iron baffle 16. The angle of theoblique baffle 15 is smaller than 90 degrees. Theoblique baffle 15 orangle iron baffle 16 is welded on thebaffle assembly 20 and situated between twobaffles 21, twobaffles 22, twobaffles 18, or twobaffles 19 so as to allow the current to pass through a gap between the external side (which is a windward side) of thebaffle assembly 20 and theoblique baffle 15 or theangle iron baffle 16. Due to the speed difference and the negative pressure, the gap can accumulate impurities having a specific gravity greater than that of the gas. The impurities will be mixed slowly with the water washing substance ofU-shaped baffles 22 with canted corners orcorners 220A and 220B ofbaffle 22 as shown inFIG. 25 . The impurities are finally removed out of thebaffles 22 through thedrainpipe 229 together with water as shown inFIGS. 33-34 . Further, the internal side of thebaffle 22 orbaffle 19 collects a large amount of water. When there is a current, the baffle assembly forms a diversion structure between a plurality of upper andlower baffles 22. Water will fall from the top into the diversion structure. Hence, the water level is higher than the water level outside the cyclonic diversion structure. With the gas-liquid dissolving effect caused by the water turbulence formed by the high and low water levels and the air turbulence formed at the diversion gap, the diversion gap has a Venturi washing effect to provide a high solubility. The baffle 231 (seeFIG. 5 ) can stabilize the fluid cyclones and the internal side of thebaffle 23 or thebaffle 19 can gather a large amount of turbulent water. When the air and water flow back, the plurality ofholes 23A disposed on the bottom ofbaffle 23 or thebaffle 23 are provided with the drains of a connectingduct 232. Theoverflow baffle 23B has an edge higher than that of a normal baffle, so that air and water can pass through the gap of thebaffle assembly 20. Theholes 23A are provided for improving discharging water and preventing possible clogs. The same applies to thebaffles - In the invention, each baffle employs one side having the
air inlet 11 as the windward side and the other side having theair outlet 12 as the wind extracting side. Since the side having an opening of each baffle is the external side of the baffle assembly facing the windward side, the cyclones established by the gas form a regular flow, and thus the opening of each baffle on the external side of the baffle assembly should be set on the wind extracting side to prevent the occurrence of turbulences. In the meantime, the baffles with their openings facing a wind extracting side are offset, embedded, opposite and coupled with each other to form a baffle assembly with their opening facing a windward side, and the linear acceleration is used to establish cyclones by the fluid current in the baffles with their openings facing the windward side. Therefore, the baffle assembly of the invention forms a multi-layer baffle assembly. The number of the baffles of the baffle assembly is not limited. Any structure having the foregoing characteristics and capable of establishing double-side or single-side twin cyclones is intended to be covered in the scope of the baffle assembly of the invention. - In
FIGS. 3, 5 , 7, 8, and 9, adiversion panel 14 in thewashing tower 10 serves as a diversion for the gas and forces the gas entering from the air inlet through thediversion panel 14 to be blocked by thebaffles baffle assembly 20, thebaffles corners 220A, 220B between thebaffle water washing tank 13. Finally, the clean air filtered by the gas-liquid solution is discharged from theair outlet 12. The same applies to thebaffles - In
FIGS. 4, 5 , 9, and 12 and 15, if the air is introduced from theair inlet 11 and blocked by the followingdiversion panel 14 before entering awater washing tank 13, a first contact will be made to collect dusts, chemical particles and other larger particles prior to entering thewater washing tank 13. InFIGS. 4 and 25 , if the fluid current passes through thebaffle assembly 20 as described inFIG. 25 , the fluid current in thebaffles baffles baffle baffle 19, the turbulent water will be blocked to assist the production of more gas-liquid dissolutions such that the gas will stay in the water. The same applies to thebaffles - In FIGS. 2 to 5, 10 and 13, the invention has a
diversion panel 14 disposed at the top of thewashing tower 10 and corresponding to the position above or below each transverse baffle assembly such that the gas entering into thewashing tower 10 can establish a linear acceleration. On the bottom of thewashing tower 10 there are provided awater washing tank 13, awater pump 30 for pumping water in thewater washing tank 13 for spraying and sprinkling water for the air and water dissolution, and theblower 40 for blowing gas upward by drawing gas from the side. The dragging force of the twin cyclones is used to dissolve the gas so as to increase water washing function. The same applies to thebaffles - The above baffles are arranged horizontally in alternating fashion in opposing directions and offset with respect to each other so that the fluid dissolution effect will be more significant. This also applies to the
baffles - In FIGS. 16 to 20 and 21 to 32, the invention provides a baffle assembly also applicable to a burning tower for establishing flame cyclones wherein the baffle assembly is installed in a washing tower, and its functions are the same as those described above, and the related descriptions are therefore omitted. However, the baffles applicable to the burning tower are made of heat-resistant material or constructed by U-shaped water
hollow wall panel 24A orU-shaped water wall 24, inside whichwater wall 24 is preferably comprised of a plurality of heat-resistant tubes and arranged in the form of U shape, as shown inFIGS. 16-20 . Anair inlet 11 is disposed on one side of a sealedburning tower 9 and anair outlet 12 is disposed on another side of the burningtower 9. The burningtower 9 includes a control valve (not shown) and a diversion panel (not shown) disposed proximate to theair inlet 11 for adjusting the flow and generating a linear acceleration to the gas entering the burningtower 9 respectively. Further, the bottom of the burning tower includes a blower (not shown), and a plurality of multiple layers of baffles arranged in alternating fashion in opposing directions and each layer of baffles are offset with respect to the upper or lower layer baffles thereof all of which are disposed at about center of the burningtower 9 to form the transverse baffle assembly 20 (see FIGS. 16 to 20). - Due to the negative pressure established by the speed difference, the gap can hold the fluid current, so that the fluid current can be mixed quickly into the combustion, and further collects the remainders of the combustion for the cyclonic combustion at the baffle assembly comprised of a combination of cyclonic baffles. Many double-side twin cyclones are established to increase the holdup time of the fluid current for providing a complete combustion. In addition, the internal side of the
baffle assembly 22 or thebaffle assembly 19 can collect a large amount of turbulent burning waves. If the burning-flame current is situated in thebaffle assembly baffle 22 or thebaffle 19 increases unsettled combustion. If the air for the combustion flows backward, the holdup time will increase. The gap situated in a plurality ofbaffles 22 or baffles 19 comprised of a plurality of water walls 24 (or waterhollow wall panels 24A) allows the flame to go through the gap in thebaffle assembly 20, and the gap can be used for enhancing the stability of discharging air and preventing clog from occurring. This also applies to thebaffles - Referring to
FIG. 20 , a preferred embodiment of the invention is shown. This embodiment comprises avertical boiler 9 havingseveral baffle assemblies 20 of different shapes and multiple layers arranged as described above. Abaffle space 27 is defined by the baffle assembly comprised of the plurality ofwater walls 24 or waterhollow wall panels 24A as mentioned above for accommodating the flames from theigniters 17 and fixing theigniters 17 at the entrance of thebaffle space 27 of the boiler, and an inlet wind zone or ablower 41 preferably disposed on aninlet duct 11 and connected to theboiler 9. Theigniters 17 are provided for combustion so that fuel can enter into thebaffle space 27 of theboiler 9. Theboiler 9 is comprised of a plurality of water walls 24 (or waterhollow wall panels 24A) disposed thereon, and the exhaust of combustion is discharged upward along thebaffle space 27 in a cyclonic manner and downward at an angle of 180 degrees, and then moved to a boiler tube comprising a series ofbaffle spaces 27. At this stage, heat exchange is conducted at the water walls 24 (baffle space 27) to cool the discharged air passing through the tubes of the boiler. These tubes are radially connected to the top and bottom of each steam drum. The discharged gas will pass through anexhaust passage 12 and a chimney and leaves this unit. Theblower 41 is forced to supply air to facilitate the airflow for the combustion and provide a static pressure to overcome the resistance caused by the exhausts of the boiler and pass the burning gas through the chimney to the outside. The number and the diameter of the tube of thewater wall 24 as well as the shape, arrangement, separation and material of the baffles are selected according to the fluid flow and heat transfer of the industrial standard in order to achieve the required pressure drop of the water/steam and the required heat absorption from the chimney passage so as to minimize the amount of NOx produced during the burning process. This also applies to thebaffles - A plurality of water walls 24 (or water
hollow wall panels 24A) constitute an assembly with baffles inside and form abaffle assembly 20 for passing the air separately to a previous layer or a next layer and communicating the air to theblower 41 by passing the turbulent air through the gap so as to cause the air to enter thebaffle space 27 of the boiler. The heat discharge rate is restricted to minimize the amount of NOx produced. In the meantime, combustion is conducted at an empty layer (or a secondary combustion chamber) in thebaffle space 27 of the boiler. Thus, carbon monoxide can be combusted completely. This also applies to thebaffles - In
FIGS. 16, 17 , 15 and 11, air is introduced from theair inlet 11 connected to theblower 41 below and blocked by thediversion panel 14, and then entered into theprimary combustion chamber 28 along thediversion panel 14. As a result, a first wave burning is established, and the heavier particles are gathered and held at the bottom of the tank such that it can burn thegas fuel 25 more completely. - In
FIGS. 15 and 11 , an angular of baffle change (of a corner rounding angle) greater than 90 degrees is made when the current flows through thebaffle assemblies 20 so that the current establishes a plurality of double-side twin cyclones by the combustion. If the flame reaches the position of abaffle 22 or abaffle 19, the turbulent flame is blocked to help the combustion of the burning gas so as to completely combust all hard-to-burn gas remained therein. This also applies to thebaffles - In
FIGS. 17, 18 , 19, 6 and 14, the diversion panel in the burningtower 9 serves as a diversion for the air and forces the gas to enter from the air inlet above through thebaffle assembly 20 and perform a gas-fire melting at the baffle 21 (18) and the baffle 22 (19) so as to burn the liquid fuel or thesolid fuel 26 in theprimary combustion chamber 28 wherein the flame rises, and the wind blows in high speed downward to oppose each other and increase the holdup time. The rising warm current and the high-speed wind form opposite currents to create a strong convection to rapidly expand the burning surface, so as to establish a flame twin cyclones in the baffle space 27 (seeFIG. 25 ) comprised of a plurality of baffle surfaces and define asecondary combustion chamber 29. The larger flame will remain at the gap of thebaffle 22 or thebaffle 19, and finally the gas is combusted completely, and the air is discharged from theair outlet 12 connected to the air-extractingblower 42. More specifically, multi-layer baffle assemblies are connected to form a whole combustion chamber and establish layers of flames. - A gas burning state or other burning state such as a wind blowing state or an upward burning at one or more openings of the top of a chimney effect tube 47 (see
FIGS. 16, 17 ) assists the combustion. In the gas burning state or the solid burning state, the liquid or solid at the second layer or the third layer expands the gap to form aprimary combustion chamber 28, and then the combustion continues to a fourth layer and a fifth layer, or a fifth layer and a sixth layer under a negative pressure attraction state to define asecondary combustion chamber 29. The baffle has an igniter disposed on its side, and the multi-cyclonic burning tower employs the diversion panel and baffle to establish a speed difference for the gas, and thus a negative pressure effect is established to increase the combustion efficiency by the single-side or double-side twin cyclones and hold up the twin cyclones at the burning baffle for a complete combustion. The twin flame cyclones at the baffles strengthen the cyclonic effect to provide a fairly complete combustion, and the twin flame cyclones will hold up for a longer time so as to enhance the complete combustion, reaction and energy efficiency. This also applies to thebaffles - In
FIGS. 16 , and 17 to 19, the invention has adiversion panel 14 disposed above or below each transversal baffle assembly at the top of the burning tower to provide more burning functions so that the gas entering into the burning tower can establish a linear acceleration, and the invention also includes a bottom tank disposed at the bottom for holding heavier particulates in the bottom tank, and the fuel pump (not shown) is used to pump fuel to thebaffle assembly 20 and the fuel is reacted with the air for the combustion. Theblower 40 draws gas upward or from the side such that the principle of using the high pressure to create a heat exchange can be applied to the plurality of water walls 24 (or waterhollow wall panels 24A), and the cold and hot air are in heat convection each other to allow the gas remained therein to burn more easily. The dragging force produced by the twin cyclones can be used for burning the gas evenly. This also applies to thebaffles - The transversely arranged baffle assembly comprises a plurality of baffles arranged horizontally in alternating fashion in opposing directions and offset vertically with respect to each other to form a plurality of
baffle spaces 27 in the baffle assembly to provide a better gas-liquid combustion effect. In the meantime, the baffle assembly shown inFIGS. 23 and 24 is a baffle structure with the combination of aU-shaped baffle 22 with canted corners and a 7-shapedbaffle 45 or the combination of a holding-arms-typeU-shaped baffle 19 and a hook shapedbaffle 46 offset and coupled with each other. The assembly forms a stairway-like baffle assembly wherein the functions and applications of this baffle assembly are the same as those of other baffle assemblies for establishing flame twin cyclones or washing twin cyclones by the baffle assemblies in different shapes. In the baffle assembly of the invention, the combination of an invertedU-shaped baffle 21 and an invertedU-shaped baffle 22, the combination of an invertedU-shaped baffle 22 and a rising-arms-typeU-shaped baffle 43, the combination of a holding-arm-typeU-shaped baffle 19 and a holding-arm-typeU-shaped baffle 19, the combination of a holding-arm-typeU-shaped baffle 19 and a small-mouth-typeU-shaped baffle 18, the combination of rising-arms-type U-shaped baffles 43, the combination of invertedU-shaped baffles 21 or the combination of inverted-V-arm-type U-shaped baffles 44 is offset and kinked to form a whole baffle assembly disposed vertically or obliquely and provide the functions of a multi-cyclonic dust collector and an oil-gas separator. Alternatively, the baffle assembly can be disposed horizontally to establish twin cyclones fluid or liquid flows for the design of a washing tower or a burning tower. All of the above are intended to be covered within the scope of the invention. - Referring to
FIG. 25 , a plurality ofU-shaped baffles 22 each comprises a bottom 220, a firstcanted corner 221 at one end of the bottom 220, a secondcanted corner 223 at the other end of the bottom 220, oneside 222 connected to the firstcanted corner 221, and theother side 224 connected to the secondcanted corner 223 are shown. The plurality of two layersU-shaped baffles 22 are arranged horizontally in alternating fashion in opposing directions and offset vertically with respect to each other to form thebaffle assembly 20 of the invention. Also, openings of the oppositeU-shaped baffles 22 are offset with respect to each other. Moreover, the following three location relations must be met. - (A) A distance “A” between any two adjacent
U-shaped baffles 22 of the lower group must be substantially equal to a distance “A” between any two adjacentU-shaped baffles 22 of the upper group. This can balance inlet fluid and outlet fluid. - (B) A distance between one
side 222 of aU-shaped baffle 22 of the lower group and oneside 222 of aU-shaped baffle 22 of the upper group must be substantially equal to half of the distance “A” and a distance between theother side 224 of aU-shaped baffle 22 of the lower group and theother side 224 of aU-shaped baffle 22 of the upper group must be substantially equal to half of the distance “A”. This can facilitate fluid flow. - (C) A distance “B1” between the bottom 220 of a
U-shaped baffle 22 of the upper (the lower) group and a top end (a bottom end) of theother side 224 of aU-shaped baffle 22 of the lower (the upper) group or a distance “B2” between the bottom 220 of aU-shaped baffle 22 of the lower (the upper) group and a bottom end (a top end) of oneside 222 of aU-shaped baffle 22 of the upper (the lower) group must be less than a diameter of a cyclone C (e.g., C1, C2, C3 or C4) but greater than a radius thereof. - Air (or water) stream enters the baffle assembly from
gaps 225 having a length “A” each between two adjacentU-shaped baffles 22 of the lower group. The air stream is blocked by thebottoms 220 of the U-shaped baffles 22 of the upper group. As a result, two cyclones C1, C2 rotating in opposing directions are established inside the spaces ofbaffles 22. Next, for example, the cyclone C1 and C2 are simultaneously forced to pass agap canted corner 223, theother side 224 and thebottoms 220 of the U-shaped baffles 22 of the lower group. Likewise, a cyclone C4 is established simultaneously with the cyclone C3 and abutted the firstcanted corner 221, the oneside 222 and thebottoms 220 of the U-shaped baffles 22 of the lower group. Cyclones C3, C4 are rotating in opposing directions same as cyclones C1, C2. Particulates, dirt or the like in the high speed rotating air stream are accumulated on a first corner space 220A, asecond corner space 220B, and a portion of the bottom 220 between a contact point of the cyclone C3 and a contact point of the cyclone C4 due to its heavier weight. Then a clean air stream is formed by the cyclones C3, C4 and exits agap 227 between, for example, the oneside 222 and theother side 224 of a U-shaped baffles 22 of the upper group. Also, the accumulate particulates, dirt or the like are removed under occurrences of double-side twin cyclones C1-C4 by spraying or sprinkling water as described by referring to the description ofFIGS. 33 and 34 . - Referring to
