The exhaust gas accelerating section 202 is formed by gradually reducing the gas flow passage, see the diameter-reducing passage (diameter-reducing accelerating passage 204) in fig. 3, and it can be seen from the figure that the diameter-reducing accelerating passage 204 is a conical cavity with a lower width and an upper width, gas is introduced from the lower wide opening, extruded from the upper narrow opening, gradually accelerated from the wide to the narrow, and finally fed from the accelerating passage 203 into the inside of the self-rotating device 3.

Referring to fig. 4-6, this part is the key part of the present invention, because rotation is required without external power assistance such as a motor, the spinning of the present invention is accomplished by the swirling (vortex) of the gas in combination with mechanical parts (helical blades, which are similar to the blades of a fan).
As can be seen from fig. 4, the inside of the autogiration device 3 is divided into one intake chamber (exhaust gas intake chamber 310) and three vane chambers (upper spiral chamber 301, middle spiral chamber 306, lower spiral chamber 308), then, by modifying the passages between the four chambers into a reduced diameter structure (center reduced diameter passage 303, right inclined reduced diameter partition 305 and left inclined reduced diameter partition 309), and, in order to generate swirling flow (vortex flow), two reduced diameter outlets (right inclined passage 311 and left inclined passage 312) are provided at eccentric positions, that is, two outlets, one near one side inner wall of the autogiration device 3 and the other near the other side inner wall of the opposite autogiration device 3, see fig. 6, it can be seen that when exhaust gas enters the chamber 310 from the left inclined passage 312 into the lower spiral chamber 308, the first is to be accelerated (reduced diameter passage), the second is to directly strike on the left inner wall and the lower layer spiral vane 307, so after the airflow strikes the side wall, a spiral vortex is formed to rotate the lower layer spiral vane 307, thus, the air entering the right inclined channel 311 is sent into the middle layer spiral chamber 306, and the air entering the middle layer spiral chamber 306 strikes the right side wall of the self-rotating device 3, so that not only the vortex is continuously formed, but also the air can be continuously accelerated, and the air is spirally struck on the middle layer spiral vane 304 to rotate, finally, the rotating vortex air enters the upper layer spiral chamber 301 after being accelerated for the third time through the central diameter reduction channel 303, the upper layer spiral vane 302 is pushed to rotate in the upper layer spiral chamber 301, the thrust in the form of vortex is subjected to the sequence of three diameter reduction, the vortex is always kept to rotate in the same direction, and the upper layer spiral vane 302 is pushed, the middle layer spiral blade 304 and the lower layer spiral blade 307 rotate in the same direction, and the upper layer spiral blade 302, the middle layer spiral blade 304 and the lower layer spiral blade 307 rotate in the same direction with the self-rotating device 3 to form a self-rotating mode.
The outer edges of the upper layer spiral blade 302, the middle layer spiral blade 304 and the lower layer spiral blade 307 are fixedly arranged with the inner wall of the self-rotating device 3, and the fixing mode is to bring the self-rotating device 3 to complete rotation when the upper layer spiral blade 302, the middle layer spiral blade 304 and the lower layer spiral blade 307 rotate in the same direction.
The self-rotating device is internally provided with 3 speed-increasing steering nozzles, is of a structure which gradually reduces from bottom to top, and can adjust the speed direction of the air inlet/dust collecting two-in-one device while increasing the air flow speed. The 3 speed-increasing steering nozzles are arranged on a plane, one direction is arranged on the left side, the other direction is arranged on the right side, and the third direction is arranged in the middle. And each stage of speed-increasing steering nozzle corresponds to the bottommost end of the spiral blades, the spiral pitch of the 3 groups of spiral blades is the same, and the lead number is gradually decreased from bottom to top.
The tree-shaped gas-solid separation device 6 is divided into an upper part and a lower part by an exhaust pipeline 7, and as can be seen from fig. 7, the exhaust pipeline 7 is a communicating pipeline which is communicated with the inside of the self-rotating device 3 (the top of the upper spiral cavity 301) and the outside of the tree-shaped gas-solid separation device 6 (the gas-solid separation outer cavity N), meanwhile, the exhaust pipeline 7 is a fixed connecting piece which is fixedly arranged on the tree-shaped gas-solid separation device 6 at the top of the self-rotating device 3, and as can be seen from fig. 7, the exhaust pipeline 7 is a plurality of irregularly arranged exhaust pipelines, and as the top end of the self-rotating device 3 is blocked, the gas in the self-rotating device 3 can only be sent into the gas-solid separation outer cavity N through the exhaust pipeline 7.
The outer surface of the upper part of the tree-shaped gas-solid separation device 6 is fixedly connected with the inner tile of the bearing 5, the outer tile of the bearing 5 is fixedly connected with the outer box body 4, as shown in fig. 2 and 7, the tree-shaped gas-solid separation device 6 rotates in the outer box body 4 relatively to the outer box body, and the parts of the outer walls of other tree-shaped gas-solid separation devices 6 and the inner wall of the outer box body 4 without the bearing basically adopt a sliding friction mode.
The outer wall of the lower part of the tree-shaped gas-solid separation device 6 is provided with a tree-shaped separation structure 8, the lowest tree-shaped separation structure 8 covers the waste gas accelerating part 202, as can be seen from fig. 8, the tree-shaped separation structure 8 of the invention has four stages, the outer diameters of the first layer of tree-shaped separation structure, the second layer of tree-shaped separation structure, the third layer of tree-shaped separation structure and the fourth layer of tree-shaped separation structure are distributed in an equidifferent number row, and the intervals among the tree-shaped structures of each stage are gradually increased to be distributed in an equidifferent ratio row. Because of the characteristic of the tree structure, when the flue gas flows from top to bottom, the gap between the tree-shaped separation structures 5a-5d and the inner wall of the outer box body is gradually reduced, which is beneficial to speed increasing.
A gas backflow cavity X is arranged between the inner wall of the tree-shaped gas-solid separation device 6 and the outer wall of the self-rotating device 3, and a gas inclined backflow cavity Z is arranged between the inner wall of the tree-shaped separation structure 8 at the bottommost part of the tree-shaped gas-solid separation device 6 and the outer wall of the waste gas accelerating part 202. As can be seen from fig. 2, the exhaust gas channel M, the inner cavity of the self-rotating device 3, the exhaust pipe 7, the gas-solid separation outer cavity N and the gas backflow cavity X are gas flowing cavities, the solidified matters formed in the gas-solid separation outer cavity N can be settled to the ash accumulation bin Y, when the solidified matters in the ash accumulation bin Y are more, the gas-inlet/dust-collecting two-in-one device 2 is detached and is dumped, and then the gas-dust separation is continuously carried out.
The invention has the working principle that the flue gas enters the equipment from the lower gas injection acceleration area of the air inlet/dust collection two-in-one device, and the part has a structure of gradually shrinking from the lower part to the upper part, so that the increase of the flow velocity can be realized, and the air flow enters the self-rotating device after the 1-level acceleration. The self-rotating device is provided with 3 speed-increasing steering nozzles, is of a structure which gradually reduces from bottom to top, and adjusts the speed direction of the air inlet/dust collecting two-in-one device while increasing the air flow speed. The 3 speed-increasing steering nozzles are arranged on a plane, one direction is on the left side, the other direction is on the right side, and the third direction is in the middle. And each stage of speed-increasing steering nozzle corresponds to the bottommost end of the spiral blades, the spiral pitch of the 3 groups of spiral blades is the same, and the lead number is gradually decreased from bottom to top. After being regulated by the speed-increasing steering nozzle, the original air flow in the center direction in the self-rotating device can move to the left side of the center line, and the speed-increasing steering nozzle is a small-aperture device, so that the air can be accelerated in the device for 2 stages. The gas is immediately discharged to the bottom end of the spiral blade corresponding to the outlet of the speed increasing device after being accelerated by the device, so that the self-rotating device is driven to start rotating. The gas continues to move upwards to the speed-increasing steering nozzle to form 3-stage speed increase, and the bottom ends of the spiral blades are blown after the gas flows out. Similarly, the gas moves up to the speed-increasing steering nozzle to form 4-stage speed increase, and the bottom end of the spiral blade is blown after the gas flows out, so that the initial speed of inlet flue gas is effectively utilized in the process, and the power problem of a rotary separation system formed by combining a self-rotating device, a gas channel/turbulence two-in-one device and a tree-shaped gas-solid separation device is ingeniously solved.
The gas channel/turbulent flow two-in-one device is composed of a self-rotating device, a tree-shaped gas-solid separation device, a bearing and a connecting piece provided with an outer box body. The self-rotating device and the tree-shaped gas-solid separation device form a coaxial structure. The outer diameter of the gas channel/turbulent flow two-in-one device is clamped into the inner ring of the bearing and is embedded into a groove at the top of the outer box body. The structure of the gas channel/turbulence assembly (the exhaust pipeline 7) is an upper elliptical lower circular structure with a half elliptical shape and a half circular shape, and the two gas channel/turbulence assemblies are divided into 12 layers (the upper 6 layers and the lower 6 layers are uniformly distributed in the cylinder at an included angle of 60 degrees between every two adjacent layers), and the two layers of gas channel/turbulence assemblies are distributed into a middle symmetrical structure, namely the upper layer of gas channel/turbulence assembly is an upper elliptical lower circular structure, and the lower layer of gas channel/turbulence assembly is a lower elliptical upper circular structure. The arrangement of two adjacent gas channels/turbulence assemblies between the upper and lower layers is shown as an included angle of 30 degrees. The flue gas passes through the gas channel/turbulence assembly from the inside of the self-rotating device and spans the purified gas discharging area (the gas backflow cavity X) and enters the gas-solid separation area (the gas-solid separation outer cavity N), and then the flue gas moves from top to bottom. The outer diameters of the annular end surfaces at the bottom of each layer of the tree-shaped structure from top to bottom are gradually increased, the outer diameters of the first layer of tree-shaped separation structure, the second layer of tree-shaped separation structure, the third layer of tree-shaped separation structure and the fourth layer of tree-shaped separation structure are distributed in an equispaced array, and the intervals among the tree-shaped structures at each layer are gradually increased to be distributed in an equispaced array. Because of the characteristic of the tree structure, when the flue gas flows from top to bottom, the gap between the tree separation structure and the inner wall of the outer box body is gradually reduced, which is beneficial to speed increasing. Meanwhile, the slope angle of the tree-shaped inclined plane is 45 degrees, so that the structure is in a rotating state during working, and particles on the tree-shaped inclined plane can be thrown away into the box body, so that the particles are prevented from being remained on the inclined plane. So that the purified gas has enough power to flow into the purified gas discharging area (gas reflux cavity X) from the gap between the tree-shaped gas-solid separation device and the gas inlet/dust collecting two-in-one device. In the process, the dust collection inclined plane of the air inlet/dust collection two-in-one device has the same angle with the tree-shaped separation structure, so that purified gas can be smoothly introduced into a gas discharge area (a gas reflux cavity X) after passing through the channel, and the gap between the two is between 30 and 40 mm. Meanwhile, the assembly gap between the self-rotating device and the air inlet/dust collecting two-in-one device is 1mm, so that the self-rotating device is ensured not to interfere with the air inlet/dust collecting two-in-one device in size during working, and the air entering from the air inlet/dust collecting two-in-one device is prevented from flowing out of the assembly gap while the tightness is ensured. The large agglomerated particles formed after passing through the rotary separation system fall from the gas-solid separation area (gas-solid separation outer chamber N) to the dust particle recovery area (dust bin Y) due to gravity. Finally, when the purified gas flows through the purification gas outer exhaust area (gas reflux cavity X) from the inner cavity of the tree-shaped gas-solid separation device to be exhausted to the atmosphere, the turbulent flow assembly with an upper elliptical structure and a lower elliptical structure is formed due to the action characteristic of double-layer symmetrical dislocation arrangement of the 12 gas channels/turbulent flow assemblies, so that the fine particles are promoted to collide and gather around the column again, the gathering and removal of the fine particles are realized, the emission is more standard, and the capturing is more efficient.

The structure of the gas channel/turbulence assembly is an upper elliptical lower circular structure with a half elliptical shape and a half circular shape, and the gas channel/turbulence assembly is divided into 12 layers (the upper 6 layers and the lower 6 layers are uniformly distributed in the cylinder at an included angle of 60 degrees between every two adjacent layers), and the two layers of gas channel/turbulence assemblies are distributed into a middle symmetrical structure, namely the upper layer of gas channel/turbulence assembly is an upper elliptical lower circular structure, and the lower layer of gas channel/turbulence assembly is a lower elliptical upper circular structure. The arrangement of two adjacent gas channels/turbulence assemblies between the upper and lower layers is shown as an included angle of 30 degrees. The structure has 2 functions, ① is used for introducing the flue gas from the inside of the cylinder of the self-rotating device (2) into the gas-solid separation area inside the equipment outer box body, and when ② purified gas flows through the purified gas discharging area from the inner cavity of the tree-shaped gas-solid separation device to be discharged to the atmosphere, the structure can be used as a turbulent column to realize collision and coalescence of fine particles after surrounding the column again, realize high-efficiency fine particle separation, and realize one piece of dual-purpose of a gas channel and a turbulent assembly.
Tree-shaped gas-solid separation device
The outer diameter of the annular end face at the bottom of each tree structure is gradually increased from top to bottom to form an arithmetic series distribution, and the intervals between the tree structures at each level are also gradually increased to form the arithmetic series distribution. The structure has 2 functions, ① shows a rotating state when the structure works, particles on the tree-shaped inclined plane can be thrown away into the box body to avoid remaining on the inclined plane, and the space between the ② tree-shaped structure and the inner wall of the outer box body is gradually reduced along with the increase of the size of the tree-shaped structure from top to bottom, so that the speed is increased, and purified gas can flow into a purified gas discharging area from the space between the tree-shaped gas-solid separation device and the air inlet/dust collecting two-in-one device with enough power.
The assembly gap between the self-rotating device and the air inlet/dust collecting two-in-one device is 1mm, so that the self-rotating device is ensured not to interfere with the air inlet/dust collecting two-in-one device in size during working, and meanwhile, the tightness is ensured, and the air entering from the air inlet/dust collecting two-in-one device is prevented from flowing out of the assembly gap.
