[0002] Waste gas treatment mainly refers to the treatment of industrial waste gas such as dust particles, smoke, odorous gases, and toxic and harmful gases generated in industrial places. Inorganic waste gas is generally treated by liquid spraying to dissolve harmful substances in the inorganic waste gas in the liquid, thereby achieving the purpose of separating harmful substances from gases.

Moreover, the horizontal position of the spiral blade is also fixed, making it difficult to make all the inorganic waste gas produce swirl. Utility Model Content

[0027] Embodiment 1

[0028] A waste gas treatment spray swirl device comprises a body 1, an air inlet pipe 2 is arranged on the top of the body 1, an exhaust pipe 3 is arranged on the bottom of the body 1, a pipe 4 is rotatably arranged on the inner wall of the body 1, both ends of the pipe 4 penetrate the body 1 and extend to the outside, a spray head 5 is arranged at the bottom of the pipe 4, a reciprocating rotating mechanism is arranged between the pipe 4 and the body 1, a bracket 6 is movably arranged on the inner wall of the body 1, a spiral blade 7 is rotatably arranged on the bracket 6 through a driving mechanism, the bracket 6 is connected to the reciprocating rotating mechanism, a waste liquid pool 26 is arranged on the lower part of the body 1, and a filter screen 27 is fixedly arranged on the inner wall above the waste liquid pool 26.

[0029] See also Figure 2 The inorganic waste gas enters the body 1 from the air inlet pipe 2, and the pipeline 4 can be connected to a liquid supply device or connected to the waste liquid pool 26 through a circulating pump. The liquid sprayed by the spray head 5 can contact the inorganic waste gas, thereby purifying the inorganic waste gas.

[0030] The reciprocating rotation mechanism includes a driving gear 8, a half gear 9, a first motor 10 and a driving shaft 11. The driving shaft 11 rotates on the surface of the body 1 and extends to the inside of the body 1. The half gear 9 is fixed to the surface of the driving shaft 11. The driving gear 8 is fixed to the surface of the pipe 4 and meshes with the half gear 9. The pipe 4 and the body 1 are connected by a reset structure. The first motor 10 is fixed to the surface of the body 1 through a frame. The output end of the first motor 10 is connected to one end of the driving shaft 11. The reset structure includes a collar 12 and a torsion spring 13. The collar 12 is fixed to the inner wall of the body 1, and the collar 12 is concentrically arranged with the pipe 4. The torsion spring 13 is fixed between the collar 12 and the pipe 4.

[0031] See also Figure 1 , 2 And 3, the first motor 10 can drive the driving shaft 11 to rotate, and the driving shaft 11 can drive the half gear 9 to revolve when rotating. When the half gear 9 rotates, the half gear 9 can drive the driving gear 8 to rotate. At this time, the driving gear 8 can drive the sprinkler head 5 to rotate through the pipe 4. In the initial state, the sprinkler head 5 is in an inclined state. When the half gear 9 just disengages from the surface of the driving gear 8, the sprinkler head 5 rotates to the maximum stroke. At this time, the position of the sprinkler head 5 is symmetrical with the initial position of the sprinkler head 5 about the driving shaft 11, and at this time, the pipe 4 can deform the torsion spring 13 inside the ring 12 to store energy. As the half gear 9 continues to rotate, the half gear 9 disengages from the surface of the driving gear 8. Driven by the torsion spring 13, the pipe 4 can drive the sprinkler head 5 to reset, thereby realizing the reciprocating swing of the sprinkler head 5.

[0032] The driving mechanism includes a protective shell 20, a connecting shaft 21, a main shaft 22 and a second motor 23. The protective shell 20 is fixed to the top of the bracket 6. The main shaft 22 and the connecting shaft 21 rotate on the surface of the bracket 6, and one end of the main shaft 22 and the connecting shaft 21 extends into the protective shell 20. The spiral blade 7 is fixed to the surface of the connecting shaft 21. The main shaft 22 and the connecting shaft 21 are connected through a transmission mechanism. The transmission mechanism includes a synchronous wheel 24 and a synchronous belt 25. The synchronous wheel 24 is fixed to the surface of the main shaft 22 and the connecting shaft 21, and the two synchronous wheels 24 are transmitted through the synchronous belt 25.

[0033] See also Figure 5 The second motor 23 can drive the main shaft 22 to rotate. When the main shaft 22 rotates, it can simultaneously drive the two connecting shafts 21 to rotate through the synchronous wheel 24 and the synchronous belt 25, so that the connecting shaft 21 can drive the spiral blade 7 to rotate. When the spiral blade 7 rotates, the inorganic waste gas can generate a vortex, and the droplets are driven to rotate by the vortex. The centrifugal force generated strengthens the contact between gas and liquid, thereby improving the efficiency of waste gas treatment.

[0034] Embodiment 2

[0035] In the above scheme, the reciprocating swing of the spray head 5 is achieved through the reciprocating rotation mechanism, which increases the contact area between the spray head 5 and the inorganic waste gas. However, the horizontal position of the spiral blade 7 is fixed, and it is difficult to make all the inorganic waste gas produce swirl. Therefore, in this embodiment, a connecting mechanism is set between the bracket 6 and the reciprocating rotation mechanism of the body 1. The connecting mechanism includes a swing arm 14, a traction shaft 15, a traction plate 16 and a guide groove 17. The guide groove 17 is arranged on the surface of the traction plate 16, and the traction plate 16 is vertically fixed to the inner wall of the bracket 6. The swing arm 14 is fixed to one end of the drive shaft 11 and fits the inner wall of the body 1. One end of the traction shaft 15 is fixed to the end of the drive shaft 11, and the other end of the traction shaft 15 is slidably set in the guide groove 17.

[0036] Please refer to Figure 4When the driving shaft 11 rotates, the driving shaft 11 can drive the traction shaft 15 to revolve through the swing arm 14. At this time, the movement trajectory of the traction shaft 15 is a circle. Since one end of the traction shaft 15 is located in the guide groove 17, the traction shaft 15 can drag the traction plate 16 to move laterally through the guide groove 17 when the traction shaft 15 revolves. In the initial state, the traction shaft 15 is at the lower end of the guide groove 17. When the traction shaft 15 rotates 90°, the bracket 6 moves laterally to the maximum stroke. At this time, the traction shaft 15 is located in the middle of the guide groove 17. As the traction shaft 15 continues to revolve 90°, the bracket 6 is reset laterally. At this time, the traction shaft 15 is located at the upper end of the guide groove 17. When the traction shaft 15 continues to rotate, the bracket 6 moves laterally in the opposite direction and resets again when it reaches the maximum stroke. Through the above process, the spiral blade 7 can be driven by the bracket 6 to perform synchronous horizontal reciprocating motion, thereby increasing the contact area between the spiral blade 7 and the liquid.

[0037] Two limiting protrusions 18 are fixedly provided on the inner wall of the body 1 , a slide groove 19 is formed between the two limiting protrusions 18 , and the bracket 6 is slidably provided in the slide groove 19 .

[0038] See also Figure 6 By setting two limiting protrusions 18, the movement trajectory of the bracket 6 can be limited within the slide groove 19, so that the bracket 6 can only move in the horizontal direction, and the lowest limiting protrusion 18 can support the bracket 6 as a whole to prevent gravity from affecting the driving process of the traction shaft 15 on the traction plate 16.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
