Technical Field

[0001] This utility model relates to the field of demisting and dust removal equipment, and in particular to a high-efficiency dual-cyclone tube bundle demisting and dust removal equipment. Background Technology

[0002] In current industrial production, exhaust gases contain a large amount of mist and dust, posing a serious pollution threat to the atmospheric environment. Traditional demisting and dust removal equipment includes a disc structure installed on the exhaust pipe, with multiple cylindrical demisting and dust removal devices mounted on the disc structure. The working principle involves a swirl plate at the bottom of the demisting and dust removal device, and spiral plates on the side with the opposite rotation direction to the swirl plate. After the exhaust gas passes through the swirl plate and undergoes a swirl, dust and mist droplets are drawn into the spiral plates with the opposite rotation direction by centrifugal force, no longer rising with the airflow, and thus fall and are discharged, achieving the effect of demisting and dust removal. However, during the spiral ascent of the exhaust gas, the rotational speed gradually decreases, and the centrifugal force on the dust and mist droplets also gradually decreases, resulting in an incomplete demisting and dust removal effect.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1-4 As shown in the figure, a high-efficiency dual-cyclone tube bundle 1 demisting and dust removal device of this embodiment includes a tube bundle 1, a cyclone plate 2 is provided at the bottom of the tube bundle 1, and a spiral drop plate 3 with the opposite rotation direction to the cyclone plate 2 is provided on the inner wall of the tube bundle 1. A guide fan blade 4 is provided on the upper side of the cyclone plate 2 in the tube bundle 1, and the rotation direction of the guide fan blade 4 is the same as that of the cyclone plate 2. The guide fan blade 4 in the tube bundle 1 can further enhance the cyclone effect on the airflow above the cyclone plate 2, making the airflow more uniform and stable, and the rotation effect will not be reduced. It ensures the centrifugal force of dust and mist droplets, so that dust and mist droplets can be more fully thrown into the spiral drop plate 3, thereby improving the demisting and dust removal effect.

[0019] Preferably, a drain hole 5 penetrating the side wall of the tube bundle 1 is provided on the lower side of the tube bundle 1. The position of the drain hole 5 is lower than the lower edge of the spiral drop plate 3. An upward guide cylinder 6 is provided on the inner side of the swirl plate 2. The upper side of the guide cylinder 6 is higher than the lower edge of the spiral drop plate 3. After dust and mist droplets enter the spiral drop plate 3, they can fall to the drain hole 5 for discharge. The upper surface of the swirl plate 2 can be set as an inclined surface, and the bottom of the inclined surface is the position of the drain hole 5, which can guide the dust and mist droplets to facilitate their discharge. The guide cylinder 6 can prevent the exhaust gas flow entering the tube bundle 1 from directly entering the spiral drop plate 3 and affecting the falling of dust and mist droplets.

[0020] Preferably, a cover ring 7 is provided on the upper side of the spiral drop plate 3 in the tube bundle 1. The width of the cover ring 7 is greater than the width of the spiral drop plate 3. The cover ring 7 can block the upper side of the spiral drop plate 3 to prevent dust and mist droplets on the upper side of the spiral drop plate 3 from being carried out by the airflow, thereby improving the defogging and dust removal effect.

[0021] Preferably, the cover ring 7 is fixed to the spiral drop plate 3 by countersunk screws 8. The cover ring 7 is provided with a sealing ring 9 that can cover the countersunk screws 8.

The elasticity of the sealing ring 9 can make the pressure ring 10 press against the hooks 12, thereby fixing the pressure ring 10. In this embodiment, the bottom edge of the pressure ring 10 is rounded to avoid damaging the sealing ring 9.

[0023] Preferably, both the upper and lower ends of the tube bundle 1 are provided with hexagonal fixing seats 13 connected to the disc structure. The tube bundle 1 and the fixing seats 13 are interlocked. Each edge of the fixing seat 13 is alternately provided with an inner plate 14 and an outer plate 15. The thickness of the inner plate 14 and the outer plate 15 is half the thickness of the fixing seat 13. When the fixing seats 13 are spliced, adjacent fixing seats 13 can be spliced ​​together by the cooperation of the inner plate 14 and the outer plate 15, reducing the leakage of exhaust gas at the splicing gap of the fixing seats 13.

[0024] Preferably, a connecting groove 17 is provided at the pointed corner of the fixed base 13, a connecting hole is provided at the connecting groove 17, and a connector 16 is provided at the connecting groove 17 to connect three adjacent fixed bases 13.
