The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1 and 2, a steam humidifying and dust removing device according to a preferred embodiment of the present application includes a cyclone dust collector 1, a humidifying pipe 2, a centrifugal fan 3, a plurality of steam spray heads 4, a plurality of metal filter screens 5 and a pressurizing water gun 6. The cyclone dust collector 1 has an air inlet pipe 11, an air outlet pipe 12 and a dust collecting port 13. One end of the humidifying pipe 2 is connected to the air inlet pipe 11, and the humidifying pipe 2 is arranged to extend obliquely upward from one end and then bent vertically downward to the other end. The centrifugal fan 3 is arranged on the air outlet pipe 12. The steam spray heads 4 are arranged in the pipe wall at one end of the humidifying pipe 2 at intervals and are used for introducing steam water mist into the humidifying pipe so that small particle dust and the water mist collide and gather to form large particle dust. The metal filter screens 5 are arranged in the air outlet pipe 12 at intervals and are used for removing dust particles in cooperation with the cyclone dust collector 1 so as to improve the dust removal efficiency. The pressurizing water gun 6 is arranged at a bending position in the humidifying pipeline 2, and a muzzle of the pressurizing water gun faces the air inlet pipe 11 and is used for flushing and removing dust particles adhered to the inner wall of the humidifying pipeline 2.
According to the scheme provided by the embodiment of the utility model, a certain amount of steam water mist is introduced into the humidifying pipeline through the steam spray heads 4, small particle dust in the waste gas flow can be gathered to form large particle dust, and then the dust particles are removed through the cyclone dust collector 1 and the metal filter screen 5, so that the dust removal efficiency is improved. Meanwhile, as the steam water mist is added, dust particles are easy to adhere and accumulate on the inner wall of the humidifying pipeline 2 due to moisture, the humidifying pipeline 2 is easy to be blocked, and the dust particles adhered on the inner wall of the humidifying pipeline 2 are flushed and removed through the pressurizing water gun 6 arranged in the humidifying pipeline so as to prevent the humidifying pipeline from being blocked. One end of the humidifying pipeline 2 is arranged obliquely downwards, so that steam and water mist can be prevented from being collected and water sprayed by the pressurized water gun 6 flows backwards, and meanwhile water is collected and flushed conveniently.
The following is a detailed description of specific embodiments:
Referring to fig. 2, in the present embodiment, the plurality of steam showerheads 4 are axially spaced along the humidifying pipe 2. In another embodiment, the steam spray heads 4 are spirally distributed along the axial direction of the humidifying pipeline 2, so that steam water mist introduced into the humidifying pipeline can be distributed more uniformly, and small particle dust in the exhaust gas flow can be well collided with the water mist to form large particle dust so as to improve the subsequent dust removal efficiency.
Referring to fig. 3, the cyclone dust collector 1 further includes a cylindrical portion 14, a conical portion 15, and a dust collecting box, and an air inlet pipe 11 and an air outlet pipe 12 are provided on the cylindrical portion 14. The conical portion 15 is provided below the cylindrical portion 14 and communicates with the cylindrical portion 14, and a dust collection port 13 is provided at the bottom thereof. The dust box is arranged below the dust collecting opening 13.
The waste gas air flow enters the cyclone 1 after being humidified by the steam water mist through the humidifying pipeline, large-particle dust with larger mass is separated from the air flow and is trapped on the wall of the cyclone 1, the large-particle dust slides into the dust collection box from the dust collection port 13 along the conical part 15 to be discharged due to the action of gravity, the small-particle dust rises along with the rotation of the air flow to enter the air outlet pipe 12, the small-particle dust is filtered under the blocking action of the metal filter screens 5, and finally clean air is discharged from the air outlet pipe 12.
The mesh density of the metal filter screens 5 gradually increases from one end of the air outlet pipe 12 extending into the cylinder portion 14 to the other end. The metal filter screen 5 on the lower layer has larger gap density, and the metal filter screen 5 on the upper layer has smaller gap density, gradually filters out dust with gradually smaller particles through multiple layers, can ensure the filtering effect, and can ensure that the metal filter screen 5 cannot be blocked to influence the normal passage of air flow. The metal filter 5 may be provided in a form of being drawn out and removed for easy replacement, which is not limited herein.
Since the steam mist introduced into the humidifying pipe is also diffused into the cyclone 1 to wet the inside thereof, there is also a phenomenon that large particle dust adheres to the inner wall of the conical portion 15 during the separation and collection. Therefore, a plurality of collecting convex strips 16 are arranged on the inner wall of the conical part 15 at intervals along the circumferential direction, and the cross section of each collecting convex strip 16 is of an arc-shaped structure protruding outwards. The arrangement of the collecting raised strips 16 can better enable the steam water mist carrying large-particle dust to be collected into fine water flow along the protrusions in the middle of the collecting raised strips 16 to two sides so as to discharge dust particles from the dust collecting port 13. At the same time, the high-pressure water sprayed by the pressurized water gun 6 flows downwards along the inner walls of the cylinder part 14, the conical part 15 and the collecting convex strips 16, so that dust particles adhered to the inner wall of the conical part 15 are washed to clean the inside of the cyclone dust collector 1.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
