Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a spray angle adjustment device for a smoke-proof and dust-removing water film dust collector. Background Technology

[0002] A water film dust collector is a device that uses a water film to adsorb and remove dust. Dust-laden gas enters tangentially from the bottom of the cylinder. As it rotates and rises, dust particles are thrown towards the inner wall by centrifugal force and captured by the water film formed on the inner wall of the cylinder by the water supply at the top. Some large particles will also sink into the water due to inertial collision. Its structure mainly includes a cylinder, a water injection tank or nozzle for water supply, and an overflow hole for wastewater discharge. It can achieve a dust removal efficiency of over 98%, and can desulfurize, resist acid and alkali corrosion, and has a low cost. However, it has disadvantages such as high equipment cost, water consumption, potential water carryover, and insufficient treatment of fine particulate matter. It is widely used in industries such as power, steel, chemical, cement, and glass to purify dust and harmful gases in industrial waste gas, thus contributing to environmental protection.

[0003] Currently, when using water film dust collectors to remove dust from flue gas, water is sprayed out in a cone shape from nozzles to form a water film for dust removal. However, during the dust removal process, some fine dust particles that are not captured by the water film may move upward with the airflow and gradually deposit on the outer surface of the nozzle, forming a dust layer. If this dust accumulates near the nozzle orifice, it may reduce the orifice diameter, leading to reduced flow rate and uneven atomization, thus affecting the efficiency of the water film dust collector. Regular cleaning is required, which involves disassembly and other operations, making the cleaning process cumbersome and impacting the use of the dust collector. Utility Model Content

[0024] An auxiliary mechanism is provided on the water supply pipe 2 and the semi-circular plate 4. The auxiliary mechanism includes a first L-shaped plate 5 and two mounting plates 6. The first L-shaped plate 5 is fixedly installed on the rear surface of the water supply pipe 2. A second L-shaped plate 7 is fixedly installed on the left end of the first L-shaped plate 5. The two mounting plates 6 are fixedly installed on the front end of the right surface of the second L-shaped plate 7. The two mounting plates 6 are located on the left side of the semi-circular plate 4. Brush bristles 8 are fixedly installed on the adjacent surfaces of the two mounting plates 6. An installation groove 9 is opened inside the first L-shaped plate 5. A motor 10 is fixedly installed inside the installation groove 9. The front end of the motor 10 extends through to the rear surface of the semi-circular plate 4. The motor 10 is fixedly connected to the semi-circular plate 4.

[0025] Furthermore, the auxiliary mechanism also includes a solid cone nozzle 11. The lower surface of the semi-circular plate 4 is provided with a mounting hole 12. The upper end of the mounting hole 12 extends through to the upper end of the connector 3. The solid cone nozzle 11 is threadedly installed inside the mounting hole 12 on the semi-circular plate 4.

[0026] Furthermore, by driving the solid cone nozzle 11 to rotate via the motor 10, the spray angle can be dynamically adjusted according to the flue gas flow rate and dust concentration, making the water film coverage more uniform and enhancing the dust capture capability. When the machine stops, the brush bristles 8 can be used to automatically clean the outer surface of the solid cone nozzle 11 to prevent dust accumulation and scale solidification, reduce the risk of nozzle damage due to blockage, reduce cleaning time, and thus improve the cleaning efficiency of the dust collector.

[0027] Furthermore, a connecting groove 13 is provided inside the semi-circular plate 4, and the mounting hole 12 communicates with the interior of the connecting groove 13.

[0028] Furthermore, a total of three auxiliary mechanisms are provided, which are respectively installed on three sets of water supply pipes 2 and semi-circular plates 4.

[0029] Furthermore, an exhaust pipe 14 is fixedly installed on the upper right surface of the dust collection chamber 1, a smoke inlet pipe 15 is fixedly installed on the lower left surface of the dust collection chamber 1, and a drainage pipe 16 is fixedly installed on the lower right surface of the dust collection chamber 1.

During the use of this dust collector, when it is necessary to adjust the spray angle of the solid cone nozzle 11, the operator starts the motor 10 through the control system. The motor 10 is located in the mounting groove 9 of the first L-shaped plate 5, and its output shaft is directly fixedly connected to the semi-circular plate 4. The rotation of the motor 10 drives the semi-circular plate 4 to rotate left and right around the axis of the connector 3.

At this time, the bristles 8 on the two mounting plates 6 at the front end of the second L-shaped plate 7 contact the outer surface of the solid cone nozzle 11. As the semi-circular plate 4 rotates, the bristles 8 continuously wipe the outer surface of the solid cone nozzle 11, brushing away the dust and impurities on the surface of the solid cone nozzle 11, causing the solid cone nozzle 11 to swing back and forth to clean it.
