Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a waterproof polyester filter bag for boiler dust removal equipment. Background Art

[0002] As an important thermal energy equipment, boilers are widely used in many industrial fields such as electricity, chemical industry, and metallurgy. However, in the process of boiler combustion, a large amount of smoke and particulate matter will inevitably be generated. If these harmful substances are not effectively treated, they will seriously pollute the environment and endanger human health. Therefore, boiler dust removal technology has become a key link in ensuring environmentally friendly emissions in industrial production. Traditional boiler dust removal methods mostly use electrostatic dust removal, wet dust removal and other methods, but these methods have problems such as high energy consumption, low dust removal efficiency, and high maintenance costs. In recent years, with the continuous development of bag filter dust removal technology, its high efficiency, low resistance, and easy maintenance characteristics have gradually been recognized, becoming an important research direction in the field of boiler dust removal. Bag filter dust removal equipment filters dust-containing gas through filter bags, so that dust particles are blocked inside the filter bags, thereby achieving the purpose of dust removal. As the core component of bag filter dust removal equipment, the performance of the filter bag directly affects the dust removal effect and the stability of equipment operation.

[0003] When some existing filter bags are in use, a cleaning component is provided inside the filter bag to clean the inner wall of the filter bag. The smoke and particulate matter in the flue gas will not only be adsorbed on the inner wall of the filter bag, but also adhere to these components, which may easily affect the normal use of the cleaning component.

[0004] For example, a boiler-specific filter bag with high-efficiency dust removal disclosed in announcement number CN219333501U is equipped with components such as filter bags, rotating fans and soft brush plates. When the gas inside the boiler needs to be filtered and discharged through the filter bags, the gas passes through the dust removal equipment and then flows from the second flange to the inside of the first flange. At this time, the movable rotating fan inside the first flange rotates under the impetus of a strong airflow, and at the same time drives the rotating shaft to rotate, so that the soft brush plates symmetrical on both sides of the rotating shaft rotate, so that the inner wall of the filter bag can be scraped without the need for electric drive, thereby avoiding a large amount of dust adhering to the inner wall of the filter bag.

[0005] However, this patent arranges components such as a rotating fan and a soft brush plate inside the filter bag. When smoke enters the filter bag, the smoke and particulate matter therein will adhere to these components, which may easily affect the normal use of these cleaning components.

[0006] Therefore, it is necessary to invent a waterproof polyester filter bag for boiler dust removal equipment to solve the above problems. Utility Model Content

[0010] Preferably, a convex tooth is fixedly connected to the surface of the vibration wheel, and the convex tooth is in contact with the side wall of the filter bag body.

[0011] When the vibration mechanism moves up and down, the rotating wheel will rotate on the load-bearing ring, and the convex teeth on the surface of the vibration wheel will knock and vibrate the filter bag body.

[0017] Open the discharge valve to discharge the dust particles inside the dust hopper through the discharge pipe.

[0018] Preferably, the top and bottom ends of the filter bag body are both open-type designs, and a polytetrafluoroethylene film is provided on the outer side wall surface of the filter bag body.

[0020] Preferably, a sliding bearing is provided at the connection between the connecting block and the limiting sliding rod.

[0021] The setting of the sliding bearing enables the connecting block to slide up and down along the limiting sliding rod more smoothly.

[0022] Preferably, sealing rings are provided at the connection between the filter bag body and the annular top plate and at the connection between the filter bag body and the annular bottom plate.

[0023] The sealing ring is provided to improve the air tightness between the filter bag body and the annular top plate and the annular bottom plate to prevent smoke from escaping from the gaps.
