A pulse-jet cleaning device for bag filter dust collectors

Abstract

This utility model relates to a pulse-jet cleaning device for baghouse dust collectors, comprising an air supply unit, at least one conveying unit, at least one pulse-jet cleaning unit, and several regulating units. Its advantages lie in that the air supply unit supplies compressed gas at a stable pressure; the conveying units are connected to both ends of the pulse-jet cleaning unit to deliver compressed gas bidirectionally, resulting in a more balanced pressure distribution of the compressed gas in the pulse-jet cleaning unit, effectively removing dust while reducing damage to the filter bags, thus solving the problem of poor dust removal efficiency in pulse-jet cleaning devices; the regulating units adjust and stabilize the flow rate of the compressed gas and change part of the airflow pattern, not only guiding the compressed gas but also evenly dispersing or generating a rotating airflow pattern when the compressed gas enters the filter bag, thereby more gently and comprehensively shaking off the light, loose dust adhering to the inner wall of the filter bag, reducing impact damage to the filter bag, and allowing the dust to settle into the ash hopper more quickly.

Description

Technical Field

[0001] This utility model relates to the field of jet pipe technology, and in particular to a jet blowing device for bag filter dust collectors. Background Technology

[0002] Baghouse dust collectors are widely used in industrial dust treatment, especially in the dismantling of used refrigerators, where the crushing process generates complex mixed dust, including lightweight foam, fibers, plastic fragments, and metal powders. These dust particles are characterized by large density differences and irregular shapes, thus posing challenges to the cleaning process of traditional baghouse dust collectors' pulse-jet cleaning devices.

[0003] First, uneven pressure distribution of the pulse-jet airflow leads to poor dust removal or damage to the filter bags. Existing pulse-jet systems typically use a unidirectional conveying pipe structure. As the compressed gas flows unidirectionally along the pipe, the pressure gradually decreases, resulting in excessively high airflow pressure at the front end of the pipe, which can easily cause localized impact damage to the filter bags. Meanwhile, the downstream airflow pressure is insufficient, making it difficult to completely remove dust adhering to the surface of the filter bags, especially highly adhesive mixed dust. This uneven pressure distribution not only reduces dust removal efficiency but also shortens the service life of the filter bags.

[0004] Secondly, traditional jet cleaning methods are not adaptable to mixed dust. Existing jet cleaning technologies mostly rely on high-speed airflow in one direction. Because the dust generated from the dismantling of old refrigerators contains lightweight foam, fibers and other loose materials, it is easy for them to be re-entrained under the action of high-speed airflow, making it difficult to settle effectively. This results in incomplete dust removal or dust redispersement, affecting dust removal efficiency and equipment stability.

[0005] There are no effective solutions yet for the problems in related technologies, such as poor dust removal effect of pulse jet cleaning devices, easy damage to filter bags by pulse jet cleaning devices, and incomplete dust removal in a single airflow direction. Utility Model Content

[0142] How to use this utility model:

[0143] When pulse dust removal is required, the first valve element 13 is opened, and the compressed gas with stable pressure stored in the gas storage element 11 flows through the output element 12 to the corresponding first conveying element 21, and then flows to the second conveying element 22 and the third conveying element 23 respectively. Compressed gas is delivered to the fourth conveying element 31 from both ends, and then sprayed out through several first injection elements 32, which drives the surrounding air to enter the air inlet element 41 at a greater pressure. After the injection speed is adjusted by the contraction element 42, the compressed gas with stable pressure is evenly blown onto the filter bag by the diffusion element 43. Some of the compressed gas changes shape under the action of the turbulence element 45 and enters the filter bag in a rotating manner, thereby shaking off the dust from the filter bag.

[0144] The technical effects of this utility model are as follows:

[0145] The system utilizes a gas supply unit to provide compressed gas at a stable pressure. A conveying unit connects to both ends of the pulse-jet unit to deliver compressed gas bidirectionally, resulting in a more balanced compressed gas pressure distribution within the pulse-jet unit. This effectively removes dust while minimizing damage to the filter bags, solving the problem of poor dust removal efficiency in pulse-jet systems. An adjustment unit regulates and stabilizes the flow rate of the compressed gas and alters the airflow pattern. This not only guides the compressed gas but also creates a uniform diffusion or slightly rotating airflow pattern as it enters the filter bag. This more gently and thoroughly shakes off the light, loose dust adhering to the inner wall of the filter bag, reducing impact damage and allowing dust to settle into the ash hopper more quickly. This solves problems such as pulse-jet systems easily damaging filter bags and incomplete dust removal due to a single airflow direction.
