Abstract

The invention provides a bag-type dust collector, which includes a box body, a pattern plate is arranged in the box body, and the box body is divided into an upper clean air chamber and a lower box body, the lower box body is provided with a plurality of ash hoppers, and the lower box body is provided with an air inlet The bell mouth, the flower plate is provided with several filter bags, the air inlet bell mouth and the lower box are provided with a deflector, the deflector includes a front deflector and a rear deflector, and the front deflector has a cross section of It is composed of semicircular guide grooves, the rear guide plate is composed of semicircular guide grooves with straight plates tangent to it on both sides, and the guide grooves of the front guide plate and the rear guide plate are divided into two parts. The openings are all facing the direction of the air inlet bell mouth, and both ends of the deflector are bent along the direction of the flue gas and have transition arcs. By changing the structure and installation arrangement of the deflector, the flue gas can enter Before the dust chamber, the large particles are subjected to inertial sedimentation, and it has stronger rigidity and greatly reduces the amount of deformation. It can also better realize the secondary distribution of the flue gas, and avoid the phenomenon of bag breaking due to excessive concentration of the flue gas. .

Description

technical field

[0001] The invention relates to a bag-type dust collector, in particular to a bag-type dust collector with an air intake guide plate with a special structure, and belongs to the technical field of dust collectors. Background technique

[0002] The bag filter plays an important role in the field of environmental protection, and the deflector is one of the important components of the dust collector, which is used to guide and optimize the airflow of the smoke and dust. Due to the large inlet speed of the smoke and dust particles entrained, If it is in direct contact with the filter bag, the scouring of high-speed flue gas will increase the load of the filter bag, aggravate the wear of the filter bag and reduce the dust removal efficiency, which will lead to extensive damage to the filter bag, uneven distribution of air flow and pressure, resulting in a large dust removal efficiency of the dust collector. reduce.
