Small filter cartridge dust collector

A small filter type dust collector is composed of a filter cartridge as a filtering element or uses a pulse jet dust collector. The filter cartridge dust collector can be divided into oblique insertion type, side mounted type, lifting type, and top mounted type according to the installation method. Filter cartridge dust collectors can be divided into long fiber polyester filter cartridge dust collectors, composite fiber filter cartridge dust collectors, anti-static filter cartridge dust collectors, flame retardant filter cartridge dust collectors, membrane covered filter cartridge dust collectors, nano filter cartridge dust collectors, etc. according to the material of the filter cartridge.

Small filter type dust collectors have the advantages of small size, high efficiency, low investment, and easy maintenance. However, due to their small equipment capacity, it is difficult to combine into high air flow equipment, low filtration wind speed, and narrow application range, which are only used in industries such as grain and welding. Therefore, they have not been widely promoted for many years. In recent years, with the continuous development of new technologies and materials, represented by companies in Japan and the United States, the structure and filter material of dust collectors have been improved, making filter cartridge dust collectors widely used in industrial fields such as cement, steel, electricity, food, metallurgy, and chemical industry. The overall capacity has increased several times, becoming a large dust collector with a filtration area greater than 2000m2 (GB6719-86 category). It is the best solution to solve the problem of difficult collection of ultrafine dust, high filtration wind speed, poor dust cleaning effect, easy wear and leakage of filter bags, and high operating costs for traditional dust collectors. Compared with various types of bag and electrostatic dust collectors on the market, it has the advantages of large effective filtration area, low pressure difference, low emissions, small volume, and long service life. These characteristics have become a new direction for the development of industrial dust collectors. The structure of a filter cartridge dust collector is composed of an inlet duct, an exhaust duct, a box body, an ash hopper, an ash cleaning device, a guide device, an airflow distribution plate, a filter cartridge, and an electrical control device, similar to the pulse bag dust removal structure of an air box.

The arrangement of small filter type dust collectors is very important, which can be vertically arranged on the box flower board or obliquely arranged on the flower board. From the perspective of dust removal effect, vertical arrangement is more reasonable. The lower part of the flower board is a filtering chamber, and the upper part is an air box pulse chamber. An airflow distribution plate is installed at the inlet of the dust collector.
