Device integrating centrifugal pre-dedusting and uniform distribution of air flow

Abstract

The invention discloses a device integrating centrifugal pre-dedusting and uniform distribution of gas flow. The device comprises a cylinder, the top of the cylinder is a closed end, and the bottom of the cylinder is an opening end. One exhaust pipe stretches out of the top of the cylinder, a tapered deflector is arranged over the exhaust pipe, and the tapered deflector is supported by a supporting piece fixed to the top of the cylinder. A hollow tapered insertion piece is arranged on the bottom of the cylinder, the insertion end of the hollow tapered insertion piece is supported by a supporting piece fixed to the inner wall of the bottom of the cylinder, a circular seam is formed between the inner wall of the bottom of the cylinder and the outer side wall of the insertion end of the tapered insertion piece, and a flue gas flow inlet connected with a gas outlet of a gas inlet pipeline is formed in the side face of the cylinder. According to the device, centrifugal pre-dedusting and uniform distribution of the gas flow are combined integrally, the overall operating cost of the device is greatly reduced, the operating effects are improved, the service life of filter bags is effectively prolonged, and the operating effects of the filter bags are improved, the gas flow distribution of flue gas and the flow distribution coefficients of the filter bags are more uniform, and reentrainment of dust and blocking of the gas inlet pipeline are not easily caused.

Description

technical field [0001] The invention relates to the field of dust collector components, in particular to an integrated device for centrifugal pre-dust removal and airflow uniform distribution applied to a cylindrical dust collector. Background technique [0002] In recent years, due to the advantages of high dust removal efficiency, good reliability, and low operation and maintenance costs, the bag filter has been widely used in metallurgy, chemical industry, building materials, thermal power and other industries. not exactly. So far, most of the cylindrical bag filter produced by major dust collector manufacturers adopts the traditional air intake guide device, that is, the air intake pipe extends into the dust collector box, and the bottom of the pipe section inside the box is cut. It is stepped, and the pipe section is made of perforated plate, so that the air flow can spread evenly around and play the role of uniform air flow. The body produces direct flushing, and at ...

Problems solved by technology

[0009] The purpose of the present invention is to solve the problem that the existing air intake guide device makes the airflow of the cylindrical bag filter flow into the ash hopper, which is easy to induce secondary dust, uneven distribution of internal airflow, easy damage of filter bags by the impact of airflow, and the flow rate of each filter bag. To solve problems such as uneven distribution coefficient and easy blockage of the intake pipe, an integrated device for centrifugal pre-dust removal and uniform air distribution is provided
