Venturi injection pipe for dust remover

Abstract

The invention discloses a Venturi injection pipe for a dust remover. The Venturi injection pipe comprises a diffusion pipe, Venturi nozzles and filter drums; air outlet holes are formed in the diffusion pipe; the upper end of each Venturi nozzle is fixedly arranged on one air outlet hole; a lower opening of each Venturi nozzle is arranged above an opening of one filter drum; each Venturi nozzle comprises a shell, a jet pipe and reinforcing ribs; each shell is a hollow column body; an upper opening and a lower opening of each shell are shaped like an outwards-expanded horn; the center of each shell is provided with one jet pipe; the periphery of each jet pipe is fixed together with the outer wall of one shell by using the plurality of reinforcing ribs; and spaces in each jet pipe and one shell are partitioned into a plurality of drainage air passages by the reinforcing ribs.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment design, in particular to a Venturi blowing pipe used for dust collectors. Background technique [0002] In the field of industrial dust removal technology, filter dust collectors are usually used to quickly physically separate dust particles in the air. This filter dust collector usually includes a shell and a blowing device. Including blowing pipe, pulse valve and gas storage tank. The blowing pipe is set at the opening of the filter. When the dust collector works for a period of time, more dust particles will be adsorbed on the filter to affect the filtration efficiency. At this time, the pulse valve is opened and the gas is stored The compressed gas in the tank quickly enters the filter from the blowing pipe to remove the dust particles adsorbed on the surface of the filter. [0003] At present, common industrial filter dust collectors include two categories: bag filter and cart...

AI Technical Summary

Problems solved by technology

[0006] 1) The dust cleaning in the area with insufficient force is not good, it is easy to cause the particle layer adsorbed and accumulated in the alveolar to be difficult to clean, resulting in continuous increase of filtration resistance and failure of the filter tube;

[0007] The area where the force is too large will easily lead to excessive deformation of the teeth. On the one hand, it may cause the particle layer to envelop the particle layer under the action of the reverse airflow, which will cause difficulty in cleaning due to the deformation of the alveolar; on the other hand, it will cause the tooth top of the alveolar Abnormal damage due to fatigue damage caused by excessive deformation of the root and tooth root, which seriously affects the performance, life, efficiency and economy of the filter tube
