Cyclone dust removal device

Abstract

The invention provides a cyclone dust removal device which comprises a cyclone cylinder, wherein an air inlet is formed in a top side face of the cyclone cylinder; an exhaust pipe stretching into thecyclone cylinder is arranged at the top of the cyclone cylinder; an ash bucket is arranged at the lower part of the cyclone cylinder; an inverted cone is arranged at the bottom in the cyclone cylinder; a gap is reserved between the periphery of the inverted cone and a conical cylinder part of the cyclone cylinder. According to the cyclone dust removal device disclosed by the invention, the separation efficiency of dust particles can be improved, and secondary back-mixing discharge of the dust is avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a cyclone dust removal device. Background technique [0002] Cyclone dust collector is a type of dust removal device. The dust removal mechanism is to make the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and collected on the wall of the device, and then the dust particles fall into the ash hopper by gravity. Each component of the cyclone dust collector has a certain size ratio. The change of each proportional relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the size of the air inlet, and the diameter of the exhaust pipe are the main influencing factors. . [0003] At present, the cyclone dust collector is generally composed of an intake pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. The cyclone dust co...

AI Technical Summary

Problems solved by technology

[0004] The existing literature and experiments on cyclone dust removal have proved that the diameter and insertion depth of the exhaust pipe have a great influence on the dust removal efficiency of the cyclone dust collector.

An appropriate value must be selected for the diameter of the exhaust pipe. The reduced diameter of the exhaust pipe can reduce the rotation range of the internal swirl flow, and the dust is not easily discharged from the exhaust pipe, which is beneficial to improve the dust removal efficiency, but at the same time, the speed of the air outlet increases and the resistance loss Increase; if the diameter of the exhaust pipe is increased, although the resistance loss can be significantly reduced, but because the exhaust pipe is too close to the wall of the cylinder, it is easy to form a "short circuit" phenomenon of the internal and external swirl, which makes the external swirl flow Part of the dust that has not been removed is directly mixed into the exhaust pipe and discharged, thereby reducing the dust removal efficiency

In addition, if the exhaust pipe is inserted too shallow, it is easy to cause the dust-laden airflow from the air inlet to enter the exhaust pipe directly, which will affect the dust removal efficiency; , so that the distance between the exhaust pipe and the bottom of the cone is shortened, and the chance of secondary back-mixing and discharge of dust is increased
