Description

A chimney dust removal device

technical field

The utility model belongs to the technical field of electrostatic dust removal, and relates to an electrostatic dust removal device, in particular to a chimney dust removal device.

Background technique

The electrostatic precipitator is a device that charges the dust particles during the ionization process of the dust-containing gas through a high-voltage electric field, and deposits the dust particles in the dust collector under the action of the electric field force to separate the dust particles from the dust-containing gas. A dust removal device. At present, my country's environmental situation is severe, especially the air pollution is very serious, and the air PM2.5 seriously exceeds the standard. Therefore, energy conservation and emission reduction have become the top priority of major enterprises. In particular, coal-fired thermal power plants, thermal power plants, and steel plants should pay more attention to the issue of energy saving and emission reduction. Therefore, a device that can effectively reduce the content of dust particles in the flue gas is needed to make the emission of flue gas meet the national standards.

Contents of the invention

The purpose of this utility model is to provide a chimney dedusting device, which is novel in design, easy to install in the chimney, and can ensure that the emission of flue gas is not affected to the greatest extent, effectively removes dust particles in the chimney, and has a very high use value.

The purpose of this utility model is achieved in this way: a chimney dust removal device, including a shell, an insulating net, an electrode, a dust collecting hopper, a sliding dust pipe, and a dust collecting bin, the shell is fixed inside the chimney, and the An insulating net is fixed on the upper part of the housing, electrodes are installed on the insulating net, and a dust collecting bucket is fixed on the lower part of the housing, and the dust collecting bucket is connected to the dust collecting bin through a sliding dust pipe.

The shell is umbrella-shaped and has a circular opening on the upper part.

Both the insulating net and the dust collecting hopper are fixed to the casing by rod welding.

Many small holes are evenly distributed on the insulating net, and the electrodes are fixed on the insulating net through insulators.

The dust collection bin is located outside the chimney, and the dust sliding pipe on the upper part of the dust collection bin runs through the chimney.

The chimney dedusting device can be set as one or two.

The beneficial effects produced by the utility model are: a chimney dedusting device, the shell is fixedly installed on the chimney, the shell is designed as an umbrella, and a circular hole is opened on the upper part, and the insulation net is designed to have many small holes on it In the form of each, we try our best to ensure that the emission of flue gas will not be affected. When the flue gas passes through the electrodes, under the action of the high-voltage electrostatic field between the electrodes, the gas molecules are ionized to form positive ions and electrons, and the electrons encounter dust particles when moving to the positive electrode, making the dust particles negatively charged and adsorbed to the positive electrode, and then It falls into the dust hopper and is collected to remove the dust particles in the flue gas.

detailed description

Embodiments of the utility model are further described below in conjunction with the accompanying drawings.

Example 1

As shown in the accompanying drawings 1-2, a chimney dust removal device includes a housing 2, an insulating net 3, an electrode 4, a dust collecting bucket 5, a sliding dust pipe 6, and a dust collecting bin 7, and the housing 2 is fixed on the chimney. 1, the upper part of the housing 2 is fixed with an insulating net 3, the electrode 4 is installed on the insulating net 3, and the lower part of the housing 2 is fixed with a dust collecting bucket 5, and the dust collecting bucket 5 passes through The sliding dust pipe 6 is connected with the dust collecting bin 7 .

The housing 2 is umbrella-shaped and has a circular opening on the top.

Both the insulating net 3 and the dust collecting bucket 5 are fixed to the casing 2 by welding the rods 8 .

The insulating net 3 is evenly distributed with many small holes, and the electrodes 4 are fixed on the insulating net 3 through insulators.

The dust collection bin 7 is located outside the chimney 1 , and the dust sliding pipe 6 on the upper part of the dust collection bin 7 runs through the chimney 1 .

The chimney dedusting device can be set as one or two.

When the utility model is in use: the shell is fixed inside the chimney, the insulating net and the dust collecting hopper are fixed on the shell by rod welding, and the electrodes are fixed on the insulating net through insulators. Under the action of the high-voltage electrostatic field, the gas molecules are ionized to form positive ions and electrons. When the electrons move towards the positive pole, they encounter dust particles, which make the dust particles negatively charged and adsorbed to the positive pole. After that, the dust particles fall into the dust hopper below. Then, the dust particles in the dust collection hopper flow into the dust collection bin outside the chimney through the sliding dust pipe. If the installation of a dust removal device cannot meet the national gas emission standards, an additional dust removal device can be installed to achieve the purpose of flue gas dust removal .

In general, the utility model has a novel design, a simple structure, is convenient for retrofitting and installing in the chimney, and can effectively reduce the dust content in the flue gas.
