Description

Bag Dust Cleaner for Movable Bag Dust Collector

technical field

The utility model relates to a device for cleaning dust outside the bag surface of a bag filter.

Background technique

Douhe Power Plant of Datang International Power Generation Co., Ltd. changed the F365-4 type electrostatic precipitator of #3 unit to #8 unit from August 2012 to the FE type electric-bag composite precipitator. After the transformation, the original The five electric areas become an electric-bag composite dust collector with one electric area and four bag areas. The dust cleaning method of the electric area adopts the top electromagnetic vibration cleaning method, and the bag area adopts four sets of single row air box master pipes for centralized air supply The four air boxes in series are used to clean dust by blowing in series. With the prolongation of the operation time of the unit, the surface of the bags in the four bag areas has dust accumulation to varying degrees. After the dust accumulation, the pressure difference between the inlet and outlet of the bag area increases and the dust removal effect decreases. It will cause the host unit to be forced to reduce the load and affect the output of the unit. It is time-consuming and labor-intensive to carry out the original manual cleaning of the cloth bag, and the cloth bag is damaged, which prolongs the maintenance time.

Utility model content

In order to solve the problem of heavy dust cleaning workload and long time-consuming problem in the prior art, the utility model provides a bag dust collector, and the specific technical solution is:

A bag dust cleaner for a movable bag filter, including an air storage tank, a steam-water separator connected with the gas storage tank, a pressure regulating device connected with the steam-water separator, and a gas source pipe and an air extension pipe to communicate with the pressure The blowing head connected to the adjustment device, a pulse switch is installed at the position where the gas source pipeline and the air extension tube meet, and the blowing head is a hollow cylinder with air holes on the outer wall.

This utility model is suitable for bag cleaning of electric-bag composite dust collectors in thermal power plants, for cleaning the outer surface of bag dust collectors in steelmaking plants, and for cleaning dust and dust on the outside of bag dust collectors in cement manufacturing plants. Work, reduce the workload of maintenance personnel in the cleaning work, save unnecessary bag replacement costs, reduce unit costs, and increase the service life of the bag. Reduce dust emissions, improve sewage quality, and reduce workload during maintenance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

As shown in the figure, a bag dust cleaner of a movable bag filter includes an air storage tank 1, a steam-water separator 2 connected to the air storage tank 1, and a pressure regulating device 3 connected to the steam-water separator 2 , there is also a blowing head 7 connected to the pressure regulating device 3 through the gas source pipeline 4 and the gas extension pipe 6, and an electromagnetic pulse valve 5 is installed at the position where the gas source pipeline 4 and the gas extension pipe 5 are connected. The head 7 is a hollow cylinder with air holes on the outer wall.

The working principle of the utility model is to use an external air source pipe to inflate the air storage tank 1, then filter the moisture through the steam-water separator 2, and then go to the pressure regulating device 3, and control the start and stop of the ash cleaner through the manual operation of the electromagnetic pulse valve 5 state.

When the utility model is in use, it is placed outside the clean flue, the air extension pipe 6 is introduced into the ash cleaning chamber, and the blowing head 7 is inserted into the bag cavity to spray and clean the bag. The blowing head 7 may be closed at the bottom, and an air outlet with a diameter of about 10 mm is provided on the column wall. The air outlet sprays out high-pressure air to clean the dust on the outer wall of the bag. When cleaning the dust, the range of movement of the spray head is limited to the length of the air pipe, and the dust at different positions of the bag can be cleaned at any position within the length of the air pipe.

In order to prevent damage to the cloth bag during the dust cleaning process, the dust remover of the utility model can be provided with a plurality of branch hoses downstream of the air duct, and simultaneously enter the cloth bag, and spray and clean the cloth bag in a dispersed manner.

The utility model is used for bag cleaning of electric-bag composite dust collectors in thermal power plants, and bag cleaning of bag dust collector equipment in other industries. The equipment is easy to operate and flexible. Using this equipment can improve the air permeability of the bag, reduce the pressure difference in the bag area, prevent the bag from being damaged due to a large pressure difference, prolong the service life of the bag, save costs, and prevent the main unit from being damaged due to a large pressure difference between the inlet and outlet of the bag. Reduce the load, improve the quality of sewage discharge, and reduce the workload during maintenance.
