Description

Bag-type dust collector

Technical Field

The utility model belongs to the technical field of the dust remover, concretely relates to sack cleaner.

Background

At present, a heavy ash process bag-type dust collector is a main device for ensuring stable production of heavy ash, can ensure that heavy ash tail gas reaches the standard and is discharged, and effectively recovers alkaline dust in the tail gas. However, as the service life of the bag-type dust collector is prolonged, the efficiency of the bag-type dust collector is reduced, the shell is washed, corroded and damaged, a part of bag is hardened and locked, the fluidized bed is pressurized, the pipeline is blocked, and bag ash buckets are frequently blocked.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows: to the technical problem, the utility model provides a sack cleaner can effectively retrieve the alkali dust in the tail gas, prolongs the life of equipment, guarantees that tail gas emission to reach standard reduces the running cost.

The technical scheme is as follows: the utility model provides a bag-type dust collector, includes box, filter bag, gas bag, ash bucket, unloading spiral, unloading star type and PCL controller, set up a plurality of filter bags in the box, the open end and the gas bag of filter bag are connected through jetting pipe, be equipped with the electromagnetic pulse valve on the jetting pipe, the electromagnetic pulse valve is connected with the PLC controller, the ash bucket sets up the bottom at the box, the bottom discharge gate and the feed inlet of unloading spiral of ash bucket are connected, the discharge gate of unloading spiral is connected with the feed inlet of unloading star type, the lateral wall of ash bucket is equipped with the air inlet, the lateral wall of box is equipped with the gas outlet.

Preferably, an airflow diagnosis device is arranged on the blowing pipe.

Preferably, a vibrator is arranged on the inner wall of the ash bucket.

Preferably, the filter bag is a high-temperature-resistant and acid-alkali-resistant cloth bag.

Preferably, keels are arranged in the filter bags.

Further, the keel is arranged in the box body through a support.

Has the advantages that: the bag-type dust collector can effectively recycle the alkali dust in the tail gas, thereby increasing the economic benefit; caking on the ash hopper wall of the bag-type dust collector is effectively prevented, and the generation of falling products is reduced; the service life of the filter bag of the bag-type dust collector is prolonged, and the operation cost is reduced; ensuring that the tail gas of the heavy ash system is discharged up to the standard; the workload of field workers for cleaning the accumulated alkali blockage is reduced, and the working strength of field operators is reduced; through increase of service life, the failure rate is reduced, and the labor cost for equipment maintenance is reduced.

Drawings

FIG. 1 is a schematic view of the present invention;

sequence numbers in the figure: 1. the device comprises a box body, 2, filter bags, 3, an air outlet, 4, an air bag, 5, an airflow diagnostor, 6, a dust hopper, 7, an air inlet, 8, a vibrator, 9, a feeding star, 10, a feeding spiral, 11 and a PLC.

Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1, a bag-type dust collector, includes box 1, filter bag 2, air bag 4, ash bucket 6, unloading spiral 10, unloading star type 9 and PCL controller 11, set up a plurality of filter bags 2 in the box 1, filter bag 2 is high temperature resistant acid and alkali-resistant sack, be equipped with fossil fragments in the filter bag 2, fossil fragments pass through the support setting in box 1, the open end and the air bag 4 of filter bag 2 are connected through the injection pipe, be equipped with electromagnetic pulse valve and air current diagnotor 5 on the injection pipe, the electromagnetic pulse valve is connected with PLC controller 11, ash bucket 6 sets up the bottom at box 1, be equipped with vibrator 8 on the inner wall of ash bucket 6, the bottom discharge gate of ash bucket 6 is connected with the feed inlet of unloading spiral 10, the discharge gate of unloading spiral 10 is connected with the feed inlet of unloading star type 9, the lateral wall of ash bucket 6 is equipped with air inlet 7, the lateral wall of box 1 is equipped with gas outlet 3.

Tail gas passes through air inlet 7 and gets into ash bucket 6, relies on gravity to subside partial dust, then gets into box 1, carries out the secondary through filter bag 2 and removes dust, and the gas after the dust removal is discharged to the atmosphere through gas outlet 3, and the dust of production is collected through unloading spiral 10, then retrieves through unloading star type 9. The vibrator 8 is vibrated at regular time to prevent dust from being settled, and the airflow diagnostor 5 judges whether each ejection pipe ejects gas normally or not to ensure that the gas bag 4 works normally. A large amount of clean compressed air is constantly stored in the air bag 4, electromagnetic pulse is performed at regular time according to the setting of the PLC 11, and the clean compressed air is sprayed by the electromagnetic pulse to drop the alkali dust on the filter bag 2 to the dust hopper 6.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
