Efficient cloth bag dust removal automatic flushing device and flushing and drying method

Abstract

The invention belongs to an efficient cloth bag dust removal automatic flushing device and a flushing and drying method. The device comprises a cloth bag dust removal box, a plurality of dust removalcloth bags in the cloth bag dust removal box are divided into a plurality of rows to be arranged on the upper portion in the cloth bag dust removal box, and the bottom of each row of dust removal cloth bags is correspondingly provided with a group of automatic walking, flushing drying units; each automatic walking, flushing and drying unit comprises a horizontal walking part, a vertical walking part and a flushing and drying part; flushing nozzles in the flushing and drying parts are connected with a first tee joint through hoses with control valves, and the second end of the first tee joint is connected with a cloth bag flushing water tank through a water pipe stop valve and an automatic flushing water pump in sequence; the third end of the first tee joint is connected with a water returnport of the cloth bag flushing water tank through a second tee joint and a flushing water return valve; the third end of the second tee joint is connected with an air drying fan through an air pipe stop valve and a shell pass of an air heat exchanger. The cloth efficient cloth bag dust removal automatic flushing device has the advantages that the operation is stable, the service life of the clothbags in the cloth bag-type dust collector is prolonged, and the normal operation of the device is prevented from being influenced by cloth bag replacement.

Description

Technical field [0001] The invention belongs to the technical field of auxiliary components for compound fertilizer production, and specifically relates to a high-efficiency cloth bag dust removal automatic washing device and a washing and drying method. Background technique [0002] Bag dust removal is a technology that is widely used in the field of dust recovery. It mainly uses bag filter elements to fully filter the dust and particles in the air. As the filtering time increases, dust gradually accumulates in the bag. The conventional method Pulse blowing backwashing device is used to wash cloth bags. Pulse blowing backwashing has a good cleaning effect on dust removal locations with low ash and water content, but for dust with large water content and easy adhesion, such as compound fertilizer production In the process of bag-type dust removal, although bag-type dust removal guarantees the dust removal effect of the process production, due to the nature of the material, the co...

Problems solved by technology

[0002] Bag dust removal is a technology that is widely used in the field of dust recovery. It mainly uses bag filter elements to fully filter dust and particles in the air. As the filtration time increases, dust gradually accumulates in the bag. Conventional methods The pulse blowing backwashing device is used to flush the cloth bag. The pulse blowing backwashing has a better cleaning effect on the dust removal site with low ash and water content, but it has a large water content and is easy to stick to the bag dust removal, such as compound fertilizer production. In the process of bag dust removal, although the bag dust removal can ensure the dust removal effect of the process, due to the nature of the material, the compound fertilizer dust particles are bonded to the bag, and the bonded dust cannot fall off even under the pulse back blowing. The resistance of the bonded bag increases significantly, which significantly increases the power consumption in the overall dust removal process, and in severe cases, the product does not meet the standard or the device is shut down

At present, in actual production, the dust removal effect is guaranteed by regularly replacing the cloth bag. The general service life is 5-7 months, which is far lower than the 36-40 month service life of conventional cloth bags.
