Description

Ash cleaning system for preventing ash storehouse from being hung on wall

Technical Field

The utility model relates to a purify dust removal technical field, concretely relates to ash storehouse prevents hanging wall deashing system. The ash removal system can effectively reduce and avoid dust hanging on walls and hardening on the walls of equipment such as an ash warehouse and a storage bin, reduces regular warehouse cleaning work, and avoids dust collapse.

Background

An ash storehouse or a storage bin is the tail end of an ash removal system, is a common facility for storing and collecting dust materials at present, and is widely used in industries such as coal-fired power plants, steel, cement, chemical engineering and the like. As shown in fig. 1, a bag-type dust collector is disposed on the top of the ash silo, so that the interior of the ash silo communicates with the atmosphere outside the ash silo, and the dust in the ash silo cannot overflow due to the filtering and blocking of the bag in the ash silo. The side of the ash storehouse is provided with a feed inlet, and positive pressure air flow wrapped dust enters the ash storehouse from the feed inlet. The lower part of the ash storehouse is usually designed to be a cone-shaped ash bucket, a discharge valve is arranged below the ash bucket, and when the discharge valve is opened, the dust in the ash storehouse can be discharged.

In use, powder materials are generally blown into the ash storehouse through positive pressure, the powder materials are in a dust raising state when entering the ash storehouse, most of the materials naturally deposit downwards due to the action of gravity after entering the ash storehouse and are gathered in the conical ash hopper at the lower part of the ash storehouse, when ash is discharged, a discharge valve below the ash hopper is opened, and dust is discharged from the ash storehouse through the discharge valve.

However, when dust enters the dust silo along with the airflow, the dust with a small particle size is difficult to deposit because of long dead time, and may adhere to the inner wall around the dust silo. Along with the prolonging of the service time, the dust layer attached to the inner wall of the ash storehouse becomes thick, and the phenomena of mutual hardening and blocking appear. Slump and flaking may occur when driven by vibration or other factors. At this time, the falling ash block may block the ash discharge port below the ash silo, resulting in unsmooth ash conveying of the ash silo. Affecting the continuous production of the system.

In addition, the ash bin dust wall builds up and agglomerates, resulting in the necessity of periodic ash bin cleaning. The dust collapse phenomenon can also bring potential safety hazards to the warehouse cleaning work.
