A dry ash loading device for coal-fired power plants

Abstract

The invention discloses a dry ash loading device for a coal-fired power plant. Several ash hoppers are arranged in the ash storage, and a manual gate valve is arranged at the ash outlet at the bottom of the ash hopper. The ash pipe is connected in turn with a pneumatic gate valve and an expansion joint. The outlet end of the expansion joint is connected to the ash inlet of the dry ash bulk machine through a manual butterfly valve. A bulk head is provided at the ash outlet of the dry ash bulk machine; There is a bag dust collector at the ash outlet, the air suction port of the bag dust collector faces the ash outlet of the dry ash bulk machine, the air outlet of the bag dust collector is connected to a dust extraction fan, and the inclination angle of the ash fall pipe is set. The equipment of the present invention is simple, and by arranging the inclination angle of the ash-falling pipe, manual butterfly valve, and bag filter, the wear problem of the dust extraction fan is solved, the falling speed of the material is reduced, the flying of the material is reduced, and the environmental pollution problem during loading is solved. , Improve the loading environment, reduce the investment cost, operation and maintenance amount and the risk of pipe blockage.

Description

technical field

[0001] The invention relates to a dry ash loading device for coal-fired power plants, which is suitable for coal-fired plants, cement, chemical industry, metallurgy and other industries, and belongs to the technical field of factory conveying equipment. Background technique

[0002] The dry ash loading device is often used in coal-fired power plants. Because coal-fired power plants generate a large amount of dry ash during operation, based on the consideration of environmental protection and reuse, it is necessary to transport the dry ash to the ash brick factory or other users. When transporting When the distance is long or the end user is not sure, the way of transporting the dry ash stored in the ash warehouse is to be delivered to the end user by a sealed tank truck. The purpose of the dry ash loading device is to smoothly load the dry ash in the ash silo into the sealed car under the ash silo, and ensure the loading process is smooth without jamming, dus...
