Abstract

The utility model relates to a cylinder type device for removing ash which is composed of a removing ash device, a flange, an outer shell, water pipes, an inspection hole, etc. The two water pipes provided with a nozzle are arranged at the inner wall of the cylinder of the removing ash device along the tangential direction. Ash is removed by the swirling flow formed beside water. The cylinder type device for removing ash is mainly used for hydraulic removing ash systems of industrial boilers. The coal ash which is obtained after high-temperature combustion passes through a coal economizer and an air preheater, the dust of the coal ash is removed by an electric precipitator, the coal ash falls into an ash bucket and enters the device for removing ash through a falling ash pipe, and the coal ash is flushed into a trench by water. The utility model has the advantages of reasonable design, simple structure, small volume, material saving, good sealing performance of water sealing, little water consumption for removing ash, long service life, etc. Ash can be easily removed and is not easily deposited.

Description

Cylinder type device for removing ash

The utility model belongs to a kind of garden cartridge type tube blower.

At present, coastal large-size thermal power plant ash discharge amount is big, now adopts box tube blower, big towards grey water consumption, but the coastal area freshwater resources lack, generally in the design consider to adopt seawater to dash ash, and seawater can produce heavy corrosion to general iron and steel, so the life-span of general tube blower is not long.

The purpose of this utility model is the water pipe that tangential direction is adorned two band nozzles on tube limit, tube blower garden, utilizes waterpower to dash ash, and it is big to overcome existing box tube blower water consumption, and shortcomings such as capacity dust stratification improve power plant's property safe and reliable to operation and economy.

The utility model is by tube blower, flange, shell, water pipe, compositions such as inspection opening, be with bell-mouthed ash charge mouth (2) to be fastened on the garden tube shell (6), ash charge mouth (2) is equipped with connecting flange (1), the available screw of connecting flange (1) is fastened on the ash tube, cylindrical shape tube blower (3) leaves certain interval with shell, be fixed on shell (6) inwall, be contained in below the ash charge mouth (2), article two, the oral siphon (4) that has a nozzle just, stagger relatively and pass shell (6), be fastened on the tangential direction at tube blower (3) edge, shell (6) bottom is funnel type, and grey water out (5) is arranged, but the ground connection ditch, shell (6) upper end has inspection opening (7), so that operation is observed.

Advantages such as the utility model is reasonable in design, and is simple in structure, and it is little to have a volume, and materials are few, and the water seal tightness is good, and is few towards grey water consumption, is not easy dust stratification, and it is smooth to dash ash, and the life-span is long.

Description of drawings:

Fig. 1 is the utility model structure chart;

Fig. 2 is the utility model vertical view.

The utility model preferably selects for use not only seawater corrosion resistance but also anti abrasive metal material to make, also can select the abrasion-resistant stee manufacturing, be mainly used in the Industrial Boiler ash trench system, can be with the coal ash behind the high-temp combustion through economizer, air preheater, after the electric cleaner dedusting, fall into ash bucket enters the drum type brake tube blower through ash tube ash charge mouth (2), enter differing heights place, circular tube blower (3) tube blower (3) bottom again and adorning the oral siphon (4) that has nozzle, when water when tangentially entering tube blower (3) by oral siphon (4), one in the face of an ash stirring action, another side makes buck overflow through grey water out (5) from cylindrical shape tube blower (3) upper edge and enters trench, when stopping ash discharge, because the water surface of tube blower (3) exceeds certain height than ash charge mouth (2) lower edge, form water seal, can prevent that air from entering boiler and deduster.The utility model water seal tightness is good, and ash charge mouth (2) band horn mouth is not easy dust stratification, and it is smooth to dash ash, is fit to various places power plant and uses, and can prolong the service life of tube blower so greatly, improves power plant's property safe and reliable to operation and economy.

Claims

1, a kind of drum type brake tube blower, form by tube blower, flange, shell, water pipe inspection opening etc., it is characterized in that: be with flaring ash charge mouth (2) to be fastened on the barrel shrond (6), connecting flange (1) is housed on the ash charge mouth (2), the available screw of connecting flange (1) is fastened on the ash tube, and cylindrical shape tube blower (3) leaves certain interval with shell, is fixed on the outer casing inner wall, its upper edge exceeds ash charge mouth lower end certain altitude, to form good water seal.Article two, the oral siphon (4) that has a nozzle just staggers relatively and passes shell (6), and nozzle is fastened on the tangential direction of tube blower (3) inwall, and shell (6) bottom is funnel type, and grey water out (5) is arranged, but the ground connection pond.Shell (6) upper end has peep hole (7).
