Problems solved by technology

[0002] The existing cylindrical inner and outer walls of the slag cooler are supported by steel bars spirally wound on the inner wall, so that a cooling water interlayer is formed between the two walls. Since the cooling water is limited by the steel bars, it can only flow along the spiral Channel flow, the flow rate of water is slow and the flow rate is small, which cannot meet the needs of slag cooling. The temperature of the slag entering from the slag inlet is 1100-1200°C, and the temperature of the slag coming out of the slag outlet of the slag cooler is as high as 350-400°C. It needs natural cooling before it can be loaded and transported away, which pollutes the environment; and because of the slow flow rate of cooling water, the water is often vaporized before reaching the slag inlet of the slag cooler, causing the inner wall of the slag cooler to be burned out, affecting the normal production

Abstract

The invention relates to a slag cooler for cooling slag of a circulating fluidized bed boiler of a power plant, mainly designed to solve the problems of poor cooling effect and easy burnout of the traditional slag cooler. The slag cooler comprises an inner cylinder wall, an outer cylinder wall, a cooling water interlayer, a slag guide sheet, a slag inlet, a slag outlet end, a track, a track supporting wheel, a large sprocket, a water inlet pump and a water pumping pump, wherein a partition wall is arranged between the inner cylinder wall and the outer cylinder wall, a small support upright column is respectively arranged between the partition wall and the inner cylinder wall as well as between the partition wall and the outer cylinder wall, an inner sealing head and an outer sealing head are also arranged between the partition wall and the inner cylinder wall as well as between the partition wall and the outer cylinder wall, a pipeline is arranged on the water inlet pump and is connected with an inner ring of a water separator, the inner ring is provided with a water outlet and is connected with an outer ring in a sliding and sealing mode, a water outlet pipe is arranged on the outer ring and is connected with the inner sealing head, a pipeline is arranged on the water pumping pump and is connected with an inner ring of a water collector, a water inlet is arranged on the inner ring of the water collector, the external of the inner ring of the water collector is connected with the outer ring of the water collector in the sliding and sealing mode, and a water inlet pipe is arranged on the outer ring and is connected with the outer sealing head. The invention has the advantages of good cooling effect and long service life.

Description

Technical field: [0001] The invention relates to a slag cooler for cooling the slag of a circulating fluidized bed boiler in a power plant. Background technique: [0002] The existing cylindrical inner and outer walls of the slag cooler are supported by steel bars spirally wound on the inner wall, so that a cooling water interlayer is formed between the two walls. Since the cooling water is limited by the steel bars, it can only flow along the spiral The channel flows, the flow rate of water is slow and the flow rate is small, which cannot meet the needs of slag cooling. The temperature of the slag entering from the slag inlet is 1100-1200°C, and the temperature of the slag coming out of the slag outlet of the slag cooler is as high as 350-400°C. It needs natural cooling before it can be loaded and transported away, polluting the environment; moreover, due to the slow flow of cooling water, the water is often vaporized before reaching the slag inlet of the slag cooler, causi...
