Abstract
The invention relates to a helical tube panel roller slag cooler for a fluidized bed boiler. The slag cooler is provided with a cylindrical shell which is formed by coaxial welding of a cylindrical inner cylinder body and a cylindrical outer cylinder body, wherein a jacket space is formed between the inner cylinder body and the outer cylinder body; the bottom and one side of a cylinder body are provided with supporting and driving pedestals, supporting wheels, drive units and catch wheels; a water inlet, a water outlet, a slag inlet, a slag outlet device and a slag outlet are arranged at both ends of the cylinder body respectively; a helical tube panel is formed by bending a seamless steel tube; flat steel is taken as fins and welded with each other into a membrane-type tube panel which is coaxially welded on the inner wall of the inner cylinder body and between the helical tube panels; and vertical blades are uniformly arranged. Due to adoption of the helical tube panel instead of helical blades, the cooling efficiency of the slag cooler is greatly improved; due to large space in the cylinder body, people can conveniently enter the cylinder for overhaul from both ends; and simultaneously furnace slag is forcibly propelled, so that the phenomenon of clinker blockage cannot be generated.
Description
Technical field
The present invention relates to a kind of roller slag cooler that is used for fluidized-bed combustion boiler, is a kind of helical tube panel roller slag cooler specifically.
Background technology
Slag cooler is used for fluidized-bed combustion boiler, and to be slag that fluidized-bed combustion boiler is discharged be cooled to about 150 ℃ from about 900 ℃ in effect, reclaims heat, saves the energy, and cooled slag is convenient to mechanization and is carried and efflux simultaneously, saves the labour, improves production environment.
Present roller slag cooler, generally weld with one heart and form by inside and outside cylindrical shell, water flowing forms cooling jacket between the inside and outside cylindrical shell, the inner barrel interior welds has helical blade, promoting slag on the one hand advances, stretch fin as the court of a feudal ruler of cooling jacket on the one hand and participate in heat exchange, but will consider the effective heat transfer area of fin, the roller slag cooler volume of Bu Zhiing is very big like this.Also has a kind of multitube roller slag cooler in the prior art, in inner barrel inside some cooling water pipes are set, cylinder tilts to place, slag relies on deadweight to slide in cylindrical shell between each water pipe, the roller slag cooler cooling effectiveness of Bu Zhiing increases like this, but stifled easily slag, and break down and be difficult to maintenance in inside.
Summary of the invention
In order to overcome the existing existing technical problem of roller slag cooler, the invention provides a kind of helical tube panel roller slag cooler, this slag cooler can increase substantially cooling effectiveness, and is not easy stifled slag, breaks down and also is convenient to maintenance.
The technical solution adopted for the present invention to solve the technical problems is: this helical tube panel roller slag cooler mainly is made up of water inlet, delivery port, deslagging device, support roller, cylindrical shell, drive unit, shelves wheel, base, slag input device, slag inlet, slag notch, inner barrel, outer cylinder body, helical tube panel, longitudinal blade, seamless steel pipe and fin; It is characterized in that: this slag cooler has a cylindrical shell housing by inner barrel cylindraceous and outer cylinder body coaxial welding, is formed with the chuck space between the inside and outside cylindrical shell, and a cylindrical shell bottom and a side are provided with base, support roller, drive unit and the shelves wheel that supports and drive; The two ends of cylindrical shell are separately installed with water inlet, delivery port, slag inlet, deslagging device and slag notch, cooling water enters helical tube panel and chuck from water inlet, its cooling is discharged from delivery port, impel the slag cooling that enters from slag inlet,, discharge through deslagging device through the slag of supercooling from slag notch; Spiral helicine helical tube panel, bend by seamless steel pipe and to form, each other, be welded into film mode tube screen by band steel as fin, on the homoaxial inwall that is welded on inner barrel, can roll with cylindrical shell, the radical of this seamless steel pipe can be selected 1～8, in the present embodiment, the seamless steel pipe of two groups of helical tube panels is 4, and other two groups is 2, between adjacent helical tube panel, evenly distributed on circumference have a longitudinal blade, longitudinal blade tilts angle is arranged to the direction of rotation of cylindrical shell, is 20 °～45 °, in the present embodiment, cylindrical shell is rotated counterclockwise, and the inclination angle of longitudinal blade is 30 °.
The invention has the beneficial effects as follows: owing to adopt helical tube panel to substitute helical blade, increased substantially the cooling effectiveness of slag cooler, this be because: under the situation of same height, the heat exchange area of helical tube panel is much bigger; Helical tube panel is directly participated in heat exchange, and effective area is consistent with real area, and helical blade will be considered effective heat transfer area of fin, and general effective area has only about 50 percent of real area; Helical blade is at distance cooling water source temperature height at a distance, the heat exchange poor effect, and helical tube panel is all nearer apart from cooling water source everywhere.
Owing to adopted longitudinal blade to cylinder direction of rotation inclination certain angle, slag can be carried by longitudinal blade during the cylinder rotation, after surpassing the peak certain angle, just fall, slag contacts and heat exchange with inner tube wall and helical tube panel all the time in this process, has improved the cooling effectiveness of slag cooler.
Because helical tube panel and longitudinal blade all are to arrange along inner tube wall, the space is big in the tube, can enter maintenance in the tube easily from two ends; Because the space is big in the tube, slag is not by deadweight but forces to advance by spiral simultaneously, can not produce the clinker clogging.
