Description
Technical field
The utility model relates to a kind of ash bucket, especially for the light-duty membrane wall water-cooled ash bucket of waste heat boiler.
Background technology
The ash bucket of Natural Circulation HRSG in the past is comprised of steel plate and built-in insulation material and refractory concrete mostly, when the ash that falls is smooth, do not need the steel plate of percussion vibration ash bucket to make it to discharge the deposition lime-ash, but built-in refractory material is after vibration is beaten, and can cause breaks comes off, and loses heat insulation function; Because the temperature of radiation and high temperature ash is higher general carbon steel sheet is damaged the ash bucket of high-temperature area, the physics sensible heat that the high-temperature ash of discharging is in addition taken away is a kind of thermal loss, discharge high warm ash and produce thermal pollution, waste heat boiler all is continuous operation usually, and long-term accumulative total is a kind of wasting of resources; For the ease of transportation, the hot lime-ash of discharge also need add water for cooling, produces excitant water smoke, and environment was both polluted, and had wasted again water resource; Often adopt two side walls and the ash bucket diminishing water-cooled ash bucket in bottom that is connected in the nonferrous smelting waste heat boiler, but this structure needs be used in conjunction with continuous scraper plate, its manufacturing expense is large, difficulty is high, Heavy Weight, expense are high.
The utility model content
The purpose of this utility model is for the prior art above shortcomings, and a kind of light-duty membrane wall water-cooled ash bucket is provided, and it has advantages of that manufacture difficulty is little, lightweight, cost is low and be energy-conservation, and environmental contamination reduction.
For achieving the above object, light-duty membrane wall water-cooled ash bucket of the present utility model, comprise the infundibulate ash bucket that several sidewalls form, it is characterized in that every sidewall includes inboard fin panel casing and the heat-insulation layer of being located at the pattern water-cooling wall outside, described fin panel casing includes the horizontal header on top, the inverted trapezoidal header of bottom, the several L-type water screen tubes that connect horizontal header and inverted trapezoidal header, and the sealing band steel that connects adjacent two water screen tubes, be provided with water inlet pipe in inverted trapezoidal header, be provided with the carbonated drink tube connector in horizontal header, all be fixedly connected with steel plate in the upper end of horizontal header and the lower end of two ends and inverted trapezoidal header, the steel plate of both sides connects firmly on the adjacent two side.
During use, water inlet pipe is linked to each other with the common downcomer of boiler, the carbonated drink tube connector links to each other with drum, every fin panel casing all can form water circulation, to cool off the lime-ash heat absorption and to flash to the purpose that steam reaches energy-conservation, improves the thermal efficiency, and environmental contamination reduction, and need not to be used in conjunction with continuous scraper plate, have advantages of that manufacture difficulty is little, lightweight, cost is low;
As further improvement of the utility model, be provided with ash-valve in the lower end of infundibulate ash bucket; Ash-valve can the ash discharge function can be locked gas again, and inner flue gas of the stove and atmosphere are isolated from each other, and further improves the thermal efficiency and environmental contamination reduction;
As further improvement of the utility model, two upper head plates of inverted trapezoidal header are restricting orifice, and they all link to each other with horizontal header by water screen tube; Can improve the intensity of fin panel casing, can further improve again the thermal efficiency;
In sum, the utlity model has the advantage that manufacture difficulty is little, lightweight, cost is low and energy-conservation, and environmental contamination reduction.
