Abstract
The utility model discloses a chemical engineering three-waste waste heat boiler, which includes an ash bucket and a heat-insulating tunnel built thereon, wherein a steel frame is connected onto the ash bucket; a boiler barrel is installed at the top of the steel frame; a slag condensation pipe clamp, an overheater, convection pipe clamps, an economizer and an air preheater are sequentially arranged in the heat-insulating tunnel in the flue gas flowing direction; all the convection pipe clamps are formed by heat exchange pipe units; and furnace doors are arranged among the convection pipe clamps. The chemical engineering three-waste waste heat boiler has convenience for maintenance, installation and transportation as well as high circulation efficiency.
Description
Technical field
The utility model relates to a kind of tunnel type waste heat boiler, relates in particular to a kind of chemical industry three wastes waste heat boiler.
Background technology
Problems such as general tunnel type chemical industry three wastes waste heat boiler all exists the convection bank pipe pitch that causes owing to the heating surface area needs little, and the economizer structure is huge, thus cause welding quality to be difficult to guarantee; Finally cause leaking, and because convection bank is arranged overstockedly, 8 groups even 10 groups of convection banks are arranged together; Can make pipe in a single day leak and just be difficult to maintenance, cause economic loss, for whole system; After drum is arranged and is leaned on; Cause the interior water-cooled part of stove and the closed circuit between the drum of the place ahead incinerator long, the water-cooled part leaks in the stove because of circulation does not freely make easily, causes safety problem and economic loss.
The utility model content
The purpose of the utility model provides a kind of maintenance chemical industry three wastes waste heat boiler easily.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of chemical industry three wastes waste heat boiler; Comprise ash dropping hopper and build insulation tunnel above that; Be connected with steelframe on the ash dropping hopper, the steelframe top is equipped with drum, in the insulation tunnel, is disposed with Crust blocks pipe bundle, superheater, convection bank, economizer and air preheater along the flow of flue gas direction; Convection bank is formed by multi-disc heat exchanger tube unit, is provided with fire door between said per two groups of convection banks.
Be equipped with fin on the heat exchanger tube of said convection bank, fin is provided with along the flow of flue gas direction.
Said drum is arranged at the rear portion of superheater and the front portion of convection bank.
Said economizer is the membrane type economizer, and the economizer pipe is that coiled pipe and pipe both sides are equipped with fin.
The advantage of the utility model is: 1, establish a fire door between per 2 groups of the convection bank, 2 groups of convection banks about each fire door is corresponding, very convenient maintenance; 2, convection bank adopts the mode of extended surface tube to increase heat exchange area, therefore can adopt less convection bank group number, bigger pipe transverse pitch, reduces the welding difficulty, thereby has guaranteed welding quality; 3, economizer adopts the membrane type economizer, and sound construction has increased the wearability of pipe, has saved material, and be convenient to install, transportation; 4, drum is arranged in the waste heat boiler anterior position, has shortened the steam guiding tube of combustion furnace water-cooled part and the length of down-comer, has improved cycle efficieny, has reduced the potential safety hazard of freely not bringing because of circulation.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is one group of convection bank structural representation in the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of chemical industry three wastes waste heat boiler comprises ash dropping hopper 6 and builds insulation tunnel 2 above that; Be connected with steelframe 1 on the ash dropping hopper 6, steelframe 1 top is equipped with drum 9, in insulation tunnel 2, is disposed with Crust blocks pipe bundle 3, high temperature superheater 42, low temperature superheater 41, convection bank 5, economizer 7 and air preheater 8 along the flow of flue gas direction; Convection bank 5 is formed by multi-disc heat exchanger tube Unit 51; Be equipped with fin 52 on the heat exchanger tube 51 of convection bank 5, fin 52 is provided with along the flow of flue gas direction, and the extended surface tube structure is adopted in convection bank 5; Greatly improved heating surface area and heat transfer efficiency, simple and compact for structure; Be equipped with fire door 10 between per two groups of convection banks 5,2 groups of convection banks 5 about each fire door is corresponding, very convenient maintenance; Said drum 9 is arranged at low temperature superheater 41 rear portions, and drum 9 is preposition, has shortened the steam guiding tube of combustion furnace water-cooled part and the length of down-comer, has improved cycle efficieny, has reduced the potential safety hazard of freely not bringing because of circulation; Said economizer 7 is the membrane type economizer, and the pipe of economizer 7 is that coiled pipe and pipe both sides are equipped with fin.
During the utility model work; Flue gas gets into the back through high temperature superheater 42, low temperature superheater 41 from the mouth that advances of Crust blocks pipe bundle 3 front ends; Through convection bank, flying dust is because inertia falls into ash dropping hopper 6 bottoms then, and flue gas gets into economizer 7 and air preheater 8 subsequently; After water got into from economizer 7, entering drum 9 got into circulation in convection bank 5 and the crust block pipe 3 after drum 9 inner carbonated drinks are separated, and got into overheated back supply user in high temperature superheater 42, the low temperature superheater 41 then.
