Abstract
The utility model discloses a kind of tunnel cave membrane wall structure waste heat steam boiler, single drum is arranged along tunnel kiln longitudinal, in tunnel kiln, between both sides, be provided with row's membrane wall tube bank, membrane wall tube bank is constant slope lateral arrangement at Yao Ding, the two ends of membrane wall tube bank are connected with left and right header respectively, left header is connected with drum by down-comer, and right header is connected with drum by steam-water mixing pipe.The utility model is saved the energy, the thermal efficiency is high, operating cost is low.
Description
Technical field
The utility model relates to a kind of boiler plant, especially relates to a kind of tunnel cave membrane wall structure waste heat steam boiler.
Background technology
Coal gangue baked brick is to take the useless quarrel in colliery (spoil) to form as raw material sintering, be widely used in office building, the building such as house owed by a citizen, enclosure wall, the body of wall load-bearing New Building Materials of instead of clay brick, there is resistance to compression, anti-folding, weathering resistance, anticorrosive, acid and alkali-resistance, good heat insulating, speed of application is fast, saves the advantages such as sand, slurry.Its line of production technology is this head " eating " gangue, and that sintering oven is " spuing " red as fire fragment of brick regularly, allows coal shale in brick making " oneself burns oneself ".In the dry temperature-fall period of postmedian brick of this production line, its kiln top temperature is greatly about 900 ℃ of left and right, and this part heat energy all wastes at ordinary times.
Summary of the invention
The purpose of this utility model is: a kind of energy, the thermal efficiency is high, operating cost is low tunnel cave membrane wall structure waste heat steam boiler saved is provided.
The technical solution of the utility model is: a kind of tunnel cave membrane wall structure waste heat steam boiler, comprise tunnel kiln, single drum, single drum is arranged along tunnel kiln longitudinal, in tunnel kiln, between both sides, be provided with row's membrane wall tube bank, membrane wall tube bank adopts the pipe of keeping straight on to arrange, membrane wall tube bank is constant slope lateral arrangement at Yao Ding, membrane wall tube bank below arranges coal gangue baked brick, the two ends of membrane wall tube bank are connected with left and right header respectively, left header is connected with drum by down-comer, right header is connected with drum by steam-water mixing pipe, down-comer and steam-water mixing pipe are arranged on tunnel kiln outside, drum is connected with softening water pipe.
Further, the angle of inclination of membrane wall tube bank is 10-18 °.
The beneficial effects of the utility model are: because heating surface adopts membrane wall tube bank, adopt full-closed structure, can accept radiant heat completely, the coefficient of heat transfer is high, makes this boiler have more than 10% overload capacity; Because adopting membrane wall structure, strong from deashing ability, be difficult for dust stratification, make boiler there is the higher thermal efficiency, boiler operatiopn expense is low, and novel structure is compact.Boiler down-comer is arranged on kiln outside and is not heated, and has guaranteed rational rate of circulating flow; Water circulation system is reasonable in design, and boiler tube is less scaling, and boiler operatiopn is safe and reliable.Evaporation capacity of the present utility model is 3.0t/h, compares with the combustion II class bituminous coal with exerting oneself, and within 1 year, by ten months 7200 hours, calculates, one 3740 tons, Spring Festival holidays II class bituminous coal, by 800 yuan/ton, market price bituminous coal, can save 299.2 ten thousand yuan of RMB, and CO that can about 4,200,000 m3 of every young discharge
2, be conducive to environmental protection and reduce greenhouse effects, there is good economic and social benefit.The utility model applicable to chemical industry heating, wash dye, pharmacy, production of construction materials, food production etc., the fire coal of alternative enterprises or the steam boiler of fuel vapor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
From structural representation of the present utility model shown in Fig. 1, can find out, the utility model comprises the parts such as tunnel kiln 6, single drum 5, membrane wall tube bank 3, left header 1, right header 7, down-comer 2, steam-water mixing pipe 8.Single drum 5 is arranged along tunnel kiln 6 longitudinals, between the interior both sides of tunnel kiln 6, be provided with row's membrane wall tube bank 3, membrane wall tube bank 3 adopts the pipe of keeping straight on to arrange, and membrane wall tube bank 3 is constant slope lateral arrangement at Yao Ding, be advisable with 10-18 ° in the angle of inclination of membrane wall tube bank 3, left low right height.Membrane wall is restrained 3 belows coal gangue baked brick 4 is set, and heating surface adopts membrane wall tube bank, adopts full-closed structure, can accept radiant heat completely.The two ends of membrane wall tube bank 3 are connected with left and right header respectively, left header 1 is connected with drum 5 by down-comer 2, right header 7 is connected with drum 5 by steam-water mixing pipe 8, and down-comer 2 and steam-water mixing pipe 8 are arranged on tunnel kiln 6 outsides, and drum 5 is connected with softening water pipe 9.According to the production technology of coal gangue baked brick, heating surface area is calculated and done reasonable adjustment according to heating power, according to the heat transfer coefficient of the ignition temperature of gangue and membrane wall tube bank pipe, anterior membrane wall tube bank pipe way distance is tuned up, to avoid fired brick burning not saturating, there is the situation of evil mind.
