Description

The special-purpose coal furnace of a kind of horizontal seawater
Technical field
The utility model relates to a kind of environmental protection and energy saving coal furnace, specifically is the special-purpose coal furnace of a kind of horizontal seawater, belongs to the coal furnace technical field of structures.
Background technology
Used boiler was main with straight burning mode during marine product was cultured at present; Coal is in the burner hearth internal combustion; Constantly discharge a large amount of flue gas and dust, the discharging of dust not only produces atmosphere pollutes a large amount of flammable little buckwheat coals of also having carried under one's arms simultaneously; Partial heat energy is taken away in the discharging of flue gas again, causes waste.And adopting the coal furnace consumption coal of suitable burning method many, heat is imitated low and serious environment pollution.Though this problem once had taked different corrective measures,, can't fundamentally overcome shortcoming on fume extractor along burning method coal furnace such as various forms of dust arresters are installed.Along with the fast development of coastal aquaculture, provide a kind of energy-saving, environmental protection boiler to become the active demand of aquaculture.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design, low, the hot special-purpose coal furnace of horizontal seawater high, no dust emission of imitating of energy consumption are provided.
The utility model is realized through following technical scheme:
The special-purpose coal furnace of a kind of horizontal seawater; Its special feature is to be composed in series through flue by main stove and secondary stove; Main stove comprises that the lower fire grating 2 that is arranged on the peripheral outer courage 16 of boiler, the inner bag 17 of outer courage parcel, the coal feed point 8 that is arranged on the burner hearth side, burner hearth bottom and Dust Storage Room 1, the Hybrid Heating that is connected with burner hearth block fire tube crowd 9 and flue 10; Burner hearth is divided into upper combustion chamber 5 and lower combustion chamber 3 by water-cooled grate 4; The top of upper combustion chamber 5 be provided with communicate with upper combustion chamber on block fire tube crowd 6, burner hearth and Hybrid Heating are blocked and are provided with the water jacket 7 that increases heating surface area between the fire tube crowd 9.
Said secondary furnace interior is provided with pair and blocks that fire tube crowd 11, bottom are provided with whirlpool wind dirt pocket 12, whirlpool wind dirt pocket communicates with exhaust opening 13.
Say and block that fire tube crowd 6, Hybrid Heating block fire tube crowd 9, pair is blocked fire tube crowd 11 and all adopted the screwed pipe material that can improve heat conduction efficiency to process.
The course of work of the utility model: light the fuel in the upper combustion chamber 5 after being ignited by combustibles such as thin timber etc., fuel enlarges flame in natural oxygenation, and temperature improves constantly in the inner bag; Flame rushes at downwards arranges the water-cooled grate of dredging 4, gets into lower combustion chamber, and a part of dust and live charcoal fall into lower combustion chamber 3 and burn away; Form double-deck burning with the fuel on the lower fire grating 2, the repeated oscillation of burning up and down is until tiny powder is burnt down; Double-deck up and down red-hot flame makes fuel combustion thoroughly and fully, and when heating up significantly, the powdery flue dust of being carried secretly in the flue gas is settled down to Dust Storage Room 1 bottom; Be trapped at Dust Storage Room, regularly remove; Flue dust is directly externally discharging not; High-temperature flue gas passes water jacket 7, blocks fire tube crowd 9 through Hybrid Heating and is absorbed the part heat, gets into secondary stove through flue 10 again; Block fire tube crowd 11 through pair and absorb heat once more; Get into the whirlpool wind dirt pocket 12 of bottom then, by air-introduced machine 14 cigarette ash is introduced chimney 15 through exhaust opening 13 and discharge, accomplish combustion process.
Seawater is introduced into secondary stove, blocks fire tube crowd 11 through the pair of secondary furnace interior, the laggard stove of becoming owner of that once is heated, through blocking that fire tube crowd 6, Hybrid Heating block that fire tube crowd 9 and water jacket 7 are heated after the delivery port of main furnace roof portion discharge.
The utility model flue dust is few, heat is imitated high reason and is: aflame coal grain dashes to lower combustion chamber down; Mix hugging in lower combustion chamber with lower fire grating formation; Burning is thorough, and until burning-out, flue dust can not arranged to air; The heat that burning produces successively by on block fire tube crowd, Hybrid Heating and block and secondaryly in fire tube crowd and the secondary stove block the Absorption by Sea Water in the fire tube crowd, thermal loss is few; The overall process of burning is close in heat-insulating and sealing carries out, and environmental protection and energy saving are superior to traditional coal furnace, adopts efficient screw thread nest of tubes 6 can strengthen heat transfer area in the combustion chamber, delays the flame rate of climb, improves heat conduction efficiency.The utility model coal furnace can be designed to normal pressure or pressure-bearing coal furnace, heat supply simultaneously, and supply drinking water.
The utility model advantage:
1, integral type design, simple in structure.The utility model changes the burner of plain cylindrical furnace into the counter-burning type burner and directly adds hot sea water, and the working method of burner and plain cylindrical furnace are different, and the structure of this burner is simpler, and is easy to safeguard.
2, energy consumption is low, the heat effect is high.Owing to adopt counter-burning type oxygenation burning, add coal-fired burning repeatedly in upper combustion chamber and lower combustion chamber, coal-fired heat energy is close under the sealing state of thermal isolation fully discharges; Blocking fire tube crowd and Hybrid Heating on the main furnace interior blocks the fire tube crowd and absorbs a large amount of heats; Pair is blocked the fire tube crowd and is absorbed heat once more in secondary stove again, and its heat transference efficiency is higher than traditional coal furnace, can reach 85.85% through the test thermal efficiency; Fractional energy savings can reach 27%, and rate can reach more than 12% during joint.
3, no dust emission, compliance with environmental protection requirements.The utility model coal furnace; Fuel is close under the sealing state of thermal isolation and fully burns; The coal-fired flue dust major part that produces falls in the main stove Dust Storage Room, and flue gas gets into behind the secondary stove in the whirlpool wind dirt pocket and all held back, and carries out Timing Processing; Contamination particle such as no flue dust in the waste gas of discharging during normal combustion, compliance with environmental protection requirements.
4, the little and good operational environment of volume.Add the dedusting fume extractor because the utility model coal furnace cancellation is traditional, volume obviously reduces, the sanitary condition of boiler room be improved significantly, good operational environment.
