Description
Technical field
The present invention relates to burning city domestic garbage field, especially a kind of incinerator water-cooled furnace wall device.
Background technology
Incinerator burner hearth coking is to need one of problem of emphasis consideration when incinerator burner hearth is designed.Incineration firing is produced
Raw high temperature fusing fly ash thing is attached to burner hearth inner side, can not only shorten the service life of refractory brick, and can hinder incinerator
Continuous operation.With the continuous rising of refuse thermal value, existing air cooled wall is to the deficiency of high heating value waste incineration adaptability, nothing
Method effectively suppresses burner hearth coking.
The content of the invention
In order to solve during high heating value incineration firing, the problem of incinerator burner hearth coking, the present invention proposes a kind of life rubbish
Rubbish incinerator water-cooled furnace wall device.
Concrete technical scheme of the invention is：
A kind of domestic waste incineration water-cooled furnace wall device, including water screen tube, lower header, silicon carbide pour refractory material,
SiC-85 refractory brick and refractory brick bear component；Described water screen tube is fin panel casing；Described lower header is located at water
Cold wall pipe bottom, with water screen tube by being welded to connect；Described silicon carbide pours refractory material and invests water screen tube surface；
Described SiC-85 fire resistings are brick in water screen tube bottom, next part upper box part；Described refractory brick bears component positioned at lower header
The water screen tube surface on top, is connected by welding with water screen tube, is played support silicon carbide and is poured refractory material and SiC-
The effect of 85 refractory brick.
During work, the water from drum enters lower header through down-comer, and the water in lower header is evenly distributed and enters water-cooling wall
With silicon carbide refractory material being poured in pipe and SiC-85 refractory brick being exchanged heat, SiC-85 refractory brick surface temperatures are reduced to
700 ~ 800 DEG C, can effectively suppress the carbonated drink after generation, attachment and the growth, and heat absorption of burner hearth coking and return to drum, can carry
The yield of Boiler Steam high.
Domestic waste incineration water-cooled furnace wall device of the present invention based on above-mentioned design, due to：1, using the original of heat exchange
Refractory brick surface temperature can be reduced to 700 ~ 800 DEG C by reason, water-cooled furnace wall, can effectively suppress generation, the attachment of burner hearth coking
And growth, deficiency of the air cooled wall to high heating value incineration firing adaptability is improved, can preferably adapt to the combustion of high heating value rubbish
Burn；2, the application of water-cooled furnace wall, it is possible to reduce the consumption of cooling air, so as to reduce the exhaust smoke level of boiler, reduce exhaust gas heat loss
Lose；3, relative to air cooled wall, the heat absorption coefficient of water-cooled furnace wall is higher, so as to improve effective caloric receptivity of boiler, reaches and carries
The purpose of boiler efficiency high；4, water-cooled furnace wall heat absorption capacity is stronger, and the temperature of combustion chamber can be higher than air cooled wall be used, so that full
The high-temp combustion of sufficient combustion chamber, can promote the decomposition of bioxin, reduce the discharge of dioxin pollutant.5, SiC-85 refractory brick
With good wearability and conductivity of heat, for the position that fire grate top side wall bottom contacts with rubbish, good abrasionproof is played
Damage the effect with anti-coking.In sum, domestic waste incineration water-cooled furnace wall device of the present invention can efficiently solve existing sky
The drawbacks of black furnace wall is not enough to high heating value incineration firing adaptability, is favorably improved incinerator heat utilization efficiency, reduces Er Evil
The discharge of English pollutant, and then reach the purpose of energy-saving and environmental protection.Thus, the present invention substantially has rational in infrastructure, reliable
With the characteristic of energy-conserving and environment-protective, there is very strong practicality and considerable market application foreground.

Specific embodiment
Below in conjunction with the accompanying drawings and exemplary embodiments are described in further detail to the present invention.
In fig. 1 and 2, domestic waste incineration water-cooled furnace wall device of the invention, main body include water screen tube 1, under
Header 2, silicon carbide pours refractory material 3, SiC-85 refractory brick 4 and refractory brick and bears component 5.Described water screen tube 1
It is film water cold wall structure；Described lower header 2 is located at the bottom of water screen tube 1, with water screen tube 1 by being welded to connect；It is described
Silicon carbide pour refractory material 3 and invest the surface of water screen tube 1；Described SiC-85 refractory brick 4 is built under water screen tube 1
Portion, the top of lower header 2, SiC-85 refractory brick 4 has good wearability and conductivity of heat；Described refractory brick bears component 5
In the surface of water screen tube 1 on the top of lower header 2, it is connected with water screen tube 1 by welding, plays support silicon carbide and pour fire resisting
The effect of material 3 and SiC-85 refractory brick 4.
During work, the water from drum enters lower header 2 through down-comer, and the water in lower header 2 is evenly distributed and enters water-cooled
With silicon carbide refractory material 3 is poured in wall pipe 1 and SiC-85 refractory brick 4 is exchanged heat, by SiC-85 refractory brick surface temperatures
700 ~ 800 DEG C are reduced to, can effectively be suppressed the carbonated drink after generation, attachment and the growth, and heat absorption of burner hearth coking and be returned to vapour
Bag, can improve the yield of Boiler Steam.
The present invention is rational in infrastructure, reliable, and the water from drum enters lower header through down-comer, and the water in lower header is equal
Even distribution is exchanged heat into water screen tube with highiy refractory brick, and the carbonated drink after heat absorption returns to drum.Burning can effectively be reduced
Stove furnace wall temperature, improves deficiency of the existing air cooled wall to high heating value waste incineration adaptability, is favorably improved waste incineration
Stove heat utilization efficiency, reduces the discharge of dioxin pollutant, and then reaches the purpose of energy-saving and environmental protection, have very strong practicality and
Considerable market application foreground.
