Description
Technical field
The utility model is related to the fields of burning, and in particular to a kind of water bar applied on incineration furnace grate.
Background technology
Since the type of rubbish is different, house refuse, high heating value house refuse, industrial refuse, medical waste, life can be divided into
Substance rubbish etc..Wherein MSW heating value is relatively low, and mechanical kiln grate furnace is adaptable, reliable for operation with its rubbish at present, controllably
The features such as property is high, gradually occupies the leading position of consumer waste incineration.
Traditional mechanical kiln grate furnace is based on air-cooled, and by fire grate, First air is blown into burner hearth by wind ash bucket next time, once
Wind, by the labyrinth arrangement of air-cooled fire grate segment bottom, plays guide functions, guiding First air cooling when fire grate bottom is stopped
The temperature on fire grate segment surface prevents fire grate scaling loss.
But air-cooled cooling effect is limited, is not particularly suited for the higher Other Waste of calorific value and burns.
The fire grate segment of existing stoker fired grate does not have water cooling function, and fuel tolerance is poor, when the combustion of burning higher thermal value
Material, such as biomass, can cause fire grate segment surface temperature to be up to four or five hundred degree.Improve the frequency of replacing fire grate bar, and shadow in turn
The operation cost and economic benefit of municipal solid waste incinerator are rung.In order to make mechanical kiln grate furnace in the higher high heating value life of calorific value
Rubbish, industrial refuse, medical waste and biomass garbage are also had place to show one's prowess in burning, and water cooling design has become a kind of trend.
Water bar is for the more adaptable of refuse thermal value, and it is a kind of possibility so that various garbage is mixed firing, to increase economic effect
Benefit.
Invention content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, it is proposed that a kind of water of pipe laying integrally casting shaping
Black furnace screening.
The specific technical solution of the utility model is：
A kind of water bar of pipe laying casting, which is casting and forming, is embedded in the ontology cold
But water pipe, cooling water pipe are used as water cavity in fire grate segment；One end of the cooling water pipe of the fire grate segment is equipped with water inlet, water outlet
Mouthful, and welded stub connection, convenient for being connect with cooling water system；Two interfaces of the other end of the cooling water pipe of told fire grate segment are logical
It crosses connecting tube to be connected, circulate in fire grate segment water cavity convenient for cooling water.
Further, in order to make the water in cooling water pipe play uniform cooling effect, cooling water pipe is double-U-shaped longitudinal arrangement
It is arranged in inside fire grate.
Further, water bar lower part is provided with thermocouple, measures stoker surface temperature, judges stove by temperature data
The incineration firing situation for arranging surface increases and decreases air quantity, adjusts the means such as water speed, can effectively avoid by adjusting the fire grate speed of service
The leakage of water cavity occurs, while also improving incinerator integral combustion efficiency.
The utility model is supplied water when running by recirculating cooling water system, outer water tube and water inlet connection and water outlet joint
Connection, meanwhile, it is connected with interface by stainless steel connecting tube, flow is flowed by water inlet, flows into cooling water pipe in fire grate segment
In larger U-tube, then smaller U-tube flow to by connecting interface and stainless steel connecting tube, eventually by water outlet joint
Outflow, cools down water bar by way of thermal convection current.
The utility model has the beneficial effects that：
Due to the utility model water bar pipe laying casting and forming, water cooling tubing uses seamless steel pipe, connecting tube material
Using stainless steel；Double-U-shaped cooling water pipe longitudinal arrangement arrangement keeps cooling water more abundant in the fire grate segment internal stops time, entire stove
Screening surface cooling effect is evenly；When leakage situation occurs for cooling water, air-cooled replacement can be used, main body is air-cooled nor affect on it is whole
A fire grate system operation；Efficient cooling makes the thermal value range of combustible substance be promoted, and is suitable for various garbage and mixes burning；It is relatively air-cooled
Fire grate, cooling fire grate segment are reduced with air, are more suitable for low latitude gas than burning, to reduce smoke discharge amount；By fire grate segment surface temperature
Degree drops to 250 degrees Celsius hereinafter, making fire grate segment life-span upgrading 5 years or more, and maintenance period extends 20% or more, greatly reduces
Operation cost.

Specific implementation mode
As shown in Figure 1, Figure 2 and Figure 3, water bar ontology 1 is casting and forming, and cooling water pipe 2 wraps in casting process
Be contained in water bar 1, there are the epitaxial parts of cooling water pipe for fire grate segment bottom, and weld water inlet connection 3, water outlet connects
First 4 and pass through two jointings 5 that stainless steel connecting tube 6 is responsible for the double-U-shaped cooling water pipe of connection.By recirculated cooling water when operation
System water supply, outer water tube are connect with water inlet connection 3 and water outlet joint 4, meanwhile, pass through stainless steel connecting tube 6 and interface 5
It is connected, flow is flowed by water inlet, is flowed into the larger U-tube of cooling water pipe in fire grate segment, then by connecting interface 5 and not
Rust steel connecting tube 6 flow to smaller U-tube, is flowed out eventually by water outlet joint 4, to water-cooled grate by way of thermal convection current
Piece is cooled down.
Entire fire grate frame walking beam can be evenly arranged band heat with fixed beam interlaced arrangement, on stationary furnace stringer on demand
Galvanic couple water bar 102, remaining is standard water bar 101, as shown in Figure 4.Band thermocouple water-cooled grate chip architecture is such as
Shown in Fig. 5, it is welded with thermocouple support base 201 in standard water bar bottom, fire grate segment interior front is welded with thermocouple
Mounting base 203 has screw thread inside the two, is convenient for the installation of thermocouple.It is welded with threading steel pipe 202 between the two, with protection
Thermocouple wire.
Because above-mentioned fire grate is sliding, fixed alternating expression arrangement, all rubbish can be by friction masterpiece on fire grate
With rolling, so keeping the loose effect of rubbish more preferable, burning is more uniform.By water bar instead of original air-cooled fire grate
Piece, to the more adaptable of refuse thermal value, it is a kind of possibility so that various garbage is mixed firing, to increase economic benefit.It is relatively empty
Black furnace is arranged, and cooling fire grate segment is reduced with air, is more suitable for low latitude gas than burning, to reduce smoke discharge amount.By fire grate segment surface
Temperature drops to 250 degrees Celsius hereinafter, making fire grate segment life-span upgrading 5 years or more, and maintenance period extends 20% or more, substantially reduces
Operation cost.
