Description
Technical field
The present invention relates to the field of burning, and in particular to a kind of water bar applied on incineration furnace grate.
Background technology
Since the species of rubbish is different, house refuse, high heating value house refuse, industrial refuse, medical waste, life can be divided into
Material rubbish etc..Wherein MSW heating value is relatively low, and mechanical kiln grate furnace is adaptable, reliable with its rubbish at present, controllable
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
When wind is stopped in fire grate bottom, by the labyrinth arrangement of air-cooled fire grate segment bottom, guide functions, guiding First air cooling are played
The temperature on fire grate segment surface, prevents fire grate scaling loss.
But air-cooled cooling effect is limited, it 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 and then shadow
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 becomes a kind of trend.
Water bar is stronger for the adaptability of refuse thermal value, mixes various garbage and burns till to be a kind of possible, so as to increase economic effect
Benefit.
The content of the invention
The purpose of the present invention overcomes above-mentioned the deficiencies in the prior art, it is proposed that a kind of water cooling stove of pipe laying integrally casting shaping
Screening.
The present invention concrete technical scheme be：
A kind of water bar of pipe laying casting, which is casting, and cooling water is embedded with the body
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, and
Welded stub connection, easy to be connected with cooling water system；Two interfaces of the other end of the cooling water pipe of told fire grate segment pass through company
Adapter is connected, and circulates easy to cooling water in fire grate segment water cavity.
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 on surface is arranged, by adjusting the fire grate speed of service, increases and decreases air quantity, adjusts the means such as water speed, can effectively avoid
The leakage of water cavity occurs, while also improves incinerator integral combustion efficiency.
Supplied water during present invention operation by recirculating cooling water system, outer water tube connects with water inlet connection and water outlet joint
Connect, meanwhile, be connected by stainless steel connecting tube with interface, current are flowed into by water inlet, flow into fire grate segment cooling water pipe compared with
In big U-tube, then less U-tube flow to by connecting interface and stainless steel connecting tube, eventually through water outlet joint stream
Go out, water bar is cooled down by way of thermal convection current.
The beneficial effects of the invention are as follows：
Due to water bar pipe laying casting of the present invention, water cooling tubing uses seamless steel pipe, and connecting tube material is using stainless
Steel；Double-U-shaped cooling water pipe longitudinal arrangement arrangement makes cooling water more abundant in the fire grate segment internal stops time, whole fire grate segment surface
Cooling effect is evenly；When leakage situation occurs for cooling water, air-cooled replacement can be used, main body is air-cooled to nor affect on whole fire grate system
System operation；Efficient cooling lifts the thermal value range of combustible substance, is suitable for various garbage and mixes burning；Relatively air-cooled fire grate, it is cold
But fire grate segment is reduced with air, is more suitable for low latitude gas than burning, to reduce smoke discharge amount；Fire grate segment surface temperature is dropped to
Less than 250 degrees Celsius, make fire grate segment life-span upgrading more than 5 years, maintenance period extends more than 20%, greatly reduces operation cost.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, water bar body 1 is casting, and cooling water pipe 2 wraps in casting process
Be contained in water bar 1, fire grate segment bottom there are cooling water pipe epitaxial part, 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 during operation
System water supply, outer water tube are connected with water inlet connection 3 and water outlet joint 4, meanwhile, pass through stainless steel connecting tube 6 and interface 5
It is connected, current are flowed into by water inlet, are 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 less U-tube, is flowed out eventually through water outlet joint 4, to water-cooled grate by way of thermal convection current
Piece is cooled down.
Whole 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, thermocouple support base 201 is welded with standard water bar bottom, fire grate segment interior front is welded with thermocouple
Mounting base 203, has screw thread inside both, easy to the installation of thermocouple.Threading steel pipe 202 is welded between the two, with protection
Thermocouple wire.
Because above-mentioned fire grate is slides, fixed alternating expression arrangement, all rubbish can be subject to the masterpiece that rubs on fire grate
With rolling, so making the loose effect of rubbish more preferable, burning is more uniform.Original air-cooled fire grate instead of by water bar
Piece, it is stronger to the adaptability of refuse thermal value, mix various garbage and burn till to be a kind of possible, so as 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 less than 250 degrees Celsius, makes fire grate segment life-span upgrading more than 5 years, and maintenance period extends more than 20%, substantially reduces
Operation cost.
