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.
Therefore in order to make mechanical kiln grate furnace in calorific value higher high heating value house refuse, industrial refuse, medical waste and life
Also have place to show one's prowess in material waste incineration, water cooling design becomes a kind of trend.Water bar is for the suitable of refuse thermal value
Answering property is stronger, mixes various garbage and burns till to be a kind of possible, so as to increase economic 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 bar of casting.
The present invention concrete technical scheme be：
A kind of water bar of casting, the water bar body are casting, are cast with internal water cavity, fire grate segment
Bottom is cast with entery and delivery port, and welds water inlet connection and water outlet joint, easy to be connected with water cooling tube；In internal water cavity
Between be cast with water conservancy diversion gusset.
Further, in order to make the water in water cavity play uniform cooling effect, water cavity is arranged in fire grate for U-shaped longitudinal arrangement
It is internal.
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 means such as the fire grate speed of service, increase and decrease air quantity, improves incinerator integral combustion effect
Rate.
Supplied water during present invention operation by recirculating cooling water system, water pipe is connected with water inlet connection and water outlet joint, water
Stream is flowed into by water inlet, by U-shaped internal water cavity in fire grate, is flowed out from water outlet, to water-cooled grate by way of thermal convection current
Piece is cooled down.Whole fire grate frame walking beam can be evenly arranged on demand with fixed beam interlaced arrangement, on stationary furnace stringer
Band thermocouple water bar, remaining is standard water bar.Thermocouple support is welded with standard water bar bottom
Seat, fire grate segment interior front is welded with the installation of TC seat, has screw thread inside both, easy to the installation of thermocouple.Both it
Between be welded with threading steel pipe, to protect thermocouple wire.
The beneficial effects of the invention are as follows：
It is wider to the adaptability of fire grate segment material since water bar of the present invention is casting；Built-in water cavity imitates cooling
Fruit is optimal；U-shaped water cavity longitudinal arrangement arrangement makes cooling water more abundant in the fire grate segment internal stops time, whole fire grate segment table
Face 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 operation；Efficient cooling lifts the thermal value range of combustible substance, is suitable for various garbage and mixes burning；Relatively air-cooled fire grate,
Cooling 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 declined
To less than 250 degrees Celsius, make fire grate segment life-span upgrading more than 5 years, maintenance period extend more than 20%, greatly reduce operation into
This.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, water bar body 1 is casting, casts out internal water cavity 2, fire grate segment bottom
Portion is cast with entery and delivery port, and welds water inlet connection 3 and water outlet joint 4, and water conservancy diversion gusset 5 is cast among internal water cavity.Fortune
Being supplied water during row by recirculating cooling water system, water pipe is connected with water inlet connection 3 and water outlet joint 4, and current are flowed into by water inlet,
By U-shaped internal water cavity 2 in fire grate, flow out from water outlet, water bar is cooled down by way of thermal convection current.Entirely
Fire grate frame walking beam can be evenly arranged band thermocouple water-cooled grate with fixed beam interlaced arrangement, on stationary furnace stringer on demand
Piece 102, remaining is standard water bar 101, as shown in Figure 4.Band thermocouple water-cooled grate chip architecture is as shown in figure 5, marking
Quasi- water bar bottom is welded with thermocouple support base 201, and fire grate segment interior front is welded with the installation of TC seat 203, and two
There is screw thread inside person, easy to the installation of thermocouple.Threading steel pipe 202 is welded between the two, to protect 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.
