Abstract
The present invention relates to the water-cooled grate that water route is arranged on a kind of fire grate beam, is to arrange that water pipe forms water route on fire grate beam；There are the water pipe of protrusion and the cooperation inside fire grate block in the position that two water pipes correspond to installation fire grate block on every beam, fire grate block is come into full contact with water pipe；Water-cooled grate is distributed in each row water pipe by the anterior water inlet of fire grate by horizontal header to be flowed out by the horizontal header of back of furnace row again；Water pipe on walking beam and laterally water inlet header and water outlet header use connection by metal hose, and the water pipe and transverse direction header on Jing Liang are directly connected to.The present invention can carry out simple reformation to existing air-cooled fire grate can reach water-cooled effect.
Description
Technical field
The present invention relates to burning facility field, and in particular to a kind of apply arranges knot in the water route of incinerator water-cooled grate
Structure, to change air-cooled fire grate.
Background technology
Because the species of rubbish is different, general house refuse, high heating value house refuse, industrial refuse, medical rubbish can be divided into
Rubbish, biomass garbage etc..Different refuse thermal value is different, wherein general MSW heating value is relatively low, at present mechanical kiln grate furnace with
The features such as its is adaptable, reliable, and controllability is high, gradually occupies the leading position of domestic garbage incineration equipment.
Traditional mechanical kiln grate furnace is based on air-cooled, and by fire grate, wind ash bucket is blown into burner hearth First air next time, First air
When being stopped in fire grate bottom, the special construction of fire grate segment bottom plays guide functions, guiding First air cooling fire grate segment surface, drop
Low temperature, 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.Adaptation of the water-cooled grate for refuse thermal value
Property it is stronger, make various garbage mix burn till for it is a kind of may, so as to increase economic benefit.
Traditional mechanical air-cooled fire grate is very universal, and can the rubbish of high heating value exists always, make sky in a short time
Black furnace row becomes that the water-cooled grate of high heating value rubbish can be burned.
The content of the invention
The purpose of the present invention overcomes the above problem, it is proposed that a kind of water route arrangement of water-cooled grate.
The concrete technical scheme of the present invention is that the water-cooled grate in water route is arranged on fire grate beam, is that water pipe is arranged on fire grate beam
Form water route；There are the water pipe of protrusion and matching somebody with somebody inside fire grate block in the position that two water pipes correspond to installation fire grate block on every beam
Close, fire grate block is come into full contact with water pipe；Water-cooled grate is distributed in each row water pipe by the anterior water inlet of fire grate by horizontal header
Flowed out again by the horizontal header of back of furnace row；Water pipe and horizontal water inlet header and water outlet header on walking beam use metal hose
Connect, the water pipe and horizontal header on Jing Liang are directly connected to.
Further, thermocouple is provided with fire grate segment lower part, stoker surface temperature is measured, fire grate is judged by temperature data
The incineration firing situation on surface, by adjusting the fire grate speed of service and cooling water inflow, reaches homogenous combustion.
Sufficiently cool to make, the special shape of fire grate block and water pipe adds contact area.
Fire grate segment does not arrange water route, identical with existing air-cooled fire grate plate shape.
The beneficial effects of the invention are as follows：
Due to the anterior water inlet rear portion water outlet of water-cooled grate of the present invention, whole fire grate forms inclining obliquely along rubbish travel direction
Angle, water pipe inclination angle cooling water identical with fire grate inclination angle make cooling water be full of water pipe, make by the hydraulic pressure of gravity and cooling water system
Each fire grate block has the contact of maximum area with water pipe, and full and uniform cooling effect avoids burning the impermeable and situation of burning hair
It is raw；This water-cooled grate can be changed by original air-cooled fire grate, it is only necessary to water pipe weight will be arranged on original air-cooled fire grate beam
New installation fire grate block, the maintenance of water cooling tube is also more convenient, and fire grate block is also more convenient with changing；Whole fire grate segment surface
Cooling effect is evenly；Efficient cooling enables fire grate to bear the fuel of more high heating value, is suitable for a variety of high heating value rubbish and mixes burning；
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
Piece surface temperature drops to less than 250 degrees Celsius, makes fire grate segment life-span upgrading more than 4 years, and maintenance period extends more than 20%, greatly
Reduce operation cost greatly.The present invention's another advantage is that can carry out simple reformation to existing air-cooled fire grate can reach
To water-cooled effect, cloth water cooling tube need to be only added on fire grate beam, the shape and form of the cooperation of fire grate block and water pipe can also bases
Concrete condition and change.

In figure：Beam water pipe, 105-water outlet are moved in 101-water inlet, 102-water inlet header, 103-quiet beam water pipe, 104-
Header, 106-dynamic beam metal hose, 107 supporting blocks, 108-fire grate block, 109-water outlet, 201-fire grate beam, 202-water
Pipe evagination cavity, 203-fire grate block indent cavity.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, recirculated cooling water is collected by the water inlet pipe 101 positioned at two forequarter of fire grate into water inlet
Case 102, water flows directly into quiet beam water pipe by way of in parallel, enters dynamic beam water pipe again by metal hose 106.By dynamic beam
Water pipe and each water pipe evagination cavity 202 of quiet beam water pipe are full of water such as Fig. 2.As shown in Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8,
Current are flowed into by water inlet pipe 101, and can flow into each by the water inlet header 102 of fire grate front portion is connected in parallel on into the water in water header
The water of 103,104 each pipes of pipe out flows into water outlet header 105 and is flowed out again from the water outlet header of back of furnace row, so protects always
Water flowing in water holding pipe plays the role of cooling.
Implementation result：
Air-cooled fire grate and water-cooled grate temperature comparisons
Table one（House refuse higher calorific value 3000kcal/kg, disposal ability 100t/d）
Embodiment interpretation of result：
The present invention is used for consumer waste incineration it can be seen from above result of implementation, and water-cooled grate surface temperature ensures at 130 DEG C
Left and right, under identical operating mode, 180 DEG C or so of air-cooled fire grate temperature peak point and water-cooled grate temperature peaks value difference.To the whole of fire grate
Body cooling-down effect is notable.
