Specific embodiment
In the following description, a large amount of concrete details are given more thoroughly to manage in order to provide to the utility model
Solution.It will be apparent, however, to one skilled in the art that the utility model embodiment may not need one or more
These details and be carried out.In other examples, in order to avoid obscuring with the utility model embodiment, for ability
Some technical characteristics well known to domain are not described.
In order to thoroughly understand the utility model embodiment, detailed structure will be proposed in following description.Obviously, this reality
The specific details that those skilled in the art is familiar with are not limited to the execution of new embodiment.The utility model it is preferable
Embodiment is described in detail as follows, however other than these detailed descriptions, the utility model can also have other embodiments.
As previously mentioned, existing domestic waste incineration fire grate segment mainly uses cooling air to cool down it, so that
The unbearable higher temperature of fire grate segment, so domestic waste incineration can not the higher industrial refuse of incinerating combustion value.According to
Water-cooled grate burning domestic garbage leads to certain energy dissipation because recirculated water is constantly passed through fire grate segment by water circulating pump, and
And recirculated water takes away a large amount of heat, the temperature inside incinerator is unable to get guarantee.Therefore it needs to find a kind of with controllable
The garbage incinerator fire grate of cooling system makes it directly use cold air to carry out it when burning the house refuse of low heat value cold
But；When burning the industrial refuse of high heating value, it is cooled down using cooling circulating water, while can be according to the calorific value of rubbish
The flow of recirculated water is adjusted, fire grate is made to realize the maximization of economic benefit when reaching cooling effect.The utility model
Based on this, proposes a kind of garbage incinerator fire grate and incinerator, makes waste incinerator that can both burn high heating value industrial refuse,
Low heat value house refuse can be burned again, and reaches saving energy under the premise of guaranteeing combustion efficiency.
Fig. 1 shows the structural schematic diagram of the garbage incinerator fire grate according to the utility model embodiment.Below with reference to Fig. 1 to root
It is described in detail according to the garbage incinerator fire grate of the utility model embodiment.
As shown in Figure 1, garbage incinerator fire grate 100 provided in this embodiment include set gradually first segment fire grate segment 11,
Second segment fire grate segment 12,13, the 4th sections of fire grate segments 14 of third section fire grate segment and the 5th section of fire grate segment 15, wherein first segment fire grate segment
11 are mainly used for that rubbish is dried, and constitute the drying unit of garbage incinerator fire grate 100, second segment fire grate segment 12, third
Section fire grate segment 13 and the 4th section of fire grate segment 14 are mainly used for burning away the refuse, and constitute the fuel element of garbage incinerator fire grate 100, the
Remaining uncombusted rubbish after-flame is constituted the after-flame unit of garbage incinerator fire grate 100 by five sections of fire grate segments 15.
Every section of fire grate segment (i.e. the first segment fire grate segment 11, second segment fire grate segment 12,13, the 4th sections of third section fire grate segment
Fire grate segment 14 and the 5th section of fire grate segment 15) it include the fire grate segment that several row's ladders are arranged, every grate furnace screening includes that several levels are set
The fire grate segment set, and fire grate segment described in every row includes fixed grate film and sliding fire grate segment.Illustratively, in the present embodiment
In, every section of fire grate segment includes the fire grate segment of six row's ladders setting, and has three rows to be in the fire grate segment of six rows ladder setting
Fixed grate film, three rows are sliding fire grate segment, and fixed grate film and the setting of sliding fire grate segment interval, sliding fire grate segment are used for
Rubbish thereon is moved to the fire grate segment of next row, being arranged such, which realizes rubbish, is burning the movement on fire grate.
Although should be appreciated that in the present embodiment, drying unit includes and after-flame unit includes primary reformer screening, burning is single
Member includes three sections of fire grate segments, but is can according to need in other embodiments using other suitable quantity.
Since drying unit is for being dried rubbish, and fuel element is used to fire in remaining uncombusted rubbish
To the greatest extent, therefore the temperature of drying unit and fuel element is lower, and either for house refuse or industrial refuse, fire grate segment makes
It can satisfy cooling effect completely with air cooling.And higher for temperature fuel element (such as second segment fire grate segment 12,
Three sections of fire grate segments 13 and the 4th section of fire grate segment 14) for, in order to allow to the rubbish suitable for various calorific values, in the present embodiment
In, it is provided with cooling water circulation unit for it, is passed through cooling water described in cooling for the fire grate segment into the fuel element
The fire grate segment of fuel element.The cooling water circulation unit includes cooling water pipe and and is arranged on the cooling water pipe for adjusting
Save the water cooling valve of cooling water inflow.When the lower house refuse of combustion heat value is, water cooling valve is closed, at this time cooling water pipe
In do not intake, entire garbage incinerator fire grate is cooled down using air；When the higher industrial refuse of combustion heat value, water-cooled valve
Door is opened, and is intake, i.e., is cooled down in cooling water pipe using fire grate segment of the cooling water to fuel element at this time, to make fire grate temperature
Degree reduces, and prolongs its service life.
The another aspect of the utility model also provides a kind of incinerator comprising cavity, and setting is in the cavity
Garbage incinerator fire grate as described above.
Garbage incinerator fire grate and incinerator according to the present utility model begin to the lower drying unit of temperature and after-flame unit
It is cooled down eventually using air-cooled mode, and cooling water circulation unit then is arranged with thereto for it to the higher fuel element of temperature
Fire grate segment be passed through cooling water, therefore when the low house refuse of incinerating combustion value, the water cooling valve of cooling water circulation unit is closed,
All fire grate segments are all made of method for air-cooling cooling, realize the saving of energy, and when the higher industrial refuse of incinerating combustion value, water cooling
Valve fully opens, and is cooled down using fire grate of the cooling water to fuel element, achievees the purpose that protect fire grate segment.
Garbage incinerator fire grate and incinerator according to the present utility model both can be with the higher industrial refuses of incinerating combustion value, can also
With the lower house refuse of incinerating combustion value, and can be realized to fire grate segment by controlling the aperture of water cooling valve to different calorific values
The adaptability of refuse thermal value, so as to can be to burning when all rubbish of the incinerating combustion value between industrial refuse and house refuse
Fire grate is burnt reasonably to be cooled down.
