Description
Technical field
The present invention relates to incinerator field, in particular it relates to a kind of side wall water bar and incinerator.
Background technology
Waste incineration is one of main path realizing garbage decrement, innoxious and recycling treatment.Rubbish burns at present
Burning the main path being increasingly becoming garbage disposal, rubbish is through the burning disposal of modernization, and volume typically can reduce 80%-
90%, various pathogen can be eliminated simultaneously, harmful substance is converted into harmless object, it is also possible to realize the utilization of resource.?
The existing multiple domestic waste incineration of China comes use, existing waste incineration many employings mechanical garbage incinerator, rubbish
Pour incinerator into from charging aperture, enter burning in described incinerator by rubbish described in the reciprocating effect of feed fire grate
Burn on fire grate and burn, incineration firing totally after, remaining slag enters slag-drip opening, slag-drip opening discharge out of the furnace.
Side wall fire grate segment is the common part of the middle use at grate furnace.Existing side wall fire grate segment generally uses founder
Skill produces, and is arranged on incinerator structural framing.Substantial amounts of heat can be produced when fuel burns on fire grate segment and be radiated side
The surface of wall fire grate segment, thus the working environment of side wall fire grate segment is the most severe, generally at high temperature, easy to wear, the ring of corrosion
Working under border, therefore, the design of the heat dissipation design of side wall fire grate segment, structure and material select to determine its making in the presence of a harsh environment
With the life-span, thus determine the frequency of side wall replacing fire grate bar, the operating cost of grate furnace and economic benefit.Existing rubbish burns
The fire grate segment burnt and the fire grate segment of biomass fire grate have respective shortcoming, the fire grate segment of rubbish fire grate not to have water cooling function, combustion
Material bad adaptability, when the fuel of burning higher thermal value, such as biomass etc., can cause fire grate segment surface temperature to be up to four or five hundred degree,
And existing biomass fire grate causes consumptive material more owing to water cooling tube is wholly embedded in fire grate segment so that fire grate relatively costly, warp
Ji benefit is poor.
Therefore, it is necessary to propose a kind of novel side wall fire grate segment, to solve the problems referred to above.

Detailed description of the invention
In the following description, a large amount of concrete details is given to provide more thorough understanding of the invention.So
And, it is obvious to the skilled person that the present invention can be able to without these details one or more
Implement.In other example, in order to avoid obscuring with the present invention, technical characteristics more well known in the art are not entered
Line description.
In order to thoroughly understand the present invention, detailed step will be proposed in following description, in order to explaination is the present invention propose
The side wall water bar of incinerator.Obviously, the execution of the present invention be not limited to those skilled in the art institute ripe
The specific details practised.Presently preferred embodiments of the present invention is described in detail as follows, but in addition to these describe in detail, the present invention also may be used
To have other embodiments.
It should be appreciated that when using term " to comprise " in this manual and/or time " including ", it indicates that existence is described
Feature, entirety, step, operation, element and/or assembly, but do not preclude the presence or addition of other features one or more, entirety,
Step, operation, element, assembly and/or combinations thereof.
The present invention provides a kind of side wall water bar, as shown in Figure 1 and Figure 2, including header board 1, back plate 2, internal water cavity 3,
