Abstract
The embodiment of the invention discloses a garbage incinerator for preventing furnace slagging. The garbage incinerator comprises an incinerator grate, an incinerator body, auxiliary burners, a wall-attached air pipe, deslagging holes and a cooling water spraying-back opening. The incinerator body is arranged with the incinerator grate in an up-down corresponding manner. Air bellows are arranged on incinerator walls on two sides of the incinerator body. The auxiliary burners are arranged on dry sections of the incinerator walls of the incinerator body. The wall-attached air pipe penetrates through the air bellows and enters into a furnace of the incinerator body, and is flush with a rear arch part in the furnace. The deslagging holes are formed in the incinerator walls on the two sides on the outer side of the furnace. The wall-attached air pipe is arranged with the deslagging holes in an up-down corresponding manner. The cooling water spraying-back opening is formed with the deslagging holes in a left-right corresponding manner. According to the garbage incinerator, the wall-attached air pipe is arranged, and cooling air is blown in the furnace through the wall-attached air pipe; the auxiliary burners are arranged, and the cooling water spraying-back opening is formed, so that the furnace temperature is reduced, and the coking is effectively controlled; and besides, the deslagging holes are formed in the incinerator walls on the two sides on the outer side of the furnace, so that real-time deslagging is conducted during the operation of the incinerator, and the further coking degradation is prevented.
Description
Technical field
The present invention relates to a kind of incinerator, particularly relate to a kind of incinerator preventing burner hearth coking.
Background technology
Along with Urbanization Construction paces stably develop in a healthy way, solving the current maximally effective way of garbage-surrounded city is exactly
With domestic waste as fuel, by using advanced garbage incineration technology and equipment to process rubbish, it is achieved
" innoxious, minimizing and the resource " of domestic waste.For solving garbage-surrounded city problem, have every year
Increasing garbage power plant puts into operation in succession, affects the core that garbage power plant long period efficient stable runs
Equipment is incinerator.The waste incineration type of furnace of main flow was mechanical kiln grate furnace and Circulation fluidized-bed furnace, wherein the present age
Grate furnace accounts for main flow direction, but waste incineration and generating electricity industry exists because incinerator burner hearth coking is made the most always
Becoming the problem that cycle of operation is shorter, this problem is a bottle of a restriction refuse-burning plant stable and high effective operation
A neck difficult problem, it directly influences whether domestic waste can process timely and effectively.
The coking process burning burner hearth is that the ash in Refuse Incineration Process is at high temperature molten into liquid or in softening
State, when encountering heating surface, forms coking.The ash of bonding gets more and more, and ultimately forms large-area Jiao
Block, block flue gas circulation passage, cause flue gas flow area to die-off, cause incinerator cannot normal combustion,
Finally can only be forced blowing out.
The factor controlling waste incineration coking mainly has: the first, the control of fire box temperature, controls waste incineration
The flying dust produced is in its deformation temperature (DT) below；The second, fusion point of ash, fusion point of ash is the highest more does not allows
Easily coking.Otherwise, fusing point is the lowest, the easiest coking；3rd, timely ash-cleaning and coke-removing.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, for when incineration firing, burns in burner hearth
The ash of bonding gets more and more, and ultimately forms large-area coke button, blocks flue gas circulation passage, causes flue gas to lead to
Flow area is die-offed, cause incinerator cannot normal combustion, cycle of operation is short, it is impossible to enough continuous and steady operations
Problem, it is proposed that a kind of incinerator preventing burner hearth coking.
In order to solve above-mentioned technical problem, embodiments provide a kind of rubbish preventing burner hearth coking and burn
Burning stove, this prevents the incinerator of burner hearth coking from including: burn fire grate；Body of heater, fire grate is upper and lower with burning
It is correspondingly arranged, the both sides furnace wall of body of heater is provided with bellows；Auxiliary burner, is arranged at body of heater both sides furnace wall
Dryer section on；Adherent airduct, enters in the burner hearth of body of heater through bellows, neat with the rear arch position in burner hearth
Flat, adherent airduct is provided with regulation valve；Beat burnt hole, be arranged on the both sides furnace wall outside body of heater, adherent
Airduct is correspondingly arranged up and down with beating burnt hole；Cooling water returns spout, is correspondingly arranged about burnt hole with beating.
Wherein, the bottom burning fire grate is connected with blower fan.
Wherein, prevent the incinerator of burner hearth coking from farther including feeding hopper, burn the import department of fire grate
It is connected with feeding hopper.
Wherein, it is provided with charging propeller between feeding hopper and burning fire grate.
Wherein, burn fire grate, body of heater and charging propeller to may be contained within support.
Wherein, cooling water is returned spout and is connected with time spraying equipment by pipeline.
Implement the embodiment of the present invention, have the advantages that the rubbish preventing burner hearth coking of the present invention burns
Burn stove and in burner hearth, blow cooling wind by arranging adherent airduct, and auxiliary burner is installed and offers cooling
Water returns spout, thus reduces fire box temperature, effectively controls the generation of coking, the both sides outside this external burner hearth
Offer on furnace wall and beat burnt hole, can carry out beating Jiao in real time in incinerator runs, prevent its further coking from deteriorating.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to enforcement
In example or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, describe below
In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the incinerator preventing burner hearth coking that the present invention provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
