Description

A kind of waste incinerator primary air intake pipe

Technical field

The utility model is related to a kind of waste incinerator air intake equipments more particularly to a kind of waste incinerator First air to enter the wind Pipe.

Background technology

The core that fire grate is garbage combustion device is burned, function is that support and conveying are used as in the combustion process of rubbish Equipment.Rubbish is pushed on incinerator, and under the First air effect by preheating, realizes refuse moisture rapid evaporation, rubbish Rubbish continues heat absorption and is warming up to flammable matter and oxygen generation vigorous reaction.With the feeding of Secondary Air, rubbish burns production on fire grate Raw volatilization is decomposed and burnt away, and the lime-ash generated after waste incineration falls into deslagging by the lime-ash discharge port of fire grate end and sets It is standby.

Rubbish burns on fire grate is a recombination process, including it is multiple it is interrelated, interact and forward lap Process is divided into dryer section, thermal decomposition section, gasification section, burning and burning segment along siege length direction.It is whole along length to burn fire grate Direction is divided into multiple burning units, and each burning unit is made of multiple slip fire grate segments, travelling grate piece and fixed grate film. It sliding fire grate segment and generates horizontal reciprocating motion, rubbish bed is promoted to be moved to slag-drip opening, travelling grate piece generates flip-flop movement, These fire grate segments generate up and down motion in action, realize the effect of poking fire of rubbish.

The lower part of every section of fire grate is connected to leakage ash bucket, but is mutually isolated, and forms the chamber of autonomous closure.In every section of leakage ash bucket Side wall once from the air hose be sent by wind blast pipe, First air.The inlet of each air compartment is equipped with damper under fire grate, adjusts Its aperture is sent into the primary air flow of each air compartment to control.Every section of fire grate is different according to residing fire grate position, the First air of feeding Amount is also different, by adjusting air quantity, so as to meet the required air quantity in each combustion zone, is well matched with air-supply burned Journey, to improve efficiency of combustion.

Existing blast pipe is simply linked into leakage ash bucket side wall without extending into internal chamber, influences combustion air once Degree of filling in air compartment causes combustion air that cannot enter the incineration firing bed of material on fire grate uniformly across air compartment, i.e. flame is uneven It is distributed in evenly on stoker surface, the rubbish on fire grate is caused not burn and just falls directly into residue extraction mechanism, reduces fire grate segment Service life.

Utility model content

The shortcomings that in order to overcome the prior art and deficiency, the utility model provide a kind of waste incinerator First air air inlet dress Put, including leakage ash bucket and blast pipe, it is characterized in that, the blast pipe is stretched into horizontal direction in leakage ash bucket inside, it is described into Ventilation hole is set under air hose horizontal direction on half side tube body, and First air from the ventilation hole after the blast pipe through entering leakage Ash bucket.First air is evenly distributed after air hose is discharged in air compartment, and combustion air enters rubbish on fire grate uniformly across air compartment Burn the bed of material, is distributed on stoker surface with making even flame, improves the service life of fire grate segment, improves burning for rubbish Rate.

The utility model solves the technical solution that technical problem is proposed, a kind of waste incinerator First air air inlet dress It puts, including leakage ash bucket and blast pipe, the leakage ash bucket is disposed on the downside of fire grate, and the blast pipe is arranged on the leakage ash bucket Lower part, it is characterized in that, the blast pipe is stretched into horizontal direction in leakage ash bucket inside, the blast pipe in circular tube structure and Through setting ventilation hole on the half side tube body below pipe axis horizontal face, First air enters leakage through the blast pipe from the ventilation hole Fire grate is risen to after ash bucket.

The utility model preferred embodiment, the ventilation hole are a big notch.

The utility model preferred embodiment, the ventilation hole are equally distributed circular hole.

The utility model preferred embodiment, end face of the blast pipe inside leakage ash bucket is inclined-plane.

The utility model is prompted, and ventilation hole is arranged on tube body half side under blast pipe horizontal direction, it is therefore an objective to be made once Wind not only can from ventilation hole by, but also can prevent the lime-ash fallen down from fire grate from ventilation hole enter ventilation duct so as to Block.

The beneficial effects of the utility model：The utility model proposes a kind of waste incinerator First air air-intake device, by It stretches into leakage ash bucket in the blast pipe, and is laid on tube body half side under the blast pipe horizontal direction in horizontal direction Ventilation hole is put, First air is evenly distributed after air hose is discharged in air compartment, and combustion air enters uniformly across air compartment on fire grate The incineration firing bed of material is distributed on stoker surface with making even flame, is improved the service life of fire grate segment, is improved rubbish Burnout rate.
