Description

A kind of horizontal garbage burning boiler

Technical field

The invention belongs to and a kind ofly burn domestic waste and produce the horizontal garbage burning boiler that steam is used for steam supply, generating.

Background technology

Along with the Chinese society rapid development of economy, urbanization process is accelerated, and domestic waste increases sharply.How to deal carefully with rubbish and become the task of top priority.The development garbage burning boiler burns rubbish in boiler, and utilize the heat that burns to produce steam and be used for steam supply and generating, be garbage as resource, minimizing and innoxious optimal path, have good environmental benefit, social benefit and economic benefit.

At the rubbish characteristic of China, realize innoxious, the minimizing and the resource of garbage disposal, be the important topic of garbage burning boiler research and development.In order to burn the domestic waste of domestic low heat value, high moisture content, ash-rich better,, impel rubbish in time to catch fire and completing combustion with this so completely newly developed a kind of horizontal garbage burning boiler.

Summary of the invention

The present invention overcomes existing issue, and a kind of the guarantee timely drying of domestic waste of low heat value, high moisture content, ash-rich, the horizontal garbage burning boiler that catches fire, burns and burn are provided.

Realize above-mentioned purpose; the present invention adopts following technical scheme; a kind of horizontal garbage burning boiler; include steelframe; burner hearth; fire grate and slag tap and ash discharge equipment; wherein burner hearth is installed on the steelframe; fire grate is arranged on the bottom of burner hearth; slag tap and be arranged on the below of fire grate with ash discharge equipment; described fire grate is two sections reciprocating fire grates; described lower furnace portion and be positioned on the side wall of two sections reciprocating fire grates top auxiliary burner is installed; mounting points ignition combustor on the back wall of lower furnace portion; it is characterized in that: be disposed with the burning chamber that passes through successively for flue gas behind the described burner hearth; three flues and horizontal flue; the outlet of horizontal flue directly is connected with the neutralization reaction tower, is disposed with protection tube in the described horizontal flue; high temperature superheater; medium temperature overheater; low temperature superheater; evaporating heating surface and economizer.

By adopting such scheme, the present invention has following advantage:

1, boiler adopts horizontal layout, and the pipe of convection heating surfaces at different levels is vertical, and the flue gas cross-current is crossed convection heating surfaces at different levels, is convenient to deashing.

2, adopt two sections reciprocating fire grates.This kind fire grate can make rubbish overturn effectively, stir, and has comparatively ideal burning condition, can realize rubbish completing combustion.Simple backstepping or forwards fire grate are to the stirring of rubbish and stir lessly, occur the phenomenon that local rubbish is grilled thoroughly, local rubbish does not burn again easily.Two sections reciprocating fire grates that backstepping fire grate and forwards fire grate are combined, can make incineration firing thorough, have adapt to that thermal value range is wide, the Load Regulation ability is big, stable and reliable operation, sufficient combustion, characteristics such as workable, the domestic waste of China without letter sorting, low heat value, high moisture content, ash-rich is specially adapted to burn.

3, on two sections reciprocating fire grates, the burn flue gas that produces flow through successively burner hearth, burning chamber, three flues and horizontal flue of domestic waste, flue gas flow is long, abundant cooled flue gas, preventing influences the boiler heat absorption because of coking, flue gas through three flues after, the temperature that enters horizontal flue has been lower than ash fusion point, can avoid coking on convection heating surface.

4, arrange protection tube in the horizontal flue, can make smoke distribution even, allow the superheater thermally equivalent, can reduce the superheater input gas temperature simultaneously, avoid the superheater coking.

5, the horizontal flue outlet directly is connected with the neutralization reaction tower, and the framework and the boiler steelframe that support the neutralization reaction tower are connected as a single entity, and has not only saved steel, has also shortened the flue gas stroke, makes compact conformation, has saved the place.

The further setting of the present invention is: face arch and rear arch are arranged in the two sections reciprocating fire grate tops that are positioned at of described burner hearth, and arrange secondary wind respectively at forward and backward arch place; Described protection tube, high temperature superheater, medium temperature overheater, low temperature superheater, evaporating heating surface and economizer are all arranged along row; The junction of described economizer tube is arranged on the outer top of flue; Described high temperature superheater place is provided with shock-wave ash blowing device and ash removal equipment for flapping.

By adopting above-mentioned further technical scheme, the further advantage of the present invention is:

1, the adiabatic front and back arch structure of design makes full use of radiant heat rubbish is carried out preheating and drying, and simultaneously, arch sprays into secondary wind in front and back, strengthens the disturbance of flue gas, the fire stroke of prolong smoke, and the incineration firing effect is good, burnout rate is high.

2, high temperature superheater adopts shock-wave ash blowing and the ash disposal of vibration dust-cleaning dual mode, can more effectively remove coking and dust stratification.

3, the outer top of flue ways of connecting is adopted in the economizer tube, can guarantee welding quality, prevents that effectively the economizer tube from leaking, and easy access.

Below in conjunction with accompanying drawing the present invention is further described.
