Description
Technical field
The utility model belongs to thermal power and field of environment protection, and in particular to a kind of screen residue of waste burning boiler.
Background technology
The life refuse processing method of current domestic main flow mainly has landfill, burning electricity generation and diversification processing.It is conventional
Landfill, incineration treatment method drawback all be present.For example, landfill does not only take up large amount of land resources, and easily cause serious
Secondary pollution；For burning electricity generation, its cost of investment is high, and part reusable edible material directly destroys by fire and meeting in rubbish
Cause the wasting of resources.Therefore, refuse classification diversification processing can reduce garbage treatment quantity, save the energy, reduce environmental pollution, and become
Waste be changed into values, has society, economic, three aspect benefits of ecology.
Rubbish diversification processing is to be sorted house refuse, utilizes a systems such as rotary screen, weight separator box, magnetic separator
Row equipment is sorted house refuse, sub-elects screenings and oversize.Screenings mainly includes silt, dregs fragment of brick, gold
The mode such as category, perishables etc., generally use brickmaking, compost, metal recovery recycles；And oversize mainly includes plastics, skin
The high heating value rubbish such as leather, textile, typically by burning electricity generation integrated treatment, but because oversize has calorific value height, ash fusion point
It is low, fugitive constituent is high, the characteristics of easily bonding, the easy coking dust stratification on heating surface, therefore common garbage burning boiler is affected by it,
Run time shortens, and disposal ability declines, and has a strong impact on garbage treatment efficiency.Therefore, it is a kind of new and effective there is an urgent need to develop
Handle the burning boiler of screen residue of waste.
Utility model content
The technical problem that the utility model solves is to provide a kind of screen residue of waste burning boiler.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of screen residue of waste burning boiler, including steelframe, fire grate, furnace chamber, wherein furnace chamber are installed on steelframe, furnace chamber point
Into combustion chamber, burning chamber, three flue three parts, furnace chamber and down-comer, top connecting tube and drum composition circulation loop, the stove
Row is arranged on below furnace chamber, the furnace chamber outlet connection back-end ductwork, and fly ash carry device, institute are set below the back-end ductwork
State fire grate afterbody and mucking machine is housed.Arrangement economizer in the back-end ductwork；It is disposed with from the bottom up in three flue
First evaporator and superheater；The evaporator of burning chamber's lower disposed second, it is characterised in that the combustion chamber top is equipped with J
Type water-cooling screen, the combustion chamber bottom are provided with the front and rear arch of water cooling, the burning chamber, three flue lower disposed water cooling ash buckets.
Further, the J-type water-cooling screen uses the micro- welding technology of low temperature, and melting welding one layer of nickel chromium triangle in surface adds the alloy of rare earth
Material.
Further, the J-type water-cooling screen does not use independent circulation circuit, and its import is directly connected with down-comer, outlet
It is connected with top connecting tube.
Further, the combustion chamber water-cooling wall uses steel alloy thick-walled pipe, and its wall thickness is 6mm.
Further, the fire grate uses water-cooling reciprocation stove grate.
Further, the first evaporator tube bank inlet and outlet are directly connected with water-cooling wall；Second evaporator has
Independent circulation circuit.
Further, fly ash carry device dust inlet is located above mucking machine at 2 meters.
Further, the mucking machine is positioned over below zero meter of layer.
The beneficial effects of the utility model are as follows：
1. because screen residue of waste calorific value is high, screen residue of waste burning boiler used in furnace chamber part before and after water cooling arch and
Water cooling ash bucket structure, water wall surface product is increased, prevents its coking.
2. being equipped with J-type water-cooling screen on combustion chamber top, the structure makes full use of boiler space, adds heating surface area.Adopt
With the micro- welding technology of low temperature, on surface, one layer of nickel chromium triangle of melting welding adds the alloy material of rare earth, can extend water-cooling screen service life.J-type
Water-cooling screen does not use independent circulation circuit, and its import is directly connected with down-comer, and outlet is connected with top connecting tube, can simplify
Pipeline, drum perforate is reduced, be particularly suitable for use in old boiler improvement.
3. because high temperature corrosion is serious in combustion chamber, combustion chamber water-cooling wall uses steel alloy material and wall thickness is 6mm, can
Extend water screen tube service life.
4. setting the first evaporator and the second evaporator in three flues, burning chamber bottom respectively, the confined space is made full use of,
Effectively increase heating surface area, it is compact-sized, easy for installation.
5. for the features such as screen residue of waste calorific value is high, ash fusion point is low, fugitive constituent is high, easily cohesive, therefore fire grate uses water
Cold reciprocal grate, it can effectively avoid fire grate coking situation.
6. because the fly ash granule that economizer bottom fly ash carry device is collected is smaller, flying dust is such as routed directly to rear arch
Place, is easily taken away by flue gas, can not descend ash.Therefore, fly ash carry device dust inlet is arranged in above mucking machine at 2 meters.If
Dust inlet position is too low, and steam easily makes grey bonding in mucking machine, the ash so as under the influence of.
7. mucking machine is positioned over below zero meter of layer, boiler whole height can be reduced, while height between ensureing to slag tap,
Reduce civil engineering, cost of investment.
In summary, after using said structure of the present utility model, energy efficient process screen residue of waste, its high heating value is utilized
Characteristic combustion power generation, the face that keeps from heat, fire grate coking dust stratification, extend run time.
