Description
Technical field
The utility model is related to a kind of burning domestic waste and steam is generated in steam supply, the gas cleaning to generate electricity
Put formula garbage burning boiler.
Background technology
At present, domestic waste is handled using burning method, is widely applied in China.With governments at all levels pair
The pay attention to day by day of environmental protection, the pollutant emission requirement after waste incineration are increasingly stringent.Therefore, how safe, reliable, efficient,
Waste incineration is carried out environmentally friendlyly, and efficiently controls the discharge of pollutant, is already the newest problem of current garbage incineration technology.
In order to which the innoxious of domestic rubbish disposal, minimizing, recycling is better achieved, gas cleaning processing cost is effectively controlled, and
Meet harsh environment protection emission requirement, therefore develop a kind of built-in garbage burning boiler of gas cleaning for the first time at home, that is, exist
Boiler internal sets efficient flue gas purification system, it is ensured that boiler exhaust gas can direct qualified discharge, without carrying out purified treatment again.
Further, since the gas cleaning efficiency of high efficiency boiler, the flue gas in back-end ductwork is very clean, without low-temperature corrosion and dust stratification
Etc. factors influence, can more arrange the back-end surfaces such as economizer, smoke air preheater, the exhaust gas temperature of boiler can be by leading to
Normal 200 °C or so are down to about 130 °C, and system absorbs the heat content of about 70 °C of flue gases, therefore, pot described in the utility model more
Stove not only can be also greatly reduced flue gas loss, be significantly improved boiler thermal efficiency with purifying smoke.
Utility model content
The purpose of this utility model is to provide a kind of built-in garbage burning boilers of gas cleaning.
Realize above-mentioned purpose, the utility model adopts the following technical solution, a kind of built-in waste incineration pot of gas cleaning
Stove includes furnace chamber, environmentally friendly flue, toilet and back-end ductwork.It is characterized in that：The furnace chamber is by burner hearth, burning chamber and three
Flue forms, and environmentally friendly flue, toilet and back-end ductwork are set gradually after furnace chamber.
Further set of the utility model be：The burner hearth is equipped with denitrification apparatus；In the burning chamber waterpower is set to remove
Grey device；Arrangement evaporating heating surface, superheater in three flue；The environmental protection flue is equipped with dry method superfine powder injection apparatus；Institute
It states and catalyst pottery fine chimney filter is set in toilet；Arrangement smoke air preheater, economizer in the back-end ductwork.
Further set of the utility model be：The denitrification apparatus sets several layers of denitration spout in burner hearth.
By using said program, the utility model has the following advantages：
1st, since reaction temperature window optimal denitration in the stove SNCR is 800 ~ 1000 °C, therefore filled in burner hearth equipped with SNCR denitration
It puts, several layers of denitration spout is set in burner hearth, to select appropriate spout in real time according to chamber flue gas temperature, it is ensured that denitration is imitated
Rate.
The 2nd, hydraulic(-ash) sluicing device is set in burning chamber.When implementing ash disposal, the blowing pipe of crispation type is extended in burning chamber, is aligned
Minimal amount of water is sprayed at coking/dust stratification, droplet after encountering coke button bursts, comes off at once, with this, quickly and efficiently removes water
The coking of cold wall surface and dust stratification.
3rd, evaporating heating surface is arranged at three chimney intakes, the import smoke temperature of superheater can be effectively reduced, prevent superheater from going out
The problem of existing high temperature corrosion, and flue gas stream and retention flying dust can be effectively evenly distributed with to ash bucket.
4th, environmentally friendly flue is equipped with dry method superfine powder injection apparatus, by the sodium acid carbonate superfine powder of jet drying, make its with
Neutralization reaction occurs for the acidic materials in flue gas, achievees the purpose that depickling desulfurization with this.Due to the sodium acid carbonate superfine powder of penetrating
It touches in environmentally friendly flue after 300 °C ~ 400 °C of hot flue gas, sodium acid carbonate is quickly converted to sodium carbonate, and possesses it
Increase by 10 times of surface area at high proportion and porosity, the sodium carbonate of high surface area quickly and effectively with sour gas（HCl、SO2、
HF etc.）Generation neutralization reaction；Also, environmentally friendly flue has enough height, it can be ensured that neutralization reaction has the sufficient reaction time, therefore
The reaction efficiency of this dry-process deacidification desulfurization is higher.
The 5th, the fine chimney filter of catalyst pottery is set in toilet, i.e., by adding in catalyst in ceramic fiber tube（Catalyst）, together
It realizes filtering dust, accelerate catalytic elimination nitrogen oxides He the purpose of bioxin.The basic material of chimney filter is fine for superfine ceramics
Dimension, high porosity, heat safe characteristic, it can be achieved that under high temperature dust ＜ 5mg/Nm3 dust collection target.Ceramic fibre chimney filter is straight
It connects on orifice plate, excellent rigid structure, it can be ensured that higher filter efficiency and performance that is long-acting, stablizing.And
And be distributed in by catalyst on chimney filter, effectively increase the contact area of flue gas and catalyst, make gas residence time and denitration anti-
Efficiency is answered to maximize.Moreover, , bioxin and oxygen reaction under the action of catalytic component based on vanadium, are broken down into CO2、H2O, HCl etc.
Innocuous substance is discharged.For this purpose, the group technology of SNCR+ dry-process deacidifications desulfurization+fine chimney filter of catalyst pottery, it can be ensured that toilet exit
Flue gas reaches clean emission.
6th, arrange smoke air preheater in back-end ductwork, may replace conventional arrangement of steam type airheater.Steam is empty
Air preheater is to be exchanged heat by extracting drum saturated vapor with air, for this purpose, smoke air preheater substitutes steam air
The setting of preheater, can reduce the extraction of drum saturated vapor, thus effectively increase the evaporation capacity of boiler.
