Abstract
The invention discloses a device and method for garbage incineration. The device comprises an incinerator and a storage bin arranged above the incinerator. A lower bin door is arranged between the storage bin and the incinerator, the connection and disconnection of the storage bin and the incinerator are achieved through the opening and closing of the lower bin door, a gas-liquid separating device is arranged between the incinerator and an exhaust combustion chamber, air coming out of the incinerator reaches the exhaust combustion chamber through the gas-liquid separating device, and the exhaust combustion chamber is provided with an exhaust discharging port. First garbage is stacked in the storage bin to be stored; when the feeding to a hearth is needed, the lower bin door at the bottom of the storage bin is opened, the garbage falls into the hearth of the incinerator and slowly burns in the hearth, a gas-liquid mixture that has a certain temperature and is generated in the combustion process enters the gas-liquid separating device, gas having undergone gas-liquid separation is treated through the exhaust combustion chamber and then reaches the standard and is discharged.
Description
Technical field
The present invention relates to a kind of refuse disposal installation, particularly a kind of garbage combustion device and incinerating method.
Background technology
Current house refuse mainly adopts landfill or burning disposal, and doctor is useless, and rubbish mainly adopts burning disposal.Conventional garbage, when carrying out burning disposal, due to Processes and apparatus, is difficult to the discharge standard reaching tail gas, easily causes secondary pollution, and garbage disposal cost is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of secondary pollution that is not easy to cause be provided, tail gas energy qualified discharge a kind of garbage combustion device.
The present invention also aims to provide a kind of garbage incineration method.
A kind of garbage combustion device, include incinerator, be arranged on the storage bin above incinerator, lower door is provided with between storage bin and incinerator, conducting and the closedown of storage bin and incinerator is realized by the switch of lower door, be provided with gas-liquid separation device between incinerator and exhaust gas combustion chamber, incinerator air out arrives exhaust gas combustion chamber through gas-liquid separation device, and exhaust gas combustion chamber is provided with exhaust port.
Garbage combustion device of the present invention, first rubbish heap is entered storage bin to deposit, when burner hearth needs charging, bottom storage bin, lower door is opened, in the burner hearth that rubbish falls in incinerator and smoulder in burner hearth, the gas-liquid mixture with uniform temperature that combustion process produces enters gas-liquid separation device, and the gas after gas-liquid separation, after exhaust gas combustion chamber process, reaches qualified discharge.
Storage bin is provided with air extractor.Storage bin is provided with upper cover and lower door, the bleeding point of air extractor be located at storage bin side or on cover, charging at present door is closed, upper cover opens front air extractor work, and after air extractor work certain hour, upper cover is opened, add handled thing, upper cover covers rear lower door and opens to incinerator feed supplement.
Outside storage bin, arrange air extractor, first bleed to storage bin before the blowing of upper cover unlatching each time, so just the tail gas that can reduce in storage bin is discharged in air.
Incinerator is provided with make up air unit, and make up air unit is supplement air according to the temperature conditions in incinerator.
Incinerator make up air unit of the present invention changes incinerator in the past and replenishes air-breathing mode constantly, change timing into supplement, such raising rubbish is in the burning time of incinerator, to make the tail gas containing dioxin have enough time of staying and sufficiently high temperature in heating system, allow the abundant cracking of dioxin in tail gas.
Described make up air unit includes temperature sensor and blower fan.
When temperature sensor detects that in burner hearth, temperature is too low, the blower fan work outside burner hearth, supplements appropriate air, and burner hearth flame raises, and temperature raises.
Be furnished with water pipe in the upper furnace of incinerator, in water pipe, pass into cold water.
Water pipe is set in the upper furnace of incinerator, heat that burner hearth produces can be made full use of like this, the cold water in heating pipe, so namely can reduce inboard wall of burner hearth temperature, the heat of Absorbable rod Refuse Incineration Process generation again.
Described gas-liquid separation device or reducing suddenly flow velocity for adopting, reducing temperature manner and complete, or is completed by cyclonic separation mode.
Cyclonic separation is arranged on upper furnace, the cyclonic separation course of work is: the tail gas that Refuse Incineration Process is discharged enters conical shell along up big and down small conical shell madial wall, the dividing plate be rotated down is provided with in cylindrical shell, tail gas is along dividing plate and baffle contacts, small molten in tail gas is made to stick on dividing plate, gas enters exhaust gas combustion chamber toward rising, and aqueous material down flow in centralized collection device, realizes gas-liquid separation.Adopt the method that reduces suddenly of gas flow rate, the comparatively large or particle of density is directly declined, and realize gas-liquid separation, these 2 modes by structure embody; Gas-liquid separation device directly contacts with air, makes the quick desuperheat of tail gas without gas-liquid separation, speed up gas and liquid separating effect.
A kind of garbage incineration method, first sends rubbish into storage bin, then enters incinerator by storage bin, and the gas after incinerator burning enters after exhaust gas combustion chamber carries out second-time burning and enters in the air after gas-liquid separation.
This garbage incineration method, due to the gas that incinerator is produced carry out gas-liquid separation after enter exhaust gas combustion chamber again and burn, Refuse Incineration Process is produced be separated containing small molten in the gas of small molten, make gas no longer produce new dioxin in second-time burning process, thus alleviate the treating capacity of dioxin in tail gas heating system.
The burning of rubbish in incinerator is the burning of slow formula, and it is supplement air according to the temperature conditions in incinerator.
Rubbish to be contained in burner hearth and smoulder in burner hearth, can improve the adequacy of incineration firing.
Step of the present invention also comprises bleeds before to incinerator feed to storage bin.
Bleed before storage bin feed, first bleed to storage bin before the blowing of upper cover unlatching each time, so just the tail gas that can reduce in storage bin is discharged in air.
Described gas-liquid separation or employing reduce suddenly flow velocity, reduction temperature manner completes, or are completed by cyclonic separation mode.
In sum, the present invention's following advantage compared to existing technology:
Garbage combustion device of the present invention and garbage incineration method, due to
1. increase gas-liquid separation device, thus reduce vent gas treatment workload, make tail gas qualified discharge;
2. increase air extractor at storage bin, the tail gas that can reduce in storage bin is discharged in air;
3, upper furnace is furnished with cooling water pipe, namely can reduce inboard wall of burner hearth temperature, can make full use of again the heat that Refuse Incineration Process produces.
4, incinerator adopts smoulder mode, has enough time of staying and sufficiently high temperature containing dioxin in tail gas heating system, allows the abundant cracking of dioxin in tail gas.Arrive qualified discharge.
