Description

Syllogic stoker incinerator

Technical field

The utility model relates to the environmental protection equipment field, is specifically related to incinerator.

Background technology

The technology of garbage disposal that extensively adopts at present is with incinerator, rubbish to be carried out burning disposal, the stoker incinerator is a kind of inverse-push incinerator of present technology maturation, rubbish overturns on fire grate, the burning degree is high, but the rubbish of China is because not doing classification when collecting processes, and complicated is easy to form coking during burning, cause coke button inside insufficient burnt, waste incineration is not thorough; The stoker incinerator only has an end formula fire grate at present, and the rubbish crushing of coking is more difficult.

The process of incineration treatment of garbage is divided into drying, burns, burns three processes, wherein dry run usually adopts is that the radiant heat of high-temperature flue gas, burner hearth side wall and furnace roof of reverse flow and the high temperature air convection current of sending into the fire grate below contact to dry rubbish, high temperature air can be supported the burning of rubbish on the one hand in burning with in burning process, to avoid because Cryogenic air is sent into incinerator on the other hand, cause the temperature difference in stove large, affect the efficient of incineration firing; High-temperature flue gas and the air at room temperature greater than 550 ℃ of normally the waste heat boiler of incinerator being discharged in prior art carry out thermal energy exchange through heat exchanger, and Cryogenic air is heated to send into behind 250 ℃ of left and right each process of fire grate below; Each process analysis procedure analysis according to rubbish on fire grate as can be known, the temperature of dry run is higher, it is faster that rubbish is dried, and provide better condition for two follow-up processes, but this process adds oxygen that the content of nitrogen in flue gas, oxygen compound is improved, and increases the difficulty that gas cleaning is processed, and is therefore necessary high temperature air for burning and the process that burns, be not the optimal selection of dry run, result of use is bad.

For the incinerator of continuous operation, the expense of at every turn again putting stove is higher in addition, is zero so require equipment failure rate, and the Hydraulic Station of continuous operation is prone to fault, the processing scheme that in the past adopted is the using and the reserved, namely prepares two Hydraulic Stations, causes equipment funds to drop into higher.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of syllogic stoker incinerator, can solve the problem that existing stoker incinerator rubbish coking causes burning not thoroughly, drying effect is bad and the equipment funds input is high.

The utility model is achieved through the following technical solutions:

Syllogic stoker incinerator, comprise the burning body of heater, be provided with stoker between the garbage inlet of described burning body of heater and ashes outlet, described stoker is connected with Hydraulic Station, described stoker below is provided with the preheated air pipe, described stoker comprises burning segment stoker, burning zone stoker, dryer section stoker, the import of described burning segment stoker is positioned at the outlet below of burning zone stoker, and the import of described burning zone stoker is positioned at the outlet below of dryer section stoker.

The further improvement of the utility model scheme is, the burning segment stoker is horizontally disposed with, and the import of described burning zone stoker and dryer section stoker is higher than the outlet-inclined impeller vane setting.

The further improvement of the utility model scheme is that burning zone stoker and dryer section stoker and horizontal plane angle are 20 ~ 30 °.

The further improvement of the utility model scheme is that the distance between the outlet of the outlet of the import of burning segment stoker and burning zone stoker and the import of burning zone stoker and dryer section stoker is 0.8 ~ 1.0 meter.

The further improvement of the utility model scheme is that the outlet of preheated air pipe is positioned at below the burning zone and burning segment of fire grate; Flue is provided with arm between waste heat boiler and heat exchanger, described arm outlet is positioned at below the dryer section stoker, and described arm is provided with high temperature draught fan.

The further improvement of the utility model scheme is, the fuel tank flowline of Hydraulic Station is communicated with first, second hydraulic power unit of parallel connection, the outlet one tunnel of described first, second hydraulic power unit is returned to fuel tank through overflow pipe, another road communicates through magnetic valve first, second solenoid directional control valve with parallel connection, and described first, second solenoid directional control valve also communicates with the oil return pipe of fuel tank and rodless cavity oil pipe, the rod chamber oil pipe of driving oil cylinder respectively.

The utility model advantage compared with prior art is:

One, adopt the syllogic stoker, there is the difference in height of 0.8 ~ 1 meter each section junction, and rubbish falls in the junction, more easily rolling and fragmentation, burning more thorough;

Two, deliver to dry run fire grate below with what waste heat boiler was discharged greater than 550 ℃ of high-temperature flue gas, the rubbish drying rate is faster, and for a combustion chamber of incinerator provides a large amount of heat energy, for the follow-up burning of rubbish, the process of burning have been created advantage; Reduced by 15% ~ 20% high temperature air demand, reduced simultaneously the content of dry run oxygen, reduced the generation of nitrogen, oxygen compound, for advantage has been created in gas cleaning.

Three, the parts that Hydraulic Station are prone to fault carry out Redundancy Design, have improved the processing speed when breaking down, and have reduced the equipment funds input, have saved cost, have increased the benefit of enterprise.
