Description
(1) technical field:
The invention patent discloses a kind of domestic sludge incinerator group, belongs to machine by International Patent Classification (IPC) (IPC) division
Tool engineering；Illumination；Heating；Weapon；Explosion portion, illumination；Heat branch, combustion apparatus；Combustion method major class, incinerator；Waste
Destroy group, light or moveable incinerator group class field by fire.
(2) background technique:
Currently, existing or once burning facility of some about domestic sludge, is to be provided with solid combustion room and gas combustion
Room is burnt, to prevent burning from having some setbacks, is additionally provided with combustion-supporting system, sludge is produced in primary zone's internal oxidition, pyrolysis, burning, burning
Raw flue gas enters secondary combustion chamber, and high temperature incinerates again, stops working during sludge incineration as burnt, can pass through spray
Blowing combustion adjuvant (generally coal dust or oils).The disadvantage is that: in sludge incineration, sludge is because of poor air permeability caused by reunion, burning
Unevenly, if sludge water content is excessively high, lead to combustion instability, then need to be blown a large amount of combustion adjuvants；Meanwhile pole after sludge incineration
Easy dusting, the flue gas after combustion air burning carry a large amount of dust secretly, increase burden for rear end fume treatment.Existing sludge incineration
Furnace though having more improvement or adjustment, but still burns poor air permeability without solving high moisture sluge, needs to add combustion adjuvant, tail
Technical problem in gas containing a large amount of dust, combustion furnace structure complexity.
(3) summary of the invention:
To solve existing sludge incinerator poor air permeability, need to add that combustion adjuvant, tail gas dust amount is big, combustion furnace structure is complicated
The technical issues of, the present invention provides a kind of domestic sludge incinerator groups.
The main distinction of domestic sludge incinerator group and existing domestic sludge incinerator in the present invention is in incinerator, air distribution
Change is made that in system:
The first, incinerator group moves circulating for multistage, and single incinerator motion profile is fixed in orbit, track point
Upper and lower level, incinerator since the igniting of lower layer one end, move in entire burning process and are transferred to upper layer after a certain period of time,
Will burn complete when, bottom burning as new burning furnace igniting heat source, after the completion of igniting, this incinerator
Burning is completed, and lower layer's slag dumping, stone are recycled to, and prepares igniting.
The second, incinerator air distribution mode is using negative-pressure air fan from incinerator bottom drawing, and fresh air is from burning furnace roof
Portion enters, and sludge is also to burn gradually downward since top.
Third, blowing system are that multiple groups are independent, need to provide different negative pressure and air quantity according in different time periods, accurately
Control combustion process.
Compared with existing domestic sludge incinerator, using design scheme of the invention, following technical effect can achieve:
First, due to being designed as multistage removable frame in the technical solution of domestic sludge incinerator group of the invention, transport
Row track is divided into upper and lower level, and when burning is near completion, the high temperature sludge of base burning is burnt single incinerator as new
The igniting heat source of furnace is burnt, so without expending the igniting energy for a long time.
Second, since domestic sludge incinerator group air distribution mode of the invention is to be taken out using negative-pressure air fan from incinerator bottom
Wind, fresh air enter from top, and sludge incineration is also when burning waste gas passes through the sludge bed of material, to burn since top
Heat entrained by exhaust gas plays the role of drying sludge, meanwhile, lower layer's sludge water content is higher, when can adhere to exhaust gas discharge
The dust of carrying solves the problems, such as that dust content is high in common sludge tail gas from incinerator.
Third, since the blowing system of domestic sludge incinerator group of the invention is multiple groups independence air distribution, at the initial stage of ignition
Higher negative pressure and biggish air quantity are needed, higher negative pressure and lesser air quantity are then needed after kindling, is burned to mid-term, is needed
Negative pressure and air quantity it is all smaller, when i.e. by burning-out, and need biggish air quantity and lower negative pressure, multiple groups independence air distribution
Mode keeps air distribution controllable, energy-saving, accurate control of burning, and solves that distribution wind unfair is even, and air quantity cannot distribute as needed, combustion
It burns and controls bad problem.
Domestic sludge incinerator group of the invention is suitable for burning moisture content in the domestic sludge of 15-58%.The life is dirty
The production of mud incinerator each unit is simple, and cost is relatively low, and it is convenient to be applicable in, easy to spread.
(4) Detailed description of the invention
Fig. 1 provides the structural schematic diagram of the domestic sludge incinerator group of the invention patent.
(5) specific embodiment
