Abstract
A garbage burning wind supply system comprises the number one and the second wind system for furnace wind supply, from smoke preheat to draw air through a wind pipe to the bottom of the furnace, a set of wind door on the wind chamber adjusted by the generator driven adjusting lever. The second wind system is the second heat wind pipe connected to the second cold wind pipe and the second heat wind pipe output connected to the second wind to the furnace through the channel. Trough the first wind system using single adjustment to each wind chamber, it can adjust the fuel change to each wind chamber, setting the fuel burning at certain stage to improve burning efficiency. Due to the cold wind inlet added, it makes it possible to switch the adjustment of cold and hot wind, prevent overheating, solving the garbage settling at various heat value.
Description
Technical field
The present invention relates to the incinerator in a kind of energy environment protection equipment, relate in particular to a kind of wind system of domestic waste incineration.It can be used for burning low heat value, high-moisture especially, without the domestic garbage burning electricity generation of letter sorting.
Background technology
Along with modern production development and urban population increase and level of consumption raising, the garbage environment pollution of generation causes social effects of pollution, causes the attention of various countries already.At present, the processing method of domestic waste has two big class kinds promptly to burn and sanitary landfills, and it oozes the many again polluted underground waters of drop liquid to the latter because of taking a large amount of soils, and landfill yard has caused the secondary pollution surrounding enviroment again.The external incineration treatment of garbage that adopts has mostly realized minimizing, innoxious, resource purpose.The starting of China incineration treatment of garbage soon, garbage combustion device mainly contains three kinds: i.e. mechanical kiln grate furnace, Circulation fluidized-bed furnace and thermal decomposition furnace.Thermal decomposition furnace is the incinerator of domestic firm exploitation, and it has two kinds of forms, the one, and horizontal, the disposal of refuse amount was 150t/d in maximum day, the 2nd, the vertical rotating type, the design maximum throughput is 100t/d.The vertical rotating thermal decomposition furnace especially contains the domestic waste that moisture is big, calorific value is on the low side because of a series of problems such as its device systems, does not all arrive the specified treating capacity of design as yet safely and steadly.Chinese patent 02111455.2 discloses a kind of domestic waste incineration.It contains body of heater, batcher, the fire grate of being with hopper, is positioned at air compartment, mucking machine under the fire grate, wherein fire grate segment contain be cemented in the stator on the body of heater and be spaced between the two adjacent stators of front and back and with move back and forth the activity template that rod member is connected, it is characterized in that: fire grate is divided into two sections of leading portion and back segments along the rubbish traffic direction, leading portion near hopper is that downward-sloping inverse-push fire grate, back segment is forwards formula fire grate, and is provided with the drop of certain altitude at the joining place of front and rear sections fire grate.Its weak point, the one,, the primary air system of required oxygen amount when air compartment enters burner hearth fuel combustion is provided under fire grate, former design is that the air door adjusting rod of four air compartments connects together, damper aperture simultaneously, can not adjust each air compartment separately, the air quantity of each air compartment is regulated in variation that can not based on fuel, and fuel can not well be burnt in presumptive area.Even when refuse moisture is low, rubbish on first air compartment just can fire burns, greatly reduce efficiency of combustion.The 2nd,, spray at a high speed burner hearth the disturbance flue gas and the secondary air system of requisite oxygen amount when burning is provided effectively, former design has only hot blast, when the garbage fuel calorific value was high, high temperature secondary wind sprayed into burner hearth, easily overtemperature, influence boiler excess load and safe operation, can not well guarantee the treating capacity of rubbish.
Summary of the invention
The technical problem to be solved in the present invention is, for the wind system that remedies the conventional garbage incinerator is regulated unreasonable, the weak point that causes the treating capacity aspect of firing efficiency, safe operation, rubbish, and provide a kind of adaptation high-moisture, low heat value consumer waste incineration, the wind system of the incinerator that the treating capacity of safe operation, efficiency of combustion height, rubbish is big, simple in structure.
The present invention solves the problems of the technologies described above to adopt following technical scheme: a kind of wind system of incinerator comprises to the primary air system of fire grate air feed with to the secondary air system of burner hearth air feed; It is characterized in that: described primary air system is to draw hot-air enters the fire grate bottom by airduct one group of air compartment in the flue gas air preheater from the 4th flue; One group of air door is set on the air compartment, and air door is regulated aperture by motor-driven air door adjusting rod respectively.
Described secondary air system, be from steam type airheater, to draw hot-air, enter the secondary hot-air pipe that is provided with the hot blast damper, secondary hot-air Guan Shangzai is connected with the secondary cool air hose of secondary cold wind damper, enters burner hearth by pipeline after the outlet of secondary hot-air pipe connects overfire air fan.
The hot blast damper is automatically controlled, and the cold wind damper is automatically controlled, and is electrically connected central controller respectively.
Good effect of the present invention is because the primary air system employing can be regulated separately to each air compartment of fire grate air feed, can not have influence on other air compartments.Variation that so just can based on fuel is carried out air quantity respectively to each air compartment and is regulated, and fuel is burnt at predefined phase, has improved efficiency of combustion.Because secondary air system adopts at the overfire air fan inlet and installs a cold wind import additional, makes hot and cold wind energy switch adjusting enough at any time, prevents overtemperature, influences boiler excess load and safe operation, the garbage treatment quantity problem when having solved different refuse thermal value.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
