Description

Biomass fuel counter-burning type oven
Technical field
The utility model belongs to Baking out equipment technical field, is specifically related to a kind of biomass fuel counter-burning type oven.
Background technology
At present, roasting plant great majority are still so that conventional mineral mass-energy source---coal is for main fuel, now develop and variously achieve some beneficial effects using solar energy, air energy, electric energy as the baking equipment for preparatory treatment of tobacco of main heating source, but there is system architecture complexity, difficult in maintenance, high in cost of production problem.What the heating furnace of existing intensive baking room adopted is the design of single grate, and coal-fired in body of heater after primary combustion, a large amount of combustible is with fume emission, unburnt slag of being used as abandons, coal-fired utilization rate is low, and the thermal efficiency is not high, also pollutes environment while causing the wasting of resources.Under the environment that resource is increasingly in short supply, improve coal utilizaton rate, the consumption reducing coal and Looking For Substitutions Of Oil and seem particularly important and urgent.
Utility model content
The purpose of this utility model proposes a kind of burning more fully and effective biomass fuel counter-burning type oven improving the thermal efficiency.
The technical solution of the utility model is achieved in that a kind of biomass fuel counter-burning type oven, comprise combustion furnace and heat exchanger, the burner hearth of described combustion furnace is closed, the first grate is provided with and this burner hearth is divided into upper combustion chamber, lower combustion chamber and dust storage chamber by the second grate in this burner hearth, the gap length of this second grate is less than the gap length of the first grate, this upper combustion chamber is connected with the first combustion-supporting airduct and fuel-supply pipe, this dust storage chamber is connected with the second combustion-supporting airduct, and this lower combustion chamber is connected with described heat exchanger by flue gas air channel.
Upper and lower two combustion chambers are formed by adopting upper rare lower close double-deck grate, during burning, fuel is upper, flame is downward, ashes Automatic-falling is in dust storage chamber, the unburnt fuel of upper combustion chamber can fall into lower combustion chamber, Secondary Air is coordinated to carry out Thorough combustion, make redox district have enough oxygen supplies, utilize the principle that thermal current rises, fuel is carried out preheating by the thermal current that part rises, unnecessary moisture is evaporated, make fuel meat rapid temperature increases to burning-point, whole combustion process is carried out smoothly, and fuel combustion is complete.
The utility model is using abundant renewable resource---and stalk is as baking fuel, agricultural production is produced a large amount of crop stalks as fuel, gather materials on the spot, abundance, be used for replacing fire coal, the environmental pollution that effective solution crop straw burning brings, can also reach resource recycling, improve farmers' income.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Biomass fuel counter-burning type oven as shown in FIG. 1 to 3, comprise combustion furnace 1 and heat exchanger 2, the burner hearth of described combustion furnace 1 is closed, its inside arranges refractory lining 12, the first grate 5 is provided with and this burner hearth is divided into upper combustion chamber 4 by the second grate 7 in this burner hearth, lower combustion chamber 6 and dust storage chamber 8, the gap length d2 of this second grate is less than the gap length d1 of the first grate, this upper combustion chamber 4 is connected with the first combustion-supporting airduct 9 and fuel-supply pipe 10, this dust storage chamber 8 is connected with the second combustion-supporting airduct 11, this lower combustion chamber 6 is connected with described heat exchanger 2 by flue gas air channel 3.
For convenience of operation and maintenance, described upper combustion chamber 4, lower combustion chamber 6 and dust storage chamber 8 are equipped with fire door.
Shown heat exchanger 2 is prior art, comprises heat exchanger tube 21 and chimney 22, arranges radiating fin with increasing heat radiation area outside this heat exchanger tube 21.
First combustion-supporting airduct 9 is connected with blower fan respectively with the second combustion-supporting airduct 11, and fuel-supply pipe 10 is connected with automatic feeding system.
The operation principle of this biomass fuel counter-burning type oven is as follows with the course of work: section material biomass fuel stalk cutting machine guillotine cutting being become 2 ~ 4 centimetres, loads automatic feeding system, according to barn humiture demand modeling feed quantity and fan delivery.On the first grate 5 of upper combustion chamber 4, stalk is paved with before igniting, at the second grate 7 upper berth part stalk of lower combustion chamber 6, light the stalk in lower combustion chamber 6, the stalk ignited after straw burning in upper combustion chamber 4, start blower fan, combustion-supporting gas is entered the top of upper combustion chamber 4 by the first combustion-supporting airduct 9 and is entered the bottom of lower combustion chamber 6 by the second combustion-supporting airduct 11, stalk in combustion-supporting upper combustion chamber 4 completes primary combustion, the volatile ingredient that upper combustion chamber 4 burning produces, fuel gas and high-temperature flue gas are blown into lower combustion chamber 6 under the active force of combustion-supporting gas, and enter bottom combustion-supporting gas effect under form second-time burning.Heat exchanger 1 is entered through flue gas air channel 3 together with the high-temperature flue gas that upper combustion chamber 4 stalk burnt incompletely and the high-temperature flue gas produced after volatile ingredient second-time burning and upper combustion chamber 4 are accepted by lower combustion chamber 6, heated by heat exchanger tube 21 room air of heat exchanger 1, flue gas after heat exchange is discharged by chimney 22, and the ashes that burning is formed fall into the dust storage chamber 8 of bottom.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
