Abstract
The utility model relates to combustion equipment, belonging to the technical field of heat supply equipment. A flue gas circulation backfiring device comprises a furnace shell; a chimney is mounted on the furnace shell; the furnace shell is internally divided into a combustion chamber and a flue gas chamber; the lower end of the combustion chamber is connected with a chain type grate; an air inlet is arranged on the side wall of the combustion chamber; a feed device is mounted at the lower end of the air inlet and comprises a hopper; the lower end of the hopper is connected with a feeder; a screw-in sheet is arranged in the feeder and goes forward while rotating under the drive of a motor; one side of the flue gas chamber is connected with a flue gas recoverer through a connection pipe; and the flue gas recoverer is connected with the combustion chamber through a connection pipe. In the flue gas circulation backfiring device provided by the utility model, the incomplete-combustion flue gas is subjected to secondary recovery and backfiring, and finally the fuel is sufficiently burnt; and thus relatively little toxic gas is contained in the discharged flue gas, and the operation cost of the enterprises is also reduced.
Description
Technical field
The utility model relates to combustion apparatus, belongs to the heating equipment technical field.
Background technology
The combustion apparatus that uses in the daily production all is to adopt coal to act as a fuel; Often include a large amount of unburneds particle completely in a large amount of dense smokes that this fuel produces in combustion process,, not only can influence environmental quality in case be diffused in the air; Also can influence the growth of flowers, plants and trees; And, influence daily production efficiency because the not enough composition of burning also causes thermal efficiency ratio lower easily.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and a kind of thermal efficiency height, sufficient combustion, the less flue gas recirculation back fire device of pollution are provided.
The utility model is realized through following technical scheme:
A kind of flue gas recirculation back fire device, its special character is to comprise furnace shell 1, and chimney 2 is installed on the furnace shell 1; Be divided into combustion chamber 12 and smoke chamber 13 in the furnace shell 1, the lower end of combustion chamber 12 is connected with chain furnace grate 6, and the sidewall of combustion chamber 12 is provided with air inlet 11; Air inlet 11 lower ends are equipped with feed arrangement, and feed arrangement comprises hopper 10, and hopper 10 lower ends are connected with feeder 8; Be provided with precession sheet 7 in the feeder 8; Precession sheet 7 advances through motor 9 driven in rotation, and a side of smoke chamber 13 is connected with flue gas recover 4 through taking over 3, and flue gas recover 4 passes through tube connector 5 and is connected with combustion chamber 12.
The flue gas recirculation back fire device of the utility model; Secondary recovery is counter burns through imperfect combustion flue gas is carried out; Finally make fuel reach abundant burning, the toxic gas that contains in the flue gas of discharging like this is just less, and has so also reduced operating cost for enterprise.
Description of drawings
Fig. 1: a kind of flue gas recirculation back fire device of the utility model structural representation;
Among the figure: 1: furnace shell; 2: chimney; 3: take over; 4: the flue gas recover; 5: tube connector; 6: chain furnace grate; 7: the precession sheet; 8, feeder; 9, motor; 10, hopper; 11, air inlet; 12, combustion chamber; 13, smoke chamber.
The specific embodiment
Provide the specific embodiment of the utility model below with reference to accompanying drawing, be used for the formation of the utility model is done further explain.
Embodiment 1
A kind of flue gas recirculation back fire device of present embodiment comprises furnace shell 1, and chimney 2 is installed on the furnace shell 1; Be divided into combustion chamber 12 and smoke chamber 13 in the furnace shell 1, the lower end of combustion chamber 12 is connected with chain furnace grate 6, and the sidewall of combustion chamber 12 is provided with air inlet 11; Air inlet 11 lower ends are equipped with feed arrangement, and feed arrangement comprises hopper 10, and hopper 10 lower ends are connected with feeder 8; Be provided with precession sheet 7 in the feeder 8; Precession sheet 7 advances through motor 9 driven in rotation, and a side of smoke chamber 13 is connected with flue gas recover 4 through taking over 3, and flue gas recover 4 passes through tube connector 5 and is connected with combustion chamber 12.
During use, through the flue gas recover that is provided with imperfect combustion flue gas is sent back to the combustion chamber again and carry out second-time burning, so just can accomplish abundant burning.
The flue gas recirculation back fire device of present embodiment; Secondary recovery is counter burns through imperfect combustion flue gas is carried out; Finally make fuel reach abundant burning, the toxic gas that contains in the flue gas of discharging like this is just less, and has so also reduced operating cost for enterprise.
