Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
With reference to Fig. 1: a kind of flue gas reutilization system, comprise cooling tower (not shown), the side of cooling tower is provided with exhanst gas outlet, exhanst gas outlet is connected with fume pipe 1, the end of fume pipe 1 is provided with branched pipe, first branched pipe 2 connects the first combustion furnace 3, second branched pipe 4 through the first flue gas control valve 21 and connects the second combustion furnace 5, first combustion furnace 3 and the second combustion furnace 5 through the second flue gas control valve 41 and be connected the first bamboo bits drying oven 6 and the second bamboo bits drying oven 7 respectively.Wherein used for cooling tower in cooled flue gas, owing to carrying bamboo bits oil gas in flue gas, the flue gas obtaining vinifera palm oil and be not partly liquefied after cooling tower cooling.Combustion furnace is used for adding heat smoke to be made it to become high-temperature flue gas, then enter bamboo bits drying oven to bamboo bits dry.Due to bamboo bits quantity and smoke yields more, therefore the present embodiment provides two combustion furnaces and two bamboos bits drying ovens, to improve flue gas utilization rate.The first flue gas control valve 21 in the present embodiment and the second flue gas control valve 41 are hand-operated valve, by operating personnel's Non-follow control.Fume pipe 1 being connected with air blast 8, for being blasted in branched pipe fast by the flue gas in fume pipe 1, and then entering the first combustion furnace 3 and the second combustion furnace 5 fast, thus shorten flue gas time of delivery, raise the efficiency.
The first oxygen-enriched inlet 32, first branched pipe 2 that first combustion furnace 3 comprises furnace shell 31, furnace chamber and is located at the first furnace chamber bottom is connected with the side of furnace chamber.First oxygen-enriched inlet 32 and the equipment connection carrying oxygen-enriched air, as connected oxygen rifle.Adopt oxygen-enriched air to add heat smoke, can either burning velocity be accelerated, promote combustion completion, the ignition temperature of fuel can be reduced again and reduce the tail-off time, thus reaching energy-efficient object.The furnace shell of the first combustion furnace is built into by brick, high insulating effect, can greatly reduce the loss of fume afterheat, improves flue gas utilization rate.
Second combustion furnace 5 comprises front latter linked combustion chamber 51 and gas mixer chamber 52, and gas mixer chamber 52 is located at the front side of combustion chamber 51.The front end of gas mixer chamber 52 is provided with the second oxygen-enriched inlet 521, and the top of gas mixer chamber 52 connects the second branched pipe 4.The furnace shell of the second combustion furnace 5 is stainless steel.Before and after second combustion furnace 5 adopts, the horizontal design of structure, makes the thermal efficiency greatly improve.
First branched pipe 2 is made up of three tipping tubes at an angle.The angular dimension between three tipping tubes is controlled according to the position of fume pipe 1 and the first combustion furnace 3.Angle between the first two tipping tube in the present embodiment is 135 °, and the angle between the tipping tube of end and second tipping tube is 165 °.Because fume pipe 1 is comparatively near apart from the position of the first combustion furnace 3, does not therefore select the pipeline of the level that is designed to by the first branched pipe 2, vertically composition, the flowing velocity of flue gas can be reduced like this; Select tipping tube to tilt and the lower flow velocity that can improve flue gas from eminence, flue gas is inputed in the first combustion furnace 3 fast.
Second branched pipe 4 is made up of horizontal tube 41, bend pipe 42 and VERTICAL TUBE 43, and fume pipe 1 is communicated with through horizontal tube 41, bend pipe 42 and VERTICAL TUBE 43 top with the second combustion furnace 5 successively.Because fume pipe 1 is comparatively far away apart from the position of the second combustion furnace 5, does not therefore select to adopt tipping tube, the quantity of tipping tube can be increased like this, raise the cost.
The pipe diameter of the first branched pipe 2 in this example is less than the pipe diameter of the second branched pipe 4, this is because fume pipe 1 is far away apart from the position of the second combustion furnace 5, therefore the pipe diameter of the second branched pipe 4 is strengthened, although flow of flue gas is slow, but contact area is large, the exhaust gas volumn of once-through is many, synchronous with the first combustion furnace 3 to realize.
The present embodiment can realize drying the bamboo bits in multiple bamboo bits drying oven according to the quantity of bamboo bits simultaneously, shortens drying time, increases work efficiency.
