But the flue gas discharging device installed at the top end of the existing cremator has the defects of insufficient ejection pressure and lower ejected flue gas flow.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a smoke emission ejector.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a fume emission ejector, includes the flue gas pipe, the lateral wall intercommunication of flue gas pipe has the air duct, the one end that the flue gas pipe was kept away from to the air duct has the air inlet reducing pipe through flange and bolt-up connection, the opening side edge of air inlet reducing pipe is provided with draught fan flange, the top of flue gas pipe is provided with the exhanst gas outlet to install control flap at the exhanst gas outlet, the bottom of flue gas pipe is provided with the flue gas pipe flange, the flue gas pipe passes through the flue gas delivery union coupling on flue gas pipe flange and cremator top, the inner chamber middle part of flue gas pipe is provided with a pair of diffusion tube that is symmetry from top to bottom, and is a pair of be connected with the hybrid tube between the diffusion tube.
Preferably, a diversion nozzle is arranged on one side, away from the air inlet reducer, of the air pipe, and the diversion nozzle is bent and inserted into the diffusion pipe.
Preferably, the aperture of the flow guide nozzle is one half of that of the mixing pipe, and the conical chamfer angle of the diffusion pipe is fifteen degrees.
The utility model provides a pair of smoke emission ejector, beneficial effect lies in: air is sucked by a draught fan, enters an air pipe through an inlet and is jetted out through a flow guide nozzle, according to the Venturi principle, the diameter and the height of the air pipe are calculated to form a certain proportion with the diameter of a smoke pipe, the position and the opening angle of the flow guide nozzle are calculated to form a certain proportion with a mixing pipe, the lower part of the flow guide nozzle is conical, the design is favorable for accelerating the air and further increasing the aerodynamic force, the upper part of the flow guide nozzle is inverted conical and is favorable for uniformly diffusing the air, when the air enters the flow guide nozzle through the air pipe and uniformly diffuses to the mixing pipe at a certain angle, the inside of the smoke pipe forms a vacuum state, the smoke enters from the inlet, and after the air is accelerated through the middle cone of the smoke pipe, the smoke and the air are mixed and further discharged through the diffusion pipe, and the air is accelerated and uniformly diffused in an umbrella shape, so that the principle similar to a medical injection syringe is formed in the mixing pipe, the internal pressure of the smoke tube is far lower than the pressure of the diffusion tube, so that a large amount of smoke is brought into the smoke tube to be discharged, and the smoke discharge efficiency is effectively improved.
