Abstract
The utility model relates to a device for leading out smoke from a boiler, which relate to boiler smoke system field and is composed of a smoke channel, a blower fan and a jetting and sucking tube. Because two lateral surfaces of the smoke channel are designed with an assembly opening and an air inlet, the jetting and sucking tube is arranged at an inner cavity of the smoke channel, is parallel to a smoke channel passage and is connected with the blower fan outlet. The utility model has the advantages that high pressure wind which generated by the blower fan enters the smoke channel through the jetting and sucking tube, and definite negative pressure is formed in the smoke channel to lead out the smoke; the abrasion and the acid corrosion of a blower fan impeller, which are caused because the smoke directly enters the blower fan are avoided, and the service life of the blower fan is prolonged.
Description
The utility model relates to the boiler technology field, particularly relates to the boiler tail flue gas ejector.
Existing boiler tail flue gas to draw a kind of be that blower fan is contained in before the desulfurizing dust-collector, flue gas is during through blower fan, draught fan impeller will be subjected to the wearing and tearing of ash-laden gas particle; Another kind is that blower fan is contained in after the desulfurizing dust-collector, contains certain moisture content through the flue gas behind the desulfurizing dust-collector, must cause draught fan impeller acid corrosion, dust after entering blower fan again, finally destroys the blower fan dynamic balancing, causes blower fan to damage.
The purpose of this utility model provides a kind of boiler smoke ejector, boiler tail flue gas is without blower fan, but the high-pressure blast that is produced by blower fan enters flue by injecting tube, the interior negative pressure that produces of flue is drawn flue gas, and draught fan impeller is subjected to soot dust granule wearing and tearing and acid corrosion when avoiding flue gas to enter blower fan.
For achieving the above object, the technical solution of the utility model is: it is by flue, blower fan, injecting tube are formed, the flue two sides have installing port and air inlet respectively, injecting tube the flue inner chamber and with the flue channel parallel, installing port is fixed with the lid fitted bolt, and air inlet cooperates fixedly connected with the fan outlet outer wall, and the fan outlet edge cooperates fixedly connected with injecting tube inclined-plane one end.
The utility model compared with the prior art, because the flue inner chamber is equipped with injecting tube and injecting tube is connected with fan outlet, the high-pressure blast that blower fan produces enters flue by injecting tube, make and produce negative pressure in the flue, flue gas is drawn, the phenomenon of impeller acid corrosion when impeller is subjected to soot dust granule wearing and tearing and the flue gas after dedusting and enters blower fan when avoiding flue gas to enter blower fan, the service life of improving blower fan.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Be illustrated as boiler smoke ejector structure master and look cutaway view;
The boiler smoke ejector, it is by flue, blower fan, injecting tube are formed, and square or circular flue 1 both sides have installing port 7 and square air inlet 8 respectively, and injecting tube 2 is square or hemispherical dome shape, injecting tube 2 square ends have the inclined-plane, injecting tube 2 is at flue 1 inner chamber, and with flue 1 channel parallel, installing port 7 is fixed with lid 3 fitted bolts, air inlet 8 is fixed with blower fan 4 air outlet outer wall fitted bolts, and blower fan 4 air outlet edges cooperate solid welding with injecting tube 2 inclined-planes one end.During use, the flue 1 one end exhanst gas outlets that flue 1 inner chamber injecting tube 2 high-pressure blasts exported an end cooperate flange to fix with desulfurizing dust-collector 5 smoke inlets, and flue 1 other end smoke inlet cooperates flange to fix with the outlet of boiler 6 tail flue gas.
Claims (3)
1. boiler smoke ejector, it is made up of flue, blower fan, injecting tube, it is characterized in that: the flue two sides have installing port and air inlet respectively, injecting tube the flue inner chamber and with the flue channel parallel, installing port is fixed with the lid fitted bolt, air inlet cooperates fixedly connected with the fan outlet outer wall, the fan outlet edge cooperates fixedly connected with injecting tube inclined-plane one end.
2. boiler smoke ejector as claimed in claim 1 is characterized in that: flue is square or circular.
3. as claim 1,2 described boiler smoke ejectors, it is characterized in that: injecting tube is square or hemispherical dome shape.
