Abstract
The invention discloses a flue gas ejector, comprising an air joint, a tee connected with the air joint, a straight pipe connected with the other end of the tee, a taper pipe connected with the straight pipe, a flue gas adapter connected with a side pipe of the tee, and a flue gas interface flange installed on the flue gas adapter; and the tee is internally provided with an air spraying pipe. The flue gas adapter is provided with a pressure testing device. The flue gas ejector is capable of discharging flue gas smoothly and facilitates the combustion in a burner.
Description
Technical field
The present invention relates to a kind of fume emission device of burner of industrial furnace, particularly a kind of flue gas ejector.
Background technology
The fume emission device of the burner of existing industrial furnace because the defective of its structure makes fume emission not smooth, thereby makes that the burning in the burner is insufficient, influences the energy conversion rate of system, even influences the work of system.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the unimpeded flue gas ejector of a kind of fume emission.
The present invention solves the technical scheme that its problem adopts: a kind of flue gas ejector, comprise pneumatic fitting, the threeway that is connected with pneumatic fitting, the straight tube that is connected with the other end of threeway, the Taper Pipe that is connected with straight tube, the flue gas adapter that is connected with the side pipe of threeway, be located at the flue gas flange that flue gas is taken over, be provided with air lance in the described threeway.
Technique scheme also can have following improvement project: described flue gas is taken over and is provided with pressure tester.
The invention has the beneficial effects as follows: air enters threeway from the bottom, flue gas is infeeded by sidepiece, air forms negative pressure in threeway place by jet pipe ejection back in threeway, flue gas is sucked threeway discharge on top together then with after the flue gas mixing, utilize air to form jet, at the inner negative pressuren zone that forms of threeway by spout, thereby flue gas is formed injection, the design of Taper Pipe can effectively reduce resistance in the discharge process of gaseous mixture, so fume emission of the present invention is unimpeded, help the burning in the burner.The present invention is simple in structure, need not safeguard.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a main TV structure schematic diagram of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of flue gas ejector of the present invention, comprise pneumatic fitting 1, the threeway 3 that is connected with pneumatic fitting 1, the straight tube 4 that is connected with the other end of threeway 3, the Taper Pipe 5 that is connected with straight tube 4, the flue gas adapter 6 that is connected with the side pipe of threeway 3, be located at the flue gas flange 7 in the flue gas adapter 6, be provided with air lance 2 in the described threeway 3.
Technique scheme also can have following improvement project: described flue gas is taken over 6 and is provided with pressure tester 8.
Operation principle of the present invention: air is inserted by pneumatic fitting 1, air pressure generally requires 3～20KPa, air enters threeway 3 backs by spout spare air lance 2 ejection at a high speed from the bottom, this is just at negative pressuren zone of the inner formation of threeway, flue gas is taken over 6 and is connect flue gas, under the effect of negative pressure, insert flue gas and be inhaled in the threeway 3, after the air that threeway 3 internal upper parts go out with jet mixes, discharge then from passing through part straight tube 4.After having gone out straight length, the top blast pipe is the smooth discharge of mist for convenience, has made back taper spare Taper Pipe 5, and mist is discharged from Taper Pipe 5 at last.
In addition, the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
