Abstract
The utility model discloses a smoke ejector, comprising an air connector, a tee connected with the air connector, a straight pipe connected with the other end of the tee, a taper pipe connected with the straight pipe, a smoke connecting pipe connected with side pipes of the tee and a smoke interface flange arranged on the smoke connecting pipe, wherein an air nozzle is arranged inside the tee and a pressure testing device is arranged on the smoke connecting pipe. The utility model has the advantages of smooth smoke emission and favourability for the combustion inside a combustor.
Description
Technical field
The utility model 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 flue gas ejector that provides a kind of fume emission unimpeded is provided the purpose of this utility model.
The technical scheme that the invention for solving the technical problem adopted is: 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 beneficial effects of the utility model are: 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 discharges on top then with after the flue gas mixing together, utilize air to form jet by spout, at the inner negative pressuren zone that forms of threeway, thereby flue gas is formed injection, the design of Taper Pipe can effectively reduce resistance in the discharge process of gaseous mixture, so the utility model fume emission is unimpeded, help the burning in the burner.The utility model is simple in structure, need not safeguard.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of flue gas ejector of the utility model, 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.
The utility model operation principle: 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.
Air lance 2 of the present utility model can be regulated relative position in threeway 3, the vacuum magnitude in the convenient control threeway 3 is measured by pressure tester 8 size of negative pressure, convenient debugging and control.Straight tube 4 has certain length, so that the formation of negative pressure.Material material of the present utility model can be selected carbon steel or stainless steel for use according to the height of flue-gas temperature.The utility model utilizes normality (30 degree～100 degree) high pressure, and (3～20KPa) air carry out discharging out of the furnace behind the injection to high-temperature flue gas (100 degree～1000 degree) by injector.
In addition, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
