Abstract
The utility model discloses a serial ejector, which is provided with a nozzle, a plurality of stages of gas sucking and mixing eject pipes and a gas sucking and mixing pipe, wherein an ejecting device has the effects of ejecting low-energy gas with high-energy gas to mix the gases, forming required residual pressure at the tail end of the ejecting device, meeting various application requirements and outputting necessary gas flow. In the serial ejector, the ejecting device is connected once or for a plurality of times in a series for use; and the ejector has the effect of ejecting mixed gas of first eject gas and ejected gas to serve as eject gas again, so that the supply of the ejected gas is increased to meet the application requirement. For example, a serial ejector structure is adopted in a gas burner, gas can eject sufficient combustion-supporting air into the gas sucking and mixing pipe without secondary air combustion-supporting, so that the gas is fully premixed with air to combust, thermal efficiency of combustion is increased, exhaust emission is reduced, and energy conservation and environmental friendliness are guaranteed. The serial ejector is mainly used for the fields of industrial combustors, commercial combustors, civil combustors and the like. The industrial combustors are mainly used for industrial gas (oil) boilers; the commercial combustors are mainly used for commercial gas (oil) boilers, large stoves and Chinese meal stoves; and the civil combustors are mainly used for household gas stoves and household gas water heaters. The serial ejector has a simple structure and is easy to manufacture, apply and popularize.
Description
Technical field:
The present invention relates to a kind of plural serial stage injector, it is mainly used in above industrial burner, commercial burner and the civilian burner etc.Industrial burner mainly is used on industry combustion (oil) gas boiler; Commercial burner mainly is used on commercial combustion (oil) gas boiler, large stove and the Chinese meal stove; Civilian burner mainly is used on household gas range and the domestic gas-fired water heater.When the plural serial stage injector was used on the burner, it can obtain abundant by injection gas, combustible gas physical efficiency and more combustion-supporting gas is mixed, thereby make burning more abundant, had improved combustion thermal efficiency, had reduced toxic emission.
Background technology:
The domestic and international at present injection burner that adopts (or claiming atmospheric burner), its structure mainly is by the disposable injection combustion-supporting gas of finishing of fuel gas.Disposable injection can only provide the combustion-supporting gas of part to enter air intake duct, so also need provide the secondary combustion-supporting gas to help burning outside flame once more, has so just formed double-layer flame, its flame envelope is the diffusion type burning, it is insufficient to burn, and the thermal efficiency is low, and toxic emission is big.The plural serial stage injector has thoroughly solved the problems referred to above, by the plural serial stage injection, can provide the needed combustion-supporting gas of completing combustion to enter air intake duct, make fuel gas and the combustion-supporting gas can be fully premixed by theoretical equivalent, it is insufficient the burning that the diffusion type burning causes so can not occur, has significantly improved the combustion thermal efficiency of burner.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly obtain enough by the method for injection gas more easily, in the use of burner, the series connection injector will make combustion gas more abundant, thereby reach the purpose of energy-conserving and environment-protective.
A kind of inline mixer, described series connection injector is provided with nozzle, one or more air-breathing mixing induction tunnels and air-breathing mixing tube.
Beneficial effect of the present invention, described series connection injector is provided with nozzle, one or more air-breathing mixing induction tunnels and air-breathing mixing tube.Its effect be with the mist behind the injection last time as injection gas injection once more, thereby increase by injection gas supply to satisfy instructions for use.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is described in detail
Accompanying drawing: be principle of the invention schematic diagram:
The specific embodiment:
As shown in drawings, a kind of series connection injector, the injection gas 1 that has certain pressure enters air-breathing mixing induction tunnel 7 by nozzle 8, and with enter into air-breathing mix induction tunnel 7 once be mixed into mixed once gas 4 by injection gas 2.Mixed once gas 4 enters air-breathing mixing tube 6 and is mixed into secondary mist 5 with secondary by injection gas 3 then.So formation secondary or repeatedly mist.
Claims (1)
1. series connection injector, described series connection injector is provided with nozzle and one or more air-breathing mixing induction tunnels and air-breathing mixing tube.It is characterized in that nozzle is connected use with one or more air-breathing mixing induction tunnels and air-breathing mixing tube with series system, form the series connection injector, last time mist was as injection gas injection once more.
