Abstract
The utility model discloses a static mixer for air and smoke, which comprises an air inlet pipe and a smoke circulation pipe connected with the side part of the air inlet pipe and is characterized in that multiple spaced guide plates are fixed on the opposite two side walls of the air inlet pipe at the junction with the smoke circulation pipe, wherein one side wall of the air inlet pipe is located in the smoke circulation pipe; and multiple smoke inlets are formed between adjacent two guide plates of the side wall. The static mixer disclosed by the utility model remarkably improves the uniformity of the mixed gas and improves the burning effect.
Description
Technical field
The utility model relates to a kind of static mixer for air and flue gas.
Background technology
At boiler industry, often the flue gas in the back-end ductwork is reclaimed, mixes with air that the back is used for burning or combustion-supporting, present, blast pipe all mixes by gas flow automatically with after the flue gas recirculation pipe links to each other, and the uniformity of its mixing is relatively poor, has influenced combustion efficiency.
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, and a kind of static mixer for air and flue gas is provided, and it can significantly improve the uniformity of gaseous mixture, has improved combustion efficiency.
For achieving the above object, static mixer for air and flue gas of the present utility model, blast pipe, the flue gas recirculation pipe that links to each other with the blast pipe sidepiece, it is characterized in that setting firmly several piece deflector at interval in the blast pipe two lateral walls with flue gas recirculation pipe connecting place, wherein sidewall of blast pipe is positioned at the flue gas recirculation pipe, has several smoke inlets between adjacent two deflectors of this sidewall.
During use: flue gas is separated from several smoke inlets and enters between each deflector, mixes with air in the blast pipe again, and the uniformity of its gaseous mixture significantly improves, and can improve combustion efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the static mixer that should be used for air and flue gas, blast pipe 1, the flue gas recirculation pipe 19 that links to each other with blast pipe 1 sidepiece, set firmly several piece deflector 22 at interval in the blast pipe two lateral walls with flue gas recirculation pipe 19 connecting places, wherein blast pipe 1 sidewall is positioned at flue gas recirculation pipe 19, has several smoke inlets 23 between adjacent two deflectors 22 of this sidewall.
During use: flue gas is separated from several smoke inlets 23 and enters between each deflector 22, mixes with air in the blast pipe 1 again, and the uniformity of its gaseous mixture significantly improves, and can improve combustion efficiency.
