The application discloses a boiler waste heat recycling device and relates to the technical field of waste heat utilization and environmental protection, which comprises a boiler module and a waste heat recycling module; the waste heat recycling module is used for recycling the heat in flue gas after fuel combustion in the boiler module and recycling the heat for fuel combustion; the waste heat recycling module comprises a protective shell, and a first heat conduction component, a second heat conduction component, a heat exchange component, an air injection component and a pressure increasing component are installed in the protective shell. The application has the advantages that the flue gas waste heat is recycled in two stages, the first stage recycling is used for heating air entering a combustion chamber, reducing invalid heat consumption and improving combustion efficiency, and the second stage recycling is used for increasing the air pressure entering the combustion chamber, so that the contact area of fuel and air is expanded, fuel combustion is more sufficient, the waste heat recycling rate is higher, and the utilization effect is more obvious.

The present application belongs to the field of burners, and discloses a deflectable wall-type tangential circle boiler burner and a working method. The deflection assembly adopts a transmission mode of servo motors, screw rods and solid rods, which can realize accurate angle adjustment. This makes the burner nozzle able to adjust the direction in real time according to the needs, and optimizes the distribution of combustion gas flow in the furnace. Especially under the conditions of boiler load change or different fuels, this flexible adjustment capability helps to improve the combustion efficiency. By accurately adjusting the deflection angle of the nozzle, the present application can make the combustion gas flow evenly distributed in the furnace, reducing the phenomenon of incomplete combustion. The direction of the burner nozzle can be dynamically adjusted according to different working conditions, so as to better adapt to the needs of different loads and different fuels, and finally improve the overall combustion efficiency of the boiler. The adjustable deflection angle of the present application makes the burner nozzle able to adjust according to the distribution of the temperature in the furnace, effectively avoiding the areas with excessively high or low temperature.

This invention belongs to the field of waste gas treatment technology, specifically disclosing a flare gas incineration treatment system for EVA production. The system includes a daily gas buffer tank and an emergency gas buffer tank, each connected in series with a liquid separator, a water seal tank, and a cooler. The gas outlets of the two coolers are connected to an incinerator, and the flue gas outlet of the incinerator is connected in series with an induced draft fan and a chimney. Addressing the safety risks, such as explosions, posed by direct combustion of flare gas generated during EVA production, this invention achieves safe, efficient, and compliant emissions of flare gas by classifying and collecting the flare gas, separating it into liquids, applying a water seal, pre-treating it with cooling, and precisely monitoring key parameters, combined with efficient incineration in an incinerator. This solves the problem that direct combustion of flare gas containing hydrocarbons such as ethylene, vinyl acetate, and organic solvents generated during EVA production can easily lead to explosions or flameout accidents due to gas composition imbalance.
