Efficient concentration treatment system and method for organic waste liquid

Abstract: The invention discloses an efficient concentration treatment system for organic waste liquid. The system comprises a combustion chamber, an evaporation chamber, a gas-liquid separator, a spray tower,a negative pressure evaporation chamber, a secondary combustion chamber, an organic waste liquid preheater, an air preheater and a dust collector. The invention further discloses an efficient concentration treatment method for the organic waste liquid. Four optional working modes can be provided. Accordingly, the pollution problem caused by the phenomenon that in the evaporation concentration process, flue gas contains volatile organic matter can be solved while efficient treatment of organic waste liquid such as landfill leachate and high salinity industrial waste liquid which is highly corrosive, viscous and prone to crystallization and scaling is guaranteed.

Environmentally-friendly recycling device for exhaust steam of gathering tank

Abstract: The invention discloses an environmentally-friendly recycling device for exhaust steam of a gathering tank, and belongs to the technical field of oil exploitation. The device is characterized in that a spray tower is utilized to perform cold and heat exchange for high-temperature exhaust steam and separate non-condensate gas; then an oil-water separator is used for separating the non-condensate gas into an oil part and a water part; finally the water part is recycled to the spray tower under the effects of a circulating water pump and a cooling tower, and at the same time the oil part is recovered; the heat of the exhaust steam is outwards conveyed to mix and heat. With the adoption of the device, the oil gas resource is recovered, and the technical effect of reducing the pollution of the exhaust steam to the environment is reduced.

Denitrification system and method for industrial furnace or kiln

Abstract: The invention discloses a denitrification system for an industrial furnace or kiln The denitrification system is characterized by comprising a furnace or kiln flue and an alkali liquor spray tower, wherein atomizing nozzles or spray guns are uniformly distributed on the upper part of the flue; and the outlet of the flue is connected with a flue gas inlet of the alkali liquor spray tower, and a spray header is arranged in the spray tower The invention also discloses a denitrification method for the industrial furnace or kiln The denitrification method comprises the following steps of: spraying ammonia or other reducing agents in a flue gas pipeline by adopting a selective non-catalytic reduction (SNCR) technology in a high-temperature area of flue gas to perform primary denitrification; and performing secondary denitrification treatment at the tail end of the flue gas by adopting an alkali absorption method, and performing denitrification by combining two processes When denitrification is performed in the high-temperature area by spraying the ammonia, the denitrification efficiency can reach 50 to 75 percent; when denitrification is performed in the spray tower by adopting the alkali absorption method, the denitrification efficiency can reach 60 to 75 percent; and through combined treatment, the denitrification efficiency can reach 80 to 95 percent is achieved
