Embedded double-fluid efficient energy-saving deamination system

Abstract

An embedded double-fluid efficient energy-saving deamination system belongs to the technical field of sewage processing. Equipment mainly comprises a lifting pump, a circulating pump, a heat exchanger, a flow-pushing pressurizing blower fan, and an embedded double-fluid efficient energy-saving deamination tower. In a technological process, ammonia-nitrogen wastewater subjected to heat exchanging enters the tower body, and subjected to deamination by flow-pushing pressurizing steam and fresh steam; and at the same time, ammonia-containing steam is absorbed by circulating ammonium sulfate and circulating dilute sulfuric acid and an ammonium sulfate solution is obtained, and purified steam is cycled for usage by a flow-pushing pressurizing kettle. The invention provides the ammonia-nitrogen wastewater processing equipment which is high in efficiency, low in steam consumption and small in occupied space, and also provides the ammonia-nitrogen wastewater processing technology.

Description

technical field [0001] The present invention relates to the field of manufacturing industrial wastewater separation equipment, in particular to a process technology involving the use of a tower-type steam push-flow pressurization and an embedded dual-fluid process technology to achieve simultaneous treatment and resource utilization of ammonia-nitrogen wastewater and recycling hot system. Background technique [0002] Ammonia nitrogen pollution is mainly caused when the concentration of ammonia nitrogen in the water body increases, which will lead to eutrophication of the water body and cause a large number of aquatic organisms to grow. When these organisms die, they are decomposed by microorganisms in the water and consume a lot of oxygen, resulting in severe hypoxia in the water, resulting in the death of a large number of aquatic organisms, and the corrupted water quality makes the microorganisms reproduce in large numbers, resulting in turbidity and stench in the water, ...

Problems solved by technology

However, the existing stripping process has many shortcomings, such as large equipment footprint and high energy consumption, especially in terms of steam unit consumption, resulting in high cost of ammonia nitrogen wastewater treatment, which makes enterprises unwilling or unable to bear the treatment costs
