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, ...

Examples

Embodiment 1

[0013] Adopt the present invention to treat ammonia nitrogen waste water import ammonia nitrogen concentration 3500mg / L, processing capacity 5t / h. Nessler's reagent colorimetric method (GB7479-87) was used for analysis, and the concentration of ammonia nitrogen in the treated wastewater was 12mg / L. The steam consumption is 35kg / t.
