Description
Technical field
The utility model relates to desulfurization wastewater processing technology fields, and in particular to one kind is suitable for heat-engine plant desulfurized waste water zero
Discharge treating system.
Background technique
Limestone-gypsum Wet Flue Gas Desulfurization Process technology is the mainstream technology of Present Thermal Power factory desulfurization.But the technology is in desulfurization
Cheng Zhonghui generates a certain amount of desulfurization wastewater, and desulfurization wastewater is high concentration suspended matter, high chlorine root, high saliferous, high concentration metal are useless
Water, processing difficulty are big.In addition, country's in April, 2015 puts into effect " water prevention and cure of pollution action plan " --- how " ten, water " is realized
Desulfurization wastewater zero-emission is the problem that Present Thermal Power industry faces.
The main method of pre-treatment desulfurization wastewater has pretreatment (three headers softening clarification, tubular filter)；Concentration decrement (is steamed
MF/RO, UF/RO, UF/NF, UF/RO/ED, UF/RO/FO, UF/RO/MD etc. is concentrated in hair concentration MED, MVR, embrane method)；At solidification
It manages (natural evaporation crystallization, evaporation pond, mechanical atomization evaporation, flue spray evaporation etc.).Evaporation technique is to realize desulfurization wastewater zero
The effective technology of discharge, but directly evaporated water is larger, energy consumption cost is high；Film concentration is serious etc. there are low efficiency, fouling membrane
Disadvantage.
Summary of the invention
For the limitation for overcoming the above mainstream technology, the utility model proposes a kind of suitable for handling the energy-saving of desulfurization wastewater
System.The system is based on fume afterheat and evaporates desulfurization wastewater, and it is excellent to have that cost of investment is low with low running cost, energy consumption is relatively small etc.
Gesture, it is contemplated that have preferable application value.
Utility model is achieved through the following technical solutions:
A kind of energy-saving system suitable for handling desulfurization wastewater, including deduster, desulfuration absorbing tower and waste water evaporating column.
Evaporating column and flue are relatively independent with flue by pipeline connection.Air-introduced machine is set in pipeline, the flue gas in flue is introduced into evaporation
In tower.Atomizing spray layer is set in evaporating column, circulating pump, circulating pump and evaporating column inside are provided with outside evaporating column and atomization is sprayed
Drenching layer connection, and the connection position inside circulating pump and waste water evaporating column is located at below atomizing spray layer.
The lower section of desulfuration absorbing tower couples gypsum dehydration equipment, the wet desulphurization waste water warp after gypsum belt dewaterer
Waste water surge tank source of the supernatant as spray water after precipitation is crossed, spray water reaches atomizing spray layer by circulating pump, with
Low-temperature flue gas contact, mixing, the moisture in waste water is taken away by low-temperature flue gas waste heat.In addition, for the level for maintaining desulphurization system
Weighing apparatus, by waste water surge tank, supernatant can also be used as the flushing water of demister after precipitation.
Plate and frame filter press is set below evaporating column, plate and frame filter press simultaneously with waste water evaporating column and waste water surge tank connection.
On the one hand solid matter filters pressing in waste water evaporating column is sludge by plate and frame filter press, later outward transport landfill, another aspect filters pressing
Filtrate out returns to surge tank.
Utility model compared with prior art, has the following advantages and benefits:
(1) this programme utilizes fume afterheat low-temperature evaporation desulfurization wastewater, does not need to consume other external heat sources, energy-saving ring
It protects, operating cost is low；
(2) flue facture is compared, the waste water evaporating column of this programme is independently arranged at outside flue with flue connection, is not required to
Anti-corrosion measure is taken flue inner wall, and cost of investment is lower；
(3) this programme structure is simple, easy to implement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model:
Wherein: 1- flue, 2- deduster, 3- pipeline, 4- blower, 5- waste water evaporating column, 6- circulating pump, 7- desulfurization absorb

Specific embodiment
Illustrate the purpose of this utility model, technical solution in order to clearer, it is practical new that Detailed description of the invention sheet will be compareed below
The specific embodiment of type.
As shown in Figure 1, a kind of energy-saving system for handling desulfurization wastewater, including the evaporation of deduster, desulfuration absorbing tower, waste water
Tower, waste water surge tank etc..Demister is provided in desulfuration absorbing tower, demister passes through circulating pump and waste water surge tank connection.It is useless
Be provided with atomizing spray layer in water evaporation tower, atomizing spray layer by circulating pump also with waste water surge tank connection.Waste water surge tank
For storing the waste water after desulfurization is concentrated, the supernatant after precipitating reaches atomizing spray layer by circulating pump, as spraying
The source of water.Atomizing spray layer sprays drop and smoke contacts, utilizes waste heat evaporating waste water drop.To maintain desulphurization system horizontal
Weighing apparatus, the supernatant of waste water surge tank is transported to demister also by circulating pump, for rinsing demister.
Waste water evaporating column is set between deduster and desulfuration absorbing tower, passes through pipeline and flue connection.Setting in pipeline
There is air-introduced machine, the low-temperature flue gas in flue is introduced by air-introduced machine, is evaporated to waste water evaporating column.
The lower part of waste water evaporating column and plate and frame filter press connection, after plate and frame filter press filters pressing, obtained sludge into
Row outward transport landfill disposal.
Above-described specific embodiment has carried out specific description to this case.
