Description
Technical field
The present invention relates to high slat-containing wastewater process field more particularly to the dry reactors of brine waste.
Background technique
A large amount of high slat-containing wastewater can inevitably be generated in the industrial production at present, traditional technique is generally contained using burning height
Salt method for waste water is handled, and is had problems in that: 1. brine wastes must be carried out cold after burning using quick cooling method
But, traditional method is all that combination cooling is carried out using a large amount of water, and the water after chilling also needs to drain into sewage treatment plant's progress
Subsequent processing, significantly waste water resource and subsequent treatment process are complicated, and cost of investment is higher；2. during the burning process, burning
Temperature is excessively high to will lead to salt fusing, and the salt of molten can penetrate into the refractory material of incinerator, lead to one layer one of refractory material
Layer delamination damage, shortens the service life of refractory material significantly；3. the thermal energy after burning cannot recycle, energy consumption is high；4. fuse salt
And other substances can generate insoluble matter in high temperature incineration, it can occluding device and system；5. the salt after chilling will become floating dust
Serious pollution is brought to surrounding enviroment.Have much room for improvement.
China Patent Publication No. CN103017177A discloses a kind of incineration disposal method for high-salinity wastewater, high slat-containing wastewater
It is indoor that a combustion is sprayed into using liquid waste spray gun, after being atomized by compressed air.It is indoor in a combustion, it assists firing by temperature feedback control
Expect consumption, volume of air supply, in-furnace temperature is made to maintain 600-700 DEG C.One combustion room generate flue gas under the action of air-introduced machine into
Enter dual firing chamber, by temperature feedback control auxiliary fuel consumption, volume of air supply in dual firing chamber, makes to maintain 1100- in furnace
1200 DEG C, and gas residence time is greater than 2 seconds.The flue gas come out from dual firing chamber enters waste heat boiler, by heat exchange, to its heat
Amount is recycled.The flue gas come out from waste heat boiler carries out fume treatment by sack cleaner and deacidifying flue gas device,
It is dusted respectively and qualified discharge after depickling.The present invention can both be such that the salinity in high slat-containing wastewater analyses by the evaporation of moisture
Noncoking out, and the harmful organic substance in flue gas can sufficiently be destroyed by fire.It is analyzed the salt of high-salt wastewater by a combustion room,
Organic exhaust gas enters progress organic matter burning in dual firing chamber, effectively prevent the service life of environmental pollution and incinerator, but one
Fire room salinity precipitation efficiency it is low, the salt block of precipitation it is easy to attach in one combustion room inner wall, cause a combustion room service life compared with
It is low, and not can guarantee entire space in furnace body producing the Control for Kiln Temperature method of setting temperature sensor of the technical solution yet
Temperature maintain between 600 ~ 700 DEG C, cause to salt out and be not thorough, increase difficulty, contracting for subsequent dual firing chamber's burning disposal
The service life of Duan Liao dual firing chamber.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of effective maintenance reactor temperatures, make whole in reactor
Temperature control greatly improves the extracting rate of saltouing of brine waste between 650 DEG C ~ 720 DEG C degree, extracting rate of saltouing up to 99.99%,
Substantially increase the high slat-containing wastewater dry reactor of the service life of reactor.
Purpose to realize the present invention provides following technical scheme: a kind of high slat-containing wastewater dry reactor, including vertical
Cylinder, the high-salt wastewater import for being opened in vertical cylinder top are provided with pressurised atomised device in import, are opened in vertical cylinder
On high-temperature flue gas air inlet, the salt outlet of vertical cylinder bottom end, the organic gas that is opened in the nearly bottom end side wall of vertical cylinder go out
Mouthful, it is characterised in that high-temperature flue gas air inlet is tangentially opened up along vertical cylinder, and high-temperature flue gas is made to form spiral shell along vertical cylinder inner wall
The downward flow-disturbing of shape is revolved, high-temperature flue gas air inlet connects heating furnace and natural gas combustion engine, and oxygenating air inlet is provided on heating furnace
Mouthful.Preferably, vertical cylinder is set as the gradually smaller multistage of diameter, high-temperature flue gas is offered on the barrel of every section of cylinder
Air inlet.Preferred: high-temperature flue gas air inlet is around the vertical cylinder center of circle at least provided with one.Preferably, organic gas
Body outlet connection escape pipe, escape pipe connecting pin are protruded into vertical cylinder, and port is close to vertical cylinder center.It effectively prevent being precipitated
Salt dust enters in escape pipe, reduces the saliferous rate of organic gas.
Preferably, height of the pressurised atomised the bottom of the device apart from nearest high-temperature flue gas air inlet is 300mm ~ 600mm.
It prevents the temperature of pressurised atomised the bottom of the device fog outlet excessively high by such setting, causes salt that blocking fog outlet is directly precipitated.
Preferably, the height ratio of adjacent size diameter section is 2:3.The diameter ratio of adjacent size diameter section is 3:2.Pass through
Such setting controls each section of temperature of dry reactor between 650 DEG C ~ 720 DEG C always, and flue gas is effectively prevent to rotate
It is cooling in dropping process, it causes to salt out efficiency decline.
The invention has the advantages that: the pre-processing devices that the present invention is to high slat-containing wastewater, dry reaction through the invention
Device effectively analyzes the salt in high slat-containing wastewater, reduces the saliferous rate of the subsequent exhaust gas into incinerator, effectively prevent subsequent
The blocking of purification and heat energy recovery pipeline, and extend the service life of incinerator.
